Pressure swing adsorption nitrogen equipment uses carbon molecular sieve as adsorbent and uses pressure swing adsorption principle to obtain nitrogen. Under a certain pressure, by using the difference of adsorption amount of oxygen and nitrogen in air on the surface of carbon molecular sieve, that is, the diffusion adsorption of oxygen by carbon molecular sieve is far greater than that of nitrogen, the opening and closing of pneumatic valve can be controlled by programming, so as to achieve the process of alternating circulation of tower a and Tower B, pressurized adsorption and decompression desorption under pressure, so as to complete the separation of oxygen and nitrogen and obtain nitrogen with the required purity.
1. The whole machine runs reliably
The combination of advanced nitrogen production process design, gas distribution structure, adsorption tower with compound bed structure, unique carbon molecular sieve filling process, unique carbon molecular sieve protection measures and automatic cylinder compression compensation device, the normal service life of the nitrogen generator can reach more than 10 years.
2. Stable continuous production
The imported PLC control system and the imported pneumatic valve with a switching life of 3 million times are adopted to ensure the continuous and reliable operation of the device.
3. Advanced control system
Siemens PLC control system, stable and reliable, high degree of automation.
Optional touch screen control system, with humanized interface design, multi screen display function, online display of nitrogen purity, flow, pressure, fault signal and other parameters, and online modification of operating parameters, with remote monitoring, remote signal and remote start-up and shutdown functions, high degree of automation, simple operation, can realize automatic unmanned operation, and can be connected with user DCS system Unified control.
It is easy to operate, display intuitively and realize remote monitoring.
The unique on-line analog control display screen can display the system process flow and valve opening and closing status online, which is intuitive and convenient, and has strong monitoring ability.
4. Stable gas quality
The adsorption process with adjustable nitrogen flow and pressure is equipped with automatic interlock air defense device to ensure nitrogen purity and long-term stability of pressure.
5. Low operating cost
Compared with others (including cryogenic nitrogen production, membrane nitrogen production, liquid nitrogen, cylinder nitrogen), PSA nitrogen production costs are lower in small and medium-sized plants.
6. Perfect after sales service
Perfect after-sales service system, quick response mechanism and marketing service network distribution ensure that every customer can use it safely for a long time.
