摘要： PROBLEM TO BE SOLVED: To perform a stable operation for a long period by preventing the closure of an opening part of a heat storage material through which untreated waste gas flows in a heat storage type waste gas treatment device. SOLUTION: The heat storage type waste gas treatment device comprises a furnace 4 for treating the untreated waste gas including VOC at high temperature, a heat storage layer 3 of honeycomb shape in section for preheating the untreated waste gas and removing heat of treated waste gas and a distributing valve 2 for distributing the untreated waste gas to the high temperature heat storage layer. A pressure loss part of a waste gas passage is detected in accordance with the differential pressure of the heat storage layer, and the rotation of the distributing valve 2 is controlled to adjust the flowing time of the high temperature treated waste gas flowing through the heat storage layer 3, so that the pressure loss part is heated to 450 to 500 deg.C. Thus, adhering silicone oil is rapidly oxidized to become silica particles. The silica particles can be simply removed by a blower to suppress the closure of the waste gas passage with a stable operation.

摘要： PROBLEM TO BE SOLVED: To reduce a boundary film diffusion resistance in gas flow paths and enhance a catalytic performance without changing a catalyst manufacturing process by providing a cut part traversing plural parallel gas flow paths. SOLUTION: Cut parts 3 reaching the half of the depth of a honeycomb cross section perpendicularly with gas flow paths 2 are alternately provided from two oppositely positioned side faces. In addition, the cut parts 3 are alternately formed at a specified interval on the same side face to reduce a boundary film diffusion resistance and thereby enhance a catalytic performance. The flow paths 2 are cut off through the entire cell of the honeycomb 1, together with the cut parts 3 from the opposite direction. Therefore, it is expected that the activity of the entire cross section of the parallel gas flow paths 2 can be uniformly enhanced. Further, the cut parts 3 need not be provided perpendicularly with the gas flow paths 2 but can have a specified angle with the gas flow paths 2. Thus, it is possible to enhance the catalytic efficiency by preventing the boundary film diffusion resistance from increasing in the gas flow paths 2 almost without changing a manufacturing process.
