Problems solved by technology

When the liquid is separated by rectification, one is that the packing strength of the ceramic corrugated plates is not high enough. When they are stacked together, the corrugated flow channels on the contact surface of the packing are straight and vertically staggered, so the flow direction of the liquid between the packing layers will change, so that the flow speed of the liquid between the packing layers will decrease and the flow resistance will increase. Large, resulting in uneven distribution of liquid flow on the entire packing layer, thereby reducing the separation effect of liquid rectification
Moreover, the flow direction of the liquid inside the existing corrugated structured packing is the same as the inclination direction of the corrugated plate, and the tendency of the liquid to flow in the up and down direction inside the packing is small, and the liquid cannot communicate with each other when the liquid is rectified and separated in the up and down direction between the corrugated packing. , the flow direction is relatively single, which also increases the flow resistance of the liquid, and the number of water points formed by the liquid inside the corrugated packing is less. Will reduce the separation effect of liquid distillation

Abstract

The invention discloses a streamlined ceramic crest structured ripple packing which comprises a main body (1); the main body is formed by superimposing ceramic plate elements (3); inclined raised lines (6) are arranged on each ceramic plate element at intervals; inclined grooves (2) are formed between the raised lines; a vertical passage (7) is arranged at two ends of the grooves positioned at the upper end of the main body as well as at two ends of the grooves positioned at the lower end of the main body; and the passages and the inclined grooves are in smooth connection; the main body comprises the following components in percentage by weight: 10-30% of Changning mud, 10-30% of Changning crude sandstone, 10-30% of Guangxi white mud, and 10-30% of Hunan spoil disposal. The packing has the characteristics of high strength, large bearing capacity, small pressure drop resistance and large porosity, so that when liquid is separated through rectification, the liquid flow resistance is reduced, the flow direction is scattered, the liquid is in a turbulent flow state, water drop dissection time of the liquid is increased, and rectification separation effect of the liquid is greatly improved.

Description

technical field [0001] The invention relates to packing used in industrial tower equipment, in particular to a streamlined ceramic valley-peak regular corrugated packing used in industrial distillation and separation towers of chemical industry and petrochemical industry. Background technique [0002] At present, there are many kinds of fillers used in drying towers, washing towers and rectification separation towers in chemical, petrochemical and other industries, and the fillers used in rectification separation towers are mostly made of several pieces of corrugated ceramics for separation. The corrugated packing formed by the staggered stacking of plate monomers. When the liquid is separated by rectification, one is that the packing strength of the ceramic corrugated plates is not high enough. When they are stacked together, the corrugated flow channels on the contact surface of the packing are straight and vertically staggered, so the flow direction of the liquid betwee...
