Bag dust collector

The working principle of a pulse bag dust collector is to enter the dust containing gas into the ash hopper through the air inlet or into the filter bag room through an open flange. The dust containing gas passes through the filter bag as clean gas and enters the clean gas room. It then passes through the exhaust port of the clean gas room and is discharged by the fan. Dust accumulates on the outer surface of the filter bag and continues to increase, causing the resistance of the pulse bag dust collector to continuously increase. In order to ensure that the equipment resistance does not exceed 1200pa and the pulse bag dust collector can continue to work, it is necessary to regularly remove the dust on the filter bag. Ash cleaning is a process in which a pulse valve is activated in a timed sequence controlled by a program, causing compressed air inside the air bag to be sprayed out through the orifice of the blowing tube and induced by a venturi tube to enter the filter bag, causing it to rapidly expand in an instant. With the reverse effect of the airflow, the dust is shaken off to achieve the purpose of ash cleaning.

When the dust containing gas passes through the filter cloth in the process of bag filter, the gaps between the filter cloth fibers or the gaps between the dust adsorbed on the surface of the filter cloth separate the dust larger than the diameter of the gaps, which is called screening effect. For the new filter cloth, due to the large gap between the fibers, this effect is not significant and the dust removal efficiency is also low. The screening effect is only significant when a certain thickness of dust layer is established on the surface of the filter bag after a certain period of use. After dust removal, due to a certain amount of dust remaining on the surface and inside of the filter bag, good dust removal efficiency can still be maintained. For needle punched felt or fluffy filter cloth, as the felt or fluffy filter cloth itself forms a thick porous filter layer, it can fully exert the screening effect and does not rely solely on the dust layer to maintain high dust removal efficiency.

The filter bag uses compressed air for blowing and cleaning, and the cleaning mechanism consists of an air bag, a blowing pipe, and an electromagnetic pulse control valve. The top of each row of filter bag outlets in the filtering room is equipped with a spray pipe, and the lower side of the spray pipe is directly facing the center of the filter bag with a spray port. Each spray pipe is equipped with a pulse valve and is connected to the compressed air bag. When cleaning, the electromagnetic valve opens the pulse valve, and compressed air is sprayed into the filter bag through the nozzle. Together with the surrounding gas it injects, it enters the inside of the filter bag, causing it to shake completely and forming a reverse blowing airflow from the inside out, removing dust attached to the outer surface of the filter bag and achieving the purpose of cleaning.

Pulse jet cleaning: This cleaning method has the highest cleaning kinetic energy applied to the dust layer and is a typical method of external filtration for cleaning. The fine dust force is very strong, and the residual amount of dust adhering to the yarn inside the dust removal bag is relatively small. The dust removal bag used is usually felt or needle punched felt. Under the action of pulse blowing, the dust removal filter bag undergoes significant instantaneous deformation and generates significant stress, so it is necessary to use filter materials with strong tensile resistance. Dust removal bags often rub against the skeleton, so wear-resistant dust removal filter bags should be used, and fabric dust removal bags can also be used.
