Abstract:

When lifting the coke bucket by crane and charging the red-hot coke into the CDQ chamber through charging device,escaping dust is found at the joint between the coke bucket lid and the CDQ chamber,around the coke bucket,and at the joint between the charging chute and the skirt of the charging device,which is caused by actual pressure fluctuation varying with coke charging at the CDQ chamber mouth.In this paper,through the optimization of the movable dedusting duct sealing device,the improvement of the deformation resistance of the movable hood and the innovation of the chute top sealing device,the dust escaping from the charging device can be effectively controlled,and the ambient environment can be improved.
