Embodiment
In prior art, while utilizing intermittent energy source as power supply source water electrolysis hydrogen production/oxygen, by after capable unsettled electric energy voltage stabilizing, directly supply with electrolyzer and carry out brine electrolysis, the two ends of electrolyzer can produce respectively hydrogen and oxygen.The electric energy producing due to intermittent energy source has unstable, so when the electric energy producing hour, may be because the electrolyzer quantity as load is too much, electrolyzer is worked under very low electric current and produce the hydrogen/oxygen of small amount, although intermittent energy source is fully used, electrolyzer is not in ideal operation state; Or the electric energy producing when intermittent energy source when more, has exceeded the required electric energy of the normal work of fixed qty electrolyzer, so extra electric energy will be wasted, and now intermittent energy source is not fully utilized, and electrolyzer is not in ideal operation state.A kind of method of utilizing intermittent energy source brine electrolysis provided by the present invention, to realize in brine electrolysis process, makes full use of intermittent energy source, guarantees the object of electrolyzer in ideal operation state simultaneously.
First a kind of method of utilizing intermittent energy source brine electrolysis provided by the present invention is introduced below, the method comprises:

In scheme provided by the present invention, in the time utilizing intermittent energy source to carry out brine electrolysis as power supply for electrolyzer power supply, after the electric energy voltage stabilizing that intermittent energy source is produced is processed, detect the voltage of intermittent energy source electric energy, determine voltage of voltage regulation; Then judge that whether described voltage of voltage regulation in the required range of nominal tension, according to judged result, is adjusted current electrolyzer in the time that electrolyzer is normally worked, and then carries out follow-up brine electrolysis.In this programme, according to the fluctuation size of intermittent energy source electric energy voltage of voltage regulation after voltage stabilizing, determine the electrolyzer of proper amt, electrolyzer is worked in the range of nominal tension, make full use of intermittent energy source with this, and guarantee that electrolyzer is in ideal operation state simultaneously.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
A kind of method of utilizing intermittent energy source brine electrolysis provided by the present invention, as depicted in figs. 1 and 2, comprising:
S101, the electric energy that intermittent energy source is produced carries out voltage stabilizing processing;
While generating due to intermittent energy source such as utilizing sun power, tidal energy, wind energy, the electric energy producing has unstable, so in order to guarantee that, in brine electrolysis process, electrolyzer is worked under stable voltage, so the electric energy that need to produce intermittent energy source carries out voltage stabilizing processing.The mode of voltage stabilizing processing can be for: the electric energy that intermittent energy source is produced is by stable-pressure device, to carry out voltage stabilizing processing.The effect of described stable-pressure device: the unstable voltage that intermittent energy source is produced is adjusted into rated output voltage.Those skilled in the art are understandable that, described stable-pressure device can adopt potentiostat, but is not limited to potentiostat.
S102, the voltage of rear intermittent energy source electric energy is processed in detection voltage stabilizing, obtains voltage of voltage regulation;
In the present embodiment, the electrolyzer being connected in current circuit is called to current electrolyzer.In brine electrolysis process, described current electrolyzer is in running order.
It should be noted that, current electrolyzer can be one or more; When current electrolyzer is one, be directly parallel to the two ends for the stable-pressure device of voltage stabilizing processing; When current electrolyzer is multiple, between electrolyzer, be in parallel, and with in parallel for the stable-pressure device of voltage stabilizing processing.
In the time that voltage stabilizing electric energy after treatment is carried out to voltage detecting, owing between current electrolyzer being parallel connection, and be connected in parallel on the two ends of the stable-pressure device (for example: potentiostat) for voltage stabilizing processing, so detect the voltage of electric energy after voltage stabilizing and namely detect the voltage at current electrolyzer two ends.
S103, compares described voltage of voltage regulation and the required voltage rating of current cell operation, if described voltage of voltage regulation is greater than described voltage rating, carries out S104; If described voltage of voltage regulation is less than described voltage rating, carry out S105; If described voltage of voltage regulation value, in the described range of nominal tension, is carried out S106;
In brine electrolysis process, when electrolyzer is worked in certain voltage range, not only having higher electrolytic efficiency can not affect the life-span of electrolyzer simultaneously, and now, electrolyzer is in ideal operation state, the voltage rating that this voltage range is electrolyzer.In the time that operating voltage is greater than the voltage rating of electrolyzer, electrolyzer has higher electrolytic efficiency, but can affect the life-span of electrolyzer; In the time that operating voltage is less than the voltage rating of electrolyzer, the electrolytic efficiency of electrolyzer is relatively low.
The characteristic of described voltage rating and electrolyzer self is relevant.Wherein, there is different ionogen, electrode, electrolyser construction, the corresponding voltage rating of electrolyzer of other critical materials or working temperature is different.In order to reach good electrolysis effectiveness, in the present embodiment, described current electrolyzer can be solid polymer electrolyte electrolyzer.
It should be noted that, when the voltage of voltage regulation obtaining when detection is less than the rated output voltage of stable-pressure device, can show that current electrolyzer takes full advantage of intermittent energy source.Therefore,, in order to determine that the electric energy that produces of intermittent energy source is fully utilized and guarantees that current electrolyzer can work in the range of nominal tension, the rated output voltage of described stable-pressure device should be slightly larger than the voltage rating of electrolyzer.Wherein, described rated output voltage exceeds the concrete numerical value of described voltage rating, determines according to practical situation.
When electric energy that intermittent energy source produces is after voltage stabilizing is processed, detect the voltage of voltage regulation that obtains and in the range of nominal tension, be whether the standard need to adjusting current electrolyzer of judging whether.This be because:
The voltage of voltage regulation (that is: the operating voltage of electrolyzer) obtaining when detection is in the range of nominal tension time, current electrolyzer takes full advantage of intermittent energy source, and the electrolytic efficiency of current electrolyzer is higher, produce more hydrogen/oxygen, in ideal operation state;
When the voltage of voltage regulation (that is: the operating voltage at electrolyzer two ends) obtaining when detection equals the rated output voltage of stable-pressure device, now intermittent energy source is not fully utilized, and electrolyzer is not in ideal operation state simultaneously; Be understandable that, in the time that the output rating of intermittent energy source and the power of electrolyzer just equate, also there will be voltage of voltage regulation to equal the rated output voltage of stable-pressure device, now intermittent energy source is fully utilized, but the probability that occurs in actual applications, this situation is minimum.
When the voltage of voltage regulation (that is: the operating voltage of electrolyzer) obtaining when detection is greater than voltage rating and is less than described rated output voltage, illustrate that current electrolyzer takes full advantage of the electric energy that intermittent energy source produces, but current electrolyzer is not in ideal operation state;
When the voltage of voltage regulation (that is: the operating voltage of electrolyzer) obtaining when detection is slightly less than voltage rating, current electrolyzer is worked under very little electric current, although now current electrolyzer can make full use of the electric energy that intermittent energy source produces, electrolyzer is not in ideal operation state;
The voltage of voltage regulation (that is: the operating voltage of electrolyzer) obtaining when detection is relatively very little voltage rating, now excessive electrolyzer is as load, make voltage pole low, cause current electrolyzer to start, intermittent energy source can not be fully used.
For example:
While supposing cell operation, required voltage rating is U1-U2, and its corresponding rated output is W1-W2; The rated output voltage of the stable-pressure device that hypothesis is utilized is simultaneously the U3 a little more than U2, and the power that electrolyzer is corresponding under described rated output voltage is W3 and W3 > W2; Set n above-mentioned electrolyzer parallel connection:
(1) in the time detecting that voltage after intermittent energy source voltage stabilizing is U3, the operating power W of current electrolyzer equals nW3, and now, intermittent energy source is not fully utilized, and current electrolyzer is not in ideal operation state;
(2) in the time detecting that voltage after intermittent energy source voltage stabilizing is U2-U3, the operating power W of current electrolyzer is: nW2 < W < nW3, now, intermittent energy source is fully used, but current electrolyzer is not in ideal operation state;
(3) in the time detecting that voltage after intermittent energy source voltage stabilizing is U1-U2, the operating power W of current electrolyzer is: nW1 < W < nW2, now, intermittent energy source is fully used, and current electrolyzer is in ideal operation state;
(4) in the time detecting that voltage after intermittent energy source voltage stabilizing is slightly less than U1, current electrolyzer is worked under less electric current, now, and the electric energy that too much electrolyzer utilizes intermittent energy source to produce, intermittent energy source is fully used, but electrolyzer is not in ideal operation state;
(5) in the time detecting that voltage after intermittent energy source voltage stabilizing is very little with respect to U1, now, because the electrolyzer of excessive number cannot start, cause intermittent energy source not to be utilized.
From the above, by detecting the fluctuation size of voltage of voltage regulation, can determine whether electric energy that intermittent energy source produces is fully utilized and electrolyzer whether under desirable working order.So, for guarantee that intermittent energy source makes full use of and electrolyzer in ideal operation state, when the voltage of voltage regulation obtaining when detection is greater than described voltage rating, carry out S104, current electrolyzer is carried out to step-down processing; When the voltage of voltage regulation obtaining when detection is less than described voltage rating, carry out S105, to the electrolyzer processing of boosting; And when detecting the voltage of voltage regulation that obtains in the range of nominal tension time, needn't boost or step-down, directly carry out S106.
S104, after the identical electrolyzer of described current electrolyzer voltage rating in parallel, carries out brine electrolysis;
In the time that described voltage of voltage regulation equals the rated output voltage of described stable-pressure device, the intermittence energy is underutilized, and current electrolyzer is not in ideal operation state; And in the time that but described voltage of voltage regulation is greater than described voltage rating is less than the rated output voltage of stable-pressure device, although the electric energy that intermittent energy source produces is fully used, current electrolyzer is not in ideal operation state.
For above-mentioned two situations, make current electrolyzer in desirable working order in order guaranteeing to make full use of intermittent energy source when, can be by carrying out step-down for the mode of current electrolyzer electrolyzer for subsequent use in parallel, make current electrolyzer in voltage rating work, so not only can make full use of intermittent energy source, guarantee that current electrolyzer is in ideal operation state simultaneously.
It should be noted that, in brine electrolysis process, need to preset the electrolyzer for subsequent use that multiple voltage ratings are identical with current electrolyzer voltage rating.In the time need to carrying out step-down by the mode of electrolyzer in parallel, select electrolyzer suitable in electrolyzer for subsequent use to carry out parallel connection.
Be understandable that, the rated output of electrolyzer for subsequent use is different from the rated output of current electrolyzer or identical.For example: suppose that current electrolyzer comprises 1 electrolyzer WA, 1 electrolyzer 2WA, 1 electrolyzer 5WA, the voltage rating of three electrolyzers is U1-U2, the rated output of electrolyzer WA is W1-W2, the rated output of electrolyzer 2WA is 2W1-2W2, and the rated output of electrolyzer 5WA is 5W1-5W2, and the rated output of default electrolyzer for subsequent use can be K (K=1,2,5,10,20,50,100......) times of electrolyzer WA.Be fully used in order to guarantee the electric energy that intermittent energy source produces, wherein the maximum value of K arranges according to the peak power size of the output of intermittent energy source, makes the peak power sum of all electrolyzers under voltage rating be greater than the peak power of intermittent energy source output.
In the present embodiment, the identical electrolyzer of described current electrolyzer voltage rating in parallel, as shown in Figure 3, can be specially:
S104a, carries out in parallel by the electrolyzer for subsequent use with maximum rated power with current electrolyzer;
S104b, the voltage of detection voltage stabilizing intermittent energy source electric energy after treatment, obtains reference voltage;
S104c, compares described reference voltage and described voltage rating, if described reference voltage is greater than described voltage rating, carries out S104a; If described reference voltage is less than described voltage rating, carry out S104d; If described reference voltage, in the described range of nominal tension, is carried out S104e;
S104d, disconnects the electrolyzer for subsequent use of current parallel connection, and by be less than the electrolyzer for subsequent use with maximum rated power in the electrolyzer for subsequent use of its rated output and current electrolyzer carry out in parallel after, carry out S104b;
S104e, parallel processing finishes.
In above-mentioned parallel way in the present embodiment, carry out in parallel with current electrolyzer successively from big to small according to electrolyzer rated output for subsequent use.When the reference voltage (that is: the voltage at electrolyzer two ends) obtaining when detection is still greater than described voltage rating, can continue the electrolyzer for subsequent use of remaining maximum rated power to carry out in parallel with current electrolyzer, then continue the judgement reference voltage that now detection obtains and the magnitude relationship of described voltage rating, repeat corresponding processing according to magnitude relationship; The reference voltage obtaining when detection is less than described voltage rating, can disconnect for subsequent use electrolyzer in parallel with current electrolyzer, reselecting other electrolyzers for subsequent use carries out in parallel with current electrolyzer, in reselecting, still select according to electrolyzer rated output for subsequent use order from big to small.
It should be noted that, after the electrolyzer for subsequent use of a certain rated output is in parallel with current electrolyzer, the reference voltage that detection obtains is less than described voltage rating, in reselecting electrolyzer for subsequent use, other for subsequent use electrolyzers identical with the electrolyzer rated output for subsequent use of described parallel connection are not in range of choice, but select the electrolyzer of the rated output maximum outside electrolyzer for subsequent use that described multiple rated output is identical to carry out parallel connection, then carry out follow-up detection, judgement.
S105, reduces after the quantity of described current electrolyzer, carries out brine electrolysis;
In the time that described voltage of voltage regulation is slightly less than the voltage rating of current electrolyzer, flow down work in small electric, although intermittent energy source is fully used, current electrolyzer is not in ideal operation state; And when described voltage of voltage regulation with respect to the voltage rating of current electrolyzer hour, too much electrolyzer makes the voltage pole at electrolyzer two ends low, and current electrolyzer cannot be started, intermittent energy source cannot be utilized.
For above-mentioned two situations, current electrolyzer is in desirable working order in order guaranteeing to make full use of intermittent energy source when, the mode of quantity that can be by reducing current electrolyzer is boosted, make electrolyzer in voltage rating work, so not only can make full use of current electrolyzer of intermittent energy source while in ideal operation state.
In the present embodiment, the quantity of the described current electrolyzer of described minimizing, as shown in Figure 4, can be specially:
S105a, disconnects the electrolyzer in described current electrolyzer with maximum rated power;
S105b, the voltage of detection voltage stabilizing intermittent energy source electric energy after treatment, obtains reference voltage;
S105c, compares described reference voltage and described voltage rating, if described reference voltage is less than described voltage rating, carries out S105a; If described reference voltage is greater than described voltage rating, carry out S105d, if described reference voltage, in the described range of nominal tension, is carried out S105e;
S105d, the electrolyzer of current disconnection in parallel again, and disconnect the electrolyzer with maximum rated power in the current electrolyzer that is less than its rated output, carry out S105b;
S105e, disconnection process finishes.
Reducing in the process of current electrolyzer quantity, according to rated output order from big to small in current electrolyzer, disconnect electrolyzer and judge processings, until after disconnection electrolyzer, the reference voltage that detection obtains in the range of nominal tension till.
S106, utilizes described current electrolyzer to carry out brine electrolysis.
