Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decomposing device for decomposing waste discharged from general households and companies, and particularly to a toxic gas when incinerating rubber products and plastic products which have not been incinerated up to now. The present invention relates to a decomposing device for decomposing wastes, industrial wastes, etc. that generate waste.

[0002]

2. Description of the Related Art Conventionally, wastes discharged from various places such as households and companies are combustible wastes that can be incinerated and non-combustible wastes that generate toxic gas when burned like rubber products and plastic products. And waste resources such as paper and glass and aluminum products that can be reused as resources, and industrial waste such as waste oil and concrete and metal structures discharged from factories and facilities. Disposal processing is performed for each waste.

Generally, combustible waste is incinerated by an incinerator, and incombustible waste is buried in the earth and sand of a landfill or the like. Further, the resource waste is separated into paper, glass and aluminum, crushed and dissolved, and used as a resource. Furthermore, industrial waste is subjected to special processing, and special processing is performed corresponding to each.

[0004]

However, the conventional incinerator has a drawback that the waste that can be incinerated is restricted depending on the type of waste. Further, there is a drawback that smoke, gas, etc. are generated due to incomplete combustion during the incineration process, which adversely affects the surrounding environment. In the conventional incinerator, the waste is burned in the air for incineration.
If explosive material is mixed in the waste,
Problems such as equipment damage and human danger also occur.

Further, since incombustible dust and industrial waste that cannot be incinerated are buried in landfill sites, it is necessary to secure a site, and the bad odor generated by the wastes adversely affects the surrounding environment. .

Therefore, the present invention has been made in view of these points, and wastes of various forms can be treated, and smoke and harmful substances due to combustion of the treated matter can be treated during these treatments. It is an object of the present invention to provide a waste decomposition processing apparatus that does not generate gas and does not emit a foul odor or noise.

The crucible is supported and provided in the furnace body so that there is a gap between it and the outer periphery of the crucible, and the opening of the crucible is located inside the opening of the furnace body. It has a lid.

Further, a suction pipe for evacuating the inside of the crucible and for discharging gas generated when incinerating an object to be processed is provided, and a suction device connected to the other end of the suction pipe is provided. A material with high thermal conductivity that generates far infrared rays from the furnace body by providing a heating device for the gas etc. that heats the crucible in the gap with the outer periphery of the crucible in the furnace body, and projecting the exhaust pipe leading to the gap from the furnace body. The far-infrared decomposition device formed by

The invention according to claim 2 has a crucible having a space for accommodating an object to be incinerated and made of a material having a high thermal conductivity for generating far infrared rays, and a crucible other than the supporting portion. The crucible is supported inside the furnace body so that there is a gap between them, the opening of the crucible is located inside the opening of the furnace main body, and an opening / closing lid that closes these openings is provided.

Further, the inside of the crucible is closed by closing the opening / closing lid to be in a vacuum state, and a suction pipe for discharging gas generated when incinerating an object to be processed is provided from the inside of the crucible, and the suction is connected to the other end of the suction pipe. A vacuum device and a gas selection and extraction device are provided, and a heating device for gas, etc. that heats the crucible in the gap between the inner circumference of the furnace body and the outer circumference of the crucible is provided, and the exhaust pipe leading to the gap is projected from the furnace body. The far-infrared decomposition device is provided with a circulation path for returning the gas not extracted by the gas selection and extraction device to the heating device, and the end of the exhaust pipe is connected to the other end of the exhaust pipe connected to the clean filter. .

Further, the invention of claim 3 is the above-mentioned claim 1.
Alternatively, in addition to the apparatus of 2, the frame body covering the outer periphery of the furnace body is provided, and the furnace body is rotatably supported by rolls provided at appropriate places of the frame body, and the furnace body is driven to rotate appropriately. A drive source is provided, and the opening / closing lid is doubled as an inner opening / closing lid and an outer opening / closing lid, and the inner opening / closing lid and the outer opening / closing lid are rotatably supported with respect to each other. The opening and closing of the furnace body can be closed by the outer opening and closing lid, and the outer opening and closing lid is supported by the frame body and the like, and the gap between the furnace body and the crucible and the inside of the outer opening and closing lid can be closed. The far-infrared decomposition device is made to communicate with each other, and the exhaust pipe is projected from the outer opening / closing lid.

[0012]

According to the first aspect of the present invention, the opening / closing lid is opened, the furnace body and the opening of the crucible are opened, the object to be treated is put in the crucible, and the opening / closing lid is closed again. This uses a metal fitting or the like to seal the inside of the crucible. After that, the air in the crucible is sucked by a suction tube to make the inside of the crucible into a vacuum state. Therefore, a heating device for gas or the like is operated to heat the crucible whose heating temperature and time are changed depending on the type of the object to be treated.
The combustion exhaust at that time is exhausted to the outside from the exhaust tube of the furnace body. Further, this heating causes the crucible to emit far-infrared electromagnetic waves.

As a result, the object to be treated in the crucible is heated and decomposed in a vacuum state by ultrahigh heat energy of electromagnetic waves (far infrared radiation). Further, vaporized gas is generated by this decomposition, which is sucked and discharged to the outside by the suction pipe. Therefore, the discharged gas can be cooled into a liquid, which can be disposed of or reused. Further, although the above-mentioned object to be treated is decomposed into ash in the crucible, it is taken out from the inside of the crucible by opening the opening / closing lid after the heat treatment. The ash taken out can be reused as a block or the like by solidifying it by a separate method.

According to the invention of claim 2, the above-mentioned claim 1
It works almost the same as the above item, but the gas generated in the crucible is led to the gas selection and extraction device outside the furnace main body by the suction pipe and the suction vacuum device, and the gas is sorted and sorted by type and liquefied. It can be disposed of or reused. Further, the gas that has not been extracted by the gas selection and extraction device returns to the heating device through the circulation path, where some of it is decomposed by high temperature and the other part is discharged from the exhaust stack. At that time, the gas passes through the exhaust pipe connected to the exhaust stack, becomes a harmless gas by the clean filter, and is discharged to the outside.

In addition to the function of the apparatus according to claim 1 or 2, the invention of claim 3 heats the crucible while rotating the furnace body. As a result, the heating device irradiates a wide area of the crucible evenly and heats the crucible more uniformly.
