PURPOSE:To properly remove radioactive incineration ashes stuck on the inner surface of a pipe by constituting the title equipment so that a ball-like elastic purifying member is introduced from the upstream side end of the pipeline and the inside thereof is purified while utilizing air as a transfer medium and the elastic purifying member is recovered from the downstream side end. CONSTITUTION:A ball-like elastic purifying member 5 which has been extruded to the upstream side end A of a transfer pipeline 1 with an automatic feeder 3 is transferred with the air flow fed by a fan 2 while peeling attachment stuck on the inner surface of the transfer pipeline 1. The attachment is collected with a collection net 9 in the downstream side end B. For example the ball-like elastic purifying member 5 contaminated with radioactive incineration ashes is held in a recovery rack 10 with an automatic recovery device 4 and the ball-like elastic purifying member 5 is discarded together with the recovery rack 10. Therefore purifying work of the inside of the transfer pipeline for radioactive incineration ashes can be easily performed and on evil of secondary pollution is not thoroughly caused and the safe and economical purifying work of the inside of the pipeline can be performed. |
