Abstract
The utility model relates to a pressure swing absorption air separation system, particularly to a rich oxygen generator, and aims to provide a rich oxygen generator which can improve the recovery rate of rich oxygen and shorten the absorption period. The rich oxygen generator comprises an absorption tower in which an oxygen producing molecular sieve is arranged; an air input device is arranged on the input port of the absorption tower and connected through a pipeline; the input port of the absorption tower is connected with a normal pressure desorption device, the output port of the absorption tower is connected with an electrical valve, and the absorption tower is formed by connecting two absorption tanks in parallel, wherein the diameter height ratio of the two absorption tanks is 1: (1.8-2.5). When the air is separated and absorbed, the two absorption tanks work simultaneously, thus reducing absorption period, and meanwhile the diameter height ratio of the two absorption tanks are controlled within 1: (1.8-2.5), thereby shortening the time in which the air penetrates the absorption bed of the molecular sieve in the absorption tank, increasing the recovery rate of the enriched oxygen, and avoiding prolonging the absorption period caused by excessively high diameter height ratio.

Technical field
The utility model relates to a kind of pressure-swing adsorption air separation system, more particularly relates to a kind of oxygen-enriched generator.
Background technology
Raising along with people's living standard, people are also improving constantly the understanding of ambient air quality importance, air separation, adsorption unit are used increasingly extensive, particularly oxygen-enriched generator is progressively entering fields such as family, office space, but the structure of traditional oxygen-enriched generator all is the alternation of adsorption tower double tower, adsorption cycle is long, and the oxygen enrichment rate of recovery is low, has influenced promoting the use of of oxygen-enriched generator.How further to improve the oxygen enrichment rate of recovery, reducing adsorption cycle is the technical barrier that perplexs the professional and technical personnel for a long time, fails effectively to solve always.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly can improve the oxygen enrichment rate of recovery, shortens the oxygen-enriched generator of adsorption cycle.
The technical solution of the utility model is a kind of oxygen-enriched generator, be provided with the adsorption tower of system oxygen molecular sieve in comprising, the air input unit that on the input aperture of adsorption tower, connects by pipeline, the input aperture of adsorption tower also is connected with the normal pressure desorption apparatus, the delivery port of adsorption tower is connected with electrically-controlled valve, adsorption tower by two blade diameter length ratios 1: the adsorption tanks of 1.8-2.5 are formed in parallel.
Air filter, air compressor, condenser, check valve, air vessel, the electrically-controlled valve of air input unit for being connected in series successively, the output terminal of electrically-controlled valve is connected on the input aperture of adsorption tower, and the normal pressure desorption apparatus is an electrically-controlled valve.
Beneficial effect: the utility model is by changing adsorption tower into by two blade diameter length ratios 1: the adsorption tanks of 1.8-2.5 are formed in parallel, during gas delivery absorption, two adsorption tanks are worked simultaneously, reduced adsorption cycle, blade diameter length ratio with two adsorption tanks is controlled at 1 simultaneously: 1.8-2.5, gas penetrates the molecular sieve adsorption lathe bed in adsorption tanks time shortens, oxygen enrichment rate of recovery height, also avoid simultaneously the excessive prolongation adsorption cycle of blade diameter length ratio, the oxygen enrichment rate of recovery of the present invention can reach 25-35% after testing, and condition has been created in the fields such as family, office space that enter for oxygen-enriched generator.
