Kształtowanie się strat energii na suchych filtrach powietrza w zależności od materiału filtracyjnego, czasu eksploatacji filtru oraz rodzaju wyłapywanych zanieczyszczeń
(Wydawnictwa AGH, 2005) Gumuła, Stanisław; Piaskowska, Małgorzata
The paper summaries the experimental data expressing the energy loss in a filter, depending on the applied filtering material, filter type and the length of its service period. Two types of filtering materials were considered: M1 and M2, widely applied in air filters in combustion engines. The first one is designated as 29/31 LE, the other as 20/66 LE AD-G. Their permeabilty would differ significantly. Characteristics of filtering materials were collected in an experimental programme in which four types of contaminants were considered: quartz dust, municipal dust, clay and loess. Less volatile fractions larger than 60 mum were eliminated, afterwards the dusts were mixed with air forming a twophase medium with the specified concentration. Thus prepared air-dust mixture was directed to the filter. Energy losses in the filter were determined indirectly, utilising pressure loss vs flow intensity characteristics for the tested materials M1, M2 and for all considered dust types. Results are graphed as plots of power in the function of filter service period, the flow intensity in the filter being the major parameter.
