Description

Technical Field

[0001] The utility model relates to the field of dust removal devices, in particular to a pulse-type bag dust removal device. Background Art

[0002] The pulse bag dust collector is a dry, high-efficiency dust collector that uses the filtering effect of porous filter bags for dust removal. When the amount of dust attached to the filter bags is large, the dust attached to the filter bags is removed by spraying compressed air into the filter bags. A nozzle connected to compressed air is installed above each bag. The input end of the nozzle is connected to the solenoid valve, pulse valve and compressed air bag in sequence. All nozzles backflush the bags to clean the dust in the bags. However, the large number of nozzles increases the cost of the equipment on the one hand, and on the other hand, in order to ensure normal filtration and discharge of gas after filtration by the filter bags, the nozzle is set above the bag opening of the filter bag. The nozzle does not contact the bag opening of the filter bag, thus resulting in some wind loss.

[0003] Therefore, in order to solve the deficiencies in the prior art, a pulse bag dust removal device with a simple structure needs to be designed. Utility Model Content

[0010] Compared with the existing technology, the pulse bag dust removal device of the utility model has the following beneficial effects:

[0011] Dust gas enters the box from the air inlet, and dust particles with heavier specific gravity fall from the discharge port to achieve preliminary dust separation; filter bags are set in the channel of the upper plate to further filter the dust in the gas, and the filtered air is discharged from the exhaust port; when the filter bags need to be cleaned, the compressed air in the compressed air bag is ejected from the pulse valve, through the pipe and the nozzle of the air outlet hood to the filter bag, and the filter bag expands and vibrates instantaneously to make the dust on the surface fall off. After cleaning the left row of filter bags, the linear guide drives the slide rod to move right to the upper side of the filter bags in the next row, so that the nozzle of the air outlet hood fits and covers the surface of the filter bags, reducing wind loss. Cleaning one row at a time only requires setting one row of nozzles with air outlet hood, which has a simple structure and good use effect. BRIEF DESCRIPTION OF THE DRAWINGS
