DEVICE FOR COLLECTING GASES EMITTED BY ALUMINUM ELECTROLYSIS TANKS, AND ASSOCIATED ALUMINUM PRODUCTION SYSTEM

摘要

the invention relates to a device for collecting (6) capable of collecting the gases emitted by various aluminum electrolytic cells, characterized in that it comprises at least one bypass loop (20) of the gas flow, and connected at each of its ends to the collection device (6).the bypass loop (20) is able to pass through a medium whose temperature is lower than the temperature of the gas.
