Description

Description: TECHNICAL FIELD The present invention relates to an inductive heating waste incinerator that burns and decomposes household garbage, such as garbage, and substances that are harmful to the human body when discarded as they are. Is.

[Conventional technology]

Household waste has the inconvenience that each household must store the waste somewhere before it is transported by a cleaning vehicle in the waste transport processing of the city or town in which it resides. Waste such as food decays rapidly. Also, various other disposable items were bulky and required various types of storage space and boxes. Each household is struggling to solve this problem. For example, a crusher may be installed in the kitchen to dispose of waste. These are extremely inconvenient because a waste supply pipe must be installed.

FIG. 5 is a block diagram showing a conventional waste treatment apparatus disclosed in, for example, Japanese Patent Laid-Open No. 61-205719. In the figure,
Waste material put into the furnace (1) is squeezed by the piston (2) to subdivide glass or pottery in the waste material, a cardboard case,
The waste such as wood is squeezed and the waste liquid in the waste is discharged. The waste is incinerated by the heater (3), and the discharged waste liquid is stored in the waste liquid tank (4) and then discharged to the external drainage network by the pump (5).

[Problems to be solved by the invention]

In such a waste treatment device, various components contained in the waste are hardly decomposed and eventually flow out to the sea or river. Therefore, in order to protect the earth from pollution, more complete decomposition of waste is required. Further, in the electric resistance heating method, the heat transfer to the heating element is due to heat dissipation and heat transfer, so if the heat of the heating element is removed,
There was a limit to the heat transfer rate that was supplied, and it was difficult to fundamentally decompose waste.

The present invention has been made to solve the above problems, and an object thereof is to obtain an induction heating type waste incinerator that burns and decomposes as it is by supplying a large amount of energy to the waste.

[Means for solving the problem]

The device according to the present invention is a device for inductively heating a combustion chamber that comes into contact with an incineration object that is waste to raise the temperature to a predetermined temperature, and at that time, thermally decomposes the incineration object by the heat while supplying air. Is.

[Action]

The combustion chamber in the present invention is composed of a metal such as SUS in which an electric current flows, and a current is passed through an induction heating coil wound around the combustion chamber to cause a magnetic flux to penetrate into the combustion chamber. The flowing eddy current itself generates Jewel heat and raises the temperature.

Then, air is supplied into the combustion chamber to oxidize and decompose the incineration object.

Next, the operation will be described. The lid (6a) is opened to store the incineration object inside the combustion chamber (6), and the lid (6a) is closed and sealed. Next, a high-frequency current is passed through the induction heating coil (8) by the power supply equipment (9) to induction-heat the combustion chamber (6). By this operation, when the inner surface of the sealed metal combustion chamber (6) is heated to the ignition temperature or the ignition temperature of the incineration object, the incineration object comes into contact with the inner surface of the combustion chamber (6) which is the heating section. Since it starts burning from the part where
Energy from the induction heating coil (8) can be efficiently supplied to the burned material. Furthermore, at that time, the air supply nozzle (11) directly supplies air to the contact portion between the inner surface of the combustion chamber (6) and the burned material to supply sufficient oxygen to the burned material, thereby burning the burned material. And the incomplete combustion due to oxygen deficiency, which is caused by the temperature difference between the contact area between the inner surface of the combustion chamber and the inner surface of the combustion chamber (6), can be prevented in advance, and the incinerated material is almost completely oxidized while maintaining the high combustion temperature. Decomposes into water vapor and waste gas. The water vapor and the waste gas are released to the atmosphere through the exhaust pipe (13).

In FIG. 2, (14) is a cooling chamber for cooling steam and waste gas in the discharge pipe (13), (15) is a cooling water supply port of the cooling chamber (14), and (16) is for the cooling chamber (14). Cooling water drain, (1
7) shows a waste liquid of water vapor and waste gas cooled by the cooling chamber (14), and (18) shows a waste liquid tank for storing the waste liquid (17).

Next, the operation will be described. Water vapor and waste gas generated from the inside of the combustion chamber (6) are guided to the discharge pipe (13) and enter the cooling chamber (14). The cooling chamber (14) is cooled by cooling water, and the steam and waste gas are condensed to form a waste liquid (1
7) The waste liquid (17) is stored in the waste liquid tank (18).

FIG. 3 shows another embodiment of the cooling chamber (14), (19)
Indicates a liquid having a large latent heat of vaporization. A fluid (19) having a large latent heat of vaporization is enclosed in a cooling chamber (14) in a movable state to enhance the cooling effect of steam and waste gas, and the cooling chamber (14) is made compact.

Reference numeral (20) denotes a regulating valve for adjusting the supply amount of the waste liquid (17) to the combustion chamber (6), and (21) denotes a supply pipe for supplying the waste liquid to the combustion chamber (6).

Next, the operation will be described. Steam and waste gas generated from the combustion chamber (6) pass through the discharge pipe (13) and the cooling chamber (14)
It is cooled and condensed in the waste liquid tank (18). Next, the waste liquid (17) in the waste liquid tank (18) is adjusted by the adjusting valve (20) and is again supplied from the waste liquid supply pipe (21) to the inside of the combustion chamber (6) for re-incineration and re-decomposition. Be done. This operation enables completely sealed incineration. Further, the combustion chamber (6) is disposed in the heat insulating material (7), and the lid (6a)

[Effects of the Invention] As described above, according to the present invention, the induction heating coil is used to heat the sealed metal combustion chamber, and the incineration object is brought into contact with the combustion chamber to be housed therein. Energy from the coil can be efficiently supplied to the burned material. Furthermore, by directly supplying air to the contact portion between the inner surface of the combustion chamber and the incineration object and supplying sufficient oxygen to the heating portion, a temperature difference between the contact portion between the incineration object and the inner surface of the combustion chamber occurs. By preventing incomplete combustion due to lowering of combustion temperature and oxygen deficiency, and by almost completely oxidizing and decomposing while maintaining a high combustion temperature, it is possible to incinerate and decompose as it is. Also, by simultaneously generating steam and waste gas as waste liquid in the cooling chamber and incinerating it again in the combustion chamber, it becomes possible to incinerate completely and incinerate and disintegrate the incineration object in a more complete direction. And so on.
