Description
Technical field
The utility model is related to magnesium metal smelt field, more particularly to a kind of refining magnesium furnace for collecting flue gas.
Background technology
The production of magnesium metal mainly has electrolysis and ferrosilicon process (Pidgeon process, Pidgeon).Because production of magnesium by pidgeonprocess technique stream
Journey and equipment are simpler, and small investment of founding the factory, cost are relatively low, and production scale flexibly, the features such as the purity of finished product magnesium is high, becomes China
The important method of production magnesium metal.The crude magnesium obtained in reduction furnace using production of magnesium by pidgeonprocess technique is because impurity content is high, structure
Loose, easily corrode, inconvenience storage.Impurity therein is also harmful to manufacturing magnesium alloy and other products.So necessary
Essence is carried out to Crystalline Magnesium
Refining, removes impurity and is cast into magnesium ingot.The quality of refining directly influences the quality of magnesium finished product and magnesium products life
The index of product.
The hot method magnesium refining of China substantially adopts flux method, i.e. flux first after the refining copple stove fusing of refining magnesium furnace,
Self-produced crude magnesium is directly added into refining copple and is refined, and also needs to add fire extinguishing flux in refining process, produces chlorine in refining process
The corrosive fumes such as compound, oxide and sulfide, the flue gas that most of magnesium factory produces through processing, are not directly distributed in car
Between or be discharged into outside workshop, not only polluted environment but endanger workman healthy.
In consideration of it, being necessary to design a kind of refining magnesium furnace for collecting flue gas to solve the above problems.
Utility model content
The purpose of this utility model is to provide a kind of magnesium essence that can be collected the flue gas high efficiency produced in refining process
Furnace, the flue gas of collection are conducive to concentrating through environment friendly system process, realize that environmental protection is produced.
For reaching above-mentioned purpose, the utility model provides following technical scheme：A kind of refining magnesium furnace for collecting flue gas,
For the remelting refining of magnesium metal, including body of heater, the crucible being positioned in body of heater and the bell being placed on body of heater, on the crucible
Side is provided with gas collector, and the bell is located at the top of gas collector, and the refining magnesium furnace also includes the air inducing being connected with gas collector
System.
Further, the gas collector includes the circular body with cavity and the blast pipe through cavity, described
Some air admission holes are opened up on body.
Further, the area of the air admission hole increases as the distance of air admission hole and blast pipe increases.
Further, the gas collector is embedded is installed in the body of heater.
Further, the bell is circle, is made up of the cover plate split of two semicircle shapes.
Further, portion and depressed part are conformed between the cover plate and cover plate, and the jut and depressed part are mutual
Coordinate to increase the sealing between cover plate and cover plate.
Further, the induced draught system includes air-introduced machine and the airduct being connected between air-introduced machine and gas collector.
Compared with prior art, the utility model refining magnesium furnace collects magnesium melting by arranging with the gas collector above crucible
The corrosive fumes such as the chloride of the protection that process is produced, sulfur dioxide, being delivered to flue gas purifying equipment through induced draught system is carried out
Purify, reduce and pollute environment, harmful effect of the minimizing to the healthy and production equipment of workman, and equipment energy saving in running,
Efficiently.

Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described further, is symbol as shown in Figures 1 to 5
Close a kind of refining magnesium furnace 100 of the flue gas collected of remelting refining for magnesium metal of the present utility model.The refining magnesium furnace
100 include body of heater 1, the crucible 2 being positioned in body of heater, bell 3.Gas collector 4 is set above the crucible 2, and body of heater 1 is used for earthenware
Crucible 2 provides thermal source, and crude magnesium flue gas produced by melting in crucible 2 is collected by the gas collector 4, and the gas collector 4 connects air inducing
The flue gas that gas collector 4 is collected is delivered to purification facility (not shown) and is cleaned process by system 5.The bell 3 is in the gas collection
During the top of device 4, prevention or minimizing flue gas are distributed to the outer air of stove from body of heater, flue gas is promoted to be trapped by gas collector 4, so as to
Increase the removal rate of flue gas.
The gas collector 4 includes the circular body 41 with cavity 40 and the blast pipe 42 through cavity 40, described
Body 41 is enclosed and is formed by the side wall 411 and upper sealing plate 412 and lower shrouding 413 of two concentric different-diameters, wherein small diameter
Side wall 411 on open up some air admission holes 4111, the blast pipe 42 connects induced draught system 5, in the swabbing action of induced draught system 5
Under, negative pressure is formed in the cavity 40 of gas collector 4, bigger away from the nearer position negative pressure of blast pipe 42, pump drainage flue gas is faster.In order to equal
The flue gas that even 2 surrounding of pump drainage crucible is produced, the size of the air admission hole 4111 are inconsistent, the area of air admission hole 4111 with
Its increase with the distance of blast pipe 42 and increase, so as to more rapidly, more thorough pump drainage flue gas.
