In-furnace desulfurization device for ore processing

Abstract

The invention discloses an in-furnace desulfurization device for ore processing. The in-furnace desulfurization device comprises a processing furnace, an oxygen supply structure, a heating structure and a desulfurization structure. The processing furnace is of a hollow cylindrical structure, a desulfurization cavity, an oxidation reaction cavity and a heating oxygen supply cavity are sequentially formed in the processing furnace from top to bottom, two feeding and discharging openings corresponding to the desulfurization cavity and the oxidation reaction cavity correspondingly are formed in the circumferential surface of the processing furnace, and sealing door structures are arranged at the feeding and discharging openings; and the oxygen supply structure is positioned in the oxidation reaction cavity; The in-furnace desulfurization device is provided with the corresponding oxygen supply structure, on the premise that it is guaranteed that the interior of the processing furnace is relatively sealed and sulfur oxides are prevented from directly entering air, oxidation of sulfur elements in ore is accelerated, then desulfurization treatment on the ore is achieved, the time needed for heating desulfurization by directly utilizing a quick lime layer and a slaked lime layer traditionally is greatly shortened, and the desulfurization efficiency of ore in the furnace is greatly improved.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to an in-furnace desulfurization device for ore processing. Background technique [0002] my country is a country with a large infrastructure, so the development of the metallurgical industry is relatively rapid. However, in the process of industrial metallurgy, a large amount of sulfur oxides will always appear, causing extremely serious environmental pollution. In order to reduce the discharge of sulfur oxides in the metallurgical process , the in-furnace desulfurization technology of ore processing has been paid more and more attention by more and more people. The traditional in-furnace desulfurization method is to add quicklime or slaked lime to the furnace to remove sulfur in the ore. The sealed structure only uses heating to desulfurize by mixing quicklime or slaked lime with ore. This method cannot quickly realize the rapid oxidation of sulfur inside the ore. Th...

[0002] my country is a country with a large infrastructure, so the development of the metallurgical industry is relatively rapid. However, in the process of industrial metallurgy, a large amount of sulfur oxides will always appear, causing extremely serious environmental pollution. In order to reduce the discharge of sulfur oxides in the metallurgical process , the in-furnace desulfurization technology of ore processing has been paid more and more attention by more and more people. The traditional in-furnace desulfurization method is to add quicklime or slaked lime to the furnace to remove sulfur in the ore. The sealed structure only uses heating to desulfurize by mixing quicklime or slaked lime with ore. This method cannot quickly realize the rapid oxidation of sulfur inside the ore. Therefore, we propose a method for ore In-furnace desulfurization device for processing
