Process description of small liquid nitrogen generator

 

The air compressor provides compressed air and enters the air purification system. The air purification system consists of a freeze dryer, three-stages filter, and a high-efficiency degreasing purifier. After the air purification system removes water, removes dust, and removes oil, it is clean. The compressed air enters the pressure swing adsorption(PSA) nitrogen generator to obtain nitrogen of acceptable purity. Nitrogen enters the nitrogen liquefier. The nitrogen liquefier consists of a precooling refrigerator and a mixed-refrigerant J-T regrigerator. The mixed-refrigerant J-T regrigerator is a mixed working medium composed of various refrigerants, which can reach a low temperature of -196℃. Nitrogen is fully exchanged with the heat exchanger of the main compressor to become liquid nitrogen, flows out from the nitrogen liquefier outlet valve, and enters the liquid nitrogen storage tank for use.
