cryogenic nitrogen generation Technical principle: The Cryogenic Nitrogen Plant uses the method of deep freezing air separation, that is, liquefying the air and then separating them using the different boiling points of oxygen and nitrogen. That is, it is a method of separating air by the nature of the difference in the concentration of gas and liquid. 聽 Technical advantages锛?/span 2-1 Adopt high-performance centrifugal air compressor. 2-2 Pre-cooling system: (1) The air-conditioning unit assembled with imported compressors has low power consumption, flexible cooling capacity adjustment and reliable performance. (2) The system can cool the air to 7掳C, effectively preventing the occurrence of water-carrying accidents in the molecular sieve adsorber. 2-3 Purification system: (1) Select molecular sieve dedicated for air separation, make the CO2 content in the air after the adsorber 1PPm (2) The molecular sieve adsorber can be switched in 8 hours, with few regeneration times and low power consumption. (3) The switching valve of the purification system is made of Japanese tooling products, with reliable action, zero leakage, and switching times greater than 100,000. 2-4Fractionator system: (1) Adopt single-stage distillation and exhaust gas expansion cycle. (2) The heat exchange system composed of the main heat exchanger, liquefier and subcooler distributes the cooling capacity reasonably, effectively reducing the loss of liquefaction before air rectification and vaporization after liquid air throttling and insufficient reheating. (3) Use high-efficiency convection rectification tower. (4) The full-immersion condensing evaporator adopts explosion-proof design, which further enhances the safety and stability of equipment operation. (5) There is no separate heating system. The heating, cooling, liquid accumulation and purification of the fractionating tower are all done in one go. The operation is simple and fast, and the start-up time is less than 20 hours. (6) Set up a liquid nitrogen backflow system to shorten the start-up. 2-5Turbine expansion unit: (1) The expansion impeller adopts NREC software design, five-coordinate CNC machining, gas bearing, fan brake, high isentropic efficiency and reliable operation. (2) Considering the stability and reliability, the fan brake is adopted. 2-6 Liquid nitrogen storage and vaporization system: The self-pressurization of the storage tank is used to replace the liquid nitrogen pump, which reduces investment and is reliable in operation. 聽 Ancillary equipment: 聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽 Centrifugal Air Compressor1 set Air pre-cooling system1 set Purification system1 set Booster Turboexpander1 set Fractionation Column System1 set Nitrogen Compression System1 set liquid storage system1 set Instrument control system1 set Electronic control system1 set 聽 Main equipment configuration: 聽 Who we are?
