Description
본 고안은 폐합성수지의 유화 설비에 관한 것으로, 보다 상세하게는 폐합성수지를 열 분해할 때 발생하여 분해로인 용해로의 내부에 달라붙는 코크스(탄화물)를 간단한 구성의 브러시로 제거함으로써 수율이 높아질 뿐 아니라 작업성이 증대되어 상품성을 증대시킬 수 있는 폐합성수지의 유화 설비에 관한 것이다.The present invention relates to an apparatus for emulsifying a waste synthetic resin, and more particularly, to a method of removing a coke (carbide) adhering to the inside of a decomposition furnace by thermal decomposition of a waste synthetic resin, And more particularly, to a system for emulsifying a waste synthetic resin which can increase the workability and increase the merchantability.
일반적으로 고도의 산업사회로 접어들면서 생활의 편리함을 추구하기 위한 수단의 하나로 가벼우면서도 사용에 편리한 플라스틱을 포함한 합성수지의 소재로한 생필품의 사용이 늘어나고 있는 실정이다.Generally, as a means to pursue the convenience of living as it moves into a highly industrialized society, the use of daily necessities as a material of synthetic resins including lightweight and easy-to-use plastics is increasing.
이러한 합성수지를 이용한 생필품은 사용하기에는 편리하나, 폐기시 자연 생 분해가 불가능하여 심각한 환경오염을 초래하게 되는 단점을 가지고 있다.Such a synthetic resin-based commodity is convenient to use, but it has disadvantages that it is impossible to decompose natural biomass at the time of disposal, thereby causing severe environmental pollution.
따라서 폐합성수지에 의한 환경오염을 방지할 목적으로 폐기된 합성수지를 재생하여 새로운 제품으로 환원 사용하기도 하나 품질이 떨어져 소비자들의 구매욕을 충족시키는데 어려움이 있어 주로 소각처리 하고 있는 실정이며, 소각처리할 경우, 소각 과정에서 발생하는 연소가스에 의한 대기중의 공기 오염으로 심각한 환경오염이 발생된다.Therefore, in order to prevent environmental pollution caused by waste synthetic resin, recycled waste synthetic resin is recycled and used as a new product. However, it is difficult to meet consumers' desire because quality deteriorates. Therefore, incineration treatment is mainly performed, Severe environmental pollution occurs due to the air pollution in the atmosphere due to the combustion gas generated in the incineration process.
상기와 같은 문제점을 해결하기 위하여 폐합성수지를 재생유(휘발유, 경유)로 환원시키기에 이르렀다.In order to solve the above-mentioned problems, the waste synthetic resin has been reduced to regenerated oil (gasoline, light oil).
폐합성수지(PE: Polyethylene, PP: Polypropylene, PET: Polyethylene Terephthalate 등 이외에 ABS)를 유료화시키는 유화설비는 최화제를 사용하는 촉매방식과 최화제를 사용하지 않는 무촉매방식이 있다.Emulsification equipment that charges waste synthetic resin (PE: Polyethylene, PP: Polypropylene, PET: Polyethylene Terephthalate and so on) has a catalyst system using the best catalyst and a no catalyst system using the best catalyst.
상기한 폐합성수지를 가지고 유화설비를 이용하여 폐합성수지 재생유(휘발유, 경유)로 환원시킬 때에는 먼저, 수거된 폐합성수지를 깨끗하게 세척한다.When the waste synthetic resin is reduced to waste synthetic resin recycle oil (gasoline, light oil) using the emulsification equipment, the collected waste synthetic resin is cleaned first.
세척된 폐합성수지를 분쇄기를 이용하여 소정 크기의 입자(3㎝∼4㎝)로 분쇄한 후, 분쇄된 폐 플라스틱을 호퍼에 부어 이송 스크류를 이용하여 분해로인 용해로 투입시키게 되며 이송 스크류에 의해 폐합성수지가 탱크에 적정량 채워지면 가열버너를 가동시켜 용해로를 가열하게 된다.The washed waste synthetic resin is pulverized into particles of a predetermined size (3 cm to 4 cm) using a pulverizer, the pulverized waste plastic is poured into a hopper, and the pulverized plastic is fed into the pulverizing furnace using a conveying screw. When the synthetic resin is filled in the tank in an appropriate amount, the heating burner is operated to heat the melting furnace.
가열버너에 의해 가열되는 용해로 내의 폐합성수지는 열에 의해 용해되어 기체화되는데 기체화가 원활하게 이루어질 수 있도록 용해로 내부로 설치된 스크류 믹서에 의해 교반된다.The waste synthetic resin in the melting furnace heated by the heating burner is dissolved by heat and gasified, and stirred by a screw mixer installed inside the melting furnace so that gasification can be smoothly performed.
이때 폐합성수지 용해는 무촉매방식에서는 보통 800℃로 가열하게 되고, 촉매 방식에서는 약500℃로 가열하게 된다.In this case, the dissolution of the waste synthetic resin is heated to 800 ° C in the non-catalytic system and heated to about 500 ° C in the catalytic system.
상기와 같이 열분해된 기체는 열교환기를 거치면서 액화상태로 변하여 중간 제품인 혼합유가 생산되고 생산된 혼합유는 탱크로 비축되며, 비축된 혼합유는 사용할 수 있게 증류탑에서 휘발유와 경유로 분리하게 되는 것이다.The gas pyrolyzed as described above is converted into a liquefied state through the heat exchanger to produce a mixed oil as an intermediate product. The produced mixed oil is stored in the tank, and the reserved mixed oil is separated into gasoline and light oil in the distillation tower.
그러나 상기와 같은 종래 기술에 따른 유화설비의 분해로인 용해로에 있어서 일정 시간이 지나면 폐합성수지를 열 분해할 때 발생한 코크스(탄화물)가 용해로 내부에 달라붙는다.However, the coke (carbide) generated when the waste synthetic resin is thermally decomposed adheres to the inside of the melting furnace after a certain period of time in the furnace melting furnace according to the prior art as described above.
따라서 일정 시간 작업 후 장시간에 걸쳐 용해로를 식힌 다음 수작업으로 용해로 내부에 달라붙은 코크스를 제거하는 작업을 수행함에 따라 열전달이 저하되어 수율이 낮을 뿐만 아니라 작업성이 저하되는 문제점을 내포하고 있었다.Therefore, after the melting furnace has been cooled for a long time after the operation for a predetermined time, the coke which has adhered to the inside of the melting furnace is removed manually, which lowers the heat transfer and lowers the yield and lowers the workability.
따라서 본 고안은 상기와 같은 종래 기술에 따른 문제점을 해결하고자 창안한 것으로, 본 고안의 목적은 폐합성수지를 열 분해할 때 발생하여 분해로인 용해로의 내부에 달라붙는 코크스를 간단한 구성의 브러시로 제거함으로써 수율이 높아질뿐 아니라 작업성이 증대되어 상품성을 증대시킬 수 있는 폐합성수지의 유화 설비를 제공하는 데 있다.Accordingly, the present invention has been made to solve the above-mentioned problems in the prior art. The object of the present invention is to provide a coke oven which is formed by thermally decomposing waste synthetic resin, Thereby increasing the yield and increasing the workability of the waste synthetic resin.
이러한 상기 목적은 본 고안에 의해 달성되며, 본 고안의 일면에 따라, 폐합성수지가 투입되는 호퍼를 구비한 투입수단과, 투입된 폐합성수지가 열분해하는 용해로와, 이 용해로를 가열하는 가열수단과, 상기 용해로에서 기체화 및 액체로 된 혼합유를 정제하는 정유 수단, 및 상기 용해로의 슬러지를 배출하는 배출수단으로 구성되는 폐합성수지의 유화 설비에 있어서, 상기 용해로는 상부 중심에 장착되는 모터와, 상기 모터에 일단부가 장착되고 타단부는 상기 용해로의 내부 저면 중심에 장착된 지지체에 회전 가능하게 장착되는 코크스 제거 브러시가 장착된다.According to another aspect of the present invention, there is provided a method of manufacturing a waste plastic recycling system, comprising the steps of: introducing means including a hopper into which waste synthetic resin is charged; a melting furnace in which the charged waste synthetic resin is pyrolyzed; A refining means for refining the mixed oil made into gasified and liquid in the melting furnace, and a discharging means for discharging the sludge of the melting furnace, wherein the melting furnace has a motor mounted at the upper center thereof, And the other end is mounted with a coke removal brush which is rotatably mounted on a support mounted at the center of the inner bottom surface of the melting furnace.
이때 상기 코크스 제거 브러시는 상기 용해로의 상부에서 하부의 내벽을 따라 근접하게 위치하는 길다란 바 형상이며 이 바의 외측에는 다수의 금속재인 브러시 모(털)가 형성되는 것을 특징으로 한다.At this time, the coke removing brush is shaped like an elongated bar located close to the inner wall of the lower part of the melting furnace, and a plurality of bristles are formed on the outer side of the bar.
본 고안은 상기와 같은 구성에 따라, 폐합성수지를 열 분해할 때 발생하여 분해로인 용해로의 내부에 달라붙는 코크스를 간단한 구성의 브러시로 제거함으로써 수율이 높아질 뿐 아니라 작업성이 증대되어 상품성을 증대시킬 수 있는 효과가 발생한다.According to the present invention, according to the above-described configuration, since the coke which sticks to the inside of the melting furnace which is generated when the waste synthetic resin is thermally decomposed is removed with a brush having a simple structure, the yield is increased and workability is increased, Effect can be generated.
