Oblate bag type dust collector

Abstract

The invention relates to an oblate bag type dust collector. The oblate bag type dust collector comprises an inlet air channel 1, an outlet air channel 10, an upper box 7, a middle box 2, a patterned plate 5, a blowing device 8, an ash bucket 6, a filter bag frame 4 and oblate filter bags 3 supported by the filter bag frame 4, wherein the blowing device 8 comprises an air bag 12, a pulse valve 11 and blowing pipes 3, the blowing pipes are provided with blowing holes 14, a compressed air system 9 is connected with the air bag 12, the oblate filter bags 3 and the blowing pipes 13 are in fixed row arrangement, the blowing pipes 13 are fixed on the air purifying chamber of the upper box 7, the blowing pipes 13 and the oblate filter bags are in row correspondence, and the blowing hole 14 of each blowing pipe 13 and the oblate filter bag 3 in the same row are in one-to-one correspondence. The oblate bag type dust collector has the advantages that investment cost can be lowered while the dust collecting effect is guaranteed; fine dust generated by various process suitable for a bag type dust collector can be collected effectively, the requirements of environment protection and industrial sanitation can be satisfied, and the oblate bag type dust collector is small in floor space, low in steel consumption, reliable in operation and high in collecting efficiency.

Description

technical field [0001] The invention belongs to the technical field of dust removal and environmental protection, and in particular relates to an oblate bag type dust collector. Background technique [0002] Floor area and steel consumption are two important indicators to measure the economy of bag filter. Smaller floor area is conducive to the arrangement of dust collector on narrow sites; less steel consumption can reduce the cost of dust collector. cost. [0003] In order to improve the market competitiveness of dust removal equipment, it is necessary to improve it so that the floor area and steel consumption of the existing long-bag low-pressure pulse bag filter can be greatly reduced. [0004] According to the shape of the filter bag, the bag filter can be divided into a round bag filter and a flat bag filter. Most bag filters use round filter bags. [0005] The round bag dust collector is a single inner filter bag arranged like stars, and the dust and clean ends are ...

AI Technical Summary

Problems solved by technology

[0005] The round bag dust collector is a single inner filter bag arranged like stars, and the dust and clean ends are not separated, so there is no dedicated air flow channel; the flow rate changes greatly, so the resistance is high, the filter bag is loose, and there is dust accumulation And the risk of clogging, but also increase the air volume of dust removal

[0006] The diameter of the round filter bag is usually Ф120-Ф300mm, and the bag length is 2-10m; the diameter of the filter bag is small, and more filter area can be arranged in a certain filter space, but the number of filter bags will increase, which will increase the one-time investment of equipment ; while the rotary reverse blowing flat bag dust collector adopts the flat bag form, but it does not use one-to-one cleaning, the cleaning effect is poor, and the circular arrangement does not use the air flow organization, which is easy to break the bag
