Ore deposit enterprise, hotel, the uninterrupted power source of government department use, and can be effectively improved grid supply quality, complete power grid
" peak load shifting " acts on.
All-vanadium flow battery (Vanadium Redox Battery, VRB) is a kind of mechanism of new electrochemical power sources, passes through different price
The vanadium ion of state mutually converts the storage and release for realizing electric energy, forms battery system using v element of the same race, is kept away from principle
The cross contamination that variety classes active material between positive and negative half-cell interpenetrates generation is exempted from.(Fig. 1) use is dissolved in electrolyte
Middle different valence state vanadium ion is separately stored as anode and negative electrode active material, anode electrolyte and electrolyte liquid, from
Battery storage process self-discharge phenomenon is avoided in principle, is suitable for extensive thermal energy storage process application.Anode electrolyte storage tank B and negative
Pole electrolyte reservoir A provides electrolyte, cathode E and anode E ' by magnetic drive pump D for the cathode E and anode E of all-vanadium flow battery
Separated by amberplex G, powered for power source loads C.When the power of wind energy, device of solar generating exceedes rated output work(
During rate, by the charging to flow battery, convert electrical energy into chemical energy and be stored in the ion pair of different valence state；When power generation fills
Put when cannot meet rated output power, flow battery starts to discharge, and the chemical energy of storage is converted into electric energy, ensures to stablize electricity
Power output.Since flow battery is for the significance of the renewable energy power generation process such as wind energy, solar energy, as crucial skill
Art at home and abroad obtains common concern.
All-vanadium flow battery charge/discharge operational process, will occur following redox reaction on electrode.
Cathode reacts：
Negative reaction：
Since anode electrolyte and electrolyte liquid are respectively at oxidisability valence state and reproducibility valence state, either in pile
Internal charge/discharge operational process, or electrolyte course of conveying is, it is necessary to keep anode electrolyte and electrolyte liquid not to send out
Raw mixing, otherwise exchanges electronics and produces self-discharge phenomenon, seriously affect battery efficiency each other between the vanadium ion of different valence state.Usually
Situation, flow battery system include pile area (including single battery heap or multiple pile serial or parallel connections), electrolysis liquid zone (including
Two kinds of electrolyte storage tanks, transfer pipeline, delivery pumps etc.), the two regions can pass through liquid level gauge in the event of a large amount of leakage situations
Find out, but if a small amount of leakage or long-term race leakage will be difficult to detect, even if finding a small amount of leakage in above-mentioned two areas or running
Leakage, takes appropriate timely remedial measure to be very important, in order to avoid produce the accidents such as big leakage.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of safely and effectively liquid
The fast automatic warning device of galvanic battery system leak.
The purpose of the present invention can be achieved through the following technical solutions：A kind of flow battery system leaks fast automatic
Warning device, including electrolysis liquid zone, pile area, it is characterised in that further include automatic control system, which includes
Protective fence and the current probe for being arranged on protective fence bottom, the alarm connected with current probe, the electricity
Solution liquid zone and pile area are placed in protective fence；When electrolysis liquid zone or pile area leak, the electrolyte leaked out makes
Two pole of current probe turns on, and triggers alarm equipment alarm.
The protective fence includes a ramped bottom surface, and it is minimum that the current probe is arranged on ramped bottom surface physical features
Side.
The protective fence inner surface is using ceramic paster or carries out anti-acid treatment, and the anti-acid treatment is at it
Inner surface coats epoxy resin.
The current probe includes at least two metal guide rods, current acquisition conducting wire, and multiple metal guide rod intervals are set
Put in protective fence bottom, and connected by current acquisition conducting wire, while apply the voltage of a 12~24V, form an electricity
Flow back to road；Metallic rod is turned on when electrolyte leaks, electric current is produced in the current loop, triggers alarm equipment alarm.
The minimum side of the protective fence bottom physical features is equipped with electrolyte afflux ditch, and metal guide rod is arranged on the electrolysis
It is open circuit in liquid afflux ditch, when electrolyte does not leak, between metal guide rod, does not produce electric current, when electrolyte leaks, because electrolysis
Liquid is made of vanadic sulfate, sulfuric acid solution, has larger electrical conductivity, is turned on as the metal guide rod of two poles, current loop
Produce electric current.
Multiple metal guide rods set one at interval of 0.5~1m.
Compared with prior art, the present invention has the following advantages：Go to be respectively provided with protective fence in pile area and electrolyte, prevent
The inclined-plane at inclination angle is arranged for higher end low strap at guard fence bottom, and it is minimum the electrolyte of leakage can be focused on bottom surface physical features
Side, multiple metal guide rods are set in the side, and form current loop, when there is no leak, metal by conducting wire connection guide
There is no electric conductor conducting between guide rod, therefore an open circuit, when electrolyte leaks, due to electrolyte conductivity 100~
300ms/cm, will can turn between metal guide rod, form the current loop of a conducting, so that trigger alarm equipment alarm, therefore,
Leakage can be found in first time, and can take timely remedial measure, to prevent being further developed into the major break downs such as big leakage.
