2. Description of the Related Art Municipal refuse incineration ash has been designated as special municipal waste by the revision of the "Law on the Treatment and Cleaning of Waste" in 1992, and intermediate treatment is obligatory.
Examples of the intermediate treatment methods include an insolubilization treatment method using cement or a chemical, a melt solidification method using an electric furnace, and a solvent pouring method. In addition, "Baking" was added to the treatment method by the revision in 2000. Of these, the most common treatment method is to dispose at a controlled final treatment plant after insolubilization treatment with a cement solidifying agent or the like. However, there is now a shortage of final disposal sites, and measures are urgently needed. In addition, volume reduction by the melt-solidification method has been actively attempted, but even if volume reduction can be a measure to extend the life of a disposal site, it cannot be a fundamental solution. The biggest challenge in municipal solid waste incineration is how to recycle it.

While the waste passes through the rotary kiln 1, the heavy metal contained in the waste combines with the chlorine also contained in the heavy metal to become a volatile chloride, which together with the exhaust gas is discharged outside the rotary kiln 1. Is discharged. In addition, chlorine that has not been combined with heavy metals is combined with alkali or the like to form chlorides, which are volatilized and discharged to the outside of the rotary kiln 1 together with exhaust gas. Since the waste passes through the rotary kiln 1 for 60 to 90 minutes or more, the waste is fired in a state where the heavy metal and chlorine are sufficiently volatilized, and continuous treatment is possible. The firing temperature is 800 to 1500
° C, but in order to volatilize heavy metals such as Pb,
It is desirable that the temperature be 100 to 1500 ° C. Although the firing temperature is affected by the components of the waste, the firing temperature can be increased by, for example, adding limestone.

The waste from which the heavy metals and chlorine have been sufficiently removed by volatilization is fired in the rotary kiln 1 and granulated in a semi-molten state, thereby obtaining a granular fired product having a uniform particle size to some extent. After being cooled by the cooler 3, the fired product can be used as an aggregate for concrete or a roadbed material. When the particle size of the granular fired product is large, it can be roughly pulverized to a predetermined particle size using a general-purpose pulverizer, and this can be used as an aggregate. Alternatively, the granular fired product can be sieved with a general-purpose sieving apparatus, and a material having a predetermined particle size can be used as an aggregate, and the remainder can be returned to the rotary kiln 1 again. Furthermore, the granular fired product is first coarsely pulverized by a pulverizer, and then sieved by a sieve,
It is also possible to use the particles having a predetermined particle size as aggregate and return the remainder to the rotary kiln 1 again.

In the fired product, most of the heavy metal is volatilized, and a part of the heavy metal remaining therein is incorporated into the mineral generated by the firing and stabilized. Burned material in which heavy metals, chlorine and alkalis are volatilized from wastes containing heavy metals and chlorine,
It mainly becomes chloride dust and is collected by the dust collecting device 8.
Since the collected dust contains a high concentration of heavy metal, it can be recycled as a heavy metal product having a quality that can be provided as a raw material for heavy metal refining by treating it with a heavy metal concentrator 11 such as heavy metal extraction. It is possible.

In the dust discharged from the rotary kiln 1, a part of the input waste is scattered and mixed as it is. When a large amount of waste is scattered, the concentration of heavy metals in the dust collected by the dust collecting device 8 decreases, so that even if the heavy metal concentration treatment is performed, a quality that can withstand recycling cannot be ensured. . In that case, the dust is classified by the classifier 7 and the chloride dust having a fine particle size is finely divided into fine particles.
It is desirable to increase the concentration of heavy metals in the dust on the fine particle side by separating the coarse-grain dust into the coarse particle side. The dust on the coarse side is returned to the rotary kiln 1 again.

In recent years, recycling of municipal waste incineration ash has been attempted in various fields. According to the present invention, waste consisting of 100% municipal waste incineration ash can also be recycled as aggregate, which is extremely useful. Needless to say, it is waste disposal.
