Aramid fiber filter bag for dedusting and filtering industrial waste gas

Abstract

The invention discloses an aramid fiber filter bag for dust removal and filtration of industrial waste gas. The aramid fiber filter bag comprises a filter bag mounting port, an external filter bag, a sliding fixing hoop, a screw base, a fixing screw and an absorption assembly; the filter bag mounting port internally comprises two types of embedded sleeves, and the first type of embedded sleeve is fixedly provided with a filter sieve plate through a fixing folded plate; large-particle dust in waste gas can be intercepted by the filter screen plate and is prevented from entering the external filter bag to cause damage to a filter bag shell or an assembled filter screen bag, and the circulating speed of the waste gas is limited by a filter opening in the bottom of the embedded sleeve, so that the waste gas can smoothly enter the external filter bag to complete the filtering the dust in the waste gas. Meanwhile, the external filter bag is assembled through a bolt assembly and is convenient to disassemble, clean and install, multi-stage filtration of the filter bag on the waste gas is effectively achieved, the filter bag is rapid and convenient to assemble and disassemble, internal cleaning is convenient, and therefore blockage is avoided.

Description

technical field [0001] The invention relates to the technical field of industrial dust removal filter bags, in particular to an aramid filter bag used for dust removal and filtration of industrial waste gas. Background technique [0002] Industrial waste gas refers to the general term of various pollutant gases discharged into the air generated during fuel combustion and production processes in the factory area. These waste gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride , carbon monoxide, lead-mercury sulfate, beryllium compounds, soot and productive dust, if discharged into the atmosphere, will pollute the air. More serious harm to human health. In industry, filter bags are usually used for dust removal of industrial waste gas, and then the waste gas is treated, while filter bags are usually made of aramid fiber. The full name of aramid fiber is aramid fiber. , is a new type of high-tech synthetic f...

AI Technical Summary

Problems solved by technology

[0004] 1. When the aramid filter bag is used for exhaust gas dust removal, the large particles of impurities in the exhaust gas will impact the inside of the filter bag for a long time, which will easily cause damage to the inside of the filter bag;

[0005] 2. After a period of use of the aramid filter bag, the disassembly process is relatively cumbersome, and it is difficult to clean the dust in the filter bag, resulting in the blockage of the filter bag
