1.   Compressed air purification system The compressed air provided by the AC
air compressor usually contains oil and water, which will reduce the adsorption capacity of carbon molecular sieve, so the compressed air must be removed before entering the nitrogen and oxygen separation system. First, the air is compressed to 0.75-0.9MPa by an air compressor and enters the air purification device, and most of the water, oil and impurities are removed by the pipeline filter, and then the water is removed by the refrigerated dryer to make the pressure dew point reach 2 ℃ -10 ℃ , again After the fine filter, the super fine filter, and the activated carbon degreasing device, clean compressed air with a pressure of 0.75-0.9MPa , a pressure dew point of 2 ℃ -10 ℃ , and an oil content of ≤0.01PPm is obtained.
Compressed air purification system AC is composed of freeze dryer, fine filter, super fine filter, activated carbon degreasing device, automatic drain valve, ball valve, etc.

2.   Air storage tank system The role of the CG
air storage tank system is to ensure a stable air supply source, prevent the instantaneous air flow velocity from being too fast when the nitrogen and oxygen separation system is switched, affect the air purification effect, and improve the quality of the compressed air entering the adsorber, which is beneficial Extend the life of molecular sieve.
The air storage tank system CG is composed of an air storage tank, a safety valve, a stop valve, and a pressure gauge.

3.   Nitrogen-oxygen separation system NGN
oxygen-nitrogen separation system is the core part of air separation. Its main body is two adsorption towers filled with carbon molecular sieves. When clean compressed air enters an adsorption tower, O2 , CO2 and trace H2O are removed by carbon molecular sieve. Adsorption, nitrogen is output from the outlet end. When one tower is adsorbing nitrogen, the other tower removes the O2 , CO2 and H2O adsorbed in the molecular sieve from the micropores by decompressing, so as to realize the regeneration and desorption of the molecular sieve. The two towers alternately perform adsorption and regeneration, and continuously output nitrogen.
The oxygen-nitrogen separation system consists of an adsorption tower, carbon molecular sieve, pneumatic valve, muffler, throttle valve, compression cylinder, pressure gauge, etc. packed in the tower.

4.   Nitrogen buffer system The main function of the NT
nitrogen buffer system is to balance the pressure and purity of the nitrogen separated from the nitrogen-oxygen separation system to ensure continuous supply of nitrogen. At the same time, when the adsorption tower is regenerated to the adsorption switch, it will backfill part of the qualified nitrogen stored in the adsorption tower protection bed, and also help the adsorption tower to increase the pressure.
The nitrogen buffer system consists of a buffer tank, a flow meter, a dust filter, a pressure regulating valve, a throttle valve, and a safety valve.

High efficiency:
Ruibang's unique molecular sieve filling technology and perfect overall design, when the nitrogen concentration and gas production are the same, the power consumption is the least, and the operating cost is the lowest.

Good recovery:
using the best performance carbon molecular sieve, combined with a unique gas distribution technology and specific process flow process, the carbon molecular sieve to maximize energy efficiency, the best recovery of nitrogen.

Long service life of the whole machine:
With many years of experience and advanced technology, Ruibang has designed a complete compressed air purification system, so that the activated carbon in the activated carbon oiler is always in a compressed state, absolutely not pulverized, and twice in the adsorption tower The purification protection system and the unique molecular sieve compression mechanism that uses nitrogen to compress the molecular sieve, and an alarm ( sound and light ) system is set up . When the alarm is issued, the molecular sieve should be stopped immediately to add the molecular sieve. Ensure that the molecular sieve will not be poisoned and powdered due to oil .

High reliability:
It can not only implement automatic switching, automatic adjustment of flow and purity, to achieve true unmanned operation, but also has a series of alarm devices such as low flow and low purity. Pressing cylinder device is spacious Secretary own research development, and with a secondary alarm system.

All-round service:        
From selecting and designing the nitrogen generation system according to user requirements to installation, debugging and permanent tracking service and technical support, it can ensure that users receive all-round services safely and reliably.
