Description

광케이블 및 폐합성수지용 열분해처리장치{Pyrolysis treatment apparatus for optical fiber cable and waste synthetic resin}Pyrolysis treatment apparatus for optical fiber cable and waste synthetic resin}

본 발명은 광케이블 및 폐합성수지용 열분해처리장치에 관한 것으로서, 더욱 상세하게는 착탈 가능한 촉매를 이용해 광케이블 및 폐합성수지의 효율적인 저온 열분해가 가능하되 반응로의 가열 및 냉각 시간을 단축할 수 있고 안전한 운전이 가능한 광케이블 및 폐합성수지용 열분해처리장치에 관한 것이다.The present invention relates to an apparatus for thermal decomposition for optical cables and waste synthetic resins, and more specifically, to enable efficient low-temperature thermal decomposition of optical cables and waste synthetic resins using removable catalysts, but can shorten heating and cooling times of the reactor and ensure safe operation. The present invention relates to a thermal decomposition treatment device for an optical cable and waste synthetic resin.

도 1은 종래기술로서 가연성 폐기물의 저온 분해 승화장치이고 그 기본 구성은 다음과 같다.1 is a low-temperature decomposition sublimation device of combustible waste as a prior art, and its basic configuration is as follows.

상기 장치는 내부에 가연성 폐기물이 수용되도록 공간부(11)가 형성된 탱크본체(10), 상기 탱크본체(10)의 벽체에 소정의 두께로 형성되는 제1 촉매부(20), 상기 탱크본체(10)의 내부 상측에 설치되는 제2 촉매부(30), 상기 탱크본체(10)에 수직 방향 및 수평 방향으로 설치되는 다수의 히팅 촉매파이프(40)를 포함하여 이루어진다.The apparatus includes a tank body 10 in which a space portion 11 is formed so that combustible waste is accommodated therein, a first catalyst portion 20 formed in a predetermined thickness on the wall of the tank body 10, and the tank body ( It comprises a second catalyst portion 30 installed on the upper side of the inside of 10), a plurality of heating catalyst pipe 40 is installed in the vertical and horizontal direction to the tank body (10).

그리고 그 작동방법은 다음과 같다.And the operation method is as follows.

비닐, 폐합성수지 등의 가연성 폐기물은 이동대차에 올려 놓고서 탱크본체(10)의 내부로 이동된다.Flammable waste materials such as vinyl and waste synthetic resin are placed on a moving cart and moved to the interior of the tank body 10.

상기 가연성 폐기물의 투입이 완료되면 공간부(11)를 밀폐시키게 되며, 히팅 촉매파이프(40)로 탱크본체(10) 내부를 가열시키게 된다.When the input of the combustible waste is completed, the space part 11 is sealed, and the inside of the tank body 10 is heated with the heating catalyst pipe 40.

이때 제1 촉매부(20) 및 제3 촉매부(30)는 히팅 촉매파이프(40)에 의해 가열되며, 이렇게 가열된 제1 촉매부(20) 및 제2 촉매부(30)에 내장된 촉매를 가열시키게 된다.At this time, the first catalyst unit 20 and the third catalyst unit 30 are heated by the heating catalyst pipe 40, and the catalyst embedded in the first catalyst unit 20 and the second catalyst unit 30 thus heated Will heat up.

그리하여 상기 가열된 촉매의 작용으로 광분해 현상이 발생하고 이는 가연성 폐기물의 분자고리를 끊어주게 되어 폐기물로부터 나프타와 물을 얻을 수 있게 되며, 나프타와 물은 승화되어 배출구(13)를 통해 배출된다.Thus, photolysis occurs due to the action of the heated catalyst, which breaks the molecular loops of combustible waste so that naphtha and water can be obtained from the waste, and naphtha and water are sublimed and discharged through the outlet 13.

그러나 상기 장치는 탱크본체 내부를 소정의 온도로 올리는데 많은 시간이 소요되는 문제가 있다.However, the device has a problem that it takes a lot of time to raise the inside of the tank body to a predetermined temperature.

또한, 제1 촉매부(20)와 같은 경우 장기간 사용에 따른 촉매의 열화는 불가피한 바 그 교환이 필요해지나 구조상 교환 작업이 곤란하다는 문제가 있다.In addition, in the case of the first catalyst unit 20, deterioration of the catalyst due to long-term use is unavoidable, and it is necessary to exchange the structure, but there is a problem in that it is difficult to exchange the structure.

또한, 가연성 폐기물의 처리가 종료된 후 화재 예방이나 작업자의 안전을 위해 탱크본체 내부 온도가 일정 온도까지 내려갈 때까지 기다려야 하는데 이에 너무 많은 시간이 소요된다는 문제가 있다.In addition, after the treatment of the combustible waste is finished, it is necessary to wait until the temperature inside the tank body decreases to a certain temperature for fire prevention or worker safety, but there is a problem that it takes too much time.

또한, 상기 장치가 예기치 않은 상황이 발생할 경우에 대한 어떠한 대비책도 마련되어 있지 않다는 것이다.In addition, the device does not have any preparedness for an unexpected situation.

상기 촉매부(200)는 다수의 세라믹촉매(205)가 내장된 촉매함(210)이 복수로 구비되어 이루어진다.
여기서, 세라믹촉매(205)는 세라믹소재로 이루어진 촉매이다.The catalyst unit 200 includes a plurality of catalyst boxes 210 in which a plurality of ceramic catalysts 205 are embedded.
Here, the ceramic catalyst 205 is a catalyst made of a ceramic material.

상기 촉매함(210)은 일측이 중심바디(110)의 내벽과 대응되는 원호 형상으로 이루어지되 내부에 구 또는 타일 형태의 세라믹촉매가 내장될 수 있는 구조로 구성된다.The catalyst box 210 is made of a structure in which one side is formed in a circular arc shape corresponding to the inner wall of the central body 110, but a spherical or tiled ceramic catalyst can be embedded therein.

상기 촉매함(210)은 중심바디(110)의 내벽으로부터 돌출 형성되되 중심바디(110)의 원주방향과 길이방향으로 이격 설치되는 다수의 지지대(250) 사이에 수납된다.The catalyst box 210 is formed to protrude from the inner wall of the center body 110 but is accommodated between a plurality of supports 250 spaced apart in the circumferential direction and the longitudinal direction of the center body 110.

상기 지지대(250)는 일단이 중심바디(110)에 고정되는 본체부(251), 본체부(251)의 타단에 고정된 원호부(253) 및 본체부(251)에 대략 수직이면서 중심바디(110)에 대략 평행하게 구비되는 평행부(255)로 이루어진다.The support 250 is a main body part 251, one end of which is fixed to the center body 110, an arc part 253 fixed to the other end of the body part 251 and the body part 251 is substantially perpendicular to the center body ( 110) is made of a parallel portion 255 provided in substantially parallel.

본체부(251), 평행부(255) 및 중심바디(110)의 사이 공간으로 촉매함(210)이 수납되고, 원호부(253)에는 촉매히터(310)가 삽입되어 고정된다.The catalyst compartment 210 is accommodated in the space between the main body part 251, the parallel part 255 and the center body 110, and the catalyst heater 310 is inserted into and fixed to the arc part 253.

즉, 상기 촉매함(210)은 중심바디(110)의 길이방향으로 이격 설치되는 지지대(250) 사이로 복수개 삽입되고, 이러한 삽입 형태를 중심바디(110)의 원주방향으로 이격 설치된 지지대(250)를 따라 반복적으로 실시한다.That is, the catalyst box 210 is inserted into a plurality between the support 250 is spaced apart in the longitudinal direction of the center body 110, the support type 250 spaced apart in the circumferential direction of the center body 110 is inserted into this type of insertion Repeat accordingly.

이와 같이, 촉매함(210)은 지지대(250) 사이에 삽입 장착됨으로써 탈착 가능한 구조가 된다.In this way, the catalyst box 210 is inserted and mounted between the supports 250 to become a detachable structure.

이는 세라믹촉매의 교환이 필요한 부분만 선택하여 교환 작업을 실시할 수 있다는 점에서 매우 유용하다.This is very useful in that it is possible to perform the exchange operation by selecting only the portion where the ceramic catalyst needs to be replaced.

상기 히팅부(300)는 도 3에 도시된 바와 같은 촉매히터(310)가 다수 개 구비됨으로써 구성된다.The heating part 300 is configured by a plurality of catalyst heaters 310 as shown in FIG. 3.

상기 촉매히터(310)는 내부에 열선(313)이 배치되고 그 외부로 페이스트(paste) 형태의 세라믹촉매(315)가 매립되며 세라믹촉매(315)의 외곽으로 보호관(317)이 구비되는 구조로 이루어진다.The catalyst heater 310 has a structure in which a heating wire 313 is disposed inside, a ceramic catalyst 315 in the form of a paste is buried outside, and a protective tube 317 is provided outside the ceramic catalyst 315. Is done.

또한, 상기 촉매히터(310)는 후면바디(130) 측으로부터 상기 중심바디(110)의 길이 방향으로 삽입되어 구비되고 도 3에 도시된 바와 같이 상기 중심바디(110)의 원주방향으로 이격 설치되어 있다.In addition, the catalyst heater 310 is provided by being inserted in the longitudinal direction of the center body 110 from the rear body 130 side and is spaced apart in the circumferential direction of the center body 110 as shown in FIG. have.

이와 같은 배치 구조는 종래의 배치 방식에 비해 반응로(100) 내부의 보다 균일한 가열이 가능해진다.This arrangement structure allows for more uniform heating inside the reactor 100 compared to the conventional arrangement method.

앞선 촉매부(200)와 히팅부(300)의 작용으로 즉, 반응로(100) 내부에 설치된 촉매히터(310)에 의한 열과 중심바디(110) 내측에 배치된 다수의 세라믹촉매(205)에 의해 반응로 내부에 장입된 고체 상태의 광케이블 및 폐합성수지는 광케이블 및 폐합성수지의 고분자 사이의 결합이 끊어져 유증기로 분해된다.Due to the action of the preceding catalyst unit 200 and the heating unit 300, that is, the heat generated by the catalyst heater 310 installed inside the reactor 100 and the plurality of ceramic catalysts 205 disposed inside the central body 110 By this, the solid state optical cable and waste synthetic resin loaded inside the reactor are broken down into bonds between the polymer of the optical cable and the waste synthetic resin and decomposed into oil vapor.

이때, 상기 반응로(100)에서 생성되는 유증기를 열분해유(熱分解油)라 한다.At this time, the vapor generated in the reaction furnace 100 is called pyrolysis oil.

상기 가열냉각부(400)는 열분해유의 생산성 향상을 위한 구성으로서, 반응로(100)의 가열을 위한 가열매체의 이동 공간을 제공하고, 또한 반응로(100)의 냉각을 위한 냉각매체의 이동 공간을 제공한다.The heating and cooling unit 400 is a configuration for improving the productivity of pyrolysis oil, providing a moving space of the heating medium for heating the reactor 100, and also moving space of a cooling medium for cooling the reactor 100 Gives

이하, 상기 가열매체 및 냉각매체를 통칭하여 "열전달매체"라 한다.Hereinafter, the heating medium and the cooling medium are collectively referred to as "heat transfer medium".

상기 가열냉각부(400)에는 가열수단 및 냉각수단이 연결되되, 상기 가열냉각부(400)는 단면상 중심바디(110)와 동심원을 이루는 원통의 가열냉각관(410) 및 중심바디(110)와 가열냉각관(410) 사이에 구비되는 다수의 격벽(430)으로 이루어진다.A heating means and a cooling means are connected to the heating and cooling part 400, and the heating and cooling part 400 is a cylindrical heating and cooling tube 410 and a central body 110 concentric with the central body 110 in cross section. It consists of a plurality of partition walls 430 provided between the heating and cooling tube 410.

가열냉각관(410)의 길이방향 일단은 플랜지(140)에 고정 결합되며 타단은 절곡부(415)가 형성되어 이 절곡부(415)가 중심바디(110)에 고정 결합된다.One end in the longitudinal direction of the heating and cooling tube 410 is fixedly coupled to the flange 140, and the other end is formed with a bent portion 415, and the bent portion 415 is fixedly coupled to the central body 110.

그리고 상기 가열냉각부(400) 내부에는 다수의 격벽(430)이 구비되어 있어 열전달매체가 중심바디(110)의 길이방향으로 유동한 후 방향을 전환하여 반대의 길이방향으로 유동하는 것을 반복할 수 있도록 구성되어 있다.In addition, a plurality of partition walls 430 are provided inside the heating and cooling unit 400, so that the heat transfer medium flows in the longitudinal direction of the central body 110, and then switches directions to flow in the opposite longitudinal direction. It is configured to.

이와 같이, 상기 중심바디(110)의 외측에 가열냉각부(400)가 위치하는바 상기 중심바디(110)와 가열냉각부(400)는 각각 내측관과 외측관의 형태로 구비됨으로써 이중관 형태로 구성된다.As described above, since the heating and cooling unit 400 is located outside the center body 110, the center body 110 and the heating and cooling unit 400 are provided in the form of an inner tube and an outer tube, respectively, to form a double tube. It is composed.

먼저, 반응로(100)를 가동하여 운전을 개시할 때는 히팅부(300)를 작동시킴과 동시에 가열냉각부(400)로 가열수단인 가열매체로서의 고온의 스팀을 유입시킨다.First, when starting the operation by operating the reactor 100, the heating unit 300 is operated and at the same time, hot steam as a heating medium, which is a heating means, is introduced into the heating and cooling unit 400.

그러면 고온의 스팀은 가열냉각부(400) 내부에 구비된 다수의 격벽(430)을 따라 유동하면서 중심바디(110)를 전체적으로 균일하게 가열하게 된다.Then, the high-temperature steam flows along the plurality of partition walls 430 provided inside the heating and cooling unit 400 to uniformly heat the center body 110 as a whole.

이처럼 금속 재질의 중심바디(110)가 고온의 스팀에 의해 가열되므로 반응로(100) 내부 온도의 상승에 필요한 가열시간을 단축할 수 있게 된다.As such, since the central body 110 made of a metal material is heated by high temperature steam, it is possible to shorten the heating time required to increase the temperature inside the reactor 100.

이때, 가열에 필요한 히팅부(300)의 전력 사용량을 고려하면 고온의 스팀으로 먼저 반응로(100)를 예열한 후 히팅부(300)를 작동시키는 것으로 변경할 수도 있다.In this case, considering the power consumption of the heating unit 300 required for heating, the heating unit 300 may be preheated first with high-temperature steam and then the heating unit 300 may be operated.

그 후, 고온의 스팀은 유동과정에서 응축되어 반응로(100)의 외부로 배출된다.Thereafter, the hot steam is condensed in the flow process and discharged to the outside of the reactor 100.

다만, 고온의 스팀에 의한 가열에는 한계가 있어 계속적인 공급은 효과적이지 못하므로 반응로(100) 내부 온도가 150℃ 정도로 올라오면 스팀 공급을 중지하고, 그 이후에는 히팅부(300)에 의한 가열만이 이루어진다.However, since there is a limit to heating by high temperature steam, continuous supply is not effective, so when the temperature inside the reactor 100 rises to about 150° C., supply of steam is stopped, and thereafter heating by the heating unit 300 Only is done.

한편, 이렇게 배출되는 응축수는 온도가 높은 상태이므로 본 발명에서는 이를 재활용하는 예열컨테이너(600)의 구성을 추가할 수 있다.On the other hand, since the discharged condensate is in a high temperature state, in the present invention, the configuration of the preheating container 600 for recycling it may be added.

즉, 예열컨테이너(600)의 내부로 고온의 응축수가 통과할 수 있도록 하고 예열컨테이너(600)의 내부에 나중에 작업할 광케이블이나 폐합성수지가 적재된 대차(A)를 투입시켜서 이들을 예열해 놓는다.That is, the condensed water of high temperature is allowed to pass into the preheating container 600 and the preloaded container 600 is loaded with an optical cable or waste synthetic resin to be processed later to preheat them.

가열냉각부(400)에 연결되는 냉각수단에 대해서는 후술한다.The cooling means connected to the heating and cooling unit 400 will be described later.

이러한 과정으로 저온 열분해처리의 전 과정에 소요되는 에너지 소비량을 줄일 수 있게 된다.Through this process, it is possible to reduce energy consumption required for the entire process of low-temperature pyrolysis.

다음으로, 상기 열분해처리과정을 통해 생성된 열분해유는 배출구(115)를 통해 메인배관(550)으로 기체 상태로 배출되는데, 이러한 열분해유를 크래킹 작용으로 다시 탄소 결합이 끊어지도록 하기 위해 메인배관(550) 상에 촉매반응기(710)를 구비한다.Next, the pyrolysis oil generated through the pyrolysis treatment process is discharged in a gaseous state to the main pipe 550 through the discharge port 115, and the main pipe ( A catalytic reactor 710 is provided on 550.

촉매반응기(710)에서 배출되는 열분해유를 액화하기 위하여 응축기(730)가 구비되고, 응축기(730)에서 액화된 열분해유를 유입시켜 물을 분리해내는 탱크(750)가 구비된다.A condenser 730 is provided to liquefy the pyrolysis oil discharged from the catalytic reactor 710, and a tank 750 for separating water by introducing the liquefied pyrolysis oil from the condenser 730 is provided.

한편, 본 장치의 운전 중에는 반응용기(100) 내부의 상황을 알 수 없으므로 경험에 의한 작업자의 주관적 판단으로 운전을 중단할 수 밖에 없는바, 이는 경제성 및 생산성 측면에서 바람직하지 못하다.On the other hand, since the situation inside the reaction vessel 100 is not known during the operation of the device, it is inevitable to stop the operation due to the subjective judgment of the operator by experience, which is not desirable in terms of economic efficiency and productivity.

이에 본 발명에서는 농도측정기(770)가 메인배관(550)을 통과하는 열분해유의 농도를 측정함으로써 본 장치의 운전 중단 시기를 정할 수 있다.Accordingly, in the present invention, the concentration measuring device 770 measures the concentration of the pyrolysis oil passing through the main pipe 550 to determine the time to stop the operation of the device.

즉, 메인배관(550)을 통과하는 열분해유의 농도는 운전 시간대별로 변화할 것이어서 그로부터 특정 그래프를 얻을 수 있고 이는 가장 효과적으로 열분해유를 생산할 수 있는 운전시간을 정할 수 있다는 의미이므로 농도측정기(770)를 통한 열분해유의 농도가 그래프의 특정 구간에 진입할 때 운전을 중단하도록 제어하는 것이다.That is, since the concentration of the pyrolysis oil passing through the main pipe 550 will change for each operation time period, a specific graph can be obtained therefrom, which means that the operation time for producing pyrolysis oil most effectively can be determined. The concentration of pyrolysis oil through is controlled to stop the operation when entering a specific section of the graph.

상기 배관부(500)는 가열냉각부(400) 내부로 유입/유출되는 스팀, 응축수, 공기 및 냉각수의 유동 통로를 제공하거나, 반응로(100) 내부로 유입되는 질소가스 및 소화제의 유동 통로를 제공하거나, 또는 열분해유의 배출 통로를 제공하기 위한 것으로서 다수의 배관을 포함하여 이루어진다.The piping part 500 provides a flow passage of steam, condensate, air and cooling water flowing into/out of the heating and cooling part 400, or a flow passage of nitrogen gas and an extinguishing agent flowing into the reactor 100. Provided, or to provide a discharge passage for pyrolysis oil, and includes a plurality of pipes.

상기 다수의 배관에는 가열매체인 스팀의 유입통로인 스팀배관(505), 스팀이 액화된 응축수의 유출통로인 응축수배관(510), 냉각매체인 공기의 유입통로인 공기유입배관(515), 냉각매체인 공기의 유출통로인 공기유출배관(520), 냉각매체인 냉각수의 유입 통로인 냉각수유입배관(525), 냉각매체인 냉각수의 유출 통로인 냉각수유출배관(530), 소화매체인 질소가스의 유입 통로인 질소가스배관(535), 소화매체인 소화제의 유입 통로인 소화제배관(540), 및 열분해유의 배출 통로인 메인배관(550)이 포함된다.The plurality of pipes include a steam pipe 505, which is an inflow passage of steam, which is a heating medium, a condensation water pipe 510 which is an outflow passage of condensate in which steam is liquefied, and an air inlet pipe 515 that is an inflow passage of air as a cooling medium, cooling The air outlet pipe 520, which is an outlet passage of air as a medium, the cooling water inlet pipe 525, which is an inflow passage of cooling water as a cooling medium, the cooling water outlet pipe 530, which is an outlet passage of cooling water as a cooling medium, and the nitrogen gas as a digestion medium. It includes a nitrogen gas pipe 535 which is an inlet passage, a fire extinguishing agent pipe 540 that is an inlet passage of the extinguishing agent as a digestion medium, and a main pipe 550 that is a discharge passage of pyrolysis oil.

또한, 후술하는 압력강하수단의 안전밸브(560)와 연결되는 안전밸브배관(565)도 포함된다.In addition, a safety valve pipe 565 connected to the safety valve 560 of the pressure drop means described later is also included.

한편, 최종 운전 종료시에는 도어(120)를 개방하더라도 작업자가 화상을 입지 않도록 또는 화재 발생의 염려가 없도록 반응로(100)의 내부 온도를 강하시킬 필요가 있다.On the other hand, at the end of the final operation, even if the door 120 is opened, it is necessary to lower the internal temperature of the reactor 100 so that the operator does not get burned or there is no fear of fire.

이에 본 발명에서는 종래의 자연 냉각방식이 너무 많은 시간이 소요되는 점을 고려하여 가열냉각부(400)에 냉각수단을 연결함으로써 이를 해결한다.Accordingly, the present invention solves this by connecting a cooling means to the heating and cooling unit 400 in consideration of the fact that the conventional natural cooling method takes too much time.

즉, 1차적으로 열전달매체로서의 공기를 송풍팬으로 가열냉각부(400)로 유입시켜 공기가 가열냉각부(400) 내부에 구비된 다수의 격벽(430)을 따라 유동하면서 중심바디(110)를 전체적으로 균일하게 냉각시키게 하고, 반응로(100)의 내부 온도가 대략 150℃ 정도로 떨어지면 2차적으로 상기 공기의 공급을 차단하면서 펌프를 이용해 열전달매체로서의 냉각수를 가열냉각부(400)로 유입시켜 반응로(100)를 냉각시킨다.That is, the air as a heat transfer medium is first introduced into the heating and cooling unit 400 by a blower fan, and the air flows along a plurality of partition walls 430 provided inside the heating and cooling unit 400, thereby causing the central body 110 to flow. Cooling the whole uniformly, when the internal temperature of the reactor 100 falls to about 150 ℃, while secondaryly blocking the supply of air, the cooling water as a heat transfer medium is introduced into the heating and cooling unit 400 by using a pump. Cool (100).

한편, 열전달매체로서의 공기를 송풍팬으로 가열냉각부(400)로 유입시킬 때는 계절적 영향으로 공기의 온도가 낮은 상태가 아닐 경우를 대비하여 공기유입배관(515)에 냉각기(517)를 추가적으로 구비할 수 있다.On the other hand, when the air as a heat transfer medium is introduced into the heating and cooling unit 400 by a blower fan, a cooler 517 is additionally provided in the air inlet pipe 515 in case the temperature of the air is not low due to seasonal influence. Can be.

반응로(100)를 냉각하는데 사용된 냉각수는 가열냉각부(400)에서 유출될 때 고온 상태가 되는바, 이를 다시 응축 냉각수단(800)을 통과시켜 저온 상태로 만든 후 다시 가열냉각부(400)로 유입시키는 과정을 반복함으로써 냉각수는 계속적으로 순환된다.The cooling water used to cool the reaction furnace 100 is in a high temperature state when it flows out of the heating and cooling unit 400, and it is again passed through the condensation cooling means 800 to make it a low temperature state, and then the heating and cooling unit 400 again. ), the cooling water is circulated continuously.

냉각 시간만을 고려하면 처음부터 냉각수를 이용한 냉각이 더 효율적일 것이나, 갑작스러운 냉각은 반응로(100)에 해머링(hammering)을 유발할 수 있으므로, 본 발명에서는 위와 같이 공기로 1차 냉각하고 냉각수로 2차 냉각함으로써 이러한 해머링을 방지할 수 있다.If only the cooling time is considered, cooling with cooling water will be more efficient from the beginning, but sudden cooling may cause hammering in the reactor 100, so in the present invention, the first cooling with air and the second with cooling water Cooling can prevent this hammering.

그리고 반응로(100)의 내부 온도가 90℃ 미만이 되면 도어(120)를 개방하고 대차(A)를 꺼내게 된다.Then, when the internal temperature of the reactor 100 is less than 90°C, the door 120 is opened and the truck A is taken out.

본 발명에서는 장치의 운전시 발생할 수 있는 비상 상황에 대처할 수 있는 각종 수단들이 구비된다.In the present invention, various means are provided to cope with emergency situations that may occur during operation of the device.

먼저, 반응로(100)의 내부압력이 비정상적으로 상승하면 이를 감지하여 내부압력을 강하시킬 수 있는 압력강하수단을 구비함으로써 장치의 안정성을 확보할 수 있다.First, when the internal pressure of the reactor 100 rises abnormally, it is possible to secure the stability of the device by providing a pressure drop means capable of detecting this and lowering the internal pressure.

상기 압력강하수단으로는 압력센서(미도시)와 안전밸브(560)를 채택한다.As the pressure dropping means, a pressure sensor (not shown) and a safety valve 560 are adopted.

압력센서는 반응로(100)의 내부압력을 감지하고 감지된 압력이 설정된 압력 이상이 되면 안전밸브(560)를 작동시켜 반응로(100) 내부의 기체를 외부로 강제적으로 배출시킴으로써 반응로(100)의 내부압력을 떨어뜨린다.The pressure sensor senses the internal pressure of the reactor 100 and when the sensed pressure exceeds a set pressure, operates the safety valve 560 to forcibly discharge the gas inside the reactor 100 to the reactor 100. ) To reduce the internal pressure.

또한, 반응로(100)의 내부는 매우 높은 온도로 가열되는 환경이기 때문에 항상 화재의 위험성이 있고 본 발명에서는 이를 위해 소화수단을 더 구비한다.In addition, since the inside of the reactor 100 is an environment heated to a very high temperature, there is always a risk of fire and in the present invention, fire extinguishing means are further provided for this purpose.

상기 소화수단으로는 온도센서(555)와 질소탱크(536)에 저장된 질소 가스나 소화제탱크(541)에 저장된 소화제를 이용한다.As the extinguishing means, a nitrogen gas stored in the temperature sensor 555 and the nitrogen tank 536 or an extinguishing agent stored in the extinguishing agent tank 541 is used.

온도센서는 반응로(100)의 내부 온도를 감지하고 감지된 온도가 설정 온도, 예를 들어 350℃ 이상이 되면 1차적으로 질소 가스를 반응로(100) 내부로 유입시켜 화재 발생을 억제하고, 그럼에도 불구하고 온도가 계속 상승하여 설정 온도, 예를 들어 450℃를 넘게 되면 반응로(100) 내부에 화재가 발생한 것으로 판단하여 2차적으로 포말형태의 소화제를 반응로(100) 내부로 유입시켜 화재를 진압하게 된다.The temperature sensor detects the internal temperature of the reactor 100 and, when the detected temperature is set temperature, for example, 350°C or higher, primarily introduces nitrogen gas into the reactor 100 to suppress the occurrence of fire, Nevertheless, if the temperature continues to rise and exceeds a set temperature, for example, 450°C, it is determined that a fire has occurred inside the reactor 100 and secondarily, a fire extinguishing agent having a foam-type extinguishing agent is introduced into the reactor 100. Will be suppressed.

본 발명의 광케이블 및 폐합성수지용 열분해처리장치를 이용한 운전 과정을 살펴보면 다음과 같다.Looking at the operation process using the thermal decomposition device for the optical cable and waste synthetic resin of the present invention is as follows.

먼저, 광케이블이나 폐합성수지가 적재된 대차(A)를 반응로(100)의 내부로 투입시킨다.First, the truck (A) loaded with an optical cable or waste synthetic resin is introduced into the reactor 100.

상기 투입이 완료되면 도어(120)를 닫고, 촉매히터(310)를 작동시킴과 동시에 가열냉각부(400)로 고온의 스팀을 유입시켜 반응로(100) 내부를 대략 250±20℃까지 가열시킨다.When the input is completed, the door 120 is closed, the catalyst heater 310 is operated, and at the same time, hot steam is introduced into the heating and cooling unit 400 to heat the inside of the reactor 100 to approximately 250±20°C. .

그리고 반응로(100) 내부가 상기의 설정 온도까지 가열된 후에는 다수의 세라믹촉매(205)의 작용으로 광케이블이나 폐합성수지의 광분해가 활발히 이루어져 기체 상태의 열분해유가 생성되며, 이 열분해유는 반응로(100)의 배출구(115)를 거쳐 반응로(100) 외부로 배출된다.In addition, after the inside of the reactor 100 is heated to the above set temperature, photolysis of an optical cable or waste synthetic resin is actively performed under the action of a plurality of ceramic catalysts 205 to generate gaseous pyrolysis oil, which is a reaction furnace. It is discharged to the outside of the reactor 100 through the discharge port 115 of the (100).

반응로(100) 외부로 배출된 열분해유는 제올라이트 합성 계열의 촉매들로 채워져 있는 촉매반응기(710)를 통과하면서 다시 탄소의 결합이 끊어지는 크래킹이 발생되고, 그 후 응축기(730)를 거치면서 액화되어 탱크(750)로 유입된다.As the pyrolysis oil discharged to the outside of the reactor 100 passes through the catalytic reactor 710 filled with catalysts of the zeolite synthesis system, cracking in which carbon bonds are broken again occurs, and then passes through the condenser 730. It is liquefied and flows into the tank 750.

상기 반응로(100) 외부로 배출된 열분해유는 유증기의 형태이므로 물이 포함되어 있는바, 탱크(750)에서는 열분해유에서 물을 분리하고 액상의 열분해유만을 다음 공정으로 진행시킨다.Since the pyrolysis oil discharged to the outside of the reactor 100 is in the form of steam, water is included. In the tank 750, water is separated from the pyrolysis oil and only the liquid pyrolysis oil proceeds to the next process.
