Background
Pressure Swing Adsorption (PSA for short) is a novel gas Adsorption separation technology, and the operating principle of molecular sieve Pressure Swing Adsorption oxygen production equipment is as follows: after the pressurized air is pressurized by the air compressor, the pressurized air processed by the air pretreatment system is subjected to periodic pressurization on the adsorption tower, so that the pressure in the adsorption tower is increased along with the periodic pressurization. In this case, the molecular sieve absorbs a large amount of nitrogen in the air as the ambient pressure increases, while the oxygen in the air still exists in a gaseous form and is collected through the pipeline, which is an "adsorption" process. When the molecular sieve in the adsorption tower adsorbs nitrogen to a certain degree, the adsorption tower is exhausted and decompressed, the capacity of the molecular sieve for adsorbing nitrogen is reduced along with the reduction of the environmental pressure, the nitrogen is released from the inside of the molecular sieve, and the process is a desorption process. The molecular sieve oxygen generating equipment has the following advantages: firstly, the product has high purity; secondly, the device can generally work at room temperature and low pressure, and the bed layer does not need to be heated when being regenerated, thereby saving energy and being economical; the equipment is simple, and the operation and the maintenance are simple and convenient; fourthly, continuous and circular operation can be achieved, and automation can be achieved completely.
In the application number: CN201922307431.3 discloses a molecular sieve oxygen generator, which comprises: casing one, oxygen concentration sensor, oxygen regulating valve, gas accuse valve, exhaust amortization jar, the adsorption tower, air compressor, the fan, rotatable operating panel, casing two, casing three, casing four, casing five, the heat exchanger, a base, the five and two right angle shape casing four composite tubular structure of a casing, set up oxygen concentration sensor between the outside of casing four and casing one inboard, oxygen regulating valve, as required at the lateral surface installation wireless communication module of another casing four, receive the both-way communication between main control board and high in the clouds server through wireless communication module and be connected, realize data transmission. The utility model discloses can effectively protect the life who prolongs molecular sieve, improve flow control valve's qualification rate, can also realize electronic control and realize carrying out remote monitoring and maintenance to the oxygenerator operational aspect
However, the following disadvantages still exist in the practical use process:
first, the adjuvant therapy is not effective because it simply separates oxygen from air, which usually contains more bacteria and viruses, and cannot sterilize them.
The second, the oxygen production effect is not good because its nitrogen gas that will make oxygen in-process separation directly discharges to the external world, causes nitrogen gas to account for than higher in the oxygenerator surrounding environment after using for a long time easily to nitrogen gas accounts for than higher in making oxygenerator air inlet department inspiratory air, thereby is unfavorable for improving the oxygen production efficiency of oxygenerator when using for a long time.
