Waste specific configuration of the installation 10 is not shown, typically, the waste disposal facility 10, together comprising a melting furnace or incinerator and ash melting furnace therein, arising from these furnaces dust Is provided with a detoxification processing device for detoxifying the In addition, the detoxification treatment of dust is usually performed by melt solidification, cement solidification, chemical treatment, acid extraction treatment, or the like.
[0011]
Next, the configuration of the incineration ash final treatment facility 11 will be described in detail below.
As shown in FIGS. 1 and 2, the incineration ash final treatment facility 11 is composed of a main structure 12 and an incidental structure 13 constructed on the main structure 12, and the main structure 12 is partially or entirely ground. It is buried inside.
First, the main structure 12 will be described. A concrete pit 14 having a sealed box structure is embedded, and an incineration ash disposal chamber 15 is formed in the pit 14. At an intermediate position of the incineration ash disposal chamber 15, an intermediate stage 16 is installed over the entire width.
[0012]
The incineration ash disposal chamber 15 is divided into four incineration ash disposal spaces 17 in the lateral direction (pit width direction). A traverse rail 18 is disposed above each incineration ash disposal space 17, and a third rail in which the incineration ash storage bag 19 can be moved in the lateral direction and can be moved up and down in the traverse rail 18. A bag hanging crane 20 is attached.
A ceiling beam 21 is erected over the entire width of the upper part of the incineration ash disposal chamber 15. The transverse rail 18 is attached to a traveling rail 22 attached to the ceiling beam 21 in a direction perpendicular to the paper surface so as to be movable in the longitudinal direction (pit longitudinal direction).
[0013]
Between the intermediate stage 16 and the ceiling beam 21, a traverse rail 23 extending over substantially the entire width of the incineration ash disposal chamber 15 is laid, and the traverse rail 23 includes a first bag suspension crane 37 described later. A second bag suspension crane 24 that can horizontally transfer the incineration ash storage bag 19 transferred onto the intermediate stage 16 to above the incineration ash disposal space 17 is attached.
[0014]
Next, the structure of the incidental structure 13 will be described. An incinerated ash receiving space 26 is formed in the concrete wall structure 25 made of concrete. The other end of the incineration ash carry-in conveyor 27 whose one end communicates with the waste treatment facility 10 passes through one side wall of the surrounding wall structure 25 and enters the incineration ash receiving space 26. Specifically, the other end of the incineration ash carrying conveyor 27 is located at an upper inflow portion of a bifurcated chute 28 that is an example of an incineration ash filling device disposed in the incineration ash receiving space 26. The bifurcated chute 28 has two outlets 29 and 30 at the lower end thereof, and a flow path switching damper 31 at the upper inflow portion thereof.
On the ceiling beam 21 below the bifurcated chute 28, storage bag mounting tables 34 and 35 having load cells 32 and 33, respectively, are installed. An incineration ash storage bag 19 is mounted on each storage bag mounting table 34, 35, and its upper opening is located at the two outlets 29, 30 of the bifurcated chute 28.

[0017]
Dust detoxified by the debris and the detoxification processing device in the waste treatment facility 10 is continuously fed into the forked chute 28 using the incineration ash carry-in conveyor 27. The flow path switching damper 31 provided in the bifurcated chute 28 is operated to fill the incinerated ash in the incinerated ash storage bag 19 on the storage bag mounting tables 34 and 35 sequentially through the two outlets 29 and 30.
[0018]
The incinerated ash storage bag 19 is lifted from the storage bag mounting bases 34 and 35 using the first bag suspension crane 37, moved horizontally, then lowered, transferred onto the intermediate stage 16, and unloaded.
[0019]
After the incineration ash storage bag 19 is horizontally moved to one of the four incineration ash disposal spaces 17 using the second bag suspension crane 24, the cargo is unloaded onto the intermediate stage 16 again.
After the incineration ash storage bag 19 is transshipped to the third bag suspension crane 20, the incineration ash storage bag 19 is moved down to the desired position by moving down the incineration ash storage bag 19 and moving horizontally by a predetermined distance. Then, the disposal work is completed by unloading.
[0020]
By repeating the above operations, the incineration ash is smoothly conveyed from the waste treatment facility 10 to the incineration ash final treatment facility 11 using the incineration ash carry-in conveyor 27, and by using a large number of incineration ash storage bags 19 It can be disposed of efficiently in the incineration ash disposal chamber 15.
In addition, since the incineration ash is directly conveyed from the waste treatment facility 10 to the incineration ash final treatment facility 11 using the incineration ash carry-in conveyor 27, the incineration ash is scattered outside, unlike the case of using a dump truck or the like. Can be reliably prevented, and the final treatment of incinerated ash can be made pollution-free.
