Tshwj xeeb Nitrogen Generator Rau Kev Siv Nitrogen Ua Tshuab Hauv Mining Zoo

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

Thaum cov huab cua nyob rau hauv lub pressurized los ntawm purification thiab ziab, Base on Aerodynamics, nitrogen thiab oxygen nyob rau hauv cov huab cua nyob rau hauv lub zeolite molecular sieve (ZMS) ntawm lub siab viav vias adsorption yuav ua tau zoo ntawm txawv diffusion tus nqi los ntawm adsorption ntawm nitrogen. Oxygen nyob rau hauv carbon molecular sieve nyob rau saum npoo ntawm diffusion tus nqi yog siab tshaj nitrogen. Thaum lub adsorption tsis nyob rau hauv qhov sib npaug, oxygen tau nqus los ntawm carbon molecular sieve nyob rau hauv ntau qhov ntau, thiab nitrogen tau concentrated thiab enriched nyob rau hauv lub roj theem kom tiav kev sib cais ntawm oxygen thiab nitrogen.
