1.  Compressed Air Purification SystemAC
The compressed air provided by the air compressor usually contains oil and water, which will reduce the adsorption capacity of the carbon molecular sieve. Therefore, the oil and water must be removed before the compressed air enters the nitrogen-oxygen separation system. First, the air compressor compresses the air to0.75-0.9MPaEnter the air purification device, remove most of the water, oil, and impurities by the pipeline filter, and then dehydrate with a refrigeration dryer to achieve a pressure dew point of2℃-10℃After that, it passes through a fine filter, an ultra-fine filter, and an activated carbon oil remover to obtain a pressure of0.75-0.9MPaand a pressure dew point of2℃-10℃and an oil content of≤0.01PPmof clean compressed air.
Compressed Air Purification SystemACIt consists of a refrigeration dryer, fine filter, ultra-fine filter, activated carbon oil remover, automatic drain valve, ball valve, etc.

2.  Air Storage Tank SystemCG
The role of the air storage tank system is to ensure a stable air supply and prevent excessively fast instantaneous airflow during the switching of the nitrogen-oxygen separation system, thereby affecting the air purification effect and improving the quality of the compressed air entering the adsorption tower, which helps to prolong the lifespan of the molecular sieve.
Air Storage Tank SystemCGIt consists of an air storage tank, safety valve, shut-off valve, pressure gauge, etc.

3.  Nitrogen-Oxygen Separation SystemNGN
The oxygen-nitrogen separation system is the core part of the air separation process. Its main components are two adsorption towers filled with carbon molecular sieves. When clean compressed air enters one adsorption tower,O2、CO2and trace amounts ofH2Oare adsorbed by the carbon molecular sieve, and nitrogen is output from the outlet. When one tower is adsorbing nitrogen, the other tower is depressurized to allow theO2、CO2andH2Oto be discharged from the micropores, achieving regeneration and desorption of the molecular sieve. The two towers alternately perform adsorption and regeneration, continuously outputting nitrogen.
The oxygen-nitrogen separation system consists of adsorption towers, carbon molecular sieves filling the towers, pneumatic valves, silencers, throttling valves, clamping cylinders, pressure gauges, etc.

4.  Nitrogen Buffer SystemNT
The main function of the nitrogen buffer system is to balance the pressure and purity of the nitrogen separated from the nitrogen-oxygen separation system and ensure a continuous supply of nitrogen. At the same time, when the adsorption tower switches from regeneration to adsorption, it will refill the adsorption tower bed with some qualified stored nitrogen, and it also helps to increase the pressure of the adsorption tower.
The nitrogen buffer system consists of a buffer tank, flowmeter, dust filter, pressure regulating valve, throttling valve, safety valve, etc.
1. Compressed Air Purification System AC

Compressed air provided by air compressors usually contains oil and water, which reduce the adsorption capacity of carbon molecular sieves. Therefore, oil and water must be removed from the compressed air before it enters the nitrogen-oxygen separation system. First, the air compressor compresses the air to 0.75-0.9MPa and sends it to the air purification device. A pipeline filter removes most of the water, oil, and impurities. Then, a refrigeration dryer removes water to achieve a pressure dew point of 2℃-10℃. After passing through a precision filter, an ultra-precision filter, and an activated carbon oil remover, clean compressed air with a pressure of 0.75-0.9MPa, a pressure dew point of 2℃-10℃, and an oil content ≤0.01PPm is obtained.

2. Air Storage Tank System CG

The role of the air storage tank system is to ensure a stable air supply and prevent excessively high instantaneous airflow rates during nitrogen-oxygen separation system switching, which would affect the air purification effect. It improves the quality of compressed air entering the adsorber and helps extend the life of the molecular sieve.

The air storage tank system CG consists of an air storage tank, safety valve, shut-off valve, pressure gauge, etc.

3. Nitrogen-Oxygen Separation System NGN

The oxygen-nitrogen separation system is the core part of the air separation process. Its main components are two adsorption towers filled with carbon molecular sieves. When clean compressed air enters one adsorption tower, O2, CO2, and trace amounts of H2O are adsorbed by the carbon molecular sieve, and nitrogen gas is output from the outlet. When one tower is adsorbing nitrogen, the other tower is depressurized to release the O2, CO2, and H2O adsorbed in the molecular sieve from the micropores, achieving regeneration and desorption of the molecular sieve. The two towers alternately perform adsorption and regeneration to continuously output nitrogen.

The oxygen-nitrogen separation system consists of adsorption towers, carbon molecular sieves packed in the towers, pneumatic valves, silencers, throttle valves, clamping cylinders, pressure gauges, etc.

4. Nitrogen Buffer System NT

The main function of the nitrogen buffer system is to balance the pressure and purity of the nitrogen separated from the nitrogen-oxygen separation system and ensure a continuous supply of nitrogen. At the same time, when the adsorption tower switches from regeneration to adsorption, it refills the adsorption tower bed with some qualified stored nitrogen, which also helps to increase the pressure of the adsorption tower.

The nitrogen buffer system consists of a buffer tank, flow meter, dust filter, pressure regulating valve, throttle valve, safety valve, etc.
High Efficiency:

Ruibang's unique molecular sieve filling technology and perfect overall design achieve the lowest power consumption and operating cost for the same nitrogen concentration and gas production.

High Recovery Rate:

Using the currently best-performing carbon molecular sieve, combined with unique gas distribution technology and specific process flow, maximizes the energy efficiency of the carbon molecular sieve and achieves optimal nitrogen recovery.

Long Machine Life:

Ruibang's years of experience and advanced technology have designed a complete compressed air purification system, ensuring the activated carbon in the activated carbon oil purifier is always in a compressed state, absolutely preventing pulverization. A secondary purification protection system within the adsorption tower and a unique molecular sieve compression mechanism using nitrogen to compress the molecular sieve are also incorporated, along with an alarm (audio-visual) system. In case of an alarm, immediately stop the machine and add molecular sieve. This ensures that the molecular sieve will not be poisoned by oil or pulverized.

High Reliability:

It not only allows for automatic switching, flow, and purity automatic adjustment, achieving truly unattended operation, but also has a series of alarm devices such as low flow and low purity. The compression cylinder device is independently developed by our company and has a secondary alarm system.

Comprehensive Service:

From selecting and designing a nitrogen generation system according to user requirements to installation, commissioning, and permanent follow-up service and technical support, we ensure that users receive comprehensive and reliable service.
