The Transient Regeneration in the Patchy Cleaning of Rigid Gas Filters--Comparison of Modeling to Experiment

PDF Version Also Available for Download.

Description

The experimental investigations performed within the scope of the present contribution are carried out in a lab scale filter test rig, which is built according to German VDI guideline 3926. The filter coupon (15 cm diameter) under investigation is mounted parallel to the crude gas channel which enables cross flow filtration as experienced in filter housings. Besides the photometric concentration monitor and the control device, an optical measuring system is mounted on the filter test rig opposite the filter coupon. This measuring system enables the full-field in situ measurement of the dust cake height distribution on the surface of the ... continued below

Description

The experimental investigations performed within the scope of the present contribution are carried out in a lab scale filter test rig, which is built according to German VDI guideline 3926. The filter coupon (15 cm diameter) under investigation is mounted parallel to the crude gas channel which enables cross flow filtration as experienced in filter housings. Besides the photometric concentration monitor and the control device, an optical measuring system is mounted on the filter test rig opposite the filter coupon. This measuring system enables the full-field in situ measurement of the dust cake height distribution on the surface of the filter medium. From these measurements, we obtain the overall frequency of regeneration as well as the local frequencies of regeneration and the patch size distribution, as discussed later. In addition, we investigate the influence of the regeneration behavior on the filtration performance (time dependence of filtration cycle times and residual pressure drop) of the filter medium.
