Stainless steel nitrogen generator components and workflow:

1. Compressed air purification component

The compressed air provided by the air compressor is first introduced into the compressed air purification assembly. The compressed air first removes most of the oil, water and dust from the pipeline filter, and then further removes water through the freeze dryer, and removes oil and dust from the fine filter. Deep purification is carried out by a superfine filter that follows. According to the system conditions, Jinpai specially designed a compressed air degreaser to prevent possible oil infiltration and provide sufficient protection for the carbon molecular sieve. The rigorous design of the air purification unit ensures the life of the carbon molecular sieve. The clean air treated by this module can be used for instrument air.


2, air storage tank

The function of the air storage tank is to reduce the pulsation of the airflow and to act as a buffer; thereby reducing the pressure fluctuation of the system, so that the compressed air smoothly passes through the compressed air purification component, so as to sufficiently remove the oil and water impurities and reduce the load of the subsequent PSA oxygen and nitrogen separation device. At the same time, when the adsorption tower is working to switch, it also provides a large amount of compressed air required for rapid pressure rise in a short time for the PSA oxygen-nitrogen separation device, so that the pressure in the adsorption tower quickly rises to the working pressure, ensuring reliable and stable equipment. run.


3. Oxygen and nitrogen separation device

There are two adsorption towers with special molecular sieves, A and B. When clean compressed air enters the inlet end of the A column and flows through the carbon molecular sieve to the outlet end, O2, CO2 and H2O are adsorbed by it, and the product nitrogen flows out from the outlet end of the adsorption tower. After a period of time, the carbon molecular sieve in the A column is adsorbed and saturated. At this time, the A tower automatically stops the adsorption, and the compressed air flows into the B tower for oxygen absorption and nitrogen production, and the A tower molecular sieve is regenerated. The regeneration of the molecular sieve is achieved by rapidly dropping the adsorption tower to atmospheric pressure to remove the adsorbed O2, CO2 and H2O. The two towers alternately perform adsorption and regeneration, complete oxygen-nitrogen separation, and continuously output nitrogen. The above processes are all controlled by a programmable logic controller (PLC). When the nitrogen purity level of the outlet end is set, the PLC program acts, the automatic venting valve is opened, and the unqualified nitrogen is automatically vented to ensure that the unqualified nitrogen does not flow to the gas point.


4, nitrogen buffer tank

A nitrogen buffer tank is used to equalize the pressure and purity of the nitrogen separated from the nitrogen-oxygen separation system to ensure continuous supply of nitrogen. At the same time, after the adsorption tower is switched, it will recharge some of its own gas to the adsorption tower. On the one hand, it helps the adsorption tower to boost, and also plays the role of protecting the bed. It plays an extremely important process in the process of equipment operation. Supporting role.
