A cleaning body intercepting apparatus for a tube-type heat-exchanger, with the apparatus including a cylindrical body, a pair of outer gratings disposed in the cylindrical body so as to receiving cleaning bodies from the heat-exchanger, at least a pair of inner gratings within the outer gratings for forming a pair of throat portions each adjacent to the side wall of the cylindrical body, and extraction tubes each disposed under each of the throat portions. The pair of throat portions each are surrounded by the outer and inner gratings so that the cleaning bodies from the heat-exchanger are introduced into the throat portions. The cleaning bodies passed through the throat portions are taken out the cylindrical body through the extraction tubes.
