Rotary reverse-blowing flat-belt dust remover

Abstract

The invention relates to the technical field of waste gas purification equipment, and discloses a rotary reverse-blowing flat-belt dust remover which comprises a filter cylinder, an ash bucket is fixedly connected to the bottom of the filter cylinder, an ash discharging valve is fixedly mounted at the bottom of the ash bucket, and an upper cover is fixedly connected to the upper end of the filtercylinder. Through the arrangement of an electromagnet, a strip-shaped magnet and an electric connection structure, a flat cloth bag shrinks inwards under the action of gas pressure, when a large amount of dust is accumulated on the surface of the flat cloth bag, the flat cloth bag shrinks inwards more violently due to air permeability reduction, and when the flat cloth bag shrinks until the upperconducting strip and the lower conducting strip make contact with each other, the electromagnet is powered on to generate magnetism; due to the magnetism opposite to the opposite face of the strip-shaped magnet, when the flat cloth bag is flattest, the flat cloth bag can rebound suddenly under the action of the magnetic force of the electromagnet, the flat cloth bag is made to vibrate left and right in the air filtering process, falling of dust on the surface of the flat cloth bag is facilitated, the filtering efficiency of the flat-belt dust remover is improved, and the reverse blowing frequency is reduced.

Description

technical field [0001] The invention relates to the technical field of exhaust gas purification equipment, in particular to a rotary reverse blowing flat belt dust collector. Background technique [0002] The rotary reverse blowing flat bag dust collector is a kind of bag dust collector. It is a dry dust filter device, which is suitable for collecting fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-woven felt. It is made by using the filter function of fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag filter, the dust with large particles and specific gravity will settle down due to the action of gravity and fall into the ash hopper. When the dust gas passes through the filter material, the dust is blocked and the gas is purified. [0003] However, after the current flat bag filter is used for a long time, a large amount of dust will adhere to the surface of the filter bag, which will block the fil...

Problems solved by technology

[0003] However, after the current flat bag filter is used for a long time, a large amount of dust will adhere to the surface of the filter bag, which will block the filter bag, which will lead to low filtration efficiency; moreover, the flat bag filter is still in the upper chamber The anti-blowing system is equipped in the middle. During the dust removal process, every once in a while, the air filter is stopped, and the anti-blowing system is started to blow the inside of the filter bag, so that the dust attached to the surface of the bag falls outward. It can be seen that the flat bag dust collector The dust removal operation cannot be carried out continuously, the dust removal efficiency is greatly reduced, and when the air is sprayed, the cloth bag will expand under the gas pressure, and the cloth belt will be deformed when the cloth bag expands, and the textile mesh of the cloth bag will be enlarged. The mesh of the dust bag becomes larger and loses the filtering effect
