Abstract
The utility model relates to a gas balancing device for producing hydrogen by means of water electrolysis, which comprises a hollow cavity. The hollow cavity is divided into two gas cavities by a thin diaphragm, the two gas cavities include a hydrogen gas cavity and an oxygen gas cavity, the hydrogen gas cavity is provided with a hydrogen outlet and a hydrogen inlet, the oxygen gas cavity is provided with an oxygen outlet and an oxygen inlet, and a convex plate is further arranged on the inner wall of the oxygen gas cavity. A channel of the oxygen outlet penetrates through the convex plate on the inner wall of the oxygen gas cavity. Two half cavities with 'U'-shaped sections are symmetrically bolted by the thin diaphragm to form the hollow cavity. The thin diaphragm is circular in the hollow cavity. An internal gas adjustable balancing device with simple structure is adopted, pressure balancing effect is obvious, pressure balancing speed is increased after equipment is started, and hydrogen yielding time is correspondingly shortened. In addition, running reliability is strengthened, and manufacturing cost of the equipment is lowered.
Description
Technical field
The utility model belongs to chemical technology field, particularly a kind of gaseous equilibrium device that is used for water electrolysis hydrogen producing.
Background technology
In the water electrolysis hydrogen producing process, bigger like the pressure change of electrolyzer, can cause interpenetrating of hydrogen, oxygen, directly influence the purity of hydrogen manufacturing.So in hydrogen production process, must adjust hydrogen-oxygen wall pressure in the groove at any time.The electrolyzer of normal pressure operation generally leans on gas holder, and steam separator, washer are adjusted pressure.But when pressure moves; A pair of pressure regulator must be set in system, and (one is the hydrogen pressure regulator; Another is the oxygen pressure regulator); Gas in the gas holder is carried out pressure adjustment, to guarantee that producing the gaseous tension that the variation with consumption changes at any time because of gas holder is in equilibrium state.
The above-mentioned pressure regulator that in existing installation, adopts mainly contains two kinds: a kind of is float regulator valve, and another kind is a diaphragm valve.Above-mentioned two kinds of pressure regulators are generally the supporting use of paired appearance, and its internal structure is complicated, thereby make the inner hydrogen or oxygen gas equilibrium system of existing hydrogen producer very loaded down with trivial details, have reduced the safety of using, and have also increased the device fabrication cost.
The utility model content
The purpose of the utility model provides a kind of gaseous equilibrium device that is used for water electrolysis hydrogen producing, to solve the problem of using in the existing installation that pressure-regulator complex structure, safety are lower and cost is high.
The technical scheme of the utility model is; A kind of gaseous equilibrium device that is used for water electrolysis hydrogen producing comprises a hollow cavity, is divided into two air cavitys by a diaphragm; Wherein, One is the hydrogen air cavity with hydrogen outlet and hydrogen inlet, and another is the oxygen air cavity with oxygen outlet and oxygen intake, also is provided with a boss on the described oxygen air cavity inwall.
Further, the passage of described oxygen outlet runs through the boss on the said oxygen air cavity inwall.
Further, described hollow cavity is formed by the said diaphragm symmetry of the half chamber process bolt that two sections are " U " font.
Further, said diaphragm is rounded in said hollow cavity.
The utility model substitutes the conventional pressure regulator with the adjustable equilibrator of the simple gas of internal structure, and the pressure equilibrium effect is obvious, make device power-up after pressure equilibrium speed up, corresponding hydrogen output time shortens.This device is greatly simplified equipment pressure Adjustment System, and serviceability is strengthened, and the device fabrication cost reduces.

Embodiment
As shown in Figure 1; The gaseous equilibrium device 20 that is used for water electrolysis hydrogen producing of the utility model; One hollow cavity is divided into two air cavitys by a diaphragm 1, and wherein, one for having the hydrogen air cavity 6 of hydrogen outlet 4 and hydrogen inlet 8; Another is the oxygen air cavity 7 with oxygen outlet 5 and oxygen intake 9, also is provided with a boss 10 on described oxygen air cavity 7 inwalls.The passage of oxygen outlet 5 runs through the boss 10 on oxygen air cavity 7 inwalls.Hollow cavity is " U " font by two sections half chamber forms through said diaphragm 1 symmetrical bolt.Diaphragm 1 is rounded in hollow cavity.
Hydrogen, carrier of oxygen that equipment is produced feed in the adjustable equilibrator 20 of gas after steam separator, cooling, washing condensation; When uneven hydrogen or oxygen gas respectively after gas input port separately gets into air cavity; Because draught head, equilibrator 20 built-in films 1 produce corresponding expansion (moving to pressure air chamber less than normal), adjust spatial volume and pressure size in the air cavity of both sides thereupon; Be equilibrium state until both sides air chamber pressure and film, thereby reach the purpose of balanced gas.Equilibrator 20 profiles that gas is adjustable adopt circular configuration, are formed by left shell 2 and right casing 3 fixing (bolt and sealing) respectively.Enclosure interior has corresponding air cavity respectively, wherein is provided with the middle circular membrane 1 that clamps of boss 10, two shells in the oxygen air cavity 7.The housing both sides are furnished with hydrogen, carrier of oxygen entrance end respectively.
When uneven hydrogen or oxygen gas respectively after gas input port separately gets into air cavity; Because draught head; Equilibrator 20 built-in films 1 produce corresponding expansion (moving to pressure air chamber less than normal); Adjust spatial volume and pressure size in the air cavity of both sides thereupon, be equilibrium state until both sides air chamber pressure and film, thereby reach the purpose of balanced gas.
