Abstract
The utility model relates to a differential pressure balance hydrogen and oxygen generator, which comprises an electrolyte and oxygen storage tank, an electrolyte and hydrogen storage tank, a cathode electrode, an anode electrode, a diaphragm, a pipeline, a valve, etc., wherein, the cathode electrode and the anode electrode are honeycombed woven meshes or hauling meshes; a differential pressure balance valve is arranged between the electrolyte and oxygen storage tank and the electrolyte and hydrogen storage tank. A differential pressure balancer of the utility model which is used simultaneously with the honeycombed electrodes can enhance the pressure of hydrogen evolution and oxygen evolution to ensure that asbestos membrane operates under the condition of no differential pressure and to realize that a water electrolysis hydrogen and oxygen generator safely operates under middle and high pressure. The differential pressure balance hydrogen and oxygen generator can be freely moved, which is convenient for the demands of hydrogen and oxygen for various users.
Description
The utility model relates to system gas equipment, particularly a kind of pressure balance oxyhydrogen generator.
Usually be to make the medium barrier film with the asbestos cloth between the negative electrode anode in the hydro-electrolytic hydroxide generator electrolyzer, electrolysis produces hydrogen, oxygen respectively.Under normal pressure, boost to storage sale in the steel cylinder by force (forcing) pump.This technology power consumption is big, efficiency of conversion is low, and electrolyzer is fixed not removable, brings inconvenience to the user.In addition, owing to generate 2H behind the brine electrolysis
2And O
2And because the user is to the demand of hydrogen and oxygen different amounts and different pressures, so will form pressure reduction between cathode of electrolytic tank and the anode in the water electrolysis process, and very easily make the barrier film breakage cause hydrogen, oxygen (anode and cathode) gas blowby or the hydrogen-oxygen security incident that leads to out of proportion if pressure reduction is excessive.
The purpose of this utility model is intended to propose a kind ofly can improve liberation of hydrogen greatly, analyse oxygen pressure, guarantees the pressure balance oxyhydrogen generator that the asbestos film is worked under no pressure reduction condition, to overcome weak point of the prior art.
The purpose of this utility model can realize by following proposal.
The pressure balance oxyhydrogen generator comprises storage electrolytic solution, oxygen canister and storage electrolytic solution, hydrogen gas tank, the yin, yang electrode, and barrier film, pipeline, and valve etc.It is characterized in that the yin, yang electrode is the mesh grid of honeycomb structure or draws in the net.And between storage electrolytic solution, oxygen canister and storage electrolytic solution, hydrogen gas tank, be provided with a differential pressure balancing valve.
Below in conjunction with embodiment of the present utility model and accompanying drawing, the pressure balance oxyhydrogen generator is described in detail.
Fig. 1 pressure balance oxyhydrogen generator synoptic diagram;
Fig. 2 pressure balance oxyhydrogen generator honeycomb electrode synoptic diagram;
Fig. 3 pressure balance oxyhydrogen generator differential pressure balancing valve synoptic diagram.
Pressure balance oxyhydrogen generator of the present utility model, basic identical with general oxyhydrogen generator structure.Also comprise storage electrolytic solution, oxygen canister 2 and storage electrolytic solution, hydrogen gas tank 4, yin, yang electrode 5,7, barrier film 8, pipeline 1, and valve 3 etc.Its difference is that its yin, yang electrode is the mesh grid of honeycomb structure or draws in the net 9, mesh grid or draw in the net by multi-disc silk footpath 0.5mm greatly most, and the aperture is that the spot welding that superposes anyhow of the net sheet of 0.3-0.5mm forms.Active material of cathode is HAC, and anode is a raney ni, and barrier film 6 between the yin, yang electrode is the asbestos paper material.Also be provided with a differential pressure balancing valve between this external storage electrolytic solution, oxygen canister and storage electrolytic solution, the hydrogen gas tank.Differential pressure balancing valve is by sampling thief single-pass valve seat 10, sampler two-port valve seat 13, and sampling valve rod 11 and elastomeric switch 12 are formed.Wherein, there is a sampling thief hole 16 at the sampling thief single-pass valve seat center of differential pressure balancing valve, the "T"-shaped sampling valve rod of suit in the hole; There is sampler hole 14 at the sampler two-port valve seat center of differential pressure balancing valve, and there is venting hole 15 in the outside; And dismantled and assembled and fixing between the sampling thief single-pass valve seat of differential pressure balancing valve and the sampler two-port valve seat, as passing through the screw thread spinning.Between the two, be fixed with elastomeric switch 12.
The utility model is to add the principle that the oxyhydrogen reaction generates electricity and water under certain condition with reference to hydrogen-oxygen fuel cell, adopt asbestos paper to make barrier film, the HAC active cathode material is made negative pole, the Raney's nickel anode material is done anodal, according to technology and needs, two electrodes are made certain geometrical shape, and electricity decomposes the H in the water outlet in containing 25% alkaline solution electrolyzer
2Molecule and O
2Molecule, and obtain hydrogen and oxygen more than 99.9% purity.At work, when the sampling thief mouth pressure was higher than the sampler mouth, the valve rod of sampling under pressure promoted elastomeric switch sealing sampler mouth; When the pressure of sampler mouth was higher than the sampling thief mouth, elastomeric switch resetted and pushes the sampling valve rod open, and the air pressure that thief hole exceeds is discharged from venting port; When the pressure of sampler mouth was lower than sampled pressure, the sampling valve rod sealed thief hole once more, and so reciprocal operation can realize electrolyzer inner cathode and the anode pressure balance between barrier film.
Honeycomb structure electrode of the present utility model except being convenient to flowing of electrolytic solution and electrolysis bubbing, also can reduce interelectrode contact resistance.And can guarantee to realize self-poise from the inside and outside pressure reduction that causes of electrolyzer by the pressure balance device.Pressure balance device and honeycomb structure electrode use in oxyhydrogen generator simultaneously, can improve liberation of hydrogen greatly, analyse oxygen pressure, and assurance asbestos film is worked under no pressure reduction condition, realizes hydro-electrolytic hydroxide generator complete machine trouble-free service under middle and high pressure.This producer can arbitrarily move and greatly make things convenient for the needs of all types of user to hydrogen, oxygen, has extensive market prospects.
