Industrial production process, toxic and hazardous, flammable, volatile materials need inert gas protection, and Nitrogen Gas Generator as an inert gas, rich in air, the air content of 79%, in the production of the application has become increasingly widespread. Nitrogen plant is currently widely used in safety protection gas, replacement gas, nitrogen injection three times, coal mine fire extinguishing, nitrogen-based atmosphere heat treatment, anti-corrosion explosion, the electronics industry, integrated circuits.
In the field of nitrogen production more use of carbon molecular sieves and zeolite molecular sieves. Molecular Sieve separation of oxygen and nitrogen is mainly based on the diffusion rate of these two gases on the surface of molecular sieve. Carbon molecular sieve is a kind of carbon-based adsorbent that combines the characteristics of activated carbon and molecular sieve. Carbon molecular sieve has a very small pore composition. Smaller diameter gas diffusion faster, more into the molecular sieve solid phase, so that you can get the gas in the nitrogen enrichment components. Molecular sieve nitrogen is air as raw material, carbon molecular sieve as adsorbent, the use of pressure swing adsorption principle, the use of carbon molecular sieve selective adsorption of oxygen and nitrogen and oxygen separation method, commonly known as PSA nitrogen plant.
Due to the difference of adsorption amount, adsorption speed, adsorption force and the adsorption capacity of different adsorbents on adsorbents, PSA PSA unit can complete the adsorption and separation of mixed gas under pressure Process to reduce the pressure desorption of adsorbed impurity components, in order to achieve gas separation and adsorbent recycling. In some emerging materials industries, applications of inert gases such as electronics, integrated circuits, beer and beverage are also continually expanding into new applications. Such as the new PSA nitrogen gas generator device has been used for lithium-ion cell phone production of inert protection, nitrogen for beer and other packaging, dehydration of nitrogen gas generator in the production of silicon drying, snack foods instead of air and deoxidizer for nitrogen packaging. The application of nitrogen gas generator makes the products of these enterprises in the process technology, product quality, won the competition.
