This disclosure the fan which generates the flow of the conveying gas the influx mouth which receives the conveying gas from the closed territory (18) with, the outlet which emits the conveying gas to the closed territory (31) with, from the influx mouth in the passage to the outlet (21) with, the decontamination steam being introduced to the flow of the conveying gas, is spat out with the flow and also outlet and the steam generator which it pollutes removes the closed space (19) with includes, the device in order it pollutes to remove the closed territory (10) it is related. Another fan (33) detouring, the passage where the decontamination steam is introduced the steam style exits (31) the melt-off pore which it adjoins (32) from is forwarded forwarding another gases style from the closed territory which to the closed territory, it assists the fact that it makes the conveying gas which contains the decontamination steam territory the whole closing disperse.本開示は、閉鎖領域から搬送ガスを受け取る流入口(18)と、搬送ガスを閉鎖領域へ吐出する流出口(31)と、流入口から流出口への通路において搬送ガスの流れを発生させるファン(21)と、汚染除去蒸気が搬送ガスの流れへ導入されて流れとともに流出口で吐出され閉鎖空間を汚染除去する蒸気発生器(19)とを包含する、閉鎖領域を汚染除去するための装置(10)に関連する。別のファン(33)が、汚染除去蒸気が導入される通路を迂回して蒸気流出口(31)に隣接する流出孔(32)から閉鎖領域へ送出される閉鎖領域からの別のガス流を送出して、汚染除去蒸気を含有する搬送ガスを閉鎖領域全体に分散させるのを補助する。
