2. Description of the Related Art Municipal garbage and industrial waste, which increase year by year,
Some incinerators, such as gas burners and heavy oil burners, are incinerated, but the incombustibles contained therein remain as residues, and the residues are discarded in dedicated dumps. It is a major social problem as a land problem and a pollution problem.

[0003] In such a conventional combustion type incinerator, the incineration material is put into a combustion chamber lined with refractory material and heated by a combustion burner for incineration. Since minerals cannot be incinerated, the amount of residue increases and the volume reduction rate is low, and as mentioned above, dumping has become a problem.

[0004] Since the non-combustible material that remains as such can be further reduced in volume by melting at a high temperature,
A method of melting in an electric furnace such as an arc furnace, a resistance furnace, or a plasma furnace, an oxygen reactor, or the like has also been proposed. In this case, the residue to be melted is thrown into a crucible-shaped melting chamber constructed of bricks and irregular-shaped refractory material and heated and melted, but the heating temperature must be 1700 ° C or less, which is the refractory temperature of the refractory material . As described above, there is a metal as a residue having a melting point of 1700 ° C or less, but among the incombustible residue, there are few metals and most are mineral substances similar to the furnace wall refractory material. Could not be melted.

Further, since the melting chamber is a crucible, the size of the crucible is limited in terms of the crucible manufacturing technique. The molten residue must be discharged in a liquid state. However, there is a problem that it cannot be used as it is and the molten component cannot be separated.

In the residue melting furnace of the present invention, a mixture of incombustible residue and a graphite block is charged into a melting chamber, and then the inert gas is supplied from an inert gas supply pipe into the melting chamber while the core is supplied from a high frequency power supply. An alternating current is applied to the coil wound around the legs of the U-shaped iron core to generate Joule heat in the graphite block.
As a result, the non-combustible residue in contact with the graphite block heated to a high temperature in the inert gas atmosphere is also heated and melted. The molten incombustible residue becomes liquid and is dropped into water in a water tank disposed below, where it is quenched and recovered as a sandy solid.

Connect them together at 14. Next, the ceiling surface 5b of the melting chamber 5 is opened, and a mixture of the non-combustible residue 9 and the graphite block 8 is charged from the charging port. Next, the melting chamber 5 is moved and installed between the legs 3 of the inductor 1.

Next, when an alternating current is applied to the coil 4 from a high-frequency power supply (not shown) while supplying an inert gas such as an argon gas into the melting chamber 5 from the inert gas supply pipe 7, the opposed iron core legs 3, 3 A strong magnetic flux 15 is generated in between. The magnetic flux 15 penetrates through the melting chamber 5 and interlinks with the graphite block 8 inside, so that an induced current flows, and an eddy current loss is generated from the specific resistance of the graphite block 8 and the induced current, thereby generating Joule heat to generate the graphite block. 8 generates heat. As a result, the incombustible residue 9 in contact with the high-temperature graphite block 8 is also indirectly heated, and since the inside of the melting chamber 5 is maintained in an inert gas atmosphere, the graphite block 8 does not oxidize and burn at 2000 ° C. By raising the temperature to the extent, most of the non-combustible residue 9 can be melted.

The melted incombustible residue 9 becomes liquid and drops into the water 13 of the water tank 12 disposed below from the gap between the graphite chips 10, where it is rapidly cooled to a sand-like solid 16. in this case,
Since the melting point differs depending on the type of the substance contained in the incombustible residue 9, the obtained sand-like solid 16 is formed with almost the same melting point. Since the solids 16 are in the form of solids, they can be effectively used by sorting them out according to the difference in specific gravity. Further, since the side surface 5a of the melting chamber 5 is formed with the uneven portion 6, the eddy current of the induced current generated by the magnetic flux 15 interlinking with the side surface 5a can be prevented, and the heat generation of the side surface 5a itself can be suppressed. It has become.

A plurality of units which can be moved by attaching 17 are prepared, and the melting chamber 5 is slowly moved between the inductors 1 to sequentially melt the incombustible residue 9 in the melting chamber 5 along the longitudinal direction. I'm going to go. When the melting in one melting chamber 5 is completed, the melting chamber 5 is drawn out of the inductor 1 and the other waiting melting chamber 5 is moved into the inductor 1 so that the processing can be efficiently performed without stopping the operation. .
