Description

Ring smoke collecting hood system for intermediate chute of two-link furnace

Technical Field

The utility model relates to the technical field of metallurgy, concretely relates to ring collection petticoat pipe system that is used for two to link furnace intermediate chute.

Background

SO in copper smelting₂Is the main atmospheric pollutant, SO in the production process₂The flue gas can be dissipated into the air when the melt is poured out of the furnace body, flows through the middle chute and enters the furnace body, so that the health of people is harmed and surrounding buildings are corroded, and therefore the annular flue gas dissipated into the air needs to be collected.
