VPSA oxygen system is mainly composed of blower, vacuum pump, switching valve, adsorber and oxygen balance tank, etc. Raw air is pressurised by Roots blower into the adsorber filled with oxygen molecular sieve.in which water, carbon dioxide and nitrogen are adsorbed to produce oxygen. When adsorbed to a certain extent, the vacuum pump is used to evacuate it, and the adsorbed water, carbon dioxide, nitrogen and a small amount of other gas components are pumped out and discharged into the air, and the adsorbent is regenerated. The above process steps are automatically controlled by PLC and switching valve system.
The role of VPsA (Vacuum Pressure swing Adsorption) oxygen blowing in open-hearth furnaces is to assist in combustion
Its purpose is to enhance the smelting process, shorten the smelting time, and increase the steel production capacity othe open-hearth furnace. Practice has proven that oxygen blowing in open-hearth furnaces can increase steel production by more than double and reduce fuel consumption by 33% to 50%. The use of oxygen in electric furnaces can accelerate the melting of furnace charge and the oxidation of impurities, which means that oxvgen blowing in electric furnaces can both increase production capacity and improve the quality of specialized products. The oxygen consumption per ton osteel in electric furnaces varies depending on the type of steel being smelted, with carbon structural steel requiring 20-25cubic meters of oxygen per ton and high-alloy steel requiring 25-30 cubic meters. The required oxygen concentration forthis process is enriched oxygen at 90% to 94%. Enriched oxygen blasting in blast furnaces can significantly reduce cokingand increase production. According to statistics, an increase in oxygen concentration by 1% can lead to a 4% to 6% increase in iron production, a 5% to 696 reduction in coking, and especially when the coal injection rate for coal-based iron making reaches 300 kg per ton of iron, the corresponding oxygen requirement is 300 cubic meters per ton of iron.Introducing oxygen into the smelting process of non-ferrous metals allows sulfur to burn completely, maintaining the smelting temperature and increasing the melting speed. Taking copper as an example,
enriched oxygen copper smelting
can save 50% of energy, which means that copper production can be doubled with the same fuel consumption.
