Dust-removing filtering bag with dust-removing area enlarging function

Abstract

The invention relates to the technical field of dust-removing filtering bags, in particular to a dust-removing filtering bag with a dust-removing area enlarging function. The dust-removing filtering bag comprises a dust remover shell body, wherein the bottom of the dust remover shell body is fixedly connected with a tapered barrel; an ash outlet is formed in the bottom of the tapered barrel; an air inlet pipeline is arranged on a bottom side wall of the dust remover shell body; the dust remover shell body is internally fixedly connected with a round plate; the lower side of the round plate isfixedly connected with a columnar mounting body; a plurality of mounting through holes are uniformly formed in the columnar mounting body; a dust-removing body is arranged in the middle of each mounting through hole; the top end of each dust-removing body is fixedly connected with the lower side of the round plate; a circulating hole is formed in a contact part of each dust-removing body and the round plate. The dust-removing filtering bag provided by the invention has the following beneficial effects that waste gas uniformly enters the mounting through holes and then penetrates through the dust-removing bodies; after the waste gas is filtered by the dust-removing bodies, the waste gas is discharged out through the circulating holes; the plurality of dust-removing bodies which are uniformly arranged are used for dispersing the waste gas and removing dust, so that a dust-removing area is effectively expanded and a better dust-removing effect is realized; the dust-removing filtering baghas wide popularization and application value.

Description

technical field [0001] The invention relates to the technical field of dust-removing filter bags, in particular to a dust-removing filter bag with the function of expanding the dust-removing area. Background technique [0002] Dust filter bag is a kind of high-efficiency dust filter material, which has good ventilation performance, high dust removal efficiency, and has certain acid resistance, alkali resistance and heat resistance. Multi-sided brushing is used in the weaving process, which increases the fabric thickness and is full of elasticity. , The dust removal effect is very good, and the dust removal rate can reach 99.999%. The dust filter bag is made of polyester staple fiber or long fiber, and its service life is generally 4-6 times that of glass fiber fabric. It has good air permeability, high dust collection rate, and the dust removal efficiency can reach 98.99%. [0003] However, due to the limitation of the space in the dust collector shell, the number of filter...

AI Technical Summary

Problems solved by technology

[0003] However, due to the limitation of the space in the dust collector shell, the number of filter cloths cannot be installed too much, and the area cannot be too large. As a result, the overall area of ​​conventional filter cloths is small, and it is impossible to complete the filtration of large-capacity flue gas in a short time. Low, can not meet the needs of industrial production, does not fundamentally solve the problem of filter cloth filtration speed, if forcibly increase the smoke volume of filter cloth per unit area, increase the dust removal strength of filter cloth, will accelerate the aging of filter cloth, make it The filtration speed gradually decreases, reducing its service life
