Working principle

After being compressed by an air compressor, the raw air enters the air storage tank after dust removal, oil removal and drying, and then enters the A adsorption tower through the A intake valve. At this time, the tower pressure rises, the nitrogen molecules in the compressed air are adsorbed by the zeolite molecular sieve, and the unadsorbed oxygen passes through the adsorption bed and enters the oxygen buffer tank through the outlet valve. This process is called adsorption. After the adsorption process is over, the adsorption tower A and the adsorption tower B are connected through a pressure equalizing valve to balance the pressure of the two towers. This process is called equalizing pressure. After the pressure equalization is over, the compressed air passes through the B intake valve and enters the B adsorption tower, and the above adsorption process is repeated. At the same time, the oxygen adsorbed by the molecular sieve in the adsorption tower A is decompressed and released into the atmosphere through the exhaust valve A. This process is called desorption, and the saturated molecular sieve is adsorbed and regenerated. Similarly, the right tower is also desorbed when tower A is adsorbing. After the adsorption of Tower B is completed, it will also enter the pressure equalization process, and then switch to the adsorption of Tower A, so that the cycle alternates and continuously produces oxygen. The above-mentioned basic process steps are all automatically controlled by PLC and automatic switching valve.

Technical characteristics 
1. Equipped with air pretreatment equipment such as refrigeration dryer, which effectively guarantees the service life of molecular sieve.
2. Using high-quality pneumatic valve, short opening and closing time, no leakage, service life of more than 3 million times, meeting the requirements of frequent use of pressure swing adsorption process, and high reliability.
3. Using PLC control, it can realize fully automatic operation, convenient maintenance, stable performance and low failure rate.
4. The gas production and purity can be adjusted within an appropriate range.
5. Continuously optimized process design, combined with the selection of new molecular sieves, minimizes energy consumption and capital investment.
6. The device is assembled in a complete set to reduce on-site installation time and ensure quick and easy on-site installation.
7. Compact structure design, less floor space.

Oxygen generator process

oxygen generator is a device that uses advanced PSA pressure swing adsorption technology, uses clean compressed air as raw materail, and zeolite molecular sieve as adsorbent, to extract high-purity oxygen at room temperature, the equipment has the advantages of stable operation, convenient operation and maintance, high purity of output oxygen, and low input cost. professional products can be customized according to the specific needs of users.

oxygen generators can us widely used in different filed such as medical bresthing, industrial cutting, agriculture and fishery, the products of this series possess the certificates of CE and ISO9001, ISO13485.
