Abstract

In terms of cleaning gas streams from small up to medium volume flows fibrous filters are one of the most common technologies for separating particles or droplets. Fibrous filters offer several advantageous such as low investment and operating costs. For that reason these filters find applications in a broad field (power plants, spray drying, HEPA-filter for clean rooms, air cabin filters for cars…).

Description

Challenges and limitations of using fibrous filters is their limited separation efficiency for particles in the submicron range (<1µm) and limited life cycles of filter systems as consequence of caking and increase of pressure drop during loading the material with particles. Because of the health hazard of particulate matter there are strict environmental specifications for emitting these particles. For that reason it is desirable to develop fibrous filter systems which are able to deal with this challenges (High separation efficiency, low pressure drop and long life time cycles) under varying operating conditions, also for particles in the submicron range.  

Based on CFD-simulations for prediction the performance of fibrous filters novel fibrous filter systems should be developed having improved separation efficiencies.

Aims of the project

·         Development of simulations for prediction the performance of fibrous filters under consideration the morphology

·         Evaluation the relationship between the different separation mechanism and the morphology

·         Experimental validation of simulations

·         Design and evaluation of fibrous filters with improved separation performance
