⑶ shown in Fig. 6-7; Make a dividing plate 12 with stainless material; Make device form two cavitys up and down, dividing plate one end has shirt rim 20, the other end is plane, is shaped on the IT that is connected with the reaction chamber outside screw on the internal diameter of shirt rim; Be shaped on the end face of said shirt rim outer bulkhead do not limit quantity the hole as liquid pore 19, the liquid pore is as the passage of the hydrogen that injects water and generation;
⑷ shown in Fig. 2-3; Make a housing 10 with stainless steel, housing is a round barrel shape, near the bucket bottom water port 2 is arranged on the housing wall; Shell upper has the diameter groove identical with the dividing plate diameter, can directly be placed on this groove part after dividing plate and reaction chamber assembling are accomplished; The housing external wall of upper portion is shaped on outside screw;
⑸ shown in Fig. 4-5; The loam cake 14 that is made into one with stainless steel; The top of loam cake is that arcuation, bottom are the cylinder tubbiness, and the top of loam cake is shaped on a water filling port 15 and a hydrogen opening 16, and the lower end inwall of loam cake is processed with IT that connects housing and the retaining platform of pushing down dividing plate;
The assembling of reaction chamber
⑹ as shown in Figure 1, in drying room, the micro-crystalline ceramic film among the step ⑴ is bonded in the largest circumference place on the reaction chamber bottom surface of step ⑵ preparation with silica gel 3, and hunts leak, and has the place of leakage to bond again; On the micro-crystalline ceramic film, load dielectric film 5, lithium ingot 6, push pedal 7 and the spring 8 of thickness 0.2mm～1mm from bottom to top successively; Said colloid dielectric film is the absorption 1M LiPF measure-alike with the micro-crystalline ceramic film
6The PVDF-HFD base polymer electrolyte of EC/DEC electrolytic solution, the interface impedance as transition layer reduction metallic lithium and micro-crystalline ceramic film quickens the reaction of metallic lithium and water, improves the generating rate of hydrogen; The lithium ingot is the smooth cylindrical pure lithiums in two ends; Its section area equates with micro-crystalline ceramic film useful area; The useful area of micro-crystalline ceramic film is that its real area deducts and the reaction chamber bottom adhesive area of part together, to improve the utilization ratio of micro-crystalline ceramic membrane area; Push pedal is the diameter stainless steel substrates identical with the reaction chamber internal diameter, and effect is to make the impellent of spring be evenly distributed on the lithium ingot surface, guarantees that the contact surface impedance of lithium ingot and dielectric film, dielectric film and micro-crystalline ceramic film is even, lithium ingot reaction surface homogeneous reaction; Spring is the stainless steel spring of length greater than the reaction chamber height, and its effect is to continue to contact with dielectric film along with the consumption of lithium ingot promotes the lithium ingot, prevents the disengaging of lithium ingot and dielectric film, causes reaction terminating; Dividing plate shirt rim inner bottom part place with fill up the silica gel sheet as reaction chamber pad 11 after, dividing plate and reaction chamber thread seal are loaded into one, the assembling of completion reaction chamber;
The assembling of single unit system
Dividing plate is placed on the groove 22 of housing; Place one deck silica gel sheet identical on the dividing plate as dividing plate gasket seal 13 with the housing external diameter; The loam cake thread seal is installed on the housing; Dividing plate is separated into upper chamber 23 and lower chambers 24 with single unit system inside; Inner for the access to plant that prevents impurity and dust, stop up water port, stop up water filling port, stop up hydrogen opening with draining stifled 1 with going out hydrogen stifled 18 with water filling stifled 17, promptly assemble out the reaction of preparation lithium water and use device;
Lithium water reaction hydrogen manufacturing:
⑺ during hydrogen manufacturing, it is stifled and go out that hydrogen is stifled to be taken off with the water filling of device that back lithium water reaction is accomplished in step ⑹ assembling, seals the injection pure water at water filling port; Pure water flow into lower chambers from the liquid pore of upper chamber on dividing plate; The water level of lower chambers is higher than the reaction chamber bottom and is lower than dividing plate is standard, and water arrives the micro-crystalline ceramic film through the reacting hole of reaction chamber bottom, because the micro-crystalline ceramic film is to electronic isolation to lithium ion conducting; And can not pass through water molecules, the inner lithium ingot of the reaction chamber Li-e → Li that reacts
+, Li
+It is outside to arrive reaction chamber through dielectric film and micro-crystalline ceramic film, and the part that outer wall contacts with water generates hydrogen, flows to upper cavity from hydrogen through the liquid pore of dividing plate, through being connected to the hydrogen opening releasing hydrogen gas on the hydrogen storage equipment; Directly link to each other like hydrogen opening, use as one with the fuel cell hydrogen inlet; After using end, put clean lithium water reaction, stop to produce hydrogen with the inner water of device; Stifled with draining again, water filling is blocked up, is gone out stifled respectively water port, water filling port and hydrogen opening sealing thread connections of hydrogen and blocks up the obstruction pipeline, to prevent the entering of impurity and dust.
During long-time the use, because the effect of reaction chamber contained spring push pedal, the lithium ingot consumes a part of afterreaction face and also contact with ionogen always, and assurance lithium ingot can complete reaction; After inner lithium ingot consumption fully, can disassemble this steam iron generator, change dielectric film, re-assembly behind the filling lithium ingot, can continue afterwards to come into operation; The process of changing needs in dry atmosphere, to carry out.
The colloidal electrolyte film of filling among the cancellation embodiment 1; At micro-crystalline ceramic film surface magnetic control sputtering one layer thickness at the LIPON film of 0.5 μ m～2 μ m as the transition dielectric film; There is the micro-crystalline ceramic film of LIPON film to use silica gel to be bonded in the reaction chamber bottom sputter; The LIPON rete is hunted leak up afterwards, has the situation of leakage to need bonding again; All the other are identical with embodiment 1.
Principle of work of the present invention: the micro-crystalline ceramic film is a kind of to the disk type hard films of lithium ion conducting to electronic isolation; And can not pass through water molecules; The water level that injects be higher than reaction chamber the bottom, be lower than the height of dividing plate, the inner lithium ingot of the reaction chamber Li-e → Li that reacts
+, Li
+It is outside to arrive reaction chamber through dielectric film and micro-crystalline ceramic film; Simultaneously because inner lithium ingot, push pedal, spring, dividing plate and the reaction chamber housing of reaction chamber all is that the conductivity good metal is as conductor; Electronics arrives the reaction chamber housing through reaction chamber interior metal loop, with the hydrogen ion of the pure water that the injects 2H that reacts
++ e → H
2After the water emptying, because of the reaction chamber outside does not have H
+Participate in reaction, entire reaction course stops.
The above is merely preferred implementation of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some distortion and improvement, this also should belong to the protection domain of the utility model.
