The present invention relates to a rotational brush-type soot removing device of a selective catalytic reduction system, which includes: a cover frame formed to be joined to a reactor housing which fixates a catalyst carrier from a front side of the catalyst carrier; a blade which is arranged on the front side of the catalyst carrier and is formed to be rotated by flow of exhaust gas; a brush which is attached to a rear side of the blade, is rotated as the blade rotates, and sweeps out soot attached to the front side of the catalyst carrier; and a driving unit formed to move the blade and the brush in forward and backward directions with respect to the catalyst carrier. |
