采用自主研发的废塑料化学回收油化技术，设计并建设了日处理80 t废塑料资源化利用项目。该技术通过热解将废塑料转化为附加值较高的产物，实现了废塑料连续热解，攻克了废塑料热解过程中结焦和传热等技术难题，减量化显著，在处理低值塑料方面优势显著，符合国家鼓励的废物资源化利用方向。以该项目为例，介绍废塑料油化技术及项目主要系统和设备，以期为实现塑料的循环闭环提供解决方案，推动国内废塑料化学回收项目建成投产。

A 80 tons per day spent plastics recycling project has been designed and built by using the independently developed technology for chemical recovery of waste plastics and converting to fuel oil.The technology converts spent plastics into products with high added value through pyrolysis,realizing the continuous pyrolysis of spent plastics.It overcomes the technical issues such as coking and heat transfer in the pyrolysis process of spent plastics,also reduces wastes significantly and exhibits great advantages in the treatment of low-value spent plastics.This technology is in line with the direction of waste resource utilization encouraged by Chinese government.Taking this project as an example,this paper introduces the spent plastics to fuel oil technology,and the main systems and equipment of the project,in order to provide a solution for realizing the closed-loop circulation of plastics and promote the development of China's spent plastics chemical recovery industry.
