Description

  The present invention relates to a dielectric magnetic heat generating apparatus including a heating element that can generate heat by electromagnetic induction.

[First background]
In the field of incinerators for incinerating waste (general waste such as municipal waste and industrial waste such as shredder dust), the temperature in the furnace has been increased by burning fossil fuels such as heavy oil. A device is used that raises the waste and incinerates waste with the heat. However, in such an apparatus, incineration of waste is generally performed in a relatively low temperature range of about 800 ° C. Therefore, the chlorine compound contained in the waste is combined with other compounds, and the production of dioxins having strong carcinogenicity is promoted. In addition, such a type of device emits flue gas containing carbon dioxide and various toxic substances to the atmosphere during incineration of waste, which has a significant adverse effect on the global environment. Since the release of such environmental pollutants into the atmosphere has been steadily increasing with the development of industry in recent years, urgent action is required to prevent environmental pollution.

[Second background]
When fuel is burned in an internal combustion engine provided in an automobile or the like, exhaust gas containing a large amount of carbon dioxide and various harmful substances is generated. For this reason, there are concerns about the inhibition of the health of residents due to the exhaust gas discharged from internal combustion engines and the like, and the promotion of environmental destruction due to global warming.

  In recent years, catalysts and various filters have been provided in order to reduce the amount of harmful substances contained in the exhaust gas described above as much as possible. However, the action of reducing harmful substances by such a catalyst or filter is not always sufficient. Moreover, it is difficult to remove (decompose into harmless gas) carbon dioxide which causes global warming depending on the catalyst and filter currently provided. Therefore, it is strongly desired to provide an apparatus capable of detoxifying (or removing) harmful substances in exhaust gas and decomposing carbon dioxide.

[Third background]
Conventionally, power generation systems using thermal power and nuclear power have been used on a global scale. Such a conventional power generation system can sufficiently meet the demands of general households and various industries in terms of supplying power, but has a problem in terms of environment.

It has been. The rotating shaft 2 is rotated in the circumferential direction by a driving force transmitted from the motor 3 via a speed reduction mechanism or the like. And when the rotating shaft 5 rotates, the 1st refractory 5a and the heat generating body 4a rotate integrally in the circumferential direction with rotation of the said rotating shaft (FIG.2 and FIG.3). reference).

  According to such a feature, the entire heat treatment chamber can be uniformly maintained at an arbitrary temperature so that temperature unevenness does not occur in the heat treatment chamber 43. As a result, it becomes possible to perform the heat treatment uniformly and uniformly on the workpiece introduced into the heat treatment chamber 43. Therefore, for example, waste to be incinerated can be incinerated more efficiently. For example, environmental pollutants such as dioxin and carbon dioxide can be more efficiently burned and decomposed.

  The heating element 4a described above is formed of a material having conductivity and heat resistance (for example, molybdenum, tungsten, tantalum, etc.). The heating element 4a is formed of a double cylinder (double cylinder) in which a plurality of cylindrical bodies having different diameters (that is, the inner cylinder 41a and the outer cylinder 42a) are coaxially stacked. The inner cylinder 41a and the outer cylinder 42a forming the heat generating element 4a are integrated by an arm (not shown) that connects the outer wall of the inner cylinder 41a and the inner wall of the outer cylinder 42a.

As a result, for example, when the waste is incinerated in the heat treatment chamber 43, the waste can be efficiently incinerated.
In the present invention, the configuration of the heating element 4a is not necessarily limited to a double cylinder, and the heating element may be configured by a triple cylinder or a stack of more cylinders coaxially.

  As shown in FIG. 3, a temperature sensor 13 for measuring the temperature of the heat treatment chamber 43 is provided in the vicinity of the double cylindrical heating element 4 a. This temperature sensor 13 is electrically connected to a control circuit 10 described later.

  Around the double cylindrical heating element 4a, a second refractory 5b formed of the same material as the constituent material of the first refractory 5a is provided via a predetermined gap. Further, an induction heating coil 7 for electromagnetic induction heating of the heating element 4a is wound around the second refractory 5b, and the induction heating coil generates heat via the second refractory 5b. The periphery of the body 4a is surrounded.

  The induction heating coil 7 described above is electrically connected to a power source 9 capable of outputting an alternating current having an arbitrary frequency, and the power source 9 supplies a current having a predetermined frequency to the induction heating coil. ing. A control circuit 10 is connected to the power source 9, and the current supplied from the power source 9 to the induction heating coil is controlled in accordance with the measurement signal transmitted from the temperature sensor 10 described above.

  In the present invention, the cross-sectional shape of the induction heating coil 7 is not particularly limited, and may be square or round. However, in order to suppress an excessive temperature rise of the induction heating coil 7, it is preferable to form the induction heating coil 7 so as to have a hollow portion and to distribute the cooling water to the hollow portion.

[Refractories]
Next, details of the refractory used in the dielectric magnetic heat generator 1a of the present invention will be described.

The refractories 5a and 5b used in the dielectric magnetic heat generator 1a are generally manufactured through the following steps (1) to (4).
(1) Silica pearlite production process: A process for foaming silica stone to obtain silica pearlite having a particle diameter of 5 to 10 μm.
(2) Mixing and kneading step: Mixing and kneading the silicalite pearlite, sodium chloride, magnesium silicate, sodium salt, calcium powder, water, and, if necessary, metal powder such as chromium and molybdenum. Process to do.
(3) Molding step: A step for molding the mixed and kneaded kneaded product into a desired shape.
(4) Drying step: A step for drying the molded kneaded product.
Details of these steps will be described below.

1. Quartzite pearlite production process In the quartzite pearlite production process, first, quartzite as a raw material is prepared. Next, this quartzite is heated and foamed at a high temperature of 700 to 1300 ° C. Thereby, a quartzite perlite is generated.

2. Mixing / kneading process In the mixing / kneading process, the produced silica pearlite is mixed with sodium chloride, magnesium silicate, sodium salt, calcium powder, water, and as necessary using a mixer or the like. Mix and knead with metal powder such as chromium and molybdenum. When such a metal powder is used, it becomes possible to raise the heat-resistant temperature of the refractory to be manufactured.

In this process, the blending ratio of each raw material is as follows with respect to the total weight of the blended quartzite pearlite.
Sodium chloride: 10-20wt%
Magnesium silicate: 25-35 wt%
Sodium acid salt: 35 to 45 wt%
Calcium: 10-20wt%
Water: 50-150wt%
Metal powder such as chromium and molybdenum (mixed as necessary): 10-30wt%

3. Molding Step In the molding step, the kneaded product obtained through the mixing / kneading step is filled into, for example, a mold formed in the shape of a refractory to be manufactured. Next, this is pressed and formed into a desired shape. This pressing is performed at a pressure of about 1.5 to 16 kg / m ² , and preferably at a pressure of about 5 to 10 kg / m ² .

  Thus, by pressing the kneaded material filled in the mold, a refractory having a desired shape can be easily formed. Moreover, since the bonds between the particles of each substance become dense by pressing, the strength of the refractory after formation can be improved.

4). Drying step In the drying step, the kneaded product formed into a desired shape by the forming step is subjected to a drying process. This drying is generally performed by naturally drying the kneaded material after molding at room temperature for about 20 to 40 hours, preferably about 30 hours. This drying process may be performed while blowing hot air of 70 ° C. or less, preferably 45 to 50 ° C., as necessary.

  Through the above steps, a refractory (maximum refractory temperature: about 3000 ° C.) that can withstand long-time use under ultra-high temperature conditions is manufactured.

[Operation of dielectric magnetic heat generator]
Next, as an example of the heat treatment by the dielectric magnetic heat generation apparatus 1a, the operation of the dielectric magnetic heat generation apparatus 1a will be described by giving a case where waste is incinerated.

  When incinerating waste, first, an alternating current of an arbitrary frequency is supplied to the induction heating coil 7 by the power source 9. As a result, a current (eddy current) is generated near the surface of the heating element, and the heating element 4a rapidly self-heats due to the Joule heat.

  Next, when the heat treatment chamber 43 is heated to a predetermined temperature (about 2500 ° C.) by the heat generating element 4a that has generated heat, by rotating the rotating shaft 2, the heat generation element 4a (heat treatment chamber 43) is moved in the circumferential direction at a predetermined speed. Rotate (see FIG. 2). At the same time, while the heat treatment chamber 43 is maintained at about 2500 ° C., a predetermined amount of waste is continuously introduced into the heat treatment chamber 43 through the inlet 21. As a result, the waste is incinerated at an extremely high temperature.

  When the incineration is completed, finally, the incinerated waste (a slight residue or the like) is discharged from the heat treatment chamber 43 through the discharge port 22.

[Effect of dielectric magnetic heat generator]
Since the dielectric magnetic heat generator 1a of the present invention heats the heating element 4a and the heat treatment chamber 43 using the principle of electromagnetic induction, for example, a conventional incinerator takes several hours to start up to a high temperature. Compared to the above, the startup time can be considerably shortened.

  Moreover, since the dielectric magnetic heat generating apparatus 1a of the present invention heats the heat treatment chamber 43 using electric energy (the principle of electromagnetic induction), a conventional apparatus using fossil fuel such as heavy oil ( For example, compared to an incinerator, the amount of carbon dioxide generated can be reduced. As a result, environmental destruction due to a large amount of carbon dioxide can be drastically reduced.

  In addition, according to the dielectric magnetic heat generating apparatus 1a of the present invention, since the refractory material (maximum refractory temperature: about 3000 ° C.) formed from a predetermined material is provided, about 2500 ° C. without damaging the entire apparatus. Until this time, the heat treatment chamber 43 can be heated, and such an ultra-high temperature state can be maintained for a long time. And according to such a characteristic, the outstanding effect described in following (1)-(3) is achieved.

  (1) For example, when the dielectric magnetic heat generating device of the present invention is used in an apparatus for incinerating waste, the waste can be incinerated under extremely high temperature conditions (about 2500 ° C.). Most of the waste can be burned completely without causing harmful substances such as dioxins, odors, and dust. As a result, it is possible to incinerate the waste with almost no residue and without emitting harmful substances.

  (2) Also, for example, when the dielectric magnetic heat generator of the present invention is used in an apparatus for burning and decomposing environmental pollutants (for example, harmful substances contained in exhaust gas), it is heated to an extremely high temperature. By simply passing environmental pollutants through the heat treatment chamber, these pollutants can be easily burned and decomposed. Therefore, for example, when the apparatus of the present invention is provided in the middle of an exhaust passage (muffler or the like) connected to an internal combustion engine, most of the odorless / It becomes possible to burn and decompose into harmless gas.

  (3) Also, for example, when the dielectric magnetic heat generator of the present invention is used in an apparatus for high-temperature sterilization treatment of medical waste, pathogenic bacteria contained in the medical waste are treated under ultrahigh temperature conditions. Below, it becomes possible to kill them completely. As a result, used medical waste can be discarded without adversely affecting the environment.

As a result, a current (eddy current) is generated near the surface of the heating element 4, and each of the spherical heat generating portions 45e rapidly self-heats due to the Joule heat.

  Next, when the heat treatment chamber 43 reaches a predetermined temperature (about 2500 ° C.) by the heat generating element 4 that has generated heat, smoke is introduced into the heat treatment chamber 43 through the introduction port 21 and the through hole 51 while maintaining this temperature. Keep doing. The soot that has entered the heat treatment chamber 43 rises through the gap between the adjacent heat generating portions 45 that generate heat to a high temperature, and is burned and decomposed in an ultrahigh temperature atmosphere in the process. Finally, only the detoxified and non-brominated gas is discharged from the dielectric magnetic heat generator 1e through the discharge port 22.
