Abstract

PURPOSE:To improve heat efficiency and to conduct efficient combustion of offensive smell gas, by a method wherein the air in an air feed pipe is heated at the inside of a deodorizing tube, and a part of the heated air is blown off to the deodorizing tube and a plasma torch. CONSTITUTION:Microwave is fed through a microwave transmission coaxial tube 9 from a microwave oscillating source 8, and meanwhile, the air is fed through air feed pipes 6 and 6b from a blower 7. Air is heated by a preheater 5 at a starting time and is heated by combustion heat during the operation, a part thereof is blown into a deodorizing tube 3 through a supply opening 6a, and the rest passing through a branch air feed pipe 6b is fed to the plasma torch 10. The heated air fed to the plasma torch 10 is activated by a microwave field generated between an electrode 12 and a nozzle 13 to form a plasma flame which is blown against a substance 2 to be incinerated in a combustion chamber 1. This improves a heat efficiency and causes to perform an efficient deodorization of offensive smell gas.

Microwaves are sent from the microwave oscillator 8 through the microwave transmission coaxial pipe 9, while air is sent from the blower 7 through the air pipes 5, 5b'2. The air is heated by the preheater 5 at the time of startup and by the combustion heat during operation, and a part of it is blown out from the outlet 7 6a into the odor cylinder 3, and the song is branched air fan '+f6.

る。Thus, the heated air obtains energy from the microwave electric field, becomes a plasma flame 14, reacts with the odor residue generated from the material to be incinerated 2, burns and deodorizes it, and is further transferred to the material to be incinerated. It becomes a heat image that is blown and releases active energy to thermally decompose the material to be incinerated 2. Although some unburned odor residue is scattered due to the air flow directed at the M incineration material 2, it is completely combusted by the activated air around the outer circumference of the plasma flame 14 and the heated air blown out from the air outlet 6a. It is made odorless and is discharged from the exhaust stack 4. The highly wet exhaust gas heats the air in the blower pipe 6 in the spring extinguisher cylinder 3 by +1
bj, where it undergoes heat exchange and is discharged as a narrow width.

焼させることができる。As explained above, the present invention heats the air in the blower pipe 6 in the deodorizing tube 3 which is an exhaust passage, so thermal efficiency is good and a part of the heated air is heated inside the deodorizing tube 3/deodorizing tube 3. Since it is blown out, unburned odor residue is decomposed inside the deodorizing cylinder and becomes odorless. Also, part of the heated air song is burned as plasma flame 14 from plasma torch 10.
Since the combustion chamber 1 is blown out into the combustion chamber 1, it is possible to efficiently heat and burn the odor dregs generated from the incineration object 2 and the debris in the combustion chamber 1.
