危废处理厂废液罐区'氮封系统'和'安全泄放系统'设计探讨

摘要

随着环保行业管理日趋规范,危险废物焚烧项目在各省市大面积推广,然而与其相关的工艺设计研究缺乏,涉及系统安全方面的论述也不完善.着眼于危险废物处理厂废液罐区的"事故超压"和"有害气体挥发"等问题,提出适合于危险废物项目的工艺系统设计方案.研究内容主要包括"安全泄放装置组合式运用"和"氮封系统"等,对危废处理流程的设备安全和运行稳定等方面具有积极意义.%With the regulations of environmental industry becoming stricter recently, hazardous waste incineration projects have been popularized of in each province. However, the research about process design and relevant system safety is limited. This paper focused on the problems of overpressure accident and hazardous gas emission in the liquid waste storage zone of hazardous waste treatment plant, proposed a scheme of process system design suitable for hazardous waste disposal project. The content of this research is mainly about the combined operation of safety relief device and nitrogen seal system. This paper has positive significance for the safety and stable operation of the hazardous waste disposal process.
