摘　　要：国内低放废液磷酸三丁酯/煤油(TBP/煤油)热解焚烧处理设施的主要核心设备——热解炉是从国外某公司引进的,在工程系统冷调试过程发生了热解炉的搅拌桨卡死和高温气体过滤器严重堵塞的情况,导致系统不能稳定运行。经对热解炉检查,发现国外引进热解炉存在设计和制造缺陷,不能满足系统稳定运行。通过系统分析研究,国内自主设计一套磁力驱动搅拌桨转动装置和烧结金属高温气体过滤器,在后续调试过程中取得了比国外某公司原设计更好的运行效果,使得我国TBP-煤油热解处理设施顺利调试成功。The key pyrolysis incinerator of the first domestic pyrolysis incineration facility for low level spent tributyl-phosphate/odorless kerosene(TBP/OK)imported from A compary abroad could not operate in a steady situation during its cold commissioning phase,with the phenomena of blade block and high temperature air filter obstructing.It was found that the unstable operation was due to some defects of design and manufacture.Therefore we designed a set of magnetic stirring equipment and a high temperature air filter of sintered metal and obtained better operation effects than the original incinerator of A company abroad.Successful commissioning of the first domestic pyrolysis processing project for spent TBP/OK was achieved.
