Novel furnace used for antimony ore side blowing and flash mixing molten pool smelting

Abstract

The invention discloses a novel furnace used for antimony ore side blowing and flash mixing molten pool smelting. The novel furnace comprises a furnace body and a furnace cavity formed in the furnacebody. The furnace body comprises a furnace top, a furnace main body, a furnace bosh water jacket and a furnace hearth. Side blowing air pipes and a flash powder spray nozzle are arranged on the furnace body. One or more flash powder jet nozzles are arranged on the top or the side face of a molten pool. The flash powder spray nozzle and the flash powder jet nozzle communicate with the furnace cavity. A material storage bin is arranged on the furnace top. A flue communicating with the furnace cavity of the furnace main body is arranged on the side wall of the furnace main body. The furnace boshwater jacket is arranged on the lower portion of the furnace main body. The side blowing air pipes communicating with the furnace cavity are arranged on the side wall of the furnace bosh water jacket.The molten pool furnace hearth made of a fire-resistant material is arranged at the bottom of the furnace bosh water jacket, and an inner side wall of the molten pool furnace hearth is provided witha residue passing way or a residue outlet and an antimony matte opening. By means of the technical scheme, productivity can be effectively improved, the energy consumption can be reduced, and economicand technical indexes can be improved.

Description

technical field [0001] The invention relates to a new type of furnace for smelting antimony ore in a side-blown flash mixed molten pool. Background technique [0002] Traditional antimony ore rough smelting processes are popularly applied in three processes: vertical shaft furnace volatilization roasting, open hearth bottom blowing volatilization roasting, and blast furnace volatilization smelting. Among them, vertical shaft furnace volatilization roasting and open hearth bottom blowing volatilization roasting are adopted by the state due to low production capacity and high labor intensity. Listed as eliminating backward production capacity. The traditional antimony ore rough smelting process is now mainly antimony blast furnace volatilization smelting process. The specific plan is to mix the fine ore into balls and lump ore together with coke, iron ore, limestone, etc. in appropriate proportions, and classify and batch from the top of the furnace. The warehouse is put into...

AI Technical Summary

Problems solved by technology

However, the blast furnace volatilization smelting process has high energy consumption and tail gas SO 2 The concentration is too low to make acid, and the economic benefits are not ideal. There has been almost no technological upgrading and progress in the development for half a century, which seriously restricts the development of the industry. Compared with other non-ferrous metal smelting new technologies, it has gradually fallen behind. There is a gap in energy saving and emission reduction process requirements
