Pall Ring Packing

Pall ring is a kind of metal filler, which is an annular piece processed by seamless steel pipe, with a flat cross section and a wave shape in the middle. Its advantage is that the plug hole between the fillers is enhanced to form a large surface area, which can better improve the contact between the material and the filler, and increase the speed and mass transfer coefficient. At the same time, because the Pall rings are evenly distributed, the fluid distribution is more reasonable, which is conducive to uniform flow in the reactor and promotes the reaction process. Due to its good strength, corrosion resistance, high temperature resistance and large surface area, it is widely used in various chemical reactors and separation towers, such as in the chlor-alkali industry.

Metal Pall Ring Apply Effect

In the chlor-alkali industry, the electrolytic cell using Pall ring packing enhances the contact between liquid and gas, which can effectively improve the stability and rotation speed of the reactor, increase the electrolysis efficiency and speed, and reduce chemical consumption and energy consumption.Moreover, the Pall ring provides a larger surface area, which is beneficial to the treatment of pollutants and waste water, so as to achieve the purpose of environmental protection and energy saving.
