PPH Exhaust Gas Purification Tower

China supplier Xinda Chemical’s PPH exhaust gas purification tower is specially designed for treating high-concentration acid and alkali corrosive waste gas. The tower body is made of high-crystalline polypropylene homopolymer (PPH) through a spiral extrusion and full-piece winding process, with no welds throughout. It has excellent sealing performance and corrosion resistance, and can withstand the erosion of strong media such as sulfuric acid, nitric acid and hydrofluoric acid for a long time.

Its internal highly efficient packaging and spray system can achieve a purification efficiency of over 99%.It is compact and easy to install and maintain.The equipment can be adjusted flexibly according to the composition of the exhaust gas and the air volume to be treated.It is widely used in industries such as chemicals, electronics, metallurgy, and pharmaceuticals, and is a reliable choice for achieving stable compliance emissions and reducing long-term operating costs.

PPH exhaust gas purification tower vs traditional FRP tower

Compared with the traditional FRP exhaust gas purification tower, our PPH exhaust gas purification tower has obvious advantages in a number of core performances.

Firstly, in terms of materials and craftsmanship, the PPH tower is integrally formed without any splicing welds or leakage points. However, FRP towers are usually made by hand in multiple layers, posing potential defect risks such as delamination and pinholes.

Secondly, in terms of corrosion resistance and service life, PPH materials have more balanced resistance to mixed chemical media, slower overall aging speed and longer service life.The corrosion resistance of glass fiber reinforced plastic (FRP) largely depends on the

proportion of resin and construction quality.In complex working conditions, leakage, bulging and other problems may appear earlier.

Finally, in terms of physical performance and maintenance, PPH material has good toughness, impact resistance, not easy craze, smooth surface, not easy scaling, make it easier to maintain and clean.FRP material is relatively rigid, impact resistance is poor, the rough wall are more likely to accumulate dirt.Therefore, PPH exhaust gas purification towers are usually more reliable in terms of long-term use, safety and overall economy.

Typical Application Scenarios

Core features and advantages

Strong corrosion resistance: our PPH exhaust gas purification tower can withstand sulfuric acid, nitric acid, hydrochloric acid and other strong acid and sulfur oxide (SOx), nitrogen oxide (NOx) and other corrosive gases, suitable for high concentration, high temperature (long-term use temperature -20℃ to 100℃) of the harsh conditions, performance is better than ordinary PP material.

Excellent structural stability: the spiral extrusion and winding process is used for one-time molding, and the weld-free design eliminates the leakage risk of traditional welding, and improves the tightness and compressive strength of the equipment.

High purification efficiency: through the customized packing and liquid circulation system, the exhaust gas and absorption liquid are fully in contact, the removal rate of hydrogen sulfide, ammonia and other harmful substances can reach more than 95%, to ensure that the emission standards.

Economy and practicality: It is lightweight, easy to install and maintain, occupies a small area, and has a manufacturing cost lower than that of materials such as stainless steel and fiberglass reinforced plastic. Its service life is over 10 years.
