Oxygen be Source of life and on the earth the local all too of anoxic or few oxygen many.As urban architecture because the strong air of populous and indoor stopping property in the oxygen level deficiency.Subway tunnel, deep-well and highlands all are the anoxybiotic places.And water is unique inexhaustible resource on the earth.Water H
2To be water be made up of and brine electrolysis can obtain purity is high purity oxygen more than 99.9% 2 parts of hydrogen and 1 part of oxygen O, with the bottleneck of obtaining oxygen two kinds of situations arranged and restrict brine electrolysis in the past, and a kind of is that old-fashioned electrolytic process current consumption is big, and the electrolyzer volume is big, and perishable damage.Another kind is to Duo 1 times the handling problem of hydrogen than oxygen behind the brine electrolysis, hydrogen be flammable explosive gas be can not directly be thrown into airborne.
Summary of the invention:
Purpose of the present invention aim to provide a kind of that can be recycled, reduce power consumption, free of contamination, volume is little, a kind of oxygenerator of lightweight brine electrolysis.
The objective of the invention is to realize by following manner:
The present invention includes electrolyzer, electrolyzer is isolated into water/gas storehouse A by only filling the proton exchange membrane that hydrogen perhaps passes through, B, what be close to the proton exchange membrane both sides is catalysis electrode and conductive electrode successively, the positive pole of electrolyzer is located at water/gas storehouse A, the lower end of water/gas storehouse A links to each other with water tank by channel C, water/gas storehouse A upper end links to each other with the oxygen therapy passage and exports oxygen, the negative pole of electrolyzer is located at water/gas storehouse B, water/gas storehouse B upper end is connected to hydrogen fuel cell by output hydrogen passage and hydrogen fuel cell and supplies raw materials, the power supply of electrolyzer is by duplex feeding, one the tunnel is external direct current, and another route hydrogen fuel cell is isolated to be provided.
Described external direct current is that the 220V alternating-current is provided after the rectifier bridge rectification, and another route hydrogen fuel cell provides through diode-isolated.
Described proton exchange membrane claim again solid electrolyte it be the perfluorinated sulfonic acid polymer film.Its structural formula is:
Airtight waterproof can will be between battery two electrodes well isolation of this film, and hydrogen ion can pass through very smoothly, its thickness is about 150um and physical strength is very high.
Described catalysis electrode is that the spraying platinum powder forms on carbon cloth, and the content of platinum powder is about 0.1-0.25mg.cm
-2Thickness is about about 200um.
Described conductive electrode is to make with the foam nickel strap, and its existing air permeability and good has good electroconductibility again.
During the electrolyzer running, in water/gas storehouse A, inject pure water earlier and on conducting electrode 3, add direct supply again by water tank, at this moment the hydrogen ion behind the brine electrolysis will form pure hydrogen by conductive electrode → catalysis electrode → proton exchange membrane → catalysis electrode → conductive electrode → water/gas storehouse B among water/gas storehouse A, and by being delivered to hydrogen fuel cell by output hydrogen passage on water/gas storehouse B, oxygen remaining among water/gas storehouse A is then by oxygen therapy passage output oxygen, and constantly make up water then oxygen and hydrogen will constantly be exported.
Described hydrogen fuel cell can adopt the structure of electrolyzer, its conducting electrode positive pole links to each other with the positive pole of electrolyzer by diode, its conducting electrode negative pole links to each other with the negative pole of electrolyzer, water/F the lower end, gas storehouse at the anodal place of hydrogen fuel cell links to each other with output hydrogen passage, the upper end of hydrogen fuel cell negative pole place water/gas storehouse E is bubbling air then, and mix with hydrogen and to generate water, the water that produces in the hydrogen fuel cell is back to water tank by passage.
Described hydrogen fuel cell hydrogen mixes with airborne oxygen by conductive electrode → catalysis electrode → proton exchange membrane → catalysis electrode → conductive electrode and generates water and then produce potential difference be about 0.7V in this process between two electrodes, can provide electric current about 300A, as 3 battery series connection then will be obtained 2.1V, the 300A direct supply.
When electrolyzer among the present invention and hydrogen fuel cell together used, the oxygen that produces in electrolyzer was used for output, and the hydrogen of generation is then sent into hydrogen fuel cell, and the electric energy that hydrogen fuel cell produces can continue electrolyzer with electricity, and the water of its generation can be recycled.So recycle incessantly, so promptly solved the problem of outlet of the hydrogen that brine electrolysis system oxygen produced, reduced the cost of brine electrolysis required electric power again greatly, have the effect that kills two birds with one stone.
The liquid that electrode of the present invention contacted is pure water thereby has improved greatly work-ing life that its non-maintaining phase can reach 10-20.And specifically long-pending little, in light weight, power-saving characteristics.For example: 1NM
3The oxygenerator of/h just can be combined with general cabinet air-conditioner, provides purified source of oxygen to the user, and the unit that also can be made into single aerator and various different oxygen-producing amounts offers subway tunnel, mine and high altitude anoxia area and brings benefit to the mankind.Also can be used for the oxygen supply of submarine and high-altitude vehicle.
