Background technology
A kind of new storage battery of flow battery, flow battery is to utilize both positive and negative polarity electrolyte separately, a kind of high-performance storage battery of each self-loopa.Have the advantages that capacity is high, use field is wide, service life cycle is long.It is current a kind of new forms of energy product.
Flow battery system consists of pile, electrolyte, pipe-line system and battery management system and other auxiliary equipment.Current flow cell pile is imported and exported and is generally straight tube structure.Because pile will be tested before dispatching from the factory, in heap, can retain a part of electrolyte can not emptying.Therefore, before pile is installed, in order to prevent the leakage of the pile mouth of pipe, when pile storage and transportation logical commonly used hose by pile above and below the mouth of pipe couple together.Yet, when battery system construction is carried out pipe arrangement to pile, software need to be taken off, the electrolyte in pile can flow out by comb mouth from pile, causes the pipeline of comb mouth under pile to construct.Can only at the scene the abundant emptying of the electrolyte in pile be constructed, but it is longer to do like this time needing again, conventionally needs the time of several days could be by the abundant emptying of the electrolyte in pile, this can cause the prolongation of construction period.And the electrolyte of discharge is difficult for recycling at the construction field (site).
Utility model content
According to the technical problem of above-mentioned proposition, and a kind of flow cell pile is provided and applies the flow battery system of this pile.The utility model mainly utilizes at pipe orifice joint place and sets up pipe orifice joint spacing extender and valve, thereby has avoided the insufficient space that causes because setting up valve, greatly reduces the various risks that pile exists in storage, transportation and installation process simultaneously.
The technological means that the utility model adopts is as follows:
A flow cell pile, is characterized in that: the electrolyte liquid inlet and outlet of described pile is provided with the pipe orifice joint for being connected with electrolyte liquid inlet and outlet pipeline, and described pipe orifice joint is provided with valve.
As preferably, when described pile comprises two or more pile subelements, between the pipe orifice joint on two adjacent pile subelements, be provided with for holding the spacing of described valve.
As preferably, described spacing is setting space extender at least one pipe orifice joint in two adjacent pipe orifice joints.
As preferably, described spacing extender is the elbow of bending angle between 45 °-90 °.
The invention also discloses a kind of flow battery system, it is characterized in that: described flow battery system comprises above-mentioned flow cell pile.
As preferably, while comprising two or more piles in described flow battery system, between the pipe orifice joint on two adjacent piles, be provided with for holding the spacing I of described valve.
As preferably, described spacing I is setting space extender I at least one pipe orifice joint in two adjacent pipe orifice joints.
As preferably, described spacing extender I is the elbow of bending angle between 45 °-90 °.
As preferably, described flow battery system is all-vanadium flow battery system.
As the technical solution of the utility model, on the electrolyte liquid inlet and outlet of flow cell pile, set up the pipe orifice joint for being connected with electrolyte liquid inlet and outlet pipeline, the connected modes such as that the connected mode of pipe orifice joint is not limited to is straight-through, slip-knot, flange, groove connection, the material of pipe orifice joint is not limited to the materials such as PVC, PP, PVDF, metal, and the part contacting with liquid is resistant material; Valve is set on pipe orifice joint, and valve can be selected the valve of ball valve or other form control switches; When pile comprises two or more pile subelements or comprise two or more piles in battery system, exist insufficient space between two adjacent pipe orifice joints so that the situation of two valves to be installed, therefore, can select one or select it according to space requirement two pipe orifice joint spacing extender being set to expand two spacing between pipe orifice joint, be convenient to install; Pipe orifice joint spacing extender is preferably the parts that elbow or other can implementation space expand, and by the adjustment of pipe orifice joint spacing extender, can reserve enough spaces for mounted valve; Preferably, spacing between pipe orifice joint is 9.5cm-15cm, this spacing range is the demand that meets most flow cell piles and system thereof that size, the size of pipe orifice joint spacing extender and the factors such as model of pile according to pipe orifice joint proposes, guarantee after valve installation, between two valves, have the adjustment surplus of convenient for maintaining.
Compared with prior art, compare, the utility model can dispatch from the factory after test, directly by valve closing, to guarantee that the electrolyte that heap memory stays can not flow out from pipe orifice joint at pile; When constructing, battery system can directly at the valve place of pipe orifice joint, carry out pipe arrangement, easy construction; When battery system moves, also can by valve-off, cut off single pile at any time and be connected with battery system Ye road, operation maintenance safe ready.
The utlity model has following advantage:
1, greatly reduce the risk of pile mouth of pipe leakage in the processes such as storage, transportation and installation.
2, the difficulty that has reduced the pipe arrangement construction of pipe orifice joint place, is conducive to guarantee project quality, has reduced workmen's workload, has shortened the construction period.
3, pile and battery system can disconnect at pipe orifice joint valve place, and pile is dismantled and be easy for installation, and have reduced the risk of leakage while changing pile, are conducive to the operation maintenance of system.
4, greatly reduced the generation of on-the-spot discarded electrolyte, saved material, be conducive to promote that site environment safety is neat and artistic.
5, simple in structure, easy to manufacture, easy to install, cost is low.
The utility model can, at flow battery, preferably, can extensively be promoted in all-vanadium flow battery system field for the foregoing reasons.
