PP Hular Ring is a filler made of polypropylene (PP) material, which is similar in structure to Pall ring, but different in design. The design of PP Hular Ring has good gas-liquid contact area and fluid distribution effect, which improves the mass transfer efficiency. This design allows for better mixing of gases and liquids in the filler, resulting in improved separation and reaction efficiency. Due to its unique structure, PP Hular Ring can effectively reduce the pressure drop of the packed bed, thereby reducing energy consumption and improving the operating efficiency of the system. The high porosity of the filler ensures a large flow area, which allows for a more uniform distribution of gases and liquids, and improves the overall mass transfer performance. Polypropylene material has good corrosion resistance to a variety of acids, alkalis and chemicals, and is suitable for dealing with a variety of chemical media. PP Haier is lighter than metal filler, which is easy to transport and install, while also reducing the structural load. The lower cost of polypropylene makes PP Hular Rings economically advantageous and suitable for large-scale applications. The polypropylene material has a certain wear resistance, which makes the filler not easy to wear and prolongs the service life.

PP Hular Ring
It is used in chemical reactors, absorption towers, scrubbers and other equipment to improve the efficiency of gas-liquid mass transfer and carry out various chemical reactions and separation operations. It is used in petroleum refining, gas desulfurization, catalytic cracking and other processes to improve the quality and separation effect of petroleum products. In wastewater treatment, waste gas purification and other environmental protection devices, it is used to remove pollutants in wastewater or harmful substances in gases. Used as a packing material in heat exchange and cooling towers to help improve heat exchange efficiency and reduce energy consumption. With its excellent mass transfer performance, corrosion resistance and economy, PP Hular Rings perform well in many industrial applications that require efficient gas-liquid separation and mass transfer.
