What is the working principle of the nitrogen machine in the nitrogen machine series?

Nitrogen producing machine -----



Under normal temperature and pressure, the difference of adsorption amount of oxygen and nitrogen in the air on the surface of carbon molecular sieve and the difference of diffusion rate of oxygen and nitrogen in carbon molecular sieve are used to control the opening and closing of the pneumatic valve through a programmable controller to realize the process of pressurized adsorption and decompression desorption, complete the separation of oxygen and nitrogen, and obtain the required purity nitrogen. The purity and gas production of nitrogen can be adjusted according to customer requirements. The purity of nitrogen can reach 95%--99.99995%, and the gas production is 1Nm3 /h--3000Nm3 /h.

The adsorption tower equipped with special carbon molecular sieve has A and B two. When the clean compressed air enters the inlet end of tower A and flows through the carbon molecular sieve to the outlet end, O2, CO2 and H2O are adsorbed by it, and the product nitrogen flows out from the outlet end of the adsorption tower. After A period of time, the carbon molecular sieve in Tower A is saturated by adsorption. At this time, tower A automatically stops adsorption, compressed air flows into Tower B for oxygen absorption and nitrogen production, and the molecular sieve of Tower A is regenerated. The regeneration of molecular sieve is achieved by rapidly dropping the adsorption tower to atmospheric pressure to remove the adsorbed O2, CO2 and H2O. The two towers are alternately adsorbed and regenerated to complete the separation of oxygen and nitrogen and the continuous output of nitrogen. The above processes are controlled by a programmable logic controller (PLC). When the purity of nitrogen at the outlet is greater than the set value, the PLC program functions, the automatic vent valve is opened, and the unqualified nitrogen is automatically emptied to ensure that the unqualified nitrogen does not flow to the gas point.
