Abstract
The utility model relates to a pressure swing adsorption air separation system, which solves the technical problem that the utility model provides a pressure swing absorption air separation system which can cause the enriched oxygen with the oxygen content being more than 21 percent in the absorption tower to be fully recovered and utilized. The pressure swing adsorption air separation system comprises an air filter, an air compressor, a condenser, a check valve, an air tank, an air input and an electrical valve, which are connected to form a filter equipment connected with the input port of the absorption tower, and the output port of the absorption tower is connected with the electrical valve; the input port of the absorption tower is connected with an atmospheric desorption device and is connected with an electrical valve for absorbing enriched oxygen which is connected with the atmospheric desorption device in parallel, so the gas which absorbs the residual enriched oxygen in the absorption tower after the gas is desorbed is discharged through the input port of the absorption port or the desorption port, thus utilizing the enriched oxygen in tower fully, and solving the problem which is not solved effectively for a long time.
Description
Technical field
The utility model relates to a kind of pressure-swing adsorption air separation system.
Background technology
Raising along with people's living standard, people are also improving constantly the understanding of ambient air quality importance, air separation, adsorbent equipment are used increasingly extensive, traditional air-seperation system that gas is separated, adsorbs, after gas absorption, the desorb, the remaining oxygen content in the adsorption tower has been wasted greater than 21% oxygen enrichment, does not fully recycle, this problem is perplexing the technical staff of professional domain always, fails for a long time effectively to be solved.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of pressure-swing adsorption air separation system that the interior oxygen rich gas of adsorption tower is fully recycled.
The technical solution of the utility model is a kind of pressure-swing adsorption air separation system, comprise that the air input filter that air cleaner, air compressor, condenser, check valve, air tank, electrically-controlled valve are formed by connecting is connected on the input port of adsorption tower, the delivery outlet of adsorption tower is connected with electrically-controlled valve, the input port of adsorption tower also is connected with electrically-controlled valve except being connected with the normal pressure desorption apparatus.Described normal pressure desorption apparatus is an electrically-controlled valve.
Beneficial effect: the utility model is by in pressure-swing adsorption air separation system commonly used, the input port of adsorption tower is connected with the electrically-controlled valve that reclaims oxygen enrichment, the interior remaining oxygen enrichment of adsorption tower can be by the input port desorption mouth discharge just of adsorption tower after making gas desorption, make full use of the oxygen enrichment in the tower, solved the problem that effectively solved of failing for a long time.
Description of drawings
Fig. 1 is a pressure-swing adsorption air separation system structural representation of the present utility model
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing
A kind of air separation and adsorption system shown in Figure 1, comprise that the air input unit that air cleaner 1, air compressor 2, condenser 3, check valve 4, air tank 5, electrically-controlled valve 6 are formed by connecting is connected on the input port 11 of adsorption tower 7, the delivery outlet 12 of adsorption tower 7 is connected with electrically-controlled valve 9, the input port 11 of adsorption tower 7 also is connected with normal pressure desorption apparatus 8, and the input port 11 and the normal pressure desorption apparatus 8 of adsorption tower 7 also are parallel with electrically-controlled valve 10.Described normal pressure desorption apparatus 8 is an electrically-controlled valve.
During native system work, air is through air cleaner 1, flow into air compressor 2, through entering air tank 5 through check valve 4 after condenser 3 coolings, enter adsorption tower 7 absorption from air tank 5 effluent airs through electrically-controlled valve 6, the gas of process absorption flows out through the outlet 12 and the electrically-controlled valve 9 of adsorption tower 7, electrically-controlled valve 8 is carried out the normal pressure desorb, oxygen content is discharged less than 21% gas, and electrically-controlled valve 10 is discharged oxygen content in the adsorption towers greater than 21% oxygen enrichment, after oxygen content descends in the tower, electrically-controlled valve 8 is carried out the secondary desorb, made full use of the oxygen enrichment in the adsorption tower, this process enters next do action process after finishing.
