PROBLEM TO BE SOLVED: To provide a heat storage type waste gas treatment device provided with means for treating waste gas such as silicone oil producing a solid inorganic compound upon combustion, preventing the closure of heat storage materials or the increase of pressure loss even when a sintering is generated at a high temperature part, suppressing the increase of power energy of a fan and performing a stable operation. SOLUTION: In the heat storage type waste gas treatment device, a plurality of heat storage chambers including a heat storage layer 3 in which when high temperature treated waste gas from a furnace (waste gas treating zone) 4 flows, heat is stored, and when low temperature untreated waste gas flows, the stored heat is discharged to preheat the untreated waste gas are made to communicate mutually through the waste gas treating zone. The supply and exhaust directions of the waste gas are sequentially switched to treat the untreated waste gas. The heat storage layer 3 is formed by laminating a plurality of steps of honeycomb type heat storage materials. The diameter of the cell of the honeycomb type heat storage material 7 at least in an outlet side is larger than the diameter of the cell of the honeycomb type heat storage material 8 on other step. |
