PROBLEM TO BE SOLVED: To provide a fixed bed type housing which has a simple structure and is capable of efficiently preventing clogging by dust. SOLUTION: The housing has a front wall situated at the front flow side of a flow direction of a gas to be treated containing the dust, a rear wall opposed to the front wall and a bottom wall for connecting the front wall and the rear wall. The front wall has opening parts, each having a diameter larger than the diameters of dust-removing particles, and shelf boards, each extending from the lower end part of each opening part to the front flow side of the gas flow direction. Each shelf board is set so as to able to prevent falling of the dust-removing particles flowing out to the front flow side of the flow direction through each opening part. |
