Description

  The present invention relates to an organic chlorine compound decomposing apparatus that decomposes a chlorine component before incineration of waste containing an organic chlorine compound such as vinyl chloride using a microwave, and particularly from an organic chlorine compound contained in plastic waste. The present invention relates to an organic chlorine compound decomposition apparatus for decomposing and removing chlorine components.

  It is extremely important to remove hydrogen chloride from plastic waste containing organic chlorine compounds such as vinyl chloride, which is an obstacle to the recycling technology of plastic waste, for example, as waste containing organic chlorine compounds. In general, dehydrochlorination treatment is possible by performing a combustion treatment at a temperature of about 800 ° C. or higher. However, the processing equipment becomes larger, the treatment time becomes longer, or the skeleton constituting the plastic in the heat treatment. There are disadvantages such as a large amount of decomposition products of substances.

  In addition, when these plastics are decomposed by heat treatment or subsequent heat treatment, there is a very high possibility that halogenated organic chlorine compounds exhibiting harmfulness are generated when the skeleton substance is decomposed. In particular, when the decomposition temperature becomes high or when a catalyst substance is mixed, these toxic organochlorine compounds are easily generated, and a large amount of toxic substances are generated from the dehydrochlorination step.

Of course, when plastics containing chlorine are burned, those organic chlorine compounds, such as dioxins and furans, are discharged from the combustion apparatus, so that they must be removed by decomposition or adsorption. In addition, regarding this type of prior art, for example, the following Patent Document 1 and Non-Patent Document 1 can be cited.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings of the examples.

  FIG. 1 is a cross-sectional view schematically illustrating a configuration of an organic chlorine compound decomposition apparatus according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a decomposition reaction container 2 containing, for example, activated carbon 3 as a decomposition substance 2 typified by plastic waste containing vinyl chloride having a low dielectric loss near normal temperature and a high dielectric loss substance. The inner wall surface of the container 1 is formed in a substantially pot shape by a metallic member that has been subjected to a surface processing process in which the microwave is difficult to absorb (is easily reflected) by microwave irradiation.

  Further, a sealable container lid 4 is attached to the upper part of the decomposition reaction container 1 so as to be opened and closed by remote control. Note that the inner surface of the container lid 4 is also formed of a metallic member that has been subjected to a surface processing treatment that makes it difficult for the microwave to be absorbed by the microwave irradiation and reflects it easily. A flexible hose 5 and a reaction exhaust gas recovery hose 6 capable of adjusting the atmosphere inside the decomposition reaction vessel 1 are coupled to the vessel lid 4. The reaction exhaust gas recovery hose 6 is coupled with an exhaust gas absorption processing device 7 for absorbing exhaust gas generated in the decomposition reaction vessel 1 due to thermal decomposition. Further, the container lid 4 is provided with a stirrer 8 for stirring a microwave to be described later that is irradiated into the decomposition reaction container 1, and is structured to be driven from the outside when the microwave is introduced.

  As the high dielectric loss material used here, a material that does not change into a low dielectric loss material by reacting with the gas generated by heating or the atmospheric gas being heated is selected. These high dielectric loss materials are required to be sufficiently safe for disposal as well as economical. Specifically, when microwaves are used for the dehydrochlorination reaction of vinyl chloride, a carbon material such as activated carbon 3 is optimal as a high dielectric loss material, and an inert atmosphere is formed by oxidation from the surface of activated carbon 3 as an atmosphere. Deterioration can be prevented.

  In addition, two sets of microwave generators 9a and 9b are connected to the side wall of the decomposition reaction vessel 1 through waveguides 10a and 10b, respectively. Further, in this decomposition reaction container 1, a container drive motor 11 for rotating and mixing the decomposition substance 2 and activated carbon 3 contained in the decomposition reaction container 1 in the circumferential direction is coupled to the rotation shaft 12 and the rotation shaft 12. The plurality of sets of transmission gears 13 are engaged and connected.

  In addition, these decomposition reaction containers 1 are installed together with the exhaust gas absorption processing device 7 on the installation surface 15 via the pedestal 14, and a recess 16 is provided on the lower side of the decomposition reaction container 1 on the installation surface 15. In the recess 16, a residue collection container 17 is disposed that stores a decomposition residue of the decomposition substance 2 decomposed in the decomposition reaction container 1.

  Next, a method for removing chlorine hydrogen from plastic waste containing an organic chlorine compound using the organic chlorine compound decomposition apparatus configured as described above will be described with reference to FIG.

  First, plastic waste containing an organic chlorine compound having a large shape was pulverized into a granular shape or about 10 mm square before the chlorine removal treatment of the plastic waste using the decomposition reaction vessel 1, and this pulverization treatment step was performed. To do later. Here, the reason why the plastic waste is preliminarily pulverized into a granular shape or about 10 mm square is that the decomposition material 3 described later and activated carbon 3 as a high dielectric loss material that easily absorbs microwave energy are added or the transmission described later. Although it is for making it the shape which the heat | fever generate | occur | produced from the activated carbon 3 arrange | positioned through the partition excellent in heat property is easy to heat-transfer, it is not necessarily limited to 10 mm square or less.

  As shown in FIG. 1, the decomposition lid 2 of the decomposition reaction container 1 is opened, and the decomposition substance 2 as plastic waste that has been previously crushed in the decomposition reaction container 1, and activated carbon 3 as a high dielectric loss substance, Then, the decomposition reaction vessel 1 is rotationally driven in the circumferential direction by the vessel drive motor 11, and the activated carbon 3 is appropriately dispersed and mixed. Next, after closing the container lid 4, the two sets of microwave generators 9 a and 9 b coupled to the decomposition reaction container 1 are operated alternately, and microwaves are introduced into the decomposition reaction container 1 from the waveguides 10 a and 10 b, respectively. A wave is introduced, and the decomposition substance 2 and the activated carbon 3 are uniformly irradiated with microwaves by the circumferential rotation of the reaction decomposition vessel 1 by the vessel drive motor 11 and the rotation of the stirrer 8.

  As a result, the activated carbon 3 absorbs microwave energy and is heated to a high temperature of about 100 ° C. or higher. The generated high heat is transferred from the activated carbon 3 to the decomposition material 2 which is a low dielectric loss material, and the decomposition material 2 is decomposed gas. While generating (hydrogen chloride gas), the temperature rises locally, and heat conduction is sequentially conducted to the periphery thereof, and the entire decomposition substance 2 is heated to a high temperature of about 100 ° C. or higher. As a result, the decomposition substance 2 which is a low dielectric substance that has been difficult to heat by microwave absorption can be easily heated by microwaves.

  Here, the decomposition substance 2 containing vinyl chloride, which is a low dielectric loss substance, has a low dielectric loss near room temperature. When the temperature is raised to a range of about 100 ° C. to 300 ° C., the dielectric loss increases rapidly. By the wave irradiation, the entire decomposed substance 2 is heated quickly and uniformly.

  The decomposition gas generated by the microwave irradiation is introduced into the exhaust gas absorption processing device 7 via the reaction exhaust gas recovery hose 6 coupled to the open / close lid 4. In this exhaust gas absorption processing device 7, an aqueous solution containing limestone and caustic soda is accommodated for the acidic exhaust gas, and the introduced exhaust gas is adsorbed with the acidic gas component in the exhaust gas by this aqueous solution. Removed. In addition, a decomposition gas (hydrogen chloride gas) component of the skeleton component of vinyl chloride that is partially generated and volatilized at a low temperature is simultaneously separated and captured by the exhaust gas absorption processing device 7.

  FIG. 2 shows the microwave energy absorption (= (microwave irradiation incident energy−reflected energy) × irradiation time) when activated carbon 3 is used as the high dielectric loss material, and the dehydrochlorination rate of vinyl chloride as the decomposition material 2 ( The relationship between hydrogen chloride in the decomposition residue and chlorine in vinyl chloride before decomposition (in terms of hydrogen chloride) is shown. As is clear from the figure, the inventors have experimented that chlorine hydrogen can be decomposed in a short time by making the addition amount of the activated carbon 3 approximately 25% or more with respect to the total amount of the decomposition substance 2. As a result, it became clear.

  According to such a configuration, the activated carbon 3 is added to the decomposition substance 2 to be decomposed and irradiated with microwaves to raise the temperature of the activated carbon 3 to a high temperature of about 100 ° C. to 300 ° C. Since the temperature of the decomposed substance 2 that is in contact is locally increased and heat conduction is performed quickly to the periphery thereof, heating of the entire decomposed substance 2 by microwave irradiation can be performed quickly and uniformly. .

  FIG. 3 is a cross-sectional view of an essential part of a decomposition reaction vessel schematically illustrating the constitution of another embodiment of the apparatus for decomposing an organic chlorine compound according to the present invention. The description is omitted. In FIG. 3, the difference from FIG. 1 is that a partition wall 18 made of fused silica glass having high heat conductivity and isolated from the bottom surface is disposed at the bottom of the decomposition reaction vessel 1. The activated carbon 3 which is a high dielectric loss material is accommodated. Therefore, the decomposition substance 2 is accommodated on the upper side of the partition wall 17.

  In such a configuration, activated carbon 3 stored in the bottom of the decomposition reaction vessel 1 is first heated by microwave irradiation, and the heat of the activated carbon 3 moves to the decomposition substance 2 side through the partition wall 18, thereby Without mixing 3 and the decomposed substance 2, the temperature of the decomposed substance 2 is raised and thermally decomposed, and dehydrochlorination of vinyl chloride by microwave irradiation becomes possible. As a result, the activated carbon 3 can be reused together with the decomposition substance 2 without being discarded in the residue collection container 17.

  FIG. 4 is a cross-sectional view of an essential part for schematically explaining the structure of still another embodiment of the organochlorine compound decomposition apparatus according to the present invention. The same parts as those in FIG. Description is omitted. 4 is different from FIG. 1 in that a gas introduction pipe 20 for introducing a gas (waste heat gas) having thermal energy such as exhaust gas discharged from the exhaust gas absorption processing device 7 into the container lid 4 and its waste. A gas discharge pipe 21 for discharging the hot exhaust gas is connected to each other, and a shutoff valve 22a and a shutoff valve 22b are connected to the gas introduction pipe 20 and the gas discharge pipe 21, respectively.

  Next, a method for removing chlorine from a plastic waste containing an organochlorine compound using the organochlorine compound decomposition apparatus constructed as described above will be described with reference to FIG.

  As shown in FIG. 4, the container lid 4 of the decomposition reaction container 1 is opened, and the decomposition substance 2 and the activated carbon 3 that have been previously pulverized in the decomposition reaction container 1 are appropriately dispersed and mixed and accommodated. Next, after closing the container lid 4, the shutoff valves 22 a and 22 b are opened, and a gas having thermal energy such as exhaust gas as waste heat gas generated in the exhaust gas absorption treatment device 7 is supplied into the decomposition reaction container 1. The decomposition substance 2 is heated to about 100 ° C. at which the dielectric loss reaches a predetermined level. The purpose is to preheat the decomposed substance 2 and any gas body having thermal energy may be used. Therefore, the present invention is not limited to the waste heat gas generated in the exhaust gas absorption processing device 7.

  Next, heating of the decomposition substance 2 is interrupted and the shut-off valves 22a and 22b are closed, and then two sets of microwave generators 9a and 9b coupled to the decomposition reaction vessel 1 are operated alternately, respectively, Microwaves are introduced into the decomposition reaction vessel 1 from 10a and 10b, and the decomposition substance 2 and the activated carbon 3 are uniformly irradiated by the rotation of the reaction decomposition vessel 1 in the circumferential direction by the vessel drive motor 11 and the rotation of the stirrer 8. To do.

  The cracked gas (hydrogen chloride gas) generated by the microwave irradiation is introduced into the exhaust gas absorption processing device 7 via the reaction exhaust gas recovery hose 6 coupled to the container lid 4. This exhaust gas absorption treatment device 7 contains an aqueous solution containing limestone and caustic soda for the acidic exhaust gas, and the introduced exhaust gas is adsorbed and removed by the acidic gas component in the exhaust gas by this aqueous solution. Is done. In addition, a decomposition gas (hydrogen chloride gas) component of a skeleton component of vinyl chloride that is partially generated and volatilized at a low temperature is simultaneously separated and captured by the exhaust gas absorption device 7.

  Finally, the decomposition substance 2 treated at a predetermined temperature for a predetermined time is stopped by microwave irradiation, the container lid 4 is opened, the decomposition residue in the decomposition reaction container 1 is taken out, and transferred to the residue collection container 17 to complete the decomposition. To do.

  In such a configuration, vinyl chloride, which becomes an obstacle when reusing the decomposed material 2 as plastic waste exhibiting low dielectric loss near room temperature, has a low dielectric loss near room temperature, from about 100 ° C. or more. The dielectric loss increases rapidly and can be easily heated by microwave irradiation. In the decomposition of the decomposition substance 2 having such characteristics, a low-temperature exhaust gas as waste heat gas discharged from the exhaust gas absorption device 7 before microwave irradiation is introduced into the decomposition reaction vessel 1 and about 100 ° C. It is possible to increase the absorption rate of the microwave energy of the decomposition substance 2 by preheating up to and then irradiating with microwaves. This enables efficient thermal decomposition by microwave irradiation at low temperatures,

  FIG. 5 is a cross-sectional view of an essential part of a decomposition reaction vessel for schematically explaining the constitution of another embodiment of the apparatus for decomposing an organic chlorine compound according to the present invention. The same parts as those in FIG. The description is omitted. In FIG. 5, a difference from FIG. 1 is that a holding container 23 made of, for example, a ferrite material is disposed as a high dielectric loss member at the bottom of the decomposition reaction container 1, and the upper part of the holding container 23 has a low dielectric loss. Decomposed material 2 'is accommodated. In this case, as the decomposition substance 2 ′, the plastic waste containing the organic chlorine compound having a large shape is not crushed, and the container lid 4 is opened and stored in the upper part of the holding container 23 while maintaining the shape as it is. .

  In such a configuration, the holding container 23 disposed at the bottom of the decomposition reaction container 1 is first heated by microwave irradiation, and the heat of the holding container 23 is directly transferred to the decomposition substance 2 ′. Thus, without mixing the above-described activated carbon with the decomposition substance 2 ′, the temperature of the decomposition substance 2 ′ is increased and thermally decomposed, and dehydrochlorination of vinyl chloride by microwave irradiation becomes possible.

  According to such a configuration, the decomposing substance 2 ′ can be accommodated in a large shape without being pulverized in advance and dehydrochlorinated, and the decomposing residue of the decomposing substance 2 ′ subjected to dehydrochlorination is directly taken out. Therefore, the pulverizing step of the decomposed substance 2 ′ that has been performed in advance can be made unnecessary.

Fig. 6 shows the dehydrochlorination method by thermal decomposition from ordinary vinyl chloride, simple microwave irradiation method, microwave irradiation method with high dielectric loss substance added, and microwave irradiation method with preheating microwave irradiation method. It is the figure shown about the decomposition amount of frame | skeleton material. In FIG. 6, the heating method is thermal decomposition from ordinary vinyl chloride, the microwave irradiation method alone irradiation method is a simple microwave irradiation method, the high dielectric loss material usage method is a microwave irradiation method with a high dielectric loss material added, The preheating method indicates a microwave irradiation method in which preheating is performed. The same applies to FIGS. 7 and 8 below. As is apparent from FIG. 6, the amount of decomposition of the skeletal material can be reduced by microwave irradiation even with the same dehydrochlorination rate by microwave irradiation.

  FIG. 7 shows a comparison of energy used for the four types of dehydrochlorination techniques described in FIG. As is clear from FIG. 7, especially in the pre-heating type microwave irradiation, since the pre-heating method uses low-temperature exhaust gas, substantially necessary energy can be ignored (no cost as decomposition energy). It can be processed with lower energy compared to other dehydrochlorination techniques.

  FIG. 8 shows a comparison of decomposition times in the four types of dehydrochlorination methods described above. As can be seen from FIG. 8, the pre-preheating method is also very advantageous here.

  In each of the above-described embodiments, the case where activated carbon is used as the high dielectric loss material has been described. However, the present invention is not limited to this, and a ferrite material may be used instead of activated carbon. Similar effects can be obtained.
