Dedusting wind pressure balancing device

Abstract

The invention discloses a dust removal wind pressure balancing device. The device comprises a fan, one side of the fan is connected with a chimney matched with a fan opening in specification and size,the chimney is connected with a bag-type dust remover through an outlet connecting pipeline, the side, opposite to the outlet connecting pipeline, of the bag-type dust remover is connected with a fire-retardant box cooler through a connecting pipeline, and one end of the fire-retardant box cooler is connected with a dust removal main pipe of coke oven equipment through a pipeline and elbow structure. Compared with like devices in the prior art, the device of the invention has the following advantages: a residual pressure valve is specially arranged at the pipeline opening of the fan, and whenthe suction force exceeds a fixed value, the residual pressure valve is automatically opened to supplement air to adjust the pressure so as to guarantee safe operation of the pipeline; the device isintegrally closed tightly, sensitive in reaction, convenient to adjust and attractive in appearance; energy is not consumed compared with traditional smoke dust treatment equipment; and the dust removal effect is not affected by the sucked air amount.

Description

technical field [0001] The invention relates to the field of smoke and dust treatment in the coking process of a coking plant, in particular to a dust removal and balance wind pressure device. Background technique [0002] Since the 21st century, my country has built a number of coke ovens with a height of 4.3 meters or more. During the process of coal charging and coke discharge, a large amount of high-temperature bursts of smoke and dust are generated in the coal charging hole and coke discharge. The main pollutants in the flue gas are There are dust, benzene soluble matter, benzopyrene, etc., which seriously pollute the working area and the surrounding environment of the factory. The affected area is relatively large and endangers the health of workers and residents. The state attaches great importance to solving the problem of coke oven smoke pollution and thoroughly controlling coke oven smoke and dust The pollution problem has become an urgent environmental protection pr...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that due to the disadvantages of the structural design of the smoke and dust treatment equipment in the existing coking process, the main pipe in front of the dust collector of the ground dust removal station is severely corroded, and the dry pipe is sucked due to excessive suction in the early stage, which leads to dust removal. The station affects the dust removal effect and cannot work normally
