Alkali liquor circulation control method for alkaline water electrolysis hydrogen production system

The invention belongs to the technical field of electrolytic hydrogen production circulation control, and particularly relates to an alkali liquor circulation control method for an alkaline water electrolytic hydrogen production system, which comprises the following steps: arranging a stirring terminal in an electrolytic tank, and installing a thermal infrared imager, so that electrolyte temperature distribution analysis is performed by virtue of the thermal infrared imager when the electrolyte temperature is collected; the method comprises the following steps: analyzing the electrolyte in the electrolytic tank, controlling a stirring terminal to stir the electrolyte according to an analysis result, obtaining the effective temperature of the electrolyte from a stirring result, really and reliably obtaining the temperature of the electrolyte, and arranging a temperature control element around the electrolytic tank, so that the electrolyte in the electrolytic tank can be covered in a temperature control range o
