PSA oxygen generator is a kind of equipment that uses the principle of pressure swing adsorption to extract oxygen from the air. Its working principle is to use a special adsorbent (such as molecular sieve) to adsorb nitrogen in the air under a certain pressure, so as to achieve the separation of oxygen and nitrogen.
The working process of PSA oxygen generator:
Compressed air: First, the air is compressed by the compressor to increase the pressure.
Pretreatment: The compressed air passes through the pretreatment device to remove moisture, oil and dust.
Adsorption and desorption: after the pretreatment of the air into the adsorption tower, under a certain pressure, the adsorbent adsorption of nitrogen, the release of oxygen-rich gas. Subsequently, the pressure was reduced to atmospheric pressure, and nitrogen was desorbed from the adsorbent to effect regeneration.
Switching: PSA oxygen making equipment usually uses two towers to work alternately, one tower adsorption, the other tower recovery regeneration.
Storage and delivery: The obtained pure oxygen enters the oxygen storage device and is delivered to the user through the oxygen delivery system.
Application areas of PSA oxygen generator:
Metallurgical industry: iron and steel, copper, aluminum, zinc and other smelting process can be used for combustion, oxidation and other links.
Chemical industry: Oxygen can be used for catalytic, oxidation, synthesis and other chemical reactions.
Environmental protection industry: sewage treatment, waste gas treatment and other processes can be used to improve dissolved oxygen.
Medical industry: the preparation of high purity medical oxygen, used in respiratory therapy, operating room, ICU and other occasions.
Aquaculture: Improve dissolved oxygen in water and promote biological growth.
Food preservation: oxygen and carbon dioxide gas mixture can be used as food packaging preservation gas.
The energy efficiency of PSA oxygen generator is improved by reducing energy consumption and improving oxygen production efficiency through new adsorbents and optimizing processes. Intelligent: Application of Internet of Things technology and artificial intelligence algorithms to achieve remote monitoring, fault diagnosis, automatic adjustment and other functions. Scale: With the expansion of industrial scale, oxygen production equipment will face greater capacity and efficiency requirements. High-purity oxygen production: to meet the needs of high-purity oxygen in specific areas, such as semiconductor manufacturing, medical industry, etc. Green environmental protection: the use of environmentally friendly materials, reduce noise, reduce waste emissions and other aspects of optimization, improve the environmental performance of oxygen equipment.
