Description
A Method for Treating Waste Plastic
[Technical Field]
This invention regards to the methods and device for treating waste plastic. In detail, the invention device and method re-manufactures waste plastic without creating any harmful pollutants, treating the waste plastic completely while obtaining clean alternative energy, H2 gas, as by-product.
[Background Technology]
The rapid development of the oil industry after the World War II has provide the humanity with various conveniences, among which the development of technology to convert such substances as C6H6 and C2H4 into C6H5CHCH2 (Styrene Monomer) has enabled us to enjoy the era of plastic. In addition, infinite electric energy due to development of atomic power generation has made the human race materialistically affluent.
However the rich materialistic life has also bestowed difficult and deadly problems. Along with the exhaustion of resources, breakdown of oxygen and by-products such as dioxin from the vast amount of incinerated wastes and burning of fossil fuels, exhaust gas from motor vehicles, various toxic gases from thermal power generation facilities, are causing the disruption of natural harmony - lack of oxygen in the atmosphere, change in weather around the globe, soil pollution, water pollution, marine pollution, destruction of the ozone layer, and thawing of the ice in the north and south poles and alps. This not only creates diseases in plants and animals but also causes mutations of plants and animals and deadly obstinate diseases in humans, putting the whole biological world at risk of extinction. Without fundamental change in human perception, and innovative in environmental technology along its worldwide application, this disastrous scenario will be the downfall of earth. As a pressing issue, in order to protect the ozone layer and prevent the contrary effects of the global weather change we must stop using fossil fuels and suspend the incineration of wastes. Also, to prevent the exhaustion of natural resources, we need to collect and recycle the once used material according to composition elements, and convert or re-manufacture the material into useful and harmless material. In order to solve this difficult problem, new innovative technology must meet these three following conditions.
First, wastes such as trash should be collected based on their chemical components rather than according to types of treatment facilities such as secure landfill or control type landfill (leachate treatment facility, gas flaring, steam supply power generation, refuse derived fuel
treatment facility). The wastes need to be converted into useful and harmless material through new measures based on material compound compatible temperature.
Second, in accordance with the exhaustion of fossil fuels, the technology shall produce better and harmless clean energy that can replace existing fossil fuel. Third, during the combustion process no harmful matter should be discharged and the material should be converted to useful material. The aim is to use a method of recycling or re- manufacturing rather than consuming existing material.
Generally industrial plastic or household plastic is treated based on the possibility of reuse. Among the unusable waste plastic, incorrodible plastic is incinerated or fused to solids to be used as construction material, but as further use is unattainable it is incinerated in the end.
Waste plastic incineration or combustion process discharges an abundance of dusts and harmful gases (CO, CO2, HCN, NO2, NH3, NOx, CH3, etc.) with dioxins (CH3Cl, CCl2F2, CCl4, CH3CCl3, CHBr3, CH3Br, etc.) which are the major causes of environmental pollution. Especially, substances such as dioxins have deadly effect on humans, plants and animals. The resulting ClOx and BrOx from the incineration of waste plastic do not dissolve in the air, and when it reaches the ozone(O3) layer it destroys it. Oxide compounds such as CO, CO2 and NO2 from incineration facilities, thermal power plants and various engines cause the green house effect on the earth's surface resulting in the global warning. Global warming causes the thawing of ice and snow in the poles and the alps, bringing about submersion of lowlands and various natural disasters such as the super typhoon in the US and spreading of deserts in the continents, placing earth on the brinks of destruction.
Dioxin is produced at about 350-750 °C, and is destroyed at over 750 °C . However when plastic is incinerated at over 400 °C dioxin is already produced, so in order to retain and breakdown the dioxin the costs of waste plastic treatment will increase substantially. In addition, if the waste plastic is not compound properly, sections with low temperature can occur which makes it difficult to increase regularly the overall temperature over a certain degrees.
In addition, when the incineration is conducted at over 3800C (ignition point of chemical substance 270 °C) all organics such as wood or textile is complete burnt but chemical material such as synthetic resins will not completely incinerated producing harmful gases such as dioxin type gases.
To solve this problem, technology suggesting recycling or separate incineration of material in categories of mineral matter such as sand or concrete, organic matter, and chemical matter was introduced. However it reality it cannot be attained due to high increase in waste treatment costs based on the higher input of time and effort during the categorizing phase.
Accordingly, with the support of G-7 countries, South Korea, UN and IMF, there were efforts to compound crude oil with the thermal decomposition technology. However the separation of isomers was difficult and large amount of manpower was consumed due to cogging in the machinery. With the production of crude oil were less than 30%, generation of huge amounts of harmful gasses and cinder (25%), the technology turned out to be economically inefficient. O December 30, 2005 in Japan, through the GE DO report the project was announced as unsuccessful.
Meanwhile, because of the draining fossil fuels and discharge of harmful gasses, countries around the world are trying to produce hydrogen energy. Based on the electrolysis of H2O, they tried to substitute H2 as clean energy source but the price of H2 per It was 15, 000 won, 10 times the price of fossil fuel, making the commercialization of the fuel far off.
According to the results of numerous researches on the diverse problems of the existing waste plastic treatment, the inventors of this innovation have developed a method to completely re-manufacture waste plastic without categorizing, incinerating or thermal decomposition.
[Disclosure of Invention]
[Subject Task]
The aim of the invention if to provide a method and device for treating waste plastic completely into reusable fuel without creating harmful substances while obtaining clean alternative energy, H2 gas, as by-product.
[Task Solution Measures]
The purpose of the invention, as stated above, is to fuse simultaneously the low density, high density, and highly complex plastic materials in vacuumed conditions. Consequently, neither combustion nor harmful gases are generated. The fused plastic liquid compound is synthesized with H4 and C6H6 at the distillation column of the pressure transfer device, producing styrene monomer while generating H2 as by-product.
The invention follows the following stages. Waste plastic shredding stage; shredded waste plastic input stage; induce deliquescence substance fusion stage (hydrogen molecule separation methods of apply heat through ceramic heater, pressure friction heat, dielectric heating device); hydride reaction stage (apply alumina ionophore to fusion substance inducing hydride reaction); deliquescence crystallization stage (decompression and distillation device); C2H4 and C6H6 synthesis stage (cooling of the deliquescence crystals)
In this invention 'hydrogen molecule separation method' means applying high voltage electricity of 3kW and mega high frequency of 2,350MHz to the molecule substance through dielectric heating device, starting the rotation movement the H molecule increasing the molecule friction energy, and ultimately separating the C and H molecules through sudden increase of internal friction energy. In other words, by applying alternating electricity current at the high density molecule substance, alternating the negative and positive terminal, + molecule will arrange itself at the negative electricity and - molecule at the positive electricity. If the process is rapidly and continuously inflicted the substance will create internal friction heat causing the separation of C and H molecule. The 'deliquescence substance' in this invention means a liquid form substance that is a melted compound of isomer material with different melting points.
The 'deliquescence crystal' in this invention refers to useful and beneficial substance that is created through deliquescence substance's hydride reaction at compatible temperature.
The material applicable to this waste plastic treatment invention includes various types of plastic material such as low density plastic (PC, PE), high density plastic (polymer, nylon, various types of films) and complex plastic (PVC, ABS).
According to this invention, there is no need to artificially separate the various plastic materials. The plastic materials can be put into the waste plastic treatment device simultaneously or separately. Through the heating process of ceramic heating, pressure friction heating and hydrogen molecule separation the low density plastic will start to separate and liquefy at around
110 -130 °C, the high density plastic at around 180~210°C , and complex plastic at around
170-1800C . As there is less molecules in low density plastic, amounting to under 500, the plastic starts to melt by the heat of the ceramic heater at the temperature of 130 °C , even without the help of hydrogen molecule friction heat. High density plastic holds a high number of molecules counting over 15,000 and it starts to melt at the temperature of 220 °C, which is the sum of ceramic heater heat of 130°C and internal frication heat of the hydrogen molecule of 90 °C . The complex plastic holds about 5,000 molecules and with the external heat provided by the ceramic heater of 130°C and internal frication heat of the hydrogen molecule of 40 °C, the plastic starts to melt at 170°C . Hence, in this invention low density plastic, high density plastic and complex plastic does not combust but is liquefied simultaneously creating a compound material.
When 3kW of high voltage electricity and 2,450 MHz of mega high frequency is applied to the above compound material, it causes sudden increase of internal friction energy in the substance resulting in separation of C and H molecules forming a deliquescence substance. In addition, when Al(OH)3 ionophore is inserted into the deliquescence substance, hydride reaction occurs, and by reducing pressure to -40 mm Aq through the decompression distillation device the
temperature increases an additional 108°C, reaching an overall temperature of 378 °C, ultimately attaining the compatible temperature(370°C~380°C) of C and H, resulting in deliquescence crystallization of the molecules. Through cooling process C6H6 and C2H4 is synthesized. A lighter C2H4 and heavier C6H6 is separately obtained. With polymer catalytic reaction C6H5CHCH2 resin can be manufactured while producing clean energy H2 gas as by-product.
The process of deliquescence of low density, high density and complex plastic through thermal equilibrium chemical reaction in this invention is as follows.
The control box heats the exterior of the fusion container through electric ceramic heater and when the temperature reaches 270 °C it applies pressure of 200HP at the pressure operation control and inputs the waste plastic at the material infusion entrance.
When the 3 kW of high voltage electricity and 2450MHz of mega high frequency is projected to the waste plastic through dielectric heating system, the temperature of the internal friction heat in the hydrogen molecule increases rapidly causing the separation of C and H molecule and liquidation of the plastic. The low density macro-molecule substance is not influence by the dielectric heating and there is no internal friction energy, so the free energy decreases while the entropy increases. While the high density macro-molecule substance absorbs the friction energy made by the fusion container's screw rotation and pressure, thus increasing its free energy.
When the fusion container's screw is rotated at the speed of 30 times per minute, the substance in each group of waste plastic passes through the fusion container. At the 1st stage of dielectric heating, at the temperature of 130 °C, the low density substance is fused. During the 2nd stage, adding to the temperature of 130°C, there is an increase of 90 °C due to 3 kW of high voltage electricity and 2450MHz of mega high frequency projection, resulting in overall temperature of 220 °C causing the fusion of high density macro-molecule substance, and the whole substance is finally liquefied into one substance of one disposition.
The liquid substance is in a state of C and H molecule separation at the temperature of 270 °C . When the substance is transferred into the decompression distillation device by Al(OH)3 ionophore and decompressed with -40 mmAq, the temperature of the distillation column increases to 370 ~ 380°C attaining the compatible temperature of C and H. In the distillation column C6H6 and C2H4 is synthesized, distilled and transferred to cooling device finally producing C6H6 and C2H4
There is chemical reaction caused by the substance's molecule friction heat. According to the second law of thermodynamics, namely the law of increase of entropy, the heat moves from the higher side to the lower side resulting in thermal equilibrium state. Free energy, that works
effectively during continuous chemical reaction, increases and decreases converting the isomer substance into a substance of identical disposition in a state of thermal equilibrium.
In addition, the invention provides a waste treatment device using the above waste treatment method. The invented waste treatment facility is composed in to 1st treatment section, 2nd treatment section and 3rd treatment section. The 1st treatment section is equipped with the following. Vertical infusion passage with a perpendicular funnel; transfer screw that rotates the internal axis of the vertical infusion entrance; horizontal infusion passage equipped with a horizontal funnel connecting to the vertical infusion passage, and a waste plastic input entrance; horizontal transfer screw enabling the rotation of the axis in the horizontal infusion passage; ceramic heater installed at the exterior of the horizontal infusion passage; and dielectric heating device for high density chemical substance.

[Best Mode for Carrying Out the Invention]
As the attached drawings of preferable application, below is the detailed description of the invention. However the application of the invention is not limited to the stated scope.
As shown in Drawing 2, waste plastic is put into the horizontal infusion passage(40), the plastic then flows through the upper pressure passage(l 1) into the vertical infusion passage(30), during this process the waste plastic is pressured into moving into the upper pressure passage(l 1) by horizontal transfer screw(41) and vertical transfer screw(31). At the upper pressure passage(l 1), in vacuum state, pressure friction heat is created due to the rotation of the pressure transfer screw(15). I addition, heat from the ceramic heater and friction heat within the waste plastic substance molecule dielectric heating device cause the fusion of the plastic resulting in a liquid compound.
It is favorable to install the vertical transfer screw(31) according to the direction of the vertical infusion passage(30) axis enabling the input of waste plastic from the side.
It is preferable to install at least more than one, preferably 4, horizontal infusion passage(40) across the vertical infusion passage(30), so that gel form waste plastic is supplied through the vertical infusion passage(30). It is possible to place many number of horizontal infusion passage(4) on the vertical infusion passage(30) in certain intervals. In this case, as waste plastic is supplied through many passages into one passage, intensely pressured waste plastic is supplied into the pressure passage(l l). The transfer screw on the horizontal infusion passage(4) enables the movement of the waste plastic. While transferring the waste plastic, the upper pressure infusion passage(l 1) increases the temperature of the waste plastic through ceramic heater, dielectric heating device, and friction heat within the waste plastic substance molecule. As all low density, high density, complex macro-molecule substance need to be fused simultaneously by increasing the temperature of to the melting point, before the substance is discharged, it is preferable to install more than one transfer screws so that the temperature and pressure speed can be controlled separately.
It is preferable to place numerous transfer screws horizontally in certain intervals on the upper pressure passage(l l) and the horizontal infusion passage(40) to maximize the compound process and friction of the waste plastic.
As displayed in Drawing 2, the upper vertical infusion passage(30) is placed perpendicular to the waste plastic infusion entrance(13) of the pressure passage(l l). Internally, the vertical transfer screw(31) enables the rotation of the axis, and it is controlled by the vertical operation control(32).
As seen in Drawing 3, there are 4 horizontal infusion passages(40) on the outer axis of the upper vertical infusion passage(30). It is placed in certain intervals in radial form. There are horizontal transfer screws(41) installed inside each horizontal infusion passage(40) enabling the
rotation of each axis. Each horizontal transfer screw(41) is operated by each horizontal operation control(42). There is waste plastic input entrance(40a), vacuum pump (20), ceramic heater (40-1), dielectric heating device(40b), water vapor exhaust outlet(40c) installed on the sides of each horizontal infusion passage(40). The waste plastic, coming through the waste plastic input entrance(40) of the upper horizontal infusion passage(40), is transferred to the vertical infusion passage(30) by the horizontal transfer screw(41). As the waste plastic is transferred through 4 horizontal infusion passages(40) simultaneously to the single vertical infusion passage(30), the vertical infusion passage(30) is supplied with gel form waste plastic. Meanwhile, as the inside of the upper pressure passage(l 1) holds no air due to the vacuum pump(20-l), waste plastic is transferred from upper vertical infusion passage(30) to pressure passage(l 1) through external pressure.
In a state of vacuum induced by the vacuum pump(21), the waste plastic, going through the 4 horizontal infusion passages(40), is fused and deliquesced by friction of the horizontal transfer screw(41), friction heat through pressure, increase of heat by external ceramic heater(40-l) and friction heat in the internal molecule by dielectric heating device(40b). The waste plastic transferred to the vertical infusion passage(30) is then sent to the pressure passage(l 1) by the vertical transfer screw(31). As the waste plastic goes through the vertical infusion passage(30) the temperature increases due to the friction and pressure of the vertical transfer screw(31 ). As the waste plastic supplied to the vertical infusion passage(30) by the 4 vertical infusion passages(40) is an intensely pressured state, the waste plastic or internal liquid cannot flow out.
Only the water vapor generated from the waste plastic in the horizontal infusion passage(40) can be discharged through the waste plastic input entrance(40a) and water vapor exhaust outlet(40c).
In the 4 horizontal infusion passages(40), moisture from mineral matter such as soil, sand, and concrete, and organic matter such as wood and textile evaporates and dries up. While going through the vertical passage(30) the internal temperature continuously increases and the waste plastic substance starts to fuse. The gel form hydrocarbon compound is pushed into the vertical infusion passage(30) and the chemical material that is not made into gel form is put into the pressure passage(l 1) in solid form. As illustrated in Drawing 2, the upper pressure passage(l l) consists of upper vertical infusion passage(30), pressure passage(l 1), vacuum pump(20-l), dielectric heating device(12-l), hydrogen reactor(l l-l) of 500mm in length, and fringe connection(18). In addition, at the upper section consists of Al(OH)3 ionophore alumina insert (12), ionosphere passage distillation column(16), and pressure device(14) to transfer ionosphere into the distillation column.
At the upper pressure passage(l l), one pair of pressure transfer screws(15) are installed to enable the rotation of the axis. The upper pressure transfer screw(15) is controlled by the pressure operation gear(17).
On the side of upper pressure passage(l l) there is an infusion entrance(13) for gel state waste plastic. It receives waste plastic gel from the upper vertical infusion passage(30) and as the waste plastic gel moves through the pressure passage(l l) the remaining moisture is discharged by the vacuum pump(20-l). By increasing the heat through the ceramic heater(40-l) and causing hydrogen molecule separation by internal molecule friction through dielectric heating device(12-
1), the waste plastic in the vacuum is completely liquefied. After the liquidation process, the substance is moved to the distillation column(16) with Al(OH)3 as ionosphere.
Based on the principle of ascent in decompression temperature of the distillation column, at the compound compatible temperature(370°C~380°C) Of C6H6 and C2H4, the transferred waste plastic in the distillation column(16) is discharged separately as lighter substance Of C2H4 (16-1) and heavier substance OfC6H6 (16-2).
