摘要
ZRF15型放射性废物焚烧装置经过多年运行,烟气净化系统出现设备腐蚀、工艺废水量大等问题。针对这些问题,在ZRF25型放射性废物焚烧装置设计时对烟气净化工艺和设备进行了改进,包括:降低烟气急冷初始温度,增设高效过滤器预过滤,建立废水处理系统,改进设备材料等。根据冷、热态试车的结果,改进后的烟气净化系统能满足净化要求,并提高了设备的耐腐蚀性能,提高了系统的工艺安全性,降低了废水产生量,降低了烟气净化负荷。结果表明,设计改进成功地解决了原先的问题。
Problems including material corrosion and redundant waste water have been found in ZRF15radioactive waste incinerator after several years' operation. Improvements were made in the design of ZRF25 in terms of the technical process and mechanism of the flue gas cleaning system. The initial temperature of flue gas in quench was decreased. A pre-filter was installed before HEPA. The waste water treatment system was constructed. The material of equipment was improved. Results of cold and hot commissioning demonstrate the cleaning effect is desirable, the operation safety is improved, the equipment had better corrosion resistance,and the secondary waste is decreased.
