An anti-molecular sieve pulverization oxygen production host adsorption tower

Abstract

The invention belongs to the technical field of medical oxygen making, and provides a molecular sieve pulverizing-proof oxygen-making main engine adsorbing tower with simple structure and convenience in maintenance. The molecular sieve pulverizing-proof oxygen-making main engine adsorbing tower comprises a barrel shell, an upper cover and a molecular sieve, wherein the molecular sieve is mounted at the inner part of the barrel shell; the upper cover is mounted at the upper part of the barrel shell; the molecular sieve is fixed at the inner part of the barrel shell through an upper pattern card and a lower pattern card; small holes are formed in the pattern cards to enable the air to flow freely; silk nets are filled in the inner parts of the small holes; a cylinder with the same shape with a barrel body is arranged at the upper part of the barrel shell; the upper cover is fixed at the upper part of the barrel shell through screw bolts; a threaded hole is formed in the center of the upper cover; a screwed plug is mounted in the threaded hole; and the screwed plug is an inner hollow screw bolt. The tower is mainly applied to the technical field of the medical oxygen making, solves the trouble of filling and extracting the molecular sieve, and improves the oxygen producing quality of an oxygenerator.

AI Technical Summary

Problems solved by technology

[0002] Due to the harsh installation conditions and high system costs of liquid oxygen stations for medical oxygen production, many users cannot bear it. With the rapid development of the international and domestic oxygen production industry, the emergence of medical PSA oxygen production technology has effectively alleviated this problem. However, there are still many problems to be overcome in the transformation process of this technology. These problems will directly affect the oxygen production quality of the oxygen generator. Whether the entire PSA oxygen industry exists or not, in order to solve these problems, our company has carried out a series of experiments and research

[0003] 1. The upper part of the main body of the existing oxygen generator has an elliptical structure, which is much smaller than the radius of the cylindrical structure of the oxygen generator itself, so it is very inconvenient to fill the molecular sieve in the oxygen generator

[0004] 2. Molecular sieve, as the core material of the oxygen generator, has high economic value and practical value. Since oxygen production needs to be carried out under high pressure, the flowing high-pressure gas can easily drive the molecular sieve to move back and forth, causing the molecular sieve to pulverize and directly reduce the oxygen production. Purity, reduce product quality, and even reduce the service life of oxygen generators, resulting in huge economic losses

[0005] 3. When filling the molecular sieve, due to the limitations of the structural design of the oxygen generator, it takes a lot of time to fill the molecular sieve, and if it is exposed to the air for a long time, it will absorb moisture in the air, which is a kind of damage to the molecular sieve that is afraid of water. Affect its use effect and life

[0006] 4. When replacing the molecular sieve, it is not easy to pour out the molecular sieve, which brings a lot of inconvenience to the follow-up maintenance

[0007] 5. When the oxygen generator equipment produces oxygen, there is no real-time monitoring of the internal oxygen production situation, and measures cannot be taken in time

[0008] 6. Due to the large size of the main body of this oxygen generator, which weighs more than one ton, when used in plateau areas, after a long period of transportation bumps, hoisting, etc., it is easy to damage the molecular sieve and affect the quality of use

[0009] 7. Due to this structural design, its internal structure cannot be replaced and becomes a one-time structure, resulting in an increase in user costs
