Product Description
After the raw air is compressed by the air compressor, it enters the high-pressure air tank, and then goes through a filter to remove impurities and enters the adsorption tower of the PSA oxygen generator. After nitrogen and oxygen separation, pure nitrogen enters the high-pressure nitrogen tank, and then enters the refrigerating circulating nitrogen liquefier to be liquefied. The liquid nitrogen is restricted to atmospheric pressure and then enters Dewar for storage.

In the refrigerating stage, the mixed working substance is throttled by the single-stage compressor, condenser and regenerative heat exchanger to provide the cooling capacity for the cooling cycle. After passing through the compressor and condenser, the refrigerant is cooled by the throttling refrigerating stage of the mixed working medium in the regenerative heat exchanger. After throttling, the refrigerant enters the nitrogen liquefier to provide cold capacity for nitrogen liquefaction supplied by the pressure swing adsorption nitrogen production unit. Mixed working medium precooling machine is based on regenerative throttling refrigeration cycle, the refrigeration temperature from ambient temperature to the target, optimization of multiple components including the boiling point of pure quality, and the mixed working medium, the effective cooling temperature area covered with overlap each other, to improve the refrigeration temperature matching area distribution, and realize effective refrigeration temperature regions boiling point groups each yuan relay matching, thus making a big temperature across the efficient refrigeration, can obtain higher under relatively small pressure difference of throttling refrigeration effect. Therefore, it is possible to adopt a closed cycle throttling refrigerator driven by a single stage compressor.

Liquid nitrogen is a liquid with a low temperature of - 196 ºC and is obtained from nitrogen which occupies more than 70% of the air. Inert, colorless, non-toxic, volatile, very wide range of use. Liquid nitrogen is easy to volatilize at low temperature, so it is generally stored in a special container liquid nitrogen tank.
According to the use of liquid nitrogen purity classification, often divided into food grade liquid nitrogen, industrial grade liquid nitrogen. The purity of food grade liquid nitrogen is high, because considering the safety of human consumption, the purity reaches 5 9, that is 99.999%. The purity of industrial grade liquid nitrogen is not as high as that of food grade liquid nitrogen.
In the process of using liquid nitrogen, people often think that the safety is not good, but because of the low temperature of liquid nitrogen, it will gasify immediately when it meets air, so the safety is still guaranteed. Just pay a little attention to safety, and there should be safety awareness in any case. Performance requirements
