Description

本発明は、復水脱塩装置の再生装置が備える薬液希釈装置の設置個所に設けられた、排水升用の蓋部材に関する。   The present invention relates to a lid member for a drainage tub provided at an installation location of a chemical solution dilution device provided in a regenerator of a condensate demineralizer.

発電所においては、タービンを駆動させた後の蒸気を冷却して復水を生成し、この復水を加熱して再び蒸気とし、この蒸気で再び発電タービンを駆動させるサイクルが繰り返される。復水は、各種の不純物イオンやクラツドで汚染されている可能性があるので、これら汚染物を除去するために、イオン交換樹脂を用いた復水脱塩装置が用いられている。
復水脱塩装置では、硫酸や苛性ソーダといった薬品を用いて、イオン交換樹脂の再生が行われる。硫酸や苛性ソーダは、タンクローリから貯蔵装置に一旦貯蔵された後、希釈装置で希釈されてからイオン交換樹脂の再生に用いられる（例えば特許文献１参照）。 In the power plant, the steam after driving the turbine is cooled to generate condensate, and this condensate is heated again to become steam, and the cycle of driving the power generation turbine again with this steam is repeated. Since condensate may be contaminated with various impurity ions and cladding, a condensate demineralizer using an ion exchange resin is used to remove these contaminants.
In the condensate demineralizer, the ion exchange resin is regenerated using chemicals such as sulfuric acid and caustic soda. Sulfuric acid and caustic soda are once stored in a storage device from a tank truck, and then diluted with a dilution device before being used for regeneration of an ion exchange resin (see, for example, Patent Document 1).

希釈装置において、時折、付属する機器の分解修理や内部点検が行われる。その際の事前準備として、希釈装置に付着した薬品のブロー（除去、洗浄）が実施される。ブローされた薬品は、希釈装置が設置されている個所の床部に設けられた排水升に流出される。排水升には、従来、グレーチングの蓋部材が取り付けられている。   In the diluting device, the attached equipment is occasionally repaired and inspected internally. As a preliminary preparation at that time, blowing (removal, washing) of the chemical adhering to the diluting device is performed. The blown chemical flows out into a drainage basin provided on the floor where the diluter is installed. Conventionally, a grating lid member is attached to the drainage basin.

A plate-like member having a waste liquid inflow hole to which a pipe into which a waste liquid containing a chemical solution flows is connected, and a pipe connected to the lower surface side of the plate-like member in the through hole and provided with a drain trap. Provided is a drainage lid member.

前記板状部材は、前記廃液流入用穴より前記排水升に流入される前記薬液に対して耐性を有する材料で製造されていることが好ましい。   It is preferable that the plate-like member is made of a material having resistance to the chemical liquid flowing into the drainage basin through the waste liquid inflow hole.

前記板状部材は、透明であることが好ましい。   The plate-like member is preferably transparent.

前記板状部材は、アクリル板であることが好ましい。   The plate member is preferably an acrylic plate.

以下、本発明の実施形態について説明する。本実施形態は、復水脱塩装置１００の再生装置１０１が備える薬液希釈装置の設置個所に設けられた、排水升２用の蓋部材１０に関するものである。   Hereinafter, embodiments of the present invention will be described. The present embodiment relates to a lid member 10 for a drainage tub 2 provided at an installation location of a chemical liquid diluting device provided in a regenerator 101 of a condensate demineralizer 100.

復水脱塩装置１００は、タービンを駆動し、復水器で凝縮された復水内にイオンとして溶け込んでいる不純物を、イオン交換樹脂によって除去し、発電設備で使用する純水を製造する装置である。
図１は、復水脱塩装置１００及びその再生装置１０１を示す図である。再生装置１０１は、復水脱塩装置１００に接続された陽イオン交換樹脂再生塔１０２及び陰イオン交換樹脂再生塔１０３を備える。 The condensate demineralizer 100 drives the turbine and removes impurities dissolved as ions in the condensate condensed by the condenser by using an ion exchange resin to produce pure water for use in power generation equipment. It is.
FIG. 1 is a diagram showing a condensate demineralizer 100 and a regenerator 101 thereof. The regeneration apparatus 101 includes a cation exchange resin regeneration tower 102 and an anion exchange resin regeneration tower 103 connected to the condensate demineralization apparatus 100.

陽イオン交換樹脂再生塔１０２には硫酸希釈装置１０４ａが接続されている。硫酸希釈装置１０４ａには、硫酸貯蔵装置１０５が接続され、硫酸貯蔵装置１０５にはタンクローリから濃硫酸が供給される。
陰イオン交換樹脂再生塔１０３には苛性ソーダ希釈装置１０４ｂが接続されている。苛性ソーダ希釈装置１０４ｂには、苛性ソーダ貯蔵装置１０７が接続され、苛性ソーダ貯蔵装置１０７にはタンクローリから苛性ソーダが供給される。 A sulfuric acid diluting device 104 a is connected to the cation exchange resin regeneration tower 102. A sulfuric acid storage device 105 is connected to the sulfuric acid dilution device 104a, and concentrated sulfuric acid is supplied to the sulfuric acid storage device 105 from a tank truck.
A caustic soda dilution apparatus 104b is connected to the anion exchange resin regeneration tower 103. A caustic soda storage device 107 is connected to the caustic soda dilution device 104b, and the caustic soda storage device 107 is supplied with caustic soda from a tank truck.

復水脱塩装置１００にはイオン交換樹脂が陽イオン交換樹脂と陰イオン交換樹脂が混合状態で充填されている。イオン交換樹脂を再生する場合、まず、復水脱塩装置１００内の混合状態のイオン交換樹脂を陽イオン交換樹脂再生塔１０２へ移送し、陽イオン交換樹脂と陰イオン交換樹脂との比重差を利用し分離する。分離した陰イオン交換樹脂は、陰イオン交換樹脂再生塔１０３へ移送される。   The condensate demineralizer 100 is filled with an ion exchange resin mixed with a cation exchange resin and an anion exchange resin. When regenerating the ion exchange resin, first, the mixed ion exchange resin in the condensate demineralizer 100 is transferred to the cation exchange resin regeneration tower 102, and the specific gravity difference between the cation exchange resin and the anion exchange resin is determined. Use and separate. The separated anion exchange resin is transferred to the anion exchange resin regeneration tower 103.

硫酸貯蔵装置１０５から移送された硫酸は、硫酸希釈装置１０４ａにより所定値まで希釈された後、陽イオン交換樹脂再生塔１０２へ供給される。これにより、陽イオン交換樹脂再生塔１０２内の陽イオン交換樹脂の再生が行われる。   The sulfuric acid transferred from the sulfuric acid storage device 105 is diluted to a predetermined value by the sulfuric acid diluting device 104 a and then supplied to the cation exchange resin regeneration tower 102. Thereby, the cation exchange resin in the cation exchange resin regeneration tower 102 is regenerated.

苛性ソーダ貯蔵装置１０７から移送された苛性ソーダは、苛性ソーダ希釈装置１０４ｂで希釈された後、陰イオン交換樹脂再生塔１０３へ供給される。これにより、陰イオン交換樹脂再生塔１０３内の陰イオン交換樹脂の再生が行われる。   The caustic soda transferred from the caustic soda storage device 107 is diluted by the caustic soda dilution device 104 b and then supplied to the anion exchange resin regeneration tower 103. Thereby, the anion exchange resin in the anion exchange resin regeneration tower 103 is regenerated.

ここで、硫酸希釈装置１０４ａや苛性ソーダ希釈装置１０４ｂは、時折、分解修理や内部点検が行われる。その際の事前準備において、硫酸希釈装置１０４ａや苛性ソーダ希釈装置１０４ｂに付着している薬品の除去（ブロー）が行われる。
硫酸希釈装置１０４ａや苛性ソーダ希釈装置１０４ｂは、周囲に薬品が飛散しないように、例えば壁部で覆われている。薬品を飛ばすための水等がブローされると、薬品は、洗浄用の水とともに硫酸希釈装置１０４ａや苛性ソーダ希釈装置１０４ｂのそれぞれから延びる排水管を通って、それぞれの排水升内に流出される。
なお、硫酸希釈装置１０４ａ及び苛性ソーダ希釈装置１０４ｂについて、それぞれから延びる排水管や排水弁の構成は同様であるので、以下、共通して希釈装置１０４、排水管３、排水升２として説明する。 Here, the sulfuric acid diluting device 104a and the caustic soda diluting device 104b are occasionally subjected to disassembly and repair and internal inspection. In advance preparation at that time, removal (blowing) of chemicals adhering to the sulfuric acid diluting device 104a and the caustic soda diluting device 104b is performed.
The sulfuric acid diluting device 104a and the caustic soda diluting device 104b are covered with, for example, walls so that chemicals are not scattered around. When water or the like for blowing off the chemical is blown, the chemical flows out into the respective drainage basins through the drainage pipes extending from the sulfuric acid dilution device 104a and the caustic soda dilution device 104b together with the cleaning water.
The sulfuric acid diluting device 104a and the caustic soda diluting device 104b have the same configuration of drainage pipes and drainage valves extending from the respective parts.

図２は排水升２、及びその排水升２に取り付けられる蓋部材１０を示す図であり、（ａ）は概略断面図、（ｂ）は上面図である。   FIG. 2 is a view showing the drainage basin 2 and the lid member 10 attached to the drainage basin 2, wherein (a) is a schematic cross-sectional view and (b) is a top view.

排水升２は、希釈装置１０４が設置されている個所の床部１１０に設けられた、水平断面が矩形の穴で、縁部には、床部１１０から一段下がった段部２ｂが設けられている。なお、排水升２の水平断面形状は矩形に限定されず、円形、楕円形等他の形状であってもよい。
排水升２の底部からはバルブ２ａが取り付けられた排水管２Ａが延びている。 The drainage basin 2 is a hole having a rectangular horizontal section provided in the floor 110 where the diluting device 104 is installed, and a step 2b that is one step down from the floor 110 is provided at the edge. Yes. The horizontal cross-sectional shape of the drainage basin 2 is not limited to a rectangle, and may be other shapes such as a circle and an ellipse.
A drain pipe 2 </ b> A to which a valve 2 a is attached extends from the bottom of the drainage tub 2.

排水升２には蓋部材１０が取り付けられている。
蓋部材１０は、排水升２の上部の全面を覆う板状部材１と、板状部材１の裏面に取り付けられた配管７とを備える。 A lid member 10 is attached to the drainage basin 2.
The lid member 10 includes a plate-like member 1 that covers the entire upper surface of the drainage tub 2 and a pipe 7 that is attached to the back surface of the plate-like member 1.

板状部材１は、外周部に、段部２ｂの形状に対応し、段部２ｂに載置される平坦な載置部４を有する。板状部材１の上面であって載置部４よりも内側には、窪み部５が形成されている。
窪み部５は、４つの三角形を互いの頂点が合わさるようにして組み合わせた形状で、その頂点が窪み部５の底部となっている。底部には貫通穴６が形成され、貫通穴６の下端には、配管７が連結されている。配管７には、Ｕ字トラップ７ａが設けられている。
また、窪み部５の側部の貫通穴６と異なる位置には、廃液流入用穴８が形成され、その廃液流入用穴８には、希釈装置１０４から延びる排水管３が挿入されている。なお、排水管３にはバルブ３ａが取り付けられている。 The plate-like member 1 has a flat placement portion 4 on the outer peripheral portion corresponding to the shape of the step portion 2b and placed on the step portion 2b. A recessed portion 5 is formed on the upper surface of the plate-like member 1 and inside the placement portion 4.
The hollow portion 5 has a shape in which four triangles are combined such that their vertices are aligned, and the vertex is the bottom of the hollow portion 5. A through hole 6 is formed at the bottom, and a pipe 7 is connected to the lower end of the through hole 6. The pipe 7 is provided with a U-shaped trap 7a.
Further, a waste liquid inflow hole 8 is formed at a position different from the through hole 6 on the side of the recess 5, and the drain pipe 3 extending from the diluting device 104 is inserted into the waste liquid inflow hole 8. Note that a valve 3 a is attached to the drain pipe 3.

蓋部材１０は、本実施形態では透明なアクリル板である。ただしこれに限定されず、透明であって、排水升２に流入される硫酸や苛性ソーダ等に対する耐性を有する部材であれば他の部材であっても良い。
排水升２の底部からはバルブ２ａが取り付けられた排水管２Ａが延びている。 The lid member 10 is a transparent acrylic plate in this embodiment. However, it is not limited to this, and other members may be used as long as they are transparent and have resistance to sulfuric acid, caustic soda and the like flowing into the drain 2.
A drain pipe 2 </ b> A to which a valve 2 a is attached extends from the bottom of the drainage tub 2.

希釈装置１０４において薬品のブローが行われると、薬品を含む廃液は排水管３を流れる。排水管３に取り付けられたバルブ３ａを開くと、廃液は排水升２に流入する。排水升２の底部に接続された排水管２Ａに設けられたバルブ２ａを開くと、排水升２の内部に流入した廃液は、外部へと流出される。   When the chemical blow is performed in the diluting device 104, the waste liquid containing the chemical flows through the drain pipe 3. When the valve 3 a attached to the drain pipe 3 is opened, the waste liquid flows into the drainage tub 2. When the valve 2a provided in the drain pipe 2A connected to the bottom of the drainage basin 2 is opened, the waste liquid that has flowed into the drainage basin 2 flows out to the outside.

（１）実施形態によると、蓋部材１０は透明であるので、排水升２の内部の状態の確認が容易である。 (1) According to the embodiment, since the lid member 10 is transparent, it is easy to confirm the state inside the drainage tub 2.

（２）また、蓋部材１０は排水升２の開口部の全面を覆っている。したがって、排水管３を通して薬品が流入され、排水升２の内部で内壁等での跳ね返り等が生じても、蓋部材１０の外部へ飛散することがない。また、気化した薬品が外部に拡散することもない。これに対して、例えば、蓋部材がグレーチングであった場合、薬品が蓋部材の外部に飛散、拡散する可能性がある。 (2) The lid member 10 covers the entire opening of the drainage tub 2. Therefore, even if chemicals are introduced through the drainage pipe 3 and rebound on the inner wall or the like occurs inside the drainage tub 2, it does not scatter to the outside of the lid member 10. Also, the vaporized chemicals do not diffuse outside. On the other hand, for example, when the lid member is grating, chemicals may be scattered and diffused outside the lid member.

（３）アクリル板は、硫酸に対しては比較的良好な耐性を示し、飛散等があっても、腐食等の可能性は低い。また、苛性ソーダに対しては、より良好な耐性を有しているので、腐食等の可能性はほとんどない。したがって、排水管３を通してこれらの薬品が流入され、排水升２の内部で内壁等での跳ね返り等が生じても、蓋部材１０が腐食する可能性が低い。 (3) The acrylic plate exhibits a relatively good resistance to sulfuric acid, and even if it is scattered, the possibility of corrosion or the like is low. Also, since it has better resistance to caustic soda, there is almost no possibility of corrosion or the like. Therefore, even if these chemicals are introduced through the drainage pipe 3 and the inner wall or the like rebounds inside the drainage tub 2, the possibility that the lid member 10 is corroded is low.

（４）蓋部材の中央部に窪み部５が形成され、窪み部５の底部に貫通穴６が形成されているので、希釈装置１０４から延びる排水管３からの流水以外の、床部１１０を流れる排水も排水升２に流入することが可能である。 (4) Since the hollow part 5 is formed in the center part of the lid member and the through hole 6 is formed in the bottom part of the hollow part 5, the floor part 110 other than the flowing water from the drain pipe 3 extending from the diluting device 104 is provided. The flowing drainage can also flow into the drainage basin 2.

（５）蓋部材の中央部に窪み部５の底部に形成されたに貫通穴６には、Ｕ字状の配管７が接続されている。したがって、上述のように、床部１１０を流れる排水も排水升２に流入することが可能であるが、排水升２内に流入した硫酸等より発生したガスが逆流して外部へ放出される可能性が低い。 (5) A U-shaped pipe 7 is connected to the through-hole 6 formed in the bottom of the recess 5 at the center of the lid member. Therefore, as described above, drainage flowing through the floor 110 can also flow into the drainage basin 2, but gas generated from sulfuric acid or the like flowing into the drainage basin 2 can flow backward and be released to the outside. The nature is low.
