Membrane N2 Generator for Laser Cutting

Working principle of gas supply scheme for membrane nitrogen generator The laser cutting auxiliary gas supply scheme of the membrane nitrogen generator mainly uses membrane separation nitrogen production technology to separate oxygen and nitrogen in the air. Using compressed air as the gas source, the solubility and diffusion rate of oxygen and nitrogen in the air are different under the pressure difference on both sides of the membrane. Oxygen molecules with smaller diameters (O2) have a faster diffusion rate, while oxygen molecules with faster permeation rate first pass through the membrane as exhaust gas, while nitrogen (N2) with slower permeation rate stays in the gas phase for enrichment. In this way, oxygen and nitrogen are separated to obtain the gas phase enrichment product nitrogen, which is used as product gas output.
