Description
본 발명은 폐합성수지를 열 분해하여 석유로 재활용하도록 하는 방법과 장치에 관한 것으로, 특히 열분해 공법 중에 용융된 폐합성수지를 순환관으로 순환되도록 함으로써, 폐합성수지의 가열 면적을 극대화하여, 폐합성수지의 열분해 효율을보다 향상시킬 수 있을 뿐만 아니라, 열분해 시간을 단축할 수 있기 때문에, 보다 많은 양의 폐합성수지를 처리하여 재활용할 수 있도록 한 폐합성수지의 열분해 공법 및 그에 따른 장치에 관한 것이다.The present invention relates to a method and apparatus for thermally decomposing waste synthetic resins and recycling them into petroleum, and in particular, by circulating molten waste synthetic resins in a circulation pipe during the pyrolysis method, maximizing the heating area of the waste synthetic resins to thermally decompose the waste synthetic resins. The present invention relates to a pyrolysis method of a waste synthetic resin and a device therefor, which can not only improve efficiency but also shorten the pyrolysis time, thereby allowing a larger amount of waste synthetic resin to be processed and recycled.
일반적으로 합성수지는, 주로 비닐과 플라스틱, 스티로폼 등의 종류 별로 제조되어, 각종의 생활용품이나 기구 등의 다양한 품목을 제조, 제작하는 주요한 원료로 사용되고 있다.In general, synthetic resins are mainly produced by vinyl, plastic, styrofoam, etc., and are used as main raw materials for manufacturing and manufacturing various items such as various household goods and appliances.
이러한 합성수지는 이미 현대인의 생활에 중요하고 유익한 제조 원료로 사용되고 있지만, 합성수지 제품을 사용 후에 폐기 처분될 경우에는, 합성 수지의 특성상, 분해기간이 장시간 소요(100년∼500년)되기 때문에, 심각한 환경오염을 유발하는 요인이 되었다.This synthetic resin is already used as an important and beneficial raw material for modern people's life. However, when the synthetic resin product is disposed of after use, it takes a long time (100 to 500 years) to decompose due to the nature of the synthetic resin. It became a factor causing pollution.
상기한 용도 폐기된 폐합성수지를 그대로 방치하거나 매립할 경우에, 수질이나 토질을 훼손시키게 되고, 폐합성수지를 소각할 경우에는, 소각 시 발생하는 각종 유해 가스로 인해, 대기 오염을 유발하는 실정이었다.When the waste synthetic resins used as described above are left untreated or landfilled, water quality and soil quality are damaged, and when the waste synthetic resins are incinerated, various pollution gases generated during incineration cause air pollution.
또한, 원유 등의 에너지 소비가 급증하게 되고, 주요 에너지원인 원유가 점차 고갈되어, 원료 부족의 어려움을 겪는 상황에서, 심각한 환경오염의 유발하는 폐합성수지를 이용하여, 대체 에너지로 재활용할 수 있도록 한 연구와 개발이 절실하게 요구되고 있다.In addition, energy consumption, such as crude oil, is rapidly increasing, and the main energy source is gradually depleted, and in a situation where raw material shortage is difficult, the waste synthetic resin causing severe environmental pollution can be recycled as alternative energy. And development are urgently needed.
따라서, 본 출원인은 폐자원을 활용하여 환경오염을 방지하고 대체 에너지로 재활용할 수 있도록 한 " 폐합성수지용 유화장치 " 을 발명하여, 2000년 12월 05일 출원한 바 있다.Accordingly, the present applicant has invented the "emulsifying apparatus for waste synthetic resins" to prevent environmental pollution and recycle to alternative energy by utilizing waste resources, and filed on December 05, 2000.
상기한 종래의 폐합성수지를 재활용하는 방법은, 폐비닐, 폐플라스틱, 폐스티로폼, 또는 폐유 등을 전처리 공정(파쇄, 선별, 압출 등)과, 폐합성수지를 유화 장치의 호퍼로 이송하여 용융하는 이송 및 용융공정과, 용융된 폐합성수지를 저분자로 변화시키고 혼합기체를 생성하는 용융 및 분해공정과, 가스와 경질유, 중질유를 분리하는 분리공정을 거쳐, 폐합성수지를 연료유로 재활용하도록 하였다.The conventional method for recycling the waste synthetic resin is a conveying process for transporting waste vinyl, waste plastic, waste styrofoam, or waste oil to a pretreatment process (crushing, screening, extrusion, etc.) and transporting the waste synthetic resin to the hopper of the emulsifying apparatus for melting. And a melting process, a melting and decomposition process of changing the molten waste synthetic resin to low molecular weight and generating a mixed gas, and a separation process of separating gas, light oil and heavy oil, to recycle the waste synthetic resin as fuel oil.
그러나, 상기한 종래의 폐합성수지를 재활용하는 방법은, 폐합성수지를 용해, 용융하는 공정에서, 유화 장치의 호퍼를 가열하는 방법이 국부적인 가열방법(탱크 표면가열)으로, 호퍼 내의 폐합성수지가 전체적으로 균일하게 가열되지 못하여, 열분해 효율이 현저하게 떨어지는 문제점이 발생하였다.However, the conventional method for recycling the waste synthetic resin is a method of heating the hopper of the emulsifying device in a step of dissolving and melting the waste synthetic resin, and a local heating method (tank surface heating). Since it was not heated uniformly, there was a problem that the thermal decomposition efficiency was significantly lowered.
또한, 폐합성수지를 가열하여 열분해 되도록 하는 용융, 분해 공정의 시간이 비교적 장시간을 요하기 때문에, 다량의 폐합성수지를 신속하게 열 분해시키지 못하였으며, 유화 장치를 가열하는 히터의 가동 연료의 낭비와 손실이 심하여 경제성이 없었다.In addition, since the time required for the melting and decomposition process of heating the waste synthetic resin to thermally decompose requires a relatively long time, a large amount of waste synthetic resin could not be thermally decomposed quickly. This was not very economical.
따라서, 상기한 문제점을 해결하기 위한 본 발명은, 폐합성수지의 재활용 과정의 열분해 공정 중에, 용융된 폐합성수지를 별도로 설치된 보일러 장치의 순환관으로 순환되도록 함으로써, 순환되는 폐합성수지의 가열 면적을 최대화하기 때문에, 폐합성수지의 열분해 효율을 보다 향상시킬 수 있을 뿐만 아니라, 열분해 과정의 시간을 단축할 수 있기 때문에, 보다 많은 양의 폐합성수지를 신속하게 처리할 수 있으며, 폐합성수지의 용융, 분해에 필요한 에너지를 절감하도록 하여 경제성을갖추는데 그 목적이 있는 것이다.Therefore, the present invention for solving the above problems, during the pyrolysis process of the recycling process of the waste synthetic resin, by allowing the molten waste synthetic resin to be circulated to the circulation pipe of the boiler apparatus installed separately, to maximize the heating area of the circulated waste synthetic resin Therefore, not only can the pyrolysis efficiency of the waste synthetic resin be more improved, but the time for the pyrolysis process can be shortened, so that a larger amount of waste synthetic resin can be processed quickly, and the energy required for melting and decomposing the waste synthetic resin Its purpose is to save economics and have economic feasibility.
