PPH Multi-Function Exhaust Gas Purification Tower

The PPH multi-function exhaust gas purification tower of Xinda Chemical from China is specially designed for treating complex mixed industrial waste gas. The main body of the equipment is made of high-crystalline polypropylene homopolymer (PPH) in one piece. The tower body has no welds and has excellent corrosion resistance. It can withstand the combined erosion of various media such as hydrochloric acid, sulfuric acid mist, ammonia gas and some organic solvents for a long time.

Its interior adopts a modular design, which can integrate multiple purification units to achieve efficient and staged removal of acidic, alkaline and some organic waste gases, with a purification efficiency of 95% to 99%.The tower has compact structure, light weight, convenient transportation and installation, low operation and maintenance cost and long service life. It is an efficient and economic solution for the petroleum chemical industry, medicine, electroplating, metallurgy and other industries to achieve stable emission standards of waste gas.

Main working mechanism

Our PPH multi-function exhaust gas purification tower achieves exhaust gas purification through the synergistic effect of physical adsorption, chemical absorption and spray contact. The process is as follows: The waste gas enters from the bottom of the tower and flows upward in countercurrent, fully contacting with the chemical liquid sprayed by the spray system in the packing layer. Harmful substances are removed through dissolution (such as acid mist), neutralization reaction (such as acid and alkali waste gas), or adsorption (such as particulate matter). The purified gas is discharged after dehydration treatment, while the waste liquid is discharged from the bottom of the tower and recycled.

Key technical points

Gas-liquid contact enhancement: By increasing the contact area through the porous structure of fillers (such as environmentally frien dly fillers, plastic fillers, etc.), and in combination with the atomization effect of the spray system, the mass transfer efficiency is improved.

Centrifugal separation assistance: Part of the tower body design uses the centrifugal force generated by the rotation of the exhaust gas to swing the fog droplets and particles to the tower wall, reduce the flow of water mist, and further improve the purification effect.

Material Properties of PPH

Structural design advantages

Compact and efficient: Our PPH multi-function exhaust gas purification tower includes vertical or horizontal structural designs, occupies a small area, and is suitable for working conditions with limited space.

Modular configuration: The type of packing, the number of spray layers and the type of liquid medicine can be customized according to the components of the exhaust gas (such as acid mist, VOCs), with strong flexibility.

Low maintenance cost: The automated sprinkler system is easy to operate, and the PPH material is wear-resistant, reducing the need for component replacement.
