In such a treatment system, when organic waste is separated, energy is recovered from the generated gas, while the pyrolysis residue generated by dry distillation is re-gasified in a melting facility or the like, or used for steelmaking. They are reused in electric furnaces.
[0004]
In the thermal decomposition system, waste is pulverized with a shredder and then subjected to thermal decomposition at a high temperature in a thermal decomposition furnace to separate organic pyrolysis gas and thermal decomposition residue.
[0005]
Generally, the pyrolysis residue that is discharged after gas is released from pyrolysis of refuse is mainly composed of carbon, ash, and metal contained in refuse that have not been gasified.
[0006]
As a recycling destination of the pyrolysis residue, secondary materials used in an electric furnace, auxiliary fuel of a cement kiln, and the like are promising.

[0030]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0031]
(First Embodiment)
FIG. 1 is a block diagram showing an example of the entire configuration of a thermal decomposition residue cleaning system according to the present embodiment. The same parts as those in FIG. 8 are denoted by the same reference numerals, and the description thereof will be omitted. State.
[0032]
That is, as shown in FIG. 1, the thermal decomposition residue cleaning system according to the present embodiment is provided with a processing target supplied from a waste thermal decomposition system that thermally decomposes various wastes including organic matter and recovers effective energy. Classifier 2 for sorting the thermal decomposition residue 1 as a product, a washing tank 4 provided with a washing tank for washing inorganic chloride in the sorted residue 3 supplied from the classifier 2, and a washing device 4 And a drying unit 6 for dehydrating and drying the post-cleaning residue 5 supplied from the cleaning unit. In the processing system shown in FIG. A degassing device 7 for vacuum degassing the post-sorting residue 3 after sorting supplied from the classifier 2 is installed.
[0033]
Next, the operation of the thermal decomposition residue cleaning system according to the present embodiment configured as described above will be described.
[0034]
In FIG. 1, the properties of the pyrolysis residue 1 are such that metal pieces, wires, debris, and the like are mixed in a wide range of powders and particles ranging from about 0.1 mm to several cm.
[0035]
In addition, most of the powders and particles in the pyrolysis residue 1 microscopically show a porous structure, and others include dense particles such as crushed glass. ing.
[0036]
The inorganic chloride to be removed by the thermal decomposition residue cleaning system is basically contained in the particles of the porous body, and the purpose of the present system is to remove the inorganic chloride by cleaning.
[0037]
As described above, since coarse metals and debris are mixed in the pyrolysis residue 1, the pyrolysis residue 1 is first put into the classifier 2 in order to sort them.
[0038]
The classifier 2 includes, for example, a vibrating wind separator, an inertia separator, and the like, and is selected according to the size and form of the metal.
[0039]
Since the pyrolysis residue 1 is a porous body having a very large number of micropores inside, when the residue 3 after classification is washed / extracted with a washing device 4 for inorganic chlorides, it is a simple stirring wash. In other words, the washing water 8 penetrates into the pores by capillary action.
[0040]
However, since most of the pores are open at one end, it is considered that it is difficult to reach the deep portion unless the air inside is replaced or discharged.
[0041]
Therefore, before the washing and extraction of the inorganic chlorides in the washing device 4, the residue 3 after classification is evacuated by the degassing device 7 to discharge the air in the pores (degassing), and then the washing solution is thinned. The washing water 8 penetrates into the hole.
[0042]
As a result, the inorganic chloride localized inside the particles can be efficiently washed and extracted.
[0043]
Then, the degassed residue is supplied to the cleaning device 4 and is cleaned and extracted with the cleaning water 8 for a period of about 30 minutes to remove the inorganic chloride.
[0044]
Since this inorganic chloride often exists in a water-soluble composition such as calcium chloride, water (wash water 8) is used as the washing liquid.
[0045]
In addition, since the inorganic chloride is localized inside the particles, and diffusion cleaning from the pores takes time, as the cleaning device 4, an immersion type cleaning device that disperses particles in a cleaning liquid is suitable. I have.
[0046]
On the other hand, as the amount of the washing water 8, an amount that does not reach saturation is used in consideration of the amount of the inorganic chloride contained and the solubility.
[0047]
In the case where heavy metals and the like are contained in the cleaning wastewater 9 and the wastewater treatment must be performed, the amount of water used is reduced to a water amount at which the cleaning efficiency does not decrease, and the load on the wastewater treatment system is reduced.
[0048]
The post-cleaning residue 5 extracted from the cleaning device 4 is sludge-like and has a very high water content, and cannot be used as a secondary material of an electric furnace or a cement auxiliary fuel as it is. It is dehydrated and dried to a few percent, and the residue after the treatment is set to 10.
[0049]
As described above, metals and the like are separated from the pyrolysis residue 1 by the classifier 2, vacuum degassed by the deaerator 7, and then washed by the cleaning device 4 to remove inorganic chloride in the pyrolysis residue 1. It becomes possible to remove efficiently, and the post-treatment residue 10 dried in the drying equipment 6 can be reused as an auxiliary material for an electric furnace or an auxiliary fuel for cement.
[0050]
As described above, in the thermal decomposition residue cleaning system according to the present embodiment, cleaning / extraction is performed by the cleaning device 4 after the permeation of the cleaning water 8 into the thermal decomposition residue is promoted by vacuum degassing before cleaning. Therefore, the inorganic chloride in the pyrolysis residue 1 can be efficiently removed with a simple structure and at low running cost to reduce the concentration to the required low level, thereby improving the quality as a recycled resource. It can be reused as auxiliary materials for electric furnaces and as auxiliary fuel for cement.

[0053]
Next, the operation of the thermal decomposition residue cleaning system according to the present embodiment configured as described above will be described.
[0054]
In FIG. 2, the residue 3 after classification after separating metals, debris, and the like is composed of powder and particles of various sizes, and large particles have a low rate of penetration or diffusion of the washing water 8 into the inside of the particles. Doing so is inefficient.
[0055]
In this regard, in the present embodiment, the residue 3 after classification is crushed into fine particles of about 0.5 mm or less by the crusher 11 installed at the subsequent stage of the classifier 2, thereby increasing the surface area and reducing the particle size. After homogenization, the residue after grinding is 12.
[0056]
As the crusher 11, for example, an impact-type crusher such as a hammer mill or a rod mill, or a crusher, which can easily crush brittle porous materials, can be used. It is preferable to select in consideration of metal.
[0057]
As described above, by washing the pulverized residue 12 atomized by the pulverizer 11 with the washing device 4, the inorganic chloride localized inside the particles can also be efficiently removed, The concentration of the residue 10 after the treatment can be reduced.
[0058]
