A simple method of testing fibrous filters to obtain the grade efficiency curve in the particle size range 2-22 μm is described. Dust collected by the test filter is analysed and compared with that collected by a master filter. The method has been used to measure the retention efficiency of model filters and it is shown that there is a maximum in the grade efficiency curve. The presence of this maximum is explained mechanistically. The influence of relative humidity on filter behaviour has been investigated. It is shown that the efficiency of filtration in high particle inertia systems increases with increasing relative humidity. It is considered that the reason for this is an increase in particle-fiber adhesion force. |
