Description

TECHNICAL FIELD

[0001] The utility model relates to coke oven dust removal equipment technical field, especially a coke oven coke discharging dust removal device. BACKGROUND

[0002] When coke is pushed to the coke receiving device (such as coke pot or coke quenching carriage) after maturing in the coke oven, obvious smoke and dust will be generated due to high temperature, flammability and collision, which affects the production environment. Therefore, dust removal treatment needs to be carried out during the coke discharging process. The commonly used method at present is to install a dust removal cover on the coke blocking carriage at the coke side of the coke oven, guide the generated smoke and dust to the dust removal dry pipe outside the coke side of the coke oven, and then send it to the ground dust removal station for treatment. However, this scheme has the problems that the dust removal dry pipe is far away from the coke oven, has large span, needs additional support column, occupies large area, and the airflow passes through a long distance, which has large resistance, resulting in high power of the dust removal system fan. SUMMARY

[0006] Optionally, a branch pipe interface device is arranged between the branch pipe and the dust removal dry pipe, and the branch pipe interface device is used for controlling the on-off of the branch pipe and the dust removal dry pipe.

[0007] Optionally, a dust removal pipe support is arranged below the branch pipe, and the dust removal pipe support is used for supporting the branch pipe and the branch pipe interface device.

[0008] Optionally, the dust removal dry pipe is arranged directly above the column.

[0009] Optionally, a dust removal dry pipe support is arranged between the dust removal dry pipe and the column.
