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.
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. The glove box not only provides the anhydrous and anaerobic experimental environment for various scientific research and production, but also offers safety protection to the science researchers, such as, medical biology, anti-bacteria and disease prevention, nuclear energy radiation protection and leakage prevention, as well as poisonous gas prevention of chemistry and chemical engineering, etc.
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.
To solve the above technical problems, this invention provides a decontaminating column for on-line replacing adsorption material and a glove box, which can solve the problems of low efficiency, high manufacturing cost and high maintenance cost generated by three modes in the existing technology;
To achieve the above purpose, the technical proposal of this invention is as follows:
Decontaminating column for on-line replacing adsorption material; it includes:
a tank having an inner tank being used for filling the adsorption material and one end of the tank being set to be opened;
at least one discharging part being attached to the tank, and an open-close unit by which the adsorption material can be discharged and which is installed between the discharging part and the tank;
a chamber in the discharging part, which is connected to a gas replacement unit.
The decontaminating column for on-line replacing adsorption material provided by this invention is mainly comprising the tank for filling adsorption material and the discharging part attached to the tank. There is an open-close cover on the tank and an open-close unit between the discharging part and the tank for discharging the adsorption material. Meanwhile, a chamber is set in the discharging part, which communicates with the gas replacement unit. When the adsorption material in the tank is saturated or cannot reach the capability requirements, the empty material bottle is connected to the butt joint opening of the discharging part. After the completion of butting, gas replacement of the material bottles is conducted through gas replacement unit and chamber, and the replaced gas shall be consistent with the gas atmosphere in the chamber. Then, the open-close unit is opened to discharge the used adsorption material, and the open-close unit is closed after the discharging process. Next, a cover on the tank is opened, the activation adsorption material in the material bottle is directly poured into the tank, and it can be used again after covering. The replacement operation of decontaminating column is completed.
Therefore, compared with the existing technology, this invention effectively solves the problems of low efficiency, high manufacturing cost and high maintenance cost generated by decontaminating column replacement mode in the existing technology. In addition, when the decontaminating column is used in the glove box, replacing the adsorption material can ensure that the water oxygen in the glove box is prevented from being leaked out.
On the basis of the above technical proposal, this invention can also make the following improvements:
