Abstract

PURPOSE:To facilitate the loading of a treating vessel with trash and to leave no portion of a load unburned by forming a flange at the top end of the vessel, by forming many openings in the side of the vessel, and by forming inside a combustion furnace a flange holder on which the flange is put in such a manner as to support the vessel with its bottom in suspension. CONSTITUTION:A combustion furnace 1 is formed of a casing 12 having a lid 4 freely opening to allow trash 6 to be thrown in and a lining 11 covering the inner wall surfaces. Inside the combustion furnace 1 is mounted a treating vessel 5. The top end of this treating 5 is turned outward, forming a flange 14, and in the side of the treating vessel 5 are formed a plurality of openings 16 all around circumferentially. A step serving as a flange holder 15 is formed in the inner wall of the lining 11 at an upper position, an exhaust gas outlet 9 in the side wall above this flange holder 15, and an air inlet 7 in the bottom. A furnace heater 3 is circumferentially set on the inner wall surfaces under the flange holder 15. This constitution prevents the incineration from leaving an urburned portion of a load lopsidedly and enables treating the load efficiently within a shortened period of time.

06 is heated to reduce its weight in a kiln.

The air necessary for combustion is supplied from the air supply port 107 to the air supply blower 108
Flows into the processing container 105 due to this. The exhaust gas generated by combustion enters the purifier 110 through the exhaust port 109, is purified by the purification probe 102 which has already been heated to the reaction temperature by the exhaust gas heater 113, and is discharged to the outside. .

Problems to be Solved by the Invention In such a conventional configuration, since the processing container 106 has a protrusion 116 that protrudes inside, it is difficult to put bulky waste into the processing container 106.
In addition, as the incineration process progresses, the garbage 1 around the furnace heater 103
Even if the amount of waste 06 is reduced, there is a problem that the upper part of the garbage 106 is stuck between the upper part of the protrusion 116 and the side wall surface of the processing container 105, and it gets caught and does not fall off, so it takes time to dispose of the unburnt residue. The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a waste processing device that allows waste to be easily put into a processing container, leaves no burnt residue, and has a short processing time.

Means for Solving the Problems In order to solve the above problems, the garbage disposal device of the present invention has an interior lined with a heat insulating material, an electric wire is pasted on the inside, a lid that can be opened and closed at the top, and a lid on the bottom. A processing container made of a heat-resistant material and into which waste is input is provided inside a combustion furnace having an air supply port and an exhaust port on a side wall, the processing container having a flange at an upper end and a large number of openings on an outer peripheral side surface, The structure has a structure in which the bottom part is suspended and latched to the flange receiver of the flange provided inside the combustion furnace.
With this structure, the garbage put into the processing container is stacked one on top of the other in order from the bottom, and the whole is heated by the radiant energy of the electric heater and air supplied from the opening on the outer peripheral side, and ignites and burns.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2.

As shown in FIG. 1, the combustion furnace 1 consists of a frame 12 with a lid 4 that can be opened and closed into which waste 6 is thrown, and a furnace material 11 that is attached to the inner wall of the frame 12. A container 5 is attached. The upper end of the processing container 6 is a flange 14 folded back to the outside, and a plurality of openings 16 are provided around the entire circumference of the side surface. The furnace material 11 has a step on the upper inner wall surface to form a flange receiver 15, an exhaust port 9 is attached to the side wall above the flange receiver 16, a furnace heater 3 is attached to the lower inner wall surface, and an air supply is provided on the bottom surface. A mouth 7 is provided. The processing vessel 6 receives the flange 14 on the flange receiver 16, and the bottom part is equipped with the furnace material 11jl, lαtrv Renault, the furnace 6 and the furnace heater 3.
A gap is provided between them through which supply air flows. A supply air blower 8 is connected to the air supply port 7 , and a υ converter 11 consisting of an exhaust gas heating heater 113 and a purification probe 102 is connected downstream of the exhaust port 9 .
0 is connected.

In the above configuration, the lid 4 is opened and the garbage 6 is dumped into the processing container 6.
When the furnace heater 3 is turned on and the lid 4 is closed, the furnace heater 3 emits infrared rays with strong radiation intensity. This infrared rays pass through the opening 16 of the processing container 6, as shown by arrow 3A, and are directly transmitted to the waste 6. Further, the thermal energy received by the processing container 6 is transmitted to the waste 6 as secondary radiant heat.

Due to these two types of thermal energy and the air 8A flowing into the processing container 5 from the opening 16, the garbage 6 starts drying, igniting, and burning from the outer periphery, and its weight is reduced from the outer periphery.

Then, the upper garbage 6 falls down to the place where the weight has been reduced, and this process is repeated. When the weight of the garbage 6 progresses and the entire garbage 6 reaches the ignition point, the flame spreads throughout the garbage, resulting in final combustion and turning into ash. At this time, from the opening 16 to the processing chamber 21 5 F/I
f. By the air blower 48, the waste 6 passes through the space between the processing container 6 and the furnace heater 3 and flows to the opening 16. Exhaust gas 9A consisting of bad odor, steam, and smoke generated by combustion enters the purifier 110 through the exhaust port 9, and has already been heated to a reaction temperature (eoo°C to 9oo'C) by the exhaust heating heater 113.
t: ) is purified by the purification catalyst 102 and discharged to the outside.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, radiant heat and air are directly applied to the waste from a large number of openings provided on the outer periphery of the processing container, so that it can be applied to a wide area of the entire outside. It performs heating and air supply, has a large area for simultaneous combustion, and eliminates the possibility of getting caught due to unevenness of unburned parts during incineration, making it possible to process efficiently and in a short time.
