Working principle of the top dust collector in the warehouse

The dusty gas enters the dust collector box through the air inlet, and small dust particles are trapped on the outer wall of the bag due to various effects of the bag. The purified gas is discharged through the air outlet of the box on the cloth bag. As the usage time increases, the amount of dust adsorbed on the surface of the bag increases, the breathability of the bag decreases, and the resistance of the dust collector continues to increase. To control the resistance of the dust collector within a limited range, a pulse controller sends a signal to sequentially open the electromagnetic pulse valve, causing the compressed air in the air bag to be sprayed from each nozzle of the blowing tube to the corresponding Venturi tube (called primary air), and inducing the surrounding air (called secondary air) with a derivative multiple of the primary air to enter the filter cartridge when the high-speed airflow passes through the Venturi tube, causing rapid expansion between the bags. Due to the impact of the reverse pulse airflow, the bags quickly disappear, and the bags shrink sharply, causing the dust accumulated on the outer wall of the bags to be trapped and the falling dust to enter the ash storage.

Eight advantages of warehouse top dust collector

1. High processing air volume: The air volume of the top dust collector can be set to over 50000, and the processing air volume is particularly large.

2. Low operating resistance: As the dust adsorbed on the surface of the bag increases over time, the resistance of the dust collector will continue to increase. In order to control the resistance of the dust collector within a limited range, a pulse control device sends a signal to sequentially open the electromagnetic pulse valve, so that the compressed air in the air bag is sprayed from each spray hole of the spray pipe to the corresponding Venturi pipe (called primary air), and when the high-speed airflow passes through the Venturi pipe, it induces several times the surrounding air of the primary air (called secondary air) to enter the filter cartridge, causing rapid expansion between the bags. Due to the impact of the reverse pulse airflow, it quickly disappears, and the bag shrinks sharply. This causes the dust accumulated on the outer wall of the bag to be blown by the falling dust. Enter the ash storage.

3. Save space: Due to its simple design, the top dust collector has a smaller volume, saving a lot of space.

4. Easy operation and maintenance: The internal structure of the top dust collector is not complicated, the disassembly is simple, and the operation method is also not complicated.

5. The dust removal efficiency of the warehouse top dust collector can achieve dust removal

6. Wide application: Warehouse top dust collectors can be used in industrial and mining enterprises such as cement, mineral powder, mining, metallurgy, building materials, machinery, chemical industry, grain processing, etc. And it is widely used to filter small, non fibrous dry dust in gases or to recover dry powders in process flows.

7. Stable operation: The working principle of the top dust collector in the warehouse is simple, and its operation is also relatively stable.

8. Good sealing: The dust collector on the top of the warehouse operates all filtering processes internally, with minimal impact on the external air and excellent sealing.
