Abstract
The utility model provides a horizontal tank type reducing furnace for magnesium smelting by a hot reducing method. The horizontal cylinder type reducing furnace is provided with upper and lower two layers of tubular reaction tanks (1), and the tank mouths (8) of the upper and the lower reaction tanks are respectively exposed outside two side furnace walls (2). Each of the tubular reaction tank (1) is supported by a support seat (6) fixed on a furnace bottom (5); a burner (3) is arranged on both side furnace walls (2) arranged above the reaction tanks (1) or on a furnace top (4); a fume outlet (7) is arranged on the furnace bottom (5). The reducing furnace has high yield, low energy consumption, simple structure, small equipment investment of specific yield, small area occupation, and convenient technological operation.
Description
The utility model relates to a kind of cross pot type reduction furnace of smelting magnesium by thermal reduction process, is specially adapted to the cross pot type reduction furnace of magnesium-smelting silicothermic process.
Smelting magnesium by thermal reduction process is one of production method of magnesium, and wherein silicothermic process ［ claims Pidgeon process (pidgeon) again ］ in industrial more employing.Magnesium-smelting silicothermic process technology: in retort, with ferrosilicon vacuum (6～13Pa) and the condition of high temperature (1150～1200 ℃) under reduce calcined dolomite, directly produce magnesium.
The major equipment of magnesium-smelting silicothermic process is a reduction furnace, mostly uses Canadian Pidgeon process reduction furnace at present both at home and abroad.This stove is equipped with several retort that forms a line, and lies on the interior knee wall of reduction furnace, and this reduction furnace can heat periodic production crystallization magnesium with liquid or geseous fuel." metallurgy of megnesium " that metallurgical industry press publishes done introduction in this.But the problem that adopts this reduction furnace to exist is: the retort quantity of being installed is few, product magnesium amount is low, and furnace thermal efficiency is low, energy consumption is high, and the facility investment of unit output is big, occupation of land is many, thus the product cost height.
The purpose of this utility model provides a kind of cross pot type reduction furnace of magnesium-smelting silicothermic process, and it can double output under the situation that does not increase the body of heater volume.
For achieving the above object, take in reduction furnace, to install the measure of two-layer retort down.Be exactly that the tubular reactor jar is inserted burner hearth from the both sides furnace wall respectively, it is two-layer up and down that retort is lined up in stove, and the retort jar mouth of levels is exposed at respectively outside the furnace wall of both sides, and above-mentioned retort is by the seat supports that is fixed on furnace bottom; Burner is installed in stove side wall retort top, or flat flame burner is installed in furnace roof; Exhanst gas outlet is located at furnace bottom.
The reduction furnace that the utility model provides, compared with prior art the advantage that is had is: (1) is owing to adopt double-deck retort structure, do not increase at reduction furnace under the situation of volume, the retort quantity expansion of its installation is twice, thereby has improved output and heat energy utilization rate; (2) be located at outside the furnace wall of both sides because of the retort jar mouth branch of levels again,, also be convenient to production operation so be convenient to pipe connection between retort and vacuum pump; (3) simple in structure, be convenient to construction and maintenance; (4) facility investment of unit output and floor space are few; (5) product cost is low.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the cross-sectional synoptic diagram of looking of the cross pot type reduction furnace of the utility model smelting magnesium by thermal reduction process.
As shown in Figure 1: body of heater is made up of furnace wall (2), furnace roof (4) and furnace bottom (5).Several tubular reactor jars (1) of levels insert burner hearth from both sides furnace wall (2) respectively, and the jar mouthful (8) of the retort of this levels (1) is exposed at respectively outside the both sides furnace wall (2), and this jar mouth (8) is as the dress discharge port; Also the tubular reactor jar (1) of levels burner hearth be can be inserted from a wing furnace wall (2), but pipe connection and production operation between retort (1) and vacuum pump are not easy to.All retort (1) support by the bearing (6) that is fixed on the furnace bottom (5).Body of heater and bearing (6) are made with refractory materials, and retort (1) is made of heat-resisting alloy steel.Reduction furnace can also can adopt several burners (3) heat supply on the both sides furnace wall (2) that is installed in retort (1) top with several flat flame burners (3) heat supply that is installed in furnace roof (4).When definite burner (3) and upper strata retort (1) spacing, directly do not burn its retort (1) surface with the flame of burner (3) ejection and be advisable.When adopting side wall (2) burner (3) heat supply, preferably burner (3) is divided to be located at both sides furnace wall (2), and face burner (3) dislocation mutually and arrange.All burners (3) should be evenly distributed on furnace roof (4) or the furnace wall (2), so that furnace temperature is even.Exhanst gas outlet (7) is located at furnace bottom (5) equably.This reduction furnace can be used coal gas, light oil or heavy oil combustion heating, and Control for Kiln Temperature is at 1150～1200 ℃.
Claims (4)
1, a kind of cross pot type reduction furnace of smelting magnesium by thermal reduction process, body of heater is made up of furnace wall (2), furnace roof (4) and furnace bottom (5), tubular reactor jar (1) is disposed across on the bearing (6) on the furnace bottom (5), exhanst gas outlet (7) is located at furnace bottom (5), it is characterized in that: said tubular reactor jar (1) is lined up two-layer up and down in stove, and burner (3) is installed in furnace roof (4).
2, reduction furnace according to claim 1 is characterized in that: the jar mouthful (8) of the tubular reactor jar (1) of this levels is exposed at respectively outside the both sides furnace wall (2).
3, reduction furnace according to claim 1 is characterized in that: the burner (3) that is installed in furnace roof (4) is a flat flame burner.
4, reduction furnace according to claim 1 is characterized in that: burner (3) is installed on the furnace wall (2) of tubular reactor jar (1) top.
