Description
Technical field
The utility model relates to a kind of device for producing hydrogen, relates to the device for producing hydrogen of reactive liquid solution specifically.
Background technology
Along with the day of fossil energy is becoming tight and the becoming more and more important of environment protection, cleaning, efficiently is that (Fuel Cell, FC) technology becomes the emerging energy of following Sustainable development, and is subjected to the attention of countries in the world government day by day for the fuel cell of fuel with hydrogen.
Because the hydrogen storage material sodium borohydride has the advantages such as hydrogen purity height of hydrogen-storage amount height, storage security, easy to use, environmental friendliness, generation, recently, sodium borohydride is used for very big interest and the further investigation that hydrogen supply device has caused people as the storage hydrogen carrier.The gordian technique of sodium borohydride hydrogen-feeding system is preparing hydrogen by sodium borohydride hydrolysis catalyzer and preparing hydrogen by sodium borohydride hydrolysis reactor.When adopting fixed bed catalyst such as fixed-bed Raney nickel etc. as the preparing hydrogen by sodium borohydride hydrolysis catalyzer, the concentration of sodium borohydride solution can not be too high, otherwise can make the sodium metaborate that generates in the reaction process on catalyzer, separate out, cover active sites, make catalyzer inactivation gradually, thereby influence the hydrogen supply process.The concentration of sodium borohydride is higher than at 15% o'clock, just has sodium metaborate in the reaction process and separates out, and has limited the raising of sodium borohydride concentration, thereby makes the storage hydrogen rate of total system descend.
And adopt mineral acids such as organic acid such as oxysuccinic acid or hydrochloric acid as the preparing hydrogen by sodium borohydride hydrolysis catalyzer, and can use higher concentration even near the sodium borohydride solution of saturation concentration, the phenomenon of catalyst deactivation can not appear in entire reaction course, the hydrogen supply process is steady.But in order to realize instant hydrogen supply or stop that oxysuccinic acid or other acid need to exist with the form of solution, this has increased the volume of whole system naturally again.Because the sodium borohydride solution hydrolysis is an exothermic process, if reaction back waste liquid directly contacts with sodium borohydride solution, can cause the sodium borohydride solution temperature to raise, just begin to decompose not touching catalyst solution, this can cause hydrogen supply shakiness on the one hand, has potential safety hazard in the hydrogen supply process on the other hand.
The utility model content
The technical problems to be solved in the utility model provides a kind of compact construction, hydrogen supply reactive liquid solution device for producing hydrogen steady, safe in utilization.
For solving the problems of the technologies described above, contriver of the present utility model has carried out a large amount of research and performing creative labour on the basis of existing technology, developed a kind of reactive liquid solution device for producing hydrogen, comprise housing, described enclosure interior is provided with a vertical clapboard, described dividing plate is divided into the fuel cavity and the catalytic chamber of mutual sealing with enclosure interior, is provided with fuel flexible liquid capsule in the described fuel cavity, is provided with elasticity catalytic liquid capsule in the described catalytic chamber; Described fuel flexible liquid capsule and elasticity catalytic liquid capsule upper end are respectively equipped with liquid exit, and described liquid exit is incorporated into the liquid-inlet that the catalytic chamber top is provided with through conduit; Described liquid-inlet is connected with elasticity catalytic liquid capsule catalytic chamber outward, and described catalytic chamber top also is provided with pneumatic outlet.
Described dividing plate is made by lagging material.
Described dividing plate is fixed on the housing.
Described dividing plate is an active clapboard, can move horizontally.
Be equipped with pump on the described conduit.
The volume of described catalytic chamber is greater than the volume of fuel cavity.
When the utility model uses, sodium borohydride solution is injected in the fuel flexible liquid capsule, acidic catalyst solution such as oxysuccinic acid or citric acid are injected in the elasticity catalytic liquid capsule, under the effect of two elastic force of elasticity liquid capsule own, sodium borohydride solution that it is inner and acidic catalyst solution can flow out from outlet, in the catalytic chamber outside conduit flow into elasticity catalytic liquid capsule, hydrolysis reaction taking place therein, generates hydrogen.The gas outlet that the hydrogen that generates is provided with from the catalytic chamber top flows out.The elastic force that elastic sack body itself has can be so that sodium borohydride solution and acidic catalyst solution flow in the catalytic chamber hydrogen supply reacting balance stably.For the flow of better control sodium borohydride solution and acidic catalyst solution or satisfy flow constantly with the requirement of variable power, guarantee that the hydrogen supply process is more controlled, steady, can connect pump on the outside conduit that connects of two elasticity liquid capsules, pump can be micropumps such as piezoelectric ceramic pump, miniature diaphragm pump, micromachine pump, minipump.Because sodium borohydride solution and acidic catalyst solution are the catalytic chamber internal reactions in elasticity catalytic liquid capsule outside, made full use of the space of reactor like this, and along with the solution in the elasticity catalytic liquid capsule flows out gradually, the volume of elasticity catalytic liquid capsule reduces gradually, and the space of leaving reaction solution for increases gradually.Therefore the utility model can take into full account this volume change factor when design, reduces the volume of whole device for producing hydrogen as much as possible, makes the device for producing hydrogen compact and reasonable can be applicable to portable hydrogen supply device.Owing to provide acidic catalyst solution needed volume except needs in the catalytic chamber, also need to provide two kinds of needed volumes of the waste liquid behind the solution reaction, the volume of therefore general design catalytic chamber is greater than the volume of fuel cavity.In addition, dividing plate of the present utility model can also be set to active clapboard, promptly can move horizontally, along with the waste liquid in the catalytic chamber increases gradually, liquid capsule volume in the fuel cavity reduces gradually, and dividing plate can move by occurred level, shifts to fuel cavity one side, thereby the volume of catalytic chamber is increased, utilized overall space more fully.
The hydrolysis reaction of sodium borohydride is thermopositive reaction clearly, therefore sodium borohydride solution and acidic catalyst solution are at the catalytic chamber internal reaction of elasticity catalytic liquid capsule outside, can cause the temperature in the catalytic chamber to raise, because catalytic chamber and fuel cavity are two individual cavity, therefore the temperature in the catalytic chamber raises and can not cause very big influence to the sodium borohydride solution in the fuel cavity, therefore can reduce sodium borohydride solution when not touching acidic catalyst solution, owing to decomposition reaction takes place for the rising of temperature.Dividing plate is made by lagging material, can further reduce the Temperature Influence of the temperature of rising in the catalytic chamber to sodium borohydride solution in the fuel cavity, can prevent better that sodium borohydride solution from decomposition reaction taking place, and has increased the stability and the security of device for producing hydrogen when not touching acidic catalyst solution.Simultaneously, owing to the solubleness of oxysuccinic acid or citric acid etc. all is that rising along with temperature raises, so the temperature that raises in the catalytic chamber, help the dissolving of acid such as oxysuccinic acid or citric acid.
