Description

火葬系統 Cremation system

本發明涉及一種火葬系統，特別涉及具有發電系統的火葬系統。 The present invention relates to a cremation system, and more particularly to a cremation system having a power generation system.

以往的火葬系統，利用冷卻器等將在火葬爐產生的高溫的排放氣體冷卻後，利用集塵裝置進行灰塵的除去處理，之後，利用催化裝置將二噁英類等除去，最終經由煙囪排放到大氣中。即，以往的火葬系統中，一般不會將高溫的熱能再利用，而是就此廢棄。 In the conventional cremation system, the high-temperature exhaust gas generated in the cremation furnace is cooled by a cooler or the like, and the dust is removed by the dust collecting device. Then, the dioxin is removed by the catalytic device, and finally discharged to the chimney. In the atmosphere. That is, in the conventional cremation system, high-temperature heat energy is generally not reused, but is discarded.

但是，近年來火葬系統中，也謀求提高火葬系統整體的能源效率而實現節能，與此同時，還要求構築尊重人(遺體)的尊嚴的火葬系統。 However, in recent years, the cremation system has also sought to improve the energy efficiency of the entire cremation system to achieve energy conservation, and at the same time, it is required to construct a cremation system that respects the dignity of the human being (the remains).

為實現節能，作為第一現有技術，存在有專利文獻1(JP特開2012-13266公報)中記載的發電系統以及火葬爐，並且記載了如下內容：在火葬系統中組合有發電系統，使用在火葬爐產生的高溫的熱能，利用熱交換器產生蒸汽，利用該蒸汽驅動蒸汽渦輪機進行發電，從而有效利用在火葬爐產生的熱能。 In the first prior art, there is a power generation system and a cremation furnace described in the patent document 1 (JP-A-2012-13266), and a power generation system is incorporated in a cremation system. The high-temperature heat generated by the cremation furnace uses a heat exchanger to generate steam, which is used to drive a steam turbine to generate electricity, thereby effectively utilizing the heat energy generated in the cremation furnace.

接著參照第10圖，針對第一現有技術進行詳細說明。在第10圖中，火葬爐101具有作為鍋爐的功能，由供水泵106供給的水利用火葬爐101內高溫的熱而汽化，水蒸汽被送到汽水分離器102。利用汽水分離器102 而將水滴除去的蒸汽，被送到發電機103而驅動蒸汽渦輪機進行發電。為驅動蒸汽渦輪機而使用了之後的低壓蒸汽，被送到從冷卻塔105接受冷卻水的供給的復水器104，凝結成水，並被送到熱水箱107，而向著火葬爐101循環。這樣，本公報記載的火葬爐是使焚燒爐本身鍋爐化，使熱效率提高。 Next, the first prior art will be described in detail with reference to FIG. In Fig. 10, the cremation furnace 101 has a function as a boiler, and the water supplied from the water supply pump 106 is vaporized by the high temperature heat in the cremation furnace 101, and the water vapor is sent to the steam separator 102. Utilizing the steam separator 102 The steam removed by the water droplets is sent to the generator 103 to drive the steam turbine to generate electricity. The subsequent low-pressure steam is used to drive the steam turbine, and is sent to the rehydrator 104 that receives the supply of the cooling water from the cooling tower 105, condensed into water, and sent to the hot water tank 107 to circulate toward the cremation furnace 101. Thus, the cremation furnace described in this publication is to boiler the incinerator itself to improve the heat efficiency.

另外，作為組合有發電裝置的火葬設備的第二現有技術，存在有專利文獻2(JP特開2010-133693公報)中記載的移動式一體型火葬設備，參照第11圖進行說明。在本公報中，供電裝置115供給用於運轉焚燒爐111、冷卻裝置112a、112b、集塵裝置113a、113b以及餘熱排出裝置114的電力。由此，不需要從外部接受電力，因此，實現了移動式一體型火葬設備。 In the second prior art, a mobile integrated cremation device described in the patent document 2 (JP-A-2010-133693) is described with reference to FIG. In the present specification, the power supply device 115 supplies electric power for operating the incinerator 111, the cooling devices 112a and 112b, the dust collecting devices 113a and 113b, and the residual heat discharging device 114. Thereby, it is not necessary to receive electric power from the outside, and therefore, a mobile integrated cremation apparatus is realized.

另外，作為有效利用低溫且小容量的餘熱進行發電的第三現有技術，參照第12圖，針對專利文獻3(JP專利第4875546號公報)中記載的餘熱發電裝置、餘熱發電裝置的工作介質蒸汽加熱度控制方法進行說明。 In addition, as a third prior art that is capable of generating electricity by using a low-temperature and a small-capacity waste heat, the working medium vapor of the waste heat power generation device and the waste heat power generation device described in Patent Document 3 (JP Patent No. 4875546) is referred to in FIG. The heating degree control method will be described.

第12圖是本公報記載的餘熱發電裝置的結構圖，將來自餘熱源129的熱水供給到蒸汽產生器121而對液態的工作介質進行加熱，產生工作介質的蒸汽。接著，將該工作介質的蒸汽供給到液滴分離器122。利用壓力感測器126和溫度感測器127分別測定該工作介質的蒸汽的壓力和溫度，並將這些資訊傳遞到控制台128。從而壓力和溫度通過控制台128被控制的工作介質的蒸汽，使渦輪機123旋轉，進而驅動與渦輪機連接著的高速發電機進行發電。 Fig. 12 is a configuration diagram of the waste heat power generation device described in the present specification, and the hot water from the residual heat source 129 is supplied to the steam generator 121 to heat the liquid working medium to generate steam of the working medium. Next, the steam of the working medium is supplied to the droplet separator 122. The pressure and temperature of the steam of the working medium are measured by pressure sensor 126 and temperature sensor 127, respectively, and the information is communicated to console 128. Thus, the pressure and temperature are passed through the steam of the working medium controlled by the console 128, causing the turbine 123 to rotate, thereby driving a high speed generator connected to the turbine to generate electricity.

來自渦輪機123的工作介質的蒸汽被凝結器124冷卻而成為液體，並且經由供液泵125被送至蒸汽產生器121，再次生成工作介質的蒸汽。這樣，進行低沸點(40℃左右)的工作介質的循環。該餘熱發電裝置 參照來自於壓力感測器126和溫度感測器127的壓力和溫度運算加熱度，對供液泵125的旋轉速度進行增減來控制液態的工作介質的流量，以使得該運算值與預先設定的加熱度一致。通過進行這樣的控制，可將加熱度確保為一定，有效回收餘熱，進行發電。 The steam from the working medium of the turbine 123 is cooled by the condenser 124 to become a liquid, and is sent to the steam generator 121 via the liquid supply pump 125 to regenerate the steam of the working medium. Thus, the circulation of the working medium having a low boiling point (about 40 ° C) is performed. The waste heat power generation device Referring to the pressure and temperature from the pressure sensor 126 and the temperature sensor 127 to calculate the heating degree, the rotation speed of the liquid supply pump 125 is increased or decreased to control the flow rate of the liquid working medium, so that the calculated value and the preset value are set. The heating is consistent. By performing such control, the degree of heating can be ensured to be constant, and waste heat can be efficiently recovered to generate electricity.

進一步，作為不基於餘熱流量或者餘熱溫度的變化而得到穩定的發電輸出的第四現有技術，參照第13圖針對專利文獻4(JP特開平10-184316號公報)中記載的廢熱利用的發電控制裝置進行說明。 Further, as a fourth prior art that does not generate a stable power generation output based on a change in the heat-flow rate or the heat-recovery temperature, the power generation control of the waste heat utilization described in the patent document 4 (JP-A No. 10-184316) The device is described.

第13圖是本公報記載的發電設備的方塊圖，包括：控制流入到蒸汽渦輪機131的蒸汽流量用的蒸汽流量控制系統；控制蒸汽渦輪機的入口壓力的蒸汽壓力控制系統；控制各蒸汽分離器132a~132c的各熱水液位的熱水液位控制系統。另外，具有：控制高壓、中壓、低壓的各蒸汽分離器132a~132c的剩餘熱水的溫度的熱水溫度控制系統；控制復水器133的水位水平的復水器液位控制系統；控制向冷卻塔134補給的補給水量，以使得冷水塔134的水位水平為設定值的補給水量控制系統；控制冷卻塔134的冷卻水溫度的機內溫度控制系統。從而使用這些控制系統，使得電力負載的變動、流入蒸汽渦輪機的蒸汽流量的變動、餘熱蒸汽流量的變動以及壓力變動、復水器的機內溫度變動、冷卻水量以及餘熱熱交換器出口的溫度變動、冷卻塔的液位變動等穩定化，進行高效率的發電。 Figure 13 is a block diagram of the power generating apparatus described in the present specification, including: a steam flow control system for controlling the flow rate of steam flowing into the steam turbine 131; a steam pressure control system for controlling the inlet pressure of the steam turbine; and each steam separator 132a is controlled ~132c hot water level control system for each hot water level. In addition, there is a hot water temperature control system for controlling the temperature of the remaining hot water of each of the steam separators 132a to 132c of the high pressure, medium pressure, and low pressure; a water level control system for controlling the water level of the water refill 133; The amount of makeup water supplied to the cooling tower 134 is a makeup water amount control system that causes the water level of the cold water tower 134 to be a set value; and an internal temperature control system that controls the temperature of the cooling water of the cooling tower 134. These control systems are used to cause fluctuations in the electric load, fluctuations in the steam flow rate into the steam turbine, fluctuations in the residual heat steam flow rate, pressure fluctuations, fluctuations in the internal temperature of the rehydrator, amount of cooling water, and temperature fluctuations at the outlet of the heat recovery heat exchanger. The liquid level fluctuation of the cooling tower is stabilized, and high-efficiency power generation is performed.

另外，作為使用雙循環發電來改善熱源能量的利用效率的第五現有技術，參照第14圖，針對專利文獻5(JP特開2009-221961公報)中記載的雙循環發電系統進行說明。 In addition, the two-cycle power generation system described in the patent document 5 (JP-A-2009-221961) is described with reference to FIG. 14 as a fifth conventional technique for improving the utilization efficiency of the heat source energy by the use of the two-cycle power generation.

第14圖是本公報記載的雙循環發電系統的方塊圖，將與熱源 流體141進行熱交換而蒸發的低沸點工作介質149的蒸汽導入到蒸汽渦輪機144進行發電。將工作介質預熱的預熱器143和蒸發器142A、142B、蒸汽渦輪機144、熱回收器148、凝結器146、介質供液泵147A、147B串聯構成，而形成閉環。本公報的雙循環發電系統，設置有工作介質的蒸發溫度、壓力不同的多級蒸發器142A、142B，使在各級產生的各蒸汽流入到蒸汽渦輪機(混壓渦輪機)144的高壓級、低壓級，來驅動渦輪發電機145。根據這樣的結構，與利用由僅有單級的蒸發器生成的工作介質的蒸汽驅動蒸汽渦輪機的方式相比，提高了熱源流體所保有的熱能的利用效率。 Figure 14 is a block diagram of the dual-cycle power generation system described in this bulletin, which will be related to the heat source. The steam of the low-boiling working medium 149 which is subjected to heat exchange by the fluid 141 is introduced into the steam turbine 144 to generate electricity. The preheater 143 preheating the working medium and the evaporators 142A, 142B, the steam turbine 144, the heat recovery unit 148, the condenser 146, and the medium supply pumps 147A, 147B are formed in series to form a closed loop. The dual-cycle power generation system of the present publication is provided with a multi-stage evaporator 142A, 142B having different evaporation temperatures and pressures of the working medium, so that each steam generated at each stage flows into a high-pressure stage and a low pressure of the steam turbine (mixed-pressure turbine) 144. Stage to drive the turbine generator 145. According to such a configuration, the utilization efficiency of the thermal energy retained by the heat source fluid is improved as compared with the method of driving the steam turbine by steam using a working medium generated by only a single-stage evaporator.

專利文獻1記載的第一現有技術，由於在火葬爐的內部設置有板狀的熱交換器，並且火葬爐本身被鍋爐化，因此，熱交換器置身於高溫中，在可靠性方面存在問題。另外，本公報記載的發電系統中，每隔一定期間就需要對熱交換器進行保養、修理或者更換新品。 In the first prior art described in Patent Document 1, since a plate-shaped heat exchanger is provided inside the cremation furnace, and the cremation furnace itself is boiler-formed, the heat exchanger is placed at a high temperature, and there is a problem in reliability. Further, in the power generation system described in this publication, it is necessary to maintain, repair, or replace a new heat exchanger at regular intervals.

另外，作為在火葬系統中組合了發電系統的情況下特有的問 題，在火葬爐的運轉週期中，即在急速加熱→焚燒→冷卻的各工序中，火葬爐內的溫度大幅變動。另外，由於一般在夜間不進行火葬，因此火葬爐的溫度變為低溫狀態，在利用高溫的水蒸汽驅動蒸汽渦輪機的方式中，若火葬爐變為比規定溫度還低的低溫，就不能發電。 In addition, it is peculiar to the case when the power generation system is combined in the cremation system. In the operation cycle of the cremation furnace, that is, in each of the steps of rapid heating, incineration, and cooling, the temperature in the cremation furnace greatly changes. Further, since cremation is not performed at night, the temperature of the cremation furnace is lowered to a low temperature state, and in the case where the steam turbine is driven by the high-temperature steam, if the cremation furnace becomes a low temperature lower than the predetermined temperature, power generation cannot be performed.

這樣，由於驅動蒸汽渦輪機用的熱能大幅變動，從發電機輸出的電力不穩定，另外，由於在夜間不得不使發電系統停止工作，因此發電系統的運轉狀態極其不穩定，存在構成發電系統的各裝置容易劣化這樣的問題。 As described above, since the heat energy for driving the steam turbine greatly fluctuates, the power output from the generator is unstable, and since the power generation system has to be stopped at night, the operation state of the power generation system is extremely unstable, and each of the power generation systems is configured. The device is susceptible to such problems.

另外，專利文獻2所記載的第二現有技術，雖然記載了在移動式一體型火葬設備中設置供電裝置115，來供給用於運轉焚燒爐111等裝置的電力這樣的內容，但是針對如何進行發電，沒有任何記載。若根據第11圖進行推定，則可認為供電裝置115是使用了液體燃料的發動機式的發電機。換而言之，本公報中針對為改善火葬系統整體的能源效率而再利用從火葬爐排出的排放氣體的熱能的技術構思的記載或者啟示，沒有任何公開。 In the second prior art described in the patent document 2, it is described that the power supply device 115 is provided in the mobile integrated cremation device to supply electric power for operating the device such as the incinerator 111. There is no record. When the estimation is made based on Fig. 11, it is considered that the power supply device 115 is an engine type generator using liquid fuel. In other words, in this publication, there is no disclosure about the technical idea of reusing the thermal energy of the exhaust gas discharged from the cremation furnace to improve the energy efficiency of the entire cremation system.

而且，專利文獻3記載的第三現有技術，是使沸點為40℃左右的低沸點的工作介質與30℃~80℃左右的熱水進行熱交換而生成工作介質的蒸汽，通過將該工作介質的蒸汽提供給渦輪機123而進行發電。另外，在該現有技術中，為了防止在緊接著工作介質的循環之後，熱水溫度或介質溫度不穩定而使得控制變得不穩定，從工作介質的循環開始起直到經過一定時間為止，將加熱度的目標值設定成低於原來的目標值，來控制液態的工作介質的流量的增減。 Further, in the third prior art described in Patent Document 3, a working medium having a low boiling point boiling point of about 40 ° C and heat of about 30 ° C to 80 ° C is exchanged to generate steam of a working medium, and the working medium is produced. The steam is supplied to the turbine 123 for power generation. Further, in the prior art, in order to prevent the control of the hot water temperature or the medium temperature from becoming unstable after the circulation of the working medium, the heating becomes unstable from the start of the circulation of the working medium until a certain period of time elapses. The target value of the degree is set lower than the original target value to control the increase or decrease of the flow rate of the liquid working medium.

但是基於第三現有技術的餘熱發電裝置，作為餘熱源而設定 了工廠餘熱、溫泉水(地熱)、太陽光等相對穩定的餘熱源，並沒有設定像從火葬爐排出的排放氣體這樣的在短時間內大量熱量變化的餘熱源。因此，餘熱源的熱量穩定，在由發電機產生的電力與消耗該電力的各裝置的總的消耗電力之間獲得平衡的情況下，作為本現有技術的關鍵點的以加熱度為基準的回饋控制是有效的，但是在火葬系統中組合了本公報的餘熱發電裝置並運轉了火葬系統的情況下，由於來自餘熱源的熱量大幅變動，因此產生了在關注於加熱度的控制中並不能使火葬系統整體穩定的運轉這樣的問題。 However, the waste heat power generation device based on the third prior art is set as a residual heat source. A relatively stable waste heat source such as factory waste heat, hot spring water (geothermal heat), and sunlight is not provided, and a waste heat source such as a large amount of heat change in a short period of time such as exhaust gas discharged from a cremation furnace is not set. Therefore, the heat of the residual heat source is stabilized, and in the case where a balance is obtained between the electric power generated by the generator and the total power consumption of each device that consumes the electric power, the feedback based on the heating degree is a key point of the prior art. Control is effective. However, in the case where the waste heat power generation device of this publication is combined and the cremation system is operated in the cremation system, since the heat from the waste heat source greatly fluctuates, it is not possible to control the degree of heating. The problem of the overall stable operation of the cremation system.

下面進行更具體的說明。在火葬的初始階段(~約10分鐘)、中期階段(約10分鐘~約25分鐘)、後期階段(約25分鐘~)，燃燒的物件物、產生的熱量、排放氣體流量、火葬爐的溫度等大幅變動，在火葬系統中組合了發電系統的情況下，必須考慮到這些因素進行設計。另一方面，在基於第三現有技術的餘熱發電裝置中，針對與這些因素對應的控制方法沒有任何記載，在火葬系統中組合了基於第三現有技術的餘熱發電裝置的情況下，存在使用來自餘熱發電裝置的電力不能使火葬系統穩定的運轉這樣的問題。 A more specific explanation will be given below. In the initial stage of cremation (~about 10 minutes), in the middle stage (about 10 minutes to about 25 minutes), in the later stage (about 25 minutes~), burning objects, heat generated, exhaust gas flow, temperature of the cremation furnace If the power generation system is combined in the cremation system, it must be designed in consideration of these factors. On the other hand, in the waste heat power generation apparatus based on the third prior art, there is no description about the control method corresponding to these factors, and in the case where the waste heat power generation apparatus based on the third prior art is combined in the cremation system, there is use from The power of the waste heat power generation device cannot cause the cremation system to operate stably.

另外，專利文獻4記載的第四現有技術，在來自工業用機械設備等的餘熱流量或者餘熱溫度變化的情況下，驅使蒸汽流量控制系統、蒸汽壓力控制系統、熱水液位控制系統等各種各樣的控制系統而得到總是穩定的發電機輸出，但是工作介質是水，若排放氣體溫度為低溫，則實質上不能發電，作為火葬系統用途的發電系統是不適合的。 Further, in the fourth prior art described in Patent Document 4, when the residual heat flow rate or the residual heat temperature from the industrial machine equipment or the like is changed, the steam flow rate control system, the steam pressure control system, the hot water level control system, and the like are driven. The control system obtains an always stable generator output, but the working medium is water. If the exhaust gas temperature is low, the power generation is substantially impossible, and the power generation system used as a cremation system is not suitable.

而且，在來自工業用機械設備等的餘熱流量或者餘熱溫度相 對長時間穩定的情況下，基於該第四現有技術的各種控制系統是有效的，但是因為如上所述那樣在火葬系統中餘熱流量或者餘熱溫度在短時間內大幅變動，因此基於第四現有技術的各種控制系統不能有效發揮功能，存在使用來自發電機的電力不能使火葬系統穩定的運轉這樣的問題。 Moreover, in the waste heat flow or waste heat temperature phase from industrial machinery and the like In the case of long-term stability, various control systems based on the fourth prior art are effective, but since the residual heat flow or the residual heat temperature greatly changes in a short time in the cremation system as described above, based on the fourth prior art The various control systems do not function effectively, and there is a problem that the power from the generator cannot be used to stabilize the cremation system.

另外，專利文獻5記載的雙循環發電系統，是使低沸點工作介質(碳氫化合物、氨等)蒸汽化來驅動蒸汽渦輪機進行發電的雙循環發電系統，作為雙循環發電的特徵，從低溫的熱源也通過熱交換進行發電，另一方面，使用混壓渦輪機效率良好的進行發電。但是，作為熱源，設定了比較穩定的地熱流體(熱水或者蒸汽)、工廠設備的熱排水，在像火葬系統那樣的餘熱流量或者餘熱溫度在短時間內大幅變動的系統中組合了基於該現有技術的雙循環發電系統時，存在如下問題：在變動小的情況下，能夠發揮功能，但是在變動大的情況下，僅基於混壓渦輪機進行控制，火葬系統不能進行穩定的運轉。 Further, the dual-cycle power generation system described in Patent Document 5 is a dual-cycle power generation system that vaporizes a low-boiling working medium (hydrocarbon, ammonia, etc.) to drive a steam turbine to generate electricity, and is characterized by double-cycle power generation from a low temperature. The heat source also generates electricity by heat exchange, and on the other hand, the mixed-pressure turbine is used to efficiently generate electricity. However, as a heat source, a relatively stable geothermal fluid (hot water or steam) and hot water drainage of factory equipment are set, and a system in which a residual heat flow rate or a residual heat temperature such as a cremation system greatly fluctuates in a short period of time is combined based on the existing In the technical dual-cycle power generation system, there is a problem that the function can be performed when the fluctuation is small, but when the fluctuation is large, the control is performed only by the mixed-pressure turbine, and the cremation system cannot perform stable operation.

Switching from the external power source to the backup power source.

本發明的火葬系統，使用雙循環發電方式，即，從火葬爐排出的排放氣體通過熱交換器，由此，將排放氣體的熱能轉換為熱水的熱能，進一步，該熱水經由緩衝罐而通過蒸發器，使低沸點工作介質蒸汽化，通過產生的工作介質的蒸汽，驅動蒸汽渦輪機進行發電。而通過將發電的電力供給到構成火葬系統的各裝置，能夠大幅減少火葬系統的消耗電力。 The cremation system of the present invention uses a two-cycle power generation method in which exhaust gas discharged from a cremation furnace passes through a heat exchanger, thereby converting heat energy of the exhaust gas into heat energy of the hot water, and further, the hot water is passed through the buffer tank The low boiling working medium is vaporized by an evaporator, and the steam of the working medium is generated to drive the steam turbine to generate electricity. By supplying the generated electric power to each device constituting the cremation system, the power consumption of the cremation system can be greatly reduced.

另外，從火葬爐排出的排放氣體具有在短時間內熱量大幅變化這樣的特徵，但是本發明的火葬系統能夠穩定的發電，並且，從外部電源或者備用電源供給火葬系統所需要的不足部分的電力，從而能夠使火葬系統穩定的運轉。 Further, the exhaust gas discharged from the cremation furnace has a characteristic that the heat is largely changed in a short time, but the cremation system of the present invention can stably generate electricity, and the insufficient power required for the cremation system is supplied from an external power source or a backup power source. Therefore, the cremation system can be stably operated.

另外，由於來自火葬爐的餘熱流量、餘熱溫度、溫度上升率等資訊能夠預先預測，因此使用該預測資訊，能夠效率良好且穩定的控制發電系統。 Further, since information such as the residual heat flow rate, the residual heat temperature, and the temperature increase rate from the cremation furnace can be predicted in advance, the power generation system can be controlled efficiently and stably using the prediction information.

進一步，作為本發明的發電系統，由於使用了使低沸點介質蒸汽化來驅動介質渦輪機的雙循環發電方式，因此即使是在從火葬爐排出的排放氣體溫度低下的情況下也能夠發電，能夠使每一天的發電期間變長。因此，能够提高發電效率。 Further, as the power generation system of the present invention, since the double-cycle power generation method of driving the medium turbine by vaporizing the low-boiling medium is used, power generation can be performed even when the temperature of the exhaust gas discharged from the cremation furnace is lowered. The power generation period of each day becomes longer. Therefore, power generation efficiency can be improved.

另外，由於控制流入蒸發器的熱水的熱量，使得來自排放氣體/熱水熱交換器的熱水的溫度不超過設定值，因此確保了蒸發器的安全性，即使是面對火葬系統所特有的問題、即熱水大幅的變動，也能夠使雙循環發電穩定的運轉。 In addition, since the heat of the hot water flowing into the evaporator is controlled so that the temperature of the hot water from the exhaust gas/hot water heat exchanger does not exceed the set value, the safety of the evaporator is ensured, even if it is unique to the cremation system. The problem, that is, the large change in hot water, also enables stable operation of dual-cycle power generation.

進一步，進行控制，使得當來自排放氣體/熱水熱交換器的熱水的溫度達到指定的規定值時，從注水裝置將冷卻水注入到流入蒸發器的熱水中，使熱水的溫度下降。因此，即使是在因火葬爐的異常燃燒等使得排放氣體溫度異常高的情況下，雙循環發電系統也不會緊急停止，即使是面對熱水大幅的變動，也能夠使雙循環發電穩定的運轉。 Further, control is performed such that when the temperature of the hot water from the exhaust gas/hot water heat exchanger reaches a prescribed prescribed value, the cooling water is injected from the water injection device into the hot water flowing into the evaporator to lower the temperature of the hot water . Therefore, even in the case where the temperature of the exhaust gas is abnormally high due to abnormal combustion of the cremation furnace, the dual-cycle power generation system does not stop urgently, and even in the face of a large fluctuation of the hot water, the double-cycle power generation can be stabilized. Running.

另外，由於來自排放氣體/熱水熱交換器的高溫的熱水首先流入第一緩衝罐，與第一緩衝罐內的熱水溫度平均化之後，該熱水被供給到蒸發器，因此即使是排放氣體的餘熱量大幅變化，也能夠穩定的發電。 In addition, since the hot water from the high temperature of the exhaust gas/hot water heat exchanger first flows into the first buffer tank, after the temperature of the hot water in the first buffer tank is averaged, the hot water is supplied to the evaporator, so even The residual heat of the exhaust gas changes drastically, and stable power generation is also possible.

另外，由於來自蒸發器的熱水流入不同於第一緩衝罐的第二緩衝罐，與第二緩衝罐內的熱水溫度平均化之後，該熱水返回到排放氣體/熱水熱交換器，因此排放氣體/熱水熱交換器內的熱水溫度不會過於上升。所以，排放氣體/熱水熱交換器的可靠性高，並且，具有如下這樣的特徵：由於來自排放氣體/熱水熱交換器的熱水溫度的變動更小，因此通過穩定的運轉，能夠進行效率良好的發電。 In addition, since the hot water from the evaporator flows into the second buffer tank different from the first buffer tank, and after the temperature of the hot water in the second buffer tank is averaged, the hot water is returned to the exhaust gas/hot water heat exchanger. Therefore, the temperature of the hot water in the exhaust gas/hot water heat exchanger does not rise too much. Therefore, the exhaust gas/hot water heat exchanger has high reliability, and has a feature that the temperature of the hot water from the exhaust gas/hot water heat exchanger is smaller, so that stable operation can be performed. Efficient power generation.

進一步，由電力資訊處理裝置自動控制各注水閥，使得在上述兩個緩衝罐內設置的溫度計的熱水溫度達到上限設定值時，從注水裝置經由各注水閥向上述兩個緩衝罐注入冷卻水，使緩衝罐內的熱水溫度為上限設定值以下。 Further, the power information processing device automatically controls the water injection valves such that when the hot water temperature of the thermometers provided in the two buffer tanks reaches the upper limit set value, the water injection device injects cooling water into the two buffer tanks via the respective water injection valves. The hot water temperature in the buffer tank is below the upper limit set value.

另外，在第一以及第二緩衝罐分別設置用於測定各熱水的液面液位的液位計，使用來自這些感測器的信號隨時控制熱水循環泵，使得第一以及第二緩衝罐的液面液位的差幾乎一定。由此，即使是兩個熱水循環泵的噴出量的性能並不完全相同而是非平衡的，也不會產生一個緩衝罐 的熱水殘留量持續增大而另一個緩衝罐的熱水殘留量持續減少這樣的問題，能夠使發電系統穩定的運轉。 In addition, liquid level meters for measuring the liquid level of each hot water are respectively provided in the first and second buffer tanks, and the hot water circulation pump is controlled at any time by using signals from the sensors to make the first and second buffers The difference in the liquid level of the tank is almost constant. Thus, even if the performance of the discharge amounts of the two hot water circulation pumps is not exactly the same but is not balanced, a buffer tank will not be produced. The problem that the amount of remaining hot water continues to increase and the amount of hot water remaining in the other buffer tank continues to decrease can stabilize the operation of the power generation system.

另外，在緩衝罐的下部設置排出閥，進行控制，使得當在緩衝罐內設置的各液位計的測定值達到設定值時打開排出閥，將緩衝罐的熱水自動排出，緩衝罐的熱水不會溢出。進一步，在通過排出閥也不能充分排出熱水的情況下，可經由在各緩衝罐的側面上部設置的溢出噴嘴，將緩衝罐內的熱水排出，實施了雙重的溢出對策。 Further, a discharge valve is provided at a lower portion of the buffer tank, and control is performed such that when the measured value of each liquid level gauge provided in the buffer tank reaches a set value, the discharge valve is opened, and the hot water of the buffer tank is automatically discharged, and the heat of the buffer tank is automatically Water will not overflow. Further, when the hot water cannot be sufficiently discharged by the discharge valve, the hot water in the buffer tank can be discharged through the overflow nozzle provided on the upper portion of the side surface of each of the buffer tanks, and a double overflow countermeasure is implemented.

另外，由於使用了如下的雙循環發電方式，即，使來自火葬爐的排放氣體通過熱交換器，從而將排放氣體的熱能轉換為熱水的熱能，進一步，使該熱水通過蒸發器而使低沸點介質蒸汽化，由所產生的蒸汽驅動介質渦輪機進行發電，因此從含有大量灰塵的火葬爐排出的排放氣體並不直接流入蒸發器，所以，能夠將從含有大量灰塵的火葬爐排出的排放氣體的熱量作為電能有效地回收。 In addition, since the double-cycle power generation method is employed in which the exhaust gas from the cremation furnace is passed through the heat exchanger, the heat energy of the exhaust gas is converted into the heat energy of the hot water, and further, the hot water is passed through the evaporator. The low-boiling medium is vaporized, and the generated steam drives the medium turbine to generate electricity. Therefore, the exhaust gas discharged from the cremation furnace containing a large amount of dust does not directly flow into the evaporator, so that it can be discharged from the cremation furnace containing a large amount of dust. The heat of the gas is efficiently recovered as electrical energy.

接著參考第1圖~第4圖針對本發明的實施方式進行詳細的說明。 Next, an embodiment of the present invention will be described in detail with reference to Figs. 1 to 4 .

<第一實施方式> <First embodiment>

第1圖是本發明第一實施方式的火葬系統的結構圖，第2圖是構成火葬系統的雙循環發電系統19的結構圖，第3圖是用於說明本發明的火葬系統的電力控制動作的方塊圖，第4圖是用於說明主燃爐11的燃燒方法的說明圖。本發明的火葬系統具有：安放棺材17的告別台16；使用主燃燃燒器12進行遺體、陪葬品、棺材等的燃燒的主燃爐11；使來自主燃爐11的排放氣體完全燃燒用的再燃爐13；能夠將棺材17自動送入到主燃爐12中的自動收棺裝置15。 1 is a configuration diagram of a cremation system according to a first embodiment of the present invention, FIG. 2 is a configuration diagram of a double-cycle power generation system 19 constituting a cremation system, and FIG. 3 is a power control operation for explaining a cremation system of the present invention. FIG. 4 is an explanatory diagram for explaining a combustion method of the main burner 11. The cremation system of the present invention includes: a farewell table 16 on which the coffin 17 is placed, a main burner 11 that burns the remains, the funerary objects, the coffin, and the like using the main combustion burner 12; and the exhaust gas from the main combustion furnace 11 is completely burned. The reburning furnace 13 can automatically feed the coffin 17 into the automatic collecting device 15 in the main combustion furnace 12.

另外，從主燃爐11排出的排放氣體通過與再燃爐13連通的共通煙道18A以及排氣通道18B，被導入到雙循環發電系統19。另外，設置有排放氣體輔助冷卻裝置兼緊急排氣通道18C，用於冷卻從共通煙道18A排出的排放氣體，並且為在火葬系統產生異常燃燒的情況下所準備。被導入到構成雙循環發電系統19的第2圖所記載的排放氣體/熱水熱交換器21的排放氣體，與在排放氣體/熱水熱交換器21內的管道的外側流動的冷媒(水)進行熱交換而傳遞熱能，進一步流入到熱風回收熱交換器110。所流入的排放氣體與空氣進行熱交換，因排放氣體而變熱的熱風經由熱風回收路徑116被導入到主燃爐11。由此，能夠提高主燃爐11的燃燒效率，並且實現燃料的節減和燃燒時間的縮短。另外，排放氣體從排放氣體/熱水熱交換器21向著第2圖的朝上箭頭方向排出，流入到第1圖的熱風回收熱交換器110。另外，冷媒不限於水，只要是與排放氣體進行熱交換的介質即可。 Further, the exhaust gas discharged from the main combustion furnace 11 is introduced into the dual-cycle power generation system 19 through the common flue 18A and the exhaust passage 18B that communicate with the reburning furnace 13. Further, an exhaust gas auxiliary cooling device and an emergency exhaust passage 18C are provided for cooling the exhaust gas discharged from the common flue 18A, and are prepared in the case where abnormal combustion occurs in the cremation system. The exhaust gas introduced into the exhaust gas/hot water heat exchanger 21 described in Fig. 2 of the dual cycle power generation system 19 and the refrigerant flowing outside the pipe in the exhaust gas/hot water heat exchanger 21 (water) The heat exchange is performed to transfer the heat energy, and further flows into the hot air recovery heat exchanger 110. The inflowing exhaust gas exchanges heat with the air, and the hot air which is heated by the exhaust gas is introduced into the main combustion furnace 11 via the hot air collecting path 116. Thereby, the combustion efficiency of the main combustion furnace 11 can be improved, and the fuel reduction and the combustion time can be shortened. In addition, the exhaust gas is discharged from the exhaust gas/hot water heat exchanger 21 in the direction of the upward arrow of FIG. 2, and flows into the hot air recovery heat exchanger 110 of Fig. 1 . Further, the refrigerant is not limited to water, and may be any medium that exchanges heat with the exhaust gas.

從熱風回收熱交換器110流出的排放氣體，由於排放氣體的溫度下降，與從吸氣口111進入的外氣一起流入到電集塵裝置112中，在此將排放氣體中所包含的灰塵除去。接著從電集塵裝置112流出的排放氣體被送到催化裝置113，在此將排放氣體中所包含的氮氧化物、臭氣成分、多氯二苯二惡英和多氯二苯呋喃等的二惡英類除去。從催化裝置113流出的排放氣體被排風機114吸引而經由排氣筒115排放到大氣中。 The exhaust gas flowing out of the hot air recovery heat exchanger 110 flows into the electric dust collecting device 112 together with the external air entering from the air intake port 111 due to the temperature drop of the exhaust gas, where the dust contained in the exhaust gas is removed. . Then, the exhaust gas flowing out from the electric dust collecting device 112 is sent to the catalytic device 113, where the nitrogen oxides, odor components, polychlorinated dibenzodioxins, and polychlorinated dibenzofurans contained in the exhaust gas are included. The evil class is removed. The exhaust gas flowing out of the catalytic device 113 is attracted by the exhaust fan 114 and discharged to the atmosphere via the exhaust cylinder 115.

這樣，本發明的火葬系統，將在主燃爐11產生的大量的灰塵以及二惡英等有害物質除去，再生成清潔的空氣，並返還到大氣中，並且，使用雙循環發電系統，利用排放氣體所具有的高溫的熱能進行發電，將所發電的電力供給到構成火葬系統的各裝置，由此，能夠供應各裝置所需要 的部分或者全部電力，能夠將火葬系統整體的節能化大幅提高。 Thus, the cremation system of the present invention removes a large amount of dust generated in the main burner 11 and harmful substances such as dioxin, generates clean air, returns it to the atmosphere, and uses a dual-cycle power generation system to utilize the discharge. The high-temperature thermal energy of the gas generates electricity, and the generated electric power is supplied to each device constituting the cremation system, thereby being able to supply each device. Part or all of the power can greatly increase the energy saving of the entire cremation system.

如前所述那樣，從火葬爐排出的排放氣體的溫度、餘熱量以及排放氣體的流量在火葬時變化很大，這是在構築以進一步節能化為目標的下一代火葬系統時極其重要的關鍵點。接著參考第4圖，針對火葬爐的燃燒方法具體說明。 As mentioned above, the temperature of the exhaust gas discharged from the cremation furnace, the amount of residual heat, and the flow rate of the exhaust gas vary greatly during cremation, which is an extremely important key in constructing the next-generation cremation system aimed at further energy saving. point. Next, referring to Fig. 4, the combustion method of the cremation furnace will be specifically described.

火葬方法在大的方面被分為四個階段，按照初始階段、中期階段、後期階段、結束階段的順序進行，從火葬開始起直至收集骨灰為止需要大約1小時，該週期在一天中一個爐反復進行1~7次。在初始階段(燃燒開始~約10分鐘)，使主燃燃燒器12的火焰最大來促進著火，並且多多供給從主燃爐11的側壁供給的二次空氣、三次空氣，主要是使棺材燃燒。通過這樣的燃燒方法，與遺體相比，棺材急劇燃燒。因此，排放氣體的溫度急速上升，另外，一時產生大量的排放氣體。 The cremation method is divided into four stages in a large aspect, in the order of the initial stage, the intermediate stage, the late stage, and the end stage. It takes about one hour from the start of the cremation to the collection of the ashes, which is repeated in one furnace in the day. Perform 1~7 times. In the initial stage (starting of combustion - about 10 minutes), the flame of the main combustion burner 12 is maximized to promote ignition, and a large amount of secondary air and tertiary air supplied from the side wall of the main combustion furnace 11 are supplied, mainly to burn the coffin. By such a combustion method, the coffin is rapidly burned compared to the remains. Therefore, the temperature of the exhaust gas rises rapidly, and in addition, a large amount of exhaust gas is generated at one time.

接著在中期階段，燃燒的物件從棺材變為遺體以及陪葬品，根據遺體脂肪的多少，燃燒的方式以及排放氣體的流量有很大變化。由於在脂肪多的遺體的情況下激烈燃燒，因此進行控制，使得主燃燃燒器12的火焰的大小儘量小，使得來自主燃爐11側壁的二次空氣、三次空氣最大供給，使得自燃燃燒不會失去控制。通過這樣的燃燒方法，脂肪多的遺體的情況下，排放氣體的流量變大，另一方面，脂肪少的遺體的情況下，與脂肪多的遺體的情況相比，燃燒弱，排放氣體的流量與脂肪多的遺體燃燒的情況相比，根據經驗可知，大概為一半以下。 Then in the mid-stage, the burning objects changed from coffin to remains and funerary objects, depending on how much fat the body has, how it burns, and how much the flow of exhaust gas changes. Since the combustion is intense in the case of a body having a large amount of fat, control is performed such that the size of the flame of the main combustion burner 12 is as small as possible, so that the secondary air and the tertiary air from the side wall of the main combustion furnace 11 are supplied at the maximum, so that the spontaneous combustion does not occur. Will lose control. According to such a combustion method, in the case of a body having a large amount of fat, the flow rate of the exhaust gas is increased. On the other hand, in the case of a body having a small amount of fat, the combustion is weak and the flow rate of the exhaust gas is lower than in the case of a body having a large amount of fat. Compared with the case where the fat body is burned, it is known that it is about half or less.

接著在後期階段，使殘留在遺骨周圍的部分遺體燃燒，但若主燃燃燒器12的火焰過強，則遺骨粉碎，使得收集骨灰變得困難，因此進 行控制，使得火焰與來自主燃爐11側壁的二次空氣和三次空氣的供給都變小。通過這樣的燃燒方法，排放氣體的流量減少到峰值時的大約1/2~1/3。 Then, in the later stage, part of the remains remaining around the remains are burned, but if the flame of the main burner 12 is too strong, the bones are crushed, making it difficult to collect the ashes, so The line control makes the supply of the flame and the secondary air and the tertiary air from the side wall of the main burner 11 small. By such a combustion method, the flow rate of the exhaust gas is reduced to about 1/2 to 1/3 of the peak value.

接著在結束階段，對主燃爐11進行空氣冷卻，將骨接收盤(圖中未示)上的遺骨拉出到前室14，進而拉出到告別台16，進行骨灰的收集。這時，排放氣體的流量低至0的水平。一個火葬爐按順序反復上述的四個階段來進行作業，但是在實際上的火葬系統中，一般是兩個~四個火葬爐作為一個系統而構成為一體。即，兩個~四個主燃爐11、再燃爐13、共通煙道18A、排氣通道18B、排放氣體輔助冷卻裝置兼緊急排氣通道18C分別獨立設置，從兩個~四個排氣通道18B排出的排放氣體，都流入到共同的具有排放氣體/熱水熱交換器的雙循環發電系統19中。 Next, at the end stage, the main burner 11 is air-cooled, and the bones on the bone receiving tray (not shown) are pulled out to the front chamber 14, and then pulled out to the farewell station 16, and the ashes are collected. At this time, the flow rate of the exhaust gas is as low as zero. A cremation furnace repeats the above four stages in order to carry out the work, but in the actual cremation system, generally two to four cremation furnaces are integrated as one system. That is, two to four main burners 11, a reburning furnace 13, a common flue 18A, an exhaust passage 18B, an exhaust gas auxiliary cooling device, and an emergency exhaust passage 18C are independently provided, from two to four exhaust passages. The exhaust gas discharged from 18B flows into a common dual-cycle power generation system 19 having an exhaust gas/hot water heat exchanger.

雖然各火葬爐的火葬開始時刻各不相同，各火葬爐的火葬階段(初始階段~結束階段)也不同，但是一個系統的各火葬爐可分別同時進行火葬。因此，在各火葬爐的火葬開始時刻重合的情況下，流入到雙循環發電系統19的排放氣體的熱量與一個火葬爐的情況相比，以數倍的大小進行變動。若有意識的使火葬開始時刻錯開，則能夠抑制流入到雙循環發電系統19的排放氣體的熱量的變動，但是實際上有意識的錯開火葬開始時刻是困難的。因此，在本發明的火葬系統中，也可以是把握各火葬爐處於火葬階段的哪個階段(初始階段~結束階段)，並且電力資訊處理裝置211B使用該資訊，控制雙循環發電系統19穩定且有效的發電。 Although the cremation start time of each cremation furnace is different, the cremation stage (initial stage to the end stage) of each cremation furnace is different, but each system of cremation furnaces can be simultaneously cremation. Therefore, when the cremation start timing of each cremation furnace coincides, the amount of heat of the exhaust gas flowing into the two-cycle power generation system 19 fluctuates several times as compared with the case of one cremation furnace. If the cremation start timing is consciously shifted, the fluctuation of the heat of the exhaust gas flowing into the two-cycle power generation system 19 can be suppressed, but it is actually difficult to consciously shift the start of the cremation. Therefore, in the cremation system of the present invention, it is also possible to grasp which stage (initial stage to end stage) each cremation furnace is in the cremation stage, and the power information processing apparatus 211B uses the information to control the two-cycle power generation system 19 to be stable and effective. Power generation.

另外，為了簡單的進行說明，上述內容中將火葬分為四個階段進行了說明，但是實際上細分為更多的階段進行控制。另外，也可以構成為：設置有測定主燃爐11、再燃爐13的溫度用的溫度計、測定壓力用的 壓力計、測定氧濃度用的氧濃度計、測定排煙濃度用的排煙濃度計，電力資訊處理裝置211B使用來自這些感測器的資訊，控制雙循環發電系統19穩定且有效的發電。 In addition, for the sake of simplicity, the above description has been described in which the cremation is divided into four stages, but actually it is subdivided into more stages for control. Further, a thermometer for measuring the temperature of the main burner 11 and the reburning furnace 13 may be provided, and a pressure for measuring the pressure may be provided. The pressure meter, the oxygen concentration meter for measuring the oxygen concentration, and the smoke concentration meter for measuring the smoke exhaust concentration, the power information processing device 211B uses the information from these sensors to control the stable and efficient power generation of the dual cycle power generation system 19.

接著參考第2圖，針對雙循環發電系統19進行詳細說明。來自排氣通道18B的排放氣體在排放氣體/熱水熱交換器21與冷媒(水)進行熱交換而使冷媒熱水化。在排放氣體/熱水熱交換器21生成的熱水，從緩衝罐215A的上方向緩衝罐215A內注水，進一步從緩衝罐215A的下方被熱水循環泵22A吸引，經由流量調整閥212B向蒸發器23送出(噴出)。 Next, the dual cycle power generation system 19 will be described in detail with reference to FIG. The exhaust gas from the exhaust passage 18B exchanges heat with the refrigerant (water) in the exhaust gas/hot water heat exchanger 21 to heat the refrigerant. The hot water generated in the exhaust gas/hot water heat exchanger 21 is filled with water from the upper side of the buffer tank 215A toward the buffer tank 215A, and is further sucked from the lower side of the buffer tank 215A by the hot water circulation pump 22A, and is evaporated by the flow rate adjustment valve 212B. The device 23 sends (spurts out).

從蒸發器23流出的熱水，從緩衝罐215B的上方向緩衝罐215B內注水，進一步從緩衝罐215B的下方被熱水循環泵22D吸引，向排放氣體/熱水熱交換器21送出(噴出)。這樣，熱水在排放氣體/熱水熱交換器21→緩衝罐215A→熱水循環泵22A→流量調整閥212B→蒸發器23→緩衝罐215B→熱水循環泵22D→排放氣體/熱水熱交換器21的路徑上循環。 The hot water that has flowed out of the evaporator 23 is filled with water from the buffer tank 215B from the upper side of the buffer tank 215B, and is sucked by the hot water circulation pump 22D from below the buffer tank 215B, and sent to the exhaust gas/hot water heat exchanger 21 (discharge). ). Thus, the hot water is in the exhaust gas/hot water heat exchanger 21 → the buffer tank 215A → the hot water circulation pump 22A → the flow rate adjustment valve 212B → the evaporator 23 → the buffer tank 215B → the hot water circulation pump 22D → the exhaust gas/hot water heat Loop on the path of the switch 21.

在蒸發器23，氨、碳氫化合物、異丁烷等低沸點工作介質與熱水之間進行熱交換，工作介質被加熱，從而工作介質蒸汽化。在蒸發器23生成的工作介質的蒸汽，被送到介質渦輪機24而驅動介質渦輪機24。進而通過介質渦輪機24的驅動軸旋轉，與驅動軸連接著的發電機的驅動軸旋轉，發電機25進行發電。另外，在第2圖中，示出了介質渦輪機24與發電機25作為獨立的裝置構成的情況，但是介質渦輪機24與發電機25同軸一體構成也可以。通過這樣的結構，能夠實現雙循環發電系統的小型化。 In the evaporator 23, heat exchange is performed between a low boiling working medium such as ammonia, hydrocarbon, isobutane and hot water, and the working medium is heated to vaporize the working medium. The steam of the working medium generated at the evaporator 23 is sent to the medium turbine 24 to drive the medium turbine 24. Further, by the rotation of the drive shaft of the medium turbine 24, the drive shaft of the generator connected to the drive shaft rotates, and the generator 25 generates electric power. Further, in the second drawing, the case where the medium turbine 24 and the generator 25 are configured as separate devices is shown, but the medium turbine 24 may be integrally formed coaxially with the generator 25. With such a configuration, it is possible to achieve downsizing of the dual-cycle power generation system.

在發電機25產生的交流電力，在高頻整流器26被轉換為直流，進而在DC/AC變頻器被轉換為50Hz或者60Hz等商用電力，被輸出到 電力輸出終端28。另外，在發電機25的輸出側設置逆變器，通過該逆變器，對發電機25施加制動，一邊控制發電機25的轉速一邊進行控制以使發電效率最大化。 The AC power generated by the generator 25 is converted into a direct current at the high frequency rectifier 26, and is converted into commercial power such as 50 Hz or 60 Hz in the DC/AC inverter, and is output to Power output terminal 28. Further, an inverter is provided on the output side of the generator 25, and braking is applied to the generator 25 by the inverter, and control is performed while controlling the number of revolutions of the generator 25 to maximize power generation efficiency.

另一方面，來自介質渦輪機24的工作介質的蒸汽流入到凝結器29，在此，工作介質的蒸汽與冷卻水之間進行熱交換，工作介質的蒸汽凝結而液化。冷卻水通過冷卻水循環泵22C而在凝結器29與冷卻塔210之間循環。在凝結器29溫度上升的冷卻水在冷卻塔210被冷卻，返回到凝結器29，重複該週期，在凝結器29與工作介質的蒸汽之間的熱交換穩定且持續。這時，冷卻水循環泵22C接收來自電力資訊處理裝置211B的控制信號，控制冷卻水的流量。即，電力資訊處理裝置211B根據來自在凝結器29設置的溫度感測器以及壓力感測器的信號進行控制，以使發電穩定而效率最大化。 On the other hand, the steam from the working medium of the medium turbine 24 flows into the condenser 29, where heat exchange is performed between the steam of the working medium and the cooling water, and the vapor of the working medium is condensed and liquefied. The cooling water circulates between the condenser 29 and the cooling tower 210 through the cooling water circulation pump 22C. The cooling water whose temperature rises in the condenser 29 is cooled in the cooling tower 210, returns to the condenser 29, and the cycle is repeated, and the heat exchange between the condenser 29 and the steam of the working medium is stabilized and continued. At this time, the cooling water circulation pump 22C receives a control signal from the power information processing device 211B to control the flow rate of the cooling water. That is, the power information processing device 211B performs control based on signals from the temperature sensor and the pressure sensor provided at the condenser 29 to stabilize power generation and maximize efficiency.

從凝結器29流出的工作介質被工作介質泵22B吸入，向蒸發器23送出，再次與熱水進行熱交換而蒸汽化。重複這樣的週期，雙循環發電持續進行。另外，電力資訊處理裝置211B根據來自在凝結器29設置的溫度感測器以及壓力感測器的信號，使用工作介質泵22B控制工作介質的流量，從而進行控制以使發電機25的輸出電力穩定且效率最大化。 The working medium flowing out of the condenser 29 is sucked by the working medium pump 22B, sent to the evaporator 23, and again subjected to heat exchange with hot water to be vaporized. Repeating such a cycle, the two-cycle power generation continues. Further, the power information processing device 211B controls the flow rate of the working medium using the working medium pump 22B based on the signals from the temperature sensor and the pressure sensor provided at the condenser 29, thereby performing control to stabilize the output power of the generator 25. And maximize efficiency.

從排放氣體/熱水熱交換器21被送出到蒸發器23的熱水的溫度，一般是根據被送出到排放氣體/熱水熱交換器21的排放氣體溫度以及熱量等而變化，因此伴隨著被送出到排放氣體/熱水熱交換器21的排放氣體的溫度以及熱量等的變化，熱水的溫度大幅變化。因此，當流入蒸發器23的熱水的溫度超過允許值時，雙循環發電系統的運轉會變得不穩定，最壞的情況下，有可能使得工作介質的蒸汽的壓力極端高而使得蒸發器23 等損壞。 The temperature of the hot water sent to the evaporator 23 from the exhaust gas/hot water heat exchanger 21 is generally changed according to the temperature of the exhaust gas sent to the exhaust gas/hot water heat exchanger 21, heat, and the like, and thus The temperature of the exhaust gas sent to the exhaust gas/hot water heat exchanger 21, and the change in heat, etc., greatly change the temperature of the hot water. Therefore, when the temperature of the hot water flowing into the evaporator 23 exceeds the allowable value, the operation of the dual-cycle power generation system becomes unstable, and in the worst case, it is possible to make the pressure of the steam of the working medium extremely high and cause the evaporator twenty three And so on.

作為防止對策，本發明的火葬系統中，設置有兩個系統的緩衝罐215A、215B，流入該緩衝罐215A、215B的熱水的溫度與緩衝罐215A、215B內的熱水溫度平均化，使得流入的熱水的溫度變動大幅降低。参考第2圖進行具體說明。在排放氣體/熱水熱交換器21與熱水循環泵22A之間設置緩衝罐215A，在蒸發器23與熱水循環泵22D之間設置緩衝罐215B。在各緩衝罐215A、215B中分別設置液位計216A、216B，用於測定緩衝罐215A、215B內的熱水的殘留量，換而言之，用於測定熱水的液面高度，另外，分別設置用於測定緩衝罐215A、215B內的熱水溫度的溫度計217A、217B。來自溫度計217A、217B的溫度信號被輸出到電力資訊處理裝置211B，但在第2圖中省略了該信號線。另外，針對溫度計217C、217D，也同樣省略了信號線。 As a countermeasure against the problem, in the cremation system of the present invention, buffer tanks 215A and 215B of two systems are provided, and the temperature of the hot water flowing into the buffer tanks 215A and 215B and the temperature of the hot water in the buffer tanks 215A and 215B are averaged. The temperature fluctuation of the inflowing hot water is greatly reduced. The details will be described with reference to FIG. A buffer tank 215A is provided between the exhaust gas/hot water heat exchanger 21 and the hot water circulation pump 22A, and a buffer tank 215B is provided between the evaporator 23 and the hot water circulation pump 22D. Liquid level meters 216A and 216B are provided in each of the buffer tanks 215A and 215B, and are used to measure the residual amount of hot water in the buffer tanks 215A and 215B, in other words, to measure the liquid level of the hot water, and Thermometers 217A, 217B for measuring the temperature of the hot water in the buffer tanks 215A, 215B are provided separately. The temperature signals from the thermometers 217A, 217B are output to the power information processing device 211B, but the signal lines are omitted in Fig. 2. Further, the signal lines are also omitted for the thermometers 217C and 217D.

來自排放氣體/熱水熱交換器21的熱水，從緩衝罐215A的上方注入，從緩衝罐215A的下方通過熱水循環泵22A而被供給到蒸發器23。另一方面，來自蒸發器23的熱水從緩衝罐215B的上方注入，從緩衝罐215B的下方通過熱水循環泵22D被供給到排放氣體/熱水熱交換器21。這時，電力資訊處理裝置211B，根據來自液位計216A、216B的測定信號，隨時監視緩衝罐215A、215B內的熱水殘留量，即熱水的液面高度，並且通過熱水循環泵22A、22D分別動態的控制相對於平均流速的變化量，以使得這些熱水殘留量相等。即，若將緩衝罐215A、215B內的熱水的液面高度分別設為H1、H2，則通過熱水循環泵22A、22D動態的控制單位時間內熱水的流量、即流速，以使得H1=H2。 The hot water from the exhaust gas/hot water heat exchanger 21 is injected from above the buffer tank 215A, and is supplied to the evaporator 23 from below the buffer tank 215A through the hot water circulation pump 22A. On the other hand, the hot water from the evaporator 23 is injected from above the buffer tank 215B, and is supplied from the lower side of the buffer tank 215B to the exhaust gas/hot water heat exchanger 21 through the hot water circulation pump 22D. At this time, the power information processing device 211B monitors the remaining amount of hot water in the buffer tanks 215A and 215B, that is, the liquid level of the hot water, and passes through the hot water circulation pump 22A, based on the measurement signals from the level gauges 216A and 216B. 22D dynamically controls the amount of change with respect to the average flow rate, respectively, so that these hot water residual amounts are equal. In other words, when the liquid level heights of the hot water in the buffer tanks 215A and 215B are respectively H1 and H2, the hot water circulation pumps 22A and 22D dynamically control the flow rate of the hot water per unit time, that is, the flow rate, so that H1 is made. =H2.

具體而言，在H1>H2的情況下，提高熱水循環泵22A的轉速，增大從緩衝罐215A流出的流出量，另一方面，降低熱水循環泵22B的轉速，減少從緩衝罐215B流出的流出量。另外，在H1<H2的情況下，進行與上述情況相反的控制。通過這樣的控制，能夠防止如下這樣的問題，即，在熱水循環泵22A、22B的性能並不完全相同而打破平衡的情況下，兩個熱水循環泵22A、22B的噴出量不同，一個緩衝罐的熱水殘留量持續增大，最終熱水從緩衝罐溢出，另一個緩衝罐的熱水殘留量持續減少，緩衝罐的熱水殘留量變為空的。另外，在上述的說明中，針對進行控制以使得H1=H2的情況進行了說明，但是也不必一定這樣限定控制，若進行控制以使得△H=| H1-H2 |為一定值，也能得到同樣的效果。 Specifically, when H1>H2, the number of revolutions of the hot water circulation pump 22A is increased, and the amount of outflow from the buffer tank 215A is increased. On the other hand, the number of revolutions of the hot water circulation pump 22B is lowered, and the buffer tank 215B is reduced. The outflow of the outflow. Further, in the case of H1 < H2, the control opposite to the above case is performed. By such control, it is possible to prevent a problem that the discharge amounts of the two hot water circulation pumps 22A and 22B are different when the performances of the hot water circulation pumps 22A and 22B are not completely the same and the balance is broken. The residual amount of hot water in the buffer tank continues to increase, and finally the hot water overflows from the buffer tank, and the residual amount of hot water in the other buffer tank continues to decrease, and the residual amount of hot water in the buffer tank becomes empty. Further, in the above description, the case where control is performed such that H1 = H2 has been described, but it is not necessary to limit the control as such, and if control is performed such that ΔH = | H1 - H2 | is a certain value, it is also possible to obtain The same effect.

另外，在緩衝罐215A、215B的下部設置排出閥(未圖示)，進行自動控制，以使得當在緩衝罐內設置的液位計216A、216B的測定值達到設定值時，排出閥打開，將緩衝罐216A、216B的熱水排出，從而緩衝罐216A、216B的熱水不會溢出。進一步，在即使通過排出閥，熱水的排出也不充分的情況下，通過在各緩衝罐216A、216B的側面上部設置的溢出噴嘴(未圖示)將緩衝罐216A、216B內的熱水排出，實施了雙重的溢出對策。 Further, a discharge valve (not shown) is provided at a lower portion of the buffer tanks 215A and 215B, and automatic control is performed so that when the measured values of the level gauges 216A and 216B provided in the buffer tank reach a set value, the discharge valve is opened. The hot water of the buffer tanks 216A, 216B is discharged, so that the hot water of the buffer tanks 216A, 216B does not overflow. Further, even when the discharge of the hot water is insufficient by the discharge valve, the hot water in the buffer tanks 216A and 216B is discharged by the overflow nozzle (not shown) provided on the upper portion of the side surface of each of the buffer tanks 216A and 216B. We implemented a double spill countermeasure.

接著針對熱水溫度的控制進行說明。電力資訊處理裝置211B參照溫度計217A、217B進行控制，以使得當這些溫度上升而達到各設定值時，打開注水閥214A或者注水閥214B，從注水裝置213將冷水注入緩衝罐215A或者/以及緩衝罐215B中，緩衝罐215A以及緩衝罐215B內的熱水溫度變為各設定值以下。進一步，參照測定向蒸發器23流入的熱水的溫度的溫度計217C進行控制，以使得當該溫度上升而達到設定值時，打開注水閥 214C而對從緩衝罐215A經由管道向熱水循環泵22A流動的熱水注入冷水，流入到蒸發器23中的熱水的溫度變為設定值以下。通過該機構，在因任何的異常使得熱水變為高溫而向蒸發器23流入的情況下，冷水直接被注入到與熱水循環泵22A連接的管道中，熱水溫度一下子變低，因此即使在異常時也能夠使火葬系統整體穩定運轉。另外，在上述內容中，針對從注水裝置213將冷水注入到緩衝罐215A或者/以及緩衝罐215B、與熱水循環泵22A連接的管道中的情況進行了說明，但是不限於冷水，即使是對高溫的介質進行冷卻的介質、例如在排放氣體/熱水熱交換器21與排放氣體進行熱交換的介質也是可以的。 Next, the control of the hot water temperature will be described. The power information processing device 211B performs control so as to refer to the thermometers 217A, 217B so that when these temperatures rise to reach the respective set values, the water injection valve 214A or the water injection valve 214B is opened, and the cold water is injected from the water injection device 213 into the buffer tank 215A or/and the buffer tank. In 215B, the temperature of the hot water in the buffer tank 215A and the buffer tank 215B becomes equal to or lower than each set value. Further, the thermometer 217C that measures the temperature of the hot water flowing into the evaporator 23 is controlled so that the water injection valve is opened when the temperature rises to reach the set value. At 214C, cold water is injected into the hot water flowing from the buffer tank 215A to the hot water circulation pump 22A via the pipe, and the temperature of the hot water flowing into the evaporator 23 becomes equal to or lower than the set value. With this mechanism, in the case where the hot water becomes high temperature due to any abnormality and flows into the evaporator 23, the cold water is directly injected into the pipe connected to the hot water circulation pump 22A, and the temperature of the hot water is suddenly lowered. The cremation system can be stably operated as a whole even in the event of an abnormality. Further, in the above description, the case where cold water is injected from the water injection device 213 into the buffer tank 215A or/and the buffer tank 215B and the piping connected to the hot water circulation pump 22A has been described, but it is not limited to cold water, even if it is A medium that is cooled by a high-temperature medium, for example, a medium that exchanges heat with the exhaust gas in the exhaust gas/hot water heat exchanger 21 is also possible.

接著針對本發明的雙循環發電系統19的另外的熱水溫度穩定化方法進行說明。在緩衝罐215A與蒸發器23之間設置旁路流路，通過電力資訊處理裝置211B，使用流量調整閥212A和流量調整閥212B，控制流入蒸發器23的熱水的流速，以使得來自緩衝罐215A的熱水的溫度或者熱量不超過設定值。具體而言，參照測定從蒸發器23流出的熱水的溫度Tout的溫度計217D，控制流量調整閥212A、212B，以使得該溫度Tout總是為設定溫度Tout(設定值)。即，當溫度Tout超過Tout(設定值)時，進行如下控制：將流量調整閥212B關小，抑制流入蒸發器23的熱水的流量，與此相反，打開流量調整閥212A，增大直接返回排放氣體/熱水熱交換器21的熱水的流量。與上述記載相反，在溫度Tout比Tout(設定值)低的情況下，進行如下控制：打開流量調整閥212B，使流入蒸發器23的熱水的流量增大，與此相反，將流量調整閥212A關小，抑制直接返回排放氣體/熱水熱交換器21的熱水的流量。通過上述的控制，即使是面對火葬系統特有的問題、即熱水 大幅的變動，也能夠大幅抑制流入蒸發器23的熱水的溫度變動，能夠使雙循環發電穩定運轉。 Next, another method of stabilizing the hot water temperature of the dual cycle power generation system 19 of the present invention will be described. A bypass flow path is provided between the buffer tank 215A and the evaporator 23, and the flow rate adjustment valve 212A and the flow rate adjustment valve 212B are used by the electric power information processing device 211B to control the flow rate of the hot water flowing into the evaporator 23 so as to be from the buffer tank. The temperature or heat of the hot water of 215A does not exceed the set value. Specifically, the flow rate adjustment valves 212A and 212B are controlled so that the temperature Tout is always the set temperature Tout (set value) with reference to the thermometer 217D that measures the temperature Tout of the hot water flowing out from the evaporator 23. That is, when the temperature Tout exceeds Tout (set value), the flow rate adjustment valve 212B is closed to suppress the flow rate of the hot water flowing into the evaporator 23, and conversely, the flow rate adjustment valve 212A is opened to increase the direct return. The flow rate of the hot water of the exhaust gas/hot water heat exchanger 21. Contrary to the above description, when the temperature Tout is lower than Tout (set value), the flow rate adjustment valve 212B is opened to increase the flow rate of the hot water flowing into the evaporator 23, and the flow rate adjustment valve is reversed. The 212A is closed to suppress the flow rate of the hot water directly returning to the exhaust gas/hot water heat exchanger 21. Through the above control, even the problem that is unique to the cremation system, namely hot water In the case of a large fluctuation, the temperature fluctuation of the hot water flowing into the evaporator 23 can be greatly suppressed, and the double-cycle power generation can be stably operated.

另外，在來自排放氣體/熱水熱交換器21的熱水的溫度較低的情況下，在一般的雙循環發電系統中會停止發電，但是在本發明的火葬系統中，電力資訊處理裝置211B控制流量調整閥212A和流量調整閥212B，使流入蒸發器23的熱水的流量增大，並且控制經由流量調整閥212B返回到排放氣體/熱水熱交換器21的熱水的流量。通過進行這樣的控制，在來自緩衝罐215A的熱水的溫度較低的情況下，能夠進行控制而使得流入蒸發器23的熱水的溫度不低。換而言之，即使排放氣體的溫度以及熱量大幅變化，本發明的火葬系統也能被控制而使得流入蒸發器23的熱水的溫度或者熱量一定，因此能夠穩定的進行發電，將所發電的電力穩定的供給到構成火葬系統的各裝置，由此能夠使火葬系統整體總是穩定的運轉。 Further, in the case where the temperature of the hot water from the exhaust gas/hot water heat exchanger 21 is low, power generation is stopped in the general two-cycle power generation system, but in the cremation system of the present invention, the power information processing device 211B The flow rate adjustment valve 212A and the flow rate adjustment valve 212B are controlled to increase the flow rate of the hot water flowing into the evaporator 23, and control the flow rate of the hot water returned to the exhaust gas/hot water heat exchanger 21 via the flow rate adjustment valve 212B. By performing such control, when the temperature of the hot water from the buffer tank 215A is low, it is possible to control so that the temperature of the hot water flowing into the evaporator 23 is not low. In other words, even if the temperature of the exhaust gas and the amount of heat largely change, the cremation system of the present invention can be controlled such that the temperature or heat of the hot water flowing into the evaporator 23 is constant, so that power generation can be stably performed, and the power generated can be generated. The supply of electric power to the devices constituting the cremation system is stabilized, so that the cremation system as a whole can always operate stably.

另外，在上述說明中，針對電力資訊處理裝置211B使用來自溫度計217A、217B、217C的溫度資訊控制注水閥214A、214B、214C的情況進行了說明，但是從火葬爐排出的排放氣體的溫度以及熱量，如使用第4圖說明的那樣，能夠根據火葬開始時間起的時間大致推定，因此，電力資訊處理裝置211B使用這些資訊，預先運算控制資料，從而控制注水閥214A、214B、214C也是可以的。 In the above description, the power information processing device 211B has been described using the temperature information from the thermometers 217A, 217B, and 217C to control the water injection valves 214A, 214B, and 214C, but the temperature and heat of the exhaust gas discharged from the cremation furnace are also described. As described with reference to Fig. 4, the time from the start of the cremation can be estimated roughly. Therefore, the power information processing device 211B can control the water injection valves 214A, 214B, and 214C by using the information in advance to calculate the control data.

接著參照第3圖，主要針對將由雙循環發電系統19發電的電力向構成火葬系統的各裝置供給的情況以及使用從各裝置輸入到電力資訊處理裝置211B的各種資訊進行的本發明的火葬系統的電力控制情況進行說明。 Referring to Fig. 3, the cremation system of the present invention is mainly applied to the case where the electric power generated by the two-cycle power generation system 19 is supplied to each device constituting the cremation system and the various information input from the respective devices to the electric power information processing device 211B. The power control situation is explained.

在第3圖中，粗線表示電力的流動，細線表示控制信號，虛線表示來自設置在各裝置上的各種感測器的檢測信號。另外，116表示將在熱風回收熱交換器110產生的熱風送到主燃爐11的熱風回收路徑。另外，在第3圖中，電力控制裝置211A和電力資訊處理裝置211B被記載為存在於雙循環發電系統19的外部的裝置，但是電力控制裝置211A和電力資訊處理裝置211B構成為雙循環發電系統19的一部分也可以，另外，電力控制裝置211A和電力資訊處理裝置211B構成為火葬系統控制裝置31的一部分也可以。進一步，電力控制裝置211A和電力資訊處理裝置211B構成為一體也可以。即，電力控制裝置211A、電力資訊處理裝置211B、火葬系統控制裝置31的組合結構，能夠與硬體、軟體、固件的結構相配合而靈活的進行。另外，電力資訊處理裝置211B、火葬系統控制裝置31的控制以軟體控制為主，但是也可以是由一部分硬體控制的結構。 In Fig. 3, thick lines indicate the flow of electric power, thin lines indicate control signals, and broken lines indicate detection signals from various sensors provided on the respective devices. Further, reference numeral 116 denotes a hot air collecting path for sending the hot air generated in the hot air recovery heat exchanger 110 to the main combustion furnace 11. In addition, in FIG. 3, the power control device 211A and the power information processing device 211B are described as being present outside the two-cycle power generation system 19, but the power control device 211A and the power information processing device 211B are configured as a dual-cycle power generation system. A part of 19 may be used. Further, the power control device 211A and the power information processing device 211B may be configured as part of the cremation system control device 31. Further, the power control device 211A and the power information processing device 211B may be integrally formed. In other words, the combined configuration of the power control device 211A, the power information processing device 211B, and the cremation system control device 31 can be flexibly performed in cooperation with the configuration of the hardware, the software, and the firmware. Further, the control of the power information processing device 211B and the cremation system control device 31 is mainly based on software control, but may be controlled by a part of hardware.

在第3圖中，針對將主要控制電力的電力控制裝置211A與主要處理類比信號或者數位信號的電力資訊處理裝置211B分開的結構進行了說明，下面針對其理由進行說明。由於電力控制裝置211A處理大的電力，因此向周邊輻射雜訊，當該雜訊混入到電力資訊處理裝置211B內部的類比電路或者抗雜訊性能差的電路中時，這些電路發生誤動作，電力資訊處理裝置211B的控制有可能發生誤動作或者變得不穩定。而通過使電力控制裝置211A與電力資訊處理裝置211B的電源線分離開，或者對電力資訊處理裝置211B實施屏蔽等，從電力控制裝置211A大量產生的雜訊混入到電力資訊處理裝置211B中而使電力資訊處理裝置211B誤動作的情況不會發生。 In the third diagram, the configuration in which the power control device 211A that mainly controls the power is separated from the power information processing device 211B that mainly processes the analog signal or the digital signal has been described. The reason will be described below. Since the power control device 211A processes the large power, the noise is radiated to the periphery, and when the noise is mixed into the analog circuit inside the power information processing device 211B or the circuit with poor noise resistance, the circuits malfunction. The control of the processing device 211B may malfunction or become unstable. By separating the power control device 211A from the power supply line of the power information processing device 211B or shielding the power information processing device 211B, the noise generated from the power control device 211A is mixed into the power information processing device 211B. The case where the power information processing device 211B malfunctions does not occur.

接著參照第3圖進行具體說明。電力控制裝置211A將由雙循 環發電系統19發電的電力供給到構成火葬系統的各裝置，具體而言，供給到主燃爐11、再燃爐13、構成雙循環發電系統19的熱水循環泵22A等電氣設備、熱風回收熱交換器110、電集塵裝置112、催化裝置113、排風機114、構成電力資訊處理裝置211B的CPU、記憶體等電子設備、火葬系統的其他的裝置30、具體而言是第1圖中記載的主燃燃燒器12、自動收棺裝置15等。 Next, specific description will be given with reference to FIG. Power control device 211A will be double-circulated The electric power generated by the ring power generation system 19 is supplied to each of the devices constituting the cremation system, specifically, to the main combustion furnace 11, the reburning furnace 13, the hot water circulation pump 22A constituting the dual cycle power generation system 19, and the like, and the hot air heat recovery. The exchanger 110, the electric dust collector 112, the catalytic device 113, the exhaust fan 114, the CPU constituting the power information processing device 211B, an electronic device such as a memory, and another device 30 of the cremation system are specifically described in FIG. The main combustion burner 12, the automatic winding device 15, and the like.

另一方面，來自在主燃爐11、再燃爐13、雙循環發電系統19、熱風回收熱交換器110、電集塵裝置112等上設置的各種感測器(具體而言是流量計、各種溫度計、壓力計、氧濃度計、排煙濃度計等)的信號分別輸入到電力資訊處理裝置211B，使用這些資訊，由電力資訊處理裝置211B進行運算處理，將以運算結果為基礎而生成的控制信號向電力控制裝置211A輸出。 On the other hand, various sensors (specifically, flow meters, various types) provided on the main combustion furnace 11, the reburning furnace 13, the dual-cycle power generation system 19, the hot air recovery heat exchanger 110, the electric dust collecting device 112, and the like The signals of the thermometer, the pressure gauge, the oxygen concentration meter, the exhaust gas concentration meter, and the like are input to the power information processing device 211B, and the information is processed by the power information processing device 211B using the information, and the control generated based on the calculation result is generated. The signal is output to the power control device 211A.

如上所述，從主燃爐11以及再燃爐13排出的排放氣體的溫度以及熱量大幅變動，本發明的雙循環發電系統19進行控制而極力抑制該變動引起的電力變動，但是一定程度的變動不可避免。而計算出各裝置所需要的電力，針對不足部分的電力，進行控制以使得來自外部電源32的電力加到由雙循環發電系統19發電的電力之中，而向各裝置供給電力，使得對各裝置的電力供給穩定。 As described above, the temperature and heat of the exhaust gas discharged from the main combustion furnace 11 and the reburning furnace 13 greatly vary, and the two-cycle power generation system 19 of the present invention controls the power fluctuation caused by the fluctuation as much as possible, but the fluctuation of the degree is not possible. avoid. On the other hand, the power required for each device is calculated, and the power of the insufficient portion is controlled so that the electric power from the external power source 32 is added to the electric power generated by the dual-cycle power generation system 19, and the electric power is supplied to each device so that each The power supply to the device is stable.

另外，由雙循環發電系統19發電的電力以及各裝置所需要的電力，根據火葬爐的運用狀況能夠預先計算出，據此，也可以構成為，電力資訊處理裝置211B使用所計算出的電力資訊進行控制，使得火葬系統整體以及構成火葬系統的各裝置不會發生電力不足的情況。 In addition, the electric power generated by the dual-cycle power generation system 19 and the electric power required for each device can be calculated in advance based on the operation state of the cremation furnace, and accordingly, the electric power information processing device 211B can be configured to use the calculated electric power information. Control is performed so that the entire cremation system and the devices constituting the cremation system do not suffer from power shortage.

另外，備用電源33，為在外部電源32由於發生事故或者自然 災害等而一時無法使用的情況下所準備，具有備用的作用。即，在來自外部電源32的電源供給停止的情況下，根據來自電力資訊處理裝置211B的控制信號或者來自外部電源32的信號，立即啟動備用電源33，將對電力控制裝置211A的電力供給從外部電源32切換到備用電源33。作為火葬系統的特徵，無論怎樣的情況下，火葬都需要穩定的進行，備用電源33在緊急時刻是有效的，但不是本火葬系統必須的裝置。 In addition, the backup power source 33 is in the external power source 32 due to an accident or natural It is prepared in the case of a disaster that cannot be used for a while, and has an alternate function. In other words, when the power supply from the external power source 32 is stopped, the backup power source 33 is immediately activated based on the control signal from the power information processing device 211B or the signal from the external power source 32, and the power supply to the power control device 211A is supplied from the outside. The power source 32 is switched to the backup power source 33. As a feature of the cremation system, cremation needs to be carried out in a stable manner, and the backup power source 33 is effective in an emergency, but it is not a necessary device for the cremation system.

接著參照第5圖~第8圖，針對本發明的火葬系統的實驗資料進行說明。第5圖是表示第1圖所示再燃爐13的再燃爐溫度隨時間變化的曲線圖，針對並列運轉的兩個火葬爐、A號爐和B號爐幾乎同時運轉的情況，用虛線表示A號爐的溫度變化，用實線表示B號爐的溫度變化。在此，從A號爐的共通煙道排出的排放氣體和從B號爐的共通煙道排出的排放氣體被排出到共同的排氣通道18B，流入雙循環發電系統19的排放氣體/熱水熱交換器21。 Next, the experimental data of the cremation system of the present invention will be described with reference to Figs. 5 to 8 . Fig. 5 is a graph showing the change of the temperature of the reburning furnace of the reburning furnace 13 shown in Fig. 1 with time, and the two cremation furnaces, the A furnace and the B furnace operating in parallel are operated at almost the same time, and the dotted line indicates A. The temperature change of the furnace, the solid line indicates the temperature change of the No. B furnace. Here, the exhaust gas discharged from the common flue of the furnace No. A and the exhaust gas discharged from the common flue of the No. B furnace are discharged to the common exhaust passage 18B, and the exhaust gas/hot water flowing into the double-cycle power generation system 19 is discharged. Heat exchanger 21.

在一天的火葬運轉開始之前，將主燃燃燒器12和再燃燃燒器都開動，對A號爐和B號爐進行暖氣運轉。在實驗中，A號爐、B號爐的暖氣運轉分別運轉t51、t51’時間，通過這些暖氣運轉，各再燃爐的溫度上升到接近再燃爐的設定溫度T2的溫度。 Before the start of the cremation operation of one day, both the main burner 12 and the reburning burner were started, and the heating operation was performed on the No. A furnace and the No. B furnace. In the experiment, the heating operation of the No. A furnace and the No. B furnace was operated for t51 and t51', respectively, and the temperature of each reburning furnace was raised to a temperature close to the set temperature T2 of the reburning furnace by these heating operations.

在暖氣運轉之後，伴隨著主燃燃燒器12和再燃燃燒器的開動停止，各再燃爐13的溫度暫時下降，但是之後，在時刻t55，A號爐開始運轉，在時刻t55’，B號爐開始運轉，這樣，各再燃爐13的溫度再次上升到溫度T2附近。而在A號爐、B號爐分別持續運轉t52、t52’時間之後，兩個火葬爐的運轉停止，伴隨與此，在主燃爐11的前面設置的隔熱門開放，外氣流 入到主燃爐11以及再燃爐13中，各再燃爐13的溫度急速下降。之後，第二次的火葬所具備的暖氣運轉再次在時刻t56’、t56開始，以後重複上述的作業。第二次的暖氣運轉，由於主燃爐11以及再燃爐13都處於溫暖到一定溫度以上的狀態，因此暖氣運轉期間t53、t53’比第一次的暖氣運轉期間t51、t51’大幅縮短。 After the heating operation, the temperature of each reburning furnace 13 temporarily drops as the start of the main combustion burner 12 and the reburning burner is stopped, but thereafter, at time t55, the furnace No. A starts to operate, and at time t55', the furnace No. B The operation is started, and thus the temperature of each of the reburning furnaces 13 rises again to the vicinity of the temperature T2. On the other hand, after the operation of the No. 2 furnace and the No. B furnace continued for t52 and t52', the operation of the two cremation furnaces was stopped, and accordingly, the heat insulating door provided in front of the main combustion furnace 11 was opened, and the external airflow was opened. When the main burner 11 and the reburning furnace 13 are introduced, the temperature of each of the reburning furnaces 13 is rapidly lowered. After that, the heating operation of the second cremation station starts again at times t56' and t56, and the above-described work is repeated thereafter. In the second heating operation, since both the main combustion furnace 11 and the reburning furnace 13 are warmed to a certain temperature or higher, the heating operation periods t53 and t53' are significantly shortened compared with the first heating operation periods t51 and t51'.

接著參照第6圖，針對從A號爐、B號爐的各再燃爐13排出的排放氣體流量隨時間的變化進行說明。橫軸為與第5圖相同的時間軸，暖氣運轉、A號爐、B號爐的開動/停止的各時刻也與第5圖相同，這在第7圖以及第8圖中也是同樣的。另外，縱軸表示將從A號爐、B號爐的各再燃爐13排出的各排放氣體流量相加得到的排放氣體流量。如上所述，在初始階段，排放氣體一時大量產生，從曲線圖也可知，在時刻t62、t63，排放氣體急速增加，之後急速減少。另外，在時刻t61，表面上排放氣體流量急速增加，這是因為在將棺材17置入主燃爐11中時將主燃爐11前面的隔熱門打開，這時，空氣一時流入到主燃爐11以及再燃爐13中。 Next, with reference to Fig. 6, a description will be given of changes in the flow rate of the exhaust gas discharged from each of the reburning furnaces 13 of the No. 2 furnace and the No. B furnace with time. The horizontal axis is the same time axis as that of Fig. 5, and the respective times of the heating operation, the No. A furnace, and the No. B furnace are also the same as in Fig. 5, which is the same in Figs. 7 and 8. Further, the vertical axis indicates the flow rate of the exhaust gas obtained by adding the respective exhaust gas flows discharged from the respective reburning furnaces 13 of the No. 2 furnace and the No. B furnace. As described above, in the initial stage, the exhaust gas is generated in a large amount at a time, and as is also known from the graph, at time t62, t63, the exhaust gas rapidly increases, and then rapidly decreases. Further, at time t61, the discharge gas flow rate on the surface is rapidly increased because the heat insulating door in front of the main combustion furnace 11 is opened when the coffin 17 is placed in the main combustion furnace 11, and at this time, the air flows into the main combustion furnace 11 at a time. And in the reburning furnace 13.

接著參照第7圖，針對蒸發器23的流入口的溫度、即溫度Tin隨時間的變化進行說明。溫度Tin伴隨著暖氣運轉而持續上升，伴隨著A號爐以及B號爐的運轉開始而進一步急速上升，達到溫度T72。即，根據第6圖可知，在火葬開始初期，產生大量的排放氣體熱量，基於該熱量，從火葬開始起直至時刻t71止，溫度Tin急速上升。之後伴隨著排放氣體熱量的減少，溫度Tin持續下降，與暖氣運轉的開始一樣變為一定溫度T71，之後伴隨著A號爐以及B號爐的運轉開始而上升，重複進行上述的動作。 Next, referring to Fig. 7, the temperature of the inlet of the evaporator 23, that is, the change of the temperature Tin with time will be described. The temperature Tin continues to rise with the heating operation, and further increases rapidly with the start of the operation of the No. A furnace and the No. B furnace, and reaches the temperature T72. That is, according to Fig. 6, it is understood that a large amount of exhaust gas heat is generated at the beginning of the cremation, and the temperature Tin rapidly rises from the start of the cremation to the time t71 based on the heat. Then, as the amount of heat of the exhaust gas decreases, the temperature Tin continues to decrease, and becomes a constant temperature T71 as in the start of the heating operation, and then rises with the start of the operation of the No. A furnace and the No. B furnace, and the above-described operation is repeated.

在本發明的火葬系統中，即使排放氣體的溫度以及排放氣體 流量大幅變化，排放氣體的熱量大幅變化，基於上述的機構，也能夠進行控制以使得流入蒸發器23的熱水溫度穩定化。接著，針對相對於排放氣體的熱量變化，溫度Tin的變動率被抑制了多少進行估算。 In the cremation system of the present invention, even the temperature of the exhaust gas and the exhaust gas The flow rate greatly changes, and the heat of the exhaust gas largely changes. Based on the above mechanism, it is also possible to control so that the temperature of the hot water flowing into the evaporator 23 is stabilized. Next, for the change in the amount of heat with respect to the exhaust gas, the rate of change of the temperature Tin is suppressed to be estimated.

1)排放氣體溫度的變動 1) Change in exhaust gas temperature

根據第5圖，排放氣體溫度在溫度T1~T2的範圍內變動，據此可知，變動率為T2/((T1+T2)/2)≒44%。 According to Fig. 5, the exhaust gas temperature fluctuates within the range of the temperature T1 to T2, and accordingly, the variation rate is T2/((T1+T2)/2) ≒ 44%.

2)排放氣體流量的變動率 2) Rate of change of exhaust gas flow rate

根據第6圖，排放氣體流量在流量Q1~Q2的範圍內變動，據此可知，變動率為Q2/((Q1+Q2)/2)≒70%。 According to Fig. 6, the flow rate of the exhaust gas fluctuates within the range of the flow rates Q1 to Q2. From this, it is understood that the variation rate is Q2/((Q1+Q2)/2) ≒ 70%.

3)排放氣體熱量的變動率 3) The rate of change of exhaust gas heat

若使得排放氣體熱量與(排放氣體溫度)×(排放氣體流量)成比例，則排放氣體熱量的變動率為44%+70%=114%。 If the exhaust gas heat is proportional to (exhaust gas temperature) x (discharge gas flow rate), the rate of change of the exhaust gas heat is 44% + 70% = 114%.

4)不進行使熱水溫度穩定化的控制時的熱水溫度的變動率 4) The rate of change of the hot water temperature when the control for stabilizing the hot water temperature is not performed

若使得排放氣體熱量的變動率與熱水溫度的變動率成比例，則不進行使熱水溫度穩定化的控制時的熱水溫度的變動率為114%。 When the rate of change of the exhaust gas heat is proportional to the rate of change of the hot water temperature, the rate of change of the hot water temperature when the control for stabilizing the hot water is not performed is 114%.

另一方面，根據第7圖，溫度Tin的變動率為T72/((T71+T72)/2)≒9%。據此可知，通過基於本發明的熱水溫度的穩定化控制，相對於不進行使熱水溫度穩定化的控制時的熱水溫度的變動率，能夠將變動抑制為9%/114%≒8%的程度。 On the other hand, according to Fig. 7, the rate of change of the temperature Tin is T72 / ((T71 + T72) / 2) ≒ 9%. According to this, it is understood that the fluctuation of the hot water temperature at the time of the control for stabilizing the hot water can be suppressed to 9%/114% by the stabilization control of the hot water temperature according to the present invention. %Degree.

接著參照第8圖，針對由本發明的火葬系統發電的發電量和將構成火葬系統的各設備的設備使用電力合計而得到的總設備使用電力隨時間的變化進行說明。在第8圖中，虛線表示由雙循環發電系統19發電的發 電量，實線表示總設備使用電力。發電量在A號爐、B號爐的暖氣運轉結束與火葬開始時刻t55，t55’之間的時刻開始上升，比第7圖的溫度Tin達到峰值的時刻推遲5分鐘~15分鐘左右，在時刻t81附近達到峰值。之後，根據第7圖可知，溫度Tin較低，相應於此，發電量也低，當第二次的暖氣運轉開始時，發電量再次增加，以後重複該週期。 Next, a description will be given of a change in the total equipment use power with time obtained by the total amount of power generated by the cremation system of the present invention and the total amount of power used by the equipment constituting each device of the cremation system. In Fig. 8, the broken line indicates the power generated by the dual-cycle power generation system 19. The amount of electricity, the solid line indicates the total equipment use of electricity. The amount of power generation starts to rise at the time between the end of the heating operation of the No. A furnace and the No. B furnace and the cremation start time t55, t55', and is delayed by about 5 minutes to 15 minutes from the time when the temperature Tin of the seventh figure reaches the peak. The peak is reached near t81. Thereafter, as can be seen from Fig. 7, the temperature Tin is low, and accordingly, the amount of power generation is also low. When the second heating operation is started, the amount of power generation increases again, and the cycle is repeated thereafter.

另一方面，總設備電力伴隨著A號爐以及B號爐的火葬開始而急速達到峰值。這是因為，根據第6圖可知，在該期間，排放氣體流量達到峰值，為了處理該大量的排放氣體，排風機114的使用電力急速增加。之後，總設備電力相應於各設備的開動而增減，但是就平均而言，伴隨著火葬的進展直至結束而逐漸減少。 On the other hand, the total equipment power rapidly peaked with the cremation of the A and B furnaces. This is because, as can be seen from Fig. 6, during this period, the exhaust gas flow rate reaches a peak value, and the power consumption of the exhaust fan 114 is rapidly increased in order to process the large amount of exhaust gas. After that, the total equipment power is increased or decreased corresponding to the start of each equipment, but on average, it gradually decreases as the cremation progresses to the end.

接著，針對將發電量按時間積分得到的發電累計量與將總設備電力按時間積分得到的設備電力累計量之比，即針對電氣收支(=發電累計量/總設備電力累計量)進行說明。根據第8圖可知，第一次火葬的電氣收支為53%，第二次火葬的電氣收支為46%，第一次和第二次的電氣收支的平均為50%，實現了高效率的雙循環發電系統19。另外，從表面上來看，第二次的電氣收支比第一次的電氣收支要低，根據第7圖可知，這是因為第二次的暖氣運轉的期間短而造成第二次的暖氣運轉中的溫度Tin低下，這並不意味著火葬運轉時實質的電氣收支低下。 Next, the ratio of the cumulative amount of power generation obtained by integrating the amount of power generation with the cumulative amount of equipment power obtained by integrating the total equipment power over time, that is, the electric revenue and expenditure (= cumulative power generation amount / total equipment power accumulated amount) will be described. . According to Figure 8, the electrical revenue of the first cremation was 53%, the electrical revenue of the second cremation was 46%, and the average of the first and second electrical revenues was 50%, which was high. An efficient dual cycle power generation system 19. In addition, on the surface, the second electrical revenue is lower than the first electrical revenue. According to Figure 7, this is because the second heating operation is short and the second heating is caused. The temperature Tin in operation is low, which does not mean that the actual electrical balance is low when the cremation is running.

<第二實施方式> <Second Embodiment>

接著參照第9圖，針對本發明的火葬系統的第二實施方式進行說明。在上述中針對A號爐和B號爐同時運轉的情況進行了說明，但是更加普遍的情況是，運轉的時刻獨立的兩個爐以上的多個火葬爐並列設置， 將它們作為一個成套設備也可以。 Next, a second embodiment of the cremation system of the present invention will be described with reference to Fig. 9.
