Cloth bag deduster for waste gas treatment

Abstract

The invention discloses a cloth bag deduster for waste gas treatment. The cloth bag deduster comprises a shell, an air inlet, an air outlet, a cover plate, a dust hopper, a cindervalve, board plug valves II, cloth bags and a tubesheet. One side of the shell is equipped with the conical bucket shaped air inlet, and the big end of the air inlet is in fixed connection with the shell; the other side of the shell is equipped with the conical bucket shaped air outlet, and the big end of the air outlet is in fixed connection with the shell; the tubesheet is disposed on one side in the shell, the airinlet is located under the tubesheet, and the air outlet is located above the tubesheet; the tubesheet is equipped with a plurality of tube holes, in which the cloth bags are disposed; the dust hopperis disposed on one side under the shell; the cindervalve is disposed on one side under the shell; the cover plate is arranged at the top of the shell on one side, and is equipped with several groupsof board plug valves II in staggered arrangement. The cloth bag deduster provided by the invention utilizes the board plug valves to achieve modularization of the inside, can realizes non-stop replacement or maintenance during replacing cloth bags only by closing corresponding board plug valves, and lowers the production loss of enterprises.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, in particular to a bag filter for waste gas treatment. Background technique [0002] The bag filter is a dry dust filter device; it is suitable for collecting fine, dry, non-fibrous dust; the filter bag is made of textile filter cloth or non-woven felt, and uses the filtering effect of the fiber fabric to filter the dust The gas is filtered. When the dusty gas enters the bag filter, the dust with large particles and specific gravity will settle down due to the effect of gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust will be blocked. The existing bag filter needs to be closed when the filter bag is maintained or the bag needs to be replaced due to broken bags, and then the bag cage can be taken out, and then the filter bag can be maintained or replaced. , Downtime will inevitably affect the normal pr...
