Background technology
In chemical process, usually can carry out processed to material, dewatering has: distillation, rectifying, infiltrate membrane technology etc.When resins synthesis, sometimes need to do strict control to the water content in solvent, must processed be taked.Distillation and rectifying need to consume a large amount of heat energy; Infiltrate membrane technology equipment investment is large, and technical requirement is high.
Utility model content
The purpose of this utility model is: for the problem that in the dehydration of above-mentioned organic solvent, existence is consumed energy, cost is high, provide a kind of dehydrating tower of organic solvent, utilize molecular sieve filling to dewater, and device structure is simple, and cost is low, simple to operate, consumes energy low.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of dehydrating tower of organic solvent, comprise tower body, tower body top is provided with drain, material outlet and vacuum interface, be provided with feed(raw material)inlet and discharging hole bottom tower body, tower body surface is wrapped up in and is provided with heating jacket, and heating jacket top is connected with heating agent outlet, heating jacket bottom is connected with heating agent entrance, fill molecular sieve filling in tower body, in tower body, bottom is provided with the band hole column plate of supported molecular-sieve filler, band hole column plate is provided with the plate hole that some apertures are less than molecular sieve filling diameter; Described tower body is also provided with at least one for picking and placeing the hand hole of molecular sieve filling.
Preferably, described tower body height is 1000mm, and internal diameter is 300mm, and tower body thickness is 5mm.
Preferably, the outer wall of described heating jacket is provided with fixing otic placode.
Preferably, described hand hole is provided with two, is arranged in tower body upper and lower.
Preferably, described hand hole internal diameter is 150mm.
Owing to have employed technique scheme, the beneficial effects of the utility model are:
The dehydrating tower of a kind of organic solvent of the present utility model, by vacuumizing process to tower body, under vacuum conditions by adding heating agent in heating jacket, to the molecular sieve filling regeneration activating in tower body, and then close vacuum interface, moisture organic solvent, by molecular sieve filling, reaches the object of dehydration; This dehydrating tower structure is simple, and cost is low, and dewatering efficiency is high, is particularly useful for the dehydration of resinae organic solvent.
