PSA oxygen generator
A PSA oxygen generator is a device that produces high-purity oxygen gas from ambient air. It is commonly used in various industries and applications, including medical facilities, industrial processes, and even for military purposes.
Product Description
PSA oxygen generator
Working principle of PSA pressure swing adsorption oxygen concentrator:
Compressed air is processed by a pre-treatment system to remove solid impurities such as oil and dust, as well as the vast majority of gaseous water, and enters an adsorption tower containing zeolite molecular sieves (ZMS). Nitrogen, carbon dioxide, and water vapor in the air are adsorbed by the adsorbent, while oxygen is separated through the adsorption bed layer. When the impurities adsorbed in the adsorption tower reach a certain level, they enter the atmosphere for desorption and regeneration of the adsorbent. The adsorption separation system consisting of two or three towers is cyclically switched under the automatic control of PLC or DCS system to achieve continuous oxygen production. This process is known as PSA (Pressure Swing Adsorption) principle for oxygen production.
Main technical indicators of the oxygen concentrator:
● Oxygen flow rate: 1-240 m3/h
● Oxygen purity: 25-93%
● Oxygen pressure: 0.45-0.6 MPa
● Dew point: -50
Characteristics of oxygen concentrator:
1. High degree of automation
(1) The equipment is fully automated and fully unmanned.
(2) Easy to operate, easy to start and stop, quick gas production, and gas purity can be adjusted freely within a certain range.
2. Higher reliability
(1) Humanized design of the equipment, reasonable overall layout, compact structure, small footprint, simple and convenient installation.
(2) Advanced oxygen production technology and unique airflow distributor design prevent airflow from short circuiting and channeling, making the airflow flow rate in the adsorption bed more uniform, thereby improving the utilization rate of the adsorbent.
(3) Adopting an automatic compression cylinder device and a unique intake method, the airflow direction inside the adsorber remains unchanged, avoiding fatigue wear of the adsorbent inside the tower and effectively ensuring a lifespan of up to 10 years.
(4) The key components adopt internationally renowned brands, and the valve has a service life of up to 1 million times, ensuring the stable operation of the oxygen production system.
3. More significant commercial value
(1) The on-site industrial oxygen supply system developed according to user needs has been improved from traditional multi tower process to dual tower process, with a new process design and optimized structure, low energy consumption, and low investment.
(2) The system is convenient, fast, and inexpensive for on-site oxygen production. The raw materials come from the air of nature, making it a low-cost oxygen supply method today.
(3) The unique filling and pressing method of the molecular sieve in the oxygen concentrator results in higher density, better efficiency, and longer lifespan.
