Description
Technical field:
The utility model relates to a kind of hydrogen safe draining devices, belong to electrolysis with ion-exchange film production field, give birth to for solving
Produce influence of the middle and lower reaches hydrogen users for load fluctuation.
Background technique:
It is that unit electrolytic bath is divided into anode chamber and cathode chamber using cation-exchange membrane, the side for separating electrolytic production
Method.Ion-exchange membrane electrolysis is the technology to grow up on the basis of ion exchange resin (see ion-exchanger).By
The dense common salt aqueous solution of purification enters anode chamber, and sodium ion is mobile to cathode chamber through cation-exchange membrane under electric field action,
The hydroxyl ion generated into the sodium ion of catholyte together with electrolysis water on cathode generates sodium hydroxide, while putting on cathode
Hydrogen out.The hydrogen that electrolysis with ion-exchange film goes out can be delivered to each user after the processing of hydrogen treat process, if because downstream user
There is the case where hydrogen usage saturation, then electrolytic cell is needed to drop electric current, to influence the chlorine balance of downstream user, causes non-faulting
The underproduction of property；If the not underproduction can directly empty excess hydrogen, but it is dangerous relative to the emptying of wet hydrogen to the emptying of dry hydrogen gas
Property is bigger.
Summary of the invention:
The utility model provides a kind of hydrogen safe draining device, and it is negative for producing to can solve downstream hydrogen user fluctuation
The influence of lotus, and the risk of dry hydrogen gas emptying is reduced, guarantee the safety and stability of production.
In order to achieve the above object, the summary of the invention of the utility model is:
A kind of hydrogen safe draining device, including big water seal storage tank, air inlet pipe, exhaust pipe, nitrogen blanketing valve, big water seal water inlet
Pipe, overflow pipe and small water seal storage tank, small water seal water inlet pipe, big water seal drainpipe, small water seal drainage pipe, fire arrester, relevant control
Valve and instrument；The air inlet pipe being equipped with and big water seal water inlet pipe enter in big water seal storage tank, in the exhaust pipe that big water seal storage tank is equipped with
Upper connection nitrogen blanketing valve, while fire arrester is additionally provided on exhaust pipe；Overflow pipe and big water seal drainpipe are arranged in big water seal storage tank
On, discharge outlet enters in small water seal storage tank, and small water seal drainage pipe is arranged on small water seal storage tank, in small water seal storage tank
The discharge of water.
The beneficial effects of the utility model are: may be implemented in electrolysis with ion-exchange film technique, when hydrogen use occurs in downstream user
When the case where amount saturation, the safety dumping to the exess of H2 gas is realized, solve downstream hydrogen user fluctuation for full factory's produce load
Influence, not will cause the underproduction of non-faulting.
Detailed description of the invention:
Fig. 1 is utility model device structural schematic diagram.
In figure: 1. big water seal storage tanks；2. air inlet pipe；3. exhaust pipe；4. big water seal water inlet pipe；5. overflow pipe；6. big water seal
Drainpipe；7. nitrogen blanketing valve；8. small water seal storage tank；9. small water seal drainage pipe；10 fire arresters.
Specific embodiment:
Referring to attached drawing 1, the utility model include big water seal storage tank 1, air inlet pipe 2, exhaust pipe 3, nitrogen charging 7 pipe, big water seal into
Water pipe 4, overflow pipe 5 and small water seal storage tank 8, big water seal drainpipe 6, small water seal drainage pipe 9, fire arrester 10, relevant control valve and
Instrument；Device shape is totally-enclosed cylindrical body, and the air inlet pipe 2 being equipped with and big water seal water inlet pipe 4 enter in big water seal storage tank 1,
Nitrogen blanketing valve 7 is connected on the exhaust pipe 3 that big water seal storage tank 1 is equipped with, while being additionally provided with fire arrester 10 on exhaust pipe 3；5 He of overflow pipe
Big water seal drainpipe 6 is arranged on big water seal storage tank 1, and discharge outlet enters in small water seal storage tank 8, and small water seal drainage pipe 9 is set
It sets on small water seal storage tank 8, the discharge for water in small water seal storage tank 8.
When system is driven, hydrogen gas system manually-operated gate B valve is closed, A valve is opened, and hydrogen walks main line and enters hydrogen treat work
Sequence；Then B valve is suitably opened according to hydrogen station situation, then hydrogen partial enters big water seal storage tank 1 by 2 air inlet pipe, passes through row
Tracheae 3 is emptied.When system operates normally, nitrogen manually-operated gate E valve, C valve are closed, and D valve is opened, and system needs hydrogen to empty
When manually opened E valve, C valve, close D valve, nitrogen purges hydrogen by nitrogen blanketing valve 7 and empties pipeline, close E valve, C valve after qualified,
Open D valve.When system shutdown, operator should open the bypass valve (E valve) of nitrogen automatic valve immediately, avoid because nitrogen is automatic
Valve failure and cause system cannot timely nitrogen charging.
Interlocking explanation:
1, when normal driving, if hydrogen vent line pressure or hydrogen supervisor's line pressure wherein have one to be lower than certain
When one value, pipeline nitrogen charging automatic valve is opened immediately, gives pipeline nitrogen charging.
2, when system shutdown, it is desirable that draining automatic valve is closed, while water automatic valve being added to open, and is added water to hydrogen water seal, is
Nitrogen charging automatic valve of uniting is opened, and pipeline nitrogen charging is given.
The effect of the utility model is: when the case where hydrogen usage saturation occurs in downstream user, realizing to the exess of H2 gas
Safety dumping, solve downstream hydrogen user and fluctuate influence for full factory's produce load, not will cause the underproduction of non-faulting.
By the water seal storage tank being equipped with, makes hydrogen moist discharge after contacting with water, also reduce emptying risk.
