Background technology
The renewable energy power generation such as wind energy, solar energy is utilized to be the topmost mode that the mankind utilize generation of electricity by new energy in the future.Because wind energy, solar power generation process affect by natural cause such as weather etc., have randomness, discontinuous feature, the electric energy being difficult to keep stable exports, and the apparatus for storing electrical energy of needs and certain scale matches, form complete electric power system, ensure continual and steady electric power supply.Therefore, develop high, that storage volume is large, economic performance the is good energy-storage system of electric energy conversion efficiency and become the key problem in technology utilizing generation of electricity by new energy.With various forms of energy storage technology, such as retaining energy-accumulating power station, high speed flywheel mechanical energy storage, superconducting energy storage etc. are compared, the features such as it is high that electrochemical energy storage has energy conversion efficiency, and mobility is strong, have unique advantage in all kinds of energy storage technology.In various electrochemical energy storage technology, flow battery system has Large Copacity electrical power storage and Efficient Conversion function, and long service life, environmental protection, safety feature, be easy to match with wind energy, solar power generation, significantly can reduce equipment manufacturing cost, for generation of electricity by new energy provides technique guarantee.For network system energy storage, be suitable for the uninterrupted power supply use of medium-scale industrial enterprise, hotel, government department, effectively can improve grid supply quality, complete " peak load shifting " effect of electrical network.
All-vanadium flow battery (Vanadium Redox Battery, VRB) be a kind of mechanism of new electrochemical power sources, the storage and release that realize electric energy is mutually transformed by the vanadium ion of different valence state, use v element of the same race to form battery system, avoid variety classes active material between positive and negative half-cell from principle and interpenetrate the cross pollution of generation.(Fig. 1) use dissolve in the electrolytic solution different valence state vanadium ion as anode and negative electrode active material, anode electrolyte and electrolyte liquid separately store, avoid battery storage process self-discharge phenomenon from principle, be suitable for the application of extensive thermal energy storage process.Anode electrolyte storage tank B and electrolyte liquid storage tank A is all-vanadium flow battery by magnetic drive pump D positive pole E and negative pole E provides electrolyte, and positive pole E and negative pole E ' is separated by amberplex G, for power source loads C powers.When the power of wind energy, device of solar generating exceedes rated output power, by the charging to flow battery, be that chemical energy is stored in the ion pair of different valence state by electric energy conversion; When Blast Furnace Top Gas Recovery Turbine Unit (TRT) can not meet rated output power, flow battery starts electric discharge, is electric energy the chemical energy stored, and ensures stable electrical power stage.Because flow battery is for the significance of the renewable energy power generation such as wind energy, solar energy process, obtain common concern at home and abroad as key technology.
All-vanadium flow battery charge/discharge running, will there is following redox reaction in electrode.
Positive pole reacts:
Negative reaction:
Because anode electrolyte and electrolyte liquid are in oxidizability valence state and reproducibility valence state respectively, it is no matter the charge/discharge running in pile inside, or electrolyte course of conveying, need to keep anode electrolyte and electrolyte liquid not to mix, otherwise between the vanadium ion of different valence state, exchang electron produces self-discharge phenomenon each other, has a strong impact on battery efficiency.Normal conditions, flow battery system comprises pile district (comprising single battery heap or multiple pile serial or parallel connection), electrolysis liquid zone (comprising two kinds of electrolyte storage tank, transfer pipeline, delivery pumps etc.), if there is a large amount of leakage situation in these two regions, find out by liquid level gauge, but leak if a small amount of or run for a long time to leak and will be difficult to detection, even if find a small amount of leakage in above-mentioned two districts or run leakage, appropriate remedial measure is timely taked to be very important, in order to avoid produce the accidents such as large leakage.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and the fast automatic warning device that a kind of flow battery system safely and effectively leaks is provided.
Object of the present invention can be achieved through the following technical solutions: the fast automatic warning device that a kind of flow battery system leaks, comprise electrolysis liquid zone, pile district, it is characterized in that, also comprise automatic control system, this automatic control system comprises protective fence and is arranged on the current probe bottom protective fence, the alarm be connected with current probe, described electrolysis liquid zone and pile district are placed in protective fence; When electrolysis liquid zone or pile district leak, the electrolyte leaked out makes current probe two pole conducting, causes alarm equipment alarm.
Described protective fence comprises a ramped bottom surface, and described current probe is arranged on the minimum side of ramped bottom surface physical features.
Described protective fence inner surface adopts ceramic paster or carries out anti-acid treatment, and described acid-proof is treated to surface-coated epoxy resin within it.
Described current probe comprises at least two metal guide rods, current acquisition wire, and multiple metal guide rod is disposed on bottom protective fence, and is communicated with by current acquisition wire, applies the voltage of a 12 ~ 24V simultaneously, forms a current circuit; When electrolyte leakage is by Metallic rod conducting, generation current in described current circuit, triggered alarm is reported to the police.
The side that bottom described protective fence, physical features is minimum is provided with electrolyte afflux ditch, metal guide rod is arranged in this electrolyte afflux ditch, when electrolyte does not leak, be open circuit, not generation current between metal guide rod, during electrolyte leakage, because electrolyte is made up of vanadic sulfate, sulfuric acid solution, there is larger conductivity, using the metal guide rod conducting as two poles, current circuit generation current.
Described multiple metal guide rods arrange one at interval of 0.5 ~ 1m.
Compared with prior art, the present invention has the following advantages: go all to arrange protective fence in pile district and electrolyte, it is the low inclined-plane with inclination angle of higher end bottom protective fence, the electrolyte of leakage can be focused on the minimum side of bottom surface physical features, in this side, multiple metal guide rod is set, and connect guide rod formation current circuit by wire, when there is no leak, electric conductor conducting is not had between metal guide rod, therefore open circuit, when electrolyte leakage, because the conductance of electrolyte is at 100 ~ 300ms/cm, can by conducting between metal guide rod, form the current circuit of a conducting, thus initiation alarm equipment alarm, therefore, can find to leak in the very first time, and timely remedial measure can be taked, in case be further developed into the major break downs such as large leakage.
