s4: the electrolyte entering the reactor (1) is subjected to electrochemical reaction, heat is generated while discharging, and the electrolyte in the reactor (1) absorbs heat to raise the temperature;
s5: the electrolyte in the reactor (1) flows back to the liner (3) through the liquid discharge hole (11) on the reactor (1);
s7: electrolyte from the reactor (1) enters the inner container (3) and is mixed with the electrolyte in the inner container (3), and substances in the electrolyte are exchanged;
s8: and repeating the steps S2-S7, and circulating electrolyte between the reactor (1) and the liner (3), wherein the electrolyte in the liner (3) is smaller than the electrolyte in the main liquid tank (2) due to the time required by convection heat transfer, and the temperature of the electrolyte in the reactor (1) can be quickly increased.
