PROBLEM TO BE SOLVED: To efficiently heat a treated material to which combustibles adhere highly accurately, and pyrolyze the combustibles at an appropriate protective atmosphere flow rate.SOLUTION: Pyrolysis equipment includes: a double cylindrical rotary furnace 10 having a treated material input port 11 on the rear side and a discharge port 12 on the front side, inclined so that the rear side becomes higher and comprising an outer cylinder 13 and an inner cylinder 14; a rotary drive mechanism 20; a gas heating device 30; a first duct 41 for sending gas 200 from the rear side of the rotary furnace 10 to the gas heating device 30; a second duct 42 for sending the gas 200 to the rotary furnace 10 side; an outer cylinder supply duct 42A and an inner cylinder supply duct 42B branched from the second duct 42 and connected to the outer cylinder 13 and the inner cylinder 14 from the front side of the rotary furnace 10; a control mechanism 50 provided in the vicinity of a connection position between the outer cylinder supply duct 42A and the inner cylinder supply duct 42B; and a flow rate control device 51 for determining an opening of the control mechanism. The input port 11 is provided on the inner cylinder 14 side on the rear side of the rotary furnace and a treated material 100 is supplied from the rear side to the front side through the inner cylinder 14.SELECTED DRAWING: Figure 1 【課題】可燃物が付着した被処理材料を高精度で効率的に加熱すると共に、適正な保護雰囲気流量で可燃物を熱分解する。【解決手段】被処理材料投入口１１が後方に前方に排出口１２が設けられ後方を高く傾けた、外筒１３と内筒１４の二重円筒状回転炉１０と、回転駆動機構２０と、ガス加熱装置３０と、回転炉１０の後方からガス２００をガス加熱装置３０に送る第一ダクト４１と、ガス２００を回転炉１０側に送る第二ダクト４２と、第二ダクト４２から分岐して回転炉１０の前方から外筒１３及び内筒１４に接続された外筒供給用ダクト４２Ａ及び内筒供給用ダクト４２Ｂと、外筒供給用ダクト４２Ａと内筒供給用ダクト４２Ｂの接続位置付近に設けられた制御機構５０と、制御機構の開度を決定する流量制御装置５１を備え、投入口１１を回転炉後方の内筒１４側に設け、後方から前方に内筒１４を通じて被処理材料１００を供給する。【選択図】図１
