Hongpan HPPL3893 PP water spray tower PP water spray tower waste gas collection and treatment

Spray towers are environmental protection equipment that purify waste gas through gas-liquid contact. They are mainly used to treat acidic gases (such as SO?, HCl), alkaline gases (such as NH?), dust and organic pollutants in industrial waste gas. Its English names include:

 Spray Tower?

Scrubber? (scrubber tower) 

Spray Column? (spray gas scrubber)

Core functions ?

Neutralization reaction ? : Neutralizing harmful components in waste gas by spraying acid or alkali solutions (such as treating acid mist with NaOH)

Dust removal and cooling ? : Remove particulate matter and lower the temperature of high-temperature flue gas (100-200 ° C)

Odor control ? : Absorb water-soluble malodorous substances (such as H?S, VOCs)

Structure and composition ?

Tower body ? : Corrosion-resistant materials (fiberglass reinforced plastic, PP, stainless steel), vertical/horizontal design

Spray system ? : nozzles (spiral/solid cone), circulation pump and piping

Packing layer ? : Packing such as Pall rings to increase the gas-liquid contact area (specific surface area ≥200m2/m3)

Demister ? : Folded plate or wire mesh structure for separating droplets from purified gas

Working principle ?

Waste gas enters from the bottom of the tower and comes into countercurrent contact with the absorption liquid sprayed from the top in the packing layer. Pollutants are removed through absorption, reaction or sedimentation. The purified gas is dehydrated by a demister and then discharged.

Technical advantages ?

High efficiency purification ? : Absorption rate of ≥95% for pollutants with Henry coefficient >0.1

Strong adaptability ? : Capable of handling waste gas with air volume ranging from 3000 to 100,000 m3/h

Low maintenance ? : No internal components, not prone to clogging

Application fields ?

It is particularly suitable for the treatment of acid mist waste gas in industries such as chemical engineering, metallurgy, pharmaceuticals, and waste incineration
