High-grade matte nickel production device and production method

The invention provides a high-grade matte nickel production device and method, the high-grade matte nickel production device comprises a furnace body, the furnace body is sequentially divided into a smelting area, a settling area, a vulcanization area and a discharge area, the upper end of the smelting area is provided with a reduction space, the side wall of the smelting area is communicated with a first spray pipe, the first spray pipe is used for spraying a mixture of fuel and oxygen into the smelting area, and the side wall of the vulcanization area is communicated with a second spray pipe; the second spraying pipe is used for spraying a vulcanizing agent into the vulcanizing area, and the upper end of the discharging area communicates with a smoke discharging channel. According to the high-grade matte nickel production device and method, coke and sintering are not needed, the high-grade matte nickel is produced in one step after the laterite-nickel ore powder enters the furnace, the blowing process is om
