參照圖1對第一實施形態進行說明。The first embodiment will be described with reference to FIG. 1.

要被進行RO處理的原水自配管1由泵2供給至加熱泵10的冷凝器13，被加熱後自配管3通過以蒸氣為熱源的熱交換器4（第二熱交換器），並經由配管5而被供給至RO裝置6。RO裝置6的透過水是自配管7作為處理水而取出，而濃縮水流出至配管8。The raw water to be RO-treated is supplied from the piping 1 to the condenser 13 of the heat pump 10 by the pump 2, and after being heated, the piping 3 passes through the heat exchanger 4 (second heat exchanger) using steam as a heat source and passes through the piping 5 is supplied to the RO device 6. The permeated water of the RO device 6 is taken out from the pipe 7 as treated water, and the concentrated water flows out to the pipe 8.

用於對熱交換器4供給蒸氣的鍋爐（boiler）的形式並無特別限定，可為小型直流鍋爐、水管鍋爐、圓鍋爐、排熱鍋爐等中的任一者。另外，在通常運轉時不需要利用蒸氣進行加溫，但在後述的冷凍機主體21的停止時或RO裝置6的啟動時等的加溫等中使用。但是，亦可視需要在通常運轉時亦利用熱交換器4對RO給水進行加熱。The form of a boiler for supplying steam to the heat exchanger 4 is not particularly limited, and may be any one of a small once-through boiler, a water tube boiler, a round boiler, a heat exhaust boiler, and the like. In addition, it is not necessary to use steam for heating during normal operation, but it is used for heating such as when the refrigerator body 21 described below is stopped or when the RO device 6 is started. However, the heat exchanger 4 may also be used to heat the RO feed water during normal operation as needed.

加熱泵10為周知的構成，構成為：將來自蒸發器11的氟氯烷替代品等的熱媒體用壓縮機12藉由隔熱壓縮製成高溫後導入至冷凝器13，並將來自冷凝器13的熱媒體經由膨脹閥14而導入至蒸發器11，使其隔熱膨脹並降溫。原水經由泵2而通水至冷凝器13內所設的導熱管13a，與高溫熱媒體進行熱交換而被加熱。The heat pump 10 has a well-known configuration, and is configured to introduce a heat medium compressor 12 such as a chlorofluorocarbon substitute from the evaporator 11 into a high temperature by heat insulation compression, and then introduce it to the condenser 13 and pass it from the condenser The heat medium 13 is introduced into the evaporator 11 via the expansion valve 14 to thermally expand and cool down. The raw water passes through the pump 2 to the heat transfer tube 13a provided in the condenser 13, and is heated by heat exchange with a high-temperature heat medium.

自冷凍系統20的熱交換器24流出的溫媒體的一部分經由配管31及閥32而被導入至蒸發器11內所設的導熱管11a。藉由與蒸發器11內的低溫熱媒體的熱交換而降溫的冷媒體經由配管33而再度被導入至熱交換器24。A part of the temperature medium flowing out of the heat exchanger 24 of the freezing system 20 is introduced into the heat transfer tube 11 a provided in the evaporator 11 through the pipe 31 and the valve 32. The cold medium whose temperature has been reduced by heat exchange with the low-temperature heat medium in the evaporator 11 is introduced into the heat exchanger 24 again through the pipe 33.

冷凍系統20將由渦輪式冷凍機、抽吸式冷凍機等冷凍機主體21冷卻的冷媒體自冷凍機主體21的媒體送出部21a經由配管22而供給至空調機等的熱交換器24（第一熱交換器），使其吸收周圍的熱而將所述周圍冷卻。利用熱交換器24吸收所述周圍的熱而升溫的溫媒體的一部分自熱交換器24經由媒體循環用泵25、配管26、閥27而返回至冷凍機主體21的媒體返回部21b。The refrigeration system 20 supplies the cold medium cooled by the refrigerator body 21 such as a turbo refrigerator, a suction refrigerator, etc. from the medium sending part 21a of the refrigerator body 21 to the heat exchanger 24 (first Heat exchanger), so that it absorbs the surrounding heat and cools the surrounding. A part of the temperature medium that has increased in temperature by absorbing the surrounding heat by the heat exchanger 24 returns from the heat exchanger 24 to the medium return portion 21b of the refrigerator body 21 via the medium circulation pump 25, the piping 26, and the valve 27.

自熱交換器24流出的溫媒體的剩餘部分經由自配管26分支的配管31、閥32而流通至蒸發器11的導熱管11a，與加熱泵熱媒體進行熱交換而降溫成為冷媒體，並流出至配管33。配管33與所述配管22連通，所以來自配管33的冷媒體與來自所述冷凍機主體21的冷媒體合流而流入至熱交換器24。The remaining part of the warm medium flowing out of the heat exchanger 24 flows through the piping 31 branched from the piping 26 and the valve 32 to the heat transfer tube 11a of the evaporator 11, exchanges heat with the heat pump heat medium, and the temperature is reduced to a cold medium and flows out To piping 33. Since the piping 33 communicates with the piping 22, the cooling medium from the piping 33 merges with the cooling medium from the freezer body 21 and flows into the heat exchanger 24.

如此，在此實施形態中，作為在加熱泵10的蒸發器11的導熱管11a中流通的熱源流體，利用了自熱交換器24流出的溫媒體。而且，使藉由通過加熱泵10的蒸發器11的導熱管11a而降溫的冷媒體返回至熱交換器24。In this way, in this embodiment, as the heat source fluid flowing through the heat pipe 11 a of the evaporator 11 of the heat pump 10, the warm medium flowing out of the heat exchanger 24 is used. Then, the cold medium whose temperature is lowered by the heat transfer tube 11 a of the evaporator 11 of the heat pump 10 is returned to the heat exchanger 24.

另外，此冷凍系統20的冷凍機主體21使用了來自冷卻塔40的冷水作為冷卻用的低溫流體。In addition, the chiller body 21 of this refrigeration system 20 uses cold water from the cooling tower 40 as a low-temperature fluid for cooling.

在此冷卻塔40中，由灑水管41進行灑水的冷卻水在自填充材層42中流下期間與自百葉窗（Louver）43導入的空氣接觸，藉由蒸發潛熱而受到冷卻成為冷水，並貯留於池（pit）44（冷卻塔下部水槽）。包含蒸氣的空氣藉由排氣扇（fan）48而排氣至大氣中。池44的冷水經由泵45、配管46而被供給至冷凍機主體21，並進行熱交換而升溫。來自冷凍機主體21的回溫水經由配管47而被返送至灑水管41。In this cooling tower 40, the cooling water sprinkled by the sprinkling pipe 41 comes into contact with the air introduced from the Louver 43 while flowing down from the filling material layer 42 and is cooled into cold water by latent heat of evaporation and stored Yu pool (pit) 44 (sink in the lower part of the cooling tower). The air containing steam is exhausted into the atmosphere by a fan 48. The cold water of the pond 44 is supplied to the freezer body 21 via the pump 45 and the piping 46, and heat exchange is performed to increase the temperature. The warm water from the refrigerator main body 21 is returned to the sprinkler pipe 41 via the pipe 47.

在如此構成的圖1的逆滲透處理裝置中，原水在由加熱泵10加熱後，視需要由熱交換器4進行加熱，而被供給至RO裝置6。In the reverse osmosis treatment device of FIG. 1 configured as above, the raw water is heated by the heat pump 10 and then heated by the heat exchanger 4 as necessary, and then supplied to the RO device 6.

在此實施形態中，作為加熱泵10的溫熱源，使用了自冷凍系統20中所設置的空調機等的熱交換器24流出的溫媒體，所以可降低冷凍機主體21的冷凍負荷。而且，因可藉此降低冷凍機主體21的消耗電力，所以由加熱泵10消耗的電力幾乎被抵消。因此，可將加溫用的蒸氣的削減額直接作為效益來計入，因此可儘早回收設置加熱泵的投資。In this embodiment, as the heat source of the heat pump 10, the temperature medium flowing out of the heat exchanger 24 such as an air conditioner provided in the refrigeration system 20 is used, so the refrigeration load of the refrigerator body 21 can be reduced. Furthermore, since the power consumption of the refrigerator body 21 can be reduced by this, the power consumed by the heat pump 10 is almost cancelled. Therefore, the amount of steam reduction for heating can be directly included as a benefit, so the investment for installing a heat pump can be recovered as soon as possible.

參照圖2對第二實施形態進行說明。The second embodiment will be described with reference to FIG. 2.

在圖1的冷凍系統20中，是使自冷凍機主體21經由配管22而送來的冷媒體與自蒸發器11經由配管33而送來的冷媒體合流後流入至空調機等的熱交換器24，但在圖2的實施形態中，是僅使自冷凍機主體21的媒體送出部21a經由配管22而送來的冷媒體流入至熱交換器24。In the freezing system 20 of FIG. 1, the cooling medium sent from the main body 21 of the refrigerator through the piping 22 and the cooling medium sent from the evaporator 11 through the piping 33 merge, and then flow into a heat exchanger such as an air conditioner. 24. However, in the embodiment of FIG. 2, only the cold medium sent from the medium sending part 21 a of the freezer body 21 through the pipe 22 flows into the heat exchanger 24.

自所述熱交換器24流出的溫媒體藉由媒體循環用泵25送出至配管28。被送出的溫媒體的一部分經由閥29、配管30而循環至冷凍機主體21的媒體返回部21b。The warm medium flowing out of the heat exchanger 24 is sent to the piping 28 by the medium circulation pump 25. A part of the sent warm medium is circulated to the medium return part 21b of the freezer body 21 via the valve 29 and the pipe 30.

被送出至配管28的溫媒體的剩餘部分經由自配管28分支的配管35及閥36而流通至蒸發器11的導熱管11a，與加熱泵熱媒體進行熱交換而降溫成為冷媒體，並自配管37合流至配管30，返回至冷凍機主體21的媒體返回部21b。The remaining part of the temperature medium sent to the pipe 28 flows to the heat transfer pipe 11a of the evaporator 11 through the pipe 35 and the valve 36 branched from the pipe 28, exchanges heat with the heat pump heat medium, and the temperature is reduced to a cold medium, and the pipe 37 joins to the piping 30, and returns to the medium return part 21b of the freezer main body 21.

圖2的其他構成與圖1相同，同一符號表示同一部分。The other configuration of FIG. 2 is the same as that of FIG. 1, and the same symbol indicates the same part.

在此實施形態中，亦與圖1的實施形態同一地，作為加熱泵10的溫熱源，使用了自冷凍系統20中所設置的空調機等的熱交換器24流出的溫媒體，所以可降低冷凍機主體21的冷凍負荷。In this embodiment, as in the embodiment of FIG. 1, as the heat source of the heat pump 10, a temperature medium flowing out from a heat exchanger 24 such as an air conditioner provided in the refrigeration system 20 is used, so it is possible The freezing load of the refrigerator body 21 is reduced.

另外，按照圖1的系統將原水（20℃）加熱至25℃後以100 m3 /h進行RO處理，而以性能係數（Coefficient Of Performance，COP）5來運轉作為冷凍機主體21的渦輪冷凍機（500 RT），將冷凍機主體21的媒體設為水，並設冷凍機主體返回部21b的流入水（溫媒體）溫度為12℃、冷凍機主體送出部21a的流出水（冷媒體）溫度為7℃，不對熱交換器4供給蒸氣，以COP（性能係數）6來運轉加熱泵（470 kW）的情況下，據估算，與僅藉由蒸氣式熱交換器4來將原水自20℃加溫至25℃，而利用3台小型直流鍋爐（換算蒸發量2000 kg/h、燃料液化天然氣（liquified natural gas，LNG）、蒸氣壓力0.7 MPa）對蒸氣式熱交換器4供給蒸氣的情況相比，能量成本成為80%以下。In addition, according to the system of FIG. 1, the raw water (20° C.) is heated to 25° C. and then subjected to RO treatment at 100 m 3 /h, and the turbine refrigeration, which is the main body 21 of the refrigerator, is operated with a coefficient of performance (COP) 5 Machine (500 RT), the medium of the freezer body 21 is set to water, and the temperature of the inflow water (warm medium) of the freezer body return part 21b is 12°C, and the outflow water (cold medium) of the freezer body delivery part 21a When the temperature is 7°C, and the heat pump 4 is not supplied with steam, and the heat pump (470 kW) is operated with COP (coefficient of performance) 6, it is estimated that the raw water is removed from 20 ℃ heating to 25 ℃, and using three small once-through boilers (converted evaporation 2000 kg/h, fuel liquefied natural gas (LNG), vapor pressure 0.7 MPa) to supply steam to the steam heat exchanger 4 In comparison, the energy cost becomes less than 80%.

而且，圖1的系統據估算與僅藉由加熱泵將原水自20℃加溫至25℃的情況相比，能量成本成為90%以下。Furthermore, the system of FIG. 1 is estimated to have an energy cost of less than 90% compared to the case where the raw water is heated from 20°C to 25°C only by the heat pump.

參照圖3對第三實施形態進行說明。The third embodiment will be described with reference to FIG. 3.

在圖1中，通過加熱泵10的冷凝器13的導熱管13a而被加熱的原水其全部量自配管3被送水至熱交換器4，並且自鍋爐對熱交換器4供給蒸氣作為熱源流體。在圖3中，使所述配管3分支為配管50、配管60的兩個系統。In FIG. 1, the entire amount of raw water heated by the heat transfer tube 13 a of the condenser 13 of the heat pump 10 is sent from the piping 3 to the heat exchanger 4, and steam is supplied from the boiler to the heat exchanger 4 as a heat source fluid. In FIG. 3, the piping 3 is branched into two systems of piping 50 and piping 60.

流至配管50的加熱原水經由閥51、給水槽52及配管53而被送水至熱交換器4。而且，對給水槽52連接有具有閥85的配管86，以便將不會由加熱泵10進行加熱的原水（以下，有時記載為「非加熱原水」）供給至給水槽52。The heated raw water flowing to the pipe 50 is sent to the heat exchanger 4 via the valve 51, the water supply tank 52 and the pipe 53. In addition, a pipe 86 having a valve 85 is connected to the water supply tank 52 so that raw water (hereinafter, sometimes referred to as “non-heated raw water”) that is not heated by the heat pump 10 is supplied to the water supply tank 52.

流至配管60的加熱原水經由閥61、第一軟水器62及配管63而被送水至給水槽64。亦將通過第二軟水器65的鍋爐用水經由配管66而導入至給水槽64。軟水器62、軟水器65具有容器及填充在所述容器內的離子交換樹脂，將原水或鍋爐用水製成軟水。鍋爐用水可為來自與原水同一水源的水，亦可為來自另外的水源的水。The heated raw water flowing to the piping 60 is sent to the water supply tank 64 via the valve 61, the first water softener 62, and the piping 63. The boiler water passing through the second water softener 65 is also introduced into the water supply tank 64 through the piping 66. The water softener 62 and the water softener 65 have a container and an ion exchange resin filled in the container, and make raw water or boiler water into soft water. The boiler water may be water from the same water source as the raw water, or water from another water source.

給水槽64內的水經由配管67而被供給至鍋爐70。鍋爐70中產生的蒸氣經由配管71而被供給至熱交換器4。來自配管53的原水由所述熱交換器4加熱，並被供給至RO裝置6。另外，亦可將熱交換器4中蒸氣冷凝而產生的冷凝水送水至給水槽64。The water in the water supply tank 64 is supplied to the boiler 70 via the pipe 67. The steam generated in the boiler 70 is supplied to the heat exchanger 4 via the pipe 71. The raw water from the piping 53 is heated by the heat exchanger 4 and supplied to the RO device 6. In addition, the condensed water generated by the condensation of the steam in the heat exchanger 4 may be sent to the water supply tank 64.

圖3的另一構成與圖1相同，同一符號表示同一部分。The other configuration of FIG. 3 is the same as that of FIG. 1, and the same symbol indicates the same part.

在圖3中，與加熱泵10連通的熱交換器24、冷凍機20及冷卻塔40的構成為圖1的構成，但亦可如圖2般構成。In FIG. 3, the configurations of the heat exchanger 24, the refrigerator 20, and the cooling tower 40 communicating with the heat pump 10 are the configurations of FIG. 1, but they may also be configured as shown in FIG.

根據此第三實施形態，藉由1台加熱泵10，不僅可對向RO裝置6的給水進行加熱，亦可對向鍋爐70的給水的一部分進行加熱。According to this third embodiment, one heat pump 10 can heat not only the feed water to the RO device 6 but also a part of the feed water to the boiler 70.

而且，可藉由閥51及閥61來切換加熱原水的供給目標，或調整供給量。並且，藉由使用閥51及閥61將加熱泵10的加熱原水優先地供給至RO裝置6，並將加熱原水的餘剩部分設為向鍋爐70的給水，在有效果地削減要被供給至RO裝置6的原水的加溫用的蒸氣的同時，能夠有效地利用由加熱泵10加熱的原水。Moreover, the supply target of the heating raw water can be switched by the valve 51 and the valve 61, or the supply amount can be adjusted. In addition, by using the valve 51 and the valve 61, the heating raw water of the heat pump 10 is preferentially supplied to the RO device 6, and the remaining portion of the heating raw water is used as the feed water to the boiler 70, thereby effectively reducing the supply to the RO The steam for heating the raw water of the device 6 can effectively use the raw water heated by the heat pump 10.

例如，在加熱原水不足RO裝置6的給水的設定溫度（例如25℃）的情況下，以將RO裝置6的給水的全部量設為加熱原水的方式調整閥51、閥61。在加熱原水的全部量超過RO裝置6的給水量的情況下，將加熱原水的餘剩部分送水至給水槽64作為鍋爐給水來使用。在夏季等，加熱原水超過RO裝置6的給水的設定溫度（例如25℃）的情況下，藉由調整閥51、閥61進而閥85，在以使RO裝置6的給水成為設定溫度的方式調整供給至給水槽64的加熱原水與非加熱原水的供給量的同時，將加熱原水的餘剩部分送水至給水槽64。藉由如此，能夠在一年間有效地利用由加熱泵加熱的原水。For example, when the heating raw water is less than the set temperature (for example, 25° C.) of the feed water of the RO device 6, the valves 51 and 61 are adjusted so that the entire amount of the feed water of the RO device 6 is the heating raw water. When the total amount of heated raw water exceeds the feed water amount of the RO device 6, the remaining part of the heated raw water is sent to the feed water tank 64 as boiler feed water. In summer, etc., when the heated raw water exceeds the set temperature of the feed water of the RO device 6 (for example, 25° C.), the valve 51, the valve 61, and the valve 85 are adjusted so that the feed water of the RO device 6 becomes the set temperature. At the same time as the amounts of heated raw water and non-heated raw water supplied to the water supply tank 64, the remaining portion of the heated raw water is sent to the water supply tank 64. With this, the raw water heated by the heat pump can be effectively used for one year.

另外，亦可根據非加熱原水的溫度或者季節來切換加熱原水的供給目標。例如，在非加熱原水的溫度超過了規定溫度的情況下或者在夏季，亦可以將RO裝置6的給水的全部量設為非加熱原水，而將加熱原水全部用作鍋爐給水的方式來調整閥51、閥61及閥85。而且，在非加熱原水的溫度為規定的溫度以下的情況下或者在夏季以外的季節，亦可以將RO裝置6的給水的全部量設為加熱原水，並將加熱原水的餘剩部分用作鍋爐給水的方式來調整閥51、閥61及閥85。In addition, the supply target of heated raw water may be switched according to the temperature or season of unheated raw water. For example, when the temperature of the unheated raw water exceeds a predetermined temperature or in summer, the entire amount of the feed water of the RO device 6 may be set as the unheated raw water, and the whole of the heated raw water may be used as the boiler feed water to adjust the valve. 51. Valve 61 and valve 85. In addition, when the temperature of the unheated raw water is below a predetermined temperature or in seasons other than summer, the entire amount of the feed water of the RO device 6 may be used as the heated raw water, and the remaining part of the heated raw water may be used as the boiler feed water Valve 51, valve 61 and valve 85.

參照圖4對第四實施形態進行說明。The fourth embodiment will be described with reference to FIG. 4.

在圖3的系統中，是將由加熱泵10的冷凝器13加熱的原水直接送水至配管3，但在圖4的系統中，是將來自配管1的原水導入至給水槽80，將給水槽80內的原水經由泵81及配管82而送水至冷凝器13的導熱管13a。自導熱管13a流出的經加熱的原水經由配管83而被返送至給水槽80。如此，給水槽80內的原水的溫度變高。所述給水槽80內的溫度高的原水經由泵84而被送水至配管3。In the system of FIG. 3, the raw water heated by the condenser 13 of the heat pump 10 is directly sent to the piping 3, but in the system of FIG. 4, the raw water from the piping 1 is introduced to the water supply tank 80, and the water supply tank 80 The raw water inside is sent to the heat transfer tube 13a of the condenser 13 via the pump 81 and the pipe 82. The heated raw water flowing out of the heat pipe 13 a is returned to the water supply tank 80 through the pipe 83. In this way, the temperature of the raw water in the water supply tank 80 becomes high. The raw water having a high temperature in the water supply tank 80 is sent to the pipe 3 via the pump 84.

圖4的其他構成與圖3相同，同一符號表示同一部分。根據圖4的系統，亦可獲得與圖3的系統同樣的效果。另外，在圖4中，使原水在給水槽80與冷凝器13中循環，所以可將與圖3時相比加熱為更高的溫度的原水送出至配管3。The other structure of FIG. 4 is the same as that of FIG. 3, and the same symbol indicates the same part. According to the system of FIG. 4, the same effect as the system of FIG. 3 can also be obtained. In addition, in FIG. 4, the raw water is circulated in the water supply tank 80 and the condenser 13, so the raw water heated to a higher temperature than in the case of FIG. 3 can be sent to the pipe 3.

在圖4中，與加熱泵10連通的熱交換器、冷凍機20及冷卻塔40的構成為圖1的構成，但亦可如圖2般構成。In FIG. 4, the configurations of the heat exchanger, the refrigerator 20, and the cooling tower 40 communicating with the heat pump 10 are the configurations of FIG. 1, but they may also be configured as shown in FIG. 2.

設想圖3的裝置，將估算在以下的條件下進行運轉時的蒸氣成本而得的結果示於表1。Assuming the device of FIG. 3, Table 1 shows the results obtained by estimating the steam cost when operating under the following conditions.

[試驗例1] 將加熱泵的加熱原水的全部量用作鍋爐給水，RO給水是利用來自鍋爐的蒸氣（1,228 t/年）將原水自20℃加熱至25℃。[Test Example 1] The entire amount of raw water heated by the heat pump is used as boiler feedwater. RO feedwater uses raw steam from the boiler (1,228 t/year) to heat raw water from 20°C to 25°C.

[試驗例2] 夏季以外的季節將加熱泵的加熱原水的全部量用作RO給水。夏季假設原水有25℃而將原水不加熱來利用。鍋爐給水的全部量使用了未加熱的原水。[Test Example 2] In the seasons other than summer, the entire amount of raw water heated by the heat pump is used as RO feed water. In summer, the raw water is assumed to be 25°C and the raw water is used without heating. Unheated raw water is used for the entire amount of boiler feed water.

[試驗例3] 夏季將加熱泵的加熱原水的全部量用作鍋爐給水，除此以外的季節將加熱泵的加熱原水的全部量用作RO給水。[Test Example 3] In summer, the entire amount of heating raw water of the heat pump is used as boiler feed water, and in other seasons, the entire amount of heating raw water of the heat pump is used as RO feed water.

如表1所示，在藉由根據季節來切換加熱泵的加熱原水的供給目標，有效果地削減要被供給至RO裝置的原水的加溫用的蒸氣的同時，藉由有效果地利用由加熱泵加熱的原水，抑制蒸氣成本成為可能。As shown in Table 1, by switching the supply target of the heating raw water of the heat pump according to the season, while effectively reducing the steam for heating the raw water to be supplied to the RO device, by effectively using the The raw water heated by the heat pump makes it possible to suppress the cost of steam.

參照圖5對第五實施形態進行說明。The fifth embodiment will be described with reference to FIG. 5.

As in the case of FIG. 4, raw water is circulated between the heat pipe 13 a and the water supply tank 80 to be heated.
