Influence of the discharge circuit inductance on the process of galvanic wastes electrospark purification

Abstract

An effective tool for cleaning galvanic wastes from heavy metal ions is considered - a volumetric-distributed multispark submersible discharge. The general patterns of changes in the electrical characteristics of a multi-spark underwater discharge in a layer of a mixture of iron and aluminum granules depending on the inductance of the discharge circuit are revealed. The established patterns make it possible to stabilize the discharge in the course of electrospark treatment of a layer of metal granules in water. The dependences of the power amplitudes of underwater spark discharges on the inductance are formalized.
