The present invention relates to an evaluation apparatus of filter transmitting performance of an aerosol particle and, more particularly, to a series of methods that evaluates the two-dimensional distribution and transmission amount of a residual particle of which aerosol particles of fine dusts, contaminated through a protective equipment, a filter, etc., or biology spores, etc. are come out by transmitting inside thereof, and an apparatus thereof. The method and the apparatus of the present invention are suggested that the transmitting evaluation is performed by using the aerosol particle coated with fluorescence to precisely analyze structural features and performance of filter type through the residual fluorescent particle passed through the filter, and by using the same, more effective design method for the filter is derived, thus can evaluate the performance of the protective equipment or a product using the filter. The method of the present invention can more effectively evaluate space filtering performance of the filter and concentration at the same time unlike an existing method which only measures a whole amount of the filtered residual particle for an amount of the contaminated particle to evaluate the performance thereof. Also, the effective method capable of visually imaging the performance of the filter through the aerosol particle coated with fluorescence even without using an expensive particle analyzer is derived and, in particular, relates to the method which can determine an optimal design method, an operable condition, etc. through the protective performance evaluation of a purification container or the filter type being used for the military or civilian demands. |
