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.
