Description
Technical Field
The utility model relates to an industrial waste gas treatment equipment technical field, concretely relates to HES series exhaust purification tower.
Background
The HES series waste gas purifying tower is a device for treating industrial waste gas, and is suitable for industries such as chemical industry, chemical preparations, pharmaceutical factories, laboratories, metallurgy, light industry, food, new energy, electroplating, acid cleaning, petroleum, machinery, electric power and the like.
Waste gas enters the tower from an air inlet arranged at the lower part of the side wall of the purification tower, passes through the packing layer, is subjected to gas-liquid two-phase full contact absorption with absorption liquid, is dehydrated through the defogging layer after being purified, is discharged through an air outlet arranged at the top of the tower, and is discharged into a chimney through a fan. The absorption liquid is sprayed down at the tower top after being pressurized by a water pump at the tower bottom, and finally flows back to the tower bottom for recycling, and the purified waste gas reaches the standard and is discharged.
When the spray tower commonly used at present is used for treating waste gas under certain specific working conditions, certain problems still exist, and the concrete steps are as follows:
