Abstract:
1. A catalytic filter system comprising a filtration vessel having a fluid inlet and a fluid outlet, a separation wall provided in the interior of said filtration vessel and a plurality of filter candles; wherein said separation wall is oriented horizontally within the filtration vessel and divides said interior into a raw gas chamber and a clean gas chamber; wherein said separation wall comprises a plurality of openings designed to sealingly accommodate said plurality of filter candles, the filter candles arranged and operated vertically pending from the separation wall; wherein said fluid inlet is arranged in fluid communication with said raw gas chamber upstream of said plurality of vertically pending filter candles; wherein said fluid outlet is arranged in fluid communication with said clean gas chamber downstream of said plurality of vertically pending filter candles; and wherein said filter system comprises a first catalytic medium which is accommodated in said clean gas chamber downstream of said vertically pending filter candles and upstream of said fluid outlet, and the filter system further comprises a blow back device accommodated in said clean gas chamber, wherein the blow back device is positioned in the clean gas chamber upstream of the first catalytic medium, and the blow back device is arranged to blow back gas through the vertically pending filter candles into the raw gas chamber to regenerate the vertically pending filter candles; wherein said plurality of vertically pending filter candles extend from the separation wall into the raw gas chamber.
