Description
Technical Field
The invention relates to the technical field of garbage treatment equipment, in particular to a chain plate type grate furnace.
Background
With the continuous development of economy and the acceleration of urbanization, both domestic garbage and industrial production garbage are multiplied. At present, the mode of garbage disposal is mainly incineration, the volume of general garbage can be reduced by 80 percent through combustion, the volume of the garbage is greatly reduced, the heat generated by combustion can be utilized for power generation and heat supply, the purpose of energy recovery is achieved, and the ash and slag after incineration can be used for making bricks. However, the waste is complicated in composition, and various combustibles therein have different densities, shapes, chemical properties, ignition and combustion characteristics, so that they exhibit different combustion speeds and burn-out times in the incinerator, and thus it is difficult to control the combustion process and ensure sufficient combustion, and in addition, the disposal of waste residues is a big problem. The existing waste incineration system is huge in structure, unconcentrated in heat, high in energy consumption, often insufficient in combustion, high in smoke impurity generated, difficult to process, troublesome in ash treatment and urgently needed to be optimized.

The invention aims to provide a chain plate type grate furnace, which improves the combustion state and the quality of discharged flue gas and improves the ash treatment efficiency.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a chain slat type grate furnace, it includes the furnace body, the furnace body divide into main combustion chamber, two combustion chambers and middle chamber, main combustion chamber adopts tunnel type structure, its bottom slope just is provided with chain slat type grate, it is provided with blevile of push to go up tunnel mouth department, middle chamber is connected to lower tunnel mouth, the bottom of middle chamber is provided with the slagging-off machine, two combustion chambers are located main combustion chamber's below and the middle chamber of adjacent, set up the mouth of advancing cigarette with two combustion chambers intercommunication on the middle chamber, be provided with a plurality of baffling boards in the two combustion chambers, the bottom of two combustion chambers is for leaking hopper-shaped and also connecting the slagging-off machine.
Furthermore, a stirring device is arranged at the opening of the lower tunnel and comprises a swinging plate hinged on the furnace body, and the materials falling freely on the self-chain plate type grate contact with the swinging plate.
Further, the inclination angle of the bottom of the main combustion chamber is 40 degrees.
Further, the pushing device comprises a pushing rod which moves transversely, and the pushing rod is driven by the air cylinder.
Furthermore, a plug-in plate type valve is arranged at the opening of the upper tunnel.
Furthermore, a plurality of observation ports are arranged on the furnace body.
In conclusion, compared with the prior art, the chain plate type grate furnace has the advantages of compact structure, high energy utilization rate, full drying, pyrolysis and combustion, convenience in ash collection and high flue gas cleanliness.
Drawings
Fig. 1 is a schematic structural diagram of a chain-grate stoker furnace according to an embodiment of the present invention.
Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
Referring to fig. 1, the present embodiment provides a chain-plate type grate furnace, which is mainly used for treating domestic garbage, and includes a furnace body 1, wherein the furnace body 1 is divided into a main combustion chamber 2, a secondary combustion chamber 3 and an intermediate chamber 4.
The main combustion chamber 2 adopts a tunnel type structure, the bottom of the main combustion chamber is inclined and provided with a chain plate type fire grate 5, the preferred inclination angle is 40 degrees, a pushing device 6 is arranged at the position of an upper tunnel opening, the pushing device 6 mainly comprises a pushing rod which moves transversely, the pushing rod is driven by an air cylinder, and a lower tunnel opening is connected with the middle chamber 4. In particular, a plug-in plate type valve 7 is arranged at the opening of the upper tunnel and is used for sealing the furnace body 1 when the blanking is not carried out.
The domestic garbage is pushed to the chain plate type fire grate 5 from the material pushing device 6, after being dried and pyrolyzed in the tunnel along with the chain plate type fire grate 5, the carbonized garbage generates gasification combustion reaction under the action of gasification agent air, the generated heat is supplied to the heat required by the drying and pyrolyzing of the domestic garbage, and finally ash falls to the middle chamber 4 from the lower tunnel opening.
The lower tunnel mouth is provided with a stirring device 8, the stirring device 8 comprises a swing plate hinged on the furnace body 1, and the materials falling freely from the chain plate type grate 5 contact with the swing plate. The bottom of the middle chamber 4 is provided with a slag remover 9, the bottom of the embodiment is provided with two slag removing positions, and ash can be scattered through the oscillating plate, so that slag is conveniently removed.
The second combustion chamber 3 is positioned below the main combustion chamber 2 and is adjacent to the middle chamber 4, a smoke inlet 10 communicated with the second combustion chamber 3 is arranged on the middle chamber 4, a plurality of baffle plates 11 are arranged in the second combustion chamber 3, and the bottom of the second combustion chamber 3 is funnel-shaped and is also connected with a slag remover 9. The gas generated by pyrolysis enters the secondary combustion chamber 3 for high-temperature combustion again, so that dioxin and the like are avoided, and the heat generated by secondary combustion can also return to the main combustion chamber 2 and the intermediate chamber 4 for use.
In addition, the furnace body 1 is also provided with a plurality of observation ports 12 which are respectively arranged in the main combustion chamber 2, the bottom of the secondary combustion chamber 3, the middle chamber 4 and the like, so that the combustion state and the ash slag processing condition can be conveniently observed.
In conclusion, the chain plate type grate furnace has the advantages of compact structure, high energy utilization rate, full drying, pyrolysis and combustion, convenient ash collection and high flue gas cleanliness.
The foregoing embodiments are merely illustrative of the principles and features of this invention, which is not limited to the above-described embodiments, but is capable of various modifications and changes without departing from the spirit and scope of the invention, which are intended to be within the scope of the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
