Title:
ELECTROLYTIC CELL OPERATION TEMPERATURE CONTROL METHOD AND SYSTEM BASED ON HEAT BALANCE CALCULATION
Document Type and Number:
WIPO Patent Application WO/2024/002161
Kind Code:
A1
Abstract:
An electrolytic cell operation temperature control method and system based on heat balance calculation. The method comprises: acquiring an actual cell front temperature of an electrolytic cell that is collected by means of a temperature collection device; if the actual cell front temperature deviates from a preset cell front temperature, controlling a refrigerant flow controller to control an intake temperature of an electrolyte, wherein the preset cell front temperature is determined on the basis of a preset cell end temperature, a correction coefficient, the net heat power of the electrolytic cell, the volume flow rate of the electrolyte, the density of the electrolyte and the specific heat capacity of the electrolyte; within the current iteration period, determining the opening degree of the refrigerant flow controller on the basis of the actual cell front temperature and the preset cell front temperature; and at the beginning of a subsequent iteration period, determining a set cell front temperature after iteration on the basis of the preset cell end temperature, the correction coefficient, size information of the electrolytic cell, an actually measured voltage, an actually measured current, an actually measured surface temperature of the electrolytic cell, an actually measured ambient temperature, the volume flow rate of the electrolyte, the density of the electrolyte and the specific heat capacity of the electrolyte, and adjusting the opening degree of the refrigerant flow controller on the basis of the set cell front temperature after iteration.
