It burns in the evaporation space (97) and near the surface of the lower partition member (91a). As described above, most of the organic wastewater evaporates and burns in a relatively low-temperature (around 200 ° C.) atmosphere without being exposed to a high temperature, and thus does not cause generation of peroxides or modification due to chemical polymerization. Generally, harmful gases such as NOx are generated during high-temperature combustion exceeding 600 ° C., and hardly occur under the above-mentioned low-temperature conditions.

す。The organic wastewater evaporated by the contact with the low-temperature gas is heated by the upper layered wire mesh (91b), and is appropriately heated by the upper burner (93b) in the deodorizing space (99) above the wire mesh (91b). Temperature (for example, about 500 ° C.). As a result, smoke and odorous substances generated below are burned, and the exhaust gas discharged from the chimney (94) is smokeless and odorless. Since the upper partition member (91b) also exerts a rectifying effect on the combustion gas, it prevents uneven heating in the deodorizing space (99) and greatly contributes to smokeless and odorless exhaust gas. In addition, the partition member (91b) is used to remove the organic matter flammable in the evaporation space (97) but the deodorant space (99).
Also acts as a filter to prevent intrusion into the system.

It becomes possible. The ash after combustion passes through the lower laminated wire mesh (91a) and accumulates on the floor plate (102) of the furnace body (90), and is periodically discharged from manholes (103) provided in the furnace body (90). . This manhole (103) also serves as an inspection window in the furnace.
