Embodiment Hereinafter, an embodiment of the present invention will be described with reference to FIG. 1 and FIG. FIG. 1 shows a first embodiment of the present invention.

As shown in the figure, the waste treatment apparatus is provided with a waste input port 1, and the waste input port 1 has a waste input port 2
Are provided to be freely opened and closed. A waste treatment chamber 3 is provided below the waste inlet 1, and a waste storage container 4 is suspended inside the waste treatment chamber 3. A plurality of air holes 5 are formed in the side surface of the waste storage container 4, and a net-shaped flowable waste storage container 6 having air permeability is detachably suspended inside the waste storage container 4. . The air holes 5 may be formed in the bottom of the waste container 4.
The fluidized waste storage container 6 is made of metal or synthetic resin or paper satisfying heat resistance.

An air supply pipe connected to the blower 10 at the bottom of the waste treatment chamber 3
12 is provided, and a heater 7 serving as a heating device for heating the air blown from the blower 10 is provided on the outer surface of the air supply pipe 12. Further, a temperature detector 8 for detecting the temperature of the blown hot air is disposed in the waste treatment chamber 3. 11 is a blower
There are 10 air supply rooms.

A catalyst chamber 14 containing a catalyst 13 is provided downstream of the upper part of the waste treatment chamber 3, and an exhaust port 15 is provided downstream of the catalyst chamber 14. The waste treatment chamber 3 and the exhaust port 15 are connected by an exhaust pipe 16, and the exhaust port 15 is opened outside the outer wall 17.

If the characteristics of the exhaust gas 18 are good, the catalyst 13 and the catalyst chamber 14 need not be provided. Further, the waste inlet 2 has excellent heat resistance, and is formed to have high airtightness so as not to have an odor.

In the above configuration, the waste 19 input from the waste input port 1 is stored in the fluidized waste storage container 6. When the blower 10 and the heating device 7 are started in this state, the air 9 in the air supply pipe 12 is heated and becomes hot air, and is sent into the waste treatment chamber 3. The hot air flows into the waste storage container 4 through a plurality of air holes 5 provided on the side surface of the waste storage container 4,
It flows from the lower part to the upper part of the breathable fluid waste container 6 and directly heats the waste 19 in the fluid waste container 6. In the waste treatment chamber 3, the temperature detector 8 detects the temperature of the hot air, and controls the heating device 7 to a predetermined temperature.

When the drying of the waste 19 proceeds, an exhaust gas 18 containing moisture, decomposition gas, and the like is generated.The exhaust gas 18 passes through the exhaust pipe 16 and is purified by the catalyst 13 provided in the catalyst chamber 14,
The odor is removed and exhausted from the exhaust port 15. Exhaust gas 18
If the characteristics of the catalyst are good, the catalyst 13 and the catalyst chamber 14 may not be provided. However, the provision of the catalyst 13 is particularly effective in removing the odor since the hydrocarbon-based gas can be reliably purified. is there.

As described above, according to the waste treatment apparatus of the embodiment of the present invention, since the waste 19 is directly heated by the hot air, the heating efficiency is high, and the water contained in the waste 19 can be uniformly removed. As a result, the treated waste 19 does not rot and becomes sanitary.

Further, some of the plastic waste that may be mixed into the waste 19 contains chlorine, and when heated to a predetermined temperature or more, the generated gas after the treatment may become a problem. On the other hand, in this embodiment, the temperature in the waste treatment chamber 3 is suppressed to a temperature lower than the temperature at which harmful gas is generated (about 200 ° C.). With this temperature setting, the weight and volume of the waste 19 are reduced, and clean and efficient waste treatment can be performed.

Next, a second embodiment is shown in FIG. The same parts as those shown in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in the figure, a magnetron 20 which is a heating device for microwave-treating the waste 19 via a microwave transmitting wall 22 and a waveguide 21 is disposed on the outer surface of the waste treatment chamber 3. ing. The power of the heater 7 and the magnetron 20 can be increased or decreased by a control device (not shown).

In the above configuration, the waste 19 input from the waste input port 1 is stored in the fluidized waste storage container 6. In this state, when the blower 10, the heater 7 as the heating device, and the magnetron 20 are started, the waste 19 is directly heated by the hot air and the microwave is heated as in the first embodiment. The garbage in the waste 19 contains a large amount of water, and microwaves are selectively absorbed by the water in terms of characteristics, so that the garbage can be effectively dried.

However, microwave oscillation consumes a large amount of power, and the temperature for moisture can easily be raised to around 100 ° C, but for plastics garbage, the temperature rises to around 200 ° C, the processing temperature. There is a characteristic that it is difficult to make it. According to this property, the heater 7 during waste disposal
By changing at least one of the power of the magnetron 20 and the power of the magnetron 20, the power consumption can be reduced, and the food waste and the plastic waste can be effectively heated.

For example, in general, if a part of the waste 19 is frozen,
Due to the low microwave absorption properties of the ice, the ice cannot be heated efficiently. In addition, if the power of the magnetron 20 is excessively increased while the water content of the waste 19 is high, boiling may occur. Therefore, while the water content of the waste 19 is equal to or higher than the predetermined value, the magnetron 20 is heated to the predetermined power or lower, and the heater 7 is set to the predetermined power for heating. If the power of the magnetron 20 is changed to a predetermined power and the power of the heater 7 is changed to a predetermined power or less when the power becomes less than the predetermined value,
The heating efficiency can be improved, and the waste 19 can be dried without boiling.

In addition, the use of a net-shaped bag as the fluid-type waste storage container 6 has the advantage that not only the air permeability at the time of heating can be improved, but also the bag can be easily disposed of in a bag after the waste treatment. In addition, it does not touch the waste 19 after the treatment, which is preferable in terms of sanitation.

Effect of the Invention As is clear from the description of the above embodiments, according to the present invention, the waste is directly heated by hot air, so that the heating efficiency is high and the water contained in the waste can be uniformly removed. it can. Therefore, the treated waste becomes sanitary without decay. In addition, even if plastic waste is mixed, the weight and volume of the waste are reduced at a temperature at which no harmful gas is generated in the waste treatment chamber, so that clean and efficient waste treatment is performed. be able to. Furthermore, a heater and a magnetron are used together as a heating device, and at least one of the power of the heater and the power of the magnetron is changed during waste disposal, thereby reducing power consumption and reducing food waste and plastic waste without boiling. Can be heat-treated efficiently. In addition, the odor generated during waste treatment can be removed by the catalyst provided downstream of the waste treatment chamber. Clean treatment and waste that is easy to control during treatment and has high heating efficiency A processing device can be provided.
