Description

本発明は、電気集塵器に接続され、この装置の内部を洗浄するための水を供給する水洗配管構造及びこの水洗配管の防食方法に関する。   The present invention relates to a flush pipe structure that is connected to an electrostatic precipitator and supplies water for washing the inside of the apparatus, and a corrosion prevention method for the flush pipe.

火力発電所において、ボイラより排出された排ガスは、排煙脱硝装置、電気集塵器、及び排煙脱硫装置により、夫々脱硝、集塵、脱硫が行われた後、煙突から排出される。このうち、電気集塵器には、装置内部を洗浄するための水を供給する水洗配管が接続されている。この水洗配管は、その先端が装置内部まで到達しており、装置内部の部分に水洗ノズルが取り付けられている。そして、この水洗ノズルから散水することで装置内部の洗浄を行うことができる。   In a thermal power plant, exhaust gas discharged from a boiler is denitrated, collected, and desulfurized by a flue gas denitration device, an electric dust collector, and a flue gas desulfurization device, respectively, and then discharged from a chimney. Among these, the electric precipitator is connected to a water washing pipe for supplying water for cleaning the inside of the apparatus. This flush pipe has its tip reaching the inside of the apparatus, and a flush nozzle is attached to the inside of the apparatus. And the inside of an apparatus can be wash | cleaned by sprinkling water from this washing nozzle.

上述のように、水洗配管の水洗ノズルは電気集塵器内に配置されているため、通常運転時にはこの水洗ノズルから水洗配管内に排ガスが流れ込んでしまう。また、電気集塵器は排煙脱硫装置の前に設けられているため、水洗配管内に流入する排ガスにはＳＯ３などのＳＯＸが含まれており、このＳＯ３が配管内の水に溶けたり、外部の冷気により冷却されて液化したりすることで水洗配管内に硫酸が生成される。この硫酸が原因で、電気集塵器に接続される水洗配管が腐食されてしまうという問題があった。 As described above, since the flush nozzle of the flush pipe is disposed in the electric dust collector, exhaust gas flows from the flush nozzle into the flush pipe during normal operation. Further, since the electrostatic precipitator is provided in front of the flue gas desulfurization apparatus, the exhaust gas flowing into the washing pipe includes a SO X such as SO 3, in water of the SO 3 is in the pipe Sulfuric acid is generated in the flush pipe by melting or being liquefied by being cooled by external cold air. Due to this sulfuric acid, there has been a problem that the water washing pipe connected to the electrostatic precipitator is corroded.

本発明は、上記の問題に鑑みなされたものであり、その目的は電気集塵器に内部を清掃するための水を供給する水洗配管の腐食を防止できるようにすることである。   This invention is made | formed in view of said problem, The objective is to make it possible to prevent the corrosion of the water washing piping which supplies the water for cleaning an inside to an electrostatic precipitator.

本発明の集塵器へ洗浄水を供給する水洗配管構造は、排気ガスの通路に設けられた集塵器の内部に洗浄水を供給するための水洗配管の構造であって、前記水洗配管に前記集塵器へ向かって下向きに傾斜する傾斜部を設け、前記水洗配管をこの傾斜部の下流側にて前記集塵器に接続したことを特徴とする。
上記の集塵器へ洗浄水を供給する水洗配管構造において、前記水洗配管の前記傾斜部の上流側に前記水洗配管を開閉可能な機構を設けてもよい。 The flush piping structure for supplying cleaning water to the dust collector of the present invention is a flush piping structure for supplying cleaning water to the inside of the dust collector provided in the exhaust gas passage. An inclined portion inclined downward toward the dust collector is provided, and the flush pipe is connected to the dust collector on the downstream side of the inclined portion.
In the flush pipe structure for supplying washing water to the dust collector, a mechanism capable of opening and closing the flush pipe may be provided upstream of the inclined portion of the flush pipe.

また、本発明の集塵器へ洗浄水を供給する水洗配管の防食方法は、排気ガスの通路に設けられた集塵器の内部に洗浄水を供給するための水洗配管の防食方法であって、前記水洗配管に前記集塵器へ向かって下向きに傾斜する傾斜部を設けるとともに、前記傾斜部の上流側に前記水洗配管を開閉可能な機構を設け、前記水洗配管をこの傾斜部の下流側にて前記集塵器に接続し、前記集塵器の内部に洗浄水を供給する時以外は、前記機構により前記水洗配管を閉鎖することを特徴とする。   Further, the anticorrosion method of the flush pipe for supplying cleaning water to the dust collector of the present invention is an anticorrosion method of the flush pipe for supplying cleaning water to the inside of the dust collector provided in the exhaust gas passage. The flush pipe is provided with an inclined portion that is inclined downward toward the dust collector, and a mechanism capable of opening and closing the flush pipe is provided on the upstream side of the inclined portion, and the flush pipe is disposed on the downstream side of the inclined portion. The cleaning pipe is closed by the mechanism except when it is connected to the dust collector and the cleaning water is supplied into the dust collector.

本発明によれば、電気集塵器から水洗配管内に排ガスが流入し、水洗配管内に腐食性の液体が発生しても、発生した腐食性の液体は傾斜部により電気集塵器内に流れ込むため、水洗配管が腐食するのを防止できる。   According to the present invention, even if exhaust gas flows into the flush pipe from the electrostatic precipitator and a corrosive liquid is generated in the flush pipe, the generated corrosive liquid is put into the electrostatic precipitator by the inclined portion. Since it flows in, it is possible to prevent the washing pipe from corroding.

図１は、火力発電所における排ガスの処理の流れを示す図である。同図に示すように、火力発電所では、ボイラ１０において燃料を燃焼させた際に発生した排ガスを、排煙脱硝装置２０、電気集塵器３０、排煙脱硫装置４０を通過させた後、煙突から外部に排出している。電気集塵器３０には内部を洗浄するために、外部から水を供給する水洗配管３１が接続されている。   FIG. 1 is a diagram showing a flow of exhaust gas treatment in a thermal power plant. As shown in the figure, in the thermal power plant, after passing the exhaust gas generated when the fuel is burned in the boiler 10 through the flue gas denitration device 20, the electrostatic precipitator 30, and the flue gas desulfurization device 40, It is discharged from the chimney. The electric dust collector 30 is connected with a water washing pipe 31 for supplying water from the outside in order to clean the inside.

図２は、従来の水洗配管の電気集塵器に接続された端部の近傍を示す図であり、（Ａ）は、平面図、（Ｂ）は立面図である。同図に示すように、水洗配管３１は、その先端が電気集塵器３０の内部まで到達し、電気集塵器３０内に露出している。この水洗配管３１の電気集塵器３０内に露出する部分には、水洗ノズル３５が取り付けられており、この水洗ノズル３５から散水することで、電気集塵器３０の内部を洗浄することができる。   FIG. 2 is a view showing the vicinity of an end portion connected to an electric dust collector of a conventional flush pipe, (A) is a plan view, and (B) is an elevation view. As shown in the figure, the flush pipe 31 reaches the inside of the electrostatic precipitator 30 and is exposed in the electrostatic precipitator 30. A water washing nozzle 35 is attached to a portion of the water washing pipe 31 exposed in the electric dust collector 30, and the inside of the electric dust collector 30 can be washed by spraying water from the water washing nozzle 35. .

電気集塵器３０の通常運転時には、電気集塵器３０内を排ガスが通過する。この際、水洗ノズル３５から水洗配管３１内に電気集塵器３０内を通過する排ガスが流入してしまう。ここで、水洗配管３１に流入する排ガスは、排煙脱硫装置４０を通過する前の状態であるため、ＳＯ３などのＳＯｘが含まれる。このように水洗配管３１に流入した排ガスは、水洗配管３１の装置外部にあたる部分まで流れ出る。そして、外部の冷気により排ガスに含まれるＳＯ３が冷却されることにより液化したり、水洗配管３１の装置外部の部分まで逆流した排ガスに含まれるＳＯ３が水洗配管３１内に残存する水分に溶けたりすることで、水洗配管３１内に硫酸が生成される。 During normal operation of the electric dust collector 30, exhaust gas passes through the electric dust collector 30. At this time, exhaust gas passing through the electrostatic precipitator 30 flows into the flush pipe 31 from the flush nozzle 35. Here, since the exhaust gas flowing into the flush pipe 31 is in a state before passing through the flue gas desulfurization device 40, SO x such as SO 3 is included. In this way, the exhaust gas flowing into the flush pipe 31 flows out to the portion of the flush pipe 31 that corresponds to the outside of the apparatus. Then, SO 3 contained in the exhaust gas is liquefied by being cooled by the external cold air, or SO 3 contained in the exhaust gas that has flowed back to the portion outside the apparatus of the flush pipe 31 is dissolved in moisture remaining in the flush pipe 31. As a result, sulfuric acid is generated in the flush pipe 31.

従来は、図２に示すように電気集塵器３０に接続される水洗配管３１として、配管２３６を水平に設けていたため、生成された硫酸が水洗配管３１内に長期に亘って停留してしまい、水洗配管３１の腐食の原因になるという問題があった。   Conventionally, as shown in FIG. 2, as the flush pipe 31 connected to the electrostatic precipitator 30, the pipe 236 is provided horizontally, so that the generated sulfuric acid stays in the flush pipe 31 for a long period of time. There was a problem of causing corrosion of the flush pipe 31.

これに対して、本実施形態の電気集塵器３０の配管構造は、電気集塵器３０の内部を洗浄するための水を供給する水洗配管３１が硫酸により腐食することを防止するものである。
図３は、本実施形態における水洗配管３１の電気集塵器３０との接続部近傍を示す図であり、（Ａ）は平面図、（Ｂ）は側面図である。同図に示すように、本実施形態の配管構造では、水洗配管３１として、電気集塵器３０に近づくほど上方に向かう第１の傾斜部３６Ａと、その下流側に電気集塵器３０に近づくほど下方に向かう第２の傾斜部３６Ｂとが形成され、この第２の傾斜部３６Ｂの下流側で電気集塵器３０に接続される配管３６を用いている。また、この配管３６の第１の傾斜部３６Ａと第２の傾斜部３６Ｂとの間には配管同士の接続部３７が設けられており、この接続部３７においてメガネフランジ３３を間に挟んだ状態で配管同士を接続している。 On the other hand, the piping structure of the electrostatic precipitator 30 of the present embodiment prevents the flushing pipe 31 that supplies water for cleaning the inside of the electrostatic precipitator 30 from being corroded by sulfuric acid. .
FIG. 3 is a view showing the vicinity of the connection portion of the flush pipe 31 with the electric dust collector 30 in the present embodiment, (A) is a plan view, and (B) is a side view. As shown in the figure, in the piping structure of the present embodiment, as the flush pipe 31, the first inclined portion 36A heading upward as it approaches the electrostatic precipitator 30, and the electrostatic precipitator 30 approaches the downstream side thereof. A second inclined portion 36B that is directed downward is formed, and a pipe 36 that is connected to the electrostatic precipitator 30 on the downstream side of the second inclined portion 36B is used. Further, a connecting portion 37 between the pipes is provided between the first inclined portion 36A and the second inclined portion 36B of the pipe 36, and the glasses flange 33 is sandwiched between the connecting portions 37. The pipes are connected with each other.

図４はメガネフランジ３３を示す図である。同図に示すように、メガネフランジ３３は、丸型の配管フランジ３３Ａと、閉止フランジ３３Ｂとがメガネ状に一体となった板状部材であり、配管の間に丸型の配管フランジ３３Ａを介在させることにより配管を開放することができ、また、配管の間に閉止フランジ３３Ｂを介在させることにより配管を閉鎖することができる。電気集塵器３０の洗浄作業中以外には、メガネフランジ３３により配管を閉鎖した状態とする。また、第１の傾斜部３６Ａの上流にはバルブ３４が取り付けられており、メガネフランジ３３を開放した状態でバルブ３４を開放することで水洗配管３１内に水が供給される。   FIG. 4 is a view showing the eyeglass flange 33. As shown in the figure, the spectacle flange 33 is a plate-like member in which a round pipe flange 33A and a closing flange 33B are integrated in a spectacle shape, and the round pipe flange 33A is interposed between the pipes. Thus, the pipe can be opened, and the pipe can be closed by interposing the closing flange 33B between the pipes. The pipe is closed by the glasses flange 33 except during the cleaning operation of the electric dust collector 30. A valve 34 is attached upstream of the first inclined portion 36 </ b> A, and water is supplied into the flush pipe 31 by opening the valve 34 with the glasses flange 33 open.

上述のように、電気集塵器３０の通常運転時には、ＳＯ３を含む排ガスが水洗ノズル３５から水洗配管３１内に排ガスが流入することに起因して、水洗配管３１内に硫酸が発生する。 As described above, during normal operation of the electrostatic precipitator 30, sulfuric acid is generated in the flush pipe 31 due to the exhaust gas containing SO 3 flowing into the flush pipe 31 from the flush nozzle 35.

しかしながら、本実施形態によれば、水洗配管３１内に発生した硫酸は、第２の傾斜部３６Ｂにより装置内部へと流れ込む。さらに、メガネフランジ３３により水洗配管３１が閉鎖されているため、この接続部３７よりも上流側に排ガスや硫酸が逆流することがない。このため、水洗配管３１内に硫酸が発生しても、発生した硫酸は配管内に停留せずに装置内部へと流れ込むため、水洗配管３１が腐食することを防止できる。   However, according to the present embodiment, sulfuric acid generated in the flush pipe 31 flows into the apparatus by the second inclined portion 36B. Further, since the flush pipe 31 is closed by the spectacle flange 33, the exhaust gas and sulfuric acid do not flow backward upstream of the connecting portion 37. For this reason, even if sulfuric acid is generated in the flush pipe 31, the generated sulfuric acid flows into the apparatus without stopping in the pipe, so that the flush pipe 31 can be prevented from being corroded.

なお、装置内部へと流れ込んだ硫酸の大部分は、装置内部を流れる高温の排ガスの熱気により再度気化し、水洗ノズル３５から装置内部へと流れ出す。また、気化せず水洗配管３１内に残存した硫酸は水洗ノズル３５より内部に滴下するが、装置内部には塵芥などが蓄積されているため、滴下した硫酸が装置内面に接触することは無く、装置の内部に腐食が生じることはない。   Note that most of the sulfuric acid flowing into the apparatus is vaporized again by the hot air of the high-temperature exhaust gas flowing inside the apparatus, and flows out from the washing nozzle 35 into the apparatus. In addition, sulfuric acid that does not vaporize and remains in the water washing pipe 31 is dropped inside the water washing nozzle 35, but since dust or the like is accumulated inside the device, the dropped sulfuric acid does not contact the inner surface of the device, There is no corrosion inside the device.

以上説明したように、本実施形態によれば、水洗配管３１の電気集塵器３０の接続部に、装置に向かうにつれて下降するような第２の傾斜部３６Ｂが設けられているため、水洗配管３１内に発生した硫酸がこの第２の傾斜部３６Ｂにより電気集塵器３０の内部へと流し戻されるため、水洗配管３１の腐食を防止できる。   As described above, according to the present embodiment, since the second inclined portion 36B that descends toward the apparatus is provided at the connection portion of the electrostatic precipitator 30 of the flush pipe 31, the flush pipe Since the sulfuric acid generated in 31 is caused to flow back into the electric dust collector 30 by the second inclined portion 36B, corrosion of the water washing pipe 31 can be prevented.

さらに、第２の傾斜部３６Ｂの上流側の配管の接続部３７にメガネフランジ３３を介在させ、装置の洗浄作業時以外は接続部３７において水洗配管３１を閉鎖することにより、排ガスが接続部３７より上流側へと流れ出るのを防止できる。   Further, the spectacle flange 33 is interposed in the pipe connecting portion 37 upstream of the second inclined portion 36B, and the flush pipe 31 is closed at the connecting portion 37 except during the cleaning operation of the apparatus, so that the exhaust gas is connected to the connecting portion 37. It can be prevented from flowing out further upstream.

なお、本実施形態では、接合部３７の上流側に第１の傾斜部３６Ａを設ける構成としたが、これに限らず、第１の傾斜部３６Ａが形成されておらず、第２の傾斜部３６Ｂよりも上流側の部分が水平に形成された配管を用いてもよい。   In the present embodiment, the first inclined portion 36A is provided on the upstream side of the joint portion 37. However, the present invention is not limited to this, and the first inclined portion 36A is not formed. You may use the piping in which the part upstream from 36B was formed horizontally.

また、本実施形態では、水洗配管３１として、装置への接続部の近傍に装置に向かって下降するような第２の傾斜部３６Ｂを備えた配管３６を用いることとしたが、これに限らず、図５に示すように、装置への接続部から上流に向かって垂直方向に延びる垂直部１３６Ｂを備えた配管１３６を用いる構成としてもよい。かかる構成の場合には、メガネフランジ３３を垂直部１３６Ｂの直上又は途中に設けるとよい。これにより、垂直部１３６Ｂの上流側に硫酸が溜まることを防止できる。
なお、これは、図３に示す実施形態における第２の傾斜部３６Ｂの角度を９０度とした状態にあたる。 Moreover, in this embodiment, although the pipe 36 provided with the 2nd inclination part 36B which descend | falls toward an apparatus in the vicinity of the connection part to an apparatus was used as the flush pipe 31, it does not restrict to this. As shown in FIG. 5, a pipe 136 having a vertical portion 136 </ b> B extending in the vertical direction toward the upstream side from the connection portion to the apparatus may be used. In the case of such a configuration, the spectacle flange 33 may be provided directly above or in the middle of the vertical portion 136B. Thereby, it can prevent that a sulfuric acid accumulates in the upstream of the perpendicular | vertical part 136B.
This corresponds to a state where the angle of the second inclined portion 36B in the embodiment shown in FIG. 3 is 90 degrees.

また、本実施形態では、メガネフランジ３３により水洗配管３１の開閉を切り替えることとしたが、これに限らず、開閉弁などを設ける構成としてもよい。   In the present embodiment, the opening and closing of the flush pipe 31 is switched by the glasses flange 33. However, the present invention is not limited to this, and an opening / closing valve or the like may be provided.
