Abstract
The utility model relates to a device of a furnace in a fluid bed efficiently utilizing coal cinder and coal gangue. The device comprises a furnace in the fluid bed. The device is characterized in that a feed inlet for inputting coal cinder and coal gangue is arranged at the top of the furnace in the fluid bed. An air inlet connected with an air blower is arranged at the bottom of the furnace in the fluid bed. The furnace in the fluid bed is internally provided with an air distributing plate which is provided with a plurality of air caps. The air caps are mushroom-shaped. The device provided by the utility model uses coal cinder and coal gangue without sulphur as fuel, so that the cost is saved and the device is green and environment-friendly. The mushroom-shaped air caps are smaller in aperture and better in air distributing uniformity, so that the coal cinder and coal gangue can be adequately combusted.
Description
Technical field
The utility model relates to a kind of boiling furnace device that efficiently utilizes cinder, gangue.
Background technology
At present, in the production process of precipitated silica, need to carry out drying to the precipitated silica filter cake after filtering, manufacturer generally adopts spray dryer again, and the energy adopts coal-fired indirect heat exchange hot-blast stove, and hot-blast stove is fluidized bed furnace.Existing fluidized bed furnace can only be take fire coal as raw material, can not act as a fuel with cinder and gangue compound, not only production cost is high, and because fire coal contains a large amount of element sulphurs, therefore produce a large amount of toxic gases during burning, serious harm is to producers and surrounding enviroment.
Summary of the invention
In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of boiling furnace device that efficiently utilizes cinder, gangue of saving cost and environmental protection.
To achieve these goals, the technical solution of the utility model is: a kind of boiling furnace device that efficiently utilizes cinder, gangue, comprise fluidized bed furnace, it is characterized in that: the top of described fluidized bed furnace is provided with for the charging aperture that drops into cinder and gangue, the bottom of described fluidized bed furnace is provided with the air inlet that is connected with air blast, be provided with air distribution plate in the described fluidized bed furnace, be provided with a plurality of blast caps on the described air distribution plate.
Further, described blast cap is mushroom-shaped.
Compared with prior art, the utlity model has following advantage: this efficiently utilizes boiling furnace device simple in structure of cinder, gangue, can take the cinder of sulfur-bearing not and gangue as fuel, not only save cost, and can not produce the toxic gases such as sulfur dioxide, environmental protection; Its mushroom-shaped blast cap aperture is less, cloth wind uniformity is better, and be conducive to fully burn not cinder and the gangue of sulfur-bearing efficiently utilize cinder and gangue.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment.
Among the figure: 1-fluidized bed furnace, 1-1-charging aperture, 1-2-air inlet, 1-3-air distribution plate, 2-air blast.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further elaborated.
With reference to figure 1, a kind of boiling furnace device that efficiently utilizes cinder, gangue, comprise fluidized bed furnace 1, it is characterized in that: the top of described fluidized bed furnace 1 is provided with for the charging aperture 1-1 that drops into cinder and gangue, the bottom of described fluidized bed furnace 1 is provided with the air inlet 1-2 that is connected with air blast 2, be provided with air distribution plate 1-3 in the described fluidized bed furnace 1, evenly be provided with a plurality of blast cap 1-4 on the described air distribution plate 1-3.
In the present embodiment, described blast cap 1-4 is mushroom-shaped, has the advantages such as the aperture is less, cloth wind uniformity is better; Certainly blast cap also can be other shapes such as bell shape, umbrella shape.
The course of work of the present embodiment is as follows: cinder and gangue are dropped in the fluidized bed furnace 1 from charging aperture 1-1, air blast 2 passes into air in the fluidized bed furnace from air inlet 1-2, the air again blast cap 1-4 from the air distribution plate 1-3 enters in the combustion chamber of fluidized bed furnace 1, so that cinder and gangue fully burn.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
