Self-dedusting device of coke oven coal tower loading truck

Abstract

The invention relates to a dedusting device and particularly relates to a self-dedusting device of a coke oven coal tower loading truck. The self-dedusting device comprises a seal channel and a coal discharge valve, wherein the coal discharge valve is enclosed in the seal channel, and an inlet of the coal discharge valve is connected to the tail end of a coal tower chute located at the lower part of the coal tower; the seal channel comprises a fixed section with a flange and a bellow section, the upper part of the fixed section is connected to the coal tower chute by virtue of the flange, the tail end of the bellow section stretches and is connected with a joint of a coal hopper of the coal loading truck; the fixed section is connected with a branch duct and the branch duct is connected with the dedusting system. According to the self-dedusting device of the coke oven coal tower loading truck, the connection part between the coal tower chute and an interface of a coal hopper of the coal loading truck is enclosed into a seal chamber by virtue of the seal channel; by means of the height of a vertical secondary main air duct and the temperature difference between the gas in the main air duct and the atmosphere, negative pressure is generated in the air duct, and the coal dust and airflow inside the seal chamber are pumped into a dust remover so as to be subjected dust removal and the dust-removed coal dust is recycled.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a coke oven coal tower loading self-dust removal device. Background technique [0002] When the coke oven coal tower puts coal into the coal hopper of the coal loading vehicle, the coal flow falls freely into the coal hopper due to gravity. During this process, due to the large fall of the coal flow, coal dust will be splashed, and this part of coal dust will basically escape into the atmosphere; especially the humidity-adjusted coal, its moisture is generally 6%, and the temperature is greater than 60 ° C. When the car is running, the amount of coal dust raised is larger; at the same time, when the coal flow enters the coal hopper and the original air in the coal hopper is discharged, the air forms an airflow and drives the coal dust in the coal hopper to escape into the atmosphere, causing severe Pollution and loss of coal resources; even, due to the high temperature of the humidity-ad...

During this process, due to the large fall of the coal flow, coal dust will be splashed, and this part of coal dust will basically escape into the atmosphere; especially the humidity-adjusted coal, its moisture is generally 6%, and the temperature is greater than 60 ° C. When the car is running, the amount of coal dust raised is larger; at the same time, when the coal flow enters the coal hopper and the original air in the coal hopper is discharged, the air forms an airflow and drives the coal dust in the coal hopper to escape into the atmosphere, causing severe Pollution and loss of coal resources; even, due to the high temperature of the humidity-adjusted coal, coal dust splashes on the operator, causing burns and other safety accidents
