High-temperature-resistant dedusting filter bag based on multiple filter subunits

Abstract

The invention discloses a high-temperature-resistant dedusting filter bag based on multiple filter subunits. The high-temperature-resistant dedusting filter bag comprises end fixing rings, butt-jointseats, a filter and a dedusting filter bag body. Four expanding rings are arranged at the lower ends of the end fixing rings, the butt-joint seats are fixedly connected to inner walls of the expandingrings and the end fixing rings, telescopic supporting rods are inserted into the butt-joint seats, the four expanding rings jointly form a circular structure, two ends of each expanding ring are provided with hidden notches, telescopic rings are slidably connected in the hidden notches, positioning blocks are fixedly connected to end inner walls of the expanding rings, fastening plates are in fastened connection with outer sides of the positioning blocks, and lower ends of the expanding rings are connected with the filter part through the telescopic supporting rods. By arrangement of the expanding rings and the telescopic supporting rods in the high-temperature-resistant dedusting filter bag, internal space adjustment of the telescopic supporting rods is realized through adjustment, applicability to various types of high-temperature-resistant dedusting filter bags is realized, and an application range is expanded.

Description

technical field [0001] The invention relates to the technical field of high-temperature-resistant dust-removing filter bags, in particular to a high-temperature-resistant dust-removing filter bag based on a plurality of sub-filter units. Background technique [0002] Bag dust removal equipment is a kind of equipment that separates dust and dust from flue gas. It is widely used in gas dust removal in steel, thermal power generation, cement, mining and other industries. With the continuous improvement of the country's environmental protection requirements, environmental protection policies are increasingly Strictly, all manufacturers attach great importance to environmental protection, and use a large number of bag dust removal equipment to deal with polluted waste gas and control post dust. There are still the following disadvantages: [0003] 1. The size of the support frame of the traditional high temperature resistant dust removal filter bag is fixed, resulting in a fixed...

AI Technical Summary

Problems solved by technology

[0003] 1. The size of the support frame of the traditional high temperature resistant dust removal filter bag is fixed, resulting in a fixed internal space of the high temperature resistant dust removal filter bag, so that the high temperature resistant dust removal filter bag needs to be customized according to the specific model to narrow the scope of application;

[0004] 2. The internal structure of the traditional high-temperature-resistant dust removal filter bag is simple, resulting in poor filtering effect on flue gas, so that there is still a lot of dust in the discharged gas, which pollutes the air;

[0005] 3. The traditional high temperature resistant dust removal filter bag lacks the vibration structure of the filter bag, which is not convenient to clean the dust on the inner wall of the filter bag
