DEVICE FOR ELECTROLYSIS OF AQUEOUS SOLUTIONS Russian patent published in 2019 - IPC C25B9/08 C25B1/10 

FIELD: instrument engineering.

SUBSTANCE: invention relates to a device for electrolysis of aqueous solutions, comprising a two-chamber electrolytic cell with a housing of non-conducting material, in which there are rectangular electrodes with a diaphragm, liquid supply and discharge pipes, which are hydraulically connected to inlets of liquid bypass system, direct-current source with electrodes polarity selector and fluid bypass system control unit. Device is characterized by that in two-chamber electrolysis cell diaphragm is clamped between rectangular electrodes on both sides with triangular insulated inserts forming zigzag channel for liquid passage, having inlet and outlet nozzles for outlet of anolyte and catholyte, which are hydraulically connected to fluid bypass system consisting of first and second 2-way ball valves with rotary electric drives, and direct current source is made in the form of controlled rectifier and additionally contains rectifier control circuit, electronic switch in form of IGBT transistor, programmable time relay, generator of rectangular pulses of variable frequency, potentiometer, conductivity sensor, wherein the controlled DC rectifier with "plus" and "minus" outputs is connected on one side with the three-phase network, and on the other side with the rectifier control circuit output, electrodes in two-chamber electrolysis cell through electrode polarity switch and electronic switch in form of IGBT transistor are connected in parallel to outputs "plus" and "minus" of controlled direct current rectifier, programmable time relay by its outputs is connected to electrodes polarity switch and to rotary electric drives of first and second 2-way ball valves of liquid bypass system, generator of rectangular pulses of variable frequency with frequency of mechanical resonance of water 3,650–3,750 Hz is connected by its inputs in parallel to outputs "plus" and "minus" of controlled direct current rectifier, and by output with base of electronic switch in form of IGBT transistor, potentiometer by its output is connected to input of control circuit of rectifier and output "minus" of controlled rectifier of direct current, and input is connected to conductivity sensor located at output of first 2-way ball valve.

EFFECT: use of the proposed device allows stabilizing the output pH value and efficiently treating water and reducing energy consumption.
