Power supply control circuit used for preparing disinfectant through direct-current electrolysis in slightly alkaline environment

Abstract

The invention provides a power supply control circuit for preparing a disinfectant through direct-current electrolysis in a slightly alkaline environment. The power supply control circuit comprises alow-voltage direct-current power supply and an electrode plate array connected with the low-voltage direct-current power supply; the low-voltage direct-current power supply supplies power to the electrode plate array; the output voltage of the low-voltage direct-current power supply is 1V-24V; the electrode plate array is composed of a net-shaped anode and a net-shaped cathode which are closely arranged in parallel; the distance between the net-shaped anode and the net-shaped cathode ranges from 0.5 mm to 2.5 mm; brine between the anode and the cathode can freely flow so that the pH value range of the liquid environment in the electrolysis process can be maintained to be 8 and 10. When saline water is electrolyzed, the low-voltage direct-current power supply detects current output by the electrode plate array; when the liquid level of the saline water descends, and the area, exposed from the liquid level, of the electrode plate array is larger than a threshold value, the variable quantity of the current output by the electrode plate array is larger than the threshold value, and the power supply control circuit stops supplying power to the electrode plate array. According to the power supply control circuit, domestic disinfectant fluid can be prepared by the diaphragm-free brine electrolysis method, the problem of gas deflagration of the diaphragm-free brine electrolysis methodis solved, and the product can be safely used for domestic hygiene 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.
