Product Description on N2 generator equipment:

Process flow

System 1. Compressed air system

First, the raw air is compressed by an 18.5KW screw compressor with an outlet pressure of 0.8MPa and a gas production volume of 3.0m3/min, and then enters the compressed air purification system.

System 2. Low dew point purification system (skid-mounted integrated)

The compressed air first enters the gas-liquid separator to remove most of the liquid oil, water, and dust, and then enters the refrigerated dryer, which reduces the normal pressure dew point of the compressed air to about -40°C and removes a large amount of gas and liquid moisture. , and then filtered by three precision filters to ensure that the oil content is ≤ 0.001ppm and the dust content is ≤ 0.01μm. Finally, the clean compressed air enters the back-end PSA nitrogen generation system.

System 3. Nitrogen production system (skid-mounted integrated)

The clean compressed air is buffered by the air buffer tank and then enters two pressure swing adsorption separation towers filled with adsorbents (high-performance carbon molecular sieve and dehydrated molecular sieve, composite bed structure), that is, the nitrogen generator . The compressed air enters from the bottom of the adsorption tower. After the air flow is diffused through a special multi-stage stainless steel air diffuser, it enters the adsorption tower evenly for adsorption and separation of oxygen and nitrogen. Then oxygen flows out from the outlet end. This process is through pressure equalization and pressure reduction (to normal pressure) to remove the adsorbed impurity components (mainly O2 and CO2) in the adsorbent to complete the regeneration of the adsorbent. The two adsorption towers operate in alternating cycles, continuously feeding raw air, and continuously producing nitrogen.

The nitrogen from the nitrogen generator enters the CG-0.3/0.84 nitrogen buffer tank and the XSF-1 fine dust filter, and then passes through a GWY-20/6-31 nitrogen booster to obtain a purity of 99.999% and a yield of 25m³/h purity nitrogen, output pressure 3.1MPa, normal pressure dew point ≤ -40℃, oil content ≤ 0.001ppm, dust content ≤ 0.1μm.

The nitrogen generator is equipped with a nitrogen analyzer, thermal flow meter, venting device, and pressure regulating device. All equipment starts and stops with one click, touch screen display, online analysis, and remote communication (optional, 485 or Ethernet interface can be provided).

 Technical advantages of nitrogen production equipment
1. Carbon molecular sieve

High-quality carbon molecular sieves are the key to ensuring high efficiency and energy saving of equipment. Our company uses imported high-performance products.
It has the characteristics of strong hardness, low air consumption, high nitrogen recovery rate, and long service life (up to 8 years).

2. Adsorption tower composite bed structure
The adsorption tower in the new pressure swing adsorption nitrogen production device produced by our company adopts a composite bed structure design. The top of the tower is a cylinder type + coconut cushion type automatic
The dynamic compression device has a carbon molecular sieve in the upper middle and a carbon molecular sieve in the lower part (removing less water and CO2). The compressed air is diffused by a special air diffuser and buffered and first enters the carbon molecular sieve to remove trace amounts of moisture. and CO2, and then enter the carbon molecular sieve adsorption layer.
3. Special gas diffusion structure
There is a special airflow diffusion device inside the adsorption tower. First, the compressed air enters from the neck with a cyclone device and diffuses special nitrogen.
Aluminum ceramic balls (utilizing the spherical shape and hardness of the ceramic balls) make the gas flow in an "S" shape when diffusing, and then pass through the double-layer stainless steel wire mesh and activation
The treated molecular sieve is fully in contact with the carbon molecular sieve, which not only greatly reduces the impact of the gas on the molecular sieve, but also makes the gas adsorb
The process is more uniform, which is beneficial to improving the nitrogen production efficiency and the service life of the carbon molecular sieve.

4. Imported pneumatic angle seat valve

Using the world-renowned company Danish ESG stainless steel pneumatic angle seat valve, the opening time is 0.5 seconds.
The normal service life is more than 2 million times. It has simple structure, reliable sealing, quick closing and maintenance.
Features such as simple maintenance are the guarantee for the reliable operation of nitrogen production equipment.
5. Self-operated cylinder pressing device
The adsorption tower adopts advanced cylinder-type automatic compression technology. The device has an automatic replenishment function of molecular sieves. The control system controls the adsorption
The changes of molecular sieves in the tower are highly monitorable.
The automatic compression device uses the working pressure in the adsorption tower as its own compression pressure. When there is a lack of molecular sieve in the adsorption tower, the cylinder operates.
The process will come into contact with the magnetic switch, thus triggering the alarm to remind the user that molecular sieve needs to be added (this alarm will automatically stop after 500 hours,
To protect the molecular sieve), the device is combined with our company's original high-efficiency filling method (patented technology) to make the molecular sieve powdering rate lower, the service life longer, the compression time longer, more reliable and more obvious.

PLC intelligent program controller
Our company configures a PLC control system for the nitrogen production unit. The unit has good controllability, reasonable operation mode, and can
Display various operating parameters, status and fault signals of the equipment. The control system is equipped with an LCD control screen. In addition to the display function, it can also
Parameter setting and control are convenient and flexible on the panel. The main body can realize interlocking start-stop control with the air compressor and remote centralized control.
Remote control start and stop from the central control center.

Original high-efficiency filling method
Our company's original stretch-torsion vibration filling method makes the carbon molecular sieve filling more uniform and dense, and reduces the friction coefficient to the lowest point.
To ensure that the carbon molecular sieve does not pulverize for a long time during the adsorption process.
