According to the invention, a seat of a low-temperature rectification system suitable for laboratory research operation is formed by arranging all the components, wherein the structure is simple, the process is reasonable, the operation difficulty is low, the energy consumption is low, and the purity and the efficiency of separation and purification are guaranteed.

Description

technical field [0001] The invention relates to the technical field of separation and purification, in particular to a laboratory biochemical gas separation and purification device. Background technique [0002] When the laboratory conducts research in the field of biochemical industry, it is often necessary to separate and purify biochemical gases with complex components. There are a variety of existing gas separation and purification methods, including condensation and distillation, absorption, adsorption and membrane separation, etc., which help people to choose according to the specific composition of gas components. One of the methods of separation and purification is called cryogenic rectification. [0003] Cryogenic rectification, as the name implies, is rectification at a temperature lower than the boiling point of a certain gas. The difference between cryogenic rectification and distillation is that it has two refluxes, a liquid phase reflux and a gas phase reflux...
