Below with reference to Fig. 1 and Fig. 2, the melting furnace 100 according to the embodiment of the present invention is described.According to the melting furnace of the embodiment of the present invention for melting vanadic anhydride, therefore, also vanadic anhydride melting furnace can be called.
Vanadic anhydride melting furnace 100 comprises body of heater 101 according to an embodiment of the invention, baffle plate 103, and burner 102.Body of heater 101 such as comprises furnace shell and the refractory material be arranged in furnace shell or heat-resisting steel sheet and plate 1014.Limit furnace chamber in body of heater 101, body of heater 101 has charge door 1011, exhanst gas outlet 1012 and melt outlet 1013.
Baffle plate 103 is arranged in described furnace chamber so that described furnace chamber is divided into melting chamber R and expansion chamber C, the upper end of baffle plate 103 is connected with the roof of described furnace chamber and the roof of the lower end of baffle plate 103 and described furnace chamber preset distance apart, in other words, the top of melting chamber R and expansion chamber C is separated by partition wall 103, and melting chamber R is communicated with the bottom of expansion chamber C.
Burner 102 is arranged on the sidewall of melting chamber R, for burner oil in melting chamber R, thus to from charge door 1011, the vanadic anhydride pulvis joined in melting chamber R heats.Burner 102 is preferably coal gas burner.
May be used for by the fusing of vanadic anhydride pulvis to prepare vanadic anhydride tablet according to the vanadic anhydride melting furnace 100 of the embodiment of the present invention, thus the fusing of vanadic anhydride and the drying in vanadium leaching process, decomposition, oxidation are separated, reduce energy consumption.And, owing to the inner chamber of melting furnace be divide into melting chamber R and expansion chamber C by baffle plate 103, being melted in melting chamber R of vanadic anhydride pulvis is carried out, vanadic anhydride after fusing enters expansion chamber C sedimentation, discharge finally by melt outlet 1013, unfused vanadic anhydride pulvis and be contained in vanadic anhydride droplet sedimentation in expansion chamber C of the fusing in flue gas, because this reducing vanadic anhydride pulvis in flue gas that exhanst gas outlet 1012 discharges and the content of vanadic anhydride droplet, improve the rate of recovery of vanadium, reduce pollution, improve operating environment.
In some embodiments of the invention, charge door 1011 is positioned at the top of melting chamber R, exhanst gas outlet 1012 is spaced apart with charge door 1011 along the longitudinal direction (left and right directions in Fig. 1) of body of heater 101, and melt outlet 1013 is arranged in one end (left end of Fig. 1) of the close exhanst gas outlet 1012 of body of heater 101.By by exhanst gas outlet 1012 and the spaced apart setting of charge door 1011, make fusing and sedimentation affect reduction each other, further reduce the content of the vanadic anhydride droplet of vanadic anhydride pulvis in flue gas and fusing.
As illustrated in fig. 1 and 2, preferably, the height of melting chamber R is greater than the height of expansion chamber C, can melt better thus.Burner 102 can be multiple and spaced apart in the vertical direction, such as, show two in fig. 1 and 2, improves the effect of fusing further.
In preferred embodiments more of the present invention, baffle plate 103 is multiple, longitudinally-spaced so that expansion chamber C is divided into multiple sub-expansion chamber along body of heater 101 of multiple baffle plate 103, as shown in Figure 1, in body of heater 101, be provided with two baffle plates 103, thus expansion chamber C be divided into two sub-expansion chamber C1, C2.Exhanst gas outlet 1012 is located at apart from the roof of melting chamber R expansion chamber C2 farthest, and is provided with auxiliary burning nozzle 104 on the roof of the sub-expansion chamber C1 adjacent with melting chamber R.By expansion chamber C is divided into multiple sub-expansion chamber, can carries out Multistage settling, further increase effect of settling, the vanadic anhydride pulvis in reduction flue gas and the content of vanadic anhydride droplet, reduce and pollute, improve operating environment.By arranging auxiliary burning nozzle 104, can the unfused vanadic anhydride pulvis entered in sub-expansion chamber C1 be melted again, improve fusing effect, reduce the amount of vanadic anhydride pulvis in flue gas.
Baffle plate 103 such as can be made up of heat-resisting steel sheet and plate, manufactures simple thus, and it is convenient to change.
As illustrated in fig. 1 and 2, in order to improve the emission effect of the vanadic anhydride of fusing, the bottom surface of furnace chamber is in the vertical along downward-sloping gradually from melting chamber R to the direction of expansion chamber C, and the chase 1014 extended longitudinally can be provided with on the bottom surface of furnace chamber, the left end of chase 1014 is connected with melt outlet 1013, facilitates the discharge of melt (vanadic anhydride of melting).
The simple operation described according to the vanadic anhydride melting furnace 100 of the embodiment of the present invention below.
In melting chamber R, coal gas is sprayed into and oxygen heats in melting chamber R by burner 1012, such as be heated to the temperature of 800-850 degree Celsius, vanadic anhydride pulvis is joined in melting chamber R from charge door 1011, by heat fused in the process that vanadic anhydride pulvis declines in melting chamber R.
The vanadic anhydride of fusing flows to melt outlet 1013 along the bottom surface of furnace chamber and discharges, and melt outlet 1013 can be connected with pelleter and carry out film-making, thus obtains vanadic anhydride tablet.
Flue gas and unfused vanadic anhydride pulvis and the vanadic anhydride droplet being contained in the fusing in flue gas enter in sub-expansion chamber C1 from melting chamber R by the gap below the baffle plate of the rightmost side, in sub-expansion chamber C1, coal gas and oxygen is sprayed by auxiliary burning nozzle 104, thus auxiliary heating fusing is carried out to unfused vanadic anhydride pulvis, the vanadic anhydride melt again melted flows to melt outlet 1013 and discharges.
A small amount of vanadic anhydride pulvis of flue gas and remnants and the vanadic anhydride droplet be contained in flue gas enter sub-expansion chamber C2 from sub-expansion chamber C1 by the gap below next baffle plate 103 and carry out sedimentation again, and then flue gas is discharged from exhanst gas outlet 1012.
Therefore, reduced the smoke content the flue gas of discharging from exhanst gas outlet 1012 by repeatedly sedimentation and auxiliary fusing, reduce pollution, improve operating environment.Such as, and only carry out the heat fused of vanadic anhydride pulvis in the vanadic anhydride melting furnace of the embodiment of the present invention, temperature can control, in the scope of 800-850 degree Celsius, to reduce energy consumption.
