WO2006052165B1 - Plasma reactor-separator - Google Patents

Abstract

The invention can be used for the cement, chemical and metallurgical industries. The inventive plasma reactor-separator for simultaneously producing the melt of high-melting metal and non-metal materials and fumes comprises a longitudinal hollow partition (17) which is refrigerated from the inside thereof by a raw material and divides a chamber (1) into two equal parts. Said partition is provided with horizontal slit-type openings for material discharging and for additional kish (20) formation in the form of conical slopes on a heel of metal boundaries. Said reactor also comprises hollow stick electrodes (2, 3) whose lower ends are introduced into the melt. The partition (17) is provided with an arc hole which is arranged above the melt surface. Coils (11) make it possible to rotate the melt on a horizontal plane by means of electromagnetic forces for removing a solid raw material from under the electrode and for moving said material in the arcing area. Said invention makes it possible to substantially increase the operational reliability and service life of electrodes, to increase the reactor performance, improve a final product quality and to reduce energy consumption.
