DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for incineration of excrement in a simple toilet used at a construction site, a disaster area, etc., or for incineration of garbage at home. The present invention relates to a waste incinerator.

[0002]

2. Description of the Related Art A portable toilet temporarily used at a construction site or the like is usually of a pumping type. For example, Japanese Patent Publication No. 6-57190 discloses a simple toilet in which a pump is arranged in a toilet tub so that excrement can be automatically discharged.

[0003] In such a pump-type simple toilet, since excrement is accumulated in the toilet tub, there is a possibility that a bad smell is generated and the surrounding environment is spoiled. In addition, although the excrement in the toilet tank can be discharged by the pump, the excrement must be transported or transported to an appropriate treatment facility for processing, and the work is troublesome. There is also.

[0004] Japanese Patent Publication No. 6-83829 discloses a microbial sewage treating agent used for a vehicle toilet.
However, in such a sewage treatment agent, since it takes a long time to treat the excrement, there is a problem that the surrounding environment is impaired by a bad smell generated during the treatment. Further, the treated material treated with the sewage treatment agent must be separately disposed of, and the work is not easy.

[0005] JP-A-7-305959 discloses an apparatus for drying garbage. Even with such a drying apparatus, there is a problem that it takes a long time to dry the garbage and the surrounding environment is impaired by the bad odor generated during the drying. Also, it is not easy to treat the dried garbage.

[0006] Instead of such a method of treating excrement and garbage, a method of incinerating excrement and garbage has also been proposed.

[0007]

The excrement, garbage, etc.
Usually, it is incinerated in large-scale incineration equipment. Therefore, it is necessary to transport excrement and garbage to the incineration facility. In addition, there is a problem that the surrounding environment is significantly polluted by incineration of a large amount of excrement and garbage.

Recently, in a temporary toilet for temporary use,
An apparatus for incinerating excrement with an electric heater has been developed. Further, as a household garbage disposal apparatus, an apparatus for incinerating garbage with a heater has been developed. However, a device that directly heats excrement and garbage by an electric heater has a problem that the configuration for electrically insulating and the like is complicated and that maintenance is not easy. Moreover, because maintenance is not easy,
There is also a problem that it cannot be used stably for a long period of time and its life is short. In addition, it takes a long time to incinerate excrement and the like by the electric heater, and during that time, if an odor or the like is generated, the surrounding environment may be polluted.

The present invention has been made to solve such a problem, and an object of the present invention is to treat waste such as excrement and garbage in a relatively short time and stably for a long period of time. It is an object of the present invention to provide a waste incinerator that can be used.

As shown in FIG. 2, the incinerator 30 has a cylindrical heating furnace 31 whose upper surface is opened by ceramic and whose bottom surface is closed. The end of the connecting pipe 25 penetrates the peripheral surface of the upper end of the heating furnace 31, so that excrement flows into the heating furnace 31 from the toilet body 21 through the connecting pipe 25. ing. Heating furnace 31
Is configured to have an inner diameter of 210 mm and a height of 200 mm, for example, so that the internal capacity is about 2 liters.

An induction coil 34 is wound around the outer peripheral surface of the heating furnace 31 except for the upper end. The induction coil 34 is supplied with a high-frequency alternating current. The heating furnace 31 around which the induction coil 34 is wound is covered with a heat insulating material 35 except for its upper end. A thermocouple 44 for measuring the temperature of the peripheral surface is attached to the peripheral surface of the heating furnace 31.

In the heating furnace 31, there is arranged a cylindrical support 32 having an upper surface opened and a bottom surface closed by a porous ceramic. On the inner peripheral surface of the support 32,
A pair of recesses 32a are formed horizontally around the entire circumference at appropriate intervals above and below, and a pair of heating elements 33 formed in an annular shape by stainless steel are fitted and supported in each recess 32a. I have.

A heating furnace 31 extending upward from the heat insulating material 35
An exhaust pipe 36 is fitted in the upper end of the airtight container. The connecting pipe 25 penetrates the peripheral surface of the exhaust pipe 36 in an airtight state and penetrates the peripheral surface of the heating furnace 31. Exhaust pipe 36
Has a bellows-like lower peripheral surface, and expands and contracts vertically. Therefore, the heating furnace 31 can be removed from the exhaust pipe 36 by contracting the exhaust pipe 36 upward.

As shown in FIG. 1, an intake port 36a is provided in the middle of the exhaust pipe 36 so as to extend horizontally horizontally. The intake port 36a is exposed to the outside through the back surface 18 of the housing 10, and an intake fan 37 is mounted inside. Exhaust pipe 36
Inside, a heater 38 and a platinum catalyst 39 are arranged in order from the lower side above the intake port 36a.

A high-frequency oscillator 41 for applying a high-frequency alternating current to the induction coil 34 is provided below the floor surface 14 in the housing 10. The high-frequency oscillator 41 is disposed on a water tank 42 having a radiator function, and the high-frequency oscillator 41 is cooled by cooling water stored in the water tank 42.

Below the floor 14, a controller 43 for controlling the high-frequency oscillator 41 is arranged alongside the high-frequency oscillator 41. An output of a thermocouple 44 for detecting the temperature of the heating furnace 31 is given to the controller 43, and an operation panel 4 provided in the housing 10 is provided.
An output of 5 is also provided. The operation panel 45 is provided with, for example, an operation switch for the incinerator 30, a preheating switch for the heating furnace 31, a switch for switching between stool and urine, and the like.

The simple toilet having such a structure is provided with a toilet 20
When excrement is put into the toilet body 21, the toilet body 2
The check valve 24 that closes the dropper 23 is opened by the weight of the excrement, and the excrement passes through the connecting pipe 25 and is injected into the heating furnace 31 of the incinerator 30. When the excrement is put into the heating furnace 31, the high-frequency oscillator 41
A high frequency alternating current is applied to the induction coil 34. When a high-frequency AC current is applied to the induction coil 34, an eddy current is generated in each of the heating elements 33 made of stainless steel by the electromagnetic induction action, and each of the heating elements 33 is heated by Joule heat.
As a result, the excrement introduced into the heating furnace 31 is heated and incinerated.

Typically, 4 kW of electrical energy is about 956 c
al / s of thermal energy, and the heat of vaporization of water is
It is known to be 540 cal / g. For this reason, for example, 500 ml of urine at 20 ° C. becomes 500 × 80 to become 100 ° C.
A time of / 956 = 41 (sec) is required, and a time of 500 × 540/956 = 282 (sec) is required for vaporization.
Therefore, to vaporize 500 ml of urine, in theory, 41 + 2
82 = 323 (sec) is required. As a result, assuming that the heat conversion efficiency of the current applied to the incinerator 30 is 50%, urine at 20 ° C.
500 ml is processed in 646 (sec), ie, about 11 minutes.

As described above, the controller 43 controls the oscillation time of the high-frequency AC current by the high-frequency oscillator 41 based on the type of excrement input from the operation panel 45.

The combustion gas generated when the excrement is incinerated in the heating furnace 31 of the incinerator 30 is discharged to the outside through an exhaust pipe 36. In this case, a part of the combustion gas flows into the connection pipe 25, but the discharge port 23 of the toilet body 21
Is closed by the check valve 24, there is no risk of flowing into the housing 10 through the toilet body 21.

When the combustion gas generated from the heating furnace 31 is discharged to the outside through an exhaust pipe 36, an intake fan 37
The air sucked into the exhaust pipe 36 by the
Burned by. Thus, the gas flowing through the exhaust pipe 36 is further burned, and the burned gas is deodorized by the platinum catalyst 39. Therefore, since the combustion gas of the excrement is further burned and deodorized and discharged to the outside, there is no possibility of polluting the surrounding environment.

The temperature of the heating furnace 31 is detected by a thermocouple 44. When the heating furnace 31 is heated to a temperature equal to or higher than the set temperature, the controller 43 stops the oscillation of the high-frequency alternating current by the high-frequency oscillator 41 and stops the heating elements 33 from generating heat. I have. Therefore, abnormal heating of the heating furnace 31 is prevented.

When the preheating switch provided on the operation panel 45 is operated, the high frequency oscillator 41 is operated, and the heating furnace 31 is preheated to a predetermined temperature. Therefore, the excrement thrown into the heating furnace 31 can be quickly incinerated.

In the above embodiment, the simple toilet in which the waste put into the heating furnace 31 is excrement has been described, but the waste put into the heating furnace 31 is garbage which is garbage. The present invention can be applied to an incinerator.

[0034]

As described above, the waste incinerator according to the present invention arranges a dielectric heating element in a heating furnace and applies a high-frequency current to an induction coil disposed around the heating furnace. Since the heating element is configured to generate heat by the electromagnetic induction action, waste such as excrement and garbage can be directly heated by the heating element, and the incineration efficiency is significantly improved. In addition, since the heating element that comes into contact with waste such as excrement can be heated by the induction coil in a non-contact state, the configuration is simple, maintenance is easy, and stable for a long time. Can be used.
