Lower opening type coke discharging ducting device

Abstract

The invention relates to a lower opening type coke discharging ducting device. The device is arranged above an exhaust hood of a coke guide car and comprises an air gathering pipeline, a valve bank and a docking device, wherein the bottom end of the air gathering pipeline is provided with a chassis bracket, the valve bank is fixedly installed on the chassis bracket, and the docking device is installed on the top end of the exhaust hood of the coke guide car and corresponds to the position of the valve bank. The device has the advantages of reasonable structural design, small volume, light weight and good smoke exhaust effect, effectively saves the dedusting cost, and increases the enterprise revenue.

Description

technical field [0001] The present invention relates to a dust removal device, in particular to a bottom-opening type coke discharge smoke and dust conduction device. Background technique [0002] In the previous coke oven dust removal design, when the coke is pushed out of the carbonization chamber, it breaks and burns in the air. The smoke and dust generated by the coke are collected by a large suction machine installed on the coke trap and moving with the coke guide car. The hood is collected, and then the flue gas is sent to the dust collection pipeline valve group set above the coke table through the side docking device of the coke guide car, and finally sent to the dust removal ground station for purification. This arrangement has the following defects: 1) A large pipe support needs to be installed above the coke table, which not only covers a large area, but also has a large initial investment; To reduce the load of the third rail, if the plan of canceling the third ...

AI Technical Summary

Problems solved by technology

This arrangement has the following disadvantages: 1) a large pipe support needs to be installed above the coke platform, which not only occupies a large area, but also requires a large initial investment; If the load of the third rail is reduced, if the plan of canceling the third rail is adopted, it is necessary to add tens of tons of counterweight to the coke stopper; 3) Due to the long horizontal pipe, the flue gas flow is not smooth, which affects the control effect of the flue gas; 4) Since the dust collection point of the burner smoke is far away from the docking port, it is necessary to set up a booster fan to introduce the burner smoke into the large suction hood, which not only increases energy consumption, but also, due to the harsh working environment of the booster fan, in actual operation, it is often necessary to Repair and replace parts of the booster fan; 5) The flap of the side-joint pipeline valve group is sealed with heat-resistant asbestos rope, which has a certain amount of air leakage. Large gap air leakage rate

The large air leakage rate leads to the increase of the main equipment capacity of the ground dust removal station, which increases the initial investment and operating costs
