- a backwash gas buffer tank 9 is provided upstream of these backwash gas systems 4, and each pressurized fluidized bed boiler filter and the backwash gas buffer tank 9 are connected via a pipe 10. Has been.
- Two high-pressure gas compressors 11 are provided upstream of the backwash gas buffer tank 9, and one of the two is used as a spare machine.
- the operation of the backwashing gas system 4 having such a configuration is performed as follows. That is, the high-temperature dust-containing gas that has entered from the dust-containing gas inlet 12 disposed at the top of the can 1 of the filter for the pressurized fluidized bed boiler is the upper two filter block constituted by the honeycomb element 2 of the porous body. The remaining high-temperature dust-containing gas is divided into cylinders divided by an upper partition tube plate (partition plate) 13, a lower partition tube plate (partition plate) 14, and an inner cylinder / outer cylinder partition plate arranged at the lower part. Dust is removed by two filter blocks by the mold element 3.

- the dust removed by each filter block falls to a dust hopper provided at the lower part on the high temperature dust-containing gas side and is discharged from the dust hopper outlet 16.
- the dust adhering to the high-temperature gas-containing gas side of each element does not necessarily fall from itself, and it generates a normal reverse gas flow, that is, the pressure wave of the high-pressure gas in the reverse direction is extremely short. It is necessary to increase the gas pressure by loading for a time (for example, 0.5 seconds) and to remove dust adhering to the high-temperature dust-containing gas side, that is, backwashing. This backwash is usually performed cyclically in order for each unit block, and the backwash interval is planned to be about several minutes.
- the backwash gas pre-valve 6 first moves slowly from the fully closed position to the fully open position over a predetermined time (for example, 2 to 10 seconds).

- the backwashing gas post-valve 7 moves quickly from the fully open position to the fully closed position in a very short time (for example, 0.1 to 1 second).
- the backwash gas pre-valve 6 remains in the fully open position and does not move (maintains the fully open position).
- a predetermined time for example, 1 to 2 seconds
- the backwashing gas pre-valve 6 is moved from the fully open position to the fully closed position for a predetermined time (for example, 2 to 10).
- the backwashing gas pre-valve 6 is fully closed and the backwashing cycle is completed.
- a predetermined time for example, 4 to 10 minutes
- the wear of the rotary shaft, the bearing, the valve body and the like of the backwashing gas pre-valve 6 can be reduced as compared with the conventional one. Even when the wear of the rotating shaft, bearing, valve body, etc. is significant, the flow path to which the backwashing gas pre-valve 6 and backwashing gas post-valve 7 are connected is completely established by setting the backwashing gas pre-valve 6 to the fully closed position. Therefore, it is possible to ensure the reliability of the backwashing valve composed of these backwashing gas pre-valve 6 and backwashing gas post-valve 7.
- the backwash gas pre-valve 6 is always maintained in the fully open position (except when it is necessary to be in the fully closed position). Different from the one. That is, when the backwash cycle starts, the backwash gas post-valve 7 moves quickly from the fully closed position to the fully open position in a very short time (eg, 0.1 to 1 second), and the backwash gas post-valve 7 is fully opened. At the position, backwashing is performed for a very short time (for example, 0.1 to 1 second).
- the backwashing gas post-valve 7 moves quickly from the fully open position to the fully closed position in a very short time (for example, 0.1 to 1 second), and the backwash cycle is completed.
- a predetermined time for example, 4 to 10 minutes
- the backwashing gas post-valve 7 starts to move again from the fully closed position to the fully opened position, and the next backwashing cycle is started.
- the wear of the rotary shaft, the bearing, the valve body and the like of the backwashing gas pre-valve 6 can be reduced more than that of the first embodiment. Even when the rotating shaft, the bearing, the valve body, etc. of the valve 7 are significantly worn, the backwashing gas pre-valve 6 and the backwashing gas post-valve 7 are connected by setting the backwashing gas prevalve 6 to the fully closed position. The passage can be completely shut off, and the reliability of the backwashing valve comprising the backwashing gas pre-valve 6 and the backwashing gas post-valve 7 can be ensured.
- the present invention is not limited to the above-described embodiment, and various changes and modifications can be made without departing from the gist of the present invention, such as the number of backwash valves and the operation order.
- the filter backwashing apparatus is not only applicable to the coal gasification combined power generation system including the can 1 shown in FIG. 1, and includes, for example, the can 21 shown in FIG. 4.
- the present invention can also be applied to a coal gasification combined power generation system.

Description
本発明の第1の態様に係るフィルタの逆洗装置は、缶体内に収納した複数のフィルタエレメントよりなる複数のフィルタブロックと、これらフィルタブロックを仕切りもしくは支持する仕切板とを有し、前記缶体内が粉塵ホッパを含む含塵ガス用空間と複数の清浄ガス用空間とに区画されている、多孔質体を用いた除塵装置におけるフィルタの逆洗装置であって、前記複数の清浄ガス用空間またはフィルタエレメント出口にそれぞれ接続された清浄ガス導出管の内部もしくはその上流空間内部に、前記フィルタエレメントへ向かう逆洗ノズルが設置され、前記フィルタブロック毎に周期的に同フィルタエレメントの逆洗を行うフィルタの逆洗装置において、各フィルタブロック毎に設けられた逆洗用気体の導入管に逆洗用気体を制御する第1の逆洗弁と、この第1の逆洗弁よりもゆっくりとした速度で動作する第2の逆洗弁とが2個直列に配置されている。
なお、逆洗サイクルの間、および逆洗サイクルと逆洗サイクルとの間、第1の逆洗弁は全閉位置のままで動かない(全閉位置を維持する)。
本実施形態において、フィルタブロックは、缶体1の上部のハニカム型エレメント(フィルタエレメント)2に2ブロック、下部の円筒型エレメント(フィルタエレメント)3に2ブロックの合計4ブロック設けられている。そのため、逆洗ガス系統4は4系列に分かれ、各系統には、対応するブロックに必要な数の逆洗ノズル5が設けられており、逆洗ノズル5の上流側には、逆洗ガス前弁(第2の逆洗弁)6、逆洗ガス後弁(第1の逆洗弁)7、および手動バイパス弁8よりなる逆洗弁のセットが設けられている。
逆洗ガスバッファタンク9の上流には、2台の高圧ガス圧縮機11が設けられており、2台のうちの1台は予備機として使用される。
図3に示すように、本実施形態においては、逆洗ガス前弁6が常時(全閉位置にする必要があるとき以外は)全開位置に維持されるという点で上述した第1実施形態のものと異なる。
すなわち、逆洗サイクルが開始すると、逆洗ガス後弁7が全閉位置から全開位置へと極短時間(例えば、0.1~1秒)で素速く動き、逆洗ガス後弁7が全開位置となって、極短時間(例えば、0.1~1秒)逆洗が行われる。逆洗が終了すると、逆洗ガス後弁7が全開位置から全閉位置へと極短時間(例えば、0.1~1秒)で素速く動き、逆洗サイクルが終了する。そして、所定の時間(例えば、4~10分)経過すると、逆洗ガス後弁7が再び全閉位置から全開位置へと動きだし、つぎの逆洗サイクルが開始する。
なお、図4中の符号22,23,24はそれぞれ、ガス出口管、円筒型エレメント(キャンドル型フィルタエレメント)、上部仕切板(チューブシート)を示している。
