Abstract

The present invention proposes an electrolyte energy-saving transportation control device, method and liquid flow battery system, the control device includes: a positive pump; The flow rate of the positive electrode electrolyte; the second flowmeter is arranged on the outlet pipeline of the negative electrode pump, and is used to detect the flow rate of the negative electrode electrolyte output by the negative electrode pump; the controller is respectively connected with the positive electrode pump, the negative electrode pump, the first flowmeter and The second flow meter is connected to control the rotation speed of the positive electrode pump according to the flow rate of the positive electrode electrolyte, so as to adjust the flow rate of the positive electrode electrolyte output by the positive electrode pump, and to adjust the speed of the negative electrode pump according to the flow rate of the negative electrode electrolyte output by the negative electrode pump. Controlling is performed to adjust the flow rate of the negative electrode electrolyte output by the negative electrode pump. The invention can save the power consumption of the liquid flow battery system on the premise of ensuring reliable control of the electrolyte flow and pressure.

Description

technical field [0001] The invention relates to the technical field of liquid flow batteries, in particular to an electrolyte energy-saving transportation control device and method and a liquid flow battery system. Background technique [0002] At present, with regard to the liquid flow battery system, the method of setting a control valve at the outlet of the pump is mostly used to adjust the flow of the electrolyte. Although this control method can accurately control the flow, the problem is that the efficiency of the pump is reduced. In addition, due to the characteristics of the structure of the flow battery itself, there are strict requirements on the differential pressure between the positive and negative electrodes of the battery. Therefore, it is necessary to save the power consumption of the flow battery system on the premise of ensuring reliable control of the electrolyte flow and pressure. [0003] At present, an energy-efficient control method and system for a f...
