Novel structured corrugated packing without wall flow

Abstract

The invention discloses novel structured corrugated packing without wall flow. The novel structured corrugated packing comprises first-layer corrugated packing nets, a third-layer corrugated packing net, a middle fixing hoop ring and a flow guide plate. The first-layer corrugated packing nets are connected with second-layer corrugated packing nets by first fixing hoop rings, the third-layer corrugated packing net is connected with the corresponding second-layer corrugated packing net by a second fixing hoop ring, a first pattern drainage wall is fixed to the outer side of the third-layer corrugated packing net, the middle fixing hoop ring is positioned between the third-layer corrugated packing net and a fourth-layer corrugated packing net, and the flow guide plate is positioned on the inner side of the middle fixing hoop ring. The novel structured corrugated packing without the wall flow has the advantages that mass transfer can be uniformly carried out on liquid, the liquid on inner walls can be preliminarily blocked and can be prevented from downwardly flowing from the inner walls, liquid which is permeated into the inner walls can be guided and can flow onto the flow guide plate, the liquid on the inner walls can be guided to the inner sides of the packing nets, uniform mass transfer can be carried out again, accordingly, wall flow effects can be effectively prevented, and the separation efficiency of the packing can be improved.

Description

technical field [0001] The invention relates to the technical field of structured materials, in particular to a novel wall-free structured corrugated packing. Background technique [0002] In chemical engineering, most of the structured packings used are corrugated packings, which are disc-shaped packings composed of many corrugated sheets, and when the liquid flows down the packing layer, it tends to gradually concentrate on the tower wall, making The liquid flow near the tower wall gradually increases, this phenomenon is called wall flow. The wall flow effect causes the gas-liquid two-phase distribution in the packing layer to be uneven, thereby reducing the mass transfer efficiency. The wall flow rate of ordinary structured packing is at least 30%, and most of them are above 40%. Therefore, the loss rate of packing separation efficiency 15-24%. In view of the above problems, it is urgent to design a new type of wall-free structured corrugated packing. Contents of the ...
