Abstract

PROBLEM TO BE SOLVED: To eliminate the need for unhygienic work for removing feces from used diapers or the like by a method wherein a diaper or the like taken off a human body is placed into a treating container to be burned by a microwave irradiated and an exhaust gas containing generated odor is brought into contact with a liquid for the removal of the odor to be released into the atmospheric air. SOLUTION: A diaper or the like containing filth is placed into a tray 10 within a treating container 1 and a door of the treating container is closed. Now, when the diaper is irradiated with a microwave generated from a microwave generator 2, the microwave acts on moisture therein so that the temperature rises by heat generated to evaporate the moisture. As a result, with the pressure rising, steam generated reaches the inside of a water jacket 6 through an exhaust path 5. At this point, the steam is trapped by water in the water jacket 6 and an odorous gas (such as hydrogen sulfide or ammonia) is trapped by the water to deodorize. The trapping of the gas by the water requires a proper temperature and so, it is desired to control the temperature of the water with a heater 9 as required.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for treating combustible waste, and more particularly to a method for treating water and dirt-containing substances such as used diapers generated in homes and the like into ash. To a method and apparatus suitable for:

[0002]

2. Description of the Related Art Conventionally, used diapers and the like are disposed of stool in a toilet bowl and the rest is wrapped in vinyl and disposed of as household waste, or in some cases, is treated in a small incinerator. This treatment was a foul-smelling and filthy task.

[0003] In other words, there has been no method for sanitarily treating used diapers at home.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to eliminate the need for unsanitary work for removing stool from used diapers and the like, and to remove odors during incineration and diapers wrapped in vinyl until collection of household garbage. It is an object of the present invention to provide a waste disposal method and a waste disposal apparatus that can solve problems such as cumbersome storage.

[0005]

In order to solve the above problems, in the present invention, a diaper or the like removed from the body is placed in a processing container to remove moisture, irradiated with microwaves, and then burnt except for moisture. Let it. The gas containing the odor (combustion gas or the like) generated during this time is brought into contact with a liquid such as water to remove the odor and then released into the atmosphere.

[0006] According to the above configuration, the water used in the diaper is removed by microwave irradiation, and the remainder is burned to ash. The odor in the gas generated during this time is collected in the liquid, so that the exhaust gas is deodorized. Therefore, unsanitary work for removing stool from used diapers and the like becomes unnecessary, and the problem of odor at the time of incineration and the trouble of storing diapers wrapped in vinyl for a long time can be solved.

Embodiments of the present invention will be described below with reference to the drawings.

[0008]

FIG. 1 shows a first embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a processing container provided with a door (not shown) on a front portion. 2 is a well-known microwave generator having a built-in magnetron, 3 is a waveguide for guiding the microwave generated by the microwave generator 2 to the processing vessel 1, and 4 is an air pump for sending air into the processing vessel 1. is there. 5 is an exhaust passage for guiding the gas in the processing vessel from the processing vessel 1 to a water jacket 6 described below,
Reference numeral 6 denotes a water jacket serving as a liquid storage portion also serving as an upper wall of the processing container 1, reference numeral 7 denotes an exhaust pipe provided at an upper portion of the water jacket 6, reference numeral 8 denotes a deodorizer attached to the exhaust pipe 7, and It is packed with a well-known adsorption deodorant such as activated carbon. Alternatively, an ozone generator using an ultraviolet light bulb or a low-temperature combustion device using platinum as a catalyst may be incorporated. Reference numeral 9 denotes an electric heater inserted in the water jacket 6, and reference numeral 10 denotes a heat-resistant glass or ceramic tray that is contained in the processing container 1 and into which used diapers and the like are placed.

In such a waste disposal apparatus, a diaper or the like containing filth is put into a tray 10 in the processing container 1 and a door (not shown) of the processing container 1 is closed. Here, when microwaves generated from the microwave generator 2 are applied to the diaper, the diapers act on water to generate heat and increase the temperature, so that the water evaporates. Therefore, the pressure increases, and the generated steam reaches the water jacket 6 through the exhaust passage 5.
At this time, the steam is collected by the water in the water jacket 6, and the odorous gas (hydrogen sulfide, ammonia, etc.) in the steam is also collected by the water and deodorized.

In the first embodiment, in order to carry out more reliable deodorization, odors that have not been collected reach the deodorizer 8 and are absorbed by activated carbon or deodorized by ozone. Be affected. Therefore, in any case, the odorless gas is discharged out of the processing container 1. When the pressure is insufficient, the air pump 4 is operated.

In the first embodiment, when a low-temperature combustion device of a platinum catalyst is incorporated in the deodorizer 8, even if flammable gas is generated in the processing vessel 1, the device is incorporated in the deodorizer 8. It can be burned by a low-temperature combustion device of a platinum catalyst. Therefore, it is safe and can also perform deodorization.

After the water in the diaper and the waste in the processing container 1 is removed by the microwave treatment, combustible materials such as the diaper and the waste are usually ignited by continuously irradiating the microwave. A simple electric heater may be installed in the processing vessel 1 to assist the ignition. When the combustible material in the processing container 1 ignites, the microwave may be weakened or the generation of the microwave may be terminated. At this time, when the air pump 4 is operated, oxygen is supplied, so that combustion is continued or promoted. For this reason, the generated combustion gas reaches the water jacket 6 as in the case of steam, but dust and water-soluble gas in the gas are collected by the water in the water jacket 6. Even if the remaining gas has an odor, it is treated in the deodorizer 8 as in the case of the steam. If this is continued, combustibles other than moisture become ash. Although the processing vessel 1 is heated by the burning of combustibles (filtration and the like) in the processing vessel 1, in this embodiment, the water jacket 6 serving as a liquid storage section is heated.
Constitutes the upper wall of the processing container 1, whereby the processing container 1 can be cooled. Therefore, safety and reliability of the waste disposal device are ensured.

Since there is an appropriate temperature for collecting gas by water, it is preferable to control the water temperature by the heater 9 as necessary.

Furthermore, a small propeller is installed in the water jacket 6 and driven by the small propeller.
If the water inside is stirred, the efficiency of odor collection is improved. In addition, if an appropriate partition wall is provided in the jacket 6 and the passage distance of the gas from the inside of the water jacket 6 to the outside of the water jacket 6 is increased, the collection efficiency is improved. Further, if a pair of electrodes facing each other is provided in the water jacket 6 and an AC voltage is applied to the electrodes so that a gas passes between the electrodes, water is vibrated by electricity, and the efficiency of collection is increased.

Furthermore, if oxygen is supplied to the water in the water jacket 6, the water in the water jacket 6 can perform a chemical deodorizing action. Also,
It is preferable to generate oxygen from the water in the water jacket 6 by electrolyzing the water in the water jacket 6.

FIG. 2 shows a second embodiment in which the present invention is incorporated in a flush toilet unit. In the figure, reference numerals 1, 2, 3, 4, 5, and 10 indicate the same components as those in the first embodiment, respectively. Reference numeral 11 denotes a low tank (water tank) for a flush toilet that also serves as a liquid storage section of the present invention, 12 denotes a flush toilet, and 13 denotes a drain pipe of the flush toilet 12. That is, in the first embodiment, the generated steam, the combustion gas, and the like are guided to the water in the water jacket 6 which also serves as the outer wall of the processing container 1. In the second embodiment, the low tank of the flush toilet is used. 11 is a liquid storage unit, the exhaust port 5a of the exhaust passage 5 is disposed in the water in the low tank 11, and the steam and the combustion gas generated in the processing vessel 1 are introduced into the water in the low tank 11. different. In the first embodiment, the water in the water jacket 6 needs to be drained from time to time. In the second embodiment, when the toilet 12 is used, the water in the low tank 11 is automatically drained via the toilet 12 and the drain pipe 13. Since it is replaced, the trouble of water exchange can be saved.
The waste disposal apparatus of the second embodiment can be easily applied to an existing flush toilet.

Although the illustrated embodiment has been described above, the present invention is not limited to the above embodiment.
Various modifications can be made to the components within the scope of the invention described in the claims. For example, in the above-described first embodiment, water is put in the water jacket 6, but an acidic or alkaline chemical having a deodorizing effect may be added.
