Water-oxygen fractionating purification vacuum glove box

Abstract

The invention relates to a water-oxygen fractionating purification vacuum glove box which is characterized in that an air pump (21) is taken as a power source, air in a system is circularly purified by flowing through a water purifying chamber and an oxygen purifying chamber, the water purifying chamber is divided into a front stage and a rear stage, and the fractionating purification of water in the air is realized, thereby the aim for purifying water and oxygen with high efficiency is achieved. A separation net four group is formed by a stainless steel filter sieve (26), an external upper ring (27), an external lower ring (28), an internal upper ring (37) and an internal lower ring (38), and the purification chamber is divided into two water purifying chambers and one oxygen purifying chamber.

Description

Technical field [0001] The invention relates to a vacuum work station which requires purification of water and oxygen, especially a vacuum glove box whose operating environment requires high purification of water and oxygen. Background technique [0002] At present, the known vacuum glove box purifies water and oxygen together, and mainly relies on adsorption to purify water and oxygen in the gas. This integrated purification has the following disadvantages: First, the water and oxygen adsorbents will interact with each other in the process of adsorbing water and oxygen, thereby affecting the water and oxygen purification effects. To overcome this effect, the amount of water and oxygen adsorbents must be increased, resulting in The cost increases and raw materials are wasted; the second is that the water adsorbent uses a reagent, which cannot absorb and purify water to a greater extent, resulting in unsatisfactory water purification effects; the third is that the reduction a...
