利用等离子体高温熔融工程样机对不同种类的废物样品进行高温热解熔融处理,主要包括模拟核电厂技术废物、树脂类废物、废油吸附剂等,验证该技术对不同废物处理效果。本实验研究主要介绍了不同处理工况结果与实验过程中各系统的运行状态,研究了不同工况下系统整体运行表现与相应优化方案。等离子体高温熔融处理实验结果表明,该系统对不同种类的模拟核电厂低放废物处理能力不同,在工程应用中,均能满足设计需求,建议加强等离子体高温熔融主工艺系统前后的设计衔接,减少相互制约因素,以提高系统处理能力与处理效果。

The plasma high-temperature melting engineering prototype was used to conduct high-temperature pyrolysis and melting treatment on different kinds of waste samples,mainly including simulated nuclear power plant technical waste,resin waste and waste oil adsorbent,to verify the treatment effect of this technology on different wastes.This experimental study mainly introduces the results of different treatment conditions and the operation state of each system during the experiment,and studies the overall operation performance and corresponding optimization scheme of the system under different conditions.The experimental results of plasma high-temperature melting treatment show that the system has different treatment capabilities for different types of simulated nuclear power plant low-level waste,and can meet the design requirements in engineering applications.It is suggested to strengthen the design connection before and after the main process system of plasma high-temperature melting,reduce mutual constraints,and improve the treatment capacity and effect of the system.
