Abstract

The invention relates to a coarse zinc smelting furnace which comprises a vertical furnace body. Multiple layers of combustion chambers are arranged in the vertical furnace body. Each layer of combustion chamber is provided with nozzles used for injecting coal gas or air. A plurality of smelting pots are arranged in each layer of combustion chamber. Pot openings of the smelting pots are all formed in the outer wall of the vertical furnace body. Two flues are also arranged in the vertical furnace body and located at the two ends of the multiple layers of combustion chambers respectively. The two flues are communicated with the two ends of the multiple layers of combustion chambers respectively. The portions, corresponding to each layer of combustion chamber, of the two flues are each provided with a first electromagnetic valve. The upper ends of the two flues are communicated through a pipeline, and a second electromagnetic valve is arranged at the communicated position of the two flues. The second electromagnetic valve is connected with a flue gas cleaner. Compared with the prior art, the coarse zinc smelting furnace can control flue gas emission amount and purify flue gas, saves energy and is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of smelting, in particular to a crude zinc smelting furnace. Background technique [0002] In the prior art, metal zinc smelting methods are mainly divided into wet method and pyromethod. The investment of hydrometallurgy is huge, wastewater treatment is difficult, and the selectivity to raw materials is strong; pyrometallurgy includes vertical tank smelting, blast furnace smelting and electric furnace Smelting, etc., all have disadvantages such as large investment, high production cost, and low heat energy utilization rate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a crude zinc smelting furnace capable of controlling the discharge of flue gas, purifying the flue gas, and being energy-saving and environment-friendly. [0004] The technical scheme of the present invention to solve the above-mentioned technical problems is as follows: a crud...
