Pretreatment equipment–spray purification tower

Product Description

As a type of air pollution control device, the spray tower (or spray scrubber) is an indispensable tool in modern industrial environments. It can remove pollutants from exhaust gas and reduce the impact on the environment.

Working Principle of Spray Tower

Dust-laden and pollutant-containing waste gas enters from the lower part of the tower body. After preliminary treatment, it fully contacts with the atomized droplets sprayed by the spraying system. In this process, dust particles, gaseous pollutants, etc. in the waste gas are absorbed, intercepted and condensed by the droplets.

Then, the waste gas passes through the packing layer to further increase the contact area and contact time with the droplets and improve the purification efficiency.

Finally, the waste gas after demisting treatment is discharged from the top of the tower body to meet environmental protection standards.

Applications of Spray Tower

The spray purification tower is widely used in waste gas treatment in industries such as chemical, electronics, metallurgy, electroplating, pharmaceuticals, printing and dyeing.

Product Name

Spray tower is a kind of waste gas treatment equipment, also called waste gas tower, purification tower, spray scrubber. This technology plays a crucial role in improving air quality and ensuring compliance with environmental regulations by efficiently eliminating harmful contaminants before they are released into the atmosphere.

The spray purification tower is mainly composed of tower body, packing layer, spraying system, demister, circulating water tank and other parts.

Tower body: Usually cylindrical or square, made of corrosion-resistant materials such as fiberglass reinforced plastic, stainless steel, etc., which can withstand the pressure of exhaust gas and the corrosion of spraying liquid.
Packing layer: Located inside the tower body. The packing can be in various shapes such as spherical, annular, corrugated plate, etc. Its function is to increase the contact area and contact time between exhaust gas and spraying liquid and improve the purification efficiency.
Spraying system: Composed of spraying pump, pipeline, nozzle, etc. It pressurizes circulating water or specific absorption liquid and sprays it evenly on the packing layer to fully contact with exhaust gas and absorb pollutants therein.
Demister: Installed at the top of the tower body, it is used to remove tiny liquid droplets carried in exhaust gas and prevent liquid droplets from being carried out of the purification tower and causing secondary pollution.
Circulating water tank: Located at the bottom of the tower body, it is used to store spraying liquid. After treatment, it is recycled to save water resources.
