Corrugated plate structured packing with embedded-type end surfaces and manufacturing method thereof

Abstract

The invention provides a corrugated plate structured packing with embedded-type end surfaces and a manufacturing method thereof. The corrugated plate structured packing is implemented in such a way that the packing is a disc-like packing formed mainly by putting packing sheets together, the end surfaces of the packing sheets adopt mutually embedded structures, the flow paths of individual sheets adopt non-through structures and are drained mutually, and the middle area of each packing sheet reserves the structural form of a conventional corrugated plate packing and forms a gas and liquid passage capable of enabling gas and liquid to be in contact to transfer heat and mass in the main body of the packing. The manufacturing method comprises the following steps: stainless steel, aluminum or copper is adopted to fabricate a metal material belt; the metal material belt is cut to form the packing sheets; the packing sheets pass through an upper die and a lower die which are used for cutting during cutting, so that the end surfaces of two packing sheets in the front and at the back of the dies respectively are cut and bent to obtain corrugated plate structured packing sheets with embedded-type end surfaces finally; and in the subsequent packaging process, the end surface structures of two adjacent packing sheets are mutually embedded and then form a disc finally. The corrugated plate structured packing with embedded-type end surfaces has the characteristics that the design is reasonable, the structure is simple, the processing is easy, wall flow effect can be reduced and even eliminated during the use effectively, gas-liquid distribution is further improved, and the heat and mass transfer of the packing is improved.

Description

technical field [0001] The invention relates to a metal material, which can be used in heat transfer and mass transfer equipment such as rectification towers, absorption towers, extraction towers, stripping towers, and water washing towers in petrochemical, fine chemical, and gas separation industries. Plate corrugated structured packing in which the end faces of adjacent packing sheets are embedded in each other in the packing disc. Background technique [0002] Since the 1980s, structured packing has gradually emerged due to its advantages of large flux, low resistance, high efficiency, and convenient installation, and has been widely used in petroleum, chemical, cryogenic, light industry and other industrial fields. So far, structured packing has won a considerable market share in the column internals equipment business, and its market share is still expanding. [0003] Plate corrugated structured packing is a product with relatively good performance among many structure...

AI Technical Summary

Problems solved by technology

[0004] Because there is a certain angle between the corrugation of the packing sheet and the axis of the tower, the liquid at the end of the packing sheet accumulates along the flow channel to the edge, resulting in a wall flow effect. The accumulation also further causes the gas to rise rapidly from the central area of ​​the tower body, and the packing fails to provide an effective contact interface for the gas-liquid mass transfer, resulting in a decrease in the heat transfer and mass transfer efficiency of the packing, which directly affects the normal operation of the structured packing tower
