Plate ripple arranged packing having optical margin structure and manufacturing method thereof

Abstract

A plate ripple arranged packing having optical margin structure and manufacturing method thereof is disclosed. The plate ripple arranged packing is mainly formed by scraping packing sheets together to form a disc-like packing; the packing contact area of two adjacent discs is provided with an optical margin area; the other regions on the packing sheets constituting the packing of each disc are roughly-processed surface and gas, liquid channels capable of making gas and liquid contact to transfer heat and mass are formed in a packing main body. The method includes: adopting a stainless steel or aluminium-made metal material belt to produce the packing sheet; during the surface roughing process of the packing sheet, keeping an optical surface structure for the surface having certainly-sized width left in two side edges and the surface roughing process being not performed; performing surface roughing process on the packing sheet in the middle region so as to form a main body surface having excellent hydromechanical and mass transfer performance; then performing large ripple pressing so as to form the plate ripple arranged packing having optical margin structure. The invention is rationally structured, simply structured, easy to process, capable of effectively improving the gas liquid distribution in the use process; it is able to reduce the resistance of contact point between discs and improve the heat and mass transfer effect of the packing.

Description

technical field [0001] The invention relates to a kind of heat transfer and mass transfer equipment made of metal materials, which can be used in refining towers, absorption towers, extraction towers, stripping towers, water washing towers, etc. Improved plate corrugated structured packing in . Background technique [0002] Plate corrugated structured packing has the advantages of large flux, small resistance, high efficiency, and strong anti-pollution ability, and is widely used in petroleum, chemical, cryogenic, light industry and other industries. Plate corrugated structured packing originated in the 1930s. With the widespread application of Meile Parker packing of Sulzer Company in Switzerland, the structured packing technology has made great progress, and the processing technology of plate corrugated structured packing has also changed from the initial simple large grain Forming has developed into a variety of processing techniques including punching, surface roughenin...

AI Technical Summary

Problems solved by technology

[0003] In order to increase the gas-liquid contact area, almost all the plate corrugated structured packings currently used in the industry adopt surface roughening methods such as embossing or embossing to enhance the mass transfer process on the surface of the packing sheet, but at the same time this also causes The contact resistance of gas and liquid on the packing surface increases, especially in the structured packing tower, the pressure drop in the contact area between two adjacent packing plates increases sharply, which easily leads to liquid flooding. Back-mixing creates conditions that lead to a decrease in the heat transfer and mass transfer efficiency of the packing, which directly affects the normal operation of the structured packing tower.
