Description

Processing equipment for solids containing harmful substances such as organic halogen compounds

The present invention relates to a solid processing apparatus containing a toxic substance such as an organic halogen compound, and in particular, by irradiating a solid containing a toxic substance such as an organic halogen compound with microwaves, the toxic substance such as an organic halogen compound is removed. The present invention relates to a solid processing apparatus containing a harmful substance such as an organic halogen compound that is decomposed.

Dust collection ash discharged from municipal waste incinerators and electric furnaces and collected by dust collectors contains harmful substances such as organic halogen compounds such as dioxins. The ash was solidified by an ash solidifying device or the like to prevent elution of harmful substances such as organic halogen compounds, and then was subjected to processing such as landfilling.

On the other hand, for the purpose of minimizing the adverse effects of dioxins on the human body, in December 2002, “Ministerial Ordinance on Standards and Measurement Methods for the Amount of Dioxins Contained in Soot and Dust in Waste Incinerators” Since 1st, there is a restriction on the concentration of dioxins contained in dust collection ash to be 3 nanograms or less per gram of dust collection ash, and measures to remove dioxins from dust collection ash It became necessary to apply.

In order to comply with this regulation, the dust collection ash is heated in an oxygen-deficient state at 350 ° C. or higher, preferably 400 ° C. or higher for 30 minutes or longer, and further heated to 200 ° C. or lower after heating to prevent resynthesis. It has been proposed and put to practical use a method of cooling or decomposing harmful substances such as organic halogen compounds such as dioxins by irradiating the dust collection ash with microwaves (for example, Patent Documents 1 to 3). reference).

The applicant previously proposed a solid processing apparatus containing a harmful substance such as an organic halogen compound in Japanese Patent Application No. 2005-353936.
As shown in FIG. 3, this solid processing apparatus containing a harmful substance such as an organic halogen compound has a casing for introducing a solid containing a harmful substance such as an organic halogen compound (hereinafter referred to as “pollutant”). 30 and a microwave processing device 3 provided with a microwave irradiation mechanism 31 for irradiating a solid containing a harmful substance introduced into the housing 30 with a microwave. Contaminants discharged from a dust collector or the like are transferred by the transport device 4 and introduced into the housing 30 from the discharge port 4a through the introduction port 3a disposed in the upper portion of the housing 30. Then, microwaves are irradiated from a microwave irradiation mechanism 31 disposed at an appropriate position of the housing 30 to perform decomposition processing of harmful substances such as dehalogenation reaction of organic halogen compounds contained in the pollutants. Thereafter, the contaminants treated by the transport device 5 are discharged through the discharge port 3b disposed in the lower portion of the housing 30. In this case, since the planar cross-sectional shape of the peripheral wall of the upper half of the housing 30 is formed to be a pentagon or more polygon, the microwaves reflected by the inner wall surface of the housing 30 are concentrated on a specific location. And there is an advantage that the microwave can be uniformly irradiated to the pollutant.

By the way, when the microwave irradiation mechanism 31 irradiates the microwave, the moisture contained in the pollutant is heated by the microwave and is evaporated in the state containing the harmful substance in the housing 30 to become exhaust gas and become an exhaust pipe. 6 is discharged to the outside of the housing 30 via 6. In general, the microwave treatment method is not suitable for decomposing harmful substances such as organic halogen compounds contained in gas or water, and therefore, harmful substances such as organic halogen compounds contained in evaporated exhaust gas are discharged. The adsorption treatment is performed by a filter 61 such as a ceramic filter disposed in the pipe 6 or an activated carbon filter provided on the downstream side of the discharge pipe 6.

However, when the pollutants to be treated are soils with high moisture content, rivers, bottom sediments, etc., the moisture content is a value of several tens of percent. In addition to the problem that much energy is consumed for evaporation of residual moisture as described above, the amount of exhaust gas generated by microwave heating increases, and the filter 61, activated carbon filter, etc. There was a problem that the adsorption treatment could not be performed and sufficient exhaust gas treatment could not be performed.
Further, depending on the filter 61, the activated carbon filter, etc., only harmful substances such as organic halogen compounds are adsorbed, and these harmful substances cannot be decomposed.

Although it has been proposed to decompose harmful substances such as organic halogen compounds with ultraviolet rays (see, for example, Patent Documents 4 to 5), all of these treat harmful substances such as organic halogen compounds alone. However, it was unrelated to the solid processing apparatus containing harmful substances such as organic halogen compounds.

In recent years, detoxification treatment of soil and sediment has been carried out by solid treatment equipment containing harmful substances such as organic halogen compounds.
However, soil and sediment contain a large amount of moisture, and conventional solid processing equipment containing harmful substances such as organic halogen compounds consumes a lot of energy to evaporate the contained moisture, making it uneconomical. Yes.

Specifically, in a conventional solid processing apparatus containing a harmful substance such as an organic halogen compound, the processing is performed only by natural exhaust without particularly sucking the generated exhaust gas.
For this reason, only a part of the evaporated water is discharged, and most of it stays in the housing of the solid processing equipment containing harmful substances such as organic halogen compounds, and condenses on the inner wall after the operation is stopped. Then it becomes moisture again.
Soil with high moisture content, sediments such as rivers and seabeds have a moisture content of several tens of percent, and when microwave heat treatment is performed, the absorption of microwaves by water is very high. Therefore, the present situation is that much energy is spent on evaporation of the remaining water as described above.

JP 2000-334062 A Japanese Patent Laid-Open No. 2001-19646 JP 2005-169291 A Japanese Patent No. 3461312 JP 2004-321917 A

In addition to being able to be decomposed by ultraviolet rays, harmful substances such as organic halogen compounds adhering to the surface of the solid can be decomposed.

In addition, by disposing the ultraviolet irradiation mechanism inside the exhaust pipe that discharges the exhaust gas generated in the housing, the exhaust gas discharged outside the housing can be effectively detoxified, and the ultraviolet irradiation mechanism can be It can be disposed at a relatively low temperature position in the casing that becomes high temperature due to heating due to heat, and it is possible to prevent deterioration or failure of the ultraviolet irradiation mechanism due to heat.

In addition, by using an electrodeless lamp for the ultraviolet irradiation mechanism, it is possible to generate ultraviolet light by an electromagnetic field generated by the microwaves irradiated in the housing, and there is no need to provide a separate power supply facility for the ultraviolet irradiation mechanism. The cost of the apparatus can be reduced.

The solid processing apparatus containing a toxic substance such as an organic halogen compound according to the present invention includes a casing for introducing a solid containing a toxic substance such as an organic halogen compound, and a solid containing a toxic substance introduced into the casing.

It is possible to improve on.
Further, since the water vapor to be exhausted can pass through the filter in a gaseous state, it is possible to perform an efficient adsorption treatment of organic substances and harmful substances in the exhaust gas.
