Waste gas treatment device

Abstract

The invention relates to the technical field of waste gas treatment, specifically to a waste gas treatment device. The waste gas treatment device comprises a gas inlet pipe, a vertical pipe and a gasoutlet pipe which are communicated in sequence, wherein a filter bag is fixed in the vertical pipe; an opening of the filter bag faces downwards; a plurality of water spray pipes and flow guide pipesare arranged below the filter bag; the water spray pipes are densely disposed up and down in a staggered manner; the flow guide pipes are in one-to-one correspondence to the water spray pipes; an elastic piece is fixed above the filter bag; the elastic piece is vertically disposed; a deflector rod is also arranged beside the elastic piece; the deflector rod is rotatably connected with the verticalpipe; the deflector rod is driven by a motor; a water column sprayed by each of the water spray pipes contains tiny water drops; the tiny water drops enable dust to fall off from the filter bag; thefalling dust falls onto the water column, and the dust enters water flow of the water column, so as to prevent the dust from returning into the filter bag. The waste gas treatment device disclosed bythe invention solves the problem that the filter bag is often blocked in the prior art, and improves the waste gas treatment efficiency.

Description

technical field [0001] The invention relates to the technical field of exhaust gas treatment, in particular to an exhaust gas treatment device. Background technique [0002] At present, in the production activities of the factory, the exhaust gas generated contains a lot of harmful gases and dust, especially the exhaust gas generated in the foundry. If these exhaust gases are discharged directly into the air, it will deteriorate the air quality. Therefore, the exhaust gas needs to be treated before it is discharged. During the exhaust gas treatment process, the exhaust gas needs to be dedusted first, so as to facilitate the subsequent treatment of harmful gases. [0003] At present, filter bags are mostly used in dust removal methods in waste gas treatment, because filter bags have the advantages of low cost, high efficiency, small resistance and simple maintenance. However, when the filter bag is filtering the exhaust gas, more filtered dust will gradually accumulate in t...

AI Technical Summary

Problems solved by technology

However, when the filter bag is filtering the exhaust gas, more filtered dust will gradually accumulate in the filter bag, so that the filter bag will gradually be blocked, and generally need to be shut down for cleaning, and the blockage will also affect the passing rate of the exhaust gas and the dust removal efficiency
