The domestically produced pulse type backwash self-cleaning air filter is effective for 2 μ The particle filtration efficiency is greater than 98%; The initial resistance is less than 150Pa, the normal resistance is 400-600Pa, the alarm resistance is 800Pa, and the maximum safety resistance is 1500Pa; Blowback compressed air pressure is 600-800kPa, and the flow rate is less than 0.15m3/min. The effective filtration area of each filter cartridge is 21.4m3.
The advantages of pulse backwash self-cleaning air filters include:
1. The filter cartridge has high filtration efficiency, low resistance, long service life, and can resist water mist;
2. Automatically blow back to clean dust, achieving self-cleaning. It can ensure uninterrupted operation of the air compressor for more than 2 years. Experimental results have shown that centrifugal air compressors operating continuously for 5-10 years have no obvious scaling inside, and there are no traces of dust wear on the blades;
3. Equipment maintenance is convenient and cost-effective. The filter cartridge has a long lifespan, is easy to replace, and can be replaced without stopping the machine. The filter material is high-quality waterproof paper material, which is cheap in price;
4. The pulse backwash self-cleaning air filter is a dry air filter. Compared with a wet air filter, the processing air does not contain oil and does not pose a threat to the safety of the air separation device.
