Efficient de-dusting gas box type bag dust collector

Abstract

The invention discloses an efficient de-dusting gas box type bag dust collector and belongs to the technical field of industrial de-dusting equipment. The efficient de-dusting gas box type bag dust collector comprises a box body and an ash bucket, wherein an air inlet pipe is arranged on the ash bucket; a centrifugal sedimentation device is arranged in the ash bucket and comprises an outer drum and an inner drum which are coaxially mounted; the axes of the outer drum and the inner drum are overlapped with the axis of the box body; the upper end of the outer drum is closed while the lower end of the outer drum is open; an air outlet is formed on the upper part of the side wall of the outer drum; the air inlet pipe passes through the upper end of the outer drum and is connected with the upper end of the inner drum; through holes are uniformly distributed in the circumferential wall of the inner drum; a centrifugal fan is arranged at the bottom of the inner drum; the lower end of the inner drum is higher than the lower end of the outer drum.

Description

technical field [0001] The invention belongs to the technical field of industrial dedusting equipment, and in particular relates to an air box-type bag-type deduster for high-efficiency dedusting. Background technique [0002] The bag filter is a dry dust filter device, which is suitable for collecting fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-woven felt, and uses its filtering effect to filter the dusty gas. Filtration, when the dust-containing gas enters the bag filter, the dust with large particles and specific gravity will settle down due to the action of gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust will be blocked, making The gas is purified. The air inlet of the current air box bag filter is mostly set on the side wall of the ash hopper, and a dust filter bag is set above the ash hopper. After entering the ash hopper, the dusty gas rises to the filter bag ...

AI Technical Summary

Problems solved by technology

The air inlet of the current air box bag filter is mostly set on the side wall of the ash hopper, and a dust filter bag is set above the ash hopper. After entering the ash hopper, the dusty gas rises to the filter bag for filtration. Large, the speed of air intake is very fast, and the larger particles in the gas are difficult to settle quickly due to the action of gravity, but will rise with the air flow and directly collide with the bag, resulting in a large friction between the two, causing the bag In addition, only larger particles of dust can settle in the traditional air box bag filter, while smaller particles of dust need to be filtered through the filter bag, resulting in a larger filter load of the filter bag
