도 1을 참조하면, 본 발명의 폐아크릴 처리장치는 열분해부(100), 응축부(200), 보일러(300) 및 예열부(400)를 갖는다. Referring to FIG. 1 , the waste acrylic treatment apparatus of the present invention has a pyrolysis unit 100 , a condensing unit 200 , a boiler 300 , and a preheating unit 400 .

열분해부(100)는 처리대상 폐아크릴 분쇄물을 수용하는 열분해로(110)와 열분해로(110) 내의 폐아크릴 분쇄물을 가열하는 전열히터(120)를 갖는다. 열분해로(110) 내부의 폐아크릴 분쇄물은 가열 중에 교반기(130)에 의해 교반된다. 교반기(130)는 열분해로 내의 교반익(131)과 교반익(131)을 회전 구동하는 교반모터(132)로 이루어진다.The pyrolysis unit 100 includes a pyrolysis furnace 110 for accommodating the pulverized waste acrylic to be treated and an electric heater 120 for heating the pulverized waste acrylic in the pyrolysis furnace 110 . The pulverized waste acrylic in the pyrolysis furnace 110 is stirred by the stirrer 130 during heating. The stirrer 130 includes a stirring blade 131 in the pyrolysis furnace and a stirring motor 132 for rotatingly driving the stirring blade 131 .

열분해로(110)는 측부에 폐아크릴 분쇄물이 유입되는 유입배관(111)이 연결되어 있다. 유입배관(111)으로 들어오는 폐아크릴 분쇄물은 원료탱크로부터 스크류피더(410) 혹은 컨베이어에 의해 이송되며, 예열부(400)를 거치면서 소정의 목표 예열온도로 가열된 상태로 열분해로(110)에 공급된다. The pyrolysis furnace 110 is connected to an inlet pipe 111 through which the pulverized waste acrylic is introduced to the side. The waste acrylic pulverized material entering the inlet pipe 111 is transferred from the raw material tank by a screw feeder 410 or a conveyor, and is heated to a predetermined target preheating temperature while passing through the preheating unit 400 pyrolysis furnace 110. is supplied to

열분해로(110)의 상부에는 열분해로(110) 내에서 분해된 기상 아크릴 모노머 혼합물이 배출되는 유출배관(112)이 연결되어 있으며, 하단에는 열분해과정에서 발생된 열분해잔류물이 배출되는 잔류물이송배관(113)이 연결되어 열분해잔류물을 잔류물저장공급소(340)로 이송한다. An outlet pipe 112 through which the gaseous acrylic monomer mixture decomposed in the pyrolysis furnace 110 is discharged is connected to the upper portion of the pyrolysis furnace 110, and a residue transport through which pyrolysis residues generated in the pyrolysis process are discharged at the lower end The pipe 113 is connected to transfer the pyrolysis residue to the residue storage and supply station 340 .

열분해로(110)에서 배출된 기상 아크릴 모노머 혼합물은 응축부(200)에서 열교환기를 통해 액화온도(250℃) 이하로 냉각되어 액상 상태로 기액분리기(210)에 이송된다. 기액분리기(210)에서는 액화되지 않은 미응축가스가 액상 아크릴 모노머 혼합물과 분리되어 가스이송배관(211)을 통해 가스저장공급소(330)로 이송된다. The gaseous acrylic monomer mixture discharged from the pyrolysis furnace 110 is cooled to a liquefaction temperature (250° C.) or lower through a heat exchanger in the condensing unit 200 and transferred to the gas-liquid separator 210 in a liquid state. In the gas-liquid separator 210 , the non-liquefied non-condensed gas is separated from the liquid acrylic monomer mixture and transferred to the gas storage supply station 330 through the gas transfer pipe 211 .

이송된 미응축가스는 압축과정을 통해 부피가 감소되며, 이어지는 응축과정을 통해 불순물이 제거된 상태로 가스저장공급소(330)에 저장된다.The transferred uncondensed gas is reduced in volume through a compression process, and is stored in the gas storage supply 330 in a state in which impurities are removed through a subsequent condensation process.

잔류물저장공급소(340)와 가스저장공급소(330)에 저장된 부생물은 보일러(300)의 측면과 연결되는 저장가스이송배관(331)과 저장잔류물이송배관(341)을 통해 보일러(300)에 공급되어 소각된다. The by-products stored in the residue storage supply station 340 and the gas storage supply station 330 are stored in the boiler 300 through the storage gas transport pipe 331 and the storage residue transport pipe 341 connected to the side of the boiler (300). 300) and incinerated.

부생물의 소각에서 발생되는 소각열은 예열부(400)의 전열매체를 가열하는데 사용되며, 소각잔류물은 보일러(300)에 연결되는 소각잔류물배출배관(360)과 소각가스배출배관(370)을 통해 외부로 배출된다.The incineration heat generated from the incineration of by-products is used to heat the heat transfer medium of the preheating unit 400, and the incineration residues are the incineration residue discharge pipe 360 and the incineration gas discharge pipe 370 connected to the boiler 300. discharged to the outside through

부생물의 소각은 잔류물, 가스 순으로 진행되며, 저장된 부생물이 부족할 경우 예비연료공급소(350)에 저장된 에너지원을 공급받아 보일러(300)를 가동한다. 여기서 예비연료공급소(350)에 저장된 에너지원은 화석에너지, 전기, 및 가스 등이 사용된다.Incineration of by-products proceeds in the order of residues and gases, and when the stored by-products are insufficient, the boiler 300 is operated by receiving the energy source stored in the preliminary fuel supply station 350 . Here, as the energy source stored in the preliminary fuel supply station 350, fossil energy, electricity, gas, and the like are used.

보일러(300)에서 가열된 전열매체는 전열배관(310)을 통해 폐아크릴 분쇄물이 유입되는 유입배관(111)과 연결되어 폐아크릴 분쇄물과 목표 예열온도까지 열교환을 한다.The heat transfer medium heated in the boiler 300 is connected to the inlet pipe 111 through which the waste acrylic pulverized material is introduced through the heat transfer pipe 310 to exchange heat with the waste acrylic pulverized material to a target preheating temperature.

여기서, 전열매체는 통상적으로 물이 사용되며 가스, 가열공기, 수증기, 기름, 및 비열이 높은 액상 등의 사용도 가능하다.Here, water is usually used as the heat transfer medium, and gas, heated air, water vapor, oil, and liquid with high specific heat can also be used.

이러한 폐아크릴 분쇄물의 예열과정은 열분해에 소요되는 시간을 단축하여 열분해과정에서의 에너지 소비를 절감하고 공정시간의 단축을 통한 생산성 향상이 가능하다.The preheating process of this waste acrylic pulverized product shortens the time required for pyrolysis, thereby reducing energy consumption in the pyrolysis process and improving productivity through shortening of the process time.

본 발명에서는 전열배관(310)이 유입배관(111)의 회전축선을 따라 권취되며, 전열배관(310) 내의 전열매체를 통해 폐아크릴 분쇄물을 예열한다.In the present invention, the heat transfer pipe 310 is wound along the rotation axis of the inlet pipe 111 , and the waste acrylic pulverized product is preheated through the heat transfer medium in the heat transfer pipe 310 .

이에 한정되지 않고, 도 2를 참조하면, 보일러(300)에서 가열된 전열매체는 유입배관(111)의 외측에 권취된 전열배관(310)을 따라 예열부(400)를 통과하고, 열분해로(110)로부터 응축부(200)로 전달되는 기상 아크릴 모노머 혼합물은 스크류피더(410)에 형성된 전열매체관로(411)를 통과한다. 2, the heat transfer medium heated in the boiler 300 passes through the preheating unit 400 along the heat transfer pipe 310 wound on the outside of the inlet pipe 111, and the pyrolysis furnace ( The vapor-phase acrylic monomer mixture transferred from the 110) to the condensing unit 200 passes through the heat transfer medium conduit 411 formed in the screw feeder 410 .

이와 같이, 전열매체와 기상 아크릴 모노머 혼합물이 동시에 예열부(400)를 통과하면서 폐아크릴 분쇄물의 가열에 소요되는 시간이 단축된다.In this way, while the heat transfer medium and the gaseous acrylic monomer mixture pass through the preheating unit 400 at the same time, the time required for heating the waste acrylic pulverized product is reduced.

여기서, 전열매체와 기상 아크릴 모노머 혼합물이 전열매체관로(411)와 전열배관(310)으로 변경되어 통과할 수 있지만, 기상 아크릴 모노머 혼합물의 에너지양이 전열매체와 비교하여 상대적으로 적다는 점에서 전열매체가 전열배관(310)으로 통과하여 폐아크릴 분쇄물을 예열하는 것이 더 바람직하다.Here, the heat transfer medium and the gaseous acrylic monomer mixture can be changed and passed through the heat transfer medium pipe 411 and the heat transfer pipe 310, but the energy amount of the gaseous acrylic monomer mixture is relatively small compared to the heat transfer medium. It is more preferable that the medium passes through the heat transfer pipe 310 to preheat the waste acrylic pulverized product.

도 3을 참조하면, 유입배관(111)의 내부에는 폐아크릴 분쇄물을 이송하며 회전축선을 따라 열분해로(110)에서 배출된 기상 아크릴 모노머 혼합물이 통과하는 전열매체관로(411)를 갖는 스크류피더(410)가 있다. 스크류피더(410)는 원통형 회전축과 나선형 날개로 구성되며, 축선방향 회전에 의해 폐아크릴 처리장치에 투입된 폐아크릴 분쇄물을 열분해로(110) 방향으로 이송한다.Referring to FIG. 3, a screw feeder having a heat transfer medium conduit 411 through which the gaseous acrylic monomer mixture discharged from the pyrolysis furnace 110 passes along the rotation axis while transporting the pulverized waste acrylic into the inlet pipe 111. There is (410). The screw feeder 410 is composed of a cylindrical rotating shaft and spiral blades, and transfers the waste acrylic pulverized product input to the waste acrylic treatment device by rotation in the axial direction in the direction of the pyrolysis furnace 110 .

또한, 스크류피더(410)의 날개 내부에는 기상 아크릴 모노머 혼합물이 통과할 수 있는 중공부가 형성될 수 있으며, 기상 아크릴 모노머 혼합물은 폐아크릴 분쇄물의 이송방향과 반대방향으로 이동하는 것이 바람직하다.In addition, a hollow portion through which the gaseous acrylic monomer mixture can pass may be formed inside the wing of the screw feeder 410 , and the gaseous acrylic monomer mixture preferably moves in the opposite direction to the transport direction of the waste acrylic pulverized product.

이러한 스크류피더(410)는 회전축선방향 일측에서 스크류피더(410)를 구동하는 스크류피더구동부(미도시)와 연결된다.The screw feeder 410 is connected to a screw feeder driving unit (not shown) that drives the screw feeder 410 from one side in the direction of the rotation axis.

추가적으로, 본 발명의 폐아크릴 처리장치는 정제부(500)를 더 포함한다.Additionally, the waste acrylic treatment apparatus of the present invention further includes a purification unit (500).

정제부(500)는 증류기(510), 감압증류기(511), 펌핑기(520), 정제응축기(530), 정제기액분리기(540)로 구성된다.The purification unit 500 includes a distiller 510 , a vacuum distiller 511 , a pumping unit 520 , a purification condenser 530 , and a purifier-liquid separator 540 .

기액분리기(210)에서 이송된 액상 아크릴 모노머 혼합물은 증류기(510) 내부에서 감압상태로 증류된다. 증류된 기상 아크릴 모노머는 펌핑기(520)를 통해 증류기(510)의 외부로 배출되어 정제응축기(530)로 이송한다. 정제응축기(530)에서는 이송된 기상 아크릴 모노머를 냉각하여 정제된 액상 아크릴 모노머와 미응축 정제가스를 분리한다. 분리된 미응축 정제가스는 정제기액분리기(540)에 연결된 가스이송배관(211)을 통해 가스저장공급소(330)로 이송된다. The liquid acrylic monomer mixture transferred from the gas-liquid separator 210 is distilled under reduced pressure inside the distiller 510 . The distilled gaseous acrylic monomer is discharged to the outside of the distiller 510 through the pump 520 and transferred to the purification condenser 530 . The purification condenser 530 separates the purified liquid acrylic monomer from the non-condensed purified gas by cooling the transferred gaseous acrylic monomer. The separated non-condensed purified gas is transferred to the gas storage supply station 330 through the gas transfer pipe 211 connected to the purified gas-liquid separator 540 .

본 발명의 실시예에 따른 정제부(500)는 하나가 설치되는 것으로 설명되었지만, 이에 한정하지 않고 복수개의 정제부(500)가 직렬로 연결되어 아크릴 모노머의 순도를 더욱 향상시킬 수 있다.Although it has been described that one purification unit 500 according to an embodiment of the present invention is installed, the purification unit 500 is not limited thereto, and a plurality of purification units 500 are connected in series to further improve the purity of the acrylic monomer.

도 4는 제어부(600)의 제어관련 구성을 기능적으로 도시한 블록도이다. 4 is a block diagram functionally illustrating a control-related configuration of the control unit 600 .

제어부(600)는 열분해로(110)로 유입되는 예열된 폐아크릴 분쇄물의 온도를 유입온도센서(S)를 통해 검지하며, 유입온도센서(S)로부터의 온도신호에 기초하여 스크류피더구동부의 동작을 제어한다.The control unit 600 detects the temperature of the preheated waste acrylic pulverized material flowing into the pyrolysis furnace 110 through the inlet temperature sensor (S), and the operation of the screw feeder driving unit based on the temperature signal from the inlet temperature sensor (S) to control

예를 들어, 스크류피더(410)에 의해 열분해로(110)로 투입되는 예열된 폐아크릴 분쇄물의 온도가 소정의 목표 온도 범위와 비교하여 낮을 경우 스크류피더구동부를 제어하여 스크류피더(410)의 회전을 감속시킨다.For example, when the temperature of the preheated waste acrylic pulverized product input to the pyrolysis furnace 110 by the screw feeder 410 is lower than a predetermined target temperature range, the screw feeder driving unit is controlled to rotate the screw feeder 410 . slow down

반면, 폐아크릴 분쇄물의 온도가 제어부(600)의 목표 온도 범위보다 높을 경우, 제어부(600)는 스크류피더(410)의 회전속도를 증가시킨다.On the other hand, when the temperature of the waste acrylic pulverized material is higher than the target temperature range of the controller 600 , the controller 600 increases the rotation speed of the screw feeder 410 .

이와 같은 제어부(600)의 유기적인 제어를 통해 폐아크릴 분쇄물은 예열부(400)에서 제어부(600)의 목표 온도 범위에서 예열된다.Through the organic control of the control unit 600 as described above, the pulverized waste acrylic is preheated in the target temperature range of the control unit 600 in the preheating unit 400 .
