What Is a PPH Falling Film Type Absorber?

A PPH Falling Film Type Absorber is a specialized industrial gas treatment device designed to remove harmful gases from industrial exhaust streams. The system works by allowing absorption liquid to flow downward as a thin film along the inner surface of the absorber while contaminated gas flows through the equipment.

This falling film design significantly increases the contact area between the gas and liquid, improving mass transfer efficiency and maximizing purification performance. Because the equipment is manufactured using PPH material, it also offers exceptional resistance to acid and alkaline corrosion.

The PPH Falling Film Type Absorber is commonly used for handling gases such as:

  • Hydrochloric acid gas (HCl)
  • Sulfur dioxide (SO2)
  • Ammonia gas (NH3)
  • Hydrogen fluoride (HF)
  • Nitric acid mist
  • Organic exhaust gases

How Does a PPH Falling Film Type Absorber Work?

The operating principle of the PPH Falling Film Type Absorber is based on gas-liquid countercurrent contact. The absorption liquid forms a uniform thin liquid film on the surface of the absorber, while exhaust gas moves upward or through the system. Pollutants are absorbed into the liquid and neutralized through chemical or physical reactions.

Component Function
Gas Inlet Introduces contaminated industrial gas
Liquid Distributor Creates uniform falling liquid film
Absorption Area Allows efficient gas-liquid contact
PPH Tower Body Provides corrosion-resistant structure
Gas Outlet Releases purified gas safely

Thanks to this design, the PPH Falling Film Type Absorber achieves excellent purification efficiency while reducing operational resistance and energy consumption.
