Description
This utility model relates to a kind of chemical oxygen generation device.
For studying a kind of easy inexpensive chemical oxygen generation device, consulting various countries' patent documentation learns, as JP61-227903[1986], SU15676482[1990], CN8610450.6, CN89106479.6, the disclosed oxygen generator of CN93106953, all there is following defective in the above-mentioned patent of analysis-by-synthesis, the one, system oxygen raw material is difficult to obtain, or oxygen preparation is discontinuous; The 2nd, the residual liquid that generates behind the system oxygen contains the metal waste liquid, discharges easy contaminated environment; The 3rd, the complex structure of oxygen generator is difficult for producing and operation, uses wayward.
For overcoming the deficiency of above-mentioned oxygen generator, the purpose of this utility model provides a kind of oxygen preparation and device is simple, can make pure oxygen continuously, and novel oxygenerator free from environmental pollution.To be applied to medical first aid oxygen, family health care oxygen, aquaculture and transportation occasion with oxygen, also can be as middle and primary schools' chemical experiment demonstration device.
For achieving the above object, technical solution of the present utility model is finished like this: a kind of easy oxygenerator, comprise reinforced feeder, catalytic reaction chamber and tail washings catcher three parts, and the catheter of connection is set by hydrogen peroxide reservoir and bottom, and the control valve that upward disposes, the top catheter that is positioned at control valve is added with the reinforced feeder that the air pressure balance pipe is formed, make the other end of reinforced feeder catheter be connected in an end of the catalytic reaction tube that catalyst is housed, the other end connects the tail washings collecting tank by airway, and reach the tail washings catcher that sidepiece is provided with oxygen exhaustor and tapping valve composition respectively on its cell body, and integral installation is on body.
The catalytic reaction tube that uses in the described oxygenerator, its draw ratio should 〉=3, can decompose fully when guaranteeing hydrogen peroxide by catalytic reaction tube.
Another program of the present utility model is that the reinforced supply mode of pump is set on the catheter of reinforced feeder.
Characteristics of the present utility model are: have reasonable in design, simple in structure, utilize aqueous hydrogen peroxide solution through the oxygenous principle of catalytic decomposition, achieve continuous oxygen generation, process is controlled, use is easy to operate, can be widely used in medical first aid, family health care, aquaculture, and as functions such as middle and primary schools' chemical experiment demonstration devices.
Embodiment is to this novel being further described in conjunction with the accompanying drawings.
Fig. 1 is the oxygenerator structural representation.
Fig. 2 is another embodiment of Fig. 1.
By shown in Figure 1, oxygenerator mainly comprises reinforced feeder, and catalytic reaction tube and tail washings catcher three parts that solid granular catalyst is housed are formed, and integral body is the vertical structure body.It is to adopt hydrogen peroxide storage bottle 1 (groove or jar), and the transparent plastic catheter 3 of connection is set in its bottom, the transparent body is convenient to observe a speed, control valve 4 is housed on the catheter 3, and be positioned at the top of control valve 4 or the pressure of reservoir 1 is the reinforced feeder that normal pressure is formed, make the other end of the catheter 3 that reinforced feeder draws be connected in an end of the catalytic reaction tube 5 that catalyst is housed, the installation site of catalytic reaction tube 5 should be lower than hydrogen peroxide reservoir 1, to keep certain liquid level poor.The airway 6 that the other end of catalytic reaction tube 5 is provided with connection is connected to tail washings collecting tank 7, and on tail washings collecting tank 7 and sidepiece the tail washings catcher that oxygen exhaustor 8 and tapping valve 9 formed is set respectively, the integral installation that makes its combination is on body.
The feeding quantity control valve 4 that is provided with on the catheter 3 that hydrogen peroxide reservoir 1 bottom connects can adopt pin type or electromagnetic switch valve, also can choose the plastic valve of medical control transfusion.The solid granular catalyst that dresses can catalysis hydrogen peroxide (hydrogenperoxide steam generator) decompose in the catalytic reaction tube 5 is as carrier model Ni, Pd, MnO
2Deng, catalyst shape is spherical, cylindrical, this granule should have resistance to water and certain thermostability, guarantees the clarification of life-time service and tail washings.Particle diameter and catalytic reaction tube 5 diameter ratios answer≤1: 5; Catalytic reaction tube 5 draw ratios should 〉=, to guarantee the existing enough permeabilitys of catalytic bed, can not produce channeling again, can decompose when making hydrogen peroxide pass through catalytic reaction tube 5 fully.The volume of catalytic reaction tube 5 is determined by oxygen making amount, generally between 10l-0.005l, because of exothermic catalytic reaction, chooses catalytic reaction tube 5 and should use metal tube or glass tubing.
The tail washings catcher also has the function of gas-liquid separation, oxygen humidification and gas production written instructions except that having the residual liquid of reception, so tail washings collecting tank 7 should select for use transparent resin material or glass to make, so that observe gas production.
See another embodiment shown in Figure 2.Oxygenerator integral body can be the horizontal type structure body.It is to have done corresponding variation on the basis by above-mentioned vertical structure, the feed way of reinforced supply also can be by the pump feed way except that the dropping mode of utilizing liquid level difference, and the catheter 3 that is positioned at the rear side of control valve 4 is provided with reinforced control pump 10, control pump 10 can be chosen micro centrifugal pump, peristaltic pump or magnetic drive pump, the amount of infusion of pump can be fixed, also can be adjustable, generally between 10 (l/min)-0.01 (l/min).Adopt the installation site between this kind mode oxygenerator each several part not limited by liquid level, be particularly suitable for the big occasion of oxygen consuming amount, as used for aquiculture oxygen, the big I of hopper is determined by oxygen consuming amount, generally between 50l-0.05l.
The employed hydrogen peroxide of oxygen preparation can be common industrial hydrogen peroxide, and its concentration can be chosen wantonly between 50%-5%.
