Description

연속식 열분해기를 포함하는 유화시스템 {Emulsification system containing continuous pyrolysis groups}Emulsification system containing continuous pyrolysis groups}

본 발명은 폐비닐, 폐플라스틱 등의 폐합성수지로부터 열분해유를 추출하기 위한 연속식 열분해기를 포함하는 유화시스템에 관한 것으로서, 열분해기가 연속적으로 배열되면서 유증기를 추출효율을 향상시킬 수 있고, 열분해기 내부에 2열의 스크류가 구비되어 원활한 교반과 더불어 타르 및 분진의 회수가 용이한 연속식 열분해기를 포함하는 유화시스템에 관한 것이다. The present invention relates to an emulsification system including a continuous pyrolysis machine for extracting pyrolysis oil from waste synthetic resin such as waste vinyl and waste plastic. It relates to an emulsification system including a continuous pyrolysis machine equipped with two rows of screws to facilitate smooth stirring and easy recovery of tar and dust.

일반적으로 플라스틱(Plastic)이라 칭하는 합성수지는 석유를 주 원료로 다양한 물질을 중합시켜 성형과 사용자로부터 요구되는 특성부여가 자유롭기 때문에 그 사용량이 급격히 증가되고 있고, 워낙 방대한 분야에서 사용이 가능하여 그로 인한 폐기물의 양도 증가하고 있다. Synthetic resins, generally called plastics, are rapidly increasing in usage because they polymerize various materials with petroleum as the main raw material, and are free to mold and provide characteristics required by users, and can be used in a vast range of fields, resulting in waste amount is also increasing.

특히 연간 1인당 사용되는 합성수지의 양은 2016년을 기준으로 약 98KG을 사용하고 있는 것으로 볼 때 합성수지 폐기물의 처리가 매우 시급한 실정이라 할 수 있다.In particular, considering that the amount of synthetic resin used per person per year is about 98KG as of 2016, it can be said that the treatment of synthetic resin waste is very urgent.

이러한 다량의 폐합성수지는 현재 대부분 소각 및 매립에 의하여 처리되고, 생산되는 합성수지의 양에 비해 매우 일부만 재활용이 이루어지고 있다. 폐합성수지를 소각하는 경우 유독가스로 인해 대기오염의 문제점이 있으며, 매립의 경우 자연분해가 쉽게 이루어지지 않는 합성수지의 특성으로 토양오염의 심각한 문제점으로 자리잡고 있었다. Most of these waste synthetic resins are currently treated by incineration and landfill, and only a small portion is recycled compared to the amount of synthetic resin produced. In the case of incinerating waste synthetic resin, there is a problem of air pollution due to toxic gas, and in the case of landfill, it has become a serious problem of soil pollution due to the nature of synthetic resin that does not easily decompose naturally.

상기의 문제점으로 인해 폐합성수지를 재활용하는 방안이 권장되고 다양한 방법으로 폐합성수지를 재활용하려는 노력이 수반되었다. 특히 석유의 매장량이 축소되면서 가격이 상승하는 실정에 따라 폐합성수지로부터 유류 성분을 추출하거나, 다른 자원으로 재활용할 수 있는 연구가 활발하게 진행되고 있다. Due to the above problems, a method of recycling waste synthetic resin is recommended, and efforts to recycle waste synthetic resin in various ways have been accompanied. In particular, as oil reserves decrease and prices increase, studies on extracting oil components from waste synthetic resin or recycling them into other resources are being actively conducted.

이러한 연구로 인한 종래의 폐합성수지를 재활용하는 기술은 폐합성수지를 작은 크기로 분쇄한 후 다른 재료와 혼합하여 고체연료봉의 형태로 압축 성형하는 기술과 열처리를 통해 폐합성수지을 부터 유류 성분을 추출하는 기술 등으로 나눌 수 있다. 하지만, 고체연로봉으로 재사용하는 방법은 환경호르몬, 대기오염 등의 문제가 발생하였고, 재생 오일을 추출하는 방법은 추출하는 비용에 비해 회수되는 재생오일의 품질 및 생산량이 매우 적어 경제성이 떨어지는 문제점이 지적되었다.Conventional technologies for recycling waste synthetic resin resulting from such research include a technology of crushing waste synthetic resin into small sizes and mixing it with other materials to compress and mold it in the form of a solid fuel rod, and a technology of extracting oil components from waste synthetic resin through heat treatment. can be divided into However, the method of reusing the solid fuel rod has problems such as environmental hormones and air pollution, and the method of extracting recycled oil has a problem of poor economic feasibility because the quality and production of recovered recycled oil are very low compared to the cost of extraction. pointed out

또한, 과거에는 폐합성수지가, PP, PE 재질로 비교적 재활용이 용이하였으나, 근래에는 플라스틱 제조기술이 고도화되면서 PET, ABS, PA, PBT, PPSU 등 다양한 기능성 소재로 제조되어 재활용 공정에 해당하는 전처리과정에서 발생하는 경비가 상당하여 재활용 방법이 매우 까다로워지는 상황에 이르렀다. In addition, in the past, waste synthetic resin was relatively easy to recycle as PP and PE materials, but in recent years, as plastic manufacturing technology has advanced, it has been manufactured with various functional materials such as PET, ABS, PA, PBT, and PPSU, and is a pretreatment process corresponding to the recycling process. Recycling methods have become very difficult due to the significant costs incurred in recycling.

따라서, 폐합성수지의 재료에 상관없이 폐합성수지로부터 재생오일을 간편하게 추출할 수 있으며, 추출되는 재생오일의 품질 및 추출량을 극대화시킬 수 있는 폐합성수지 재활용 방법이 필요한 실정이다.Therefore, there is a need for a waste synthetic resin recycling method that can easily extract recycled oil from the waste synthetic resin regardless of the material of the waste synthetic resin and maximize the quality and extraction amount of the extracted recycled oil.

도 1 및 도 2 를 참조하면 본 발명은 열분해기(100), 응축기(200), 진공펌프(310) 및 저장조(400)를 포함한다. Referring to FIGS. 1 and 2 , the present invention includes a thermal cracker 100 , a condenser 200 , a vacuum pump 310 and a storage tank 400 .

열분해기(100)는 일측으로 폐합성수지가 투입되는 드럼(101)과 드럼(101)의 외측면을 감싸면서 드럼(101)을 가열하는 가열부(120)를 포함한다. 가열부(120)가 드럼(101)에 수용된 폐합성수지를 가열하면 드럼(101)의 내부에서 폐합성수지가 녹으며(열분해) 유증기가 발생한다.The thermal decomposer 100 includes a drum 101 into which waste synthetic resin is injected on one side and a heating unit 120 that heats the drum 101 while covering an outer surface of the drum 101 . When the heating unit 120 heats the waste synthetic resin accommodated in the drum 101, the waste synthetic resin melts (pyrolyzes) inside the drum 101 and oil vapor is generated.

도 7 을 참조하면 가열부(120)는 드럼(101)의 외측을 감싸며 소정의 두께를 가지며, 석면으로 이루어진 석면포(121)와 석면포(121)의 둘레면을 따라 권취되며, 외부로부터 전력을 인가받아 석면포(121)를 가열하는 가열선(122)을 포함한다. 가열선(122)이 전력을 인가받아 열에너지를 방출하면, 열에너지가 석면포(121)을 지나 드럼(101)의 내부로 전달된다. Referring to FIG. 7 , the heating unit 120 surrounds the outside of the drum 101, has a predetermined thickness, and is wound along an asbestos cloth 121 made of asbestos and along a circumferential surface of the asbestos cloth 121, and applies electric power from the outside. It includes a heating wire 122 for receiving and heating the asbestos cloth 121. When electric power is applied to the heating wire 122 and heat energy is released, the heat energy passes through the asbestos cloth 121 and is transferred to the inside of the drum 101 .

그리고, 가열부(120)는 석면포(121)의 양측면에 각각 구비되며, 드럼(101)의 외측면에 고정되는 한 쌍의 고정브라켓(123)과 고정브라켓(123)의 상단에 구비되어 가열선(122)과 석면포(121)가 외부에 노출되는 것을 방지하기 위한 커버(124)를 더 포함할 수 있다. 그리고, 커버(124)의 일측에는 지면과 접촉되는 접지선이 더 구비되어 안전성을 확보하는 것이 바람직하다. In addition, the heating unit 120 is provided on both sides of the asbestos cloth 121, and is provided on a pair of fixing brackets 123 fixed to the outer surface of the drum 101 and an upper end of the fixing bracket 123 to provide a heating wire. A cover 124 for preventing the 122 and the asbestos cloth 121 from being exposed to the outside may be further included. And, it is preferable that one side of the cover 124 is further provided with a ground wire in contact with the ground to ensure safety.

한편, 가열선(122)는 전력을 인가받아 열에너지는 방출하는 코일선(122-1)과 코일선(122-1)의 외부를 감싸는 피복(122-2)을 포함한다.On the other hand, the heating wire 122 includes a coil wire 122-1 for receiving electric power and emitting thermal energy, and a sheath 122-2 surrounding the outside of the coil wire 122-1.

가열부(120)는 전자유도 가열방식(Induction heating)을 사용하여 코일선(122-1)에 자기장을 발생시켜 드럼(101)을 가열하는 방식에 해당할 수 있으며, 이에 한정하지 않는다. 가열부(120)는 4개가 1개 조로 배치될 수 있다.The heating unit 120 may correspond to a method of heating the drum 101 by generating a magnetic field in the coil wire 122-1 using induction heating, but is not limited thereto. Four heating units 120 may be arranged in one set.

그리고 열분해기(100)는 연속적으로 적어도 2개 이상 설치되며, 본 발명은 3개의 열분해기(100)가 형성된 것을 실시예로 하고, 설치되는 개수를 한정하지 않는다. 각각의 열분해기(100)는 상호 연결된다. 열분해기(100)를 다수개 구비하면, 폐합성수지를 연속적으로 공급할 수 있고, 각각의 열분해기(100)에서 폐합성수지가 열분해될 수 있기 때문에 유증기의 추출량을 향상시킬 수 있다.In addition, at least two or more thermal decomposers 100 are installed in succession, and the present invention assumes that three thermal decomposers 100 are formed as an embodiment, and the number of installed thermal decomposers is not limited. Each pyrolyzer 100 is interconnected. If a plurality of thermal decomposers 100 are provided, the waste synthetic resin can be continuously supplied, and since the waste synthetic resin can be thermally decomposed in each thermal decomposer 100, the extraction amount of oil vapor can be improved.

즉, 첫번재 열분해기(100)로 폐합성수지가 투입되어 1차로 폐합성수지를 녹이면서 유증기를 추출한다. 이후, 이웃한 다른 열분해기(100)로 1차로 유증기가 추출된 폐합성수지를 전달한다. 열분해기(100)가 다수개 형성되면 이와 같은 과정이 반복되며 유증기를 추출한다. 다수의 열분해기(100) 중 첫번째 열분해기(100)에서 폐합성수지가 열분해될 때, 폐합성수지에 포함된 수분이 제거된 후 열분해기(100)의 내부가 일정온도로 승온되면서 폐합성수지가 액화되어 유증기가 추출된다. That is, the waste synthetic resin is introduced into the first thermal decomposer 100 to first melt the waste synthetic resin and extract oil vapor. Thereafter, the waste synthetic resin from which oil vapor is first extracted is transferred to another neighboring thermal decomposer (100). When a plurality of thermal decomposers 100 are formed, this process is repeated to extract oil vapor. When the waste synthetic resin is pyrolyzed in the first thermal decomposer 100 of the plurality of pyrolyzers 100, after the moisture contained in the waste synthetic resin is removed, the inside of the pyrolyzer 100 is heated to a certain temperature and the waste synthetic resin is liquefied. The oil vapor is extracted.

두번째 열분해기(100)로 전달된 액화된 폐합성수지는 수분이 제거되어있기 때문에 두번째열분해기(100)를 통과하면서 유증기만 추출될 수 있다. 여기서 각각의 열분해기(100)의 가열온도를 다르게 설정하면, 녹는점이 다른 종류로 혼합된 폐합성수지를 모두 액화시켜 유증기를 추출해낼 수 있다.Since moisture is removed from the liquefied waste synthetic resin delivered to the second pyrolyzer 100, only oil vapor can be extracted while passing through the second pyrolyzer 100. Here, if the heating temperature of each thermal decomposer 100 is set differently, oil vapor can be extracted by liquefying all the waste synthetic resins mixed with different melting points.

응축기(200)는 각각의 열분해기(100)로부터 유증기를 전달받으며, 응축기(200) 내부를 순환하는 냉각수와 유증기가 상호 열교환되면서 고온의 유증기가 냉각되어 응축기(200)의 내부에 열분해유가 응축된다. 응축된 열분해유는 저장조(400)에 저장된다. The condenser 200 receives oil vapor from each pyrolysis unit 100, and as the cooling water and oil vapor circulating inside the condenser 200 exchange heat with each other, the high-temperature oil vapor is cooled and the pyrolysis oil is condensed inside the condenser 200. . The condensed pyrolysis oil is stored in the storage tank 400.

이때, 진공펌프(310)는 열분해기(100)에서 생성된 유증기를 응축기(200)로 이동시키기 위해 기체를 흡입한다. 진공펌프(310)는 응축기(200)와 연결되어 있으며, 응축기(200) 내부 공기를 흡입함으로 인해 열분해기(100)로부터 유증기를 흡입할 수 있다. At this time, the vacuum pump 310 sucks gas to move the oil vapor generated in the thermal cracker 100 to the condenser 200. The vacuum pump 310 is connected to the condenser 200 and can suck oil vapor from the pyrolysis decomposer 100 by sucking air inside the condenser 200 .

응축기(200)의 내부에어 열분해유로 응축되지 못한 유증기는 응축기(200)와 진공펌프(310) 사이에 구비된 냉각탑(320)을 통과하면서 2차로 열교환이 이루어지며 열분해유가 응축된다. 냉각탑(320)에서 응축된 열분해유는 저장조(400)로 이동하여 저장된다.Oil vapor not condensed into the pyrolysis oil from the air inside the condenser 200 is secondarily heat exchanged while passing through the cooling tower 320 provided between the condenser 200 and the vacuum pump 310, and the pyrolysis oil is condensed. The pyrolysis oil condensed in the cooling tower 320 is moved to the storage tank 400 and stored.

냉각탑(320)에서 액화되지 못한 열분해유는 냉각탑(320)과 진공펌프(310) 사이에 구비된 서브탱크(330)로 유입된다. 유증기는 서브탱크(330)의 중공된 내부공간, 바람직하게는 서프탱크(330)의 하측으로 토출되면서 서브탱크(330) 내부공간에 잔류하는 유증기와 혼합 및 응집되면서 열분해유가 소량 응축된다. 응축된 열분해유는 저장조(400)로 이동한다. The pyrolysis oil that is not liquefied in the cooling tower 320 flows into the sub tank 330 provided between the cooling tower 320 and the vacuum pump 310 . The oil vapor is discharged to the hollow inner space of the sub tank 330, preferably to the lower side of the surf tank 330, and is mixed with and condensed with the oil vapor remaining in the inner space of the sub tank 330, condensing a small amount of pyrolysis oil. The condensed pyrolysis oil moves to the storage tank 400.

진공펌프(310)를 통과한 유증기는 별도로 마련된 냉각부(340)로 유입되어 일정온도 이하로 냉각된다. 이후 유증기는 수증기를 발생시키는 보일러(610)로 전달되어 보일러(610) 내부에 구비된 유체를 가열하여 증기를 발생시킨다. 이후 생성된 증기가 보일러(610)의 일측에 구비된 발전기(620)로 전달되어 발전기(620)를 구동시킨다. 발전기(620)는 증기를 이용하는 증기발전기에 해당하며, 구동에 따라 전력이 생산되어 생산된 전력을 가열부(120)로 전달한다. The oil vapor passing through the vacuum pump 310 flows into a separately provided cooling unit 340 and is cooled below a certain temperature. Thereafter, the oil vapor is transferred to the boiler 610 that generates steam to heat the fluid provided inside the boiler 610 to generate steam. The generated steam is then delivered to the generator 620 provided on one side of the boiler 610 to drive the generator 620. The generator 620 corresponds to a steam generator using steam, and power is generated according to driving and transfers the generated power to the heating unit 120 .

이때, 발전기(620)와 가열부(120) 사이에 인버터(630)를 더 구비하여 발전기(620)에서 생산된 직류를 교류로 변경한 후 가열부(120)로 공급된다. 따라서, 가열부(120)에 공급되는 전력을 시스템 내에서 생산이 가능해질 수 있어 경제적인 이점이 있다. At this time, an inverter 630 is further provided between the generator 620 and the heating unit 120 to change the direct current produced by the generator 620 to alternating current and then supplied to the heating unit 120 . Therefore, it is possible to produce power supplied to the heating unit 120 within the system, which has an economical advantage.

한편, 응축기(200)와 냉각부(340)에는 각각 냉각수(냉매)를 공급해줄 수 있는 칠러(210,341)와 연결되며, 냉각수가 순환되면서 유증기와 열교환을 진행시킬 수 있다. On the other hand, the condenser 200 and the cooling unit 340 are connected to chillers 210 and 341 capable of supplying cooling water (refrigerant), respectively, and heat exchange with oil vapor can be performed while the cooling water is circulated.

도 1 및 도 2 를 참조하면 열분해기(100)의 드럼(101) 일측에 형성되어 열분해된 폐합성수지와 유증기를 전달받는 포집부(500)가 더 구비된다. 포집부(500)는 복수의 열분해기(100) 사이에 구비되어 각각의 열분해기(100)를 연결시켜줄 수 있는 구성에 해당한다. Referring to FIGS. 1 and 2 , a collecting unit 500 formed on one side of the drum 101 of the pyrolysis machine 100 to receive pyrolyzed waste synthetic resin and oil vapor is further provided. The collecting unit 500 is provided between the plurality of thermal decomposers 100 and corresponds to a configuration capable of connecting each of the thermal decomposers 100 to each other.

포집부(500)를 보다 상세히 설명하면 포집부(500)는 드럼(101)의 내경보다 큰 내경을 갖고 상하측으로 연장된 탱크 형상으로 제작되어 내부에 열분해된 폐합성수지와 유증기가 일시적으로 수용될 수 있다. 또한, 포집부(500)가 상하측으로 연장되도록 형성되어 있기 때문에 내부에서 폐합성수지와 유증기가 상하측으로 분리될 수 있는 장점을 갖는다. 그리고, 포집부(500)의 하측에는 열분해된 폐합성수지를 이웃한 다른 열분해기(100)로 전달시키도록 폐합성수지가 배출되는 수지배출관(510)이 구비되고, 상측에는 유증기가 배출되는 증기배출관(520)이 형성된다.The collecting unit 500 is described in more detail. The collecting unit 500 has a larger inner diameter than the inner diameter of the drum 101 and is manufactured in a tank shape extending upwards and downwards so that the pyrolyzed waste synthetic resin and oil vapor can be temporarily accommodated therein. have. In addition, since the collecting unit 500 is formed to extend vertically, waste synthetic resin and oil vapor can be separated vertically. In addition, a resin discharge pipe 510 through which waste synthetic resin is discharged is provided on the lower side of the collecting unit 500 to transfer the pyrolyzed waste synthetic resin to another neighboring thermal decomposer 100, and on the upper side, a steam discharge pipe through which oil vapor is discharged ( 520) is formed.

도 1 및 도 4 를 참조하면 다수의 열분해기(100) 중 마지막 열분해기(100)로부터 열분해가 완료된 폐합성수지를 전달받아 수용하는 폐기물수용탱크(700)가 더 구비될 수 있다. 폐기물수용탱크(700)는 한 쌍의 제1 및 제2 수용탱크(710,720)를 포함한다. Referring to FIGS. 1 and 4 , a waste receiving tank 700 may be further provided to receive and receive waste synthetic resin, which is thermally decomposed, from the last thermal decomposer 100 among a plurality of thermal decomposers 100 . The waste receiving tank 700 includes a pair of first and second receiving tanks 710 and 720 .

열분해기(100)의 가동이 지속적으로 유지될 수 있도록 열분해기(100) 내부로 공기가 유입되는 것을 차단한 상태에서 폐합성수지의 배출이 이루어져야 하는데, 본 발명은 폐기물수용탱크(700)로 폐합성수지가 이송될 때 포집부(500) 내부로 공기가 유입되는 것을 차단한 상태에서 이송시킬 수 있다.The waste synthetic resin must be discharged in a state in which the inflow of air into the thermal decomposer 100 is blocked so that the operation of the thermal decomposer 100 can be continuously maintained. When the is transported, it can be transported in a state in which air is blocked from entering the collecting unit 500.

즉, 폐기물수용탱크(700)는 마지막 열분해기(100)와 연결된 포집부(500)와 연결되는 연결관(730), 연결관(730)과 연결되어 폐합성수지를 전달받아 제1 및 제2 수용탱크(710,720)로 전달하는 제1 및 제2 분기관(740,750)을 포함한다. That is, the waste receiving tank 700 is connected to the connecting pipe 730 connected to the collection unit 500 connected to the last pyrolysis machine 100 and the connecting pipe 730 to receive the waste synthetic resin and receive the first and second accommodations. Tanks 710 and 720 include first and second branch pipes 740 and 750.

그리고, 연결관(730), 제1 및 제2 분기관(740,750) 각각에는 제1 내지 제3 개폐밸브(731,741,751)가 각각 구비될 수 있다. 각각의 밸브의 개폐로 인해 연결관(730), 제1 및 제2 분기관(740,750)을 통해 액화된 폐합성수지의 이동여부를 제어할 수 있는 것이다. In addition, first to third opening/closing valves 731 , 741 , and 751 may be respectively provided in the connection pipe 730 and the first and second branch pipes 740 and 750 . The movement of the liquefied waste synthetic resin can be controlled through the connection pipe 730 and the first and second branch pipes 740 and 750 by opening and closing each valve.

이하, 도 4 를 참조하여 폐기물수용탱크(700)로 배출되는 폐합성수지의 이동 일실시예에 대해 보다 상세히 설명한다. Hereinafter, with reference to FIG. 4, an embodiment of the movement of the waste synthetic resin discharged to the waste receiving tank 700 will be described in more detail.

제1 개폐밸브(731)의 개방시 연결관(730), 제1 및 제2 분기관(740,750) 내부에 상기 폐합성수지가 채워진다. 이때, 제2 및 제3 개폐밸브(741,751)는 닫힌 상태를 유지한다. 그리고, 제1 개폐밸브(731)가 닫히면 제2 및 제3 개폐밸브(741,751) 중 어느 하나의 밸브가 먼저 개방되어 연결관(730), 제1 및 제2 분기관(740,750) 내부에 채워진 폐합성수지가 개방된 제2 및 제3 밸브(741,751)와 대응하는 제1 및 제2 수용탱크(710,720)로 이동한다.When the first on/off valve 731 is opened, the waste synthetic resin is filled inside the connection pipe 730 and the first and second branch pipes 740 and 750 . At this time, the second and third open/close valves 741 and 751 maintain a closed state. And, when the first on-off valve 731 is closed, any one of the second and third on-off valves 741 and 751 is opened first, and the lungs filled in the connection pipe 730 and the first and second branch pipes 740 and 750 are closed. The synthetic resin moves to the first and second accommodating tanks 710 and 720 corresponding to the opened second and third valves 741 and 751.

폐합성수지가 배출되면서 연결관(730), 제1 및 제2 분기관(740,750) 내부의 압력이 낮아지고, 이 상태에서 제2 및 제3 밸브(741,751)가 닫힌 후 제1 개폐밸브(731)가 개방되면 포집부(500) 내부에 수용된 폐합성수지가 다시 연결관(730), 제1 및 제2 분기관(740,750)을 채우게 된다. 상기 밸브의 동작이 반복되면서 공기의 유입 없이 마직막 열분해가 완료된 폐합성수지가 폐기물수용탱크(700)로 이동할 수 있는 것이다.As the waste synthetic resin is discharged, the pressure inside the connection pipe 730 and the first and second branch pipes 740 and 750 is lowered, and in this state, after the second and third valves 741 and 751 are closed, the first on-off valve 731 When is opened, the waste synthetic resin accommodated in the collecting unit 500 fills the connection pipe 730 and the first and second branch pipes 740 and 750 again. As the operation of the valve is repeated, the waste synthetic resin finally pyrolyzed can move to the waste receiving tank 700 without introducing air.

도 1 을 참조하면 첫번째 열분해기(100)에는 폐합성수지를 투입할 때, 열분해기(100) 내부로 공기의 유입을 차단한 상태에서 폐합성수지를 투입하기 위한 목적을 갖는 원료투입부(800)가 더 구비될 수 있다. 원료투입부(800)는 호퍼(810), 제1 및 제2 게이트밸브(820,830) 및 진공생성부(840)를 포함한다.

Waste synthetic resin is introduced into one side of the hopper 810, and the other side of the hopper 810 supplies the waste synthetic resin into the drum 101 of the pyrolysis machine 100. At this time, an accommodation space (S) in which the waste synthetic resin is accommodated is formed inside the hopper 810, and first and second gate valves 820 and 830 are provided on the upper and lower sides of the hopper 810 at a predetermined interval, respectively. , An accommodation space S is formed between the first and second gate valves 820 and 830.

진공생성부(840)는 폐합성수지가 수용공간(S)에 수용된 후 제1 및 제2 게이트밸브(820,830)가 닫히면 수용공간(S)의 내부 공기를 흡입하면서 수용공간(S) 내부를 진공상태로 만들어준다. 이후 제2 게이트밸브(830)가 개방되면 공기를 제외한 폐합성수지만 열분해기(100)로 이동될 수 있다. 이로 인해 폐합성수지의 투입시 외부공기의 유입으로 인한 폭발과 화재의 위험요인을 제거할 수 있다. When the first and second gate valves 820 and 830 are closed after the waste synthetic resin is accommodated in the accommodating space S, the vacuum generator 840 sucks the air inside the accommodating space S and vacuums the inside of the accommodating space S. makes it Thereafter, when the second gate valve 830 is opened, only the waste synthetic resin excluding air may be moved to the thermal decomposer 100 . As a result, it is possible to eliminate risk factors of explosion and fire due to inflow of external air when the waste synthetic resin is injected.

한편, 도 1 및 도 5 내지 도 6 을 참조하면 열분해기(100)의 드럼(101) 내부에는 한 쌍의 스크류(110)가 더 구비될 수 있다. 스크류(110)는 회전하면서 폐합성수지를 교반, 파쇄 및 이동시키기 위한 목적을 갖는다.Meanwhile, referring to FIGS. 1 and 5 to 6 , a pair of screws 110 may be further provided inside the drum 101 of the thermal decomposer 100 . The purpose of the screw 110 is to stir, crush, and move the waste synthetic resin while rotating.

스크류(110)의 외측에는 폐합성수지를 이동시키기 위해 스크류(110)의 측면을 따라 나선형을 그리며 연장되는 교반날개(111)가 더 형성된다. 이때, 스크류(110)는 소정간격 이격되어 한 쌍을 이루는데, 이때, 각각의 교반날개(111)는 도 5 를 기준으로 일부가 상호 겹치도록 한 쌍의 스크류(110)는 상호 평행을 이룬다. On the outside of the screw 110, stirring blades 111 extending in a spiral shape along the side of the screw 110 are further formed to move the waste synthetic resin. At this time, the screws 110 are spaced apart at a predetermined interval to form a pair. At this time, the pair of screws 110 are parallel to each other so that a portion of each stirring blade 111 overlaps with each other based on FIG. 5 .

한 쌍의 스크류(110)와 교반날개(111)의 겹침으로 인해 폐합성수지의 주된 종류인 PET(PolyEthylene Terephthalate) 플라스틱을 소정크기로 분쇄 및 교반시키면서 이동시킬 수 있다.Due to the overlapping of the pair of screws 110 and the stirring blades 111, PET (PolyEthylene Terephthalate) plastic, which is the main type of waste synthetic resin, can be pulverized into a predetermined size and moved while stirring.

도 6 의 (b)를 참조하면 교반날개(111)의 가장자리 및 앞뒤면에는 소정의 강도를 갖는 브러쉬(111-1)가 더 구비될 수 있다. 브러쉬(111-1)의 끝단은 드럼(101)의 내측면과 접촉하면서 드럼(101)의 내측면에 고착된 타르나, 분진 등의 불순물을 제거할 수 있다.
