Selection of PPH packing absorption tower

Selection of PPH packing absorption towerworking principle

The exhaust gas is introduced into the bottom of the tower by a fan, evenly dispersed by a gas distribution device, and then passes through the packing layer from bottom to top. The top spray system sprays the absorbent onto the surface of the packing, forming a uniform liquid film that flows down along the gaps between the packing. When gas flows through the gaps of the packing, it fully contacts with the liquid film and undergoes absorption or neutralization reactions, transferring pollutants to the liquid phase. The purified gas is collected by a demister and discharged from the tower, while the absorbing liquid is recycled or regularly replaced.

Application advantages

Corrosion and temperature resistance: PPH material has strong corrosion resistance and better temperature resistance than traditional materials such as PP, PVC, PE, etc., making it suitable for high-temperature exhaust gas treatment.

Efficient and energy-saving: The gas-liquid contact is sufficient, the mass transfer efficiency is high, and the operation flexibility is large, which can adapt to different air volumes and pollutant concentrations.

Long lifespan: The material has strong oxidation resistance, and the outer layer is added with ultraviolet absorbers, resulting in a long lifespan for both indoor and outdoor use.

Flexible design: The exterior and interior structure can be customized according to working conditions such as space, air volume, air pressure, and absorption efficiency to ensure effective treatment.

Stable operation: No vulnerable parts, no need for frequent replacement of parts, and stable operation, reducing manual care costs.
