Description

  The present invention relates to a recycling apparatus that heats and processes a raw material, for example, and particularly relates to a recycling apparatus that acquires rare metal, oil, or both from a charged raw material.

  Conventionally, waste after use is discarded after being reduced in volume, etc., or separated and reused. As a method of reusing, for example, a method of processing an electronic component-mounted printed wiring board in which an electronic component-mounted printed wiring board is subjected to low-temperature carbonization to carbonize a combustible portion, and cooled and crushed has been proposed (see Patent Document 1). ). In this processing method, the shielding door is opened, the processed material A is conveyed from the preheating tank to the heating tank, and the shielding door is closed and heated in the heating tank.

  However, this method takes time to process the raw materials. That is, in this method, when the raw material is moved from the preheating tank to the heating tank and from the heating tank to the cooling tank, the openable / closable shielding door must be opened. Moreover, when the open / close type shielding door is opened, heat exchange is performed between the preheating tank and the heating tank, and between the heating tank and the cooling tank, the temperature of the heating tank is lowered, and the temperature of the cooling tank is raised. Therefore, the heating tank needs to be reheated, and the cooling tank needs to be recooled. For this reason, processing time became long.

JP 2001-81519 A

  An object of this invention is to provide the recycling apparatus which can process and recycle a raw material in a short time in view of the problem mentioned above.

  The present invention includes a charging permission section that allows charging of raw materials, a plurality of heating tanks that heat the raw materials, and a transport unit that transports the raw materials and passes them through all the heating tanks. , Arranged in order, and the conveying means is a recycling apparatus configured to convey the raw materials in the arrangement order.

  According to the present invention, it is possible to provide a recycling apparatus capable of processing and recycling a raw material in a short time.

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is an explanatory diagram viewed from the side showing the configuration of the recycling apparatus 1, and FIG. 2 is a partially enlarged perspective view showing a part of the configuration of the recycling apparatus 1.

  The recycling apparatus 1 includes a raw material supply unit 10, a volume reduction tank 20, a melting tank 30, a thermal decomposition tank 40, a cooling tank 50, and a raw material supply unit 10, in this order, from the target D 1 (raw material). It is mainly comprised by the belt conveyor 70 which conveys. Further, the recycling apparatus 1 includes a chlorine removing device 2 for treating vaporized substances (light oil, heavy oil A, etc.) discharged from the volume reduction tank 20, the melting tank 30, and the thermal decomposition tank 40, a cooling device 3, oil water A separation device 4 and an oil tank 5 are provided.

  The raw material supply unit 10 supplies various raw materials input from the input port 11 to the volume reduction tank 20 from the supply port 12 as the object D1. The wall 13 opposite to the supply port 12 is hermetically sealed and blocked from the outside. Further, the raw material supply unit 10 is formed in a funnel shape whose width is narrowed from the upper charging port 11 toward the lower supply port 12. For this reason, when the raw material as the object D1 is input from the input port 11, it is possible to prevent the gas from flowing backward from the supply port 12 of the raw material supply unit 10 to the input port 11 due to this raw material.

  The volume reduction tank 20 has an inlet side communicating with the supply port 12 of the raw material supply unit 10, and an openable partition plate 25 is inclined on the outlet side. The upper end of the openable / closable partition plate 25 is supported by the rotation connecting portion 24, and is rotated as indicated by an arrow in the figure by the rotational drive of the rotation connecting portion 24. Thus, the state is switched between an open state in which the lower end side communication part 27 allows the object D2 to pass and a closed state in which the communication part 27 is closed and completely sealed. A chain belt 71 of a belt conveyor 70 is disposed below the volume reduction tank 20.

  In addition, a discharge hole 21 for discharging the vaporized material is provided in the upper part of the volume reduction tank 20. The vaporized material (mainly light oil) that has come out of the discharge hole is supplied to the chlorine removing device 2. Further, in the volume reducing tank 20, there is provided a heating steam jetting section 23 for jetting the heating steam obliquely downward from above along an openable / closable partition plate 25 arranged in an inclined manner.

  The heating steam ejection part 23 ejects the heating steam vigorously and reaches the chain belt 71. Thereby, the jetted heated steam becomes an air curtain of the communication portion 27 that connects the volume reduction tank 20 and the melting tank 30, and heat exchange between the volume reduction tank 20 and the melting tank 30 can be prevented. In particular, since the air curtain is formed on the low-temperature volume reduction tank 20 side, it is possible to reliably prevent the high-temperature atmosphere of the melting tank 30 from flowing out to the volume reduction tank 20 side.

  The inside of the volume reduction tank 20 is heated to about 150 ° C. to 200 ° C. by the heating steam supplied from the heating steam ejection unit 23. Accordingly, the light oil component contained in the object D2 is vaporized, and the light oil can be extracted at the subsequent stage of the discharge hole 21. Moreover, this volume reduction tank 20 can reduce the volume of the target object D2 by heating the target object D2.

  The melting tank 30 communicates with the volume-reducing tank 20 through a communication part 27 having an upper and lower height of about 6 cm to 10 cm, and an openable / closable partition plate 35 is inclined on the outlet side. The upper end of the open / close partition plate 35 is supported by the rotation connecting portion 34, and is rotated as indicated by the arrow in the figure by the rotational drive of the rotation connecting portion 34. Thus, the state is switched between an open state in which the lower end side communication portion 37 allows the object D3 to pass and a closed state in which the communication portion 37 is closed and completely sealed. A chain belt 71 of a belt conveyor 70 is disposed below the melting tank 30. In addition, a discharge hole 31 for discharging the vaporized material is provided in the upper part of the melting tank 30. The vaporized substance (mainly A heavy oil) that has come out of the discharge hole is supplied to the chlorine removing device 2. Further, in the melting tank 30, there is provided a heating steam ejection portion 33 for ejecting heating steam from the upper side to the oblique lower side along the opening / closing partition plate 35 that is inclined. The heating steam ejection part 33 ejects the heating steam with force to reach the chain belt 71. Thereby, the jetted heating steam becomes an air curtain of the communication part 37 that connects the melting tank 30 and the thermal decomposition tank 40, and it is possible to prevent temperature exchange between the melting tank 30 and the thermal decomposition tank 40. In particular, since the air curtain is formed on the melting tank 30 side having a low temperature, it is possible to reliably prevent the high temperature atmosphere of the thermal decomposition tank 40 from flowing out to the melting tank 30 side.

  The inside of the melting tank 30 is heated to about 300 ° C. to 350 ° C. by the heating steam supplied from the heating steam ejection unit 33. Therefore, the A heavy oil component contained in the object D3 is vaporized, and the A heavy oil can be extracted at the subsequent stage of the discharge hole 31. In addition, the melting tank 30 can partially liquefy the object D3 by heating the object D3. The liquefied liquefied material passes through the through hole 72 of the chain belt 71 and is recovered from the lower liquid discharge portion 81 to the melt recovery portion 80. By collecting this liquefied material (for example, plastic component) as a liquefied material instead of completely vaporizing it, the time required for processing in the melting tank 30 can be remarkably shortened. That is, conventionally, when heated at about 300 ° C. to 350 ° C., it takes a very long time until the liquefied liquefied product simmers in the lower part and the liquefied product becomes a gas. There was a problem that the object could not be moved. However, by recovering the liquefied material as it is, it is not necessary to spend time until it is vaporized, and the time for processing in the melting tank 30 can be greatly shortened. The recovered liquefied product is preferably treated by an appropriate method such as vaporizing in a separate process. In this case, since the liquefied material does not contain a non-melting substance such as a rare metal, the processing apparatus can be simplified.

  The pyrolysis tank 40 communicates with the melting tank 30 at a communication portion 37 having an entrance height of about 6 cm to 10 cm in the vertical direction, and an open / close partition plate 45 is inclined on the outlet side. The upper and lower ends of the open / close partition plate 45 are supported by the rotation connecting portion 44, and are rotated as indicated by the arrows in the drawing by the rotational drive of the rotation connecting portion 44. Accordingly, the state is switched between an open state in which the lower end side communication portion 47 allows the object D4 to pass and a closed state in which the communication portion 47 is closed and completely sealed. A chain belt 71 of the belt conveyor 70 is disposed below the pyrolysis tank 40. In addition, a discharge hole 41 for discharging the vaporized material is provided in the upper part of the thermal decomposition tank 40. The vaporized substance (mainly A heavy oil) that has come out of the discharge hole is supplied to the chlorine removing device 2. Further, in the pyrolysis tank 40, a heating steam ejection part 43 for ejecting the heating steam obliquely downward from above is provided. The heating steam ejection part 43 ejects the heating steam vigorously and reaches the chain belt 71. Thereby, the sprayed heating steam becomes an air curtain of the communication part 47 that connects the thermal decomposition tank 40 and the cooling tank 50, and it is possible to prevent temperature exchange between the thermal decomposition tank 40 and the cooling tank 50.

  The inside of the pyrolysis tank 40 is heated to about 450 ° C. to 500 ° C. by the heating steam supplied from the heating steam ejection unit 43. Therefore, the A heavy oil component contained in the object D4 is vaporized, and the A heavy oil can be extracted at the subsequent stage of the discharge hole 41. Moreover, since this thermal decomposition tank 40 heats the target object D4 at very high temperature, the carbide | carbonized_material which carbonized the target object D4 and the rare metals, such as copper, iron, and aluminum which were contained in the target object D4, are made into a residue. It can be conveyed to the cooling tank 50 in the subsequent stage by the chain belt 71. Here, the volume reduction tank 20, the melting tank 30, and the thermal decomposition tank 40 are arrange | positioned in order from the thing with a low temperature to a high thing.

  The cooling tank 50 communicates with the pyrolysis tank 40 at a communication part 47 having an entrance height of about 6 cm to 10 cm on the entrance side, and cools the object D5 conveyed from the communication part 47. The cooling tank 50 is a tank that cools to 100 ° C. or less, and collects the cooled object D5 in the collecting unit 51. Thereby, rare metals and carbon can be safely recovered at a low temperature.

  The belt conveyor 70 rotates a chain belt 71 that has a hole and allows liquid to pass therethrough, and conveys the object D (D1 to D5) on the chain belt 71. The conveyance of the object D by the chain belt 71 is continuously conveyed without stopping, or is stopped under certain conditions (for example, a certain period of time) and intermittently conveyed. It may be appropriately controlled by a control device (not shown) according to whether it is a rare metal or A heavy oil.

  As shown in FIG. 2, a steam heating unit 60 for heating steam is provided on the side surfaces of the volume reduction tank 20, the melting tank 30, and the pyrolysis tank 40 described above in contact with or close to the wall surface. . In the steam heating unit 60, a heater 61 is disposed on the outer periphery of a pipe 62 that transports steam. Thereby, a vapor | steam can be heated to required temperature and this heating vapor | steam can be supplied in the volume reduction tank 20, the melting tank 30, and the thermal decomposition tank 40 from the heating vapor | steam ejection parts 23,33,43, respectively. Since the steam heating unit 60 is in contact with or close to the side surfaces of the volume reduction tank 20, the melting tank 30, and the thermal decomposition tank 40, the preheating of the heater 61 for heating the steam is reduced in volume reduction tank 20, melting tank 30, And is transmitted to the pyrolysis tank 40. Therefore, the volume reduction tank 20, the melting tank 30, and the thermal decomposition tank 40 can be heated efficiently.

The chlorine removing device 2 shown in FIG. 1 performs a dehalogenation step for removing chlorine from the inflowing vaporized material, and sends the vaporized vapor removed to the cooling device 3.
The cooling device 3 cools and liquefies the inflowing vaporized material, and sends the liquefied material to the oil / water separation device 4.
The oil / water separator 4 separates the liquefied material that has flowed into the oil / water, and sends the oil (A heavy oil, light oil, etc.) to the oil tank 5.
The oil tank 5 stores the oil component that has flowed in.

FIG. 3 is a flowchart for explaining a process in which the object D input to the recycling apparatus 1 is processed.
First, the object D to be processed is put into the raw material supply unit 10 (step S1). The object D may be a single article if material recycling is performed. In the case of waste disposal, the object D may be a mixture of various articles such as plastic, metal products, a mixture of metal and plastic, textile products, products made of thermoplastic resin, foodstuffs, and the like. In this mixing, it is only necessary to put in various wastes, and it is not necessary to perform a special treatment such as stirring.

  The volume is reduced in a volume reduction process performed by the volume reduction tank 20 (step S2). The volume reduction tank 20 implements this volume reduction step at an ambient temperature of 150 ° C. to 200 ° C. filled with heated steam. At this time, the volume reduction tank 20 sends the vaporized material that has become a gas to the chlorine removing device 2 and sends the solid to the melting tank 30.

  The solid that has passed through the volume reduction process is melted in the melting process performed by the melting tank 30 (step S3). The melting tank 30 carries out this melting step at an ambient temperature of 300 ° C. to 350 ° C. filled with heated steam. At this time, the melting tank 30 sends the vaporized material that has become a gas to the chlorine removing device 2, and sends the liquefied material that has been melted into a liquid to the melt collecting unit 80.

  Here, if the object D to be processed is a fiber such as 30% cotton and 70% polyester, the polyester component becomes liquid and is sent to the melt recovery unit 80 and can be reused as pellets. It can be reused as carbide for water purification. In addition, when the object D to be processed is a product containing a plastic component, or waste oil or waste, the oil is evaporated and extracted as a vaporized substance, and the carbide or metal is solid as a residue. Remain.

The solid that has passed through the melting step is pyrolyzed in a pyrolysis step performed by the pyrolysis tank 40 (step S4). The pyrolysis tank 40 performs this pyrolysis step at an ambient temperature of 450 ° C. to 500 ° C. filled with heated steam. At this time, the pyrolysis tank 40 sends the vaporized material (mainly A heavy oil component or the like) that has become a gas to the chlorine removing device 2. In this pyrolysis, solid carbide and metal remain as a residue.
Here, if the object D to be treated is, for example, a fiber such as 30% cotton and 70% polyester, the carbon component remains because the polyester component has already been removed in the melting step. In addition, when the object D to be processed is a product containing a plastic component, or waste oil or waste, the oil is evaporated and extracted as a vaporized substance, and the carbide or metal is solid as a residue. Remain.

  The solid that has passed through the pyrolysis process is cooled in a cooling process performed by the cooling bath 50 (step S5). The cooling bath 50 performs this cooling process at an ambient temperature of 100 ° C. or less.

  And the residue which was cooled to 100 degrees C or less by the cooling process is collect | recovered by a collection process (step S6). In this recovery step, for example, in the case of rapid cooling in the cooling tank 50, the cooled residue may be continuously discharged as it is. When it takes time to cool in the cooling tank 50, it is preferable to complete the cooling by a certain amount and collect the batch by a certain amount.

  The vaporized substance sent to the dehalogenation process is chlorine-removed (dehalogenated) by the chlorine removal device 2 (step S7). The vaporized product from which chlorine has been removed is sent to the cooling step.

  In the cooling process, the vaporized material is cooled by the cooling device 3 and returns to the liquid (step S8). The liquid may be light oil or heavy oil A depending on the component of the object D or the vaporized material sent out from the volume reduction tank 20, the melting tank 30, or the thermal decomposition tank 40. This oil component is sent to the recovery process and recovered (step S9). In this collection, the oil / water separation device 4 may separate the oil and water, or may collect the oil as it is without separation.

The liquefied material sent from the melting process to the cooling process is cooled by the cooling process and returned to a solid (step S10). This cooling step is preferably performed in a cooling tank (not shown).
And the solid which passed the cooling process is collect | recovered by the melt collection part 80 at a collection process (step S11).

  With the above configuration and operation, the thrown object D can be continuously processed in a short time. When the object D is a waste product in which various articles are mixed, it is possible to obtain vaporized oil, dissolved pellet components, solidified carbide and metal. This waste includes thermoplastic resins, FRP (Fiber Reinforced Plastics), waste plastics, waste oil, electric wires, waste tires, expired convenience store lunches (lunch items containing food in plastic containers sold at convenience stores, etc.) Construction waste (wood scrap, metal scrap, electric wire scrap, glass, ceramics, etc.), uniforms, and the like.

  In addition, even when a product containing FRP (Fiber Reinforced Plastics), which is generally difficult to break, is introduced as the object D, the oil can be evaporated and embrittled, and a compact breakage treatment can be performed.

  Moreover, since the communication parts 27, 37, and 47 are gaps of 6 cm to 10 cm which are very low as compared with the respective heights of the volume reduction tank 20, the melting tank 30 and the thermal decomposition tank 40, the volume reduction tank even when left open. 20, heat exchange between the melting tank 30 and the thermal decomposition tank 40 can be prevented.

  Further, since the heated steam is ejected vigorously from the heated steam ejection portions 23, 33, 43 and reaches the chain belt 71, the air curtain of the communication portions 27, 37, 47 can be formed by the ejected heated steam. Thereby, it is possible to reliably prevent temperature exchange between the volume reduction tank 20 and the melting tank 30, between the melting tank 30 and the thermal decomposition tank 40, and between the thermal decomposition tank 40 and the cooling tank 50.

  In an emergency, the opening / closing partition plates 25, 35, 45 can be closed by the driving force of the rotation connecting portions 24, 34, 44, so that the volume reduction tank 20, the melting tank 30 and the pyrolysis tank 40 are completely separated. It is possible to increase the safety by preventing the propagation of trouble.

  In addition, the recycling apparatus 1 extracts pellets from the melting tank 30, extracts light oil from the vaporized material discharged from the discharge holes 21, and extracts heavy fuel oil A from the vaporized materials discharged from the discharge holes 31 and 41. For example, carbide or rare metal can be extracted from the portion 51. Therefore, the recycling apparatus 1 can be used for material recycling.

  In addition, although the volume reduction tank 20, the melting tank 30, and the thermal decomposition tank 40 were arranged in the horizontal direction, you may arrange in not only this but inclination arrangement | positioning or vertical arrangement | positioning. In this case, it is preferable to arrange in order so that the volume reduction tank 20 is the lowest and the pyrolysis tank 40 is the highest position. Thereby, the principle that high temperature gathers up can be used effectively, and it can be realized easily to make pyrolysis tank 40 the highest temperature.

  Further, the recycling apparatus 1 may be configured like the recycling apparatus 1a shown in FIG. In this embodiment, a belt conveyor 70a that conveys a waste object from the raw material supply unit 10 obliquely upward is provided, and a volume reduction tank 20 that is heated to about 160 ° C. is provided at the lower part of the conveyance end of the belt conveyor 70a. A belt conveyor 70b is provided in the volume-reducing tank 20, and the tip of the belt conveyor 70c of the melting tank 30 that is heated to about 300 ° C. is disposed below the conveyance end portion of the belt conveyor 70b. An openable / closable partition plate 25 is provided at a connection portion between the volume reducing tank 20 and the melting tank 30.

  A screw feeder 83 is provided below the melting tank 30 to convey the melted object. The screw feeder 83 executes a cutting process for cutting the melted object. The object conveyed by the screw feeder 83 is cooled in a cooling tank 84 that performs a cooling process. The cooled object is recovered from the cooling tank 84 to the recovery unit 85 by the belt conveyor 70f.

  A thermal decomposition tank 40 that is heated to about 450 ° C. is provided at the subsequent stage of the melting tank 30, and an openable / closable partition plate 35 is provided at the connecting portion. A belt conveyor 70d is provided in the lower part of the pyrolysis tank 40 and conveys the object.

At the subsequent stage of the pyrolysis tank 40, another pyrolysis tank 40 that is heated to about 500 ° C. is connected, and an openable and closable partition plate 45 is provided at the connecting portion between the two. A belt conveyor 70e is provided in the lower part of the pyrolysis tank 40 and conveys an object.
A cooling tank 50 is provided below the end of conveyance of the belt conveyor 70e.

  The volume reduction tank 20, the melting tank 30, and the thermal decomposition tank 40 are respectively provided with heating steam ejection portions 23, 33, and 43 that eject heating steam. Heated steam is supplied to the heated steam ejection parts 23, 33, and 43 from a heated steam generator 64 heated by the boiler 63.

And while the target object moves from the raw material supply unit 10 to the cooling tank 50 through the volume reduction tank 20, the melting tank 30, and the thermal decomposition tank 40, the vaporized material of the input raw material does not leak to the outside. The outer wall A is completely covered.
Since other configurations are the same as those of the first embodiment, the same reference numerals are given to the same elements, and detailed description thereof is omitted.
With the above configuration, the same effects as those of the first embodiment can be obtained.

  Moreover, in the Example mentioned above, although each temperature of the volume reduction tank 20, the melting tank 30, and the thermal decomposition tank 40 was made into different temperature, you may make all the same temperature. In this case, as in the embodiment shown in FIG. 4, a belt conveyor 70 may be provided independently for each tank, and the conveying speeds of the belt conveyors 70a, 70b, 70c, 70d of each tank may be varied. Specifically, in the volume-reducing tank 20 that requires less heat transfer, the belt conveyor 70b may be configured to be conveyed earlier than other belt conveyors 70c and the like. Thereby, it can implement | achieve that it does not liquefy, reducing volume. Further, when it is desired to increase the temperature of the object D, the object D can be heated to a sufficient temperature and liquefied by, for example, conveying the object D more slowly than the other belt conveyors 70c or the like by the belt conveyor 70d. In this manner, volume reduction, liquid extraction, and gasification of oil can be realized in each tank by changing the conveying speed of the belt conveyor (70b, 70c, 70d) of each tank (20, 30, 40). it can.

  Moreover, in the Example mentioned above, although it was set as the structure which heats the inside of the melting tank 30 to about 300 degreeC-350 degreeC, it is good to adjust according to the substance to collect | recover not only at this temperature but the melt collection part 80. For example, if you want to acquire foamed styrene, about 200 ° C to 300 ° C, if you want to acquire acrylic (or PPC, polyimide, etc.), about 300 ° C to 600 ° C, if you want to acquire zinc, 800 ° C The inside of the melting tank 30 may be heated to the extent. By doing in this way, according to the target object D inputted as a raw material, an acquirable substance (foamed polystyrene, acrylic, zinc, etc.) can be melted and liquefied at an appropriate temperature and efficiently obtained. . Moreover, even when zinc and iron are mixed, zinc can be recovered by the melt recovery unit 80, and iron remaining as a residue can be recovered from the cooling tank 50 and material recycled. In addition, when heating the inside of the melting tank 30 to about 800 degreeC and taking out zinc, it is good to make the thermal decomposition tank 40 into about 800 to 1000 degreeC.

  Moreover, you may adjust the temperature of each tank (20,30,40) according to the temperature of the oil component to vaporize and to acquire. Thereby, it becomes possible to separate and collect various oil components such as light oil, heavy oil A and heavy oil C.

  Further, the recycling apparatuses 1 and 1a can reduce the volume of waste, extract oil components, and perform material recycling even when waste is input. Therefore, the recycling apparatuses 1 and 1a can be used as a waste treatment apparatus.
