PSA Pressure Swing Adsorption Oxygen Generator Working Principle: Compressed air is pre-treated to remove oil, dust, and other solid impurities, as well as most of the gaseous water, before entering the adsorption tower filled with Zeolite Molecular Sieve (ZMS). Nitrogen, carbon dioxide, and water vapor in the air are adsorbed by the adsorbent, while oxygen passes through the adsorption bed and is separated. When the adsorbed impurities in the tower reach a certain level, they undergo atmospheric desorption and regeneration. The adsorption separation system, consisting of two or three towers, operates in a continuous cycle under the automatic control of a PLC or DCS system to produce oxygen continuously.
Oxygen Generator Features:
High level of automation
1. Equipment is fully automated with unattended operation.
2. Simple operation, easy start/stop, quick gas production, and adjustable purity within a certain range.
Higher reliability
Humanized design of the equipment, with a reasonable overall layout and compact structure, occupies less space, and is easy to install.
2. Advanced oxygen production technology with a unique air flow distributor design, preventing short-circuiting and channeling of air flow, resulting in more uniform flow velocity within the adsorption bed, thereby enhancing the utilization rate of the adsorbent.
3. Utilizing an automatic clamping cylinder and a unique intake method, the air flow direction within the adsorber remains constant, preventing fatigue wear of the adsorbent inside the tower. This effectively ensures a service life of up to 10 years for the adsorbent.
4. Critical components are sourced from internationally renowned brands, with valves boasting a lifespan of up to 1 million cycles, ensuring stable operation of the oxygen production system.
(3) Advantages
Boao Gas offers an on-site industrial oxygen supply system tailored to customer needs, improved from traditional multi-tower technology to double-tower technology, featuring a completely new process design and optimized structure, with low energy consumption and cost-effective investment.
2. Convenient, quick, and cost-effective on-site oxygen generation, using air as raw material from nature, is a low-cost oxygen supply method in today's market.
3. Oxygen generator features unique filling and compression of the molecular sieve, offering higher density, improved efficiency, and extended lifespan.
Specific applications of oxygen:
Wastewater Treatment: Oxygen-rich aeration of activated sludge, pond aeration, and ozone sterilization.
Electric Furnace Steelmaking: Decarburization, oxygen-assisted combustion heating, slag foaming, metallurgical control, and subsequent heating.
Non-ferrous metal smelting: Refining copper, zinc, nickel, lead, etc., requires oxygen enrichment, and PSA technology is gradually replacing the cryogenic method.
Cutting Processing: Oxygen enrichment for field steel pipe and steel plate cutting; portable or small-scale oxygen generators can meet the requirements.
Aquaculture: Oxygen-enriched aeration increases dissolved oxygen in water, significantly boosting fish yield, providing oxygenation for live fish transport, and enabling intensive fish farming.
Oxygen concentrators, hyperbaric chambers, oxygen bars, oxygen therapy centers, etc., equipped with activated carbon filters can produce oxygen that meets the national PSA oxygen concentrator technical standards. Glass melting: Oxygen aids combustion and dissolution, cuts, increases glass production, and extends furnace life. Pulp bleaching and papermaking: Chlorine bleaching converted to oxygen-enriched bleaching, providing inexpensive oxygen, and wastewater treatment. Petrochemical and chemical industry oxygen: Oxygen reactions in the petrochemical process use oxygen-enriched instead of air for oxidation, which can increase reaction speed and chemical product yield. Ore processing: Used in gold production processes, it can improve the recovery rate of precious metals. Fermentation: Oxygen-enriched instead of air supplies oxygen to aerobic fermentation, significantly improving efficiency. Drinking water: Supplies oxygen to ozone generators for sterilization.
