Description

폐합성수지로부터 재생연료유를 생산하는 방법{method of producing recycled fuel oil from waste synthetic resin}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing recycled fuel oil from waste synthetic resin,

본 발명은 환경오염을 유발하는 폐합성수지를 처리하는 기술에 관한 것으로, 특히, 용융공정에서 폭발의 위험을 제거하고 가열공정에서의 열전달 효율을 높일 수 있는 폐합성수지로부터 재생연료유를 생산하는 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology for treating waste synthetic resin causing environmental pollution, and more particularly, to a method for producing recycled fuel oil from waste synthetic resin which can eliminate the risk of explosion in a melting process and increase heat transfer efficiency in a heating process .

일반적으로 폐합성수지는 여러 가지 환경문제를 야기한다. 플라스틱 폐기물을 포함한 폐합성수지를 매립하는 경우에는 부패가 되지 않고 토양에 환원되지 않아 안정적인 지반형성을 방해하고 장기적으로는 토양오염의 원인이 된다.Generally, waste synthetic resin causes various environmental problems. When recycling plastic waste containing plastic waste, it is not corroded and is not reduced to soil, which prevents stable ground formation and causes soil pollution in the long run.

이와 같이 환경오염을 유발하는 폐합성수지의 처리 문제를 해결하기 위해, 폐합성수지를 자원으로 재활용하기 위한 에너지 재활용 기술과 원료 재활용 기술과 화학 재활용 기술 등이 활발히 연구되고 있다. Energy recycling technology, raw material recycling technology, and chemical recycling technology have been actively researched to solve the problem of waste synthetic resin which causes environmental pollution, in order to recycle waste synthetic resin as a resource.

폐합성수지의 에너지 재활용 기술은 폐합성수지의 소각하여 열에너지를 얻어내는 기술이다. 그러나, 폐합성수지를 소각하는 경우에는 인체에 해로운 발암물질인 다이옥신 등이 발생하여 인체에 직접적인 해를 줄 뿐만 아니라, 간접적으로도 토양, 물 등을 오염시켜서 2차적으로 인체에 흡수되어 심각한 문제를 야기시킨다. 그로 인해, 소각 시 발생되는 유해물질의 정화를 위한 오염방지시설을 마련해야 하는 부담은 물론 그 오염방지시설을 유지 관리해야 하는 부담도 있었다.The energy recycling technology of the waste synthetic resin is a technique of obtaining heat energy by incineration of the waste synthetic resin. However, when incinerating waste synthetic resin, dioxin, which is harmful to human body, is generated, which not only directly harms the human body but also indirectly causes contamination of soil and water, and is secondarily absorbed by the human body, . As a result, there has been a burden of maintaining a pollution prevention facility as well as a burden of preparing a pollution prevention facility for the purification of harmful substances generated during incineration.

따라서, 매립이나 소각이 아닌 플라스틱 폐기물의 재활용 문제는 시급한 현안이 되고 있는데, 폐합성수지는 에너지 재활용보다는 원료 재활용과 화학 재활용이 우선적으로 고려되고 있다.Therefore, recycling of plastic waste, not landfill or incineration, is an urgent issue. In waste plastic, priority is given to raw material recycling and chemical recycling rather than energy recycling.

폐합성수지의 원료 재활용은 폐합성수지 자체를 분류하여 합성수지 제품의 원료로 재사용한다. 폐합성수지의 원료 재활용을 위해서는 폐합성수지를 종류 별로 분류해야 하는데, 대한민국 등록특허 제10-0953559호(구획공간 가변형 안내컨테이너가 구비된 플라스틱 선별장치)나 대한민국 등록특허 제10-1262221호(시분할 제어방식 재활용 선별장치)에 게시된 바와 같은 선별 장치를 사용하여 폐합성수지를 PET, PE, PP, PS 등 원료 별로 선별하였다. 그러나, 재활용 대상 이외의 배출물들을 수작업에 의해 개별적으로 처리하는 후처리 문제나 설비를 마련하고 유지 관리해야 하는 비용적 문제를 내포하고 있을 뿐만 아니라 경제성도 낮다는 문제가 제기되고 있다.Recycled raw materials of waste synthetic resin are classified as waste synthetic resin and reused as raw materials of synthetic resin products. In order to recycle the waste synthetic resin, it is necessary to classify the waste synthetic resin according to the type thereof. For example, Korean Patent No. 10-0953559 (plastic sorting device equipped with a space-variable type guide container) and Korea Patent No. 10-1262221 Recycled sorting device) was used to sort waste synthetic resin by materials such as PET, PE, PP, and PS. However, there is a problem that not only the post-treatment problem of individually handing out emissions other than the recycling target, but also the cost problem of preparing and maintaining the facilities and the economical efficiency are also raised.

한편, 화학 재활용 기술은 폐합성수지로부터 재생연료유를 얻는 것으로, 폐합성수지를 열분해하여 발생된 유기가스를 냉각하여 오일로 전환시키는 기술이다.On the other hand, the chemical recycling technology is to obtain regenerated fuel oil from the waste synthetic resin and to convert the organic gas generated by pyrolysis of the waste synthetic resin to oil by cooling.

폐합성수지의 화학 재활용을 위해 개발된 장비로는 회분식의 배치타입과 가열 스크류를 이용한 연속식타입이 있었다.Equipment developed for chemical recycling of waste plastic was batch type and continuous type using heating screw.

회분식 배치타입은 시설비가 저렴하지만 1회씩 가동과 냉각 배출의 공정을 반복하여야 하기 때문에, 냉각 후 재가열에 요구되는 가열 에너지의 낭비가 심하고 공정의 연속성이 없어서 생산성이 낮은 문제점이 있었다.Batch type batch type has a problem in that productivity is low due to a waste of heating energy required for reheating after cooling and lack of continuity of the process because the facility cost is low but the operation and cooling discharge process must be repeated once.

가열 스크류를 이용한 연속식타입은 장비의 기술적 정교함이 요구되어 설비비가 많이 들고 처리량이 적은 관계로 사업성이 떨어지는 문제점이 있었다.The continuous type using the heating screw requires technological sophistication of the equipment, which has a problem that the facility cost is low and the throughput is low, resulting in poor business efficiency.

이러한 문제점을 해결하기 위해 용융압출식의 연속 배치타입 장치가 개발되었다. 용융압출식의 연속 배치타입 장치는 파쇄된 폐합성수지를 상온에서 그대로 열분해반응기에 투입하여 가열 용융시킨 후 압출시키는 것으로, 가열 온도까지 가열하는 데에 에너지 소모가 많아서 오일 생산의 원가를 높인다는 문제점이 있었다. 이러한 문제를 줄이기 위한 방안으로는 대한민국 등록특허 제10-0945529호(폐플라스틱의 저온 열분해 유화 시스템)에서와 같이 예열호퍼를 통해 폐합성수지를 단계적으로 가열하여 공급하는 기술이 소개된 바 있다.In order to solve this problem, a melt extrusion type continuous batch type device has been developed. In the continuous batch type apparatus of the melt extrusion type, the pulverized waste synthetic resin is put into a pyrolysis reactor at room temperature as it is, heated and melted, and extruded. Thus, there is a problem in that the energy consumption for heating to the heating temperature is high, there was. As a method for reducing such problems, there has been introduced a technique of heating the waste synthetic resin step by step through a preheating hopper, as in Korean Patent No. 10-0945529 (Low Temperature Pyrolysis Emulsification System of Waste Plastics).

또한, 폐합성수지를 가열 용융하는 도중에 발생하는 수증기의 배출이 원활하지 못하여 생산되는 유기가스 및 오일의 품질이 떨어지고, 코킹(Cocking) 현상이 발생하여 열분해반응기 내부의 용적이 감소하고, 그 코킹 현상과 함께 작업자의 온도체크 및 시간 등의 사소한 관리 미숙으로 인하여 배출 밸브에 탄화 슬러지가 쌓여 막임 현상이 자주 일어나는 문제점이 있었다.In addition, since the exhaust of steam generated during the heating and melting of the waste synthetic resin is not smooth, the quality of the produced organic gas and oil is lowered, the cocking phenomenon occurs, the volume in the pyrolysis reactor decreases, There is a problem that the carbonated sludge is piled up in the discharge valve due to the insufficient management such as the temperature check of the worker and the time and the like.

또한, 파쇄된 폐합성수지를 그대로 투입하거나 예열하여 투입하는 경우에도 가열 용융시키는 과정에서 열전달의 불균형으로 인해 용융물 내부에 공기층이 발생하였다. 종래 기술에서는 그 발생된 공기층으로 인해 열분해반응기가 폭발하는 문제가 자주 발생하였다. In addition, even when the pulverized waste synthetic resin is directly supplied or preheated, an air layer is generated inside the melt due to the uneven heat transfer during the heating and melting process. In the prior art, the pyrolysis reactor often explodes due to the generated air layer.

본 발명의 목적은 상기한 종래의 문제를 해결하기 위해 안출한 것으로, 점성의 촉매액을 파쇄된 폐합성수지와 미리 혼합하여 공급함으로써, 열분해반응기의 가열 용융 공정에서 공기층의 발생을 미연에 방지해 주는 폐합성수지로부터 재생연료유를 생산하는 방법을 제공하는 데 있다.DISCLOSURE OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a method of manufacturing a pyrolysis reactor in which a viscous catalyst liquid is preliminarily mixed with pulverized waste synthetic resin, And to provide a method for producing regenerated fuel oil from waste synthetic resin.

본 발명의 다른 목적은 열분해반응기의 용융공정에서 폭발의 위험을 제거하고 가열공정에서의 열전달 효율을 향상시켜 재생연료유의 생산속도를 높일 수 있도록 해주는 폐합성수지로부터 재생연료유를 생산하는 방법을 제공하는 데 있다.It is another object of the present invention to provide a method for producing regenerated fuel oil from waste synthetic resin that eliminates the risk of explosion in the melting process of the pyrolysis reactor and improves the heat transfer efficiency in the heating process, There is.

본 발명에 따른 폐합성수지로부터 재생연료유를 생산하는 방법의 특징은, 파쇄기에서 폐합성수지를 파쇄하여 합성수지 파쇄물을 생성하는 단계와, 혼합기에서 상기 합성수지 파쇄물을 점성의 촉매액과 혼합하여 정제용 혼합물을 생성하는 단계와, 공급호퍼에서 상기 정제용 혼합물을 열분해반응기에 투입하는 단계와, 상기 열분해반응기에서 상기 투입된 정제용 혼합물을 가열하여 용융시키는 단계와, 열분해응축기에서 상기 열분해반응기에서 발생된 유기가스를 응축시켜 재생연료유를 배출하는 단계로 이루어지는 것이다.The method for producing the regenerated fuel oil from the waste synthetic resin according to the present invention is characterized by comprising the steps of crushing the waste synthetic resin in the crusher to produce a synthetic resin crushing product, mixing the synthetic resin crush with the viscous catalyst liquid in the mixer, A step of introducing the purification mixture into a pyrolysis reactor in a feed hopper, heating and melting the introduced purification mixture in the pyrolysis reactor, and a step of heating the pyrolysis mixture in the pyrolysis condenser, And then discharging the regenerated fuel oil.

바람직하게, 상기 정제용 혼합물을 생성하는 단계는, 상기 촉매액이 상기 합성수지 파쇄물의 공극을 채우도록, 상기 혼합기의 내부에 구비되는 교반기를 사용하여 상기 합성수지 파쇄물을 상기 촉매액과 혼합하면서 교반시킬 수 있다.Preferably, the step of producing the purifying mixture may include stirring the synthetic resin crush with the catalyst liquid using a stirrer provided in the mixer so that the catalyst liquid fills the voids of the synthetic resin crush have.

바람직하게, 상기 정제용 혼합물을 생성하는 단계는, 상기 촉매액이 상기 합성수지 파쇄물의 공극을 채우도록, 상기 혼합기를 회전 또는 진동시켜서 상기 합성수지 파쇄물과 상기 촉매액을 교반시킬 수 있다.Preferably, the step of producing the purifying mixture may stir the synthetic resin crush and the catalyst liquid by rotating or vibrating the mixer so that the catalyst liquid fills the voids of the synthetic resin crush.

*바람직하게, 상기 정제용 혼합물을 생성하는 단계는, 상기 합성수지 파쇄물에 윤활유계 폐유를 상기 점성의 촉매액으로 혼합하여 상기 정제용 혼합물을 생성할 수 있다.Preferably, the step of producing the purifying mixture may comprise mixing the lubricating oil waste oil with the viscous catalyst liquid to produce the purifying mixture.

본 발명에 따른 폐합성수지로부터 재생연료유를 생산하는 방법에 의하면, 윤활유계 폐유와 같은 점성의 촉매액을 파쇄된 폐합성수지와 미리 혼합하여 열분해반응기에 공급하기 때문에 열분해반응기의 가열 용융 공정에서 용융물의 내부에 공기층이 발생하지 않는다. 그에 따라, 용융물 내부의 공기층의 팽창으로 인한 열분해반응기의 폭발 위험을 제거할 수 있다.According to the method for producing the regenerated fuel oil from the waste synthetic resin according to the present invention, since the viscous catalyst liquid such as the lubricating oil waste oil is previously mixed with the crushed waste synthetic resin and supplied to the pyrolysis reactor, An air layer does not occur inside. Thereby, the risk of explosion of the pyrolysis reactor due to the expansion of the air layer inside the melt can be eliminated.

또한, 윤활유계 폐유와 같은 점성의 촉매액을 파쇄된 폐합성수지와 혼합하고 또한 교반시켜 공급하기 때문에, 파쇄된 폐합성수지의 공극에 채워진 촉매액으로 인한 열전달 효율이 향상된다. 결국 정제용 혼합물의 용융속도가 향상되기 때문에 가열 에너지의 낭비를 줄일 수 있고 재생연료유의 생산속도도 높일 수 있는 효과가 있다.Further, since the viscous catalyst liquid such as the lubricating oil waste oil is mixed with and supplied to the crushed waste synthetic resin, the heat transfer efficiency due to the catalyst liquid filled in the pores of the crushed waste synthetic resin is improved. As a result, since the melting rate of the refining mixture is improved, it is possible to reduce the waste of heating energy and increase the production rate of the regeneration fuel oil.

또한, 본 발명에서는 윤활유계 폐유와 같은 점성의 촉매액을 파쇄된 폐합성수지와 혼합하여 열분해반응기에 공급하기 때문에, 원활한 연속 공정을 가능하게 해준다.Further, in the present invention, since a viscous catalyst liquid such as lubricating oil waste oil is mixed with pulverized waste synthetic resin and supplied to the pyrolysis reactor, a smooth continuous process is enabled.

도 1 및 2를 참조하여 폐합성수지로부터 재생연료유를 생산하는 절차를 설명한다.The procedure for producing regenerated fuel oil from waste synthetic resin will be described with reference to Figs.

본 발명에서 재생연료유를 생산하기 위한 폐합성수지로는 폴리에틸렌(PE), 폴리에틸렌테레프탈레이트, 폴리프로필렌(PP), 폴리스티렌 및 폴리염화비닐 등의 폐플라스틱류일 수 있다.The waste synthetic resin for producing the regenerated fuel oil in the present invention may be waste plastics such as polyethylene (PE), polyethylene terephthalate, polypropylene (PP), polystyrene, and polyvinyl chloride.

폐합성수지는 파쇄기에서 파쇄하여 합성수지 파쇄물을 생성한다(S100). 파쇄기를 통한 파쇄공전 이전에서는 여러 혼합된 폐기물로부터 폐합성수지를 자동으로 선별하는 장비를 더 마련할 수도 있다. The waste synthetic resin is crushed in the crusher to produce a synthetic resin crush (S100). Prior to crushing through crushers, additional equipment may be provided to automatically sort waste synthetic resins from mixed waste.

이어, 파쇄기에서 배출되는 합성수지 파쇄물을 혼합기에서 점성의 윤활유계 폐유와 혼합하여 정제용 혼합물을 생성한다(S200). 그러나, 본 발명에서는 점성의 윤활유계 폐유 이외에 대한민국 폐기물 관리법에 따른 폐연료유나 폐세정유와 같이 윤활유계 이외의 광물류 등 기름성분이 일정 비율 함유된 액체이면 사용 가능할 것이다.Next, the synthetic resin waste discharged from the crusher is mixed with the viscous lubricating oil waste oil in the mixer to produce a purification mixture (S200). However, in the present invention, it is possible to use a viscous lubricating oil waste oil as well as a liquid containing a certain amount of oil components such as waste fuel oil and waste oil refining oil according to the Korean Waste Management Law, as well as minerals other than lubricating oil.

한편, 혼합기에서 정제용 혼합물을 생성하는 공정에서는 교반기를 사용하여 혼합하는 과정에서 또는 혼합 후에 교반시킬 수도 있다. 여기서, 교반 공정은 혼합기의 내부에 구비되는 교반기를 사용하여 수행할 수도 있고, 혼합기 자체를 회전 또는 진동시켜서 수행할 수 있다.On the other hand, in the step of producing the refining mixture in the mixer, the mixture may be stirred during or after the mixing using a stirrer. Here, the stirring process may be performed using a stirrer provided inside the mixer, or by rotating or vibrating the mixer itself.

보다 상세하게, 정제용 혼합물을 생성할 시에, 점성의 윤활유계 폐유가 합성수지 파쇄물의 공극을 채우도록, 혼합기의 내부에 구비되는 교반기를 사용하여 합성수지 파쇄물을 윤활유계 폐유와 혼합하면서 교반시킬 수 있다. More specifically, when producing the refining mixture, the synthetic resin crush can be mixed with the lubricating oil waste oil while stirring using a stirrer provided inside the mixer so that the viscous lubricating oil waste oil fills the gap of the synthetic resin crush .

또는, 정제용 혼합물을 생성할 시에, 점성의 윤활유계 폐유가 합성수지 파쇄물의 공극을 채우도록, 혼합기를 회전 또는 진동시켜서 혼합되고 있는 합성수지 파쇄물과 윤활유계 폐유를 교반시킬 수 있다.Alternatively, at the time of producing the refining mixture, the mixture may be rotated or vibrated so that the viscous lubricating oil waste oil fills the voids of the synthetic resin crushing material, so that the synthetic resin crushing material and the lubricating oil waste oil being mixed can be agitated.

상기한 교반 공정을 통해 윤활유계 폐유가 합성수지 파쇄물의 공극에 채워지는 효과가 극대화되어 균일한 정제용 혼합물을 생성하게 된다.The effect of filling the voids of the synthetic resin waste with the lubricating oil waste oil is maximized through the above-described stirring process, thereby producing a uniform purification mixture.

점성의 윤활유계 폐유와 합성수지 파쇄물의 혼합비는 2:8에서 5:5로 정할 수 있다. The mixing ratio of viscous lubricating oil waste oil and synthetic resin waste can be set from 2: 8 to 5: 5.

보다 상세하게, 혼합 공정에 교반 공정을 동반하는 경우에는, 점성의 윤활유계 폐유의 혼합비율을 낮출 수 있으므로, 2:8 또는 3:7로 정하는 것이 바람직하다. More specifically, when the mixing step is accompanied by a stirring step, the blending ratio of the viscous lubricating oil waste oil can be lowered, and therefore, it is preferable to set 2: 8 or 3: 7.

또한, 혼합 공정에 교반 공정을 동반하지 않는 경우에는, 점성의 윤활유계 폐유의 혼합비율을 높여야 하므로, 4:6 또는 5:5로 정하는 것이 바람직하다. When the mixing step is not accompanied by the stirring step, the blending ratio of the viscous lubricating oil waste oil must be increased, and therefore, it is preferable to set it to 4: 6 or 5: 5.

이어, 공급호퍼에서 상기에서 생성된 정제용 혼합물을 열분해반응기에 투입한다(S300). Then, the refining mixture produced in the above-mentioned feed hopper is introduced into the pyrolysis reactor (S300).

공급호퍼는 연속식타입의 장비를 위해 자동개폐수단을 구비할 수 있으며, 열분해반응기에서 가스성분(유기가스)과 오일성분과 코크 등의 배출량에 따라 자동개폐수단의 동작을 통해 정제용 혼합물을 열분해반응기에 투입할 수 있다.The feed hopper can be equipped with an automatic opening and closing means for continuous type equipment, and it can be operated by automatic opening / closing means according to the discharge amount of gas component (organic gas), oil component and coke in the pyrolysis reactor, Can be introduced into the reactor.

이어, 열분해반응기에서는 공급호퍼를 통해 투입된 정제용 혼합물을 가열하여 용융시킨다(S400). 열분해반응기에서 정제용 혼합물을 가열하여 용융시킴에 따라, 가스성분(유기가스)과 오일성분과 코크 등이 배출될 수 있다.Next, in the pyrolysis reactor, the purification mixture introduced through the feed hopper is heated and melted (S400). As the refining mixture is heated and melted in the pyrolysis reactor, gas components (organic gas), oil components, coke and the like can be discharged.

이어, 열분해응축기에서는 열분해반응기에서 발생된 가스성분(유기가스)를 응축시켜 재생연료유를 배출한다(S500).Next, in the pyrolysis condenser, the gas component (organic gas) generated in the pyrolysis reactor is condensed to discharge the regenerated fuel oil (S500).

한편, 재생연료유를 정제하여 완제품 탱크로 배출 저장하기까지의 과정에서 열분해반응기로부터 열분해 잔사물의 배출, 더스트나 왁스나 유수의 분리, 비응축성 가스의 세정 등의 여러 공정에 대한 기술은 일반적인 사항이므로 본 발명에서는 상세한 설명을 생략한다.On the other hand, in the process of purifying the regenerated fuel oil and discharging it to the finished product tank, various techniques such as discharging pyrolysis residue from the pyrolysis reactor, separation of dust, wax and effluent, and cleaning of non- The detailed description thereof will be omitted in the present invention.

이와 같이 본 발명에서는 점성의 윤활유계 폐유를 파쇄된 폐합성수지와 미리 혼합하여 열분해반응기에 공급하기 때문에, 용융물 내부의 공기층의 팽창으로 인한 열분해반응기의 폭발 위험을 제거할 수 있을 뿐만 아니라 파쇄된 폐합성수지의 공극에 채워진 윤활유계 폐유로 인한 열전달 효율이 향상된다.As described above, since the viscous lubricating oil waste oil is mixed with the crushed waste synthetic resin in advance and supplied to the pyrolysis reactor, it is possible not only to eliminate the explosion risk of the pyrolysis reactor due to the expansion of the air layer in the melt, The efficiency of heat transfer due to the lubricating oil waste oil filled in the voids of the lubricating oil is improved.

본 발명에 따른 폐합성수지로부터 재생연료유를 생산하는 방법은 폐합성수지의 화학 재활용을 위해 개발된 장비에 모두 용이하게 적용될 수 있다. 즉, 화학 재활용을 위한 회분식의 배치타입이나 가열 스크류를 이용한 연속식타입의 장비는 물론 용융압출식의 연속 배치타입 장비에도 용이하게 적용될 수 있다.The method for producing the regenerated fuel oil from the waste synthetic resin according to the present invention can be easily applied to equipment developed for chemical recycling of waste synthetic resin. That is, the present invention can be easily applied not only to a batch type for chemical recycling, a continuous type using a heating screw, but also to a continuous batch type equipment of a melt extrusion type.
