Pulse bag dust collector

Abstract

A pulse bag dust collector, including a shell, a dust hopper communicated with the shell is fixedly connected under the shell, an air inlet pipe passes through the outer wall of the dust hopper, and one end extends into the dust hopper. A number of air inlet holes are evenly distributed on the end surface of the tube facing the housing, and a partition is also provided in the housing, which divides the housing into two independent cavities, and the upper cavity is connected with a The exhaust pipes are connected, and a plurality of through holes are evenly distributed on the partition, a filter bag is installed on each through hole, and a blowing pipe with the blowing direction facing the filter bag is arranged above each through hole. A plurality of turbulence devices are installed in the ash hopper between the air inlet pipe and the partition. The invention can evenly divide the dusty gas, reduce the number of pulse injections and prolong the service life of the filter bag.

Description

technical field [0001] The invention relates to a pulse bag dust collector. Background technique [0002] The DMC pulse bag filter filters the dusty gas through the filter bag, and the clean gas is discharged from the exhaust pipe. The dust-containing gas enters the ash hopper through the air inlet pipe, and the negative pressure is formed due to the operation of the fan. Due to the negative pressure, the dust-containing gas is filtered by the filter bag during the rising process, and the clean gas is exhausted into the atmosphere by the fan through the exhaust pipe. . As the filtration process continues, the dust attached to the surface of the filter bag gradually increases, and the resistance of the airflow gradually increases. When the resistance reaches the set value, the constant pressure dust cleaning program controller will give a signal (it can also be controlled regularly or manually according to needs), and the pulse valve will be opened to release the compressed...

AI Technical Summary

Problems solved by technology

When the resistance reaches the set value, the constant pressure dust cleaning program controller will give a signal (it can also be controlled regularly or manually according to needs), and the pulse valve will be opened to release the compressed air, and the injection pipe will perform pulse jet cleaning on the filter bag, so that Each filter bag expands and shrinks rapidly, thereby vibrating off the dust attached to the surface of the filter bag, so that the pressure difference between the inside and outside of the filter bag returns to the initial state, and the dust sinks into the ash hopper. In order to prevent excessive accumulation of dust, generally increase the compressed air spray Blowing times, but in the process of operation, frequent blowing of the filter bag will increase the wear and damage probability of the filter bag, and will reduce the service life of the filter bag under the condition of a certain amount of dust, and the air intake is uneven, and the load of individual filter bags larger
