What is plastic Pall Ring?

plastic pall ring

Plastic Pall ring is a kind of chemical filler, mainly used in the field of gas absorption, separation and purification. Below, we will explain it in detail. Plastic Pall ring is an improvement on the basis of Lacey ring. Rasping ring is a kind of widely used filler with good performance. Due to its structural characteristics, there are some defects in fluid mechanics and mass transfer performance. In order to improve the performance of the filler, the plastic Pall ring was born. The plastic Pall ring is characterized by its special structure. It is formed by opening eight layers of rectangular small Windows on the side wall of the common rasi ring, and the small window blades overlap in the center of the ring, and the upper and lower surface layer Windows intersect with each other. This structure makes the gas distribution in the packing layer more uniform, increases the specific surface area of the packing, and improves the mass transfer efficiency of the packing. Plastic Pall ring has been widely used in low temperature distillation, absorption and scrubber in petroleum, chemical, chlor-alkali, gas, environmental protection and other industries because of its good mass transfer and fluid dynamics properties. At the same time, it is also suitable for ozone contact reactor, carbon dioxide degassing tower acid mist purification tower and other reaction towers or contact packing. In these applications, the main role of plastic Pall rings is to increase the uniformity of gas distribution in the packed tower, and improve the mass transfer efficiency and separation effect of the packed tower. Due to its excellent mass transfer and fluid dynamics performance, the processing capacity and separation effect of the packed tower have been greatly improved.
