Embodiment
The horizontal sealing rotary kiln is a tubular article that constant slope is arranged, and promotes material to flow in rotary kiln by the rotation of kiln.The rotary kiln type of heating can be internal heat type and external-heat.The kiln hood firing system produces a large amount of heat, and heat is passed to material in modes such as the convection current of flame radiation, hot gas, the conduction of kiln brick.Material relies on the gradient of kiln cylinder body and rotation motion forward in kiln of kiln.Rotary kiln is carbonizing apparatus on the one hand, and wherein firing system produces heat; Also be heat transfer equipment simultaneously, the heat that moulded coal absorbs gas carries out carbonization.Also be handling equipment in addition, raw material is transported to discharge end from feed end.And must rationally cooperate between fuel combustion, heat transfer and raw material motion three, just can make heat that fuel combustion produces in time pass to moulded coal in by the time of rotary kiln at moulded coal, arrived high yield, high-quality, low consumed purpose.This method can be regulated time etc. of the velocity of flow of the raw material moulded coal in the sealing bedroom revolution coke oven, the uniformity coefficient of being heated, carbonization by cylinder internal diameter, cylindrical shell length, cylindrical shell gradient, drum speed.Cylindrical shell is the pivoting part that is heated, and kiln head and tail positiver sealing, cylindrical shell are provided with thermometric, pressure measurement and sampling unit.Rotary kiln is strong to adaptability to raw material, can be difform moulded coal.For example the shape of moulded coal can be spheroid, right cylinder or Polygons etc.
When moulded coal moved in kiln, the mode of motion of moulded coal had periodic variation, or was embedded in bed of material the inside and moves upward with kiln, or to bed of material surface and settle out.But only in the process that raw material lands along upper layer, it could advance along the kiln length direction.Various moving conditions just to the influence of raw material moulded coal stacking factor, must be noted the influence of central angle.If in kiln, keep certain stacking factor, the rotating speed of kiln and rate of feeding are worked in coordination, and keep certain proportion; Can improve output, quality, the stabilization of thermostatic system.
As shown in Figure 1, a kind of device that utilizes the horizontal revolving kiln to produce formed coke, this device comprises: the first horizontal revolving kiln device 3, combustion unit 1, moulded coal input unit 2 and refrigerating unit 5, it is characterized in that: combustion unit 1 is connected with the discharge end a side of the first horizontal revolving kiln device 3, and moulded coal input unit 2 is connected with the b side of the first horizontal revolving kiln device 3, and refrigerating unit 5 is connected with the b side of the first horizontal revolving kiln device 3.The second horizontal revolving kiln device 4 and the first horizontal revolving kiln device 3 are tightly connected, and the second horizontal revolving kiln device 4 is connected with refrigerating unit 5.Wherein the shape of rotary kiln can be that round shape is conical or oval, type coal shape after the moulding can be spherical or cylindric olive-shaped or polygon-shaped etc., and method of cooling can adopt water quenching or dry coke quenching to cool off, the type of heating of rotary kiln can be internal heating or outer heating, and in the first horizontal revolving kiln device 3, be divided into preheating and two stages of carbonization at moulded coal, regulate the velocity of flow of the raw material moulded coal in the sealing bedroom revolution coke oven and the uniformity coefficient of being heated by cylinder internal diameter, cylindrical shell length, cylindrical shell gradient, drum speed.
As shown in Figure 2, the first horizontal revolving kiln device 3 is directly got rid of finished product 6 by refrigerating unit 5 cooling backs, and this device has omitted the second horizontal revolving kiln device 4, and those skilled in the art can realize the technical solution of the utility model equally according to Fig. 2.
As shown in Figure 3, the first horizontal revolving kiln device 3 combines with vertical retort or traditional cokery, the first horizontal revolving kiln device 3 as independent primary heater unit, vertical retort as carbonization and refrigerating unit or traditional cokery as carbonizing plant.Combustion unit 1 is connected with the discharge end a side of the first horizontal revolving kiln device 3, and moulded coal input unit 2 is connected with the b side of the first horizontal revolving kiln device 3, and the first horizontal revolving kiln device 3 is connected with vertical retort or traditional cokery.
The advantage of scheme as shown in Figure 3:
1, the horizontal revolving kiln has solved problems such as moulded coal is hot sticky in the vertical retort carbonization process, heat is broken as primary heater unit.
2, vertical retort can utilize heat energy more fully as carbonizing plant.Because during horizontal revolving kiln addition type coal, the shared volume of moulded coal is between 8 percent of whole kiln cumulative volume～25 percent in the kiln.If so utilize rotary kiln as preheating, carbonizing plant separately, it is energy-conservation to be not so good as this bonded mode.
3, vertical retort can fill up moulded coal in the stove when carbonization, so improved the output of charring furnace greatly by this combination.
4, in conjunction with traditional cokery, can be transformation to present cokery, can save cost like this.Concerning existing mechanical coke factory, use coking of shaping coal, lower the usage quantity of coking coal, thereby reduced raw materials cost.
Equally, realize that the cooling back discharges finished products 6 and can realize the utility model too if change refrigerating unit 5 into other allied equipments such as vertical furnace.The utility model can also be the rotary kiln device separately as refrigerating unit or primary heater unit.
Embodiment of the present utility model has been described above, but the utility model is not limited to the foregoing description.Can do all changes in the utility model technological thought scope, they all belong to protection domain of the present utility model.
