Description

TECHNICAL FIELD

This invention relates to a decontaminating column used in the field of glove boxes, in particular to a decontaminating column for on-line replacing adsorption material and a glove box.

BACKGROUND TECHNOLOGY

A glove box is widely used in medicine, biology, chemistry and chemical engineering, nuclear energy, lithium electricity, mechanical processing and other high-tech research fields, as well as production and manufacturing processes.

Currently, in the decontaminating column of the glove box equipment, its internal purification materials should be replaced timely after the adsorption and saturation, otherwise, it will influence the purification performance of decontaminating column. At present, there are three usual replacement modes:

I. Utilize regeneration methods to directly conduct regeneration and recovery for the purification materials in decontaminating column, but this method will spend a long time, occupy the normal operating time and influence scientific research and production efficiency;II. Prepare two or more decontaminating columns in glove boxes and achieve one-use and one backup or one-use and multiple backup, to improve the work efficiency of replacing decontaminating column. But the decontaminating column is the core part of the glove box and it has a large share, so the manufacturing cost of the glove box is higher;III. If the manufacturers directly replace the whole decontaminating column, they will dismantle the glove box with a higher maintenance cost, and it will influence the atmosphere purity in the glove box. The atmosphere replacement is needed in the later period, which also influences the work efficiency of the glove box.Invention Contents
