[0009]
During the traveling of the first trailer 1, the rotary kiln 12 is fixed by a spring pressing means (not shown), and the fixing is released and becomes rotatable during on-site processing.
[0010]
In FIG. 1 and FIG. 3, the second trailer 2 includes a cooling tower 21 that cools a gas (hereinafter referred to as post-reburning gas) that has passed through the reburning furnace connected to the reburning furnace 14 by a connection pipe 3. The bag filter 22 is installed behind the cooling tower 21 and removes dust mixed in the gas passing through the cooling tower 21 (hereinafter referred to as gas after cooling), and installed behind the bag filter 22. , An induction blower 23 that attracts gas (hereinafter referred to as “after-graduation gas”) that passes through the bag filter 22 and a chimney 24 that is installed behind the induction blower 23 and releases the gas after dust removal to the atmosphere. It is mounted and each is connected by piping.
[0011]
While the second trailer 2 is traveling, the cooling tower 21 falls and its height decreases, and the chimney 24 also falls. Therefore, it is possible to carry on-site processing equipment to the site without being restricted by traffic restrictions in urban areas such as the passable height of the gates that pass.
[0012]
FIG. 4 is a sectional view showing a connection state of the first trailer 1 and the second trailer in the embodiment of the on-site treatment apparatus for dioxin contaminants according to the present invention. In FIG. 4, the reburning furnace 14 placed on the first trailer 1 and the cooling tower 21 placed on the second trailer 2 are connected by a connecting pipe 3.
[0013]
Accordingly, dioxin contaminants are thermally decomposed and rendered harmless in the rotary kiln 12 and discharged, while the combustion gas provided thereto is released into the atmosphere after being cooled and gradually diffused. It becomes possible to complete the treatment process locally.
[0014]
Note that the chimney 24 may be changed over freely, and a plurality of cylinders having different inner and outer diameters may slide to expand and contract.
