Be described further according to structure and the embodiment of specific embodiment below in conjunction with accompanying drawing the designed small-sized oxygen enricher of the utility model.
Small-sized oxygen enricher as shown in Figure 1, mainly constitute by clarifier 1, air dryer 2, air compressor 3, cooler 4, adsorption column 6,7, magnetic valve 5,8, check valve 9,10, air accumulator 11, pressure-reducing valve 12 and water container 13, above-mentioned each parts are installed in the casing, and the single chip machine controlling circuit that is used to control magnetic valve 5,8 also is installed in the casing.Have air inlet and gas outlet on the casing, clarifier 1, air dryer 2 and air compressor 3 are by the pipeline series connection, and clarifier 1 is communicated with the air inlet of casing.Air compressor 3 is again by pipeline connect successively cooler 4 and adsorption column, two adsorption columns 6,7 are parallel in the gas piping, in the pipeline of the front end of adsorption column 6,7 two-position-five-way solenoid valve 5 is installed, be used to control the engineering process of adsorption column 6,7, adsorption column 6,7 is connected with air accumulator 11 through corresponding check valve 9,10, air accumulator 11 is connected with pressure-reducing valve 12, and pressure-reducing valve 12 is passed in the water container 13 by connecting line, and water container 13 is connected with gas outlet on the casing.Between the adsorption column 6,7 two-position three way magnetic valve 6 is installed, with the control gas flow.Single chip machine controlling circuit is used to control the course of work of complete machine.The operation principle of this small-sized oxygen enricher is: outside air enters air compressor 3 through casing air inlet, clarifier 1, air dryer 2 and carries out the air compression, after compressed air comes out from compressor 3, enter adsorption column 6 through subcooler 4, magnetic valve 5, the pressure of adsorption column 6 raises, through after the selective absorption of molecular sieve, oxygen rich gas outputs to air accumulator 11 by check valve 9, adsorption column 7 is resolved by another passage exhaust of magnetic valve 5 simultaneously, and the gas that is adsorbed in the molecular sieve in the adsorption column 7 is drained; When adsorption column 6 pressurization absorption, after adsorption column 7 is resolved a period of time, open magnetic valve 8, with the part oxygen-enriched air in the adsorption column 6 adsorption column 7 is carried out flyback, the residual gas in the adsorption column 7 is discharged; After flyback a period of time, magnetic valve 8 cuts out, magnetic valve 5 commutations, be adsorption column 7 inflations, make adsorption column 7 superchargings absorption, after the absorption of the molecular sieve property selected, oxygen rich gas outputs to air accumulator 11 through check valve 10, adsorption column 6 is resolved through another passage exhaust of magnetic valve 5 simultaneously, and the gas that is adsorbed in the adsorption column 6 is drained; When adsorption column 7 pressurization absorption, after adsorption column 6 is resolved a period of time, open magnetic valve 8, with the part oxygen-enriched air in the adsorption column 7 adsorption column 6 is carried out flyback, the residual gas in the adsorption column 6 is discharged; After flyback a period of time, magnetic valve 8 cuts out, and magnetic valve 5 commutates, and begins the absorption parse operation of following one-period.The above-mentioned action that goes round and begins again promptly can constantly obtain oxygen rich gas.
The control circuit of this small-sized oxygen enricher as shown in Figure 4, wherein U1 is a single-chip microcomputer, U2 is a timer, 01,02 is the optoelectronic controlled silicon trigger, S1, S2 are controllable silicon, DZ1, DZ2 are magnetic valve, L1 is a working station indicator.
In transformation absorption single chip machine controlling circuit shown in Figure 4, single-chip microcomputer U1 controls the action of magnetic valve in the pressure-swing absorption process by the requirement of transformation adsorption process.When the P22 of single-chip microcomputer U1 mouth output high level, optoelectronic controlled silicon trigger 01 does not have triggering signal output, and controllable silicon S1 is not triggered, and the coil of magnetic valve DZ1 must not be electric, and DZ1 is in off-position; When the P22 of single-chip microcomputer U1 mouth is output as low level, optoelectronic controlled silicon trigger 01 output triggering signal, controllable silicon S1 is triggered, conducting, and magnetic valve DZ1 gets electric, is in "on" position.Equally, the P23 mouth of single-chip microcomputer U1 output varying level is by the duty of optoelectronic controlled silicon trigger 02 control magnetic valve DZ2.According to the needs of pressure swing adsorption technique parameter, make full use of the timing function of single-chip microcomputer, the design corresponding control programs makes the requirement work of magnetic valve by transformation absorption.In control system, be provided with timer U2, the service time of molecular sieve is used in the absorption of record transformation, when molecular sieve reached service life, the P20 mouth of single-chip microcomputer U1 provided a pulse signal, the relay indicating light L1 warning of glimmering, and when molecular sieve was in the service life scope, indicator lamp L1 was bright.
When adopting pressure swing adsorption method to carry out the enrichment of oxygen, the structure of adsorption column has direct relation to the output of producing oxygen concentration and oxygen-enriched air, it is low that the unreasonable meeting of structure choice causes producing oxygen concentration, phenomenons such as oxygen-enriched air output is few, therefore when carrying out the design of pressure swing adsorption method oxygenerator, the structural design of adsorption column is crucial.Adopt pressure swing adsorption method to produce oxygen-enriched air, the height/footpath of adsorption column be than should specifically selecting according to practical application, and generally height/footpath is than more than 3.For reducing volume, the adsorption column that adsorption column 6,7 adopts as shown in Figure 2 in this small-sized oxygen enricher is double-deck adsorption column, and 21 is air inlet in the drawings, and 22 is gland, and 23 is urceolus, and 24 is molecular sieve, and 25 is inner core, and 26 is the gas outlet.Fill molecular sieve 24 in tube 23,25 and between the tube 23,25, inner core 25 1 ends and urceolus 23 end cap seal, air can only be flowed in a direction indicated by the arrow, like this, the adsorption column of equal height, after adopting multilayer adsorption column structure, be equal to height/footpath of having increased adsorption column than, improved the effect that transformation is adsorbed.For further increase adsorption column height/footpath than, can also increase the adsorption column number of plies as stated above.Such adsorption column not only volume reduces, and can also guarantee to make the oxygen effect preferably, makes the oxygen enricher miniaturization.In oxygen enricher, adopt two adsorption columns 6,7 alternately to make oxygen in addition, guaranteed continuous supply oxygen-enriched air.This small-sized oxygen enricher can be widely used in places such as family, public place and hospital, hotel.
Embodiment 3
Small-sized oxygen enricher as shown in Figure 1 can also be positioned over clarifier 1, air dryer 2 and compressor 3 in another outer housing of casing, and its pipeline connecting mode is constant, thereby forms split type oxygenerator.The small-sized oxygenerator of this kind can be positioned over the part of compressor outdoor, so more helps indoor oxygenation, and noiselessness.
