    摘要
  • 摘要: 为研究蒸发冷凝式气溶胶多分散性对滤料透过率试验的影响程度,分别测试了从低效到高效多种滤料在不同过滤速度、不同粒数中值粒径下的透过率。通过修正计算得到典型过滤速度下的真实透过率曲线,与试验透过率对比发现:最易穿透粒径全部位于0.1~0.3 μm;试验测得最易穿透粒径呈负偏差,与修正后的数值相对误差小,最大不超过1.5%;试验气溶胶多分散性导致的透过率误差极值出现在最易穿透粒径处,呈负偏差,低效滤料相对误差较小,极值最低为2.4%,高效滤料极值最大约为10%。因此,在最易穿透粒径范围附近,蒸发冷凝式单分散试验气溶胶测出的最易穿透粒径和透过率是真实有效的。
    Abstract: To study the impact of evaporation-condensation aerosol polydispersity on the penetration measurement experiment, the penetrations of various filter materials from low to high filtration efficiency were measured at different particle count median diameter and face filtration velocity. The true penetration curves at typical filtration velocity were obtained by corrected calculation, and compared with the test penetration, which was found that all the most penetrating particle sizes were all in the range of 0.1 μm to 0.3 μm. The most penetrating particle size measured in the test had a negative deviation, and the relative error with the corrected value was very small, with a maximum value within 1.5%. The extreme value of the penetration error caused by the polydispersity of the test aerosol appeared at the position of the most easily penetrated particle size, showing a negative deviation. The relative error of the low-efficiency filter material was small, with the minimum value of 2.4%, and the maximum value of the high-efficiency filter material was about 10%. It was concluded that in the range of the most penetrating particle size, the most easily penetrated particle size and penetration measured by evaporation-condensation monodisperse aerosol were valid.
