Power supply control circuit for the preparation of disinfectant by direct current electrolysis in an alkaline environment

Abstract

The present invention proposes a power supply control circuit for preparing disinfectant by DC electrolysis in an alkaline environment, including a low-voltage DC power supply and an electrode sheet array connected thereto; the low-voltage DC power supply supplies power to the electrode sheet array and the output voltage is 1V~24V; The electrode sheet array is composed of mesh anodes and mesh cathodes arranged in close parallel with a spacing range of 0.5mm~2.5mm. The brine between the anodes and cathodes can flow freely to maintain the pH range of the liquid environment during the electrolysis process at pH8~pH10; When electrolyzing salt water, the low-voltage DC power supply detects the current output by the electrode array. When the liquid level of the brine drops and the area of ​​the electrode array exposed to the liquid surface is greater than the threshold value, the change in current output by the electrode array is greater than the threshold value. Power supply The control circuit stops the power supply to the electrode sheet array; the invention can prepare household disinfectant water by electrolysis of salt water without diaphragm, and solves the problem of gas deflagration in the electrolysis of salt water without diaphragm, so that the product can be safely used for household sanitation and disinfection.

Description

technical field [0001] The invention relates to the technical field of sanitary equipment, in particular to a power supply control circuit for preparing disinfectant by direct current electrolysis in an alkaline environment. Background technique [0002] The electrolysis of brine can generate sodium hypochlorite solution for sanitation and disinfection, but the traditional electrolysis brine device needs to be equipped with a diaphragm, which increases the cost too much, which is not conducive to the household use of this type of electrolysis device, and the brine electrolysis equipment without diaphragm Although the components used are cheap, it is necessary to consider the safety of the flammable gas generated during the electrolysis process. How to apply the membrane-free brine electrolysis technology to households to prepare disinfectant water that can be used for household sterilization and disinfection operations is a research direction.
