This kind of oxygen genrator is equipped with blower, vacuum pump, switching valve, the adsorber and oxygen tank.
Air through pressurization then filling into roots blower filled with oxygen molecular sieve adsorber,moisture, carbon dioxide, nitrogen adsorption to produce oxygen.
When adsorption to a certain extent,vacuum pump could make great use of air, vacuum adsorption of moisture, carbon dioxide, nitrogen, and small amounts of other gases were pulled out side by side to the atmosphere, adsorbent regeneration.
The above process steps through PLC and switching valve system to realize automatic control.

Application field and compared with the method of cryogenic
The effect of open hearth oxygen is combustion.Its purpose is to strengthen smelting process, shortening time of smelting and improving open hearth furnace steel production.Practice has proved that open hearth oxygen can make double amount of steel-production, fuel consumption can reduce 33%-50%.
Electric furnace with oxygen can ferment burden of melting and oxidation of impurities which means that the electric furnace oxygen could improve production capacity and improve the quality of special. Smelting electric furnace oxygen consumption of per ton steel differs from the steel grade, for example, oxygen consumption for smelting carbon structural steel per ton is 20-25m3, but oxygen consumption of high alloy steel is 25-30m3. The required oxygen concentration for 90%-94% oxygen enrichment.
Oxygen-enriched air blast furnace can significantly reduce coking, increase production. according to the statistics, increasing 1% oxygen concentration, and its iron production can improve 4%-6%, coking reduce 5%-6%.
In the process of smelting non-ferrous metal, sulfur can be fully burnt, smelting temperature, improve the smelting speed. Take copper for example, copper smelting with enriched air can be energy-saving 50%, under the same burnup, the production of copper can be doubled.
