Control panel
After being compressed and filtered by the compressor, the air enters the polymer membrane filter. Due to the different solubility and diffusion coefficients of various gases in the membrane, the relative permeation rate of different gases in the membrane is different. Based on this characteristic, various gases can be divided into "fast gas" and "slow gas".
Under the pressure difference between the two sides of the membrane, gases with relatively fast permeation rates, such as water, hydrogen, argon, hydrogen sulfide, carbon dioxide, etc., penetrate the membrane and are enriched on the permeation side of the membrane, while gases with relatively slow permeation rates, such as methane, nitrogen, carbon monoxide, and argon, are retained on the side of the membrane and enriched, thus achieving the purpose of gas mixture separation

1. What qualities does liquid nitrogen have?
Nitrogen gas is referred to as liquid nitrogen. As is well known, the majority of the atmosphere is composed of nitrogen (78.03% by volume and 75.5% by weight). Nitrogen has a boiling point of -196.56 oC under normal pressure and can expand to a volume of 696 cubic meters of pure gaseous nitrogen (21 oC) from 1 cubic meter of liquid nitrogen. Liquid nitrogen may be produced at higher temperatures if it is compressed. Due to excessive heat absorption during vaporization, liquid nitrogen, as an inert, colorless, odorless, non-corrosive, non-flammable substance with an extremely low boiling point, can result in frostbite.
2. What functions does liquid nitrogen serve?
Liquid nitrogen is being used more and more frequently these days, which is really convenient for us. When liquid nitrogen was first employed, it was primarily for freezing treatments in industrial production. However, these days, liquid nitrogen is being used for freezing and cooling in a growing number of fields.Liquid nitrogen has a chemical reaction with deep refrigerants in industrial production. It can be used for biological tissues and instantly freeze them without endangering biological activity because of its chemical inertness.Rapid freezing can be used in surgery to help halt bleeding and remove superficial skin surface areas that need to be removed, as well as in medicine to preserve living tissues and store biological samples.
3, Safety precautions for liquid nitrogen
(1) Liquid nitrogen is an extremely cold liquid(-196 ºC)that, if splashed on skin, can result in frostbite similar to burns. Consequently, extra care should be taken when adding and taking away liquid nitrogen;
(2) Do not use sealed plugs in place of the designated tank cover to prevent damage to the container from the continuous evaporation of liquid nitrogen and the resulting increase in nitrogen pressure;
(3) A useful plastic or solid wooden rod should be inserted into the bottom of the container to measure the height of the liquid level inside, and it should be removed after 5 to 10 seconds. The height of the liquid level determines the length of frost formation;
(4)Windows should be left open in spaces where liquid nitrogen is kept for an extended period of time for ventilation.
