In industrial production processes, waste gas emissions have always been a significant challenge for enterprises. With increasingly stringent environmental policies, the efficient and safe treatment of industrial waste gas has become crucial for sustainable development. Among various waste gas treatment devices, Packed Absorption Towers are increasingly favored by enterprises due to their high absorption efficiency and strong organic gas treatment capabilities.
Packed absorption towers are commonly used gas-liquid contact devices, widely applied in industrial waste gas treatment, chemical processes, and air pollution control. Their core working principle is gas-liquid absorption: the uniformly arranged packing material within the tower allows for full contact between the gas and liquid, achieving the transfer of pollutants from the gas phase to the liquid phase.
Specifically, waste gas enters from the bottom of the tower and comes into contact with the absorbent liquid flowing downwards. The large surface area of the packing material provides abundant gas-liquid contact interfaces, allowing harmful components in the waste gas to be absorbed by the absorbent liquid, achieving gas purification. During the reaction process, the absorbent liquid may undergo physical absorption or chemical reaction with pollutants, thereby enhancing waste gas treatment efficiency.
The packing material is randomly packed, with a simple structure, suitable for treating waste gases with large fluctuations in gas volume.
The packing material is regularly arranged, resulting in low pressure loss and high mass transfer efficiency, suitable for high-requirement industrial gas treatment.
Equipped with an internal spray system, improving the uniformity of liquid distribution and enhancing gas-liquid contact efficiency.
The Group is a leading manufacturer of gas absorption towers and custom-packed absorption towers in China, holding multiple qualifications including National High-Tech Enterprise certification, Zhejiang Provincial Science and Technology Enterprise certification, and a regional R&D center. The Group holds over 30 utility model patents, numerous invention patents, and software copyrights.
