Dusty gas is filtered by filter cartridges, and clean air is discharged by the induced draft fan. After the dust collector operates for a period of time, the dust on the filter cartridges gradually increases, causing the filter bag resistance to rise, requiring cleaning. The dusty gas enters the dust collector housing through the air inlet, first passing through the straightening plate. The dusty gas is evenly dispersed around each filter cartridge. Due to the multiple effects of the filter cartridge, it is blocked on the outer wall of the filter cartridge. The purified gas is discharged through the filter cartridge and the outlet of the housing.
While meeting the requirements of the production process, the improvement of the work area environment mainly considers several aspects: the working environment of the polishing workers, the reliable operation of the equipment, and the convenience of operation and maintenance.
Mainly used in furniture manufacturing, medicine, food processing, metallurgy, chemical industry, machinery manufacturing, casting and other industries. After the dust-laden gas is filtered by the filter cartridge, the clean air is discharged by the induced draft fan. After the dust collector works for a period of time, the dust on the filter cartridge gradually increases, causing the filter bag resistance to rise, and needs to be cleaned. The dust-laden gas enters the dust collector box from the air inlet, and first passes through the straightening plate, and the dust-laden gas is evenly dispersed.
To each filter cartridge. Due to the multiple effects of the filter cartridge, it is blocked on the outer wall of the filter cartridge. The purified gas is discharged through the filter cartridge and the outlet of the box. With the increase of the service time, the dust adsorbed on the surface of the filter cartridge gradually increases, the air permeability of the filter cartridge weakens, and the resistance of the dust collector increases continuously. In order to ensure that the resistance of the dust collector is controlled within the specified range, the pulse control instrument sends a signal to sequentially open the pulse solenoid valve, so that the compressed air is sprayed from the nozzles of the spray pipe to the corresponding filter cartridge, causing the instantaneous gas expansion in the filter cartridge, so that the dust accumulated on the outer wall of the filter bag falls off and enters the ash hopper.
