Antioxidant measures of pps dust filter bag

What are the antioxidant measures of pps dust filter bag?

1. Establishment and maintenance of protective layer

Direct contact with the dust filter bag is an effective means to block the flue gas.

(1) Dust-proof layer: The filtration of dust-containing gas is mainly carried out through the dust layer. The effect of the primary dust layer is much larger than that of the filter cloth. While improving the dust-removing efficiency, it directly decomposes and isolates the smoke and filter bags to protect the dust-removing filter bags. Therefore, by protecting the dust layer, the filter bag can be protected from damage.

(2) Surface treatment of filter material: After the filter bag is treated on a certain surface, it will directly affect the harmful components (including oxygen) and filter material in the flue gas, causing damage.

2. Reduce the oxygen content and dosage of compressed air

The oxygen content in the air is 21%, which is at a relatively high level. Therefore, reducing the oxygen content of this part is an important aspect.

1) Using low-oxygen dust removal compressed air source: using compressed nitrogen dust removal, the oxygen content in the flue gas will not increase or decrease.

2) The method of using high compressed air.

3) Reduce the number of jets: The differential pressure control method is generally more scientific than sequential control, which can reduce the number of pulsed jets. Fewer jets means less compressed air.

4) Reduce the residence time of compressed air: in online ash cleaning, the residence time of compressed air is less than 1 second, and it can reach several minutes in offline mode, shortening the reaction time.

Reduce air leakage rate: Improve production installation quality and sealing effect, reduce air mixing.
