Nitrogen Application in Grain Storage

Release Time：2019-08-08

　　The air is compressed by a compressor to 7.0–8.5 bar and then passed through a three-stage filtration system, a refrigerated air dryer, and an activated carbon oil remover in the purification system, which remove most of the moisture, oil, and particulate impurities from the air before it is supplied to the downstream nitrogen generator unit.

　　When ambient air enters the two adsorption towers of the nitrogen generator’s main unit, the high-performance carbon molecular sieve—specifically configured within each tower for oxygen adsorption—exhibits differential “selective adsorption” for nitrogen and oxygen under pressure. Through automatic valve switching, the system alternates between pressurized adsorption in one tower and depressurized desorption in the other, thereby accomplishing the pressure-swing adsorption process.

　　In other words, under pressurized conditions, the molecular sieve adsorbs oxygen while allowing nitrogen to pass through, which is then collected and conveyed. Once the adsorption bed reaches saturation, the system automatically switches to another adsorption tower for pressurized adsorption, while the original tower is vented to release the adsorbed oxygen. This alternating, reciprocating cycle enables continuous production of high-concentration nitrogen.

Production and Application of Nitrogen Generators

Pressure Swing Adsorption, or PSA, involves adsorption under relatively high pressure.

Pressure Swing Adsorption Nitrogen Generator Manufacturer

The Tongyue pressure swing adsorption nitrogen generator features an adsorber with a unique structural design: this is the core component that determines the utilization rate of the carbon molecular sieve, the nitrogen recovery rate, and whether the carbon molecular sieve will be crushed. Tongyue’s adsorber boasts a distinctive design, incorporating specially structured steel internal components—gas distributors—at both the upper and lower ends inside the adsorber.
