Improved cloth bag dust remover

Abstract

The invention discloses an improved cloth bag dust remover. The improved cloth bag dust remover comprises a casing as well as a gas inlet end and a gas outlet end which are connected with the casing;an ash bucket is arranged at the lower end of the casing; the internal part of the casing is fixedly connected with a partition plate which is arranged horizontally; the partition plate partitions theinternal part of the casing into a gas outlet chamber and a gas filtering chamber which are arranged up and down; the gas inlet end and the gas outlet end are communicated with the gas filtering chamber and the gas outlet chamber correspondingly; the upper end of the partition plate is fixedly connected with a pressure storage mechanism; a plurality of vent holes are formed in the upper end faceof the partition plate in the circumferential direction equidistantly in a run-through way; and the lower end face of the partition plate is fixedly connected with a plurality of fixed frames corresponding to the positions of the vent holes in the circumferential direction equidistantly. When much dust is accumulated on the surface of the filter bag, the gas filtering resistance is increased and the gas filtering efficiency is reduced, dust on the surface of a filter bag can be loosened and blown down through the pressure storage mechanism, a constant-pressure gas spraying mechanism and a toggling mechanism, so that self-cleaning operation on the dust accumulated on the surface of the filter bag is completed, and energy conservation and environmental friendliness are realized.

Description

technical field [0001] The invention relates to the technical field of bag filter, in particular to an improved bag filter. Background technique [0002] The bag filter is suitable for collecting fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-woven felt. The filter function of the fiber fabric is used to filter the dusty gas. After the bag filter, big particles will settle down due to the effect of gravity and fall into the hopper. When the gas containing fine dust passing through the filter material, the dust will be blocked and the gas will be purified. [0003] With the increase of the surface area of ​​the filter bag, the air filtration resistance of the filter bag increases and the efficiency of the filter air decreases. The existing one generally uses an external high-pressure air injection pipe to blow off the ash accumulation inside the filter bag, which is not convenient enough, and it is not energy-saving and environmentally frie...

[0003] With the increase of the surface area of ​​the filter bag, the air filtration resistance of the filter bag increases and the efficiency of the filter air decreases. The existing one generally uses an external high-pressure air injection pipe to blow off the ash accumulation inside the filter bag, which is not convenient enough, and it is not energy-saving and environmentally friendly.
