What methods can be used for P84 filter bags to alleviate corrosion problems?

1. The high-temperature-resistant dust-removing cloth bag is suitable for corrosion-resistant filter materials containing dust and gas components;

2. P84 filter bag should take heat preservation and heating measures to prevent condensation. The working temperature of the dust collector should be 15 higher than the dew point temperature.

3. The filter bag frame and anti-shrinking ring contacted by the P84 filter bag should be made of corrosion-resistant needle filter felt, or take anti-corrosion measures for the P84 filter bag.

4. The dust removal equipment and system should be kept tight, and the air leakage rate should be kept low.

5. Wet or wet raw materials and fuels in the rainy season must not enter the furnace to avoid excessive moisture in the high-temperature flue gas.

6. Check the air supply system of the air compressor of the vacuum cleaner. If there is no air dryer, it must be configured. Both process gas and instrument gas require dry and clean air sources to ensure the normal operation of the equipment. At the same time, during the operation of the dust collector, regularly check the quality of the air source, and promptly eliminate the problems found.

7. The P84 filter bag should be inspected and replaced in time for the sealing strips of the six air chamber doors on the top of the vacuum cleaner to prevent external moisture and cold air from entering the air chamber.
