상술한 구성을 갖는 1차 건조부(30)의 작용에 대해 설명하면, 제1 챔버(36a)의 유입구(36a-1)를 통해 제1 챔버(36a) 내로 유입된 챠르는 제1 이송부(37a)에 의해서 유입구(36a-1)로부터 반대되는 방향으로 이송되고, 이러한 이송 과정에서 버너(35)의 가열 작용을 통해 가열된다.Referring to the operation of the primary drying unit 30 having the above-described configuration, the char flowing into the first chamber 36a through the inlet 36a-1 of the first chamber 36a is the first transfer unit 37a. ) Is conveyed in the opposite direction from the inlet (36a-1), and is heated by the heating action of the burner 35 in this conveying process.
그리고 제1 챔버(36a)를 따라 이송된 챠르는 제1 챔버(36a)와 연결되는 연결부(36c)를 통해 자유 낙하하여 제2 챔버(36b)의 내부로 유입되고, 이렇게 제2 챔버(36b)로 유입된 챠르는 제2 이송부(37b)에 의해서 제2 챔버(36b)의 배출구(36b-1) 방향으로 이송되며, 이러한 이송 과정에서 버너(35)의 가열 작용을 통해 가열된다. 그리고 이렇게 제2 챔버(36b)를 따라 이동된 챠르는 제2 챔버(36b)의 배출구(36b-1)를 통해 배출되어 후술되는 분쇄부(40)로 이송된다.The char transferred along the first chamber 36a freely falls through the connecting portion 36c connected to the first chamber 36a and flows into the second chamber 36b. Thus, the second chamber 36b Char flowed into is transferred to the discharge port 36b-1 of the second chamber 36b by the second transfer part 37b, and is heated by the heating action of the burner 35 in this transfer process. The char thus moved along the second chamber 36b is discharged through the discharge port 36b-1 of the second chamber 36b and transferred to the crushing unit 40 to be described later.
또한, 챠르가 제1 챔버(36a) 및 제2 챔버(36b)를 따라 이송되면서 열분해된 가스는 가스배출관(38)의 수직관(38a) 및 수평관(38b)을 경유하여 미도시된 오일추출설비로 방출된다.In addition, the char that is thermally decomposed while char is transported along the first chamber 36a and the second chamber 36b is extracted through the vertical pipe 38a and the horizontal pipe 38b of the gas discharge pipe 38.

그리고 막힘 방지 처리부(39)가 주기적으로 가동되고, 이에 따라 실린더 본체(39a-2)의 로드(39a-1)와 연동되는 ㄱ자형 로드(39a-3)가 가스배출관(38)의 수직관(38a)을 따라 상하로 왕복 이동되며, 이러한 ㄱ자형 로드(39a-3)의 상하 왕복 이동 시 스크래퍼(39b)가 연동되어 상하로 왕복 이동됨으로써, 수직관(38a)의 내면에 들러 붙은 고형물, 즉, 비산되어 오일과 함께 수직관(38a) 내면에 고착된 카본 입자가 긁어지는 방식으로 제거된다.Then, the anti-clogging treatment unit 39 is periodically operated, whereby the L-shaped rod 39a-3, which is interlocked with the rod 39a-1 of the cylinder body 39a-2, has a vertical pipe ( It is reciprocated up and down along 38a), and when the reciprocating movement of the L-shaped rod (39a-3), the scraper (39b) is interlocked and reciprocated up and down, so that the solid stuck to the inner surface of the vertical pipe (38a), that is In addition, the carbon particles scattered and adhered to the inner surface of the vertical pipe 38a together with the oil are removed in such a manner as to be scratched.
상기에서 살펴본 바와 같이, 본 발명은 1차 건조부(30) 즉 열분해로를 연속 가동 가능한 구조로 형성하여 전처리부(20)로부터 이송된 챠르의 휘발 성분을 효과적으로 제거할 수 있도록 한 것이다.As described above, the present invention is to form a primary drying unit 30, that is, a pyrolysis furnace in a continuously movable structure to effectively remove the volatile components of the char transferred from the pretreatment unit 20.
즉, 종래에는 챠르의 휘발 성분을 제거하는 건조부가 배취(batch, 일괄 처리) 타입의 열분해로 이므로, 투입구와 고형물 배출구를 선택적으로 폐쇄할 수 있어 열분해로 내부를 무산소 상태로 유지시키기에는 적합했으나, 본 발명의 연속식 열분해로와 비교하여 상대적으로 수율(yield, 투입 수에 대한 완성된 양품의 비율)이 낮은 동시에 고형 물질의 순도가 낮았다.That is, in the past, since the drying unit for removing volatile components of the char is a batch (batch) type pyrolysis furnace, the inlet and the solid outlet can be selectively closed, so that the pyrolysis is suitable for keeping the interior anoxic. Compared with the continuous pyrolysis furnace of the present invention, the yield (yield, ratio of finished good to charged water) was relatively low and the purity of the solid material was low.
종래의 열분해 과정에 대해 부연 설명하면, 먼저 열분해로 탱크에 챠르를 한번에 투입하고, 상기 열분해로 탱크에 열을 가하면 챠르의 휘발 성분이 분리되면서 열분해로 탱크 내에 유증기(oil mist)가 발생되는데, 이때 유증기가 전부 외부로 배출되지 못하여 열분해로 탱크 내부의 압력이 높아진 상태로 있게 된다. 이러한 상태에서, 휘발 성분이 분리된 챠르를 다음 공정으로 이동시키기 위해 열분해로 탱크를 개방하게 되면 상대적으로 온도가 낮은 외부 공기가 열분해로 탱크로 유입되면서 내부에 남아 있던 유증기가 기름으로 액화(liquefaction)되어 다시 챠르에 섞이게 됨에 따라, 챠르의 순도가 낮아지게 된다.The conventional pyrolysis process will be described in detail. First, char is first introduced into a tank by pyrolysis, and when heat is applied to the tank by pyrolysis, the volatilization component of the char is separated and oil mist is generated in the tank by pyrolysis. All of the oil vapor is not discharged to the outside, so that the pressure inside the tank is increased due to pyrolysis. In this state, when the tank is opened by pyrolysis to move the char having separated volatile components into the next process, relatively low temperature air is introduced into the tank by pyrolysis, and the remaining steam liquefies into oil. As it is mixed with the char again, the purity of the char decreases.
이에, 본 발명은 하우징(34), 버너(35), 제1 챔버(36a), 제2 챔버(36b), 제1 이송부(37a), 제2 이송부(37b), 가스배출관(38)을 포함하는 1차 건조부(30) 구성을 통해 챠르가 이동되면서 챠르의 휘발 성분 분리와 분리된 휘발 성분의 외부 배출이 동시에 또는 연속적으로 이루어지도록 하여 휘발 성분이 다시 챠르에 섞이지 않도록 함으로써, 챠르의 휘발 성분을 효과적으로 제거하여 챠르의 순도를 높이고, 이를 원료로 재생 카본블랙을 성형할 수 있도록 하여 재생 카본블랙의 품질을 보다 향상시킬 수 있도록 한 것이다.Accordingly, the present invention includes a housing 34, a burner 35, a first chamber 36a, a second chamber 36b, a first transfer part 37a, a second transfer part 37b, and a gas discharge pipe 38. As the char is moved through the configuration of the primary drying unit 30, the volatilization component of the char is prevented from being mixed with the char by allowing the volatilization of the char to be separated and the external discharge of the separated volatilized component simultaneously or continuously. It is to effectively remove the to increase the purity of the char, it is possible to form the recycled carbon black as a raw material to improve the quality of the recycled carbon black more.

Further, a buffer tank 102 for first storing the chars conveyed from the pneumatic conveying device 32 and a quantitative supply device 33 for quantitatively supplying the chars conveyed from the buffer tanks 102 by a predetermined unit amount are further provided. In this case, the first char stored in the buffer tank 102 may be sequentially supplied to the crushing unit 40 by a predetermined amount through the quantitative supply device 33.

도 6은 본 발명의 일 실시 예에 따른 폐타이어 열분해를 통한 챠르의 정제 및 재생 카본블랙 제조 시스템의 성형부에서 사용되는 핀 믹서 장치를 개념적으로 예시한 도면이다.FIG. 6 conceptually illustrates a pin mixer device used in a molding part of a purification and regeneration carbon black manufacturing system of char through pyrolysis of waste tires according to an embodiment of the present invention.
상기 핀 믹서(P)를 이용한 성형부(50)의 응집체 성형 과정을 보다 자세하게 살펴보면, 먼저 1차 건조부(30)와 분쇄부(40)를 거쳐 미세하게 분쇄된 재생 카본블랙이 핀 믹서(P)의 일측에 마련된 공급부(P1)를 통해 공급되는데, 상기와 같이 공급된 재생 카본블랙은 구동 축(P2)에 연결되어 고속으로 회전되는 핀(P3)에 의해 핀 믹서(P)의 길이 방향으로 이동되고, 이와 동시에 공급된 재생 카본블랙에 물이 연속적으로 분무된다. 이때, 상기 핀(P3)의 외측 단부가 핀 믹서 몸체(P4)의 내주면에 형성된 고무벽과 마찰을 일으키게 되고, 이에 따라 공급된 재생 카본블랙이 강하게 비벼지면서 뭉치게 되어 구형과 같은 응집체가 된 다음, 배출부(P5)를 통해 외부로 배출되는 것이다. 또한, 상기 바인더로 쓰이는 물은 성형되는 재생 카본블랙에 불순물을 최소화 하기 위해 일반 용수가 아니라 정수된 깨끗한 물을 사용하는 것이 바람직하다.Looking at the aggregate forming process of the molding unit 50 using the pin mixer P in more detail, first, the finely regenerated carbon black finely pulverized through the primary drying unit 30 and the grinding unit 40 is a pin mixer (P). It is supplied through the supply unit (P1) provided on one side of the, the regenerated carbon black supplied as described above is connected to the drive shaft (P2) in the longitudinal direction of the pin mixer (P) by the pin (P3) is rotated at high speed Water is continuously sprayed onto the regenerated carbon black which is transferred and simultaneously supplied. At this time, the outer end of the pin (P3) causes friction with the rubber wall formed on the inner circumferential surface of the pin mixer body (P4), so that the supplied recycled carbon black is strongly rubbed and agglomerated into a spherical aggregate such as , Is discharged to the outside through the discharge unit (P5). In addition, it is preferable to use purified water instead of general water in order to minimize impurities in the recycled carbon black to be formed as water used as the binder.
상기 핀 믹서(P)에 공급되는 재생 카본블랙은 수분 함량이 5% 미만인 것이 바람직하며, 특히 1% 미만인 것이 바람직하다. 이는 재생 카본블랙의 성형 과정에서 수분 함량을 용이하게 조절할 수 있도록 하기 위한 것이다.The regenerated carbon black supplied to the pin mixer (P) preferably has a moisture content of less than 5%, particularly preferably less than 1%. This is to make it easy to control the moisture content in the molding process of the regenerated carbon black.
또한, 상기 핀 믹서(P)를 통해 성형된 응집체는 수분 함량이 30% 내지 50% 인 것이 바람직하다. 즉, 수분 함량에 따라 응집체의 경도와 사이즈가 달라지게 되는데, 상기 응집체의 수분 함량이 30% 미만인 경우 성형되는 응집체의 경도가 너무 높고 사이즈가 작아지게 되어 사용성이 떨어지게 되며, 이와 반대로 상기 응집체의 수분 함량이 50%를 초과할 경우 응집체의 경도가 너무 낮아 이동 시 쉽게 물러지면서 구 형태를 유지하기 어렵게 되고 사이즈가 커져 역시 사용성이 떨어지게 되는 문제가 발생된다.In addition, the aggregate formed through the pin mixer (P) is preferably a water content of 30% to 50%. That is, the hardness and size of the aggregates vary depending on the moisture content. When the moisture content of the aggregates is less than 30%, the hardness of the aggregates is too high and the size decreases so that the usability decreases. If the content exceeds 50%, the hardness of the aggregate is too low to easily retire when moving, making it difficult to maintain a spherical shape, and the size also increases the problem of poor usability.
상기 구동 축(P2)의 회전 속도는 500rpm 내지 2,000rpm 인 것이 바람직하다. 상기 구동 축(P2)의 회전 속도가 500rpm 미만이거나 2,000rpm을 초과할 경우, 구형으로 응집된 재생 카본블랙이 기설정된 사이즈보다 너무 크거나 작아지게 되어 사용할 수 없게 되는 문제점이 발생되며, 심한 경우 재생 카본블랙이 펠렛화 되지 않아 재생 카본블랙으로 성형되지 못하는 문제가 생기게 된다.The rotation speed of the drive shaft P2 is preferably 500 rpm to 2,000 rpm. If the rotational speed of the drive shaft (P2) is less than 500rpm or more than 2,000rpm, there is a problem that the spherical aggregated recycled carbon black becomes too large or smaller than the predetermined size and becomes unusable. There is a problem that the carbon black is not pelletized and cannot be molded into recycled carbon black.
