An industrial energy-saving high-frequency pulse electrolytic manganese device

Abstract

The invention discloses an industrial energy-saving high-frequency impulse electrolytic manganese device which comprises one or more phase-shifting transformers, one or more three-phase rectifier bridge assemblies, one or more power assemblies and a power master control unit, wherein the primary sides of the phase-shifting transformers are connected with the output end of a three-phase alternating-current supply and the secondary sides of the phase-shifting transformers are in one-to-one corresponding connection with the inputs of the three-phase rectifier bridge assemblies, respectively; the output ends of the three-phase rectifier bridge assemblies are correspondingly connected with the input ends of the power assemblies, and the output ends of the power units output high frequency impulse signals to electrolytic baths; the voltages output by the secondary sides of phase-shifting transforming units are determined according to the quantity of the electrolytic baths connected in series; when a plurality of the phase-shifting transformers are adopted, the phase-shifting transforming units are the phase-shifting transformers in multiple forms for reducing harmonic waves of an alternating current input current and harmonic amplitudes and current impulses of a direct current output voltage; the power master control unit is respectively connected with one or more power assemblies for current-sharing control of the power assemblies.

Description

technical field [0001] The invention relates to the field of electrolytic manganese, in particular to an industrialized energy-saving high-frequency pulse electrolytic manganese device, which generates DC pulses through a pulse electrolysis power supply to realize the use of pulse electrolysis to obtain metal manganese in a manganese sulfate solution. Background technique [0002] The traditional electrolytic manganese industry uses direct current electrolysis of manganese sulfate solution to obtain metal manganese, injects manganese sulfate water-soluble electrolyte containing ammonium sulfate into the diaphragm electrolytic cell, connects direct current, produces electrolysis, and precipitates metal manganese on the cathode plate, and the anode Oxygen is precipitated from the plate; the cathode plate is periodically replaced, and the electrolysis product is passivated, washed, dried, and stripped to obtain metal manganese products. [0003] Since the industrial power suppl...
