Problems solved by technology
The advantage is that it can achieve any ultra-low temperature condensation, but the disadvantage is that it can only provide a stable temperature
[0007] Although the gas fractional condensation method mentioned above has a certain condensation effect on the gas, the classification effect is extremely poor. Therefore, after many gas components are condensed, they need to be further fractionated and separated by other chemical methods.

Abstract
The invention relates to a gas condensation and grading device and an application method thereof. The gas condensation and grading device comprises ultra-low temperature gas serving as a cold source, collection pipes arranged in parallel, a heat preservation layer, a cold source transmission pipe, pipe valves, heat transmission clamping plates and a temperature detector, wherein the cold source is connected with the cold source transmission pipe; the collection pipes are connected with one another through the pipe valves; the collection pipes and a thermocouple probe of the temperature detector are together arranged between the heat transmission clamping plates in parallel; and the heat preservation layer wraps the cold source transmission pipe and the heat transmission clamping plates. The gas condensation and grading device is simple in structure and convenient to operate; the ultra-low temperature gas can be made just by controlling flowing speed of liquid nitrogen, liquid oxygen, liquid helium or a mixed solution; the heat transmission clamping plates, the cold source transmission pipe and the collection pipes are made of simple materials and can be manufactured easily; and a temperature gradient can be formed by changing the arrangement density of transmission condensation pipes.
Description
【Technical field】 [0001] The invention relates to a gas condensing device, in particular to a gas classification device and an application method. 【Background technique】 [0002] Gas is a form of existence of matter, and many gases are produced in daily life and industrial production. The air contains particulate matter, moisture, carbon monoxide, nitrogen oxides, etc. Chemical production exhaust gases contain many volatile and semi-volatile components, some of which can cause harm to the human body. Therefore, the treatment of gases has always been subject to the international community Much attention. Many products in industrial production are volatile and semi-volatile substances. It has become the main direction of gas research to extract the required beneficial components or remove harmful substances from them through fractional condensation of gases. [0003] There are mainly the following kinds of gas fractional condensation methods commonly used today: [0004] (1...
