Abstract
The invention relates to a double-membrane gas balancing device for hydrogen production by hydrolyzation. The double-membrane gas balancing device is characterized in that: the device comprises a pair of U-shaped housings; a middle ring (7) is disposed between the U-shaped housings; the middle ring (7) is separated from each of the U-shaped housings at two sides with a thin membrane sheet (6); the U-shaped housings and the corresponding thin membrane sheets (6) form two gas chambers, namely a hydrogen chamber with a hydrogen inlet (1) and a hydrogen outlet (4) and an oxygen chamber with an oxygen inlet (12) and an oxygen outlet; a movable membrane sheet (8) is disposed in the space between the two thin membrane sheets (6); and the side surface of the middle ring (7) is provided with at least one gas outlet. Once the thin membrane sheet in one chamber at a side is damaged and gas leaks, the leaked gas is discharged from the gas outlet in the middle ring and is not mixed with the gas in the other chamber, thus avoiding potential safety hazards.
Description
Technical field
The present invention relates to the two film gaseous equilibrium devices of a kind of hydrolytic hydrogen production, belong to hydrolytic hydrogen production technical field.
Background technology
In water electrolysis hydrogen producing process, as larger in the pressure change of electrolyzer, can cause interpenetrating of hydrogen, oxygen, directly affect the purity of hydrogen manufacturing.So hydrogen-oxygen wall pressure in adjustment tank at any time in hydrogen production process.The electrolyzer of normal pressure operation is generally by gas holder, and steam separator, washer are adjusted pressure.But in the time that pressure moves, a pair of pressure regulator must be set in system, and (one is hydrogen pressure regulator, another is oxygen pressure regulator), gas in gas holder is carried out to pressure adjustment, to ensure producing at any time the gaseous tension changing with the variation of consumption in equilibrium state because of gas holder.The above-mentioned pressure regulator adopting in existing installation mainly contains two kinds: a kind of is float regulator valve, and another kind is diaphragm valve.Above-mentioned two kinds of pressure regulators are generally and occur in pairs supporting the use, and its internal structure is more complicated, thereby make existing hydrogen producer internal hydrogen carrier of oxygen equilibrium system very loaded down with trivial details, have reduced the reliability using, and have also increased device fabrication cost.
Therefore, Granted publication number is that the Chinese patent literature of CN102212839B discloses a kind of gaseous equilibrium device for water electrolysis hydrogen producing, and gas pressure balancing equipment has been simplified in the application of this gaseous equilibrium device, has accelerated the balance of gaseous tension.Once damaged but diaphragm occurs, oxyhydrogen is known from experience generation and mixed, and has potential safety hazard, reliability standard is lower.
Summary of the invention
The technical issues that need to address of the present invention are: the gaseous equilibrium device of water electrolysis hydrogen producing of the prior art, once breakage occurs diaphragm, oxyhydrogen is known from experience generation and mixed, and causes potential safety hazard.
The present invention is by the following technical solutions:

The feature of the technical program is: in the basis of prior art " for the gaseous equilibrium device of water electrolysis hydrogen producing ", the improvement that the structure of single diaphragm is carried out.Be provided with intermediate ring, on intermediate ring, set out pore, the both sides of intermediate ring respectively arrange a diaphragm, between two diaphragms, there is certain space, once there is damaged gas leakage in the diaphragm of a side cavity, the gas spilling can be discharged by the production well from intermediate ring, and can not mix with the gas in opposite side cavity, has avoided potential safety hazard.Moving film has two effects, and 2. 1. transmitting thrust is guaranteed to have certain interval between two diaphragms, ensures that production well gives vent to anger unimpeded.
Further, the thickness of described moving film 8 is greater than the aperture of described production well, is less than intermediate ring 7 thickness; Directly through being less than intermediate ring 7 internal diameters.
Further, the side of described intermediate ring 7 is provided with two production wells, two production well conllinear.
Further, described diaphragm 6 is rounded.
Further, described moving film 8 is rounded.
Further, described oxygen chamber has boss, and described oxygen outlet 9 runs through described boss.
Beneficial effect of the present invention is:
1) once breakage occurs diaphragm, hydrogen or oxygen gas also can not mix, and has avoided potential safety hazard.
2) moving film has effectively been brought into play transmitting thrust and has been guaranteed the effect that production well is unimpeded, designs ingenious.
3) simple in structure, reliability is strong, and device manufacturing cost is lower.
4) after device power-up, pressure equilibrium speed is accelerated, corresponding hydrogen output time shorten.
Brief description of the drawings
Fig. 1 is the sectional view of the two film gaseous equilibrium devices of water electrolysis hydrogen producing of the present invention.
Fig. 2 be in Fig. 1 A-A to cross-sectional schematic.
In figure, 1. hydrogen inlet, 2. bolt hole, 3. left outside shell, 4. hydrogen outlet, 5. hydrogen chamber, 6. diaphragm, 7. intermediate ring, 8. moving film, 9. oxygen outlet, 10. right air cavity, 11. right casings.
Embodiment
Below in conjunction with specific embodiments and the drawings, the present invention is further described.
Referring to Fig. 1-2, the two film gaseous equilibrium devices of a kind of water electrolysis hydrogen producing, this device comprises pair of U-shaped case, is respectively left outside shell 3 and right casing 11, be provided with intermediate ring 7 therebetween, described intermediate ring 7 respectively separates by a slice diaphragm 6 with left outside shell 3, the right casing 11 of both sides; Left outside shell 3, right casing 11 form two air cavitys with each self-corresponding diaphragm 6, are respectively the hydrogen chamber with hydrogen inlet 1 and hydrogen outlet 4 and the oxygen chamber with oxygen intake 12 and oxygen outlet; In space between two diaphragms 6, be provided with moving film 8; The side of described intermediate ring 7 is provided with at least one production well.
Referring to Fig. 1, the thickness of described moving film 8 is greater than the aperture of described production well, is less than intermediate ring 7 thickness, directly through being less than intermediate ring 7 internal diameters.So more can guarantee the patency that production well is given vent to anger.
