Lecturer:
Pavel Vybíral, Jiří Hemerka (guarantor)
Tutor:
Pavel Vybíral
Supervisor:
Department of Environmental Engineering
Synopsis:

Theory of particle separation in the fibrous filter layer, classification and use of room air filters and HEPA filters. Industrial fabric filters - performance, filter media, use.

Requirements:

Following requirements are demanded: Flow field around single fibre. Separation principles and overall grade efficiency of separation of single fibre and of the filter layer. Pressure drop of the filter layer and of the whole filter unit. Classification and use of filters for general ventilation. HEPA and ULPA filters and clean rooms. Industrial filtration - performance, choice of filter material and dimensioning the filter area.

Syllabus of lectures:

Industrial fabric filters and atmospheric air filters - differences and common feature. Fibrous filter layer. Particle efficiency of separation of single fibre and fibrous layer. Flow field around single fibre. Principles of particle separation. Pressure drop of fibrous layer (filter medium) and filter. Kinetics of filtration. Classification and use of filters for general ventilation. Clean rooms - definition, standardization, performance. HEPA and ULPA filters - classification and use. Industrial fabric filters, filter media, characteristic features, use.

Syllabus of tutorials:

Velocity around the fibre. Comparison of different flow fields. Calculation of individual particle separation principles of single fibre. Overall grade efficiency of the single fibre and of the filter layer. Correction on non-homogenous fibre distribution. Pressure drop of the clean filter layer and pressure drop increase with dust loading.

Study Objective:

To get fundamental knowledge and skills in area of solid particle filtration in ventilation and air conditioning and in the industry. Knowledge of designing and dimensioning of filters for individual purposes.

Study materials:

Brown R. C.: Air filtration, Pergamon Press, 1993
