            摘要:

            利用先进的气溶胶粒径谱仪,对Laskin喷嘴喷雾性能进行了系统的试验研究。探索了发生气溶胶粒径大小、粒度分布以及浓度的诸多影响因素,主要有喷嘴结构形式、喷雾压力和溶液浓度。获得的试验数据为国家标准《高效空气过滤器性能试验方法》的修编提供了一些参考。

            Abstract:

            Performs the performance experiments of Laskin nozzle systematically by means of an aerosol particle diameter spectrometer, and discusses the affecting factors of the aerosol particle size, particle size distribution and concentration, i.e. the structure style of the nozzle, the pressure and the solution concentration. The results are helpful to revision of national standard of the Methods for testing the performance of high efficiency particulate air filter.
