본 발명은 폐플라스틱 필름을 이용한 고열량의 왁스의 제조장치에 관한 것으로, 더욱 상세하게는 농업용 폐플라스틱 필름과 같은 열가소성 폐플라스틱을 용융조에서 불순물과 분리한 후 이를 다시 열분해(thermal degradation)하여 고부가 왁스(wax)를 제조하는 방법 및 장치를 제공하는 것이다. The present invention relates to an apparatus for producing a high-calorie wax using waste plastic film, and more particularly, to separate thermoplastic waste plastic such as agricultural waste plastic film from impurities in a melting bath and thermally decompose it again to add high-wax wax. It is to provide a method and apparatus for producing (wax).

현재, 농작물 생육촉진 및 잡초제거 등을 위해 사용 후 버려지는 농업용 폐플라스틱 필름의 양은 매년 증가하여 2000년에는 238천톤에 이르며 이중 114천톤은 자원재생공사와 민간 수집상에 의해 수거되고 124천톤(52%)은 불법소각 또는 방치되고 있어, 폐플라스틱 필름의 처리가 시급한 실정이다. At present, the amount of waste plastic film discarded after use to promote crop growth and weed removal increases every year, reaching 238 thousand tons in 2000, of which 11,000 thousand tons are collected by reclamation works and private collectors and 124 thousand tons (52%). ) Is illegally incinerated or left unattended, and the disposal of waste plastic film is urgent.

또한 폐플라스틱 필름의 처리방법 중의 하나인 매립의 경우 매립지 확보에 어려움이 있으며 폐플라스틱 필름이 부피가 크고 분해되지 않기 때문에 2차 환경오염의 문제점을 가지고 있으며, 소각의 방법은 고비용의 에너지 소비와 다이옥신 같은 환경 유해물질이 배출되는 문제점이 있다.  In addition, in the case of landfill which is one of the disposal methods of waste plastic film, it is difficult to secure landfill, and since waste plastic film is bulky and does not decompose, there is a problem of secondary environmental pollution, and incineration has high energy consumption and dioxins. There is a problem that the same environmental harmful substances are emitted.

따라서 이러한 단점을 제거한 처리방법이 재활용 방법으로 재활용 방법의 경우 화학적 리사이클(chemical recycle), 물질적 리사이클(material recycle)과 같은 방법으로 최근 활발한 연구가 이루어지고 있으며 이중 오일을 제조하는 화학적 리사이클기술의 경우 물질적 리사이클에 비해 매년 그 연구의 필요성이 증대하 고 있고 여러 분야에서 연구가 활발히 진행되고 있다.  Therefore, the treatment method that eliminates these shortcomings is the recycling method. In the case of the recycling method, active researches have recently been conducted by methods such as chemical recycle and material recycle, and in the case of chemical recycling technology for producing double oil, Compared to recycling, the need for the research is increasing every year, and research is being actively conducted in various fields.

하지만, 기존의 폐플라스틱 필름의 촉매 사용 열분해 방법은 저온 분해가 가능하며 균일한 분해 생성물을 얻을 수 있어 가솔린 범위의 고부가 가치 생성물을 얻는 장점이 있지만 사용촉매가 고가이고 사용이 제한되어 있어 폐플라스틱 필름의 처리에는 많은 문제점이 있다. 또한 기존의 폐플라스틱 분해공정은 열분해 반응기에 투입되는 폐플라스틱 필름의 세척과정이 필수적으로 요구되며, 그 과정에서 발생하는 폐수는 2차 환경오염을 일으키므로 많은 문제점이 있었다. However, the catalyst-based pyrolysis method of the conventional waste plastic film is capable of low-temperature decomposition and obtains a uniform decomposition product, thereby obtaining a high value-added product in the gasoline range, but the catalyst used is expensive and the use of the waste plastic film is restricted. There are many problems with the treatment of. In addition, the existing waste plastic decomposition process is required to wash the waste plastic film that is introduced into the pyrolysis reactor, and the waste water generated in the process has a lot of problems because the secondary environmental pollution.

따라서, 본 발명은 상기 종래 기술의 문제점을 해소하기 위한 것으로, 수거된 농업용 또는 산업용 폐플라스틱을 처리공정중 수세 및 건조공정이 없이 용융조에 직접 투입하여 용융조에서 폐플라스틱의 용융물과 폐플라스틱에 함유되어 있는 불순물을 분리하고, 분리된 플라스틱 용융물은 다시 열분해 반응조에 투입하여 열분해 함으로써 고열량 고부가가치의 왁스를 제조함으로써, 기존 공정과 달리 환경오염에 미치는 영향을 크게 감소시키고 폐기물의 효과적인 재활용 방법을 제공하는데 장치 및 제조방법을 제공하는 것이다.
Therefore, the present invention is to solve the problems of the prior art, the collected agricultural or industrial waste plastic directly into the molten bath without washing and drying process during the treatment process contained in the melt and waste plastic of the waste plastic in the molten bath By separating the impurities and the separated plastic melt into the pyrolysis reactor and pyrolysis to produce a high-calorie high value wax, it significantly reduces the impact on environmental pollution and provides an efficient recycling method of waste, unlike the existing process It is to provide an apparatus and a manufacturing method.

상술한 목적을 달성하기 위해 본 발명은, 폐플라스틱의 용융시 일정량의 폴리에틸렌 왁스를 동시에 투입하여 용융조에서 용융하여, 폐플라스틱 필름의 용융뮬 에 함유되어 있는 흙이나 돌 등의 불순물을 비중의 차에 의해 용융조의 하부로 배출시키고, 폐플라스틱 용융물은 열분해 반응조에 이송하여 고온에서 열분해하여 고부가의 왁스를 제조하는 공정으로 이루어진다. In order to achieve the above object, the present invention, by melting a certain amount of polyethylene wax at the same time when melting the waste plastic, and melted in a melting tank, the difference in the specific gravity of impurities such as soil or stone contained in the molten plastic of the waste plastic film By discharging to the lower part of the melting tank, the waste plastic melt is transferred to a pyrolysis reaction tank and pyrolyzed at high temperature to produce a high value wax.

이하는, 본 발명에 따른 폐플라스틱으로부터 고부가가치의 왁스를 제조하는 장치를 도면을 이용하여 구체적으로 설명한다. Hereinafter, an apparatus for producing a high value added wax from waste plastic according to the present invention will be described in detail with reference to the drawings.

도 1은 본 발명에 따른 폐플라스틱 필름을 이용한 고부가 왁스를 제조하기 위한 장치의 개략도로서, 상부에 폐플라스틱 투입구(5)와 용융교반기(6) 및 불순물배출구(5-1)와 폐플라스틱 용융물이송관(13)을 갖는 용융조(10), 상부에 응축기(3)와 하부에 왁스배출구(8) 및 열분해교반기(14)를 가지는 열분해 반응조(12)를 가진다. 융융조와 열분해반응조는 반응시 모두 질소분위기 하에서 반응이 진행되며, 별도의 도시를 하지 않았지만(통상적인 수단임) 히터 및 온도조절기 및 냉각시스템을 장치하여 적절한 온도로 온도를 조절한다.1 is a schematic diagram of a device for producing high value wax using waste plastic film according to the present invention, the waste plastic inlet (5) and the melt stirrer (6) and impurity outlet (5-1) and waste plastic melt A melting tank 10 having an air pipe 13, a condenser 3 at the top, and a pyrolysis reactor 12 having a wax outlet 8 and a pyrolysis stirrer 14 at the bottom thereof. In the melting tank and the pyrolysis reaction tank, the reaction proceeds under a nitrogen atmosphere, and although not shown in the drawings (normal means), the heater and the thermostat and the cooling system are equipped to control the temperature to an appropriate temperature.

도 1을 구체적으로 설명하면, 먼저, 폐플라스틱 필름을 소량의 왁스와 함께 투입구(5)를 통하여 질소로 퍼지된 용융조(10)에 투입되고, 투입된 폐플라스틱 필름은 250 내지 300℃에서 용융된 후, 흙이나 모래 등의 불순물은 비중의 차이에 의해 용융조의 불순물배출구(5-1)을 통해 외부로 배출되고, 폐플라스틱 필름의 용융물은 폐플라스틱 용융물 이송관(13) 및 밸브(11)을 통해 열분해 반응조(12)로 이송된다. 이때, 용융조(10)는 용융조의 바닥은 일정한 기울임각을 주어 불순물이 한곳으로 모이게 하여 불순물배출구(5-1)에 의해 외부로 배출되어 고체연료등으로 재활용되도록 한다. 상기의 용융조(10)에 투입되는 왁스는 전체투입량의 10 내지 60 중량%가 좋다. 이보다 적을 경우는 불순물의 제거효율이 낮고, 이보다 많을 경우는 폐플라스틱의 활용량이 낮아지는 경향이 있어 경제성이 없다. Referring to Figure 1, first, the waste plastic film with a small amount of wax is introduced into the melting tank 10 purged with nitrogen through the inlet (5), the injected waste plastic film is melted at 250 to 300 ℃ Then, impurities such as soil or sand are discharged to the outside through the impurity outlet 5-1 of the melting tank by the difference in specific gravity, and the melt of the waste plastic film is transferred to the waste plastic melt transfer pipe 13 and the valve 11. It is sent to the pyrolysis reactor 12 through. At this time, the melting tank 10 is a bottom of the melting tank to give a predetermined inclination angle to collect the impurities in one place to be discharged to the outside by the impurity discharge port (5-1) to be recycled as a solid fuel. Wax added to the melting tank 10 is preferably 10 to 60% by weight of the total amount. If it is less than this, the removal efficiency of impurities is low, and if it is more than this, there is a tendency that the utilization amount of waste plastic tends to be low, which is not economical.

열분해 반응조(12)는 열분해교반기(14) 속도를 적절히 유지하고(통상적으로 약 20rpm 정도가 좋다.), 열분해 반응조(12)의 온도를 열전쌍(9)을 이용하여 컨트롤하여 350~390℃로 유지시키고, 질소분위기 하에서 하여 열분해(thermal degradation) 시켜 왁스(wax)를 생성시킨다. 또한, 열분해 반응시 발생한 저 분자량의 오일은 응축기(3)를 통해서 따로 회수할 수 있으며, 용융조(10)의 하부에 배출된 불순물 및 폐 플라스틱 필름은 별도의 공정을 거쳐서 고열량의 고체연료의 제조에 사용될 수 있다. 여기서, 미설명부호 1은 N2가스, 2는 모터, 4는 용광로, 7은 유량계를 나타낸다.The pyrolysis reactor 12 maintains the speed of the pyrolysis agitator 14 appropriately (typically about 20 rpm is preferable), and the temperature of the pyrolysis reactor 12 is controlled by using the thermocouple 9 to maintain the temperature at 350 to 390 ° C. And thermal degradation under a nitrogen atmosphere to produce a wax. In addition, the low molecular weight oil generated during the pyrolysis reaction can be recovered separately through the condenser (3), the impurities and waste plastic film discharged to the lower portion of the melting tank 10 through a separate process to produce a high-heat amount of solid fuel Can be used for Here, reference numeral 1 denotes an N 2 gas, 2 denotes a motor, 4 denotes a furnace, and 7 denotes a flowmeter.

상기 생성된 왁스는 분자량이 대략 1000~5000, 용융점도(140℃)가 300~400cP로서 그 정도가 본 발명에서 요구되는 가장 적정한 분자량 및 점도를 갖으며, 필요에 의해서는 분해하여 왁스를 분리한후 필터링하거나 일정기간 정치하여 사용하면 더욱 좋다.The produced wax has a molecular weight of approximately 1000 ~ 5000, melt viscosity (140 ℃) of 300 ~ 400 cP has the most appropriate molecular weight and viscosity required by the present invention, if necessary decomposes the wax to separate It is better to use after filtering or stationary for a certain period.

다음의 표 1은 폴리에틸렌 폐플라스틱을 이용하여 구체적 실험을 통해 여러 반응조건에 따른 불순물의 제거효율을 나타낸 도표이다.The following Table 1 is a chart showing the removal efficiency of impurities according to various reaction conditions through a concrete experiment using polyethylene waste plastic.

<표 1> 용융조에서의 폐플라스틱의 불순물 제거효율<Table 1> Impurity Removal Efficiency of Waste Plastic in Melting Tank

Figure 112004000532008-pat00001
Figure 112004000532008-pat00001

상기의 <표 1>에서 알 수 있듯이, 왁스를 효과적인 용융을 위해 촉매로 사용했을 경우 300℃ 80분간 반응시켰을 때 폐플라스틱 필름과 불순물의 제거효율을 살펴보면 초기에 왁스와 폐플라스틱 필름의 투입량을 9:1로 한 경우 불순물의 제거효율은 62% 였으며 7:3 이상에서는 90% 이상의 높은 제거효율을 보임을 알 수 있다. 따라서 소량의 폴리에틸렌 왁스를 사용함으로 비교적 단순한 공정으로도 불순물의 제거가 가능함을 알 수 있다. As can be seen from Table 1, when the wax is used as a catalyst for effective melting, the waste plastic film and the removal efficiency of impurities are reacted at 80 ° C. for 80 minutes. In the case of 1: 1, the removal efficiency was 62%, and above 7: 3, the removal efficiency was over 90%. Therefore, it can be seen that by using a small amount of polyethylene wax it is possible to remove impurities even in a relatively simple process.

표 2 는 여러 실험을 통해 생성된 왁스의 평균 분자량 및 점도를 나타내는 도표이다. Table 2 is a chart showing the average molecular weight and viscosity of the wax produced through various experiments.

<표 2>TABLE 2

Figure 112004000532008-pat00002
Figure 112004000532008-pat00002

<표 2>에서 알 수 있듯이, 초기에 용융조에 투입된 왁스의 함량이 증가할수록 생성된 고부가 왁스의 평균분자량 및 점도는 점차적으로 감소함을 알 수 있다. 또한 열분해 반응조에서의 열분해 반응시간을 조절함으로서 평균분자량과 용융점도가 각각 1000~5000cP, 300~400cP인 고부가가치의 왁스를 제조할 수 있음을 알 수 있다.As can be seen from Table 2, it can be seen that the average molecular weight and viscosity of the high value wax produced gradually decrease as the amount of the wax initially added to the melting bath increases. In addition, it can be seen that by controlling the pyrolysis reaction time in the pyrolysis reactor, a high value added wax having an average molecular weight and a melt viscosity of 1000 to 5000 cP and 300 to 400 cP, respectively, can be prepared.

이상에서 설명한 바와 같이, 본 발명은 환경오염의 주범인 폐플라스틱 필름을 전처리 없이 소량의 왁스와 함께 용융조에 투입하여 불순물과 분리하고 이를 다시 열분해 반응조로 이송시켜 비교적 낮은 온도에서 열분해하여 왁스를 제조하고, 용융조에서 배출된 불순물을 고형연료로 제조하고 응축기에서 얻어진 오일을 다시 용융조에 투입하여 효과적인 분리공정을 제공함으로써, 폐자원을 활용할 수 있고, 2차 환경오염을 줄일 수 있어 폐기물의 재활용을 극대화될 수 있는 장점이 있다.
As described above, in the present invention, waste plastic film, which is the main culprit of environmental pollution, is introduced into a melting tank together with a small amount of wax without pretreatment, separated from impurities, and then transferred to a pyrolysis reactor to pyrolyze at a relatively low temperature to produce wax. In order to maximize the recycling of wastes, it is possible to utilize waste resources and reduce secondary environmental pollution by making impurities discharged from the melting tank into solid fuel and putting oil from the condenser back into the melting tank to provide an effective separation process. There is an advantage that can be.
