difference between PSA and VPSA oxygen production?
How to choose a 5L oxygen concentrator or industrial oxygen molecular sieve?
1、 How many oxygen molecular sieve is needed for a 3L oxygen concentrator?
3L can size: 5.2cmx19cm, requires 500g molecular pulley.
How many molecular sieves are needed for a 2.5 5L oxygen concentrator?
5L can size: diameter 7.8X42cm x height.
Approximately molecular pulley requirement: 2.5 kg.
5L industrial oxygen concentrator
Customer oxygen test 93%
(Small household oxygen concentrator) (Oxygen concentrator customer testing purity>93%)
3、 The difference between VPSA and PSA oxygen production equipment in the industry
VPSA oxygen production equipment (recommended lithium molecular sieve)
① Equipment Introduction and Working Principle
Domestically known as VPSA (Vacuum Pressure Swing Adsorption) oxygen production equipment, low-pressure adsorption vacuum desorption oxygen production equipment. Under low pressure conditions, nitrogen and oxygen in the air are drawn in. After adsorption saturation, the molecular sieve is desorbed under vacuum conditions, and nitrogen gas is discharged from the outlet. Oxygen enters the purification system.
③ Equipment configuration and technical specifications
The VPSA oxygen production equipment
The VPSA oxygen production equipment mainly consists of a blower, vacuum pump, cooler, adsorption system, oxygen buffer tank, and control system.
The technical indicators are:
Product scale: 100-10000Nm3/h
Oxygen purity: ≥ 90-94%, adjustable within the range of 30-95% according to user requirements.
◆ Oxygen power consumption: When the oxygen purity is 90%, the equivalent power consumption of pure oxygen is 0.32-0.37KWh/Nm3.
Oxygen pressure: ≤ 20kPa (can be pressurized)
Annual opening rate: over 95%
PSA oxygen production equipment (recommended 13X-HP molecular sieve)
① Equipment Introduction and Working Principle
PSA (Pressure Swing Absorption) oxygen concentrator, also known as pressure swing adsorption oxygen concentrator in Chinese. The principle is to use the difference in adsorption performance of molecular sieves for different gas molecules to separate gas mixtures. Using air as raw material and efficient and highly selective solid adsorbents, nitrogen and oxygen in the air are separated and selectively adsorbed. Under normal temperature and pressure conditions, PSA specific molecules are used to selectively adsorb impurities such as nitrogen, carbon dioxide, and water in the air, obtaining higher purity oxygen.
③ Equipment configuration and technical specifications
The PSA oxygen production equipment mainly consists of an air compressor, a freeze dryer, a de oiler, an adsorption system, an oxygen buffer tank, and a control system.
The technical indicators are as follows ↓↓
Purity: 93%+2% (standard type is 93%)
Pressure: ≥ 0.2Mpa
Dew point:<-40 ℃ (atmospheric pressure)
Output: 3 to 200 Nm3/h
- What is the service life of molecular sieves?
Usually takes 1 to 3 years, with some customers using it for 5 years.
