To provide a system for further effectively collecting peeled pieces from a heat exchanger tube.
This system relates to a device for cleaning the heat exchanger tube, more specifically, an improved collection system for blasting medium and deposit for cleaning a nuclear reactor steam generator. A suction line having a suction port turned down is effective to vacuum extract the airborne medium and peeled pieces within a chamber and the medium and peeled pieces deposited on the bottom part of the chamber under the suction port. This system comprises a hopper means, an air jet means, and a shaker means in order to move the deposited medium and peeled pieces toward the suction port. This system comprises a breaker means and a partitioning means in order to reduce the back flow of the peeled piece to the heat exchanger tube.
