Description
Technical Field
The invention relates to an all-vanadium redox flow battery system applied to efficient energy storage.
Background
With the increasing concern of people on environmental problems such as air pollution caused by fire coal, petroleum and the like and the energy shortage which is generally faced in the world, the research of energy materials has always become the leading edge and the hot spot of material science, particularly, the research of energy materials has become the front edge and the hot spot of material science, particularly, the research of energy materials has required a large-capacity electricity storage device by utilizing green and renewable wind energy and solar energy due to the characteristics of discontinuous electricity generation and the like, and the all-vanadium redox flow battery has become the hot spot of the industrial development of the energy storage industry due to the advantages of large-scale energy storage, environmental friendliness, deep charge and.
As shown in FIG. 1, the all vanadium liquid flow energy storage system is composed of a 7 '-galvanic pile system, an electrolyte and conveying system (1' -anode liquid storage tank, 3 '-cathode liquid storage tank and the like), and an 8' -management and detection system. Generally, the whole system is on a plane, and the positive electrode and the negative electrode respectively adopt a pumping system to convey electrolyte in a closed loop in the charge-discharge process to achieve charge-discharge; in the operation process, the pump needs to be operated continuously, the pump consumes 3-7% of energy of the whole system, the pump generates heat seriously and is used continuously in the charging and discharging process, so that the service life of the pump is greatly reduced, and when the system is charged to full charge and is not used temporarily, the migration of ions in the diaphragm causes serious self-discharge, and about 5-10% of energy consumption is caused. The system generally enters from the lower port and the upper port of a 7-electric pile system, and the anode and the cathode are respectively provided with a storage tank.
In the whole system charge-discharge process, the positive and negative pumps need to run in real time to ensure the progress of charge or discharge reaction, and in the running process, the charge state of the electrolyte in the storage tank is changed in real time along with the progress of charge and discharge, so that the accurate detection cannot be realized; when the system is charged to a full-charge state and is not used for a short time, the self-discharge is serious due to the diaphragm, and simultaneously, energy is consumed to drive the pump when the system is charged and discharged, so that the efficiency of the system is very low, and the general comprehensive electricity storage efficiency is lower than 70%; and because the pump is used continuously, the pump generates heat seriously, the service life is greatly reduced, and the pump needs to be replaced generally about 1 to 3 years, so that the system maintenance and replacement cost is increased, and the reliability is greatly reduced. In addition, the liquid inlet mode of the system generally adopts downward inlet and upward outlet, so that the internal pressure of the system is higher, the sealing requirement is higher, and the problems of serious ion migration between a positive electrode and a negative electrode and the like caused by unbalanced pressure on two sides exist.
The pumping system used by the vanadium redox flow battery enables electrolyte to respectively run in the whole closed positive and negative electrode pile and the pipeline system, but the electrolyte of the vanadium redox flow battery is corrosive liquid, and meanwhile, the viscosity of the electrolyte is high, so that a pump required by the vanadium redox flow battery needs acid resistance and corrosion resistance, and when the vanadium redox flow battery continuously runs, the power consumption of the pump is high, the heat is serious, the service life of the pump is short, and the reliability and stability of the whole system are seriously influenced. Meanwhile, a pump of the vanadium battery energy storage system needs to consume 3-7% of energy of the whole energy storage system, in addition, in the charging and discharging process, the charge state is in continuous change, and the defects of insufficient reaction, real-time change of the charge state, incapability of effective monitoring and the like exist in the conventional system; self-discharge is severe when charged to a fully charged state and left unused for a short period of time. Meanwhile, liquid flows enter from the lower opening of the galvanic pile at a low position and exit from the upper opening of the galvanic pile at a high position, so that the internal pressure of the galvanic pile is high, and the sealing of the galvanic pile and the pressure balance at two sides are greatly influenced. Therefore, the current system configuration is optimized, the service life of the pump is prolonged, the heating is reduced, the consumption of the pump on the energy of the whole system is reduced, the anode and the cathode fully react, the self-discharge is reduced, the pressure of the anode and the cathode is balanced, the reliability and the stability of the whole energy storage system are improved, the service life is prolonged, the self-consumption of the energy is reduced, the energy efficiency is improved, and the method is of great importance for exerting the advantages of the vanadium battery energy storage system.
