Cartridge dust collector is a kind of high-efficiency and energy-saving dust purification equipment. It has the characteristics of stability and reliability, low energy consumption and small footprint, and is especially suitable for dealing with flue gas with large air volume. This filter cartridge dust collector is widely used in dust removal in industries such as mechanical processing, chemical production, powder recycling, construction manufacturing, pharmaceutical production, food company production, furniture production, and hardware and electronic processing. It is mainly composed of the following main structures: modular frame structure, fan power unit, pulse blowback structural unit, filter cartridge filter structural unit, dust collection structural unit, etc., and its various components; Highly demanding working conditions.
Working principle of filter cartridge dust collector:
1. Connect the power supply and compressed air, press the switch button, the induced draft fan starts, and the dust collector starts to work.
2. The laser cutting smoke and dust splashed by sparks enter the air inlet of the dust collector under the power of the induced draft fan.
3. After passing through the air inlet, the sparks and dust first enter the spark catcher. Its labyrinth structure principle allows the sparks to collide with each other for many times and automatically extinguish, and finally fall into the ash hopper.
4. Then enter the surface of the filter cartridge, due to the sudden expansion of the airflow section and the action of the airflow distribution plate, the wind speed drops suddenly, and some coarse particles in the airflow collide with each other under the action of wind force and inertial force, and naturally settle to the bottom ash collecting hopper; Fine, low-density dust particles are deposited on the outer surface of the filter material of the filter cartridge through the combined effects of diffusion and sieving and are intercepted.
5. The clean gas penetrates the filter material, is discharged from the inner wall of the filter cartridge, and enters the clean room.
6. The air in the clean room is drawn out by the fan and discharged directly into the workshop without a chimney.
7. The resistance of the filter element filter cartridge increases with the increase of the thickness of the dust accumulation layer on the surface of the filter material.
8. The injection control methods can be divided into differential pressure control, sequence control and manual control. The pointer differential pressure meter will monitor the differential pressure of the filter cartridge in real time, which is intuitive and readable. The pulse controller will automatically open and close the valve, and open the compressed air to blow and clean the dust.
9. At this time, the pulse power supply is switched on instantly, the electromagnetic pulse valve is opened, and the compressed air with a pressure of more than 4 kg is instantly introduced into the surrounding air as a sufficient air source for secondary amplification, and is injected into the filter cartridge by high-pressure injection. The pleated filter cartridge instantly expands, deforms and bulges, resulting in vibration. Under the action of high-pressure pulse air flow, the dust attached to the outer surface of the filter cartridge is swept away and falls into the ash hopper at the bottom of the dust collector to collect dust. in the dust box.
10. After the cleaning is completed, the electromagnetic pulse valve is closed. After the dust on the surface of the filter material is removed, the resistance becomes smaller, the filter material is regenerated, and the function of intercepting dust is restored again. When the resistance rises, it will automatically cycle the cleaning and regeneration work again.
