Summary: Pressure swing adsorption (PSA) oxygen generators utilize the differing adsorption capacities of gases on adsorbents at various pressures to separate the components of air, a non-cryogenic air separation technique. Since the primary components of air are nitrogen and oxygen, adsorbents with differing adsorption selectivities for nitrogen and oxygen can be selected, and an appropriate process designed to separate nitrogen and oxygen, producing oxygen.

       Pressure Swing Adsorption Oxygen GeneratorThis is a non-cryogenic air separation technology that utilizes the different adsorption capacities of gases on adsorbents under different pressures to separate various gases in the air. Because the main components of air are nitrogen and oxygen, adsorbents with different adsorption selectivity for nitrogen and oxygen can be selected, and an appropriate process can be designed to separate nitrogen and oxygen to produce oxygen.

  Pressure swing adsorption separates oxygen and nitrogen through pressure changes, where the mixed gas is adsorbed onto the adsorbent, and oxygen is obtained at the desired concentration during the desorption cycle. Therefore, the nitrogen adsorption capacity and nitrogen-oxygen separation coefficient of the molecular sieve are important factors determining the scale and technical and economic indicators of the PSA deoxygenation device.

        Molecular sieves have good wear resistance and a long service life, which can significantly reduce oxygen energy consumption and equipment operating costs, and improve economic efficiency.

       Pressure Swing Adsorption Oxygen GeneratorAccording to the PSA pressure swing adsorption principle, using air as the raw material and fluorite molecular sieve as the adsorbent, it utilizes the different diffusion rates of oxygen and nitrogen molecules in the molecular sieve pores to achieve air separation.

      Characteristics of Pressure Swing Adsorption Oxygen Generators

   1. The secondary raw material of the pressure swing adsorption oxygen generator is air; no complete auxiliary materials are needed. It uses the principle of pressure swing adsorption (PSA). In short, the PSA principle is the abbreviation of the pressure swing adsorption principle in English; it is a purely natural and purely physical oxygen method.

   2. The raw material required for this oxygen generation is the air outside. The oxygen produced has the advantages of high concentration, no pollution, cleaning, being environmentally friendly, safe, low operating cost, and few alternative methods. It represents the development direction of the oxygen generation field and the future of healthy oxygen health care. Even PSA oxygen generation is an advanced oxygen generation method.

   3. Powerful; after power-on, the oxygen supply and flow rate can be directly adjusted to achieve excellent results.

    Pressure Swing Adsorption Oxygen GeneratorOperating costs

   1. The pressure swing adsorption oxygen generator belongs to the field of gas preparation equipment technology. In short, using a pressure swing adsorption oxygen generator and this oxygen generator is related to ozone preparation equipment.

   2. The pressure swing adsorption oxygen generator is mainly composed of a blower, a vacuum pump, switches, valves, and adsorption tanks (such as oxygen balance tanks).

   3. The adsorption tank has an end located at the end and inlet and outlet ports, but the inlet and outlet ports are generally located at the front and rear positions in the area.

   4. In particular, the adsorption tank is filled with molecular sieves, activated alumina, and adsorbents to form an adsorption layer in my opinion.

   5. After the raw material air removes dust particles through a filter, it is pressurized and adsorbed by a blower.

   6. In general, after most of these adsorption tanks are adsorbed, in short, the adsorbent will immediately reach a high level.
