Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of pure hydrogen pure oxygen high-temperature battery system, comprise pure hydrogen generation module 1, pure oxygen generation module 2 and high temperature proton exchange film pile 3, described pure hydrogen generation module 1 comprises methanol reformer, described pure oxygen generation module 2 is connected with methanol reformer, in described methanol reformer, generating portion oxidation and oxyreforming reaction release heat provide heat power for pure hydrogen generation module 1 and pure oxygen generation module 2, are provided with the methyl alcohol filter for filtering methanol-water in described pure hydrogen generation module 1.
Pure hydrogen generation module 1 comprises the methanol pump, methyl alcohol filter, methanol reformer and the hydrogen gas segregator that are linked in sequence, described pure oxygen generation module 2 comprises the oxygen generator be connected with methanol reformer, described methanol reformer provides heat for methyl alcohol filter, oxygen generator and hydrogen gas segregator, and described hydrogen gas segregator and oxygen generator are connected with high temperature proton exchange film pile 3 respectively.
Hydrogen gas segregator is arranged in oxygen generator.Because the temperature requirement of separating hydrogen gas is at about 480 DEG C, the temperature requirement of oxygen separation is at about 600 DEG C, separately heating is carried out to carry out oxygen separation and its cost of hydrogen is very high and efficiency is lower to these two parts, utilize the heat discharged in methanol reformer to carry out the separating-purifying of oxygen and hydrogen simultaneously, efficiency is very high, and energy-conserving and environment-protective.
Palladium-based composite membrane is provided with in hydrogen gas segregator.Palladium-based composite membrane has very high saturating hydrogen speed and hydrogen permeation selectivity and good chemistry and thermal stability, is applicable to very much the purification of hydrogen.
Operation principle of the present invention is: methanol-water pumps in methyl alcohol filter by methanol pump from methyl alcohol bucket, methanol-water by thermal evaporation again condensation obtain the methyl alcohol of purity about 99%, pure methyl alcohol enters methanol reformer and to be oxidized with the oxygen generating portion that oxygen generator produces and oxyreforming reaction obtains hydrogen, carbon monoxide and carbon dioxide, this reaction is exothermic reaction, the hydrogen obtained, carbon monoxide and carbon dioxide enter hydrogen gas segregator and purify, in the present invention, hydrogen gas segregator is arranged in oxygen generator, the benefit of such setting is, because separating hydrogen gas needs to carry out at the temperature of 480 DEG C, oxygen separation needs to carry out at the temperature of 600 DEG C, hydrogen gas segregator is arranged in oxygen generator, the heat in oxygen generator can be made full use of, do not need additionally to arrange heater again.In these three steps of separation of hydrogen in the separation of oxygen in the filtration purification of methanol-water, oxygen generator, hydrogen gas segregator, all heats are all the heats produced from reforming reaction in methanol reformer, the waste heat that the present invention utilizes methanol reformer to produce is to obtain pure hydrogen pure oxygen, make it possible to be applied in on-vehicle fuel, drastically increase the generating efficiency of fuel cell.
Methyl alcohol filter of the present invention comprises and is heated evaporation module 4 and evaporates the condensation module 5 that module 4 is connected with being heated, be heated evaporation module 4 comprise from methanol reformer absorb heat heat transfer original paper 41 and carrying methanol feedstock hopper 42, methyl alcohol enters condensation module 5 by after thermal evaporation from hopper 42, condensation module 5 comprises condensation original paper 51 and collecting chamber 52, and methanol steam enters collecting chamber 52 through condensation original paper 51 post liquefaction.
First the operation principle of methyl alcohol filter mainly utilizes methanol pump to pump in hopper 42 by methanol feedstock to be purified, in the course of the work, the heat transfer original paper 41 be heated in evaporation module 4 absorbs heat from methanol reformer, because what carry out in methanol reformer is partial oxidation and oxidation and reformation exothermic reaction, more heat can be discharged, heat transfer original paper 41 absorbs heat and passes to methanol feedstock to be purified from methanol reformer, because the boiling point of methyl alcohol is between 60 ~ 70 DEG C, so methyl alcohol is by forming pure methanol steam after thermal evaporation and entering condensation module 5, the boiling point of impurity and water is general higher, still can stay in hopper 42.Methanol steam is condensed into liquid and enters collecting chamber 52 after condensation original paper 51, and the pure methyl alcohol in collecting chamber 52 for follow-up, thus can complete the filtration purification of methyl alcohol.Methyl alcohol through purifying can better prepare pure hydrogen.
Heat transfer original paper 41 is carbon nano-tube.Carbon nano-tube has heat transfer efficiency very efficiently, in the present invention, the temperature range of accurate Heat Transfer Control original paper 41 can be realized by the specification designing carbon nano-tube, advantage can be merely able to methyl alcohol to carry out by thermal evaporation being heated to reach in evaporation module 4 exactly, and impurity and water can not be subject to thermal evaporation.One as above-mentioned carbon nano-tube is out of shape, and the heat transfer original paper 41 in the present invention can also be the cellular heat transfer plate of nanoscale.Same, the temperature range of heat transfer original paper 41 can be ensured
The above is only the preferred embodiment of the present invention, protection scope of the present invention be not only confined to above-described embodiment, and all technical schemes belonged under thinking of the present invention all belong to protection scope of the present invention.It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications also should be considered as protection scope of the present invention.
