Description

  TECHNICAL FIELD The present invention relates to a method and an apparatus for producing waste carbide and plastic-containing solid fuel, in which solid fuel is produced using, as main raw materials, carbide and plastic generated by thermal decomposition treatment of waste such as municipal waste.

  In recent years, among the methods for treating combustible waste, as an alternative to the combustion method in which waste is burned in an incinerator, it has been proposed to recycle and use it as a resource by processing the waste As one of the resource recycling of such waste, there is a so-called thermal recycling in which the combustible component in the waste is reused as fuel (heat source).

One of the methods proposed to reuse the combustible components in this kind of waste as fuel is to crush, sort, compress, etc., using municipal waste and other waste (general waste) as raw materials. Through the process, the waste solidified fuel (Refuse Derived Fuel: hereinafter referred to as RDF) is manufactured.
Some DFs are stored and transported as necessary, and used as fuel in power generation and other various combustion furnaces (incinerators). However, since the raw material used for the RDF is general waste, there is a large variation in composition, and therefore, the amount of heat generated during combustion may become unstable, and it is difficult to stabilize the quality. It was said. Moreover, since there is a concern about the problem of spoilage when the general waste as a raw material contains moss and the like, it has been necessary to adjust pH by adding lime or the like separately. Furthermore, if the raw material contains chlorine-containing plastics such as vinyl chloride, there is a concern that hydrogen chloride gas and dioxins may be generated at the time of combustion. . Moreover, since the calorific value at the time of combustion is relatively low, the actual value is that the utility value as fuel is not so high.

  For this reason, as a method for using a combustible component in waste to produce a fuel with a higher calorific value, paper as industrial waste with a clearer emission source than the above general waste such as municipal waste (Recycled paper) and plastics (waste plastics), and waste paper and waste plastics selected from general wastes as raw materials to produce high-calorific solid fuels (RPF: Refuse Paper & Plastic Fuel) have attracted attention in recent years It is coming.

  The RPF is, for example, crushed waste paper that is difficult to recycle and waste plastic from which chlorine-containing plastics such as vinyl chloride have been removed, and then mixed to obtain a mixture of the waste paper crushed piece and waste plastic crushed piece into a required shape. It is designed to be manufactured by extrusion molding (compression molding). Thereby, due to the use of a relatively stable raw material of waste paper and waste plastic, the RPF can stabilize the quality as a fuel and eliminate the possibility of corruption, Since it contains plastic, the amount of heat can be increased to the extent that it can be used as an alternative fuel for fossil fuel, and the utility value as fuel can be increased. Furthermore, it is also possible to adjust the calorific value by changing the mixing ratio of waste paper and waste plastic.

  Furthermore, in addition to the waste paper and waste plastics similar to the RPF, the following methods have also been proposed as methods for converting to solid fuel using a wider range of combustible waste as a raw material. That is, as shown in FIG. 3 and FIG. 4, combustible waste (waste) a as typified mainly by household waste is firstly converted into a carbonization device (pyrolysis furnace) (not shown) in the carbonization step ST1. ) And carbonized by steaming to make trash char (carbide) b. Next, in the mixing step ST2, the garbage charcoal b, waste plastic c, and waste paper d are mixed at a predetermined weight ratio, and then the mixture is crushed to a required size in the crushing step ST3. Subsequently, in the compression step ST4, the obtained crushed material is compressed until the waste plastic c contained by the frictional heat generated by the compression is softened, and the compressed product is sized. In ST5, the particles are sized (molded) into a required shape to form a solid fuel.

  Specifically, the compression step ST4 and the granulation step ST5 are performed by one compression / granulation device e as shown in FIG. That is, a compression / granulation apparatus e shown in FIG. 4 is inscribed in a rotating drum-shaped die (ring die) g having a large number of die holes h in a peripheral wall surface in a casing f and the die g. The rollers i and j that support and rotate the die g, the cutter k disposed along the outer peripheral surface of the die g, and the crushed material l crushed in the crushing step ST3 to the inside of the die g. It is composed of an input duct m to be input. As a result, the crushed material l introduced into the inside of the die g through the introduction duct m is pushed into the die hole h by being strongly pressed by the rollers i and j, and the crushed material is generated by the heat generated by the frictional heat generated at this time. l The softened pieces of waste plastic c contained in l are softened and integrated with the pieces of waste charcoal b and waste paper d, and at the same time, along with the pushing into the die hole h, The crushed material l that has already entered the die hole h is extruded so as to protrude from the die hole h to the outer peripheral side of the die g, and the crushed material l of this protruding portion is cut by the cutter k, Solid fuel (mixed fuel of carbonized waste and paper / plastic: C-RPF) n having a constant diameter and a fixed length is manufactured (see, for example, Patent Document 1). ).

  By the way, the applicant has previously disposed of the pyrolysis furnace from the dust feeder so that solid fuel (RDF) can be produced from char (carbide) after pyrolyzing the waste such as municipal waste. The waste is indirectly heated and dried by external heat in an inert atmosphere in a pyrolysis furnace, thermally decomposed, and then from the separation chamber serving as the outlet of the pyrolysis furnace. Take out char as a pyrolysis residue, then add 10-30% moisture to the char after removing large incombustibles and metals, knead, and then compression-mold the required shape by compression molding A method is proposed in which a solid fuel (RDF) is obtained by making a product and then curing the compression-molded product by forced air cooling (see, for example, Patent Document 2).

JP 2001-240882 A JP 2001-271080 A

  However, what is described in Patent Document 1 is that solid charcoal (carbide) b generated by carbonization of combustible waste (waste) a is solid fuel n in a state of light flakes or powders. The solid fuel n is manufactured by being transported for manufacturing.

  In addition, what is described in Patent Document 2 is a method of converting solid waste into a solid fuel by using only char (carbide) after pyrolyzing the waste as a raw material, but converting the char into a solid fuel together with other materials. The idea is not shown at all and is not even suggested.

  Then, this invention pushes further what is indicated in patent documents 1, and in the manufacture process of the waste carbide and the plastic containing solid fuel as a product manufactured using waste carbide and waste plastic as the main raw materials. This makes it easier to transport the waste carbides and allows better mixing with the plastics to increase the homogeneity of the individual particles of the product waste carbides and the plastic-containing solid fuel. Thus, an object of the present invention is to provide a method and an apparatus for producing waste carbonized and plastic-containing solid fuel that can be expected to improve the combustibility as a fuel.

In order to solve the above problems, the present invention provides a step of pulverizing a carbide obtained by pyrolyzing a waste in a pyrolysis furnace, a step of conditioning the pulverized carbide, and the humidity conditioning. carbides, plastics and Luke mixed by crushing process together with the paper, or by mixing the mixture of plastics and paper crushing process, the steps of the humidity controlled the debris mixture wetted the tone and the debris mixture was then compressed molding curing, a step of producing a carbide and plastic-containing solid fuel wastes, comprises a moisture adjusting material to be mixed in the step of the above-mentioned humidity controlled the crushed pieces mixture As the amount of paper as, the amount of water in the crushed piece mixture is such that the amount of water can be a proportion of the amount of water that can generate heat up to a temperature that softens the crushed pieces of plastic during compression molding. Waste carbide and A method for producing a stick-containing solid fuel, and a pulverizer for pulverizing the waste carbide on the downstream side of a carbide extraction line for extracting the carbide from a pyrolysis furnace for pyrolyzing the waste into pyrolysis gas and carbide a humidistat for humidity control the carbide which is ground in the grinder, provided with a, a crusher for crushing a paper supplied from the supply portion of the plastic and paper supplied from the supply portion of the plastic provided, upstream or downstream of the crusher, by supplying a carbide moistened adjusted by the humidistat, the carbon compound is mixed with the plastic and paper, and the humidity controlled the crushed pieces mixture , further comprising a molding machine for compression molding the crushed pieces mixtures, the amount of paper as a moisture adjusting material to be mixed in the step of the above-mentioned humidity controlled the fragments mixture, water content of fragments mixture, compressed When molding And an amount to make the percentage of water content to a temperature to soften the debris sticks can increase the temperature of the molding machine, the apparatus for producing carbide and plastic-containing solid fuel wastes having the configuration.

In the above, humidity controlled the carbide method Ru moisture content 1 0-40% der, and, a humidistat, to humidity control in moisture content 10-40% The ground carbide by a pulverizer The device configuration is assumed.

According to the present invention, the following excellent effects are exhibited.
(1) a step of waste is pulverized carbide obtained by pyrolysis at a pyrolysis furnace, the step of humidifying the milled carbide, a該調wetted the carbides, together with the plastic and paper crushing treated by mixing Luke, or by mixing the mixture of plastics and paper crushing process, the steps of the humidity controlled the debris mixture, the humidity controlled the debris mixture, compression molding and then curing, carbide and a step of producing a plastic-containing solid fuel, comprising a quantity of paper as a moisture adjusting material to be mixed in the step of the above-mentioned humidity controlled the crushed pieces mixtures waste fragments Waste carbonized and plastic-containing solid fuel having a structure in which the moisture content of the mixture is such that the moisture content is such that it can generate heat up to a temperature at which the plastic fragments are softened during compression molding How to make And waste downstream of the carbide extraction line for taking out the carbide from thermally decomposed pyrolytic furnace pyrolysis gas and carbides, and grinder for grinding carbides of the waste, pulverized by the pulverizer A humidity controller for conditioning the generated carbide, and a crusher for crushing the plastic supplied from the plastic supply unit and the paper supplied from the paper supply unit. By supplying the carbide conditioned by the humidity controller to the upstream side or the downstream side, the carbide is mixed with plastic and paper to obtain a crushed fragment mixture, and further, the fragment mixture. The amount of paper used as a moisture adjustment raw material to be mixed in the above-mentioned process for preparing a crushed crushed piece mixture is determined by the amount of water in the crushed piece mixture. Soften And an amount to make the percentage of water content can increase the temperature of the molding machine to time, since the apparatus for producing carbide and plastic-containing solid fuel wastes having a structure, the carbide waste, Since it can be pulverized and humidity-controlled to reduce the particle size and can be mixed with plastic in a state of adhesion, any waste carbide and plastic can be used without requiring a separate binder such as lignin as a secondary material. It is possible to produce waste carbide and plastic-containing solid fuel mixed at a ratio of In addition, the properties of the carbonized waste fuel and plastic-containing solid fuel produced can be made dense and mixed and homogenized as a whole, and the homogeneity of individual solid fuel particles as a product can be improved. Can be increased. Thereby, it becomes possible to improve the combustibility as a fuel and to obtain a high-quality solid fuel that does not cause unevenness in the combustion state when it is burned.
(2) Since the carbides contain moisture, prevent the carbides from scattering in the manufacturing stage and product transport line, reduce the proportion of unmolded carbides remaining in the product, and improve yield. When the compression molding is performed, the carbide is in a state of containing moisture so that there is no risk of ignition even if the temperature rises due to frictional heat or the like during compression molding. It is possible to avoid the phenomenon that the fire type remains in the compression molded product after the compression molding, and more reliably eliminates the possibility that the waste carbide as a product and the plastic-containing solid fuel are ignited. Furthermore, the moisture contained in the conditioned carbide is almost evaporated at the stage where the compression molded product heated by the compression heat at the time of compression molding is cooled, so that a separate drying device or the like is not required. Solid waste fuel and plastic-containing solid fuel can be produced as a dried product.
(3) Further, after pulverizing the waste carbide on the upstream side or the downstream side of the crusher in the facility for producing the mixed fuel (C-RPF) using raw waste carbide, waste plastic and waste paper as raw materials, If it is possible to supply conditioned and conditioned carbides, the present invention can be easily applied to facilities for producing mixed fuels using conventional waste carbides, waste plastics and waste paper as raw materials. It becomes.
(4) together with the humidity controlled the carbide plastic, or, when solely to crushing, so are as adding the required amount of paper, the entire amount of water at the time of compression molding in the compressor It becomes possible to adjust.
( 5 ) Since the moisture-controlled carbide has a moisture content of 10 to 40%, it is possible to more reliably prevent the carbide from being scattered and to perform compression molding in the molding machine more favorably.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 shows an embodiment of a method and an apparatus for producing waste carbide and plastic-containing solid fuel according to the present invention. Waste 1 such as municipal waste is pyrolyzed in a pyrolysis furnace 2 to produce pyrolysis residues. The carbide 3 is produced as follows, and the carbide 3 is pulverized by a pulverizer 4 and then a required amount of water 6 is added by a humidity controller 5 to obtain a predetermined moisture content, for example, 10 to 40%, The moisture content is adjusted to a moisture content of 20 to 30%, and the conditioned carbonized material 3a and waste plastic 7 are supplied to the crusher 9 with waste paper 8 added if necessary, The above raw materials are crushed together in the crusher 9 and mixed together to obtain a crushed mixture 10, and then the crushed mixture 10 is compression-molded and stored in a curative state to produce waste carbides and plastic-containing solid fuel. (C-RPF) 11 is manufactured.

  More specifically, the waste 1 can be indirectly heated by external heat to be thermally decomposed into a pyrolysis gas and a carbide 3 as a pyrolysis residue, and the carbide 3 can be separated from the pyrolysis gas and taken out. The pyrolysis furnace 2 is provided, and the waste (general waste) 1 such as municipal waste and the chlorine-containing plastic 12 such as vinyl chloride are combined with the pyrolysis furnace 2 or individually. A supply unit (not shown) for supplying to is attached. On the downstream side of the carbide take-out line 13 for taking out the carbide 3 from the pyrolysis furnace 2, a carbide storage / supply unit 14 that can store and supply the carbide 3 is provided.

  A pulverizer 4 and a humidity controller 5 are provided in this order on the downstream side of the carbide storage / supply unit 14. Thereby, in the state taken out from the pyrolysis furnace 2, it has various shapes such as flakes and powders having a light specific gravity, and the carbide 3 that cannot be easily mixed by simply adding water, The carbide storage / supply unit 14 supplies the pulverizer 4 to the pulverizer 4 and pulverizes it to form a homogeneous powder, which is then sent to the humidity controller 5. By adding 10 to 40% of water 6 to the powdered carbide 3, the moisture-controlled carbide 3a having a moisture content of 10 to 40% can be generated. Here, the moisture content is set to 10 to 40%. When the moisture content is less than 10%, the carbide 3 is crumpled and has little effect of humidity control such as scattering prevention, and the effect of improving the adhesion to plastic and paper. On the other hand, when the water content exceeds 40%, the carbide 3 becomes sticky and excessively adherent, and it adheres to the downstream equipment, making stable operation difficult, and the compression described later. This is because it is difficult to evaporate water in the molding machine 17.

  A crusher 9 is provided on the downstream side of the humidity controller 5, and on the upstream side (inlet side) of the crusher 9, waste plastic as industrial waste with a clear discharge source or pre-sorting is used as a raw material. Waste plastic supply unit 15 for supplying waste plastic (hereinafter simply referred to as waste plastic) 7 that does not contain chlorine-containing plastic such as waste plastic in general waste, and a raw material for re-humidification described later, A waste paper that is difficult to recycle as an industrial waste whose emission source is clear and a waste paper supply unit 16 for supplying waste paper 8 that has been previously selected from general waste are attached. Accordingly, the waste plastic 7 supplied from the waste plastic supply unit 15 and the carbide 3a conditioned to a moisture content of 10 to 40% sent from the humidity controller 5 can be mixed at an arbitrary ratio, for example, 1: 1. Then, after the required amount of used paper 8 is supplied from the used paper supply unit 16 as necessary, these raw materials are crushed together, and this crushed processing is performed. Accordingly, the waste plastic 7, the conditioned carbide 3 a and the crushed pieces of the used paper 8 can be mixed (kneaded).

  Further, at the downstream position of the crusher 9, as a molding machine, for example, a compression (extrusion) molding machine that performs the same compression molding as the compression / granulation apparatus e including the ring die g shown in FIG. 17, the waste plastic 7, the conditioned carbide 3 a and the waste paper 8 are crushed and mixed at the same time by the crusher 9, and a crushed piece mixture 10 is compressed through a die (not shown) while being compressed. Extrude to form. For this purpose, the compression molding machine 17 causes the crushed piece mixture 10 to generate heat by the generated frictional heat, and the crushed pieces of the waste plastic 7 in the crushed piece mixture 10 are softened. The crushed pieces of plastic 7 are fused with the conditioned crushed carbide 3a and the crushed pieces of waste paper 8 contained in the crushed piece mixture 10 so that an integrally molded compression molded article 11a can be obtained. It is.

  On the downstream side of the compression molding machine 17, a curing storage zone 18 is provided, and the compression molding product 11 a that is heated by frictional heat generated during compression molding of the fragment mixture 10 in the compression molding machine 17, The molded product 11a itself is naturally dried and cured by the heat so that the waste carbide and plastic-containing solid fuel 11 can be obtained.

  In the case of producing the waste carbide and plastic-containing solid fuel 11 using the waste carbide and plastic-containing solid fuel production apparatus of the present invention having the above configuration, first, the waste 1 and the chlorine-containing plastic 12 are heated. It is supplied to the cracking furnace 2 and thermally decomposed, and the carbide 3 generated by this thermal decomposition is temporarily stored in the carbide storage / supply unit 14.

  Next, after the carbide 3 supplied from the carbide storage / supply unit 14 is pulverized by the pulverizer 4, the moisture content is adjusted by the humidity controller 5 so that the moisture content becomes 10 to 40%. The carbide 3a and the waste plastic 7 supplied from the waste plastic supply unit 15 are supplied to the crusher 9 at a required mixing ratio. Further, the amount of water derived from the above-conditioned moisture-comprising carbide 3a is larger than the total amount of the crushed and mixed in the crusher 9, and friction due to sufficient compression at the time of compression molding by the compression molding machine 17 in the next step. When it becomes difficult to generate heat, the waste paper supply unit 16 is used as a raw material for re-humidification for the purpose of moisture adjustment in order to reduce the ratio of the moisture content to the total amount to be crushed and mixed. After the required amount of waste paper 8 is added, it is crushed and mixed.

  As a result, the moisture-controlled carbide 3a, waste plastic 7 and waste paper 8 are crushed to a required size, and at the same time, the crushed pieces are mixed to form a crushed piece mixture 10. At this time, since the humidity-adjusted carbide 3a has adhesion due to being in a humidity-controlled state, a binder is required by adhering to the waste plastic 7 and waste paper 8. The pieces can be put together. In addition, since the conditioned carbide 3a is pulverized in advance and has a fine particle size, it can be dispersed well. For this reason, even if a specific gravity difference or a size difference is generated among the crushed pieces of the conditioned carbide 3a, the waste plastic 7 and the used paper 8, the crushed pieces of the raw materials are caused by the specific gravity difference or the size difference. Since the possibility that the distribution is biased can be prevented, the fragment mixture 10 to be generated can be mixed and homogenized as a whole.

  Therefore, after that, when the crushing piece mixture 10 obtained from the crusher 9 is compression-molded by the compression molding machine 17 to form the compression-molded product 11a, the obtained compression-molded product 11a is the same as the crushing piece mixture 10 described above. Furthermore, the crushed pieces of the conditioned carbide 3a, the waste plastic 7 and the waste paper 8 are uniformly dispersed throughout. Furthermore, since the moisture-controlled carbide 3a is pulverized in advance and has a fine particle size, the fusion property with the waste plastic 7 can be enhanced, and a compression-molded product 11a having a stable property can be formed. The carbide 3 is a conditioned carbide 3a, that is, compression molding is performed in a conditioned and adherent state, so that the unmolded carbide in the compression molded product 11a after compression molding. 3 can be eliminated, and even if heat is generated due to frictional heat generated during compression molding, the possibility that the carbide 3 is ignited or a fire type remains in the formed compression molded article 11a can be eliminated.

  Thereafter, the compression-molded product 11a is dried and cured in the curing storage zone 18 using the heat of the compression-molded product 11a itself that has been heated by the heat acting during the compression molding. As a result, the dried product, that is, the waste carbide and the plastic-containing solid fuel 11 having a required shape corresponding to the shape of the compression molded product 11a are manufactured.

  Thus, if it is set as the manufacturing method and apparatus of the carbide | carbonized_material of a waste of this invention, and a plastic containing solid fuel, without requiring a binder like lignin as an auxiliary material separately, the waste 1 and the chlorine containing plastic 12 The waste carbide and the plastic-containing solid fuel 11 obtained by mixing the carbide 3 and the waste plastic 7 as main raw materials and appropriately mixing the waste paper 8 at a required ratio can be manufactured. Therefore, as an alternative to the waste paper d used as the raw material of the solid fuel n described in Patent Document 1, the carbide 3 is mixed with the waste plastic 7 at an arbitrary ratio, and a more stable property as C-RPF is obtained. Waste carbonized material and plastic-containing solid fuel 11 can be produced.

  In addition, the carbide 3 used as a raw material is mixed with waste plastic 7 and waste paper 8 in a state where the particle size is reduced and the moisture is adjusted to produce adhesiveness. The properties of the carbide and the plastic-containing solid fuel 11 can be made dense and mixed and homogenized as a whole, and the homogeneity of the individual particles of the waste carbide and the plastic-containing solid fuel as a product Thus, it is possible to improve the combustibility as a fuel and to obtain a high-quality solid fuel that does not cause unevenness in the combustion state during combustion.

  Furthermore, when the carbide 3 is put into the crusher 9, it is in a state of containing 10 to 40% of water, so that the carbide 3 is surrounded by the crushing and mixing process in the crusher 9. The possibility of splashing can be eliminated. Similarly, when the crushed piece mixture 10 is compression-molded by the compression molding machine 17, the carbide 3 is in a conditioned state, and there is no possibility that the carbide is scattered around. Therefore, it is possible to prevent the carbide 3 from being scattered in the manufacturing stage or the product conveyance line.

  Accordingly, it is possible to reduce the proportion of the unmolded carbide 3 remaining in the product and further improve the yield. Further, since the carbide 3 contains moisture at the time of compression molding, there is no risk of ignition even if the temperature rises due to frictional heat or the like during compression molding, and the temperature rises locally. It is possible to avoid a phenomenon in which a fire type remains in the compression molded product 11a, and to reliably eliminate the possibility that the waste carbide as a product and the plastic-containing solid fuel 11 are ignited during curing.

  The moisture contained in the conditioned carbide 3a is almost evaporated at the stage of cooling the compression molded product 11a heated by the compression heat at the time of compression molding. The carbonized waste and plastic-containing solid fuel 11 can be produced as a dried product.

  Furthermore, conventionally, a facility for producing a mixed fuel (C-RPF) using waste carbide, waste plastic and waste paper as raw materials also includes waste plastic supplied from the waste plastic supply section, and waste paper supplied from the waste paper supply section. And a crusher for crushing and mixing at the same time, and a compression molding machine for compressing and molding a mixture of waste carbide, waste plastic and waste paper obtained by the crusher A crusher 4 and a humidity controller 5 for crushing the carbide 3 of the waste 1 are provided on the upstream side of the crusher, and the carbide 3a conditioned by the humidity controller 5 is supplied to the crusher. If it is the structure which can be supplied to this, it will become possible to apply this invention easily to the facility which manufactures mixed fuel (C-RPF) from the conventional waste carbide, waste plastic, and waste paper.

  As described above, the waste paper 8 is a rehumidification raw material that is added to adjust the amount of water in the whole shredded mixture 10 when the shredded mixture 10 is compression-molded. The amount of water in the crushed piece mixture 10 formed by crushing and mixing only the carbonized material 3a and the waste plastic 7 is a water amount suitable for compression molding by the compression molding machine 17, When the temperature of the compression molding machine can be sufficiently increased to a temperature at which the crushed pieces of the waste plastic 7 are softened during the compression molding, the waste paper 8 may not be added.

  Moreover, in the said embodiment, although demonstrated as what compresses by the compression molding machine 17 of the type which comprises a ring die, it shape | molds while compressing and extruding from the required die | dye to the fragment mixture 10. The temperature of the mixture 10 is increased to a temperature at which the mixture 10 can be integrated by softening the fragments of waste plastic 7 and fusing them with the fragments of carbide 3 and waste paper 8 by frictional heat generated during molding. If possible, various types of molding machines generally used for compression molding may be employed. In this case, depending on the level of the temperature that can be applied at the time of compression molding, because the temperature that can be applied when compressing and molding the crushed piece mixture 10 is different depending on the type of the molding machine to be adopted, What is necessary is just to adjust suitably the moisture content of the carbide | carbonized_material 3a conditioned by increasing / decreasing the quantity of the water contained in the carbide | carbonized_material 3 with the humidity controller 5.

  Next, FIG. 2 shows another embodiment of the present invention. In the same configuration as shown in FIG. 1, the carbide 3 of the waste 1 is pulverized by the pulverizer 4, and then the humidity controller 5 is used. Instead of the configuration in which the conditioned carbide 3a obtained by adding water 6 to the crusher 9 for crushing the waste plastic 7 and the waste paper 8 is supplied from the humidity controller 5 above. The carbonized material 3a thus conditioned is mixed with the waste plastic 7 obtained from the crusher 9 and the crushed piece mixture 10a of the used paper 8.

  In addition, as a method of adjusting the humidity of the carbide 3, it is common to add water by spraying or the like. However, when a process for washing to remove chlorine content is added, a dehydrator or a dryer is added. May be used to reduce the moisture content to the required moisture content. Furthermore, in order to further enhance the moldability, it is naturally possible to employ a method of molding by adding additives such as lignin as in the prior art.

  Other configurations are the same as those shown in FIG. 1, and the same components are denoted by the same reference numerals.

  Also according to this embodiment, the same effect as that of the above embodiment can be obtained.

  Also in the present embodiment, it is obtained from the humidity controller 5 on the downstream side of the crusher in the facility for producing the mixed fuel (C-RPF) using the conventional waste carbide, waste plastic and waste paper as raw materials. If it is set as the structure which can supply the moisture-controlled carbide | carbonized_material 3a, it can be easily applied to the facility which manufactures mixed fuel (C-RPF) from the carbide | carbonized_material of a conventional waste, waste plastic, and waste paper as a raw material. .

  Further, in the present embodiment, as in the above embodiment, when the waste paper 8 is compression-molded into the crushed piece mixture 10a, it is determined whether or not to add in consideration of the moisture content of the crushed piece mixture 10a as a whole. It may be determined. In addition, instead of the waste paper 8, it is also possible to use biomass containing fibers such as grass and wood dried together with the waste paper 8.

  In addition, this invention is not limited only to the said embodiment, For example, in the curing storage zone 18, when there exists another surplus air supply source, ventilation etc. are performed and a compression molded product is performed. You may make it cool and dry 11a more actively. The pyrolysis furnace 2 may be any type of pyrolysis furnace 2 as long as it can separate and recover the carbide 3 generated by pyrolyzing the waste 1 and the chlorine-containing plastic 12 from the pyrolysis gas. As a raw material for pyrolyzing the pyrolysis furnace 2 to generate the carbide 3, only the waste 1 may be used without using the chlorine-containing plastic 12. In addition, it goes without saying that various changes can be made without departing from the scope of the present invention.
