Automatic equal volume distribution device for cluster distillation reflux liquid

Abstract

The invention discloses an automatic equivalent distributing device of cluster distillation reflux. The automatic equivalent distributing device of the cluster distillation reflux comprises an external groove wall, an inner reflux groove connected with a reflux discharge pipe, and a plurality of reflux flowing guide pipes; the external groove wall is positioned on the outer periphery of the inner reflux groove; a plurality of baffles which are distributed radially by taking the center of the inner reflux groove as a circle center is connected between the external groove wall and a wall plate of the inner reflux groove; reflux sub-grooves are formed between adjacent baffles; moreover, reflux flowing hole groups with the same arrangement are respectively formed in the wall plate of the inner reflux groove and corresponding parts of the corresponding reflux sub-grooves; additionally, the flow liquid hole groups are communicated with the inner sides of the corresponding reflux sub-grooves; the reflux flowing guide pipes are communicated with the bottoms of the outer side of the corresponding reflux inner groove. According to the device, the reflux is automatically and equivalently distributed to a plurality of distillation towers, so that the distillation effect is improved.

Description

technical field [0001] The invention relates to an automatic equivalent distribution device for cluster rectification reflux liquid, belonging to the technical field of rectification. Background technique [0002] At present, cluster distillation consists of N (N>1) high-efficiency small-diameter distillation towers, replacing the traditional single-column process of series-connected low-efficiency large-caliber distillation towers. In the industrial tower reactor from 200L to 500L, N towers are used An independent glass rectification tower with its own glass condenser at the head of the tower, N automatic and multiple linkage distributors, and finally N discharge pipes are collected to the outer wall of the discharge tank, and then connected to the receiving storage tanks of each component to complete The whole operation process of cluster distillation. [0003] Although the rectification device of the 500L tower kettle can no longer be regarded as laboratory equipment,...

AI Technical Summary

Problems solved by technology

[0003] Although the rectification unit of the 500L tower kettle can no longer be regarded as laboratory equipment, on the scale of industrial production, glass equipment can no longer be used if cluster distillation is to be applied to a larger unit, and only one overhead condenser can be used. In this way, the equal distribution of the reflux liquid becomes the key device for the application of cluster rectification in large rectification units

[0004] The traditional cluster distillation reflux liquid distributor, for the cluster distillation distribution test, can not meet the requirement of equal distribution of N tower tubes
