Embodiment
In the prior art, when utilizing intermittent energy source as power supply source water electrolysis hydrogen production/oxygen, after the capable voltage stabilizing of unsettled electric energy, directly supply with electrolyzer and carry out brine electrolysis, the two ends of electrolyzer can produce hydrogen and oxygen respectively.Because the electric energy that intermittent energy source produces has unstable; So when the electric energy that produces hour; Maybe be because too much as the electrolyzer quantity of load; Make electrolyzer be in the more a spot of hydrogen/oxygen of work generation under the very low electric current, electrolyzer is not in the ideal operation state though intermittent energy source is fully used; Perhaps, the electric energy that produces when intermittent energy source has surpassed the required electric energy of fixed qty electrolyzer works better more, and additional electric energy will be wasted so, and this moment, intermittent energy source was not fully utilized, and electrolyzer is not in the ideal operation state.A kind of method of utilizing the intermittent energy source brine electrolysis provided by the present invention to be implemented in the brine electrolysis process, makes full use of intermittent energy source, guarantees that simultaneously electrolyzer is in the purpose of ideal operation state.
At first a kind of method of intermittent energy source brine electrolysis of utilizing provided by the present invention is introduced below, this method comprises:
The electric energy that intermittent energy source produced is carried out voltage stabilizing to be handled;
Detect voltage stabilizing and handle the voltage of back intermittent energy source electric energy, obtain voltage of voltage regulation;

To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
A kind of method of utilizing the intermittent energy source brine electrolysis provided by the present invention, as depicted in figs. 1 and 2, comprising:
S101 carries out voltage stabilizing to the electric energy that intermittent energy source produced and handles;
Because when utilizing intermittent energy source such as sun power, tidal energy, wind energy to generate electricity; The electric energy that is produced has unstable; So, handle so need carry out voltage stabilizing to the electric energy that intermittent energy source produced in order to guarantee in the brine electrolysis process that electrolyzer is worked under stable voltage.The mode that voltage stabilizing is handled can for: electric energy that intermittent energy source produced through stable-pressure device, is handled to carry out voltage stabilizing.The effect of said stable-pressure device: the unstable voltage that intermittent energy source produced is adjusted into rated output voltage.Those skilled in the art it is understandable that said stable-pressure device can adopt potentiostat, but are not limited to potentiostat.
S102 detects the voltage that back intermittent energy source electric energy is handled in voltage stabilizing, obtains voltage of voltage regulation;
In the present embodiment, the electrolyzer that is connected in the current circuit is called current electrolyzer.In the brine electrolysis process, said current electrolyzer is in running order.
Need to prove that current electrolyzer can be for one or more; When current electrolyzer was one, the two ends that directly are parallel to the stable-pressure device that is used for the voltage stabilizing processing got final product; When current electrolyzer is a plurality of, be parallelly connected between the electrolyzer, and parallelly connected with the stable-pressure device that is used for the voltage stabilizing processing.
When the electric energy after voltage stabilizing is handled carries out voltage detecting; Owing to be parallel connection between the current electrolyzer; And be connected in parallel on the stable-pressure device that is used for voltage stabilizing and handles (for example: two ends potentiostat), so detect the voltage that the voltage of electric energy after the voltage stabilizing just detects current electrolyzer two ends.
S103 compares said voltage of voltage regulation and the required voltage rating of current cell operation, if said voltage of voltage regulation greater than said voltage rating, is then carried out S104; If said voltage of voltage regulation less than said voltage rating, is then carried out S105; If said voltage of voltage regulation value in the said range of nominal tension, is carried out S106;
In the brine electrolysis process, when electrolyzer is worked, not only have the life-span that higher electrolytic efficiency can not influence electrolyzer simultaneously in certain voltage range, at this moment, electrolyzer is in the ideal operation state, and this voltage range is the voltage rating of electrolyzer.When WV during greater than the voltage rating of electrolyzer, electrolyzer has higher electrolytic efficiency, but can influence the life-span of electrolyzer; When WV during less than the voltage rating of electrolyzer, the electrolytic efficiency of electrolyzer is relatively low.
Said voltage rating is relevant with the electrolyzer self characteristics.Wherein, have different ionogen, electrode, electrolyser construction, the pairing voltage rating of the electrolyzer of other critical materials or working temperature is different.In order to reach good electrolysis effectiveness, in the present embodiment, said current electrolyzer can be the solid polymer electrolyte electrolyzer.
Need to prove that the voltage of voltage regulation that obtains when detection can show that current electrolyzer has made full use of intermittent energy source during less than the rated output voltage of stable-pressure device.Therefore, in order to confirm that electric energy that intermittent energy source is produced is fully utilized and guarantee that current electrolyzer can work that in the range of nominal tension rated output voltage of said stable-pressure device should be slightly larger than the voltage rating of electrolyzer.Wherein, said rated output voltage exceeds the concrete numerical value of said voltage rating, decides according to practical situation.
After electric energy that intermittent energy source produced is handled through voltage stabilizing, detect the voltage of voltage regulation that obtains and whether be the standard adjusting current electrolyzer of judging whether in the range of nominal tension.This be because:
The voltage of voltage regulation (that is: the WV of electrolyzer) that obtains when detection is in the range of nominal tension time, and current electrolyzer has made full use of intermittent energy source, and the electrolytic efficiency of current electrolyzer is higher, produces more hydrogen/oxygen, is in the ideal operation state;
The voltage of voltage regulation (that is: the WV at electrolyzer two ends) that obtains when detection is when equaling the rated output voltage of stable-pressure device, and this moment, intermittent energy source was not fully utilized, and electrolyzer is not in the ideal operation state simultaneously; It is understandable that; When the output rating of intermittent energy source just equates with the power of electrolyzer, also the rated output voltage that voltage of voltage regulation equals stable-pressure device can appear, and this moment, intermittent energy source was fully utilized; But in practical application, the probability that this situation occurs is minimum.
The voltage of voltage regulation (that is: the WV of electrolyzer) that obtains when detection during less than said rated output voltage, explain that current electrolyzer has made full use of the electric energy that intermittent energy source produces, but current electrolyzer is not in the ideal operation state greater than voltage rating;
The voltage of voltage regulation (that is: the WV of electrolyzer) that obtains when detection is when being slightly less than voltage rating; Current electrolyzer is worked under very little electric current; Though this moment, current electrolyzer can make full use of the electric energy that intermittent energy source produces, electrolyzer is not in the ideal operation state;
The voltage of voltage regulation (that is: the WV of electrolyzer) that obtains when detection is very little the voltage rating relatively, this moment excessive electrolyzer as load, make voltage pole low, cause current electrolyzer to start, intermittent energy source can not be fully used.
For example:
Required voltage rating is U1-U2 when supposing cell operation, and its corresponding rated output is W1-W2; The rated output voltage of the stable-pressure device that utilized of hypothesis is the U3 a little more than U2 simultaneously, and the power that electrolyzer is corresponding under said rated output voltage is W3 and W3>W2; Set n above-mentioned electrolyzer parallel connection:
When (1) voltage after detecting the intermittent energy source voltage stabilizing was U3, the operating power W of current electrolyzer equaled nW3, and at this moment, intermittent energy source is not fully utilized, and current electrolyzer is not in the ideal operation state;
When (2) voltage after detecting the intermittent energy source voltage stabilizing was U2-U3, the operating power W of current electrolyzer was: nW2<W<nW3, and at this moment, intermittent energy source is fully used, but current electrolyzer is not in the ideal operation state;
When (3) voltage after detecting the intermittent energy source voltage stabilizing was U1-U2, the operating power W of current electrolyzer was: nW1<W<nW2, and at this moment, intermittent energy source is fully used, and current electrolyzer is in the ideal operation state;
When (4) voltage after detecting the intermittent energy source voltage stabilizing is slightly less than U1; Current electrolyzer is worked under less current, at this moment, 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 the ideal operation state;
When (5) voltage after detecting the intermittent energy source voltage stabilizing was very little with respect to U1, caused intermittent energy source can not be utilized because the electrolyzer of excessive number can't start this moment.
From the above, through 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 in order to guarantee that intermittent energy source makes full use of and electrolyzer is in the ideal operation state, the voltage of voltage regulation that obtains when detection is carried out S104 during greater than said voltage rating, current electrolyzer is carried out step-down handle; The voltage of voltage regulation that obtains when detection is carried out S105 during less than said voltage rating, to the electrolyzer processing of boosting; And when detecting the voltage of voltage regulation obtain in the range of nominal tension time, needn't boost or step-down, directly carry out S106.
S104 behind the identical electrolyzer of said current electrolyzer parallel connection voltage rating, carries out brine electrolysis;
When said voltage of voltage regulation equaled the rated output voltage of said stable-pressure device, the intermittence energy was underutilized, and current electrolyzer is not in the ideal operation state; And but when said voltage of voltage regulation during greater than said voltage rating less than the rated output voltage of stable-pressure device, though the electric energy that intermittent energy source produced is fully used, current electrolyzer is not in the ideal operation state.
For above-mentioned two kinds of situation; Make current electrolyzer in desirable working order when guaranteeing to make full use of intermittent energy source; Can be through carrying out step-down for the mode of the subsequent use electrolyzer of current electrolyzer parallel connection; Make current electrolyzer in voltage rating work, so not only can make full use of intermittent energy source, guarantee that simultaneously current electrolyzer is in the ideal operation state.
Need to prove, in the brine electrolysis process, need preset a plurality of voltage ratings subsequent use electrolyzer identical with current electrolyzer voltage rating.In the time need carrying out step-down, then select electrolyzer suitable in the subsequent use electrolyzer to carry out parallel connection through the mode of parallelly connected electrolyzer.
It is understandable that the rated output of subsequent use electrolyzer is different with 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 subsequent use electrolyzer 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 peak of K is provided with according to the peak power of the output of intermittent energy source size, makes the peak power of the peak power sum of all electrolyzers under voltage rating greater than intermittent energy source output.
In the present embodiment, the identical electrolyzer of said current electrolyzer parallel connection voltage rating, as shown in Figure 3, can be specially:
S104a, the subsequent use electrolyzer that will have maximum rated power carries out parallelly connected with current electrolyzer;
S104b, the voltage of the intermittent energy source electric energy after the detection voltage stabilizing is handled obtains reference voltage;
S104c compares said reference voltage and said voltage rating, if said reference voltage greater than said voltage rating, is then carried out S104a; If said reference voltage less than said voltage rating, is then carried out S104d; If said reference voltage in the said range of nominal tension, is then carried out S104e;
S104d breaks off the subsequent use electrolyzer of current parallel connection, and will less than subsequent use electrolyzer in the subsequent use electrolyzer of its rated output and current electrolyzer with maximum rated power carry out parallelly connected after, carry out S104b;
S104e, parallelly connected processing finishes.
In the above-mentioned parallel way in the present embodiment, carry out parallelly connected with current electrolyzer successively from big to small according to subsequent use electrolyzer rated output.The reference voltage (that is: the voltage at electrolyzer two ends) that obtains when detection is during still greater than said voltage rating; Then can continue to carry out parallelly connected with current electrolyzer the subsequent use electrolyzer of remaining maximum rated power; Continue to judge then and detect the reference voltage that obtains and the magnitude relationship of said voltage rating this moment, repeat corresponding processing according to magnitude relationship; The reference voltage that obtains when detection is less than said voltage rating; Then can break off the subsequent use electrolyzer parallelly connected with current electrolyzer; Reselecting other subsequent use electrolyzers carries out parallelly connected with current electrolyzer; When reselecting, still select according to subsequent use electrolyzer rated output order from big to small.
Need to prove; When the subsequent use electrolyzer of a certain rated output with after current electrolyzer is parallelly connected; The reference voltage that detection obtains is less than said voltage rating, and then when reselecting subsequent use electrolyzer, other subsequent use electrolyzers identical with the subsequent use electrolyzer rated output of said parallel connection are not in range of choice; But select the maximum electrolyzer of rated output outside the identical subsequent use electrolyzer of said a plurality of rated output to carry out parallel connection, carry out follow-up detection, judgement then.
S105, reduce the quantity of said current electrolyzer after, carry out brine electrolysis;
When said voltage of voltage regulation is slightly less than the voltage rating of current electrolyzer, flow down work in small electric, though intermittent energy source is fully used, current electrolyzer is not in the ideal operation state; And when said voltage of voltage regulation with respect to the voltage rating of current electrolyzer hour, too much electrolyzer makes that the voltage pole at electrolyzer two ends is low, makes current electrolyzer to start, intermittent energy source can't obtain utilizing.
For above-mentioned two kinds of situation; Current electrolyzer is in desirable working order when guaranteeing to make full use of intermittent energy source; The mode of quantity that can be through 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 and be in the ideal operation state.
In the present embodiment, the quantity of the said current electrolyzer of said minimizing, as shown in Figure 4, can be specially:
S105a breaks off the electrolyzer that has maximum rated power in the said current electrolyzer;
S105b, the voltage of the intermittent energy source electric energy after the detection voltage stabilizing is handled obtains reference voltage;
S105c compares said reference voltage and said voltage rating, if said reference voltage less than said voltage rating, is then carried out S105a; If said reference voltage greater than said voltage rating, is then carried out S105d, if said reference voltage in the said range of nominal tension, is then carried out S105e;
S105d, the electrolyzer of parallelly connected current disconnection, and disconnection is again carried out S105b less than the electrolyzer with maximum rated power in the current electrolyzer of its rated output;
S105e breaks off processing and finishes.
In reducing the process of current electrolyzer quantity, according to rated output order from big to small in the current electrolyzer, break off electrolyzer and carry out judgment processing, after breaking off electrolyzer, detect the reference voltage that obtains in the range of nominal tension till.
S106 utilizes said current electrolyzer to carry out brine electrolysis.
When said voltage of voltage regulation is in the said range of nominal tension, directly utilizes the electrolyzer of current existence to carry out water electrolysis hydrogen production/oxygen and get final product.
In the scheme provided by the present invention, when utilizing intermittent energy source to carry out brine electrolysis for the electrolyzer power supply, after the electric energy voltage stabilizing processing that intermittent energy source produced, detect the voltage of intermittent energy source electric energy, determine voltage of voltage regulation as power supply; Judge that then whether said voltage of voltage regulation in the required range of nominal tension, according to judged result, is adjusted current electrolyzer, carries out follow-up brine electrolysis then when the electrolyzer works better.In this programme; According to the fluctuation size of intermittent energy source electric energy voltage of voltage regulation after the voltage stabilizing, confirm the electrolyzer of proper amt, make electrolyzer in the range of nominal tension, work; Make full use of intermittent energy source with this, and guarantee that simultaneously electrolyzer is in the ideal operation state.
