Description

Technical Field

[0001] The utility model relates to the technical field of zinc slag recovery, in particular to a zinc slag smelting recovery furnace. Background Art

[0002] Zinc slag smelting recovery furnace is an industrial equipment used to treat zinc-containing waste slag such as zinc leaching slag and recover valuable metals therein.

[0003] A current Chinese patent (publication number: CN2325402Y) proposes a zinc slag recovery furnace for recovering zinc slag and scrap. It consists of a combustion chamber and a zinc-making chamber. The combustion chamber has four grate bars supporting four inclined grate bars and a refractory concrete cover on top. The zinc-making chamber has three zinc-roasting pools and six zinc crucibles. The sloped bottoms of the zinc-roasting pools facilitate the timely flow of melted zinc slag into the crucibles, preventing it from re-condensing and forming slag. A fire channel surrounds the zinc-making chamber between the zinc-making chamber and the furnace exterior, exposing it to the full heat and reaching temperatures exceeding 850°C. This increases the zinc slag recovery rate to over 22%, effectively achieving optimal secondary recovery of zinc slag waste.

[0004] In the above technical solution, the zinc-making chamber can be fully exposed to fire, so that the temperature of the zinc-making chamber can reach above 850°C. The zinc frying pool uses silicon carbide or other materials with good thermal conductivity, which makes it have fast heat transfer, high thermal efficiency, and is not easy to oxidize. The zinc slag smelting recovery rate can be increased to more than 22%, truly realizing the secondary better recovery of zinc slag waste.

[0005] However, the oxygen flow rate of the vent in the above-mentioned device is fixed. In the stage where rapid reaction is required, the fixed oxygen flow rate may not provide enough oxygen to support the rapid reaction, thereby affecting the overall smelting speed and efficiency. Excessive oxygen flow rate will lead to energy waste, because the excess oxygen does not effectively participate in the combustion reaction, increasing unnecessary energy consumption. Therefore, we proposed a zinc slag smelting recovery furnace. Utility Model Content
