Applications of Pressure Swing Adsorption Air Separation Equipment

　　Pressure Swing Adsorption Air Separation EquipmentThis is a technical product that uses the principle of "PSA" pressure swing adsorption air separation equipment to separate air. Compressed air purified by an air purification dryer enters the bottom of the adsorption tower, which is filled with zeolite molecular sieves that have a strong adsorption capacity for nitrogen under certain pressure. When air passes through the zeolite molecular sieve adsorption bed, nitrogen is adsorbed, and oxygen is concentrated at the top of the tower. After odor removal, dust removal, and sterilization filters, qualified medical oxygen is obtained. The entire adsorption process is free of chemical reactions and environmental pollution. So, let's learn about the application fields of pressure swing adsorption air separation equipment!

　　Metallurgy: The copper refining process includes the process of smelting copper ore into blister copper and the process of blister copper refining. It is different from the electrorefining process of electrolytic copper. Copper ore contains a large amount of sulfur impurities. The reaction between sulfur and oxygen usually occurs around 600℃, generally after blowing in hot air and heavy oil combustion. However, if oxygen enrichment can be achieved at this time, the purpose of increasing heavy oil production and saving can be achieved. The purification method is the traditional ISP method, which can simultaneously purify zinc and aluminum. Lead-zinc ore and aluminum ore are desulfurized and sintered under the action of a flux (limestone). The sintered block is at 900~650℃, and smelting is carried out through the combined action of hot air and coke. Increasing the oxygen content of the transported hot air can reduce the amount of heavy oil used, achieving the purpose of increasing production while improving efficiency.

　　Pressure Swing Adsorption Air Separation Equipment in Foundry: When manufacturing castings, air is delivered into the top-blown furnace or electric furnace, so that the oxygen in the air reacts with the coal molecules in the furnace, and the heat generated by melting the matrix metal (a mixture of pig iron or crushed iron, etc.) is used to form the casting mold. If the oxygen concentration in the air used in the foundry is increased by 2%, the combustion efficiency will be improved. In particular, the casting process must be around 1500℃, but the initial low-temperature fluid must be tempered before heating. The use of oxygen enrichment can reduce the amount of re-smelting in this part and improve production efficiency. Small and medium-sized furnaces mostly use liquid oxygen for oxygen enrichment, but large enterprises have already used 500m3/h PSA equipment.

　　Pressure Swing Adsorption Air Separation Equipment in Cement Production: Cement raw materials are made by calcining quicklime in limestone in a calcination furnace at around 900℃. Using oxygen enrichment during heating can save fuel and increase production. Now, there are enterprises using PSA equipment everywhere. Without PSA equipment, people cannot identify enterprises using PSA equipment everywhere. Without this PSA equipment, people would not be able to recognize the impact of PSA equipment on oil Price. Regarding other various roasting furnaces, because whether it is possible to achieve oxygen enrichment and increased production using PSA equipment has not been fully studied, it has not yet been popularized in these fields.

　　Plasma Cutting: In the welding and cutting fields, high-oxygen gas is used internally, and high-purity gas is basically used to prevent nitriding. However, the purity of oxygen used for oxygen plasma cutting can be around 93%. Therefore, users of plasma cutting machines are interested in adding small PSA equipment to the system.
