Description

Technical Field

[0001] The utility model relates to the technical field of flash furnaces, and particularly relates to a dust collection device for a flash furnace. Background Art

[0002] When a flash smelting furnace uses high-grade copper matte powder for suspension smelting, the incidence of soot is high and the viscosity of the soot is large. The upcomer is the flow passage for the flue gas of the copper flash smelting furnace to enter the waste heat boiler. When the flue gas passes through the transition section connected to the boiler in the upcomer, the temperature will drop rapidly, causing the high-temperature soot particles wrapped in the flue gas to cool and settle quickly. However, the flue gas is discharged without thorough cooling and physicochemical reactions, with a relatively high temperature and large amount of soot, resulting in a certain degree of air pollution.
