Description
본 발명은 폐수지 처리 및 재활용시스템에 관한 것으로, 더욱 상세하게는 경제적이면서 저탄소배출로 친환경적으로 폐수지로부터 재생유 및 수소를 생산할 수 있는 폐수지 처리 및 재활용시스템에 관한 것이다.The present invention relates to a waste resin treatment and recycling system, and more specifically, to a waste resin treatment and recycling system that can produce recycled oil and hydrogen from waste resin in an economical and environmentally friendly manner with low carbon emissions.
폐수지의 재활용 방법으로는 폐수지를 녹여 재성형하는 물질적 재활용과, 폐수지를 용융하여 펠릿으로 성형하여 고형연료제품(SRF)을 생산하고, 고형연료제품(SRF)을 발전이나 난방에 사용하는 열적 재활용, 그리고 폐수지를 열분해하여 기화 후 응축하여 재생유를 생성하는 화학적 재활용으로 분류된다. Recycling methods for waste resin include material recycling, which involves melting and remolding waste resin, producing solid fuel products (SRF) by melting waste resin and molding it into pellets, and thermal recycling, which is using the solid fuel product (SRF) for power generation or heating. It is classified as chemical recycling, which generates recycled oil by pyrolyzing waste resin, vaporizing it, and condensing it.
위의 폐수지 재활용 방법 중 하나인 열적 재활용의 경우 고형연료제품(SRF)이 연소시 다이옥신이 발생하여 대기환경오염에 문제가 있고, 이러한 문제점을 보완하기 위한 방법으로 폐수지로부터 재생유를 생산하는 화학적 재활용이 부각되고 있으나, 재생유만을 생산할 경우 생산비용 대비 경제성이 떨어지고, 시장의 변화(예로 수소가스 등의 수요 급증)에 적시에 대응할 수 없는 한계가 있다.In the case of thermal recycling, which is one of the above waste resin recycling methods, dioxins are generated when solid fuel products (SRF) are burned, which causes air pollution, and as a method to complement these problems, recycled oil is produced from waste resin. Chemical recycling is gaining prominence, but producing only recycled oil has low economic feasibility relative to production costs and has limitations in responding in a timely manner to changes in the market (e.g., rapid increase in demand for hydrogen gas, etc.).
