VPSA（Vacuum Pressure Swing Adsorption）is a non-cryogenic gas separation technology that uses special solids (adsorbents) as molecular sieves to segregate the Nitrogen and Oxygen from the mixture of air. Roots Blower and Vacuum Pump are the main equipment for the VPSA system.
Vacuum Pressure Swing Adsorption (VPSA) is an advanced gas separation technology that utilizes the different selectivity of adsorbents for gas molecules to separate gas components. Based on the principle of VPSA technology, the VPSA-O2 units adopt the special adsorbent (model: PU-8) to enrich the oxygen in the air and supply it to the user.
Firstly to remove mechanical impurities with filter. After desorption, a Roots Blower blows The VPSA-O2 into the adsorption vessel of the VPSA-O2 system. The adsorber is a double-vessel system, and its product is oxygen. It will absorb Nitrogen, carbon dioxide, and water vapor in the air. After saturated adsorption, a vacuum pump will work to desorb the adsorbents in the adsorption vessel completely for regeneration. The double-vessel VPSA-O2 system ensures continuous oxygen generation through the cyclic switch of the program control valve under the control of PLC (data control system).
1. The energy consumption is relatively low. The greater the oxygen production, the lower the energy consumption.
2. The maintenance cost is low. The moving equipment is a Roots blower and Roots vacuum pump. Because their working principles are both positive displacement, oil-free. Therefore，they are easy to maintain.
3. The whole set of equipment has a high degree of automation. The moving equipment and the oxygen generator are controlled synchronously. Just press the start button and the whole set of equipment can operate normally.
4. Suitable for medium and large output.
In conclusion. the above is a simple introduction to the VPSA system. Shandong Mingtian Machinery Group is specialized in manufacturing roots blowers and roots vacuum pumps since 2007. We have provided Roots blowers and Roots vacuum pumps for well-known domestic VPSA companies and have accumulated lots of experience. In this case, If you encounter any problems with the roots blower or roots vacuum pump for your VPSA system, we are glad to be able to help you.
