High-purity nitrogen generator

Working Principle of PSA (Pressure Swing Adsorption) Nitrogen Generation

The PSA nitrogen generator is an automated system that utilizes carbon molecular sieves as the adsorbent. It separates nitrogen from air by applying the principles of pressurized adsorption and depressurized desorption to capture and release oxygen. Carbon molecular sieves are black, cylindrical granular adsorbents—produced primarily from coal through grinding, oxidation, molding, carbonization, and specialized pore-structure processing—featuring a surface and interior riddled with micropores. By exploiting the slight differences in the kinetic diameters of oxygen and nitrogen, as well as specific pore-size distribution characteristics, these sieves enable the kinetic separation of O₂ and N₂.

Precision Manufacturing

1. Nitrogen Purity Monitor

Real-time monitoring of nitrogen purity; ensures production safety and quality; supports data recording and traceability.

2. Solenoid Valve

Reliable multi-point control ensures the proper functioning of the adsorption tower switching cycle.

3. Glass Rotameter

Monitors and displays instantaneous nitrogen flow rate; enables flow adjustment and control.

4. Pressure Regulating Valve

Highly responsive; features an efficient air filter to ensure effective gas drying.

5. Silencer

A device that blocks sound propagation while allowing airflow; reduces noise generated by the discharge of regeneration gas from the adsorption dryer.

6. Angle Seat Valve

Provides precise control over nitrogen flow (on/off and regulation) and withstands high pressure, ensuring system safety.
