Liquid phase redistributor for spray towers

Abstract

The invention relates to a liquid phase redistributor for spray towers. The liquid phase redistributor comprises a distribution plate 3 and a support 4 for supporting the distribution plate 3, wherein the distribution plate 3 is annular, and is annularly arranged along the tower wall 1 of a spray tower; the tower wall 1 is provided with a reinforcing plate 2; an annular outer ring of the distribution plate 3 is welded on the tower wall 1 through the reinforcing plate 2; an annular inner ring of the distribution plate 3 is inclined two the lower part of the tower wall 1; and the lower part of the distribution plate 3 is provided with the support 4 which is fixedly connected with the reinforcing plate 2. The liquid phase redistributor can improve the distribution condition that sprayed slurry is dense in the middle and thin at the periphery in the tower, improves the gas absorption efficiency near the tower wall, improves the slurry utilization rate, reduces operating cost of equipment such as a circulating pump, has the advantages of simple manufacturing process, no blockage and entrainment, convenience of installation and simple operation and maintenance, and can be widely applied to various spray towers.

Description

technical field [0001] The invention relates to an internal component of a spray tower, in particular to a liquid phase redistributor of the spray tower. Background technique [0002] The spray tower can be widely used in the absorption and treatment of various gases in the production process of chemical industry, electronics, metallurgy, electroplating, textile (chemical fiber), food, machinery manufacturing and other industries. The spray tower is mainly composed of multi-stage spray layers, demisters, circulation pools and other components. The gas is introduced into the spray tower through the flue or air duct, passes through the spray layer, and contacts with the spray absorption liquid in reverse, undergoes absorption and neutralization reactions, and then is dehydrated and defogged by the demister and then discharged from the flue or air duct at the outlet of the tower . The absorption liquid is sent to the spray layer by the circulating pump in the circulating pool...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a liquid phase redistributor to improve the absorption efficiency of the spray tower in order to solve the problem of uneven distribution of the spray slurry in the middle of the spray tower and the phenomenon of wall slippage that occurs during the spraying process. and equipment investment and operating costs
