Abstract

The invention discloses a wet process zinc smelting slag drying and sintering device and method, and aims at avoiding the material bonding in the drying process and solving the problems that a large amount of material smoke dust is brought away by drying smoke gas, and the smoke gas temperature is high. The wet process zinc smelting slag drying and sintering device has the technical scheme that the wet process zinc smelting slag drying and sintering device comprises a tube body (3) arranged in a way of being vertical to the horizontal plane, wherein a firebrick is lined in the tube body (3), a material inlet and a material outlet are formed in the tube body (3), the bottom of the tube body (3) is provided with an air inlet, the top of the tube body (3) is provided with a flue (1), a feeding mechanism (2) is arranged at the material inlet part of the tube body (3), a discharging mechanism is arranged in the material outlet of the tube body (3), and the lower end of the discharging mechanism is provided with a transportation mechanism (11).

Description

technical field [0001] The invention belongs to the technical field of zinc smelting, and in particular relates to a wet-process zinc smelting slag drying and sintering device and method. Background technique [0002] Non-ferrous metal zinc smelting has two processes: wet method and pyrolysis method. The wet method smelting process is adopted, and the main processes include leaching, purification and electrolysis. Among them, the recovery of non-ferrous metals is mainly in two processes of oozing out and purification. The recovery of the main metal zinc is mainly manifested in the effect of leaching, so that the slag content of the metal zinc is reduced to 2-5%, and at the same time, the silver content is enriched to 600g-800g / t, and the slag lead content is enriched to 10-20%. The collection of valuable metals lead and silver has become an important task, and the choice of process is crucial to the recovery cost. The silver-lead slag is added to the bottom-blown furnace to...
