No. 219 discloses that exhaust gas generated in an incineration ash melting treatment facility is cooled by a cooling device, then dust in the exhaust gas is separated by a dust collector, and water, ferrous chloride and the like are added to the separated dust and kneaded. Thus, a method for immobilizing hexavalent chromium is described. Heretofore, there is no document which describes a structure in which a reducing exhaust gas from an ash melting furnace is reburned and then cooled, and the reburning equipment and the cooling equipment are integrally provided.

オキシンの再合成を引き起こしやすかった。In the conventional equipment having a long residence time of exhaust gas as shown in FIG. 12, since volatile substances in the exhaust gas cannot be rapidly cooled, it is selected as dust in a temperature range where these substances condense. It eventually accumulates in the flue and eventually leads to blockage of the flue. Further, if the residence time of the exhaust gas is long, the exhaust gas cannot pass through the dioxin resynthesis temperature range in a short time, so that harmful dioxins are easily resynthesized.

スの滞留時間を短くすることができる。The reducing exhaust gas discharged from the ash melting furnace 10 is blown into the combustion air from an air blowing nozzle 24 near the burner 22 and recombusted. When the exhaust gas temperature at the inlet of the reburning / cooling tower 20 is low, the burner 22 is used as an auxiliary device for the reburning. Next, the reburned exhaust gas is blown with cooling air from an air blowing nozzle 24 located above the burner 22, and is cooled by air. This is the reburn / first cooling zone 25. The exhaust gas cooled by air is sprayed with water for cooling from a water spray nozzle 26 provided in the second cooling zone 27 in the upper stage, and rapid cooling with water is performed this time. As described above, since the exhaust gas is rapidly processed by the reburning / cooling tower 10 integrally provided with the reburning equipment and the cooling equipment, the residence time of the exhaust gas can be shortened.

(1) Since the reburning facility and the cooling facility are integrally provided, the reducing exhaust gas discharged from the ash melting furnace can be reburned instantaneously and efficiently, and rapidly and reliably quenched.
Outflow of unburned gas can also be prevented. (2) Since the residence time of the exhaust gas is short, the exhaust gas can pass through the reducing gas temperature range and the dioxin resynthesis temperature range in a short time. Therefore, it is possible to prevent the flue from being blocked by dust and to reduce the dioxin concentration. (3) Since the reburning and cooling of the exhaust gas can be performed instantaneously and efficiently, the flue distance in the processing apparatus can be largely reduced.
