A bag filter

Abstract

The invention relates to a new type of bag dust collector, which includes a shell, an ash hopper, a cover plate and a horizontal partition installed inside the shell. The partition divides the inside of the shell into two parts that are not connected up and down. The ash hopper is installed below the shell, and the cover plate is installed above the shell. A mixing chamber is formed between the shell, the ash hopper and the partition, and a collecting chamber is formed between the shell, the cover plate and the partition; There is an inner cylinder placed under the partition, and the cover plate has an air inlet tube vertically penetrating through the cover plate, and the lower end of the air inlet tube penetrates the partition board; there are multiple filter bags placed in the mixed flow chamber on the partition board, and the filter bag The upper end goes through the partition upwards and is connected with the partition. One side of the filter bag is placed inside the inner cylinder, and the other side of the filter bag is placed outside the inner cylinder; there is a diversion bucket with the opening facing downward in the mixed flow chamber, and the diversion bucket is placed It is arranged under the inner cylinder and is coaxial with the inner cylinder. The opening of the diversion bucket is connected with the ash bucket through a plurality of connecting ribs; there is an air outlet connected with the collecting chamber on the shell.

Description

technical field [0001] The invention relates to the field of doors and windows, in particular to a new type of bag filter. Background technique [0002] The bag filter is a dry dust filter device, which is suitable for capturing fine, dry, non-fibrous dust, and uses the filtering effect of the filter material to filter the dust-containing gas to purify the gas; when the filter material is used for a period of time After that, due to the effects of sieving, collision, retention, diffusion, static electricity, etc., a layer of dust accumulates on the surface of the filter bag. This layer of dust is called the primary layer. In the subsequent movement process, the primary layer becomes the main filter of the filter material. Relying on the effect of the primary layer, the filter material with larger mesh can also obtain higher filtration efficiency; therefore, with the accumulation of dust on the surface of the filter material, the efficiency and resistance of the dust collecto...

Problems solved by technology

[0004] In view of the above situation, in order to make up for the technical deficiencies of the existing technology, the present invention provides a new type of bag filter to solve the problem that the existing dust collector cannot effectively protect the first layer of dust when cleaning.
