Description

Technical Field

[0001] The present invention relates to the technical field of molecular sieve oxygen generation, and more specifically, to a rotary molecular sieve oxygen generator. Background Art

[0002] In the fields of medical treatment, industry, and home healthcare, molecular sieve oxygen generators are widely used as important equipment for obtaining oxygen. Traditional molecular sieve oxygen generators usually adopt a single-tower or double-tower structure for nitrogen-oxygen separation. In the air pretreatment link of existing oxygen generators, the moisture in the air easily affects the adsorption performance and service life of the molecular sieve, resulting in a decline in oxygen generation effect. Therefore, air dehumidification is required.

[0003] In traditional molecular sieve oxygen generation technology, the air dehumidification link has always been the key bottleneck restricting oxygen generation efficiency and equipment stability. Most existing oxygen generators use a single static dehumidification device, which not only has low dehumidification efficiency but also cannot realize the cyclic regeneration and utilization of dehumidification materials, resulting in high equipment maintenance costs and short service life. In addition, traditional dehumidification methods cannot effectively utilize the heat energy generated during the dehumidification process, causing energy waste. Summary of the Invention

[0027] Working principle: The outside air enters the oxygen generator through the air inlet pipeline. The suction pump 4 in the air inlet pipeline sucks in the air, and the air enters the dehumidification chamber 81 of the rotating chamber 8 in the dehumidification chamber 11 through the air inlet pipe 40.

[0028] The heating chamber 80 in the rotating chamber 8 is filled with water-containing dehumidification molecular sieve. The high-temperature hot air blower 23 conveys hot air to the first air chamber 90 through the hot air inlet pipe 24. The hot air enters the heating chamber 80 to heat the water-containing dehumidification molecular sieve, so that the moisture in it evaporates into water vapor. The water vapor is discharged through the water vapor discharge pipe 25 to realize the regeneration of the dehumidification molecular sieve. The rotating chamber 8 rotates under the drive of the rotating motor 3, so that the heating chamber 80 and the dehumidification chamber 81 are alternately connected to the first air chamber 90 and the second air chamber 91 of the air distribution block 9, so as to continuously carry out the dehumidification and regeneration process.

These two separation chambers are filled with oxygen production molecular sieves. Utilizing the difference in the adsorption capacities of the molecular sieves for nitrogen and oxygen, under pressurized conditions, nitrogen is adsorbed by the molecular sieves, and oxygen enters the oxygen transportation main pipe 47 through the first oxygen transportation branch pipe 45 and the second oxygen transportation branch pipe 46, and is finally collected in the oxygen collection chamber 10.

[0030] During the nitrogen-oxygen separation process, the nitrogen adsorbed by the molecular sieves is desorbed under conditions such as decompression. The desorbed nitrogen enters the nitrogen transportation pipe 48 through the fourth three-way valve 62 and the fifth three-way valve 63, and then passes through the third three-way valve 401. Part of it is discharged through the nitrogen discharge port 49, and the other part passes through the connecting pipe 402 and the first three-way valve 20 to enter the cold air inlet pipe 2, and is mixed with the cold air entering the oxygen generator, which can play a certain pressurizing role.

[0031] The oxygen in the oxygen collection chamber 10 is output through the oxygen outlet pipeline. A pressure gauge five 68 and an oxygen detection unit 51 are provided on the pressure measuring pipe 50 in the oxygen outlet pipeline, which are used to detect parameters such as the pressure and concentration of oxygen. The first valve 52 is used to control the discharge of oxygen. After passing through the first valve 52, the oxygen is discharged from the oxygen discharge port 53 for users to use.
