Abstract
The utility model is an energy-saving magnesium metal thermal reduction furnace, with the combustion chamber arranged at one side of internal part of the furnace body. An upright partition is arranged at one side of the combustion chamber close to the reduction tank, with clearance left between the top of the partition and the furnace top. In addition, the top of the combustion chamber is provided with an arch wall, one side of which abuts against the upright partition and the other side is provided with a clearance to the side wall of the furnace body. Furthermore, compared with the normal outlet, the outlet of the smoke drain inside the furnace body is half-sized to make the coal burn sufficiently, raise the temperature inside the furnace body and reduce the dust and exhaust pollution.
Description
Affiliated technical field
The utility model belongs to a kind of reduction furnace of hot reducing method production MAGNESIUM METAL, is a kind of with the coal-fired modified version hearth type reduction that carries out magnesium metal reduction specifically.
Background technology
Hot reducing method production MAGNESIUM METAL mainly is divided into two types at home at present, and a kind of is the reduction furnace of gas heating, production process cleaning, stable, but need stable gas supply, cost is higher.Another kind is the metal magnesium reduction furnace that adopts the more general direct combustion heat supplying of coal, and this reduction furnace flue dust is big, heat utilization efficiency is low, and coal consumption is higher.Its structure is: in both sides, body of heater outside four combustion chambers are set respectively, the hot gas of combustion chamber enters in the body of heater by the passage on the side wall, and waste gas enters the chimney discharge by the negative pressure smoke-uptake of bottom of furnace body.Its main drawback is that coal combustion is insufficient, and thermosteresis is bigger.
Summary of the invention
The utility model is exactly a kind of energy-conservation MAGNESIUM METAL thermal reduction furnace at the shortcoming design of prior art, by the improvement to the combustion chamber, makes coal-fired fully burning, improves the intravital temperature of stove, reduces smoke contamination, reduces energy consumption.
The technical scheme that its technical problem that solves the utility model adopts is: design a kind of energy-conservation MAGNESIUM METAL thermal reduction furnace, by body of heater, furnace roof, smoke-uptake, combustion chamber be contained in the intravital reduction of stove and jar form, the combustion chamber is arranged on the inner side of body of heater, the combustion chamber is provided with vertical partition wall by reduction jar one side, leave the gap between partition wall top and the furnace roof, clearance height is about 0.4～0.8 meter.Top of combustion chamber is provided with the arch revetment, and arch revetment one end leaves the gap near vertical partition wall between the other end and the body of heater side wall, and clearance distance is about 0.2～0.5 meter, and the arch revetment is lower than it by body of heater side wall one end by vertical partition wall one end.Leave on the body of heater side wall except that cinder notch and baffle plate; The more common outlet of outlet of smoke-uptake is dwindled and is made an appointment with half in the body of heater; The combustion chamber is by the blower fan blast roasting.
The beneficial effects of the utility model are, the combustion chamber is placed on the temperature of combustion that the combustion chamber can be improved in body of heater inside, arch revetment, the vertical partition wall of top of combustion chamber being set and dwindling the smoke-uptake outlet area all is in order to make coal-fired fully burning, improve the intravital temperature of stove, reduce dust and exhaust emission.

Embodiment
Make energy-conservation MAGNESIUM METAL thermal reduction furnace, two combustion chambers 9 are arranged on side wall 7 limits of the inner side of body of heater, Yi Bian combustion chamber 9 is provided with vertical partition wall 3 by reduction jar 1, leaving between partition wall 3 tops and the furnace roof 2 highly is 0.5 meter gap.9 tops, combustion chamber are provided with arch revetment 4, and arch revetment 4 one ends leave between the other end and the body of heater side wall 7 apart from the gap that is 0.3 meter near vertical partition wall 3, and arch revetment 4 is lower than it by body of heater side wall 7 one ends by vertical partition wall 3 one ends.Leave on the body of heater side wall 7 except that cinder notch 5 and baffle plate 6; The outlet area of body of heater inner bottom part smoke-uptake 8 is about 0.1 * 0.1 meter; Combustion chamber 9 usefulness blower fans, 10 blast roastings.The arch revetment 4 at 9 tops, combustion chamber, vertical partition wall 3 and to dwindle the smoke-uptake outlet area all be in order to make coal-fired fully burning, to improve the intravital temperature of stove, reducing dust and exhaust emission.
Claims (2)
1. energy-conservation MAGNESIUM METAL thermal reduction furnace, by body of heater, furnace roof, smoke-uptake, combustion chamber be contained in the intravital reduction of stove and jar form, it is characterized in that: the combustion chamber is arranged on the inner side of body of heater, Yi Bian the combustion chamber is provided with vertical partition wall by the reduction jar, leaves the gap between partition wall top and the furnace roof; Top of combustion chamber is provided with the arch revetment, and arch revetment one end leaves the gap near vertical partition wall between the other end and the body of heater side wall; Leave on the body of heater side wall except that cinder notch and baffle plate; The more common outlet of outlet of smoke-uptake is dwindled and is made an appointment with half in the body of heater.
