However, the pipe 15 may be connected to the pipe 5 on the downstream side of the pure water tank 3. In this case, the divergence point is the take-out portion.
在圖1中,係亦可省略第1熱交換器8B,而並不進行預備冷卻地來僅藉由冷卻手段8A而將鍋爐溢流水一直冷卻至特定溫度。In FIG. 1, the first heat exchanger 8B may be omitted, and the boiler overflow water may be cooled to a specific temperature only by the cooling means 8A without preliminary cooling.
圖2,係為第2實施形態的鍋爐水處理裝置之流程圖。作為純水槽3內之純水之水質維持用的TOC去除裝置,係代替圖1中之RO裝置18而設置有UV(紫外線)氧化裝置25和離子交換裝置26。Fig. 2 is a flow chart showing a boiler water treatment apparatus according to a second embodiment. The TOC removal device for maintaining the water quality of the pure water in the pure water tank 3 is provided with a UV (ultraviolet) oxidation device 25 and an ion exchange device 26 instead of the RO device 18 in Fig. 1 .
作為離子交換樹脂,係以陰離子交換樹脂或混床樹脂為理想。在UV氧化裝置(例如,低壓UV氧化裝置)25中,係對於被處理水(從純水槽3而來之純水)照射UV並將有機物分解為有機酸並且進而分解為CO2 。起因於分解所產生的有機酸、CO2 等,係藉由後段之離子交換裝置26而被去除。通過了離子交換裝置26後的有機物濃度為低之純水,係被從配管19而回送至純水槽3處。As the ion exchange resin, an anion exchange resin or a mixed bed resin is preferred. In a UV oxidizing device (for example, a low-pressure UV oxidizing device) 25, UV is irradiated to the water to be treated (pure water from the pure water tank 3) and the organic matter is decomposed into an organic acid and further decomposed into CO 2 . The organic acid, CO 2 or the like resulting from the decomposition is removed by the ion exchange device 26 in the subsequent stage. The pure water having a low organic matter concentration after passing through the ion exchange unit 26 is returned from the pipe 19 to the pure water tank 3.
在此實施形態中,由於係並未設置有RO裝置18,因此係並未設置有用以將RO濃縮水供給至第1熱交換器8B處之配管20、21。在第1熱交換器8B之低溫流體側處,係通水有從系外所導入之冷卻水。In this embodiment, since the RO device 18 is not provided, the pipes 20 and 21 for supplying the RO concentrated water to the first heat exchanger 8B are not provided. At the low-temperature fluid side of the first heat exchanger 8B, there is a cooling water introduced from the outside of the water.
從發電裝置6之鍋爐而來的鍋爐溢流水,係經由具備有配管7、第1熱交換器8B、冷卻手段8A以及配管9之導入管線,而被送水至復流水除氯裝置10處。其他之構成,係與圖1相同,相同之元件符號,係代表相同之部分。The boiler overflow water from the boiler of the power generation device 6 is sent to the double-flow water removal device 10 via the introduction line including the pipe 7, the first heat exchanger 8B, the cooling means 8A, and the pipe 9. The other components are the same as in FIG. 1, and the same component symbols represent the same parts.
在圖2中,係亦可省略第1熱交換器8B,而並不進行預備冷卻地來僅藉由冷卻手段8A而將鍋爐溢流水一直冷卻至特定溫度。In FIG. 2, the first heat exchanger 8B may be omitted, and the boiler overflow water may be cooled to a specific temperature only by the cooling means 8A without preliminary cooling.
圖1、2,係為本發明之其中一例,本發明係亦可設為圖示以外之形態。1 and 2 are examples of the present invention, and the present invention may be other than the drawings.
以下,針對圖1、2之鍋爐水處理裝置之構成機器的合適例、功能等作說明。Hereinafter, suitable examples, functions, and the like of the constituent devices of the boiler water treatment apparatus of Figs. 1 and 2 will be described.
1) 前置處理裝置1 前置處理裝置1,例如,係對於工業用水(都市水、地下水等)等之原水,而依序進行冷凝處理、固液分離(沈澱分離或加壓上浮分離等)、雙層過濾,之後,進行除氯處理(由陽離子交換樹脂塔、除碳酸塔、陰離子交換樹脂塔、混床樹脂塔、電性除氯裝置等所致之處理),藉由此,來製造出純水。1) Pre-treatment unit 1 The pre-processing unit 1 is, for example, condensing treatment or solid-liquid separation (precipitation separation or pressurized floating separation, etc.) for raw water such as industrial water (urban water, groundwater, etc.). , double-layer filtration, followed by dechlorination treatment (process by cation exchange resin column, decarbonation column, anion exchange resin column, mixed bed resin column, electric dechlorination device, etc.), thereby manufacturing Pure water.
2) 純水槽3 在純水槽3中,係儲存有藉由前置處理所製造出之純水,並進行有水質及水量之調整。2) Pure water tank 3 In the pure water tank 3, the pure water produced by the pretreatment is stored, and the water quality and the water quantity are adjusted.
3) TOC去除手段 當在工業用水等之原水中所含有之TOC濃度為高的情況時,係會有難以藉由前置處理來將TOC濃度一直降低至特定以下(例如未滿100ppb)之濃度的情況。若是TOC濃度成為100ppb以上,則對於鍋爐所造成的負擔係變大,並會有在將來而發生故障之虞。又,依存於季節或氣候等,水溫係會有所變動(例如5~35℃)。若是水溫成為15℃以下,則對於發電用鍋爐所造成的負擔係變大,燃料使用量係變多。3) TOC removal means When the concentration of TOC contained in raw water such as industrial water is high, there is a possibility that it is difficult to reduce the TOC concentration to a specific value (for example, less than 100 ppb) by pretreatment. Case. If the TOC concentration is 100 ppb or more, the burden on the boiler will increase, and there will be a failure in the future. Further, depending on the season or climate, the water temperature may vary (for example, 5 to 35 ° C). When the water temperature is 15° C. or less, the burden on the boiler for power generation is increased, and the amount of fuel used is increased.
因此,係以使純水槽3內之純水的TOC會恆常被維持於特定值以下(例如100ppb以下)的方式,來將從構成純水供給管線之純水槽3所分離取出之純水,藉由以RO裝置18或者是以UV氧化裝置25以及離子交換裝置26所構成之TOC去除手段,來進行TOC去除處理。Therefore, the pure water which is separated from the pure water tank 3 constituting the pure water supply line is maintained so that the TOC of the pure water in the pure water tank 3 is constantly maintained at a specific value or less (for example, 100 ppb or less). The TOC removal process is performed by the RO device 18 or the TOC removal means constituted by the UV oxidation device 25 and the ion exchange device 26.
藉由作為TOC去除手段而使用物理化學性手段,係能夠對於雜質殘留在處理水中的情形作抑制。藉由將TOC去除手段設置在從純水供給管線所分歧出來之TOC去除管線處,係成為能夠例如並不被伴隨著膜逆洗所導致之通水停止所影響地來進行與純水供給管線相異之控制或維修。TOC去除手段,係可藉由追加之工程來容易地設置在已設置之鍋爐供水裝置處。By using a physicochemical means as a TOC removing means, it is possible to suppress the case where impurities remain in the treated water. By setting the TOC removal means at the TOC removal line branched from the pure water supply line, it is possible to carry out the pure water supply line, for example, without being affected by the stoppage of water caused by the backwashing of the membrane. Different control or repair. The TOC removal means can be easily installed at the boiler water supply unit that has been set up by additional work.
係亦可設置對於藉由TOC除去手段而進行TOC去除處理之純水的取出部(在圖1、2中,係為純水槽3)或較其更上游側之純水供給管線(在圖1、2中,係為配管2)的純水之TOC濃度之TOC濃度測定手段,並當此TOC濃度測定手段之測定值為特定值以上時,開始由TOC去除手段所致之TOC之去除處理。It is also possible to provide a pure water take-out portion (pure water tank 3 in FIGS. 1 and 2) or a pure water supply line on the upstream side of the TOC removal treatment by the TOC removal means (in FIG. 1). In the second, the TOC concentration measuring means of the TOC concentration of the pure water of the pipe 2) is used, and when the measured value of the TOC concentration measuring means is a specific value or more, the TOC removal process by the TOC removing means is started.
於此情況,例如,係亦可構成為使TOC濃度測定手段與幫浦17相互連動,若是TOC濃度測定手段之測定值成為了特定值以上,則使幫浦17動作,並對於TOC去除手段供給水而進行TOC去除處理。亦可構成為在配管15處設置開閉閥,並使此開閉閥與TOC濃度測定手段相互連動,而在TOC濃度測定手段之測定值成為了特定值以上時,將開閉閥設為開,並對於TOC去除手段供給純水而進行TOC去除處理。當TOC濃度測定手段之測定值成為了較特定值而更低的情況時,係使幫浦17停止,或者是將開閉閥設為閉,而停止對於TOC去除手段之純水之供給。In this case, for example, the TOC concentration measuring means and the pump 17 may be interlocked with each other. When the measured value of the TOC concentration measuring means is equal to or greater than a specific value, the pump 17 is operated and supplied to the TOC removing means. The TOC removal treatment is performed with water. In addition, an opening/closing valve may be provided in the piping 15, and the opening and closing valve and the TOC concentration measuring means may be interlocked with each other. When the measured value of the TOC concentration measuring means is equal to or greater than a specific value, the opening and closing valve is opened, and The TOC removal means supplies pure water to perform TOC removal processing. When the measured value of the TOC concentration measuring means is lower than a specific value, the pump 17 is stopped, or the opening and closing valve is closed, and the supply of pure water to the TOC removing means is stopped.
除了基於TOC濃度測定手段之測定值來針對對於TOC去除手段之純水之供給的有無進行控制以外,亦可針對對於TOC去除手段之純水的供給量作控制。例如,係亦可構成為使TOC濃度測定手段與幫浦17相互連動,若是TOC濃度測定手段之測定值成為了特定值以上,則提高幫浦17之旋轉數,並使對於TOC去除手段之純水供給量增加,而使進行TOC去除處理之純水量增加。亦可構成為在配管15處設置流量調整閥,並使此流量調整閥與TOC濃度測定手段相互連動,若是TOC濃度測定手段之測定值成為了特定值以上,則增大流量調整閥之開度並使對於TOC去除手段之純水供給量增加,而使進行TOC去除處理之純水量增加。當TOC濃度測定手段之測定值成為了較特定值而更低的情況時,係將幫浦17之旋轉數降低,或者是將流量調整閥之開度縮小,而將對於TOC去除手段之純水供給量減少。In addition to controlling the supply of pure water to the TOC removal means based on the measured value of the TOC concentration measuring means, the supply amount of pure water to the TOC removing means can be controlled. For example, the TOC concentration measuring means may be interlocked with the pump 17, and if the measured value of the TOC concentration measuring means is equal to or greater than a specific value, the number of rotations of the pump 17 is increased, and the TOC removal means is pure. The amount of water supplied increases, and the amount of pure water subjected to the TOC removal treatment increases. Further, a flow rate adjustment valve may be provided in the piping 15, and the flow rate adjustment valve and the TOC concentration measuring means may be interlocked with each other. If the measured value of the TOC concentration measuring means is equal to or greater than a specific value, the opening of the flow rate adjusting valve is increased. The amount of pure water supplied to the TOC removal means is increased, and the amount of pure water subjected to the TOC removal treatment is increased. When the measured value of the TOC concentration measuring means becomes lower than a specific value, the number of rotations of the pump 17 is lowered, or the opening degree of the flow regulating valve is reduced, and the pure water for the TOC removing means is used. The supply is reduced.
藉由基於TOC濃度測定手段之測定值來針對對於TOC去除手段之純水之供給的有無或供給量進行控制,係能夠藉由TOC去除手段來對於必要量之純水進行處理,而能夠降低關連於純水之TOC去除處理的成本。By controlling the presence or absence of the supply of pure water to the TOC removal means or the amount of supply based on the measured value of the TOC concentration measuring means, it is possible to reduce the amount of pure water by the TOC removal means, thereby reducing the correlation. The cost of the TOC removal process in pure water.
對於TOC去除手段之純水之供給的有無或者是供給量之增減之控制,係可藉由被輸入有TOC濃度測定手段之TOC濃度之測定值並基於此測定值來輸出對於幫浦或閥之控制訊號的控制裝置,來以自動控制而進行之。The presence or absence of the supply of pure water by the TOC removal means or the control of the increase or decrease of the supply amount can be outputted to the pump or valve based on the measured value of the TOC concentration to which the TOC concentration measuring means is input and based on the measured value. The control device of the control signal is controlled by automatic control.
4) 作為發電裝置6,係存在有具備高壓鍋爐之IPP發電裝置等的各種之裝置。4) As the power generation device 6, there are various devices such as an IPP power generation device including a high-pressure boiler.
5) 鍋爐溢流水排出管線~復流水除氯手段~復流水回送管線 鍋爐蒸氣之冷凝水,一般而言係為高溫(例如70~97℃),在從鍋爐而作為鍋爐溢流水來排出之後,係在藉由冷卻手段8A(密閉冷卻塔、熱交換器等)而冷卻至20~40℃程度之後,被供給至復流水除氯裝置10。5) Boiler overflow water discharge line - double-flow water dechlorination means - double-flow water return line Boiler vapor condensate, generally high temperature (for example, 70 ~ 97 ° C), after being discharged from the boiler as boiler overflow water After cooling to 20 to 40 ° C by the cooling means 8A (sealed cooling tower, heat exchanger, etc.), it is supplied to the double-flow water removal apparatus 10.
在圖1、2中,作為復流水除氯裝置10,雖係例示有串聯2段RO處理→電性除氯,但是,只要身為能夠進行除氯處理之物理化學性手段,則係並未特別作限定。In FIGS. 1 and 2, the reflowing water removal apparatus 10 is exemplified by two-stage RO treatment in series → electrical dechlorination, but as long as it is a physicochemical means capable of performing dechlorination treatment, Special limitation.
6) 第1熱交換器8B 如同圖1一般,當作為TOC去除手段而使用有RO裝置18的情況時,由於係被排出有常溫程度(5~35℃)之RO濃縮水,因此,係將此RO濃縮水通水至被設置在冷卻手段8A之前段的第1熱交換器8B處,並與鍋爐溢流水進行熱交換,而將鍋爐溢流水預先冷卻至50~70℃程度。藉由此,來減輕被設置在復流水除氯裝置10之前段的冷卻手段8A之負擔。6) When the RO unit 18 is used as the TOC removal means, the first heat exchanger 8B is generally RO-concentrated water at a normal temperature (5 to 35 ° C). This RO concentrated water is passed to the first heat exchanger 8B provided in the front stage of the cooling means 8A, and exchanges heat with the boiler overflow water, and the boiler overflow water is previously cooled to about 50 to 70 °C. Thereby, the burden of the cooling means 8A provided in the preceding stage of the double-flow water removing apparatus 10 is alleviated.
7) 第2熱交換器16 當純水槽3之水溫係易於降低至特定值以下(例如15℃以下)的情況時,係將TOC去除手段之供水在第2熱交換器16處而與溫水進行熱交換並加溫。藉由此,係能夠以TOC去除手段來有效率地進行TOC之去除。若是將純水槽3之水溫設為例如維持於20~35℃,則係能夠減輕IPP發電設備之高壓鍋爐的負擔。7) When the water temperature of the pure water tank 3 is easily reduced to a specific value or less (for example, 15 ° C or lower), the water supply of the TOC removal means is at the second heat exchanger 16 and is warmed. The water is heat exchanged and heated. Thereby, the TOC removal can be efficiently performed by the TOC removal means. When the water temperature of the pure water tank 3 is maintained at, for example, 20 to 35 ° C, the burden on the high-pressure boiler of the IPP power generation facility can be reduced.
亦可構成為:對於純水供給管線(配管2、純水槽3、配管5等)或TOC去除管線(配管15、19等)之中的水溫進行測定,並以當測定值成為特定值以下之低溫時,對於第2熱交換器16供給溫水的方式來對於閥進行切換並進行由本機構所致之升溫的方式,來進行控制。亦可構成為基於水溫測定值來調整對於第2熱交換器16之供給流量的方式,來進行流量控制。藉由此,鍋爐供水之水溫係被維持於特定之範圍,對於鍋爐所造成的負擔係被維持於一定之範圍內。 [實施例]The water temperature in the pure water supply line (pipe 2, pure water tank 3, piping 5, etc.) or TOC removal line (pipes 15, 19, etc.) may be measured, and the measured value may be a specific value or less. At the time of the low temperature, the second heat exchanger 16 is supplied with warm water so that the valve is switched and the temperature rise by the mechanism is performed. The flow rate control may be performed by adjusting the supply flow rate to the second heat exchanger 16 based on the measured value of the water temperature. As a result, the water temperature of the boiler water supply is maintained within a specific range, and the burden on the boiler is maintained within a certain range. [Examples]
