Description

本発明は、コークス詰りが生じたコークス炉の炭化室から詰りコークスを回収する方法に関する。   The present invention relates to a method of recovering clogged coke from a coking chamber of a coke oven in which coke clogging has occurred.

コークス炉の炭化室は内壁面にカーボンが付着し、炭化室の内壁面に付着したカーボン等により炭化室にコークス詰りが生じると、コークス押出機の押出ラムにより赤熱コークスを炭化室から押し出すことができなくなるため、コークス詰りが生じた炭化室から詰りコークスを取り出す必要がある。
そこで、コークス詰りが生じた炭化室から詰りコークスを取り出す方法として、矩形状に形成された底板と、この底板の左右両端部から上方に突出する左右一対の側板とを有してなる詰りコークス取出スコップを用い、この詰りコークス取出スコップを押出ラムの前面下部に水平な軸回りに回動自在に装着した後、押出ラムを前進させて詰りコークスを炭化室から取り出す方法が特許文献１に開示されている。 The carbonization chamber of the coke oven has carbon adhering to the inner wall surface, and when the coke clogging occurs in the carbonization chamber due to carbon adhering to the inner wall surface of the carbonization chamber, the coking extruder can push out the hot coke from the carbonization chamber. Therefore, it is necessary to take out clogged coke from the carbonization chamber where coke clogging has occurred.
Therefore, as a method for taking out the coke from the coking chamber in which coke clogging has occurred, a packed coke extraction comprising a bottom plate formed in a rectangular shape and a pair of left and right side plates projecting upward from the left and right ends of the bottom plate is provided. Patent Document 1 discloses a method in which a scoop is used to remove the clogging coke from the carbonization chamber by attaching the scooping coke removing scoop to the lower portion of the front surface of the extrusion ram so as to be rotatable about a horizontal axis and then moving the extrusion ram forward. ing.

By the method for recovering clogged coke according to an embodiment of the present invention, clogged coke is removed from a carbonization chamber of a coke oven. In the case of taking out and collecting, as shown in FIG. 3, the scoop mounting shaft insertion hole 21 drilled in the scoop mounting brackets 19 and 20 of the coke extruder 17 and the side plates 13 and 14 of the jammed coke extraction scoop 11 are drilled. The scoop mounting shaft 26 is inserted into the scoop mounting shaft insertion holes 15, 16, and the jammed coke extraction scoop 11 is rotatably mounted on the lower front portion of the extrusion ram 18 (scoop mounting process). A debris collection conveyor 28 and a chute 27 for receiving clogging coke discharged from the extraction scoop 11 are disposed below the extraction scoop 11. The debris collection conveyor 28 and the chute 27 are provided and supported on a stand 17 ′ of the coke extruder 17, and can move together with the coke extruder 17. In addition, the code | symbol 31 in the figure has shown the furnace bottom of the carbonization chamber of a coke oven.

次に、図４に示すように、コークス押出機１７の押出ラム１８をコークス炉の炉幅方向（炭化室の奥行き方向）に前進させ、押出ラム１８の前面下部に装着された詰りコークス取出スコップ１１により詰りコークスをコークス炉の炭化室から取り出す（詰りコークス取出工程）。
次に、図５に示すように、押出ラム１８の背後に設けられた棒状部材２２，２３の先端が押出ラム１８の前面から突出する位置まで押出ラム１８を後退させ、押出ラム１８の前面下部に装着された詰りコークス取出スコップ１１を水平な軸回りに回動させる（スコップ回動工程）。 Next, as shown in FIG. 4, the extrusion ram 18 of the coke extruder 17 is advanced in the furnace width direction of the coke oven (the depth direction of the carbonization chamber), and the packed coke extraction scoop attached to the lower front portion of the extrusion ram 18 is installed. 11 is used to remove clogged coke from the carbonization chamber of the coke oven (clogged coke removal step).
Next, as shown in FIG. 5, the extrusion ram 18 is retracted to a position where the tips of the rod-like members 22, 23 provided behind the extrusion ram 18 protrude from the front surface of the extrusion ram 18, The coke taking-out scoop 11 attached to is rotated about a horizontal axis (scoop rotating step).

このとき、詰りコークス取出スコップ１１の底板１２は詰りコークス取出スコップ１１の回動動作に伴って傾斜し、詰りコークス取出スコップ１１の底板１２がある角度まで傾斜すると、詰りコークス取出スコップ１１によりコークス炉の炭化室から取り出された詰りコークスが詰りコークス取出スコップ１１の底板１２上を滑落し、押出機に設けられたシュート２７上に落下する。   At this time, the bottom plate 12 of the packed coke taking-out scoop 11 is inclined as the packed coke taking-out scoop 11 is rotated. The coke taken out from the carbonization chamber slides down on the bottom plate 12 of the coke removal scoop 11 and falls onto a chute 27 provided in the extruder.

シュート２７はコークス炉の炭化室から赤熱コークスの押し出すときに炭化室から零れ落ちた赤熱コークスを落骸として回収する落骸回収用チェーンコンベア２８に向けて約６．５の角度で傾斜しており、従って、シュート２７上に落下した詰りコークスはシュート２７の上面を滑落して落骸回収用チェーンコンベア２８上に投下され、この落骸回収用チェーンコンベア２８によって回収される（詰りコークス回収工程）。
なお、詰りコークス取出スコップ１１によりコークス炉の炭化室から取り出された詰りコークスをシュート２７上に落下させるときには、図５に示すように、冷却水散水ノズル２９からの冷却水３０が詰りコークス取出スコップ１１の底板１２に上方から散水される。 The chute 27 is inclined at an angle of about 6.5 toward a debris collection chain conveyor 28 that collects reddish coke spilled from the coking chamber as debris when the reddish coke is pushed out from the coking chamber of the coke oven. Accordingly, the clogging coke dropped on the chute 27 slides down on the upper surface of the chute 27 and is dropped onto the debris collection chain conveyor 28 and is collected by the debris collection chain conveyor 28 (clogged coke collection step). .
In addition, when dropping the clogging coke taken out from the carbonization chamber of the coke oven by the clogging coke removal scoop 11 onto the chute 27, the cooling water 30 from the cooling water sprinkling nozzle 29 is clogged as shown in FIG. 11 is sprayed on the bottom plate 12 from above.

また、落骸回収用チェーンコンベア２８により回収された詰りコークスはコークス押出機１７の階下に吊り下げ設置されたホッパーにコンベヤを乗り継いで搬送され、定期的にコークス炉の外部へ搬出される。
上述した本発明の一実施形態によると、押出ラム１８の前面下部に装着された詰りコークス取出スコップ１１によりコークス炉の炭化室から取り出された詰りコークスは押出機に設けられたシュート２７上に落下し、このシュート２７上を滑り落ちて落骸回収用チェーンコンベア２８上に投下されることになる。したがって、押出ラム１８の前面下部に装着された詰りコークス取出スコップ１１によりコークス炉の炭化室から取り出された詰りコークスを炭化室から赤熱コークスを押し出すときに炭化室から零れ落ちた赤熱コークスを落骸として回収する落骸回収用チェーンコンベア２８によって回収することができる。 Further, the packed coke recovered by the debris recovery chain conveyor 28 is transferred to a hopper suspended below the coke extruder 17 while being transferred to the outside of the coke oven.
According to the above-described embodiment of the present invention, the stuffed coke taken out from the carbonization chamber of the coke oven by the stuffed coke removal scoop 11 attached to the lower front portion of the extrusion ram 18 falls on the chute 27 provided in the extruder. Then, it slides down on the chute 27 and is dropped onto the debris collection chain conveyor 28. Therefore, when the coking coke taken out from the coking chamber of the coke oven is pushed out from the coking chamber by the plugging coke removing scoop 11 attached to the lower front portion of the extrusion ram 18, the red hot coke that has fallen from the coking chamber is dropped. Can be recovered by the debris recovery chain conveyor 28.

また、上述した本発明の一実施形態では、詰りコークス取出スコップ１１によりコークス炉の炭化室から取り出された詰りコークスをシュート２７上に落下させるときに詰りコークス取出スコップ１１の底板１２に冷却水を上方から散水しているので、底板１２に散水された冷却水により詰りコークスが底板１２の上面をスムーズに滑落してシュート２７上に落下させることができると共に、シュート２７上に落下する詰りコークスを冷却することができる。   Moreover, in one Embodiment of this invention mentioned above, when dropping the clogging coke taken out from the carbonization chamber of the coke oven with the clogging coke extraction scoop 11 on the chute 27, cooling water is supplied to the bottom plate 12 of the clogging coke extraction scoop 11. Since water is sprayed from above, clogged coke can be smoothly slid down the upper surface of the bottom plate 12 by the cooling water sprayed on the bottom plate 12 and dropped onto the chute 27. Can be cooled.
