In operation, when a coking chamber N of the coke oven needs to be loaded with coal cakes, the smoke guide car 300 can be moved above the coking chamber N, the central line of a straight pipe of the smoke guide pipe 300 can be aligned with the central line of the coking chamber N, and meanwhile, the central lines of the other 3 straight pipes of the smoke guide pipe 300 can also be respectively aligned with the central lines of the smoke guide holes of the other adjacent three holes.

Further, in one embodiment, referring to FIG. 5, assuming that all of the coking chambers are individually labeled with positive integers as 1, 2 … … (N-3), (N-2), (N-1), N, (N +1), (N +2), (N +3) … …, when charging the normal intermediate ovens of the stoking coke oven coking chambers with coal, three vertical pipes in the first vertical pipe member 111 of the first four-pipe type smoke guiding device 110 can be simultaneously communicated with the machine side smoke guiding holes 210 of the N carbonization chamber, (N +2) carbonization chamber, (N-1) carbonization chamber, and three standpipes in the second set of four standpipes 121 of the second four-pipe smoke guide device 120 can be simultaneously and respectively communicated with the middle row of smoke guide holes 220 of the N carbonization chamber, (N +2) carbonization chamber, (N-1) carbonization chamber, wherein, the introduced (N +2) carbonization chamber and the introduced (N-1) carbonization chamber can be in the final stage of coking.

More specifically, referring to fig. 5, when the intermediate furnace is used as the coal-charging smoke guide furnace N, the smoke guide hole corresponding to the coal-charging smoke guide furnace N may also be referred to as nth hole, and the second vertical pipe in the first vertical pipe member 111 may be aligned with the nth hole in the machine side smoke guide hole 210, and at the same time, the remaining first, third, and four vertical pipes in the first vertical pipe member 111 may also be aligned with the (N-1), (N +1), and (N +2) th holes in the machine side smoke guide hole 210, respectively; meanwhile, the second vertical tube in the second set of four vertical tubes 121 may also be aligned with the nth hole in the middle row of smoke guide holes 220, and meanwhile, the remaining first, third, and four vertical tubes in the second set of four vertical tubes 121 may also be aligned with the (N-1), (N +2) th holes in the middle row of smoke guide holes 220, respectively. The riser 320 can then lower each riser to snap into the water-sealed tank. Then, the cap-lifting mechanism 350 in each vertical tube communicating with the (N-1), N, or (N +2) th holes can be operated to lift the corresponding smoke guide cap 220, so that the three-hole carbonization chambers of the introduction hole (N-1), the coal charging hole N, and the introduction hole (N +2) are simultaneously communicated, thereby realizing the smoke removal by channel of four channels, such as the channel 1, the channel 2, the channel 3, and the channel 4 shown in fig. 5. As the (N-1) th hole carbonization chamber is at the coking end stage and the (N +2) th hole carbonization chamber is at the coking end stage, the smoke dredging guiding in at the coking middle and end stage can be realized to obtain the best smoke guiding effect, and the method is very reasonable.

Further, in an embodiment, referring to fig. 4, when the first furnace of the tamping coke oven coking chamber is charged with coal, three vertical pipes in the first vertical pipe member 111 of the first four-pipe type smoke guiding device 110 may simultaneously communicate with the machine side smoke guiding holes 210 of the N carbonization chamber, (N +1) carbonization chamber, (N +2) carbonization chamber, respectively, and three vertical pipes in the second set of four vertical pipes of the second four-pipe type smoke guiding device 120 may simultaneously communicate with the middle row smoke guiding holes 220 of the N carbonization chamber, (N +1) carbonization chamber, (N +2) carbonization chamber, respectively, wherein the introduced (N +2) carbonization chamber may be in the coking final stage and the (N +1) carbonization chamber may be in the coking middle stage.

More specifically, referring to fig. 4, when the first furnace is used as the coal-charging smoke guide furnace N, the smoke guide hole corresponding to the coal-charging smoke guide furnace N may also be referred to as nth hole, and the first vertical pipe in the first vertical pipe member 111 may be aligned with the nth hole in the machine side smoke guide hole 210, and at the same time, the remaining second, third, and four vertical pipes in the first vertical pipe member 111 may also be aligned with the (N +1), (N +2), and (N +3) th holes in the machine side smoke guide hole 210, respectively; meanwhile, a first vertical tube in the second set of four vertical tubes 121 may also be aligned with an nth hole in the middle row of smoke guide holes 220, and meanwhile, the remaining second, third, and four vertical tubes of the second set of four vertical tubes 121 may also be aligned with (N +1), (N +2), and (N +3) th holes in the middle row of smoke guide holes 220, respectively. The riser 320 can then lower each riser to snap into the water-sealed tank. Then, the cap-lifting mechanism 350 in each vertical tube communicating with the nth, (N +1) and (N +2) th holes may be operated to lift the corresponding smoke guide cap 220, so that the three carbonization chambers of the coal charging hole N, the introduction hole (N +1) and the introduction hole (N +2) are simultaneously communicated, thereby realizing the smoke removal by channel of four channels, such as the channel 1, the channel 2, the channel 3 and the channel 4 shown in fig. 4. As the (N +1) th hole carbonization chamber is in the middle stage of coking and the (N +2) th hole carbonization chamber is in the last stage of coking, the smoke dredging guiding in the last stage of coking can be realized to obtain the best smoke guiding effect, and the method is very reasonable.

Further, in an embodiment, referring to fig. 6, when the last or second last oven of the coking chamber of the tamping coke oven is charged with coal, three vertical pipes in the first vertical pipe member 111 of the first four-pipe smoke guide 110 may be simultaneously communicated with the machine side smoke guide holes 210 of the N-coking chamber, (N-1) coking chamber, (N-3) coking chamber, respectively, and three vertical pipes in the second set of four vertical pipes of the second four-pipe smoke guide 120 may be simultaneously communicated with the middle row smoke guide holes 220 of the N-coking chamber, (N-1) coking chamber, (N-3) coking chamber, respectively, wherein the introduced (N-1) coking chamber and (N-3) coking chamber may be at the last coking stage.
