Embodiment Construction

[0027] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention discloses a PSA oxygen generator comprising a first module adsorption separator, a second module adsorption separator, a module purge separator, an oxygen production pipeline and a sound-absorbing exhaust pipeline, the first module adsorption separator includes a second module One upper vent and the first lower vent; the second module adsorption separator includes the second upper vent and the second lower vent; the module purge separator includes the third upper vent and the third lower vent; oxygen production One end of the pipeline is connected to the third upper vent, the other end is connected to the first lower vent and the second lower vent, and the silencer exhaust pipeline is connected to the first upper vent and the second lower vent. The two upper vents are connected, and both the first exhaust valve and the second exhaust valve are needle valves. The oxygen content of the PSA oxygen generator can be monitored in real time through the first exhaust valve on the oxygen production pipeline, so as to control the oxygen production effect of the PSA. The opening and closing of the second exhaust valve on the silencer exhaust pipeline can control the gas output, so that Debug the instrument to ensure the safety of the instrument.

Description

technical field [0001] The invention relates to the technical field of oxygen generators, in particular to a 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 oxy...
