Artificial marble has attracted a great deal of attention as a material for construction due to recent trends in the upgrading and comfort of buildings. Artificial marble refers to a synthetic compound that combines natural ores or minerals with resin components or cement, and incorporates various pigments and additives to provide the natural marble texture.

At present, organic artificial marble is mixed with an acrylic resin (organic substance) called Methyl Methacrylate (MMA) and an inorganic filler. In this artificial marble, composition ratio of each material is methacrylic acid methyl Is 30 to 45% by weight, the inorganic filler is 45 to 65% by weight, and the remainder is made of an additive. As the inorganic filler, most of the aluminum hydroxide is used, which is good in the strength and wear resistance of artificial marble.

Artificial marble is processed to the required size after manufacturing and is widely used as a sink, a counter top, a kitchen top plate, a counter top plate of a public building, a table and an interior material of a garnet, and a lot of dust and scrap are generated in the process of manufacturing these products . In addition to the rapid increase in production volume due to the various advantages of artificial marble, the amount of dust and scrap emitted during the processing process is also greatly increasing. Especially, the amount of crude marble discarded in the remodeling or reconstruction process after use is considerable It is.

On the other hand, acrylic resin products used for making decorative articles such as signboards also undergo work such as cutting and processing during the production of articles, so that a considerable amount of dust and scrap are generated.

The artificial marble dust powder produced in the process of producing specific products with artificial marble occupies an enormous proportion, which accounts for 10% of the total artificial marble production, and the dust and powder of acrylic resin generated during the manufacture of signs and interior products Scrap also occurs very much like artificial marble.

These waste marble dust, scrap and acrylic resin powders and scrap were traditionally handed over to the waste disposal company for disposal costs, and waste disposal companies were disposed of in landfills or incinerated. This waste disposal method is a waste of artificial marble and acrylic resin, which are valuable resources, and it was necessary to develop a technique for recycling raw materials by reusing them.

The waste marble is heated in a reactor 802 to generate a gas containing methyl methacrylate, and then the gas is cooled to obtain methyl methacrylate FIG. The waste marble is crushed and placed in a storage hopper 801 and then supplied to the reactor 802 to be heated and stirred while being heated by the heat of the electric heater 802b to pyrolysis the waste marble. Due to the pyrolysis of the marble, it is decomposed again into polymethyl methacrylate, water and aluminum oxide (alumina). 2, the gaseous methyl methacrylate and water are discharged from the reactor 802 and transferred to the condenser 803. After being converted into the liquid state by being condensed by the cooling water supplied from the cooling water supply device 804, 805). In the separator 805, water is located below the methyl methacrylate in the oil component, so that the water is withdrawn from the bottom of the separator 805, and the methyl methacrylate in the upper layer is transferred to the purity adjuster 808. The purity of the methyl methacrylate introduced into the purity adjuster 808 is adjusted by the additives to be added, and then the foreign substances are collected through the filter 809 in a filtered state.

In FIG. 2, reference numeral 806 denotes a vacuum pump for applying a vacuum to absorb moisture remaining in the reactor 802 as much as possible. Reference numeral 807 denotes a water / odor eliminator for removing moisture and odor remaining in the separator 805. to be.

Korean Patent No. 1022512 discloses a process for recovering methyl methacrylate as well as a process for recovering aluminum oxide by calcining aluminum oxide by condensing the gas obtained after pyrolysis process of the crude marble .

However, both the prior art of FIG. 1 and the prior art of Japanese Patent No. 1022512 are operated in a batch type reactor, and the recovery rate of methyl methacrylate is not so high.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout.

FIG. 2 is a block diagram of a hybrid type recycling system for waste marble, acrylic, and biomass using a fluidized-bed rapid thermal decomposition technique according to the present invention.

Referring to FIG. 2, the apparatus for recycling hybrid type marine marble, acrylic resin, and biomass using the fluidized-bed rapid pyrolysis technique of the present invention comprises a crushing material 2 of a crude marble or a first supply A third feed hopper 12 for storing a crushing product of biomass resources such as a hopper 11, a waste acrylic resin waste 3 or a second feed hopper 12 for storing dust powder, a waste wood, a cornstalks, a cornstalks, The dust powder 2 or the crushed material of the crude marble filled in the first feed hopper 11 is introduced into the first pyrolysis reactor 21 of the hybrid fluidized bed pyrolysis reactor 20, The dust powder 3 or the crushed material of the waste acrylic resin contained in the second feed hopper 12 is supplied to the second pyrolysis reactor 22 in the hybrid fluidized bed cracking reactor 20 and is supplied to the third feed hopper 13 Biomass such as waste wood The resource crushing material 4a is introduced into the third pyrolysis reactor 23, respectively.

The hybrid fluidized-bed pyrolysis reactor 20 includes three separate pyrolysis reactors 21, 22 and 23 in an outer housing 20a which is heat-treated with a heat insulating material. The three pyrolysis reactors (21, 22, 23) have the same structure as the actual pyrolysis reactors (21, 22, 23), but are operated separately according to the properties of the material to be treated. The rapid pyrolysis is characterized in that the materials in the material to be treated are gasified in a short time of 5 seconds or less at a temperature of 400 to 550 ° C. Since the amount of heat applied for rapid pyrolysis varies depending on the material to be treated, The amount of heat input and the temperature inside the reactor must be precisely controlled. That is, since the state of each reactor must be maintained in a state suitable for rapid pyrolysis of recycled materials having completely different physical properties, the three pyrolysis reactors present in the hybrid fluidized bed pyrolysis reactor 20 of the present invention are independent of each other After the gas generated by the pyrolysis has escaped, all of the gases are collected as a single route and passed to the cyclone 30 and the hot filter 40 as solids separation means.

In FIG. 2, the first pyrolytic reactor 21 in the hybrid fluidized bed pyrolysis reactor 20 receives the crude marble and performs rapid pyrolysis at a temperature of 400 to 550 ° C. As a result, the raw material Methyl methacrylate (MMA) and aluminum hydroxide (Al (OH) ₃ ) are decomposed into polymethyl methacrylate (PMMA), aluminum oxide (Al ₂ O ₃ ) and water (H ₂ O) (PMMA) and water (H ₂ O) are in a gaseous state and are passed through the first gas transfer line 191 to the cyclone 30, and the aluminum oxide is still in a solid state and is introduced into the first pyrolysis reactor 21 And some of the aluminum oxide dusts are carried on the gas of polymethyl methacrylate (PMMA) and water (H ₂ O) together to the cyclone 30. Aluminum oxide generated by pyrolysis in the first pyrolysis reactor 21 is left in the first pyrolysis reactor 21. The first pyrolysis reactor 21 is a fluidized bed serving as a medium for pyrolysis of the fluidized bed, The aluminum oxide newly added by the pyrolysis of the fluidized silica and the pyrolysis of the crude marble is all made of the same material so that it can be removed at an appropriate amount through the discharge pipe 213 of the first pyrolysis reactor 21 at any time. Further, when sand is used as the fluidized bed of the first pyrolysis reactor 21, the density of aluminum oxide (3.95 g / cm 3) is much larger than the density of sand (2.5 g / cm 3) The aluminum oxide continuously produced by the first pyrolysis reactor 21 sinks downward due to the difference in density with the fluidized sand (sand). At this time, aluminum oxide is taken out through the discharge pipe 213 installed at the lower end of the first pyrolysis reactor 21 You can give it.

Next, the second pyrolytic reactor 22 in the hybrid fluidized bed pyrolysis reactor 20 receives the waste acrylic resin and rapidly pyrolyzes it at a temperature of 400 to 550 ° C. As a result of the pyrolysis, the acrylic resin contains methyl methacrylate (PMMA) and water (H ₂ O). Since polymethyl methacrylate (PMMA) and water are in a gaseous state, they pass through the first gas transfer line 191 to the cyclone 30. In addition to methyl methacrylate (MMA), an acrylic resin contains additives for the function of the product, a reinforcing agent, and a small amount of filler. These additives go into a gas state by pyrolysis and are transferred to the cyclone 30 together with other gases Or may be mixed in the fluidized yarn 22c in a solid state. The solid components resulting from the pyrolysis of the acrylic resin in the second pyrolysis reactor 22 together with the flow yarn 22c escape to the discharge pipe 223 and are stored in the discharge reservoir 224 and then subjected to appropriate classification and recycling processes Lt; / RTI >

Meanwhile, the third pyrolysis reactor 23 in the hybrid fluidized-bed pyrolysis reactor 20 receives biomass lumps such as waste wood, cornstalks, cornstalks, and rice straws and rapidly pyrolyzes them at a temperature of 400 to 550 ° C., The gas containing the oil component and the water vapor pass through the first gas transfer line 191 to the cyclone 30. The solid state materials generated by the rapid pyrolysis of the biomass are present in the third pyrolysis reactor 23 together with the fluid yarn 23c and these solid state materials are mainly ash, Is discharged to the outside through the discharge pipe 233 at the lower end of the second discharge pipe 23, is stored in the third discharge reservoir 234, and is later disposed of by an appropriate sorting process or waste disposal process.

Referring to FIG. 2, the hybrid type recycling treatment system of the marble, acrylic, and biomass using the fluidized-bed rapid pyrolysis technology according to the present invention will be described in detail. First, the fabrication and processing companies of artificial marble, The waste marbles collected in the first feed hopper 11 are crushed to a predetermined particle size or less and put into the first feed hopper 11. It is preferable that the particle size of the crushed materials is maintained at a size of about 3 mm or smaller so that the crushed materials of the crushed marble are smoothly fluidized in the first pyrolysis reactor 21 and pyrolysis is performed. In the process of producing artificial marble products in Korea, the amount of artificial marble dust powder produced by cutting, polishing, and processing operations is as large as 10% of the total artificial marble production. Therefore, when such dust powder is used This is because the particles of the crude marble are within 3 mm, so that no separate crushing process is required. However, when such dust powder is not used, it is necessary to finely crush the marble as a granule with a particle size of 3 mm or less to realize rapid pyrolysis. When the size of the marble particles is large, the temperature gradient between the surface temperature of the particles and the temperature inside the particles is generated and the rapid pyrolysis can not be performed. This is also true in the case of acrylic resin and biomass, and acrylic resin and biomass resources also need to be broken into small particles for rapid thermal decomposition. Particularly, in the case of the biomass, when the moisture is present, the performance of the rapid thermal decomposition is lowered. Therefore, after the crusher 5 is crushed to a small size, moisture is removed from the drier 6 so that the moisture content is at most 10 wt% After the pretreatment, the dried crushed material 4a is stored in the third supply hopper 13 and stored.

The first feed hopper 11 is manufactured in the form of a tank, and a stirrer is installed in the inside of the first feed hopper 11 to mix the pulverized materials of the crude marble as appropriate. In FIG. 2, the agitator is not shown in the first feed hopper 11 for convenience. In the case of the other supply hoppers, that is, the second supply hopper 12 and the third supply hopper 13, an agitator may be provided. In the drawings of the present invention, the agitator is omitted for the sake of convenience.

The crushed product 2 of the crude marble which is the waste contained in the first feed hopper 11 is introduced into the first pyrolysis reactor 21 by the first screw feeder 111 connected to the lower part of the first feed hopper 11 . The first screw feeder 111 includes a screw conveyor 111b (see FIG. 5) rotatably installed in a tube-shaped passage and a first screw driving motor 111a for rotating the screw conveyor 111b.

The waste acrylic resin waste 3 enters the second screw feeder 121 through the lower outlet pipe 12c and the waste acrylic resin waste 3 enters the second screw feeder 121 through the lower outlet pipe 12c. 2 screw feeder 121 is driven by the second screw driving motor 121a to inject the waste acrylic resin waste 3 into the second pyrolysis reactor 22. [

Subsequently, the third feed hopper 13 is filled with biomass pulverization products 4a such as wood pulp, is poured into the third screw feeder 131 through a discharge pipe 13c under the third feed hopper 13, And is introduced into the third pyrolysis reactor 23 by the third screw feeder 131 by the operation of the third screw drive motor 131a.

Since all of the rapid thermal decomposition reactions proceeding in the first to third thermal decomposition reactors 21, 22, and 23 proceed in an oxygen-free atmosphere, nitrogen (N ₂ ). That is, all of the objects to be recycled are stored in a nitrogen atmosphere by injecting the nitrogen filled in the nitrogen tank 7 into the first to third supply hoppers 11, 12, 13 and the first to third thermal decomposition reactors 21, 22, 23).

The first 1-1 valve 161a is provided between the nitrogen tank 7 and the first feed hopper 11 to control the supply of nitrogen gas and the second feed hopper The first-second valve 161b is provided between the first supply hopper 13 and the first supply hopper 13 and the first-third valve 161c is provided between the third supply hopper 13 and the third supply hopper 13, .

2, the three pyrolysis reactors 21, 22 and 23 in the hybrid fluidized bed pyrolysis reactor 20 each have outer surfaces of the reactor housing surrounded by electric heaters 21a, 22a and 23a, The electric heaters 21a, 22a and 23a are rapidly heated to a high temperature of 400 to 550 ° C by the high voltage and high power generated by the first to third high power generating devices 210, 220 and 230. Temperature sensors 21d, 22d, and 23d are installed in the first to third thermal decomposition reactors 21, 22, and 23, and the temperature sensors 21d, 22d, and 23d The internal temperature of the pyrolysis reactors is maintained in an appropriate range based on the signal, and the operation of the first to third high power generating devices 210, 220 and 230 is controlled.

Each of the valves installed in the hybrid type recycling system of the waste marble, acrylic and biomass using the fluidized bed rapid pyrolysis technique of the present invention can be remotely controlled by being connected to a central control device, and the temperature sensors 21d, 22d, and 23d are also input to the control device so that the control device can control the degree of operation of the high power generating devices 210, 220, and 230.

2 and 3, the inner diameter of each of the first to third thermal decomposition reactors 21, 22 and 23 is preferably 20 to 70 cm, more preferably 30 to 50 cm. It is advantageous. The total height of the first to third pyrolysis reactors 21, 22 and 23 can be set in a range of 3 to 10 times the diameter, and particularly preferably, when the diameter is 50 cm, It is preferable to set it to about 3 meters.

The gas injection plates 212, 222 and 232 having a planar shape are installed in the first to third pyrolysis reactors 21, 22 and 23, and the gas injection plates 212, The flow threads are caused to bubble by the pressure of the gas injected from the gas injection nozzles 215, 225, and 235 installed in the bubbles 222 and 232. By the bubbles generated by the bubbling flow, The marble crushed material, the waste acrylic crushed material and the biomass crushed material are respectively introduced into the fluidized bed, and the pyrolysis fluid is rapidly transferred to the pyrolysis furnace.

The three pyrolysis reactors 21, 22 and 23 are operated separately from each other in the hybrid fluidized bed pyrolysis reactor 20 but the gas discharge tubes 21e, 22e and 23e They are merged into one pipeline 191 and passed to the cyclone 30. Each of the valves 162a, 162b and 162c is installed in the gas discharge pipes 21e, 22e and 23e formed in the upper part of the pyrolysis reactors 21, 22 and 23, And the flow rate can be adjusted by the third valve 163 after being combined into one pipe.

The gases entering the cyclone 30 are swirled by the cyclone principle as the solid particles rotate inside the cyclone and the heavy particles sink downward and only the gas components pass through the upper gas outlet and pass to the hot filter 40 Goes. In the cyclone 30, char and aluminum oxide components as solids are discharged through a discharge pipe formed at the bottom. Charcoal is filtered by the solids filter portion 31 to be discharged to the first solids reservoir 33, The aluminum component is collected in the second solids reservoir 34. In the solid filter portion 31, there is a char filter 32 made of a metal net. The char filter 32 separates the char component from the char filter 32.

The hot filter 40 includes a filter element 40b (see FIG. 9) therein, and the filter element 40b separates the solids component once more. The cyclone 30 and the hot filter 40 are connected by a second gas transfer line 192.

Next, the gas leaving the hot filter 40 is rapidly condensed by the condensing means 50 and is converted into a liquid state. The condensing means 50 has a structure in which a plurality of condensers 51, 52, 53 and 54 are connected in parallel and gas is introduced into at least one of the condensers to cause condensation, When the condensed liquid is full, the gas is introduced into the other condenser. That is, since the valves 164a, 164b, 164c and 164d are respectively provided at the openings of the condensers 51, 52, 53 and 54, by the operation of the valves 164a, 164b, 164c and 164d It is possible to determine which condenser will cause the gas to enter. Each of the condensers 164a, 164b, 164c and 164d is provided with a gas cylinder and a tube 501 at the center thereof, and a chiller jacket 502 surrounds the gas cylinder and the tube 501, Since the chiller jacket 502 is filled with the refrigerant circulated and supplied by the chiller supply device 56, the gas in the gas container and the pipe 501 is quickly condensed and changed into a liquid state by the heat exchange action with the refrigerant. , 164b, 164c and 164d, respectively, are collected in the oil water separators 504 below them, and in the oil water separators 504, the liquid components are stacked by specific gravity, Liquids can be separated and recovered in a manual manner.

In the present invention, bio-oil, water, and methyl methacrylate (MMA) are obtained by condensing the gas generated by rapid thermal decomposition. Of these, bio-oil contains moisture and various organic materials, And the specific gravity of methyl methacrylate (MMA) is about 0.92 to 0.95. Therefore, the liquid stacked by the water-oil separator 504 has the bio-oil layer positioned at the bottom, on which water is located, and methyl methacrylate (MMA) is located on the top. Therefore, when the liquids are separated by the interfaces of the liquid from the oil / water separator 504 in an automatic or manual manner, it is possible to separate and recover the bio-oil, water and methyl methacrylate, respectively.

There is still a component that is not condensed and remains in the gaseous state even after most of the liquid in the condensers 164a, 164b, 164c, 164d has been condensed, and these gaseous components are present in the fourth-1 gas transfer line 194a, 4-2 gas transfer line 194b, the 4-3 gas transfer line 194c and the 4-n gas transfer line 194d, and then transferred to the electrostatic precipitator 60.

That is, the gas passing through the first gas pressure regulator 76a is transferred to the first to third supply hoppers 11, 12 and 13 through the 6-1 gas transfer line 196a, The gas passing through the gas pressure regulator 76b is delivered to the first to third screw feeders 111, 121 and 131 through the sixth gas transfer line 196b and supplied to the third gas pressure regulator 76c Are supplied to the first to third gas injection plates 212, 222 and 232 through the sixth gas transfer line 196c, respectively.

On the other hand, since the aluminum oxide discharged from the first pyrolysis reactor 21 and the aluminum oxide separated from the cyclone 30 are not fired, the particles of aluminum oxide are coated with carbons, The utilization rate drops. Therefore, it is necessary to burn off the carbon components coated on the surfaces of the aluminum oxide particles, and this firing operation can be carried out directly in the separately provided firing furnace 90. The firing furnace 90 is a kind of electric furnace in which an electric heater is provided outside the firing furnace 90 and is heated to a high temperature of about 750 to 900 DEG C by using electricity provided by a high power generating device (not shown).
