Antimony ore double-row air pipes chair form water jacket side blowing air blowing volatilization smelting furnace

Abstract

The invention discloses an antimony ore double-row air pipes chair form water jacket side blowing air blowing volatilization smelting furnace. The smelting furnace comprises a furnace body, a water jacket and air pipes, wherein the water jacket is arranged at the bottom of the furnace body and communicating with the inner part of the furnace body, the water jacket comprises an upper water jacket,a middle water jacket and a lower water jacket which are sequentially arranged from top to bottom, the air pipes comprises upper air pipes and lower air pipes, a plurality of upper air pipes which areuniformly arranged at intervals are arranged on the middle water jacket, a plurality of lower air pipes which are uniformly arranged at intervals are arranged on the lower water jacket, communicatingpipes are arranged between the upper air pipes and the lower air pipes, and regulating valves are arranged on the communicating pipes. According to the smelting furnace, the volatilization smelting oxidation process can be effectively enhanced, the productivity is improved, the energy consumption is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to an antimony ore double-row air pipe chair type water jacket side blowing air blast volatilization smelting furnace. 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....

AI Technical Summary

Problems solved by technology

[0003] The antimony blast furnace is a low material column volatilization smelting and oxidation production process. It adopts the side-blown air supply system of the single-row air pipe of the flat-plate furnace belly water jacket. Inhomogeneity, the air supply on both sides of the tuyere area is excessive, and the phenomenon of perforated air flow often occurs, the air supply of the longitudinal centerline material layer belt in the furnace is seriously insufficient, the heart of the chamber is dim or even black, and the relative air supply of the material layer reaction zone is insufficient. , the oxidizing atmosphere is not enough, resulting in poor oxidation effect of volatilization smelting, high output rate of antimony matte, compared with other non-ferrous metal smelting processes, high energy consumption and low production capacity
