Injection system of pulse type bag-type dust collector

Abstract

The invention discloses a blowing system of a pulse type bag-type dust collector, which comprises a plurality of groups of blowing pipes fixed in a box body, each group of blowing pipes are arranged in parallel along the box body, the middle part of each blowing pipe is provided with a middle support frame located on the box body, one end of each blowing pipe is provided with an end support frame located on the box body, and a plurality of nozzles are arranged on each blowing pipe at equal intervals. The blowing pipe is connected to an electromagnetic pulse valve through a pulse valve connecting pipe, and an air distributing bag is arranged between the pulse valve connecting pipe and the electromagnetic pulse valve. The pulse type bag-type dust collector blowing system provided by the invention has the advantages of good dust removal and blowing effects, high air compression force, reasonable structure, convenience in installation, low failure rate, less blowing air consumption, uniform and rapid air flow injection, small blowing resistance, good sealing performance, capability of realizing automatic control and more obvious dust removal effect.

Description

technical field [0001] The invention belongs to the technical field of bag-type dust collectors, and in particular relates to a blowing system of a pulse-type bag-type dust collector. Background technique [0002] At present, there are many types of low-pressure long bag pulse dust collectors, and there are more styles of bag cleaning devices, among which the pulse injection system is the most widely used. [0003] At present, there are two types of pulse injection systems on the market: one is to spray the entire box, which is suitable for bag filter with short bag length; the other is to spray the bag with multiple injection pipes For spraying, it is suitable for bag filter with medium and long-distance bag length; while the existing low-pressure long-bag pulse filter has a wide variety, but in order to reduce the floor space, save costs, and deal with the air volume at the same time, the bag filter The longer the length, the better. This determines that most low-pressur...

Problems solved by technology

[0004] The blowing effect of the existing pulse injection system is not ideal, the compressed air injected is not strong enough, and the compressed air flow is scattered, resulting in insufficient blowing force to the bag, and the dust on the bag is not completely removed, which affects the subsequent bag dust removal effect. Negative impact, and most of the injection pipes are designed with a flat hole nozzle, and the high-speed air flow instantly changes direction at a right angle during pulse jet cleaning.
