Problems solved by technology

[0002] The existing copper smelting slag depletion technology is used to treat copper slag. The new plant generally adopts the slag beneficiation method, while the old plant mainly adopts the electric furnace or rotary furnace depletion method. It is higher than slag beneficiation, but the investment is lower; while slag beneficiation has low copper content in waste slag and low operating costs, but the investment cost of the beneficiation plant is high and a large area of ​​open space is required for slow cooling of slag, which is not very ideal for slag dilution craft
[0003] Therefore, the copper smelting slag depletion equipment for copper slag needs to be improved

Abstract

The invention discloses an electric heating dilution furnace. The electric heating dilution furnace comprises a furnace body, a separation wall, a spraying gun and an electrode, wherein a furnace cavity is defined in the furnace body; the furnace body is provided with a smoke outlet; the separation wall is arranged in the furnace cavity for dividing the furnace cavity into a blowing area and a settling area for communicating up and down; the blowing area is provided with a charging port and a spraying gun insertion hole; the settling area is provided with an electrode insertion hole, a sulfonium outlet and a slag outlet; the spraying gun is inserted in the spraying gun insertion hole for blowing oxygen-enriched gas and a reducing agent into a slag layer in the blowing area; and the electrode is inserted in an electrode insertion hole, and extends into a slag layer in the settling area. The electric heating dilution furnace has the advantages of a side blowing furnace and the electric heating dilution furnace, and is excellent in dilution effect, high in metal recovery rate, low in investment and small in floor area.

technical field [0001] The invention relates to the field of metallurgy, in particular to an electrothermal depletion furnace. Background technique [0002] The existing copper smelting slag depletion technology is used to treat copper slag. The new plant generally adopts the slag beneficiation method, while the old plant mainly adopts the electric furnace or rotary furnace depletion method. It is higher than slag beneficiation, but the investment is lower; while slag beneficiation has low copper content in waste slag and low operating costs, but the investment cost of the beneficiation plant is high and a large area of ​​open space is required for slow cooling of slag, which is not very ideal for slag dilution craft. [0003] Therefore, the copper smelting slag depletion equipment for processing copper slag needs to be improved. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. For t...
