High-temperature continuous treatment system for disposing waste cathode of electrolytic aluminum

Abstract

The invention relates to the technical field of the treatment of solid waste substances, and particularly relates to a high-temperature continuous treatment system for disposing a waste cathode of electrolytic aluminum. The invention provides the high-temperature continuous treatment system for disposing the waste cathode of the electrolytic aluminum. The high-temperature continuous treatment system comprises a crushing system, a feed system, a roasting system, a fume treatment system and a solid particulate matter treatment system, wherein the crushing system is used for crushing a charcoal block of the waste cathode of the electrolytic aluminum to form particulate material and conveying the particulate material to the roasting system by the feed system; the roasting system comprises an electric calcining furnace, a gas discharge opening is formed in the upper end of the electric calcining furnace, and a solid discharge opening is formed in the lower end of the electric calcining furnace; the fume treatment system is connected with the gas discharge opening; the solid particulate matter treatment system is connected with the solid discharge opening. By the system, a fluoride salt and a carbon product which are high in quality and further have economic value added are obtained; further, the system is simple in structure, convenient to operate and low in energy consumption and cost, has innocent treatment, and improves the treatment efficiency and the resource utilization efficiency of the charcoal block of the waste cathode of the electrolytic aluminum.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to a high-temperature continuous treatment system for disposing of waste cathodes of electrolytic aluminum, in particular to a system with low energy consumption, low cost, thorough harmless treatment and the ability to effectively improve the solid state of electrolytic aluminum A high-temperature continuous treatment system for disposing of electrolytic aluminum waste cathodes for waste treatment efficiency and resource utilization efficiency. Background technique [0002] As the production of electrolytic aluminum increases, so does the solid waste generated during the electrolysis process. Among them, the electrolytic aluminum waste is the most harmful electrolytic aluminum cathode. The electrolytic aluminum cathode is made of calcined anthracite, metallurgical coke, graphite, etc. as aggregates, coal tar pitch and other binders, and is mainly used to make carbon l...
