本文基于交叉波纹填料塔膜式除尘机理以及酸性氧化电位水的除菌特性,提出以酸性氧化电位水作为工质的环境友好型空气净化系统,研究酸性氧化电位水降膜除尘除菌的可行性以及主要影响因素。实验结果表明,在入口风速为1~6.2 m/s,布水密度为0.15 m3/h的实验条件下,除尘总效率随着入口风速的增大而提高,其效率在15.35%~43%,在相同实验条件下,入口风速越大,除菌效率越高,除菌效率在26.86%~60.6%;颗粒物分级效率随着粒径的增大而升高,在6.2 m/s入口风速条件下,1~3μm粒径范围的颗粒物净化效率为50.09%;入口颗粒物浓度、自然菌浓度对除尘、除菌效率无明显影响;酸性氧化电位水对颗粒物、微生物的净化效率具有强相关性。
