Liquid Nitrogen system - Large liquid nitrogen machine product features

The large liquid nitrogen machine is a complete set of equipment for liquefaction and separation of air into oxygen, nitrogen and other rare gases such as argon, krypton, xenon, neon and helium by deep freezing.

 

The working principle of

The principle of deep freezing method is based on the different boiling points of each component of a gas mixture, which is separated by partial condensation or liquefaction distillation process at low temperature. In the deep freezing method, chemical method, electrolysis method, adsorption method, membrane osmosis method and other oxygen and nitrogen production methods, the deep freezing method is the most economical, the best adaptability, the most widely used.

 

Technical principle of liquid nitrogen machine

The liquid nitrogen machine is a cryogenic mixed working medium throttling refrigerator driven by a single compressor with precooling to achieve nitrogen liquefaction (-180ºC). Cryogenic mixed working medium throttling refrigerator is based on the regenerative type of multiple mixed working medium throttling refrigeration cycle. From the ambient temperature to the target refrigeration temperature, the highest, middle and low boiling point pure components constitute multiple mixed working medium, and realize the relay matching of the effective cooling temperature zone of each boiling point element. It is a kind of refrigerator that can be used to realize the temperature zone of -40ºC~-196ºC. The advantages of this product are: it can use mature commercial compressors, heat exchangers and other equipment in the market; High liquefaction efficiency, high reliability, no maintenance, long service life.

The principle of liquid nitrogen machine equipment is based on the principle of pressure swing adsorption, using high-quality carbon molecular sieve as adsorbent, under a certain pressure, nitrogen from the air. After purifying and drying compressed air, the adsorption and desorption are carried out under pressure and pressure in the adsorber. Due to the kinetic effect, the diffusion rate of oxygen in the micropores of carbon molecular sieve is much higher than that of nitrogen. When the adsorption is not in equilibrium, nitrogen is enriched in the gas phase to form the finished nitrogen. Then the pressure is reduced to normal pressure, and the adsorbent desorbs the adsorbed oxygen and other impurities to achieve regeneration. Generally set up two adsorption tower in the system, one tower adsorption nitrogen production, the other tower desorption regeneration, through PLC program automatic control, so that the two tower alternating cycle work, oxygen and nitrogen adsorption separation, so as to get qualified nitrogen.

Application industry

Liquid nitrogen drip.

Liquid nitrogen infusion is widely used in beverage, edible oil and pharmaceutical production.

Liquid nitrogen infusion can be divided into completely sterile infusion and conventional infusion. Aseptic infusion of liquid nitrogen through the heat exchanger to cool sterile nitrogen, so as to achieve aseptic infusion. Conventional infusions are made of sterile nitrogen directly liquefied into liquid nitrogen, which is then injected into drinks or cooking oils.

Now, many beverage manufacturers have accepted nitrogen or nitrogen and C02 confounds instead of the traditional C02, to hold inflatable packaging drinks. High-carbonated drinks filled with nitrogen caused fewer problems than drinks filled with carbon dioxide alone; Nitrogen is used in canned still beverages, such as wine and fruit juices. The advantage of adding liquid nitrogen to non-aerated beverage cans is that the small amount of liquid nitrogen injected will remove oxygen from the top space of each can, leaving the gas in the upper space of the tank inert and thus extending the storage life of perishables.
