PROBLEM TO BE SOLVED: To provide a super heat vapor treatment device for reducing heat influence around a reactor.SOLUTION: A super heat vapor treatment device 10 comprises a reactor 30 storing products to be processed, and a vapor generating part for supplying super heat vapor to the reactor 30. The reactor 30 comprises a main body 32 including an opening 33 through which a product to be processed can be fed into it and an opening peripheral edge part 34 positioned around the opening 33, and a lid 31 capable of closing the opening 33. At least one of the part corresponding to the opening peripheral edge part 34 of a surface at the opening peripheral edge part 34 of the lid 31 and a part corresponding to the lid 31 of the surface of the opening peripheral edge part 34 facing against the lid 31 is provided with a concavity 40 under a state in which the lid 31 closes the opening 33.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2018,JPO&INPIT【課題】反応炉の周囲への熱の影響を低減する過熱蒸気処理装置を提供する。【解決手段】過熱蒸気処理装置10は、被処理物を格納する反応炉30と、反応炉30に過熱蒸気を供給する蒸気発生部とを備え、反応炉30は、被処理物を内部に投入可能な開口33および開口33の周囲に位置する開口周縁部34を含む本体32と、開口33を塞ぐことが可能な蓋31とを備え、蓋31が開口33を塞いだ状態において、蓋31の開口周縁部34側の面のうちの開口周縁部34と対応する部分、および、開口周縁部34の蓋31側の面のうちの蓋31と対応する部分の少なくとも一方に凹部40が設けられる。【選択図】図4
