Abstract

The invention discloses a portable oxygen generator, which includes at least one set of separation mechanism and oxygen storage tank, the separation mechanism is connected with the oxygen storage tank; the separation mechanism includes an air bag and a molecular sieve tank, the molecular sieve tank is filled with molecular sieve for adsorption, and the air bag has an air inlet And the exhaust port, the valve group includes a first single valve and a second single valve, the airbag is connected to the molecular sieve tank through the first single valve, and the two ends of the molecular sieve tank have at least one exhaust port respectively, wherein the exhaust port at the connection end of the airbag There is a second single valve, the exhaust port at the other end is connected to the oxygen storage tank, the inner space of the airbag is compressed and expanded once, and the molecular sieve in the molecular sieve tank is also adsorbed and desorbed once. Beneficial effects of the present invention: low noise, low heat generation, simple structure; the working process of the airbag is used to synchronize the working process of the molecular sieve, eliminating the need for corresponding electronic sensors, single-chip microcomputers, multi-channel solenoid valves and complicated control circuits in traditional devices; Airbag compression and expansion can be realized manually, and it can work without power under special conditions.

Description

technical field [0001] The invention relates to a gas separation device, in particular to an oxygen generator. Background technique [0002] Pressure swing adsorption (abbreviated as PSA), as a gas separation technology, has attracted the attention of the industrial circles of various countries, and has developed rapidly. Its working principle is: the gas mixture is separated by using the difference in the adsorption performance of the adsorbent molecular sieve to different gas molecules. After the adsorption balance, according to the different characteristics of the adsorption amount of the molecular sieve at different pressures, the pressure is reduced to make the molecular sieve relieve the adsorption of the gas. Adsorption, this process is called regeneration. At present, pressure swing adsorption devices usually use two or more towers connected in parallel, so that pressure adsorption and decompression regeneration can be performed alternately, so as to obtain continuo...
