All-vanadium flow battery (Vanadium Redox Battery, VRB) be a kind of mechanism of new electrochemical power sources, mutually transform the storage and the release that realize electric energy by the vanadium ion of different valence state, use v element of the same race composition battery system, avoided variety classes active material between positive and negative half-cell to interpenetrate the cross pollution of generation from principle.(Fig. 1) use and be dissolved in electrolyte different valence state vanadium ion as anode and negative electrode active material, anode electrolyte and negative pole electrolyte separately store, avoid battery storage process self-discharge phenomenon from principle, be suitable for extensive thermal energy storage process application.Anodal E and negative pole E that anode electrolyte storage tank B and negative pole electrolyte storage tank A are all-vanadium flow battery by magnetic drive pump D provide electrolyte, and anodal E and negative pole E ' separate by amberplex G, are power source loads C power supply.In the time that 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; In the time that Blast Furnace Top Gas Recovery Turbine Unit (TRT) can not meet rated output power, flow battery starts electric discharge, and the chemical energy storing is converted into electric energy, guarantees 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.
, on electrode, will there is following redox reaction in all-vanadium flow battery charge/discharge running.
Anodal reaction:
Negative reaction:
Because anode electrolyte and negative pole electrolyte are respectively in oxidizability valence state and reproducibility valence state, no matter be the charge/discharge running in pile inside, or electrolyte course of conveying, need to keep anode electrolyte and negative pole electrolyte 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 tanks, transfer pipeline, delivery pump etc.), if there are a large amount of leakage situation in these two regions, can find out by liquid level gauge, but will be difficult to survey if leak on a small quantity or run for a long time to leak, leak even if find a small amount of leakage in above-mentioned Er Ge district or run, it is very important taking appropriately remedial measure timely, in order to avoid produce the accidents such as large leakage.
Summary of the invention
The purpose of this utility model is exactly the fast automatic warning device that provides a kind of flow battery system safely and effectively to leak in order to overcome the defect that above-mentioned prior art exists.
The purpose of this utility model 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 of protective fence bottom, the alarm being connected with current probe, described electrolysis liquid zone and pile district are placed in protective fence; Leak when electrolysis liquid zone or pile district, the electrolyte leaking out makes current probe two utmost point conductings, causes alarm equipment alarm.
Described protective fence comprises a ramped bottom surface, and described current probe is arranged on the side that ramped bottom surface physical features is minimum.
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 therein.
Described current probe comprises at least two metal guide rods, current acquisition wire, and multiple metal guide rods are disposed on protective fence bottom, and are communicated with by current acquisition wire, apply the voltage of a 12～24V simultaneously, form a current circuit; When electrolyte leakage is by Metallic rod conducting, generation current in described current circuit, trigger alarm device is reported to the police.
The described minimum side of protective fence bottom physical features is provided with electrolyte afflux ditch, metal guide rod is arranged in this electrolyte afflux ditch, when electrolyte does not leak, between metal guide rod, for opening circuit, not generation current, when 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 utmost points, current circuit generation current.
Described multiple metal guide rods arrange one at interval of 0.5～1m.
Compared with prior art, the utlity model has following advantage: remove all to arrange protective fence in pile district and electrolyte, protective fence bottom is the low inclined-plane with inclination angle, high one end, one end, the electrolyte of leakage can be focused on to the side that bottom surface physical features is minimum, in this side, multiple metal guide rods are set, and connect guide rod formation current circuit by wire, in the time not leaking, between metal guide rod, there is no electric conductor conducting, therefore open circuit, in the time of electrolyte leakage, because the conductance of electrolyte is at 100～300ms/cm, can be by conducting between metal guide rod, form the current circuit of a conducting, thereby initiation alarm equipment alarm, therefore, can find to leak in the very first time, and can take timely remedial measure, in case be further developed into the major break downs such as large leakage.
