The VPSA oxygen generation equipment is an efficient oxygen generation technology, widely used in industries such as industry, chemical engineering, metallurgy, and aviation. Its main function is to extract oxygen from the air and provide a stable oxygen supply. This article will introduce in detail the working principle, main components, and application fields of the VPSA oxygen generation equipment.
1.Working Principle
The working principle of the VPSA oxygen generation equipment is based on the pressure oscillation adsorption technology. Specifically, this technology selectively adsorbs oxygen and nitrogen in the air using adsorbents. By taking advantage of the different gas properties at different pressures, oxygen is separated and extracted.
The VPSA system compresses the air to a certain pressure using a compressor and then sends it into the adsorption tower. The adsorption tower is filled with specific adsorbents, usually zeolites or activated carbon, etc. These adsorbents have different adsorption capabilities for oxygen and nitrogen, so under certain pressure, oxygen will be adsorbed by the adsorbents, while nitrogen will be discharged.
Next, as the compressed air enters, the system automatically adjusts the pressure, which is called “pressure oscillation”. During the high-pressure stage, oxygen is adsorbed and nitrogen is discharged; during the low-pressure stage, the adsorbents release the adsorbed oxygen and return to the initial state. Through this cycle, the VPSA equipment can continuously extract oxygen from the air.
2. Main Components
The main components of the VPSA oxygen generation equipment include the following parts:
(1) Air compressor: used to compress the air in the atmosphere to a certain pressure, so that the subsequent adsorption process can be carried out.
(2) Adsorption tower: the core part of the equipment, filled with adsorbents, whose function is to separate oxygen and nitrogen. The adsorption tower is usually composed of two or more tower bodies to achieve continuous oxygen production.
(3) Oxygen storage tank: used to store the produced oxygen to meet the needs of users. The capacity of the oxygen storage tank is determined according to the actual needs of the users.
(4) Control system: used to monitor and regulate the operation status of the equipment to ensure it operates in an optimal state. The control system is usually equipped with sensors and automated control devices to improve the operating efficiency of the equipment.
(5) Pipeline system: connects various components and is responsible for the transportation and distribution of gases.
