Ceramic Structured Packing
Ceramic structured packing is a kind of column shape and single layer corrugated packing, consisting of many moire pieces with the same geometric shape and parallel to each other. According to the different obliquity of corrugated sheet, this product is divided into X-style and Y-style, and X and Y correspond to the 300 and 450 respectively. Ceramic structured packing has a series of advantages, such as high efficiency, low pressure drop, great treatment, little liquid content, unremarkable amplifying effect and high elasticity in operation. With a unique structure, and excellent hydrophilic performance, the very thin liquid film can be formed in the surface of ceramic, and the flow of liquid film as well as oblique and flexural channel ensure the smooth airflow, and don’t impede it, making the efficiency of this product comparable with metallic corrugated packing. Yuanying makes the production of different specific surface area and flexible standard structured packing in terms of customer's demands.
Ceramic structured packing is not only widely used in coal gas washing tower, fertilizer heat gas saturation tower, naphthalene washing tower, ammonia washing tower, but also as the support for heat exchange machine , catalyst, and suit for a big tower rebuilding/revamp.
