Adsorption:
After passing through a filter to remove solid particulates, the organic waste gas enters the adsorption tank from the top. Organic compounds are captured, adsorbed, and concentrated by the activated carbon, while the purified air is discharged into the atmosphere from the bottom of the tank via the main fan.
Condensate Purification:
To ensure the cleanliness of the condensate and prevent organic solvent-laden water from being discharged into water bodies, compressed air is injected into the water after separation. This process effectively strips away any remaining organic solvents. The air-now containing the organic compounds displaced by the compressed air-is routed back to the waste gas system for re-adsorption. The purified condensate is then discharged into the sewer system.
Continuous Adsorption Measures:
In facilities with continuous production processes, the adsorption system must also operate continuously. Consequently, the waste gas purification system can be designed with a dual-tank configuration, allowing for alternating and continuous cycles of adsorption and regeneration.
