Waste introduced into the main body 110 through the inlet 113 is heated to the outlet 114 side along the main body 110 by the transfer unit 114.

In addition, since the heat generating body 110 is made of a dielectric heating element, when microwave is irradiated from the microwave oscillator 113, a strong electric field is applied to the inside of the dielectric heating element, and the positive ion and negative electrons are generated in the heating body 110. The electromagnetic field made is aligned in the direction of the electric field, and when the electric field is applied in reverse, the electron band is also arranged in reverse. As the dipole rotation or vibration occurs in the molecule, heat is generated inside the main body 110 due to heat generation.

Therefore, waste that is transferred through the transfer unit 114 is pyrolyzed by heat generated in the main body 110 by heat generation. Here, since pyrolysis proceeds in an anoxic state because oxygen is not supplied to the pyrolysis space 111 of the main body 110 by heat generation, the residue of the pyrolyzed waste is collected through the outlet 114 by the transfer unit 114 (112). Transported and stored.

The microwave oscillator 113 for heating the main body 110 by the heat is cooled by blowing air in the oscillator cooling unit 116 so as not to overheat during the oscillation process of the microwave.

In addition, the gas generated in the process of pyrolysis of waste in the main body 110 and the gas generated in the residue of the waste collected in the collection box 112 are supplied to the combustor main body 172 through the gas supply pipe 171 and completely burned. do. The gas is supplied to the heating space 173 of the combustor main body 172 through the heating supply pipe, and moves toward the combustion section 174 while proceeding in a spiral direction from the heating space 173 through the spiral guide part 178. . The gas transferred to the combustion unit 174 is mixed with the air supplied into the combustor main body 172 through the air supply pipe 176, and is exploded while being heated to extremely high temperature by the electrodes 177 generating the glow discharge plasma. Combustion occurs. Gas and air to be combusted are injected to the outside of the combustor body 172 through the flame spray port (175).

The carbonization and pyrolysis gasification combustion apparatus 100 of the waste according to the present invention described above is not incinerated but by heating the body 110 by heat generation made of a dielectric heating element using a microwave in an anoxic state of 500 ~ 1600 ℃ Because of thermal pyrolysis method, the risk of fire or explosion accident can be lowered compared to the conventional incineration method, and the residue of the pyrolyzed waste does not smell and can be stored indoors.

In particular, industrial waste, hospital waste, and the like can fundamentally prevent secondary environmental pollution by completely burning pyrolysis gas by carbonization.

The present invention is widely applicable to various decomposition apparatuses using heat as well as carbonization or pyrolysis of various wastes.
