What is the cause of the blocked air outlet of the FRP purification tower ?
If the catalyst is the main reason for clogging the purification tower, you can stop adding such catalysts and use high-efficiency desulfurization catalysts that have a scrubbing effect. If the tower's packing plugs are mechanical impurities or all salts, the resistance of the tower cannot be reduced, but if the sulfur and salt mixture, after the sulfur is washed out, the salts will gradually disintegrate and loosen.
The regeneration tank continuously (or intermittently) overflows the sulfur foam into the foam pool, and the recovered residual liquid is settled before being used in the system to strengthen the pre-purification treatment of the water quality of the cooling tower and semi-water gas. Increase the amount of water on the scrubber before desulfurization.
Start electrostatic decoking to reduce the content of coal dust particles and tars that are substituted into the desulfurization system. In order to maintain the production progress, citric acid can be added to the desulfurization solution to slow down the upward trend of resistance. The amount of citric acid added is 10Kg / 100M3 each time.
