ABSTRACT:
An apparatus for cleaning heat exchanger tubes and in particular an improved collection system for nuclear generator cleaning and blasting media and deposit material. A suction line having a downwardly directed suction inlet is effective to vacuum airborne media and debris in said chamber and vacuum media and debris deposited on the bottom of said chamber below said suction inlet. A hopper, air jet and shaker means are provided to transport deposited media and debris toward the suction inlet. Breaker and partition means are provided to reduce back-streaming of debris into heat exchanger tubes.
