Specialized Nitrogen Generator For Application Of Nitrogen Making Machine In Mining Well

The main use of nitrogen in the mining industry is to prevent fires or explosions. The essence of nitrogen injection for fire prevention and extinguishing is to inject a certain flow of nitrogen into the oxidation zone or fire area of the goaf, reducing its oxygen content to below 7% or 3%, achieving the purpose of fire prevention and extinguishing. It can effectively eliminate the danger of gas explosion, prevent natural heating and spontaneous combustion of coal, and reduce combustion intensity

When the air in the pressurized through the purification and drying, Base on Aerodynamics, nitrogen and oxygen in the air in the zeolite molecular sieve (ZMS) on the Pressure swing adsorption  will performance of different diffusion rate through the adsorption of nitrogen. Oxygen in carbon molecular sieve on the surface of the diffusion rate is higher than nitrogen. When the adsorption was not in balance, oxygen was absorbed by carbon molecular sieve in large quantity, and nitrogen was concentrated and enriched in the gas phase to achieve separation of oxygen and nitrogen.
