摘要: 为研究陶瓷膜在火电厂烟气水分及余热回收应用中的动态性能,在河北某330 MW燃煤电站采用40根微滤膜制作陶瓷膜组件,搭建中试装置,研究烟气流量和冷却水入口温度对水分和热量回收性能、潜热和显热释放情况的影响规律。研究结果表明,烟气流量为9 715 m3/h、冷却水入口温度为18.7 ℃时,膜组件的回收水量和热量分别可以达到43.65 kg/(m2·h)和106.31 MJ/(m2·h)。膜组件在真实的工业生产环境中展现出了良好的回收性能和极好的工业化应用潜力。

Abstract: In this paper, in order to study the dynamic performance of ceramic membrane in the applications of flue gas moisture and waste heat recovery in coal-fired power plants, a pilot apparatus was built in a 330 MW coal-fired power station in Hebei Province, in which the ceramic membrane module was integrated with 40 pipes of microfitration membrane. Then, the impacts of flue gas flow and cooling water inlet temperature on the moisture and heat recovery, as well as the latent heat and sensible heat release were studied. The study results show that with the flue gas flow at 9715 m3/h and the cooling water inlet temperature at 18.7 ℃, the moisture and heat recovered by the membrane module reach as much as 43.65 kg/(m2·h) and 106.31 MJ/(m2·h), respectively. The membrane modules have demonstrated remarkable recovery performance in actual industrial production environments and excellent potentials in industrial applications.
