Abstract

The invention discloses an aluminum electrolyzed waste carbon residue innocent treatment system and a method thereof, and aims at solving the technical problems of low carbon residue reclaiming utilization and environmental pollution in current electrolytic aluminum industry. The system comprises a heating furnace, a heating circulation device, a tail gas purification device, a hopper correspondingly communicated with the heating furnace and a raw material bin correspondingly communicated with the hopper, wherein the heating circulation device is respectively and correspondingly communicated with the heating furnace and the raw material bin; a tail gas outlet communicated with the tail gas purification device is formed in the raw material bin. According to the aluminum electrolyzed waste carbon residue innocent treatment system, the problems that accumulation or landfill of waste slot liner carbon residues pollutes environment, massive raw materials are wasted and the like, which trouble the electrolytic aluminum industry for years, can be effectively solved.

Description

technical field [0001] The invention relates to a waste carbon slag treatment system and method thereof, in particular to a harmless treatment system and method for aluminum electrolysis waste carbon slag. Background technique [0002] Aluminum is an important basic industrial raw material. Electrolytic aluminum belongs to the important light non-ferrous metal industry and occupies a very important position in the national economy. It has been widely used in transportation, national defense, electric power, machinery, construction, light industry, aerospace and other industries. In, and with the continuous development of science and technology, the application of aluminum will be more extensive. In the process of electrolytic aluminum production, due to various reasons such as the anode carbon body not fully participating in the reaction, long-term erosion and washing by the electrolyte, and unqualified quality, carbon slag will be formed in the electrolytic cell; while the ...
