( Blue font to view hyperlink)
Our company specialize in making various kinds of gas generators and gas compressors, such as:Diaphragm compressor,Piston compressor, Air compressors,Nitrogen generator,Oxygen generator ,Gas cylinder,etc. All products can be customized according to your parameters and other requirements.
Nitrogen generators with cylinder filling produce gaseous Nitrogen from compressed air on-site and offer a cost-effective, reliable and safe alternative to traditional Nitrogen gas supplies such as cylinders or cryogenic liquid. Nitrogen generators with cylinder filling are available in standard models with capacity ranging from 0.27m3/hr to 60m3/hr at 99.9999% purity with cylinder filling pressures up to 200 Bars. The design is made for round the clock 24/7 operation. Each generator is
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.
