优势特点
- Simple and reliable: modular design, simple process flow; dedicated hydraulic two-eccentric program-controlled butterfly valve, less equipment and maintenance points;
- Easy operation: full automation, one button on/off, oxygen generation within 10 minutes or so, can cut off fault tower for maintenance without shutdown;
- Intrinsic safety: the product is oxygen of normal temperature and pressure which will not result in local accumulation even in case of leakage;
- Good economic benefits: the oxygen generation cost is ~0.3 RMB per standard cubic meter, with less floor area;
- Intelligent power distribution and digitization: equipment butler, easy to maintain in time after warning, mechanical-electrical integration, semi-integration of mechanical and electrical devices, centralized control, elaboration of equipment process, optimization of power consumption;
- Process integration and optimized design: participated by many industrial experts and engineering designers to realize the optimization of equipment selection and process arrangement;
- Engineering project management and project mode: with implementation experience of more than 100 projects of smelting, chemical, polysilicon and other industries home and abroad, the optimization of quality, safety, schedule and other project management links can be ensured.
工作原理
Pressure swing adsorption is a cyclic process in which the pressure variation makes the gas mixture be adsorbed and desorbed in adsorbent alternatively. According to the difference of desorption modes, pressure swing adsorption oxygen generation can be divided into PSA and VPSA. PSA（Pressure Swing Adsorption is the cyclic process in which adsorption is conducted under the pressure relatively higher than normal pressure and desorption is done under the pressure approaching the normal pressure, it is usually used in production of medical oxygen and small scale usage scenarios; VPSA（Vacuum Pressure Swing Adsorption is the process in which adsorption is conducted under the pressure approaching or exceeding the normal pressure, and desorption and regeneration are done under the condition that vacuum is made; in the VPSA cyclic process, the air is supplied by fan, no need for the air being compressed, which is better than PSA in such aspects as production scale and energy consumption, etc.
