The ambient air is compressed and purified to remove oil, water and dust before entering a variable pressure adsorption unit consisting of two adsorption towers filled with carbon molecular sieves (CMS). Compressed air flows from the bottom up through the adsorption tower, during which oxygen molecules are adsorbed on the surface of the carbon molecular sieve, and nitrogen gas flows out from the upper end of the adsorption tower and into the coarse nitrogen buffer tank. After a period of time, the carbon molecular sieve in the adsorption tower is saturated with the adsorbed oxygen and needs to be regenerated. Regeneration is achieved by stopping the adsorption step and reducing the pressure of the adsorption tower. The two adsorption towers alternate for adsorption and regeneration, thus ensuring a continuous output of nitrogen.
1. Fast start-up speed, 15-30 minutes to provide qualified nitrogen gas.
2. Automatic operation of the equipment, the whole process can be realized unattended.
3. Highly efficient molecular sieve filling, tighter, more solid and longer service life.
4. Stable and adjustable pressure, purity and flow to meet the different needs of customers.
5. Reasonable structure, advanced process, safe and stable, low energy consumption.
Industrial processes.
Most of the oil, liquid water and dust are attached to the wall of the container and flow to the bottom of the tank and are discharged from the drainage valve periodically, and part of the airflow enters the compressed air purification system.
The air purification system consists of a cold dryer, three filters with different precision and a de-oilizer. By freezing and dehumidifying and filtering the liquid water, oil and dust in the compressed air from coarse to fine, the compressed air pressure dew point is reduced to 2-10℃, the oil content is reduced to 0.001PPm and the dust is filtered to 0.01μm to ensure the cleanliness of the raw gas entering the PSA nitrogen making machine.   
The purified air enters two adsorption towers in two ways, and is alternately adsorbed and desorbed through the automatic switching of the pneumatic valve on the nitrogen making machine, this process separates most of the nitrogen and a small amount of oxygen in the air, and empties the oxygen-rich air. Nitrogen is enriched at the top of the tower and transported by pipeline to the post-stage nitrogen storage tank, which passes through the flow meter and then enters the gas consumption point.
Scope of application.
A. SMT industry applications: nitrogen-filled reflow and wave soldering, nitrogen can effectively inhibit the oxidation of solder, improve welding wetting, accelerate the wetting speed to reduce the production of tin balls, avoid bridging, reduce welding defects, get better welding quality. Use of nitrogen with a purity greater than 99.99 or 99.9%
II. Semiconductor silicon industry applications: atmosphere protection, cleaning, chemical recycling, etc. for semiconductor and integrated circuit manufacturing processes
III. Semiconductor packaging industry applications: nitrogen packaging, sintering, annealing, reduction, storage. Suzhou Evergrande's purification and pressure change adsorption and nitrogen production machine helps major manufacturers in the industry to win a head start in competition and achieve effective value enhancement.
IV. Electronic components industry applications: selective soldering, purging and packaging with nitrogen. Scientific nitrogen inert protection has proven to be an essential and important part of the successful production of high-quality electronic components.
V. Industrial applications in the chemical and new material industries: the use of nitrogen to create an oxygen-free atmosphere in chemical processes, improve the safety of production processes, power sources for fluid transport, etc. Petroleum: can be used for nitrogen purging of pipeline containers in the system, nitrogen filling and replacement of storage tanks.
