A liquid path device is connected through a water charging pump with a non-return valve, an alkali tank, a circulating pump, a flow switch, a filter and an electrolytic bath; the hydrogen path structure of a gas path device is composed of a hydrogen condenser connected with a differential pressure running regulator, a differential pressure shutting regulator, a back pressure valve, a safety valve, a hydrogen pressure gauge, a hydrogen pressure sensor, an oxygen-in-hydrogen detector and a hydrogen purging valve; an oxygen path structure is composed of an oxygen condenser connected with a differential pressure running regulator, a differential pressure shutting regulator, an oxygen pressure gauge, an oxygen pressure sensor, a hydrogen-in-oxygen detector, and an oxygen delivery valve. The purity of hydrogen production is 99.99 %, and water content is less than or equal to 1.7 g.m<3>H2.
Description
The present invention relates to a kind of efficient electrolysis water hydrogen generator that high-purity hydrogen is provided.
Using maximum water electrolysis hydrogen production devices in industrial production is to separate the hydrogen-oxygen 2 air chambers with woven asbesto as barrier film, and it requires the operating pressure of hydrogen-oxygen 2 air chambers to balance each other, and pressure reduction is controlled within the hundreds of millimeter water column.But because the porosity of woven asbesto is bigger, the gas in the 2 air chambers is string leakage mutually easily, causes the gaseous mass that is produced poor, and hydrogen purity has only 98%.Although some device for producing hydrogen adopts advanced pressure reduction control mode, hydrogen purity brings up to 99.7%, but still does not satisfy the requirement that some users use high-purity hydrogen.Owing to be subjected to the extremely not influence of anti-rush of current of asbestos film thickness, its running current density has only 1500-2100A/m simultaneously
2, not only electrolytic efficiency is low, bulky, but also brings the inefficient shortcoming of main and auxiliaries
Advanced at present technology (JAPPLELeetrochem18 (1988) 1-4) is to adopt ion-exchange membrane or special membrane, and the inconsistent two kinds of perforation plates in employing aperture are electrode, to form zero pole span, can partly solve the problem of spacing, reduced energy consumption to a certain extent.But this device needs strict control condition, inconvenient operation, and this device does not still solve the electrolytic problem of common conduit simultaneously.Therefore, the gas purity that uses this technology and provided is not high.In addition, this device is difficult in the industrial production and adopts also because of the cost height.
The circulation of elecrolyte mode of the water electrolysis hydrogen production device employing in the industrial production is two circulations now, and promptly all there are circulation of elecrolyte in hydrogen, oxygen room, and the liquid-way system more complicated makes troubles for control and maintenance.And all do not have the flow of electrolyte controlling elements, and can not monitor the flow of electrolytic solution at any time, during not enough or zero flow, bring following shortcoming: the heat that electrolysis produced can not in time be taken away by electrolytic solution, easily causes electrolyzer temperature too high when flow of electrolyte; The too high bath voltage that makes of the concentration of electrolyte of electrode surface raises, and electrolytic efficiency descends simultaneously; Aspect pressure-controlling, pressure balance type water electrolysis hydrogen production device adopts pneumatic or electric membrane valve mostly, the complicated cost height of control circuit, failure rate height.
The objective of the invention is to overcome above technical deficiency, provide a kind of self-control strong efficient electrolysis water hydrogen generator, compare, have the following advantages with applied hydrogen production plant by water electrolysis in the present industrial production:
1, purity height: can produce high-purity hydrogen (gas purity 99.99%);
2, water content is low: water content≤1.7g/m
3H
2
3, simple in structure: promptly single chamber circulation of elecrolyte;
4, safe: the high gas barrier property of microporous membrane has determined the security of device;
5, volume is little, in light weight: high current density is little, the lightweight effective assurance of this device volume.
For achieving the above object, electrolyzer in the device of liquid of the present invention road selects for use microporous membrane (mean pore size 50-100nm) to make the barrier film of air chamber, fit tightly two perforation plates as main electrode in the microporous membrane both sides, perforation plate and as adding thoroughly between the division plate of supporting electrode the liquid elastic conduction supports the hard supporting structure of formation.Improve traditional water common pipe of electrolytic bath structure simultaneously, make common conduit inner bushing ring and subchannel internal lining pipe or make frame with insulating material with shared duct with insulating material, constitute the common conduit and the subchannel of electrical isolation, like this can be between 2 air chambers at steady operation under the pressure reduction (0.4MPa), both solve 2 air chambers gas and gone here and there leakage problem mutually, prevented the generation of common conduit electrolysis phenomenon again, gaseous mass is improved.Fitting tightly of main electrode perforation plate and microporous membrane eliminated liquid phase pressure drop and formed zero pole span simultaneously, reduced direct current consumption.
Because the present invention adopts microporous membrane to separate hydrogen, oxygen room, and perforation plate fitted tightly with it, and the hard supporting structure that supports of saturating liquid elastic conduction, make this device can adopt single-cycle circulation of elecrolyte mode, promptly there is circulation of elecrolyte in oxygen room and hydrogen chamber does not have circulation of elecrolyte.Because hydrogen chamber's pressure is higher than oxygen room's pressure, do not see through microporous membrane at oxygen room's round-robin electrolytic solution and arrive hydrogen chamber, simplify the structure and reduced the water content (water content≤1.7g/m of hydrogen of hydrogen
3H

For guaranteeing efficient, stable operation, this device is provided with the flow valve of monitoring flow of electrolyte, come the minimum flow rate of assurance device operation, in flow of electrolyte just often, the float that the electrolytic solution kinetic head makes its inside have magnet floats, under the effect of magnet magnetic force, the contact of dry-reed tube inside disconnects to the outflow rate normal signal; When making flow of electrolyte be lower than minimum flow rate for a certain reason, because distance, magneticaction is less than on the dry-reed tube, and the contact adhesive provides a warning stopping signal.
This device adopts differential pressure regulator to control the pressure difference of hydrogen, two kinds of gases of oxygen, differential pressure regulator is divided into operation differential pressure regulator and shut off differential pressure setter, form by three chambers, top is the control air chamber, the bottom is the output air chamber, intermediate chamber and last lower chamber are isolated by the sealed rubber diaphragm, be provided with a transmission piece and connect lower chamber in intermediate chamber.Oxygen is controlled in the emptying of oxygen, hydrogen and hydrogen pressure is poor by two setters, when hydrogen, when oxygen pressure reduction is lower than set(ting)value, the action of operation differential pressure regulator, the unnecessary oxygen of emptying improves hydrogen, oxygen pressure reduction; When hydrogen, when oxygen pressure reduction is higher than set(ting)value, the action of shut off differential pressure setter, the unnecessary hydrogen of emptying reduces hydrogen, oxygen pressure reduction, thereby reaches the purpose of control pressure reduction, makes the pressure of hydrogen chamber in the electrolyzer be higher than the pressure 0.15-0.2MPa of oxygen room all the time.
