Description

本発明は、プラントから排出される高い温度の冷却水を自然冷却させ、台風や津波による異常な海水面の上昇がある時、上昇した海水面が取水池および排水池の内部の水面の高さに影響を及ぼすのを防止し、有事の際に汚染水の漏出を遮断することができ、取水・排水池の冷却機能を活用することで取水・排水量を減少させることができるため、取水・排水施設の規模を縮小することができ、建設費および維持管理費などの節減効果があり、排出水の量を減少させることにより、排水流域の海洋生態系の環境破壊を減少させることができる通水管を用いた取水池および排水池を備えたプラント冷却施設に関するものである。   The present invention naturally cools high-temperature cooling water discharged from a plant, and when there is an abnormal sea level rise due to a typhoon or tsunami, the sea level that has risen is the height of the water level inside the intake pond and drainage pond. Water intake and drainage can be reduced by using the cooling function of the water intake and drainage basin. Water pipes that can reduce the scale of facilities, reduce construction costs and maintenance costs, and reduce the environmental damage to the marine ecosystem in the drainage basin by reducing the amount of discharged water The present invention relates to a plant cooling facility equipped with a water intake pond and a drainage basin.

従来のプラント取水・排水施設は、図１に示されるように、防波堤本体と、テトラポットとから構成された従来の防波堤１０が海岸に沿って配置され、防波堤の一部に開口部１３を設け、海水を外海から取水路に流入させることにより、流入した海水をプラント１１設備の冷却水として使用する。プラント設備に使用された冷却水は排水路１４に出て、排水路の開口部１５を介して外海に排出される。   As shown in FIG. 1, a conventional plant intake / drainage facility has a conventional breakwater 10 composed of a breakwater body and a tetrapot arranged along the coast, and an opening 13 is provided in a part of the breakwater. By flowing seawater from the open sea into the intake channel, the seawater that flows in is used as cooling water for the plant 11 equipment. The cooling water used for the plant equipment exits to the drainage channel 14 and is discharged to the open sea through the opening 15 of the drainage channel.

このような従来のプラント取水・排水施設の防波堤は、波が取水・排水口に直接的な影響を及ぼすのを防止するだけであり、開口部に統制設備がないため、浮遊物や水中生物の流入に伴う処理問題が発生することがある。   Such breakwaters in conventional plant intake and drainage facilities only prevent waves from directly affecting the intake and drainage outlets, and because there are no control facilities at the opening, Processing problems associated with inflow may occur.

また、従来のプラント取水・排水施設では、高い温度の表面水を取水してプラント設備に冷却水として供給するため、冷却効率が低下し、プラントに使用されて排出された高い温度の冷却水と油などの汚染物が排出水流域に直に排出され、海洋生態系を汚染させる。また、遮断施設がないため、台風や津波による異常な海水面の上昇がある時にも、上昇した海水面が開口部１３に入ってきて取水路および排水路の内部の水面の高さにそのまま影響を及ぼし、取水・排水に問題が発生する。   In addition, in conventional plant water intake / drainage facilities, since high temperature surface water is taken and supplied to the plant equipment as cooling water, the cooling efficiency decreases, and the high temperature cooling water discharged from the plant is discharged. Pollutants such as oil are discharged directly into the effluent basin, polluting the marine ecosystem. In addition, since there is no blocking facility, even when there is an abnormal sea level rise due to a typhoon or tsunami, the sea level that has risen enters the opening 13 and directly affects the water level inside the intake and drainage channels. Cause problems with water intake and drainage.

本発明は、上記の従来の問題を解決するために、通水管を用いた取水池および排水池を備え、これに追加的に取水池および排水池を連結する連結管を備えたプラント冷却施設を提供することを目的とする。   In order to solve the above-described conventional problems, the present invention includes a plant cooling facility provided with a water intake pond and a drainage basin using a water pipe, and additionally with a connection pipe for connecting the water intake basin and the water drainage basin. The purpose is to provide.

上記の目的を達成するために、本発明は、外部から流体が流入することができ、プラントに連結される取水池と、外部に流体を放出させることができ、プラントに連結される排水池と、前記取水池と前記排水池とを連結する連結管と、前記取水池と外部とを連結させる取水通水管と、前記排水池と外部とを連結させる排水通水管とを含むプラント冷却施設を提供する。   In order to achieve the above object, the present invention provides an intake pond that allows fluid to flow in from the outside and is connected to the plant, and a drainage pond that can discharge fluid to the outside and is connected to the plant. A plant cooling facility including a connection pipe connecting the intake pond and the drainage basin, a water intake pipe connecting the intake pond and the outside, and a drainage water pipe connecting the drainage pond and the outside To do.

本発明では、前記取水通水管および排水通水管は、１つ以上配置され、前記取水通水管および排水通水管を介して流体の流入および流出が可能であってもよい。   In the present invention, one or more intake water pipes and drain water pipes may be arranged, and fluid may be allowed to flow in and out through the intake water pipe and drain water pipe.

本発明では、前記連結管は、１つ以上配置され、前記連結管を介して流体の流入および流出が可能であってもよい。   In the present invention, one or more connecting pipes may be arranged, and fluid may be allowed to flow in and out through the connecting pipe.

本発明では、前記取水通水管および排水通水管のうちの１つ以上は、開閉を自動または手動で調整する開閉装置をさらに含むこともできる。   In the present invention, one or more of the water intake water pipe and the drain water pipe may further include an opening / closing device that adjusts opening / closing automatically or manually.

本発明では、前記取水通水管および排水通水管のうちの１つ以上には、チェックバルブが形成されてもよい。   In the present invention, a check valve may be formed in one or more of the intake water conduit and the drain water conduit.

本発明では、前記取水通水管および排水通水管のうちの１つ以上の端部は、下方向に傾斜して形成されてもよい。   In the present invention, one or more ends of the water intake water conduit and the drain water conduit may be formed to be inclined downward.

本発明では、前記取水通水管および排水通水管のうちの１つ以上には、異物の流入を遮断する遮断網が形成されてもよい。   In the present invention, a blocking net that blocks inflow of foreign matter may be formed in one or more of the intake water conduit and the drain water conduit.

本発明のプラント冷却施設は、水深の深い所に取水・排水口を設け、表面水より温度の低い冷却水を取水することができ、浮遊物が流入しない。   In the plant cooling facility of the present invention, a water intake / drain port is provided at a deep water depth, and cooling water having a temperature lower than that of the surface water can be taken in, so that floating substances do not flow in.

また、本発明のプラント冷却施設は、通水管に開閉装置を設け、取水・排水量の調整が可能なため、津波のような急激な外部環境の変化にも取水・排水池の水位を適正な高さに調整することができ、原発事故またはプラントの誤作動で取水池および排水池が汚染する場合、汚染水が外海に排出されるのを遮断する効果を奏することができる。   In addition, the plant cooling facility of the present invention is provided with an open / close device in the water pipe, and the intake and drainage volume can be adjusted, so that the water level of the intake and drainage pond can be raised to an appropriate level even when there is a sudden change in the external environment such as a tsunami. When the intake pond and the drainage pond are contaminated due to a nuclear accident or a malfunction of the plant, the effect of blocking the discharge of the contaminated water to the open sea can be achieved.

また、本発明のプラント冷却施設は、通水管の端部が下方傾斜し、遮断網が設けられていて、異物および海洋生物の流入を遮断することができる。   In the plant cooling facility of the present invention, the end of the water pipe is inclined downward, and a shut-off net is provided to block the inflow of foreign matter and marine organisms.

また、本発明のプラント冷却施設は、取水池および排水池を形成し、高い温度の排出冷却水が自然冷却可能であり、温度が低下した冷却水は排出されても排出流域の生態系が破壊されず、取水池と排水池とを連結する連結管を介して取水池に循環し、新たな冷却水の流入および放出がなくてもプラントに冷却水を供給することができる。   In addition, the plant cooling facility of the present invention forms intake ponds and drainage ponds, and high-temperature exhaust cooling water can be naturally cooled. Even if cooling water with a lowered temperature is discharged, the ecosystem in the discharge basin is destroyed. Instead, it circulates to the intake pond via the connecting pipe connecting the intake pond and the drainage basin, and the cooling water can be supplied to the plant without the inflow and discharge of new cooling water.

また、本発明のプラント冷却施設では、取水池および排水池の循環機能で取水・排水量が大幅に減少することにより、既存の取水・排水施設に比べて規模の縮小が可能なため、建設費および維持管理費などを節減させる効果を奏することができる。   Moreover, in the plant cooling facility of the present invention, since the intake / drainage amount is significantly reduced by the circulation function of the intake pond and the drainage pond, the scale can be reduced as compared with the existing intake / drainage facility. The effect of reducing maintenance costs can be achieved.

以下、本発明の属する技術分野における通常の知識を有する者が本発明を容易に実施できるように説明するために、本発明の最も好ましい実施形態を、添付した図面を参照して説明する。   DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the most preferred embodiments of the present invention will be described with reference to the accompanying drawings in order to describe those skilled in the art to which the present invention can easily practice the present invention.

図２は、本発明のプラント冷却施設の側面図を概念的に示す。海岸から相当距離離れ、水深の深い所に設けられた取水口１００に流入した流体は、取水通水管１０１を介して取水池１１０に貯蔵され、貯蔵された流体は、ポンプ１０２によってプラント１０３に流入して使用される。以後、プラント１０３で使用された流体は、配水管を介して、規模が大きくかつ新設された排水池１１１に貯蔵された後、排水通水管１０６を介して排水口１０５に排出される。   FIG. 2 conceptually shows a side view of the plant cooling facility of the present invention. The fluid that has flowed into the intake 100 provided at a deep distance from the coast is stored in the intake basin 110 via the intake water pipe 101, and the stored fluid flows into the plant 103 by the pump 102. Used. Thereafter, the fluid used in the plant 103 is stored in a large and newly constructed drainage basin 111 via a water distribution pipe and then discharged to a drainage port 105 via a drainage water pipe 106.

本発明のプラント冷却施設は、取水通水管１０１または排水通水管１０６、または取水通水管１０１および排水通水管１０６に開閉装置が設けられていて、取水池および排水池に冷却水を貯蔵することが可能であり、必要な時に適切に使用したり、排出することができる。また、本発明のプラント冷却施設は、プラントの誤作動で取水池および排水池の冷却水が汚染する場合、汚染した冷却水が外部に漏出するのを遮断することができ、取水池および排水池の冷却水を循環させることで、相当期間貯蔵された冷却水でプラントを稼働することができる。   In the plant cooling facility of the present invention, the intake water pipe 101 or the drain water pipe 106, or the intake water pipe 101 and the drain water pipe 106 is provided with an opening / closing device, and the cooling water can be stored in the intake pond and the drain pond. Yes, it can be used and discharged properly when needed. Moreover, the plant cooling facility of the present invention can block the leakage of the contaminated cooling water to the outside when the cooling water of the intake pond and the drainage pond is contaminated due to a malfunction of the plant. By circulating the cooling water, the plant can be operated with the cooling water stored for a considerable period of time.

また、前記取水池１１０および排水池１１１は、連結通路である連結管１１２で連結されており、この連結管は、前記開閉装置がある通水管であって、取水池１１０および排水池１１１の流体を循環させることができる。   In addition, the intake basin 110 and the drainage basin 111 are connected by a connection pipe 112 that is a connection passage, and this connection pipe is a water pipe having the switchgear, and the fluid in the intake basin 110 and the drainage basin 111. Can be circulated.

したがって、本発明のプラント冷却施設は、取水時より通常３〜４℃高い状態で排出される冷却水を排水池に貯蔵し、風や蒸発などで自然冷却させる。したがって、本発明のプラント冷却施設は、冷却水の温度を維持管理することにより、温度の低い冷却水を排出し、排水口周辺の海洋生態系の破壊を防止することができ、取水水量を大幅に減少させることにより、取水・排水施設が縮小され、建設費および維持管理費などの節減効果を奏することができる。例えば、３℃上昇した排出冷却水の温度を低下させるのに、取水量が１時間あたり３００ｌ必要であったものを、自然冷却によって２℃低下させることができれば、冷却用取水量は１時間あたり１００ｌと約１／３に減少させることができ、これは、取水・排水施設の規模も１／３に縮小できることを意味する。   Therefore, the plant cooling facility of the present invention stores the cooling water discharged in a state that is usually 3 to 4 ° C. higher than that at the time of water intake in the drainage basin, and naturally cools it with wind or evaporation. Therefore, the plant cooling facility according to the present invention can maintain the temperature of the cooling water to discharge the cooling water having a low temperature and prevent the marine ecosystem around the drain outlet from being destroyed, thereby greatly increasing the amount of water taken. By reducing the amount of water, the water intake and drainage facilities can be reduced, and the construction and maintenance costs can be saved. For example, if the amount of water intake needed to be 300 liters per hour to reduce the temperature of the discharged cooling water increased by 3 ° C. can be reduced by 2 ° C. by natural cooling, the amount of water intake for cooling can be reduced per hour. 100 l, which can be reduced to about 1/3, which means that the scale of intake and drainage facilities can be reduced to 1/3.

図３は、本発明のプラント冷却施設の第１実施形態の平面を示す。取水池２００と排水池２０１は、陸上に建設することも可能であるが、海岸に防波堤２１０で取水池および排水池を形成した後、外部と通水管２２０、２３０で連結し、流体を流入または放出することもできる。取水池と排水池とを連結する連結管２４０は、陸地に設けることも可能であり、防波堤の下部に建設することも可能である。   FIG. 3 shows a plan view of the first embodiment of the plant cooling facility of the present invention. The intake basin 200 and the drainage basin 201 can be constructed on land. However, after the intake basin and the drainage basin are formed on the coast by the breakwater 210, the intake basin 200 and the drainage basin 201 are connected to the outside by the water pipes 220 and 230 to flow in or It can also be released. The connecting pipe 240 that connects the intake pond and the drainage pond can be provided on land or can be constructed below the breakwater.

既存の、外海に延びる取水通水管、排水通水管の設置は水中工事であるため、工事費が非常に高かった。しかし、本発明は、自然冷却機能により施設規模の縮小が可能なため、建設費、建設期間、維持管理費を大幅に節減することができる。   Since the installation of existing intake and drainage pipes extending to the open sea is underwater construction, the construction costs were very high. However, since the facility scale can be reduced by the natural cooling function, the present invention can greatly reduce the construction cost, construction period, and maintenance cost.

図４は、本発明のプラント冷却施設の第２実施形態を示す。図１に示された従来の防波堤１０の間の開口部１３、１５に本発明の通水管を備えた防波堤２０を設け、閉鎖型取水路４０および排水路４１の形態に変形することにより、高い温度の排出冷却水を自然冷却させ、台風や津波による異常な海水面の上昇がある時、上昇した海水面が取水路および排水路の内部の水面の高さに影響を及ぼすのを防止し、有事の際に汚染水の漏出を遮断することができる。   FIG. 4 shows a second embodiment of the plant cooling facility of the present invention. By providing the breakwater 20 provided with the water pipe of the present invention in the openings 13 and 15 between the conventional breakwater 10 shown in FIG. 1, the shape is changed to a closed intake channel 40 and a drainage channel 41. The cooling water of the temperature is naturally cooled, and when there is an abnormal sea level rise due to a typhoon or tsunami, the sea level that has risen is prevented from affecting the water level inside the intake and drainage channels, In the event of an emergency, the leakage of contaminated water can be blocked.

取水路４０と排水路４１との間には、開閉装置が備えられた連結管４２を設け、排水池の冷却水を取水池に循環させることにより、新たな冷却水の流入および放出がなくてもプラントに冷却水を供給することができる。また、取水および排水の水量が大幅に減少することにより、既存の冷却施設に比べて維持管理費などの節減効果がある。   Between the intake channel 40 and the drainage channel 41, a connecting pipe 42 provided with an opening / closing device is provided, and the cooling water in the drainage basin is circulated to the water basin so that new cooling water does not flow in and out. Can also supply cooling water to the plant. In addition, a significant reduction in water intake and drainage results in savings such as maintenance costs compared to existing cooling facilities.
