Silo top pulse bag filter
Bag dust collectors are widely used in industrial sectors such as mining, metallurgy, machinery, building materials, chemical, and light industries. Its working principle is that when dust-laden gas passes through the filter bags inside the bag dust collector, due to the filtering effect, only the gas passes through, while the dust is retained on the surface of the filter bags, achieving the purpose of dust removal. Compared with other dust collectors, bag dust collectors have the advantage of higher filtration efficiency, generally above 99.99%. Therefore, the gas discharged from the dust collector contains less dust and can meet the requirements of environmental emission standards; when the filtration velocity is selected appropriately and the cleaning method is proper, changes in the inlet dust concentration have little impact on dust removal efficiency and pressure loss; the equipment has high operational stability and strong adaptability; it facilitates the recovery of useful materials and enables comprehensive utilization.

Main application scenarios:
Bag filters are widely used in industrial sectors such as mining, metallurgy, machinery, building materials, chemical industry, and light industry. Their working principle is that when dust-laden gas passes through the filter bags inside the bag filter, due to filtration, only the gas passes through, while the dust is blocked on the surface of the filter bag, achieving the purpose of dust removal. Compared with other dust collectors, the bag filter has the advantage of higher filtration efficiency, generally at 99.99% and above. Therefore, the gas discharged from the dust collector contains less dust and can meet
the requirements of environmental emission standards; when the filtration velocity is properly selected and the ash cleaning method is appropriate, changes in the inlet dust concentration have little effect on dust removal efficiency and pressure loss; the equipment has high operational stability and strong adaptability; it is convenient for recycling useful materials and achieving comprehensive utilization.
Function Introduction ：
Driven by the fan, a negative pressure environment is formed inside the bag filter, in the dust removal pipes, and at the dust hood opening, allowing dust from the dust source to enter the dust collector under the action of pressure difference. After the dust-laden gas enters the dust collector from the inlet, the airflow speed slows down, coarse particles separate from the airflow and settle in the dust collection chamber, fine dust is blocked on the outer surface of the filter bag as it passes through with the airflow, and clean gas is discharged from the outlet. ; When the dust layer on the filter bag surface is thick, the pulse controller sends a command to open the blow-off valve, and the compressed air in the air bag
is ejected at high speed through the blow pipe, simultaneously inducing several times the volume of surrounding air into the filter bag, which then rapidly ejects from the inside out, blowing the dust from the outer surface of the filter bag into the dust collection chamber, finally discharged through the ash discharge hopper. The dust collector uses pulse jet cleaning, which achieves thorough cleaning without damaging the filter bags, thus ensuring their service life. The cleaning process is automatically controlled by the pulse controller and can use pressure difference control or time control.
