Problems solved by technology

Disadvantages: First, the tuyere is washed by the high-speed particle flow of wind coal, which causes serious wear and short life; second, because the steam produced by the waste heat of the flue gas is discontinuous and has large peak and trough fluctuations due to intermittent operation, it is not conducive to utilization ; The third is the need for complex pulverized coal preparation system

Embodiment Construction

[0018] The present invention will be described below in conjunction with accompanying drawing and embodiment

[0019] in accordance with figure 1 , figure 2 The specific implementation of the tunnel-type adjustable slag outlet continuous fuming furnace of the present invention is described below.

[0020] The tunnel-type adjustable slag port continuous fuming furnace disclosed in this embodiment includes a furnace 8, a tuyere 2, a feed port 1, a slag discharge port 7, and a straight-up flue 4, wherein the furnace 8 is designed as a tunnel structure; the tuyere 2 It is arranged on both sides of the bottom of the furnace 8. The feed port 1 and the slag discharge port 7 are placed at the first and last ends of the furnace. The height of the top of the furnace from the feed port 1 to the slag discharge port 7 is designed to rise in steps; 4 is arranged on the top of the slag discharge end 6 of the furnace; the height of the slag discharge port 7 is adjustable.

Abstract

The invention provides a tunnel type slag-hole-adjustable continuous fuming furnace. The furnace comprises a hearth, wind holes, a feeding hole, a slag discharging hole and a vertical-lift flue, wherein the hearth is designed into a tunnel type structure; the wind holes are formed in two sides of the bottom of the hearth, the feeding hole and the slag discharging hole are respectively formed in the head and tail ends of the hearth, and the heights of the tops of the hearth from the feeding hole to the slag discharging hole are designed to be increased in a step manner; the vertical-lift flue is arranged at the top of a slag discharging end of the hearth; the height of the slag discharging hole can be adjusted. The tunnel type slag-hole-adjustable continuous fuming furnace has the advantages that the production is continuous, process parameters are easy to control, and the steam produced by the waste heat of the flue gas is continuous and stable; a pulverized coal preparation system is not needed.

Description

technical field [0001] The invention relates to a slag fuming recovery device in the field of nonferrous metallurgy, in particular to a tunnel-type continuous fuming furnace with adjustable slag outlet. Background technique [0002] Fuming furnaces are widely used in the treatment of various slags in non-ferrous metallurgical enterprises, especially the treatment of lead-zinc slag. [0003] The operation process of the traditional fuming furnace is intermittent operation, using pulverized coal as the reducing agent, and pulverized coal and wind are blown into the furnace through the tuyere together. Disadvantages: First, the tuyere is washed by the high-speed particle flow of wind coal, which causes serious wear and short life; second, because the steam produced by the waste heat of the flue gas is discontinuous and has large peak and trough fluctuations due to intermittent operation, it is not conducive to utilization ; The third is the need for complex pulverized coal pre...
