With the deep spiral flow deflector structure, the rotary kiln space can be sufficiently utilized by a material, the material is capable of sufficiently contacting air, the vanadium oxidation reaction is sufficient, the environment-friendly and energy-saving effects are achieved, and the continuous production requirement can be met.
Description
Technical field
The utility model relates to rotary kiln technical field, relates in particular to a kind of constant temperature vanadium oxidation reaction rotary kiln.
Background technology
Containing vanadium gangue, after decarbonation appliance, the temperature of slag is generally more than 850 ℃, and in the slag of this high temperature, 80% v element is Low Valent Vanadium.Low Valent Vanadium, due to less stable, difficult extraction, therefore must make it to be converted to high price vanadium at 750-850 ℃ of temperature.
Existing slag Low Valent Vanadium turns the transfer process of high price vanadium generally to be taked in a plurality of fixedly roasters of outdoor placement the mode of adding a small amount of fuel baking, or adopts the fixing storage of large volume slag storehouse, and interior blowing air makes it to carry out the mode of oxidation reaction.All large and pollute fully haptoreaction of large, high temperature furnace slag and air with upper type floor space, especially cannot realize continuous production.
Utility model content
Technical problem to be solved in the utility model is, for the above-mentioned deficiency of prior art, propose a kind of take up an area little, efficiency of combustion is high, the constant temperature vanadium oxidation reaction rotary kiln of environmental protection.
The technical scheme that the utility model solves its technical problem employing is, a kind of constant temperature vanadium oxidation reaction rotary kiln is proposed, it comprises cylindrical shell, is arranged at deep helical flow deflector and the circumferential scraper plate of inner barrel, is arranged at the material inlet of cylindrical shell one side and the material outlet that is arranged at cylindrical shell opposite side, described material inlet is connected with gangue decarburization equipment, and described material outlet is connected with slag cooler; Described circumferential scraper plate is arranged between adjacent deep helical flow deflector.
Further, the quantity interval that is arranged at the circumferential scraper plate between adjacent deep helical flow deflector equates.
Further, described cylinder inboard wall is also provided with heat-insulation layer and flame retardant coating, and heat-insulation layer is coated on flame retardant coating outer wall.
The utility model, by adopting deep helical flow deflector structure, makes material can make full use of rotary kiln space, and material fully contacts with air, and vanadium oxidation reaction is abundant, environmental protection and energy saving, can meet continuous production requirement.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic of constant temperature vanadium oxidation reaction rotary kiln in the utility model one embodiment;
Fig. 2 is A-A cutaway view in Fig. 1.
The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
Please refer to Fig. 1, Fig. 2, the utility model constant temperature vanadium oxidation reaction rotary kiln, it comprises cylindrical shell 1, be arranged at the deep helical flow deflector 2 of cylindrical shell 1 inside and circumferentially scraper plate 3, the material outlet 5 that is arranged at the material inlet 4 of cylindrical shell one side and is arranged at cylindrical shell opposite side, described material inlet 4 is connected with gangue decarburization equipment, and described material outlet 5 is connected with slag cooler; Described circumferential scraper plate 3 is arranged between deep helical flow deflector 2 adjacent blades.
The high temperature that gangue decarburization equipment is discharged enters rotary kiln oxidation reaction containing vanadium gangue by material inlet 4, then by material outlet 5, is expelled to slag cooler.Containing the required air of vanadium gangue oxidation reaction, from contrary direction, enter rotary kiln, also containing the required air of vanadium gangue oxidation reaction, from material outlet 5, enter rotary kiln, from material inlet 4, discharge.
The utility model is used rotary kiln as the main equipment of vanadium oxidation reaction, has opened up the frontier of high temperature sludge alum oxidation consersion unit after gangue decarburization.When the cylindrical shell 1 of rotary kiln rotates, high-temperature material slowly moves forward between deep helical flow deflector 2, enters slag cooler cooling, thereby can realize continuous production after the interior oxidation reaction of cylindrical shell 1 from material outlet 4.
In addition, deep helical flow deflector structure of the present utility model can make full use of the inner space of rotary kiln, high temperature can reach 40% left and right of cylindrical shell volume containing the loading of vanadium gangue filling cylindrical shell, this loading has improved production capacity on the one hand, has also guaranteed on the other hand the air supply of cylindrical shell 1 interior abundance.
Further, in order to guarantee that the high temperature in cylindrical shell 1 can fully contact with air containing vanadium gangue, is also provided with circumferential scraper plate 3 between adjacent deep helical flow deflector.Circumferentially scraper plate 3 can automatically stir containing vanadium gangue high temperature when barrel body rotation, makes high temperature contain vanadium gangue and the abundant oxidation reaction of air.Preferably, the quantity interval that is arranged at the circumferential scraper plate between adjacent deep helical flow deflector equates, be so arranged so that circumferential scraper plate for material to stir effect more remarkable.
In addition, because v element oxidizing reaction temperature General Requirements is controlled within the scope of 750-850 ℃, the more than 850 ℃ high temperature of discharging from gangue decarburization equipment contains vanadium gangue after material inlet enters rotary kiln, must strictly control its time stopping and temperature drop gradient in rotary kiln, for reaching above-mentioned effect, the cylinder inboard wall of the utility model constant temperature vanadium oxidation reaction rotary kiln is also provided with heat-insulation layer 6 and flame retardant coating 7, and heat-insulation layer is coated on flame retardant coating 7 outer walls.Heat-insulation layer 6 and flame retardant coating 7 guarantee that material outlet temperature is greater than 750 ℃.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
