A DEVICE FOR OXYGEN SEPARATION FROM ATMOSPHERIC AIR
The atmosphere determines the processes that take place on the Earth. The atmosphere is primarily made up of nitrogen and oxygen but it also includes smaller amounts of inert gases, carbon dioxide, aqueous vapor, dust and some contaminants. The content of oxygen, nitrogen and inert gases in the atmosphere is the same everywhere. The gas composition is 78.2% nitrogen, 20.9% oxygen and 0.9% inert gases by volume. The concentration of carbon dioxide, aqueous vapor and dust depends on local conditions. Commercial production of oxygen, nitrogen and inert gases is based on air liquefaction and its separation into constituent gases using their different boiling points. This method is highly-productive and the products of separation are very pure, but its main disadvantage is high energy consumption. There are many methods of atmospheric air separation into its primary components. The research goal was the development of a device to separate oxygen from air to be used in air conditioners, ventilation systems for oxygen enrichment of indoor air, and in internal combustion engines to improve fuel mixture characteristics. We have proposed a utility model of “A device for oxygen separation from atmospheric air” (Patent No. 166798). The developed device may be used in air conditioners, ventilation systems for oxygen enrichment of indoor air, and in internal combustion engines to improve fuel mixture characteristics. The oxygen separation device contains housing with air intake port and oxygen and nitrogen outlet ports, electromagnet, cooler and compressor. The body is divided by a partition into gas intake and separation chambers; the cooler is located in the separation chamber and is connected to the compressor; its outlet duct is made in the form of elbow and mounted above the inner cavity of the annular electromagnet. The electromagnet is located on the oxygen outlet port, while the nitrogen outlet port is located in the side wall of the separation chamber at bottom level; the oxygen outlet port is located in the bottom of this chamber.
