PSA Nitrogen Generator Process
Technology of PSA Nitrogen Generator
After the air is compressed to 0.85MPa by the compressor and cooled to about 40℃ by the compressor rear cooler, it enters the air purification unit to remove the dust, water and oil mist in the compressed air, and then enters the PSA transformer adsorption unit. The unit is equipped with two adsorption towers, one tower adsorption nitrogen production, one tower deattachment regeneration, through the PLC control switch valve switch, so that the two towers cycle alternately. The four working processes of adsorption, homogenization, desorption and purging are as follows.
1-air compressor; 2-filter; 3-dryer; 4-filter; 5-PSA adsorption tower; 6-filter; 7-nitrogen buffer tank
1. Adsorption
When the clean compressed air enters the A tower and flows to the outlet through the molecular sieve, the pressure of Tower A gradually rises to about 0.8MPa. The O2, CO2 and H2O in the air are adsorbed by the molecular sieve, and the unadsorbed nitrogen flows out from the adsorption tower outlet into the nitrogen buffer tank, and the adsorption duration is about 60s.
2. Equal pressure
After the molecular sieve in tower A is saturated, the adsorption is stopped, and it carries out a brief equalization process for tower B: the inlet and outlet valves of the two towers are closed, the equalization valve is opened, and the gas is pressed to the tower through the equalization valve of the adsorption tower through the equalization valve, so that the pressure of the two towers reaches balance, and the duration is about 2s. The average pressure can reduce the impact of the backward blowing gas on the molecular sieve and improve the air recovery rate.
3. Dissolution
After the equalization is completed, tower A continues to exhaust through the outlet, quickly reducing the pressure of the adsorption tower to the atmospheric pressure, so as to remove the adsorbed O2, CO2 and H2O, and realize the desorption and regeneration of the molecular sieve.
4. Blow
In order to regenerate the molecular sieve, A piece of product nitrogen is used to sweep A tower upstream. Parsing and purge duration for a total of 60s. While one tower is absorbing and producing nitrogen, the other tower is undergoing regeneration (desorption and purging) process, and tower A and Tower B alternately perform adsorption, pressure equalization and regeneration to complete the separation of oxygen and nitrogen and continuously output nitrogen.
