The invention relates to electrical and magnetic water treatment and can be used in water and heat supply systems.

The purpose of the invention is to reduce energy consumption during non-reagent water treatment.

The drawing shows a block diagram of the power supply device of the non-reagent water treatment plant.

The device contains an alternating current source 1, thyristors 2 and 3, electrolysis cells 4 and 5, an electromagnet 6 and a phase control unit 7 for rectifying elements.

The device works as follows.

direct current flows with the treated water, and the reverse current passes through the first electrolyzer 4 and electromagnet 6. Since the reverse current source component of the source includes an electromagnet 6, the power consumption of which is less than the power consumed by electrolyzers, the resistance in the reverse current circuit is less, and accordingly, less current than in the forward current component circuit. With such a power supply device, there is no need for an additional power supply unit for the electromagnet 6. If necessary, change the effective or average value of the voltage and current in the load and unload the control unit. Assume that the first and subsequent output pulses

thyristor control electrode 2 and 3. In this case, the thyristor switching angle changes, which leads to the required change in the effective or average voltage and current in the load.

Invention Formula The odd half-periods of the current variation of the voltage applied to the connection point of thyristors 2 and 3 is positive, and the voltage applied to the connection point of electrolyzers 4 and 5 is negative. Then, on the second and next even half periods, the polarity of the source voltage at these points is opposite.
