A multifunctional glove box purification device

Abstract

The invention relates to a multifunctional glovebox purification device which comprises a column body, wherein a first cavity, a second cavity and a third cavity which are communicated are sequentially formed in the column body in a working gas inlet direction, wherein the first cavity is filled with an organic solvent adsorbing material, the second cavity is filled with a deoxidizing material, the third cavity is filled with a dewatering material, a working gas inlet and a vacuumizing port are formed in the first cavity, and a working gas outlet is formed in the third cavity. According to the device, the working gas enters from the inlet, passes through the first cavity, the second cavity and the third cavity sequentially and is discharged from the working gas outlet; gas is purified, the effects of organic solvent adsorbing, deoxidizing and dewatering are achieved in the three cavities sequentially, and compared with the prior art, the problems that two column bodies are required to be used for removing an organic solvent, oxygen and water respectively, the pipeline is complicated and space is occupied due to the fact that three filling materials influence and interfere each other during regeneration are solved; and multiple purification functions and regeneration are achieved in the same column body, the structure is simple, the leakage rate is reduced, the space utilization rate is high, and the working efficiency is increased simultaneously.

Description

technical field [0001] The invention belongs to the field of glove boxes, in particular to a multifunctional glove box purification device. Background technique [0002] The glove box is a laboratory equipment that fills the box with high-purity inert gas and circulates and filters out the moisture and oxygen in it. The glove box can provide a water-free and oxygen-free closed inert gas atmosphere, which can not only prevent the deterioration of water and oxygen-sensitive substances, but also prevent harmful substances from being exposed to the air. The glove box includes a main box and a transition compartment. In order to minimize the oxygen and moisture content in the main box of the glove box, a purification column is required to pass the external working gas through the purification column first and then into the box. When the glove box is working, the gas in the box needs to be purified. The column circulates. [0003] In the traditional technology, the purification...

AI Technical Summary

Problems solved by technology

In order to absorb organic solvents, traditional glove boxes generally use additional purification columns, and when the adsorption material is saturated, the adsorption material needs to be replaced, which not only increases the cost, but also easily causes the glove box to leak, and reduces work efficiency.
