Description

Technical Field

[0001] The utility model relates to the technical field of soot recovery devices, in particular to an environmentally friendly soot recovery device for a waste heat boiler of an Aolu furnace. Background Art

[0002] The Ausmelt smelting process mainly involves sending pulverized coal, oxygen, air, etc. into the molten pool through a spray gun for stirring and chemical reaction with concentrate, solvent, etc., to quickly complete the sulfur-making and slag-making reactions. During the reaction, a copper-sulfur mixture and a large amount of SO2 flue gas will be produced. The waste heat boiler of the Ausmelt furnace uses the waste heat of the SO2 flue gas to generate steam. At the same time, some mineral powder and smoke will inevitably be entrained in the SO2 flue gas, which will flow with the flue gas and deposit in the ash room at the bottom of the waste heat boiler. The traditional practice is to arrange a shutdown time after the ash accumulation in the ash room reaches a certain level, and use a forklift to remove it and load it into the flatbed truck for transportation. This practice will cause a lot of dust during transportation, which does not meet environmental protection requirements. At the same time, the need to stop the furnace for cleaning greatly restricts the production efficiency of the Ausmelt furnace. Cleaning.
