Novel PSA (pressure swing adsorption) oxygen generator

Abstract

The invention discloses a novel PSA (pressure swing adsorption) oxygen generator. The novel PSA oxygen generator comprises a first adsorption separator module, a second adsorption separator module, gas holders, gas collection pipes and gas cylinders, wherein the gas holders comprise an upper gas inlet holder, an upper gas outlet holder and a lower gas outlet holder; the gas collection pipes comprise upper gas collection pipes and lower gas collection pipes, the upper gas collection pipes and the lower gas collection pipes are mounted at the upper ends and the lower ends of the first adsorption separator module and the second adsorption separator module respectively and distributed in parallel after mounting, the upper gas inlet holder and the upper gas outlet holder are mounted at two ends of each of two upper gas collection pipes respectively, the lower gas outlet holder is mounted at one end of each of two lower gas collection pipes and located on the same side with the upper gas inlet holder, and the gas cylinders are mounted on the upper gas inlet holder, the upper gas outlet holder and the lower gas outlet holder respectively. The novel PSA oxygen generator has the advantages of small overall size, simple pipelines, simple and stable structure, attractive appearance, low production cost and the like.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a novel PSA oxygen generator. Background technique [0002] For patients with cardiovascular, cerebrovascular and respiratory diseases, as well as officers and soldiers and other staff on duty in severely hypoxic plateau areas, it is necessary to inhale high-purity oxygen. Based on the needs of different situations, the application of oxygen generators is born. [0003] At present, the common oxygen generator is double adsorption tower oxygen generator, which uses air as raw material, molecular sieve as adsorbent, and adopts PSA pressure swing adsorption to produce oxygen away from it. The raw air is first pretreated and then pressurized by the compressor. After the compressed air is filtered, cooled and dehydrated, it enters the adsorption tower equipped with molecular sieves through the inlet valve. The nitrogen in the air is absorbed, and the outflow gas is high-purity oxygen....

AI Technical Summary

Problems solved by technology

Although the above-mentioned technical solution has changed the disadvantages of large volume, complex pipeline arrangement and structure, and high manufacturing and production costs in the prior art to a certain extent, the PSA oxygen generator is still slightly larger in size, with many pipelines and complicated layout. , due to the large number of pipelines, there are many welding points in the pipeline, and the welding cost is high. If the welding is not good, it will cause large welding residual stress, unstable structure, and short service life of the overall equipment; Many, high production cost, and the overall appearance is not beautiful
