固化线桶外搅拌设备调试及改进建议

在方家山核电厂水泥固化线调试过程中，进行了浓缩液、废树脂固化和废过滤器芯固定试验。试验中发现了水泥固化配方、设备设计、设备可靠性等方面存在的问题，分析了问题的原因，提出应研制出兼顾泥浆流动性、固化体性能、废物最小化和适合桶外搅拌的配方；还应从设备设计、选型和加工制作多方面优化和提升设备的可靠性；在核电厂应用前应进行充分的工程验证，提高固化线桶外搅拌工艺的可靠性。 

Commissioning and Performance Appraisal of Cement Solidification Line Intermittent Out-drum Mixing Equipment

During the commissioning of the Fangjiashan cement solidification line, the concentrate, spent resin solidification and spent filter fixation tests were conducted. The problems such as cement solidification formulations, equipment design, and equipment?reliability were found in the tests. The cause for the problems is analyzed. The formula suit?for?out-drum mixing, mud fluidity, solidification performance and waste minimization should be developed.?The equipment reliability problem should be solved from?the aspects of?equipment design, equipment selection and procurement.?The engineering validation should be performed fully before application to the nuclear power plants to improve the reliability of the out-drum mixing?process. ?
