Abstract
The utility model relates to a flow battery for an off-grid wind and light complementary power supply system. The flow battery comprises cathode electrolyte, anode electrolyte and a battery stack. The battery stack comprises collector plates and a diaphragm. A square tank is arranged on each collector plate. An electrolyte inlet and an electrolyte outlet are respectively arranged at the two ends of the square tank. The electrolyte inlet and the electrolyte outlet are respectively arranged on the two sides of one diagonal line in the square tank and avoid the corners of the square tank. When the flow battery is used, electrolyte is circulated between the collector plates and storage tanks through pumps and pipelines, the two adjacent collector plates are respectively connected with the cathode electrolyte and the anode electrolyte, and electrons in the electrolyte are migrated between the cathode electrolyte and the anode electrolyte through the diaphragm between the two adjacent collector plates to generate current to complete charge and discharge. The flow battery for the off-grid wind and light complementary power supply system has the effects that the funneling effect is weakened, the pressure change of the electrolyte passing through the electrolyte inlet and the electrolyte outlet is small, the corrosion effect of the electrolyte on the electrolyte inlet and the electrolyte outlet is reduced, the service life of the collector plates is prolonged and the use and maintenance costs of the flow battery are reduced; and the flow battery has the advantages of long service life, low maintenance cost and the like.
Description
Technical field
The utility model relates to a kind of net wind-photovoltaic complementary power supply system that leaves and uses flow battery, belongs to the battery technology field.
Background technology
At present; The wind and solar energy equal energy source since its sustainable regeneration advantage by popularization and application in power field; But there are discontinuity in wind energy, solar energy; In use need dispose energy storage device, and flow battery because its flexible design, have extended cycle life, energy storage density is big, cost is low etc., and advantage becomes first-selected energy storage device.
Existing flow battery mainly is a vanadium oxide reduction flow model flow battery, rely on independently two pumps form respectively anolyte and catholyte at battery at indoor mobile of positive and negative electrode, electronics produces electric current through the barrier film between the positive and negative electrode chamber.Because V electrolyte has severe corrosive and oxidizability; Collector plate is corroded in long-play easily; Appearance electrolyte permeability etc. jeopardizes the problem of battery structure and capacity, just needs to change the stable operation of collector plate with the assurance battery this moment, causes the working service cost of flow battery higher.Research through the inventor; The position that collector plate is corroded mainly concentrates on the liquid in-out mouth; The liquid inlet and outlet of existing collector plate is positioned on the diagonal of square groove of collector plate; Form funnel-shaped structures with two limits of square groove, electrolyte makes the surface texture easy fatigue of runner to the pressure generating period property variation of runner when passing in and out from here, and the pressure of the electrolyte liquid that flows further makes the structure spalling of fatigue and causes corrosion with corrosiveness.
The utility model content
The technical problem that the utility model will solve is; To the existing deficiency that current collector of liquid flow battery plate liquid in-out mouth is corroded easily, the working service cost is high, propose a kind of net wind-photovoltaic complementary power supply system that leaves and use flow battery with collector plate of corrosion resistant liquid inlet and outlet.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of net wind-photovoltaic complementary power supply system that leaves is used flow battery; Comprise catholyte, anolyte and battery pile; Said battery pile comprises collector plate and barrier film; Said collector plate is provided with square groove, and the two ends of said slot electrode are respectively equipped with liquid inlet and outlet, and said liquid inlet and outlet lays respectively at the interior cornerwise both sides of said square groove and staggers with the turning of square groove.
The structure that wind-photovoltaic complementary power supply system staggers owing to employing liquid inlet and outlet and square groove turning on collector plate with flow battery is netted in leaving of the utility model; The beneficial effect that has is: weakened funneling effect; Electrolyte pressure through liquid inlet and outlet the time changes little; Thereby weakened the corrosiveness of electrolyte, prolonged the life-span of collector plate, reduced the working service cost of flow battery liquid inlet and outlet.
Description of drawings
Below in conjunction with accompanying drawing being described further with flow battery to the utility model from the net wind-photovoltaic complementary power supply system.
Fig. 1 nets the structural representation of wind-photovoltaic complementary power supply system with flow battery leaving of the utility model.
Fig. 2 is the partial schematic diagram of Fig. 1.
Fig. 3 is the structural representation of the collector plate of existing flow battery use.
Embodiment
Embodiment
Leaving of present embodiment netted wind-photovoltaic complementary power supply system with flow battery such as Fig. 1, shown in Figure 2; Comprise: catholyte 1, anolyte 2 and battery pile 3; Battery pile 3 comprises collector plate 4 and barrier film 5, and collector plate 4 is provided with square groove 6, and the two ends of square groove 6 are respectively equipped with inlet 7 and liquid outlet 8; Inlet 7 is positioned at a side of square groove inner opposite angle line, and liquid outlet 8 is positioned at the opposite side of square groove inner opposite angle line, and inlet 7, liquid outlet 8 all stagger with the turning of square groove 6.
During use; Electrolyte circulates between collector plate and storage tank through pump and pipeline; Two adjacent collector plate connect catholyte and anolyte respectively; Electronics in the electrolyte moves between catholyte and anolyte through the barrier film between two adjacent collector plate, thereby produces electric current, accomplishes the charge or discharge process.
Wind-photovoltaic complementary power supply system is compared existing flow battery as shown in Figure 3 with the collector plate of flow battery collector plate is netted in leaving of the utility model; Because liquid outlet is not connected on the turning of square groove; Electrolyte funneling effect through into and out of collector plate the time a little less than; Through the useful life of collector plate being prolonged effectively, avoid the generation of leakage through evidence.
The net wind-photovoltaic complementary power supply system that leaves of the utility model is not limited to above-mentioned each embodiment with flow battery, and all employings are equal to for the technical scheme that forms, and all drop on the protection range of the utility model requirement.
