たままであるので、煙が外部に排出されることもない。In this state, when the power switch 50 is pressed to bring it into conduction, first the electric heater 45 is energized. At this time, since the electric heater 45 is arranged at a position spaced inwardly along the tapered surface 28a, the dust 9 should be brought into contact with the electric heater 45 over a relatively wide range near the tapered surface 28a. Electric heater 4
A relatively wide range of dust 9 can be heated as the surface temperature of 5 rises. Moreover, since the dust input port 30 is closed by the lid member 31, the air supply to the first combustion chamber 33 from above is blocked, and the air supply is insufficient, so that the dust 9 in the first combustion chamber 33 is removed. It does not burn up all at once, and since the first and second blowers 48 and 49 also remain stopped, smoke is not emitted to the outside.

The supply of air to 3 will more reliably ignite. Moreover, the supply of air to the first combustion chamber 33 is performed by the plurality of first air supply nozzles 37, 3 disposed on the tapered surface 28a.
.., And the combustion air can be effectively supplied to the vicinity of the electric heater 45, so that the ignition of the refuse 9 becomes more reliable, and the refuse 9 is more stable in the vicinity of the tapered surface 28 a. Combustion can be started.

The refuse 9 which is in a state of being compressed in 3 continues gradual combustion near the tapered surface 28a by a relatively small amount of combustion air supplied from the first air supply nozzles 37. The generated incomplete combustion gas, when flowing from the first combustion chamber 33 to the second combustion chamber 34, is supplied in a sufficient amount from the second air supply nozzles 38 to the upper part of the second combustion chamber 34. The combustion air is allowed to burn with a higher complete burnup.

できる。In order to continue the gentle combustion in the first combustion chamber 33 in a stable manner, it is necessary to reliably supply the air to the combustion section near the tapered surface 28a at an appropriate supply rate. Thus, no combustion air is supplied from above the first combustion chamber 33, and the plurality of first air supply nozzles 37, 37,.
.. Are arranged in such a direction that the combustion air supplied from 7, 37... Into the first combustion chamber 33 is swirled along the tapered surface 28a, so that it is necessary to continue gradual combustion. The combustion air at a constant speed.
The fuel can be supplied to the combustion section near “a”. Moreover, since the air generates a swirling flow in the first combustion chamber 33,
It is possible to make the gas retention time in the first combustion chamber 33 relatively long and suppress the occurrence of combustion unevenness in the first combustion chamber 33 as much as possible.

ができる。The second combustion chamber 34 has a circulation area larger than the opening area of the outlet 35 at the lower end of the first combustion chamber 33 and is continuous with the first combustion chamber 33. When the gas flows to the second combustion chamber 34, the gas flow is restricted at the outlet 35 of the first combustion chamber 33,
Even if combustion unevenness occurs in the first combustion chamber 33, the incomplete combustion gas or smoke and the high-temperature gas generated by complete combustion are effectively mixed at the outlet 35, and the second air supply nozzle 38 , 38 .. from the outlet 35
Since the mixed gas is supplied to the upper part of the second combustion chamber 34 toward the mixed gas, combustion with higher complete burnup can be achieved.

The single sirocco fan 39 makes it possible to contribute to the reduction of the number of parts. Further, by setting the inner diameters of the plurality of first air supply nozzles 37, 37 ... And the inner diameters of the plurality of second air supply nozzles 38, 38 ..., the amount of air supplied from a single sirocco fan 39 is changed to the first combustion. A relatively small amount of air to the chamber 33 side,
It can be easily distributed to a relatively large amount of air to the combustion chamber 34 side, and complicated air supply amount control is unnecessary.

る。By the way, when the ash generated by the combustion in the first combustion chamber 33, the incompletely burned material which becomes brittle due to the progress of the combustion to some extent, falls in the first combustion chamber 33 due to gravity. If the outlet 35 is blocked even momentarily, the flow of the supply air or the combustion gas in the first combustion chamber 33 is disturbed and the combustion becomes unstable even if temporarily. However,
At the lower portion of the tapered surface 28a, a three-dimensional lattice-shaped rostrator 43 extending upward so as to cover the outlet 35 is attached, and the sum of the opening areas of the plurality of openings 44, 44. The opening area of each of the openings 44 is smaller than the opening area of the outlet 35. Therefore, of the ash and incompletely burned materials that have fallen, those larger than the opening area of the outlet 35 can be temporarily retained around the rostrum 43 in a range wider than the opening area of the outlet 35. Since the total opening area of the openings 44 is sufficiently large, the gas flow is not obstructed by the roastles 43. Further, by being blown off by the gas flow, each of the openings 44, 44.
Ash and incompletely burned materials that have become smaller than
3 to the outlet 35, but since the individual opening area of each of the openings 44 is smaller than the opening area of the outlet 35, the outlet 35 is not blocked by the falling object, and the first combustion chamber It is possible to prevent the flow of the supply air and the combustion gas in the inside 33 from being disturbed, and to maintain more stable combustion.

可能となる。In such a refuse incinerator 5, since the dust 9 is continuously burned little by little in the vicinity of the tapered surface 28a, the amount of heat generated per unit time does not increase, and therefore the incinerator main body 22 has a high temperature. It is possible to avoid such a situation, and to eliminate the restriction on the installation place that accompanies the high temperature of the incinerator 5 when it is used at home. In addition, the gradual continuation of the combustion of the refuse 9 suppresses the amount of combustion gas generated per unit time, and suppresses the generation of unburned gas as much as possible by sufficiently supplying combustion air. Exhaust gas can be purified as much as possible. Therefore, the refuse incinerator 5 can be installed in each household with almost no problem, and the garbage 9 is incinerated by being disposed of frequently every time the garbage 9 comes out, with the feeling that the refuse is disposed of in the trash box. , It is possible to reduce the weight.

The amount of heat from the combustion gas is transmitted to 7 and the garbage disposal tank 8. This makes it possible to reduce the volume by heating the PET bottle 16 and the Styrofoam product 17 and the like that are pressurized by the weights 16 and 17 in both the volume reduction treatment tanks 6 and 7. The garbage processing tank 8 can be maintained at an optimum temperature suitable for organic processing such as fermentation volume reduction.
Thus, the heat transfer and the first and second blowing fans 48,
The temperature of the gas exhausted from the exhaust port 21 can be reduced by the air mixing from the exhaust port 49.
