Bag dust collector with self-dust-cleaning function

Abstract

The invention belongs to the technical field of dust removers, and particularly discloses a bag dust collector with a self-dust-cleaning function. The self-dust-cleaning function of a filter bag is achieved by adopting the filter bag with a smooth surface and an air inlet in the tangential air inlet direction in the bag dust collector. In addition, a double-layer dust filtering device is adopted, the filtering area of the dust collector is greatly increased, the problem that the filtering area is reduced as the filter bag with the smooth surface is adopted is solved, and the dust collecting effect is achieved by means of air circulation between inside and outside filter bag bodies. The bag dust collector has the advantages of being low in cost, capable of working continuously and suitable for movable dust collection equipment, and having few fault points.

Description

technical field [0001] The invention belongs to the technical field of bag-type dust collectors, and specifically discloses a bag-type dust collector with a self-cleaning function. Background technique [0002] The existing bag filter generally includes a dust removal chamber, an ash bin, a dust filter device, a dust removal driver and a dust removal device. The top of the body, the dust filter device is set in the dust chamber. An air outlet is provided on the top of the dust removal chamber, and an air inlet is provided on the side cavity of the dust removal chamber or the ash bin. The dust-laden gas enters the dust removal chamber from the air inlet under the action of the dust removal driver. After being filtered by the dust filter device, the dust is captured on the filter bag, and the clean gas is discharged into the atmosphere from the air outlet. When the dust on the dust filter device gradually increases, it will affect the dust collection effect and dust collecti...

AI Technical Summary

Problems solved by technology

[0003] In the industry, the electromagnetic pulse injection device is generally used to realize the dust removal function of the dust collector. This dust removal device has the advantages of flexible control and mature technology. Pipeline, high cost, many failure points, not suitable for mobile dust removal equipment

In addition, because the dust removal effect will be affected when the nozzle is cleaned, this kind of dust removal device is not suitable for long-term continuous work.
