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

Abstract

The invention discloses an antimony ore bottom blowing flash mixing molten pool smelting converter. The antimony ore bottom blowing flash mixing molten pool smelting converter comprises a horizontal cylindrical furnace body. The furnace body comprises a furnace body shell and a furnace cavity arranged in the furnace body shell. A refractory material is arranged between the furnace body shell and the furnace cavity. A walking gear for controlling rotation is arranged at one end of the furnace body shell, and a driven rotating gear is arranged at the other end of the furnace body shell. A feeding opening is formed in the side face or one end surface of the furnace body shell, and a smoke exhaust opening is formed in the other end face of the furnace body shell. The smoke exhaust opening is in non-contact connection with a flue. One or more bottom blowing air holes and one or more flash spraying nozzles are arranged on the furnace body shell. The bottom blowing air holes and the flash spraying nozzles penetrate the furnace body shell and are communicated with the inside of the furnace cavity. The flash spraying nozzles are arranged at the feeding opening of the furnace body. By the adoption of the technical scheme, the metallurgical reaction process can be accelerated, the volatilization smelting oxidation reaction effect of the antimony ore blast furnace is strengthened, the productivity is effectively improved, the energy consumption is reduced, the economic technical index is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a smelting converter for antimony ore bottom-blown flash mixed molten pool. Background technique [0002] Traditional antimony ore rough smelting processes are popularly applied in vertical shaft furnace volatilization roasting, open hearth bottom blowing volatilization roasting, and blast furnace volatilization smelting. Among them, vertical well 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 the furnace, and the volatiliz...
