With reference to figure 1 and Fig. 2 the melting furnace 100 according to the utility model embodiment is described below.Melting furnace according to the utility model embodiment is used to melt vanadic anhydride, therefore, also can be called the vanadic anhydride melting furnace.
Vanadic anhydride melting furnace 100 according to an embodiment of the utility model comprises body of heater 101, baffle plate 103 and burner 102.Body of heater 101 for example comprises furnace shell and is arranged on refractory material or the heat-resisting steel sheet and plate 1014 in the furnace shell.Limit furnace chamber in the 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 the said furnace chamber said furnace chamber is divided into melting chamber R and expansion chamber C; The upper end of baffle plate 103 link to each other with the roof of said furnace chamber and the roof of the lower end of baffle plate 103 and said furnace chamber at a distance of preset distance; In other words; The top of melting chamber R and expansion chamber C separates through partition wall 103, and the bottom of melting chamber R and expansion chamber C is communicated with.
Vanadic anhydride melting furnace 100 according to the utility model embodiment can be used for the fusing of vanadic anhydride pulvis with preparation vanadic anhydride tablet; Thereby the fusing of vanadic anhydride and drying, decomposition, oxidation in the vanadium leaching process are separated, reduced energy consumption.And; Because through baffle plate 103 inner chamber of melting furnace has been divided into melting chamber R and expansion chamber C, being melted in the melting chamber R of vanadic anhydride pulvis carried out, the vanadic anhydride entering expansion chamber C sedimentation after the fusing; Discharge through melt outlet 1013 at last; Therefore unfused vanadic anhydride pulvis and the vanadic anhydride droplet sedimentation in expansion chamber C that is contained in the fusing in the flue gas have reduced vanadic anhydride pulvis and the content of vanadic anhydride droplet in the flue gas that exhanst gas outlet 1012 discharges, have improved the rate of recovery of vanadium; Reduce pollution, improved operating environment.
In some embodiment of the utility model; Charge door 1011 is positioned at the top of melting chamber R; Exhanst gas outlet 1012 is spaced apart with charge door 1011 along vertical (left and right directions among Fig. 1) of body of heater 101, and melt outlet 1013 is arranged in the end near exhanst gas outlet 1012 (left end of Fig. 1) of body of heater 101.Through with exhanst gas outlet 1012 and charge door 1011 spaced apart settings, make fusing and sedimentation influence each other and reduce, further reduced the content of the vanadic anhydride droplet of vanadic anhydride pulvis and fusing in the flue gas.
As illustrated in fig. 1 and 2, preferably, the height of melting chamber R can melt greater than the height of expansion chamber C thus better.Burner 102 can for example illustrate two for a plurality of and spaced apart on above-below direction in Fig. 1 and Fig. 2, further improve the effect of fusing.
In some preferred embodiments of the utility model; Baffle plate 103 is a plurality of; A plurality of baffle plates 103 are longitudinally-spaced expansion chamber C is divided into a plurality of sub-expansion chambers, as shown in Figure 1 along body of heater 101, in body of heater 101, are provided with two baffle plates 103; Thereby expansion chamber C is divided into two sub-expansion chamber C1, C2.Exhanst gas outlet 1012 is located on the roof of melting chamber R expansion chamber C2 farthest, and on the roof of the sub-expansion chamber C1 adjacent with melting chamber R, is provided with auxiliary burning nozzle 104.Through expansion chamber C being divided into a plurality of sub-expansion chambers, can carry out multistage sedimentation, further improved effect of settling, the vanadic anhydride pulvis in the reduction flue gas and the content of vanadic anhydride droplet reduce and pollute, and improve operating environment.Through auxiliary burning nozzle 104 is set, can the unfused vanadic anhydride pulvis that get in the sub-expansion chamber C1 be melted once more, improved the fusing effect, reduced the amount of vanadic anhydride pulvis in the flue gas.
Baffle plate 103 for example can be processed by heat-resisting steel sheet and plate, makes thus simply, and it is convenient to change.
As illustrated in fig. 1 and 2; Emission effect for the vanadic anhydride that improves fusing; The bottom surface of furnace chamber is downward-sloping gradually along the direction from melting chamber R to expansion chamber C in the vertical; And can on the bottom surface of furnace chamber, be provided with the chase 1014 that extends longitudinally, the left end of chase 1014 links to each other with melt outlet 1013, has made things convenient for the discharge of melt (vanadic anhydride of fusion).
Below the simple operation of describing according to the vanadic anhydride melting furnace 100 of the utility model embodiment.
In melting chamber R, spray into coal gas and oxygen to heating in the melting chamber R through burner 1012; For example be heated to 800-850 degree centigrade temperature; The vanadic anhydride pulvis is joined in the melting chamber R from charge door 1011, be heated fusing in the process that the vanadic anhydride pulvis descends in melting chamber R.
The vanadic anhydride of fusing flows to 1013 discharges of melt outlet along the bottom surface of furnace chamber, and melt outlet 1013 can link to each other with pelleter and carry out film-making, thereby obtains the vanadic anhydride tablet.
Flue gas and unfused vanadic anhydride pulvis and the vanadic anhydride droplet that is contained in the fusing in the flue gas get in the sub-expansion chamber C1 from the slit of melting chamber R below the baffle plate of the rightmost side; In sub-expansion chamber C1, spray coal gas and oxygen through auxiliary burning nozzle 104; Thereby unfused vanadic anhydride pulvis is carried out the assistant heating fusing, and the vanadic anhydride melt-flow of fusing is discharged to melt outlet 1013 once more.
Flue gas and remaining a small amount of vanadic anhydride pulvis and be contained in vanadic anhydride droplet in the flue gas and get into sub-expansion chamber C2 from the slit of sub-expansion chamber C1 through next baffle plate 103 below and carry out sedimentation once more, flue gas is from exhanst gas outlet 1012 discharges then.
Therefore,, reduced pollution, improved operating environment through repeatedly sedimentation and the auxiliary smoke content that has reduced from the flue gas that exhanst gas outlet 1012 is discharged that melts.And, in the vanadic anhydride melting furnace of the utility model embodiment, only carry out the heat fused of vanadic anhydride pulvis, for example temperature can be controlled in 800-850 degree centigrade the scope, has reduced energy consumption.
In the description of this specification, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means the concrete characteristic, structure, material or the characteristics that combine this embodiment or example to describe and is contained among at least one embodiment or example of the utility model.In this manual, the schematic statement to above-mentioned term not necessarily refers to identical embodiment or example.And concrete characteristic, structure, material or the characteristics of description can combine with suitable manner in any one or more embodiment or example.
Although illustrated and described the embodiment of the utility model; Those having ordinary skill in the art will appreciate that: under the situation of principle that does not break away from the utility model and aim, can carry out multiple variation, modification, replacement and modification to these embodiment, the scope of the utility model is limited claim and equivalent thereof.
