Abstract
The utility model relates to an oxygen generator, comprising an electrolytic tank 1. The utility model is characterized in that electrolytic solution loaded in the electrolytic tank is the water solution 2 of alkaline substances, an anode 3 is inserted in the electrolytic solution, and the periphery of the electrolytic tank is provided with an air cathode plate 4. When the utility model is worked, air enters into the inner surface of the air cathode plate 4, under the function of a direct current field, an oxygen dissolving reaction is generated, and further, a reverse reaction is generated on the anode to generate oxygen. The utility model has the obvious advantages of low tank voltage, electricity saving, safe operation, etc.
Description
The utility model relates to a kind of oxygen generator.
The existing device of producing oxygen by brine electrolysis, main drawback is: be to discharge hydrogen simultaneously producing oxygen 1), power consumption is big so on the one hand, and hydrogen is combustiblematerials, in case with leak oxygen and mix chance and will blast when big.
The purpose of this utility model is that a kind of oxygen generator will be provided, and it can directly produce pure oxygen and little power consumption.
The utility model is to constitute like this, and it comprises electrolyzer, it is characterized in that: 1) electrolytic solution of containing in the electrolyzer is the aqueous solution of alkaline matter, 2) be plugged with anode in the electrolytic solution, the perimembranous of electrolyzer has the air cathode plate.
Below in conjunction with drawings and Examples the utility model is specifically described.
Fig. 1 is embodiment one organigram,
Fig. 2 is embodiment two organigrams.
With reference to Fig. 1, embodiment one comprises electrolyzer 1, it is characterized in that: 1) electrolytic solution of containing in the electrolyzer is the aqueous solution 2,2 of alkaline matter) be plugged with positive plate 3 in the electrolytic solution, the perimembranous of electrolyzer has air cathode plate 4.(the air cathode plate among Fig. 1 is by waterproof ventilative layer, and conductive mesh and Catalytic Layer are formed).
When embodiment one acquisition operating voltage, air admission is to the internal surface of the air cathode plate 4 that contacts with electrolytic solution 2, and generation dissolved oxygen reaction under the effect of DC electric field, (O
2+ 2H
2O+4e → 4OH
-) reversed reaction takes place on anode then, emit oxygen at last.
Embodiment two is improved to constitute on the basis of the structure of embodiment one, and its purpose of design is in order to replenish moisture that the heat that produces because of reaction evaporates or that taken away by oxygen at any time, with the concentration substantially constant of assurance electrolytic solution.With reference to Fig. 2, embodiment two comprises electrolyzer 7, it is characterized in that: 1) electrolytic solution of containing in the electrolyzer is the aqueous solution 2 of alkaline matter, 2) be plugged with anode 3 in the electrolytic solution, the perimembranous of electrolyzer has air cathode plate 4,3) have air chamber 12 on the liquid level of electrolytic solution, electrolyzer is provided with water tank 5, the liquid adding hole 11 that water tank is provided with oxygen outlet 6 and has tank lid 10; Offer moisturizing passage 9 at the bottom of the water tank towards air chamber; Be provided with upper port in the electrolyzer and be upward through water tank bottom plate and surface, the vertical tube 8 of electrolytic solution is stretched in the lower end.
Than embodiment one, the work characteristics of embodiment two is: 1) oxygen that produces in the electrolyzer just through oxygen outlet, thereby goes out oxygen quality height after alkaline nuisance is removed in the water tank washing.2) moisture in electrolytic solution reduces the liquid level decline that (because consumption in operation) is electrolytic solution, the air pressure of air chamber 12 just decreases, water in the water tank just flows into electrolyzer by passage 9, liquid level until electrolytic solution rises to original position (at this moment, air pressure in the air chamber recovers, thereby the cloudy water that has ended in the water tank flows into electrolyzer).Therefore, embodiment two can add water automatically, to keep the stable of concentration of electrolyte.
The utility model simple structure, easy to use, go out oxygen quality height, than the device of producing oxygen by brine electrolysis, it is low also to have a bath voltage, economize on electricity, the remarkable advantage that waits safe and reliable to operation is a kind of economic and practical novel oxygenerator.
Claims (3)
