How Does Chromic Acid Mist Recovery Equipment Work?
The working principle of chromic acid mist recovery equipment is based on mist collection, condensation recovery, and exhaust purification.
During chrome plbating operations, chromic acid mist is generated due to solution agitation, electrochemical reactions, and airflow disturbance above the plating tank.
Because chromic acid mist has high density and good condensation characteristics, the recovery system can effectively capture and recover mist particles through controlled airflow and filtration technology.
Chromic Acid Mist Collection and Recovery System
The chromic acid mist generated during the plating process is collected by the induced draft system and transferred into the recovery equipment.
Inside the recovery unit:
The induced fan guides chromic acid mist into the recovery chamber.
Multi-layer interception filters capture and condense mist particles.
The condensed chromic acid liquid flows along the filter surface into the recovery tank.
The recovered solution is collected and returned to production according to process requirements.
This recovery process helps reduce chemical waste and improves the utilization efficiency of chromic acid resources.
Spray Purification Scrubbing System
After chromic acid mist recovery, the remaining exhaust gas enters the spray purification tower for further treatment.
The system adopts a packed-bed scrubbing structure. During operation, the scrubbing liquid is evenly sprayed onto the surface of the packing layer through nozzles.
When exhaust gas passes through the fully wetted packing layer:
Pollutants contact with the scrubbing solution.
Physical and chemical absorption reactions remove remaining pollutants.
The saturated gas passes through the demister to remove excess moisture.
The purified exhaust gas can be discharged according to applicable environmental requirements.
The purification system improves exhaust treatment performance and provides additional protection for the working environment.
