A gas distribution device for two-way diversion in rectification equipment

Abstract

The invention discloses a gas distribution device for two-way diversion of distillation equipment. The gas distribution device mainly comprises a connection plate, side plates, upper guide plates and lower guide plates, wherein the two side plates are arranged on the left and right; one end of each of the two side plates is connected with the connection plate and is welded and fixed with a tower wall of distillation equipment through the connection plate; the other end of each of the two side plates is fixedly connected with a support structure on the tower wall through bolts; a non-closed gas channel is formed by surrounding of the connection plate, the side plates and the tower wall of the distillation equipment; and a plurality of upper guide plates and lower guide plates are arranged in the gas channel and are symmetrically arranged on the left and right relative to the section of the tower center, so that the gas forms two air streams which flow upwards and downwards respectively after entering a distributor, thus achieving two-way diversion; therefore, the gas distribution device is capable of distributing the gas relatively evenly and reducing the resistance of the distributor, and has the advantages of being simple in structure, economical, reasonable, safe, stable, excellent in performance and the like.

Description

technical field [0001] The invention relates to a gas distribution device with two-way diversion, especially a gas phase feed distribution device widely used in rectification equipment such as air separation and chemical industry, belonging to the technical field of gas distribution in energy air separation and chemical equipment . Background technique [0002] With the rapid development of my country's industry, the demand for oxygen, argon and nitrogen in iron and steel smelting, petrochemical, coal chemical, large chemical fertilizer and other enterprises has increased sharply, which has driven the development of rectification towers towards large and extra large ones. The uniform distribution in the column is the main problem of column expansion. At the same time, with the continuous advancement of packing technology, the development of new high-efficiency packing with large void ratio and low pressure drop has higher and higher requirements for the initial gas distribut...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a gas distribution device for two-way flow diversion in rectification equipment. In order to achieve the purpose of uniform distribution of the gas feed in the tower; at the same time, by using a part of the kinetic energy of the intake air, the effect of reducing the resistance loss of the distributor is achieved; in addition, this distribution device can also make full use of the gap between the inlet pipe and the liquid surface. The distance between them increases the gas diffusion space and makes the gas distribution more uniform
