摘要: 无动力吸附技术具有活性炭消耗少、投资和运行维护成本低的优点。针对某项目污水池正常操作时仅有60%的时间在排气、在污水量最大排放时则变成40%的时间在排气的工况,采用无动力吸附工艺是比较适宜的。根据污水池中的尾气组成和流量,建立了计算方法并确定了活性炭装填量、基本尺寸、报警和联锁温度、紧急气体流量等参数,为无动力吸附装置的设计提供了依据。进一步对该过程进行分析,提出了安全建议措施:良好的气体分布装置,高效除水器,超压保护措施,电伴热防冻系统,止回阀和阻火器,维持活性炭床层内气体流动的措施和隔热措施

Abstract: Unpowered adsorption technology has the advantages of low activated carbon consumption and low investment and operation and maintenance costs. The sewage tank of a project discharges gas only 60% of the time during normal operation and 40% of the time at the maximum discharge of sewage, so it is more appropriate to adopt unpowered adsorption process. According to the tail gas composition and flow rate in sewage tank, a calculation method is established and the parameters including activated carbon loading amount, basic dimension, alarm and interlock temperature and emergency gas flow rate are determined, providing a basis for the design of unpowered adsorption system. The process is further analysed, and some safety recommendations are put forward, such as good gas distribution structure, high-efficiency dewatering device, overpressure protection measures, electric heat tracing anti-freezing system, check valve and flame arrester, measures to maintain the gas flow in activated carbon bed and insulation measures.
