Purification column and inert gas equipment

Abstract

The invention provides a purification column. The purification column comprises a shell, the interior of the shell comprises at least one purification unit, the purification unit can be filled with different types of purification materials, or the purification unit comprises a plurality of purification sub-units filled with the purification materials. The purification column provided by the invention realizes a plurality of adsorption functions, the functions are equivalent to those of a plurality of columns connected in series or in parallel, the purification column is flexible and changeableto meet multiple complex process requirements of current users, even the users can freely choose the purification column according to needs, and the safety and economy are better.

Description

technical field [0001] The invention relates to the field of gas purification, in particular to a purification column and inert gas equipment. Background technique [0002] Inert gas equipment is widely used in high-tech research fields and manufacturing processes such as medicine, biology, chemical engineering, nuclear energy, lithium batteries, and machining. Inert gas equipment can not only provide a water-free and oxygen-free experimental environment for various scientific research and production, but also provide safety protection for scientific research workers, such as medical biological anti-bacteria and disease prevention, nuclear energy radiation protection and leakage prevention, and chemical and chemical engineering Anti-toxic gas and so on. [0003] At present, the inert gas equipment mainly includes a box body, a gas purification column, a circulation unit, and a control unit. The principle is that the control unit controls the opening of the circulation unit...

Problems solved by technology

[0004] At present, the inert gas equipment is getting bigger and bigger, and the required purification column functions are more and more, and the removal of impurities is becoming more and more complicated. figure 1 As shown, the upper end of the purification column is the air inlet, the lower end is the air outlet, and the inside of the column is a packing layer. The thicker the packing layer, the more layers, the more inconvenient to replace materials and maintain; during the purification process, close to the inlet The purification material at the tuyere absorbs more and more impurities, and the purification ability is seriously weakened, while the utilization rate of the purification material near the air outlet is low, the utilization of the purification material in the purification column is unbalanced, and the integral purification column is not convenient for local replacement of purification materials, resulting in In addition to the serious waste of purification materials, it increases the cost of use
