Abstract
The utility model relates to a calcine burning furnace with developments of fluidization mode calcination material, including gas heating furnace, cyclone and furnace body, the furnace body communicates with each other with gas heating furnace through the pipeline that has the feed inlet, and the suction fan is linked together through pipeline and furnace body export and cyclone's import, just has the awl cylinder that an upper portion becomes the cone, the lower part becomes the cylinder to furnace mouth department in the furnace body. Under the action of the cone column, the materials and the high-temperature gas are directly collided, dispersed and mixed in the furnace body, the mass and heat transfer process is strengthened, and quick chemical reaction is carried out.
Description
The utility model relates to a kind of equipment that solid material is calcined, and relates in particular to a kind of dynamic calcining stove with fluidization mode calcining materials.
Static calcining and half dynamic calcining are generally adopted in the calcining of granular material, and static calcining and half dynamic calcining are in the course of the work, owing to material and thermal medium can not fully exchange, thereby cause energy waste big, calcination efficiency is low, defectives such as unstable product quality.Especially for half dynamic calcining equipment, also relate to mechanical driving part, so structure is complicated more, maintenance is all inconvenient.At above-mentioned defective, a kind of dynamic calcining stove is arranged at present, this calcining furnace mainly is made of body of heater, gas-solid mixing homogenizer, gas heater, gas-solid separator and air-introduced machine, makes granular material carry out quick mass-and heat-transfer process with high-temperature gas in body of heater, has improved calcination efficiency.But this kind calcining furnace is in calcination process, because material must be that homogenizing enters in the body of heater after the granularity of regulation again in the gas-solid blender, therefore enter in the body of heater for also not carried secretly to the material of designated size by homogenizing, in stove, under the drive of high velocity air, carry out heat exchange, but because of raw meal particle size bigger, under the inadequate situation of heat exchange, also can from calcining furnace, leave away fast, therefore produce giving birth to of material and burnt phenomenon, influence the quality of calcination product with air-flow.
The purpose of this utility model provides a kind of simple in structure, material can with direct uniform mixing of the high-temperature gas in the stove, heat exchange is abundant, and can guarantee the dynamic calcining stove of calcination product quality.
The utility model is that the technical scheme that achieves the above object is: a kind of dynamic calcining stove, comprise gas heating stove, cyclone separator and body of heater, body of heater communicates with gas heating stove by the pipeline that has charging aperture, induced-draught fan is connected by the import of pipeline with body of heater outlet and cyclone separator, it is characterized in that: have a top to become cone, bottom to become the awl cylinder of cylinder over against the fire door place in the body of heater.
The central axes of the central axis of body of heater and awl cylinder, and the column diameter of awl cylinder is 0.6～0.8 times of body of heater internal diameter, and the height of cylinder is 0.5～1.5 times of body of heater internal diameter, and the cone angle of cone is in 60 °～120 ° scopes.
The utility model adopts the advantage of technique scheme to be: because granular material directly enters in the calcining furnace after adding, cancelled gas-solid mixing homogenizer from charge door, further simplified the structure of equipment.When granular material and high-temperature gas together enter calcining furnace, because under the awl cylinder effect in body of heater, strong collision at first takes place with the awl cylinder in material and high-temperature gas, granular material and the high temperature gas flow concentrated have been disperseed, granular material directly mixes in body of heater with high-temperature gas, make gas-solid two-phase and stream, high velocity air further drives material again and carries out strong disturbance, collision, mix again, material can fully be suspended in the hot gas, enhancing mass and heat transfer process and carry out fast chemical reaction, so heat exchange is abundant, the calcination efficiency height, thermal energy consumption is low.Simultaneously, because the effect of awl cylinder, can suitably prolong the calcination time of material in stove, material can not produce burning, and can guarantee that again material does not have burning, therefore treat that the fully outstanding prisoner of calcining materials and high-temperature gas mixes, moment is finished the calcination process of material in high quality in fluidized state, improves product quality.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Dynamic calcining stove of the present utility model shown in Fig. 1～2 comprises gas heating stove 1, cyclone separator 8, body of heater 5 and induced-draught fan 1.Explosion-proof diaphragm 13 is equipped with at the top of body of heater 5, and as shown in Figure 2, there is tangential inlet 14 at the fire door place of body of heater 5, makes the gas-solid two-phase can rotate rising in body of heater 5.The fire door of body of heater 5 is connected by the outlet of pipeline 4 with gas heating stove 1, and pipeline 4 is provided with charging aperture 3, granular material is collided in stove with high-temperature gas mix.Be to reduce the putty phenomenon at charging aperture 3 places, there is charging aperture 3 at the middle part of pipeline 4, and its two ends respectively flaring become a Venturi tube.Induced-draught fan 1 links to each other with the outlet of body of heater 5 and the import of cyclone separator 8 by pipeline 10, as shown in Figure 1 can be according to the degree of being refined into of material, cyclone separator 8 can be made as multistage, body of heater 5 inner bottom parts have a top to be cone over against the fire door place, the bottom is the awl cylinder 6 of cylinder, the central axis of body of heater 5 and the central axes of boring cylinder 6, the column diameter of awl cylinder is 0.6～0.8 times of body of heater internal diameter, the height of cylinder is 0.5～1.5 times of body of heater 5 internal diameters, the cone angle of cone is in 60 °～120 ° scopes, can be according to different materials and required requirement, select above-mentioned technical parameter, therefore high-speed gas and granular material carry out strong collision with awl cylinder 6 in body of heater 5, make the gas-solid two-phase abundant in stove, moment mixes, and carries out heat and mass and chemical reaction.
In order to reduce the thermal deformation of gas heating stove 1 output, between pipeline 4 and gas heating stove 1, expansion pipe 2 is housed also.
For further prolonging the time of material in body of heater 5, increase the calcination time of material, spinning disk 12 also is equipped with on the top in the body of heater 5.
During the utility model work, the high-temperature gas that gas heating stove 1 burning produces enters in the body of heater 5 by pipeline 4, simultaneously powdery is treated that the material of roasting sends into pipeline 4, material and hot gas together enter rotation rising in the dynamic body of heater 5 of eddy flow, because powder tablet surface area is big, and fully be suspended in the hot gas, cause mass-and heat-transfer and chemical reaction velocity to be exceedingly fast, moment promptly can be finished the calcination process of granular material in high quality, then, hot gas and material enter cyclone separator 8 together and carry out dedusting, finished product materials is discharged through the discharge device of cyclone separator 8, the pack packing, hot gas is then recycled by pipeline, and entire work process is by electrical control cubicles 9 controls.
