CFD modelling of a bag filter plant for flue gas cleaning under consideration of flow shift and particle deposition relocations

U. Heck*, M. Becker, DHCAE Tools GmbH, Germany

Presentation at FILTECH 2022 Conference

Bag filter systems for exhaust gas purification are characterized by a large number of bag filters (usually over 1000), which are loaded with dust particles and cleaned at regular intervals with a pressurized medium. In plant operation, malfunctions often occur due to uneven loading of the filters, which leads to reduced service life with typically high repair costs and plant downtime. In the problem at hand, a bag filter system for flue gas cleaning in a power plant operation showed several failures within one year, in which cracks occurred in the filter fabric of individual bags. As a result, the specifications for air pollution control could no longer be met. The plant had to be shut down frequently and defective filters had to be replaced.

The size of the bag filtration plant with its high number of filters to be considered, the complex dynamic interactions between the continuous particle deposition on filters, the local increase in flow resistance at the filter and the associated flow and deposition relocation make it difficult to optimize the plants with typical flow simulation tools. Since common CFD tools cannot take these interactions between deposition, resistance increase and flow shift into account, adapted calculation tools are required especially for these problems.

In the case study presented here, the CFD modelling was done using the filter modelling tool from DHCAE Tools based on the CFD toolbox OpenFOAM. The modelling extension uses an Eulerian-Lagrangian approach whereby the interactions between filter loading, shift of the continuous flow due to the increase in resistance and subsequent particle deposition are considered in an iterative process.

The meshing of the geometry is of particular importance in the implementation of the simulation model: to be able to resolve the large number of bag filters in the iterative loading process, a particularly efficient meshing technique is required to ensure high mesh quality with lowest number of elements possible. This was achieved by...
