BLM38 pulse drum dust filter is a unit combination dust removal equipment with high air volume, low filtering air speed, good dust removal effect, high dust removal efficiency, reliable operation, easy maintenance, and small footprint. Modular production with stable quality. Widely used in industries such as grain processing, building materials, and chemical engineering for smoke dust removal, material recovery, and dust control.
Working principle of BLM38 pulse drum dust filter: Dust containing gas enters the middle and lower boxes through the dust collector inlet, and during the process of entering the upper box through the filter bag, the dust and gas are separated due to various effects of the filter bag. The dust is adsorbed on the filter bag, while the gas passes through the filter bag and enters the upper box through the Venturi tube, and is discharged from the outlet. During the process of purifying dusty gases through filter bags, more and more dust accumulates on the filter bags over time, causing the resistance of the filter bags to gradually increase and the amount of gas passing through them to gradually decrease. In order to ensure the normal operation of the dust collector, the resistance should be controlled within a limited range (generally 1176-1471Pa). Spray cleaning is a process in which the control instrument sends instructions to trigger each control valve in sequence, opening the pulse valve. The compressed air in the air bag is sprayed into the corresponding filter bag through the Venturi tube with each aperture of the spray pipe, and the filter bag is reused. The cleaned dust falls into the ash hopper and is discharged from the machine through the ash discharge system. Due to the regular cleaning of dust accumulated on the filter bag, the purified gas can pass through normally to ensure the normal operation of the dust collector. The cleaning pulse is controlled by electric and pneumatic means, and the cleaning time and interval time can be adjusted.

Technical parameters of BLM38 pulse cloth tube dust filter: The calculation of processing air volume and equipment resistance are two related parameters, and are related to physical parameters such as dust concentration, humidity, viscosity, etc. of the inlet air. Reference values for air network design: dust concentration of 2g/m3, processing air volume of 9000-10000m3/h, equipment design resistance of 70-80mmH2O. Generally, for dust with high dust concentration, temperature, and viscosity, the equipment resistance should increase under the same processing conditions. When the inlet air dust concentration is high or the dust humidity is high, the processing air volume should be taken as a small value. When the inlet air dust concentration is low or the viscosity is low, the processing air volume can be taken as a large value. This is for reference only.
