摘要
样气预处理系统技术是冷干直抽法CEMS系统的核心和关键技术。在线样气预处理技术的重点和难点是样气的除湿和除尘处理。不同于传统的冷凝除湿,Nafion管除湿具有其独特的特点,是对现有除湿技术的一大补充。而以Nafion管为核心的GASS样气预处理系统,则集取样、二次过滤除尘、除酸雾除氨气、Nafion管干燥为一体,是一种创新的冷干直取法CEMS样气预处理技术,可彻底解决冷干直抽法CEMS中冷凝水和铵盐结晶问题。
Exhaust sample pretreatment system technology is the core and key technology for cold dry direct-extractive CEMS. The key point and difficulty of an on-line exhaust sample pretreatment technology lies in the dehumidification and dust removal. Unlike traditional condensation dehumidification, Nation tubing has its unique features in dehumidification and is a major supplement to current existing dehumidification technology for CEMS. GASS exhaust sample pretreatment system, with the Nafion tubing being its core, integrating probe, secondary filtration for dust removal, and acid mist removal, ammonia scrubber and Nafion tubing dryer together, is an innovative exhaust sample pretreatment technology for cold dry direct-extractive CEMS, and can entirely solve the problem of condensated water and ammonium salt crystallization occurred in such CEMS systems.
