ABSTRACT:
An apparatus for arresting the generation of dust from a coke dry quenching station comprising a dust collecting hood mounted on a traveling crane for transferring to the coke dry quenching station a coke bucket loaded with coke discharged from a coke oven so that the upper surface and the outer side wall of the bucket are enclosed by the dust collecting hood when the bucket is suspended from the crane, a fixed hood permanently arranged above the coke charging hole in the top of the quenching station in such a manner that the upper edge portion of the fixed hood is located adjacent to the lower edge portion of the dust collecting hood to form a practically continued hood, a suction duct attached to the fixed hood at its one end and connected to a dust collector at its other end, a movable chute disposed below the fixed hood so that it alternately changes positions with a lid which closes the coke charging hole of the quenching station, and a flange portion formed on the lower edge portion of the chute and adapted so that when the bucket is lowered the peripheral edge portion of the flange portion is received in the annular groove which is formed in the quenching station top around the coke charging hole and which is filled with water, the movable chute being adapted so that the movable chute is lowered by the weight of the bucket by an amount equal to the amount of the engagement of the peripheral edge portion in the annular groove, whereby the generation of dust during the coke charging operation is arrested.
