Below with reference to the continual lead smelting device of Fig. 1-3 description according to the utility model embodiment.
As Figure 1-3, the continual lead smelting device according to the utility model embodiment comprises Reaktionsofen 1, oxidation zone side-blown spray gun 2 and reduction zone side-blown spray gun 3.
Be provided with partition wall 4 in the Reaktionsofen 1, partition wall 4 is divided into oxidation zone Y and reduction zone H with the furnace chamber of Reaktionsofen 1, and the bottom of partition wall 4 is provided with the communication passage 41 that is communicated with oxidation zone Y and reduction zone H.The bottom of the furnace chamber of Reaktionsofen 1 constitutes the molten bath, and in the molten bath, L1 is the liquid level of slag, and L2 is the liquid level of lead bullion.In a concrete example of the present utility model, Reaktionsofen 1 can be the fixedly horizontal reacting container of long ellipse shape.Therefore, the Reaktionsofen 1 according to the utility model embodiment also can be called fixedly horizontal chamber oven.The diapire of the furnace chamber of reflection stove 1 can be recessed arc, as shown in Figure 3.
Be respectively equipped with oxidation zone charging opening 11 and oxidation zone smoke outlet 12 on the roof of oxidation zone Y.The roof of reduction zone H is provided with reductive agent and adds inlet 13 and reduction zone smoke outlet 14.The furnace wall of the furnace chamber of Reaktionsofen 1 is provided with siphon lead tap 18 and slag notch 20.
Oxidation zone side-blown spray gun 2 links to each other with the oxidation zone sidewall of Reaktionsofen 1 in the molten bath with oxidation zone Y that industrial oxygen (or oxygen-rich air) is blown side, thereby lead-containing material is carried out melting.Reduction zone side-blown spray gun 3 link to each other with the reduction zone sidewall of Reaktionsofen 1 with fuel and oxygen side-blowing in the molten bath of reduction zone H.
As shown in Figure 1, more specifically, oxidation zone side-blown spray gun 2 is injected to oxidation with industrial oxygen and goes under the liquid level L1 of slag on the liquid level L2 of lead bullion in the molten bath of Y, in other words, oxidation zone side-blown spray gun 2 is injected to industrial oxygen in the rich lead skim in the oxidation zone Y, reduction zone side-blown spray gun 3 is injected to fuel and oxygen in the slag in the H of reduction zone, thereby in the H of reduction zone, the not lead bullion that restored of oxidation repeatedly of fuel in the molten bath of reduction zone H and oxygen is gone in reduction zone side-blown spray gun 3 side-blown.
Continual lead smelting device according to the utility model embodiment, also can be called continuous side-blown and refine plumbous device, lead-containing material (for example lead ore concentrate) and flux join in the oxidation zone Y from oxidation zone charging opening 11, and the industrial oxygen that sprays into by oxidation zone side-blown spray gun 2 carries out melting to lead ore concentrate and obtains lead bullion and rich lead skim.Rich lead skim in the oxidation zone Y flows in the H of reduction zone from the communication passage 41 (being the bottom surface of partition wall 4 and the passage between the furnace chamber bottom surface) of partition wall 4 bottoms.From reductive agent add inlet 13 in the H of reduction zone, add reductive agent for example beans the lead the rich lead skim is reduced, and spray into fuel and oxygen to keep the temperature of reduction zone H by the slag inboard of reduction zone side-blown spray gun 3 in the H of reduction zone.It will be appreciated that by the control straying quatity, the part of fuel that reduction zone side-blown spray gun 3 sprays into also can be made reductive agent and reduce rich lead skim simultaneously with the beans of adding.
Continual lead smelting device according to the utility model embodiment, in single Reaktionsofen 1, can realize oxidation and reduction, and owing to take side-blown, therefore fuel that H blows side in the reduction zone and oxygen are without the lead bullion that has restored, therefore oxidation lead bullion repeatedly not, lead tolerance reduces and stable in the slag.And oxidation zone Y and reduction zone H separate, and only the communication passage 41 by partition wall 4 bottoms is communicated with, communication passage 41 is immersed in the melt when operation, so the upper isolation of oxidation zone Y and reduction zone H, the flue gas of oxidation zone and reduction zone can not mix, and can distinguish individual curing.Owing to realized continual lead smelting in the Reaktionsofen of single sealing, so good seal performance, feature of environmental protection height has made full use of the heat content of slag, has reduced energy consumption.
