Abstract
An apparatus for separating cleaning elements from a fluid, especially a fluid traversing a heat exchanger into which the elements are introduced to clean the tubes thereof, comprises a vertical duct provided with an array of bars forming a grate inclined to the axis of the duct for separating the cleaning elenents, e.g. foam-rubber balls, from the heat exchanger stream traversing the duct. According to the invention, at the bottom of the grate there is provided a diagonal tube which extends along a chord or diameter of the tube and is provided with a longitudinally extending inlet slit into which the cleaning elements pass. The tube and slit are so oriented that the main stream of fluid passes tangentially across the tube and across the slit to create a turbulence thereat to prevent buildup of the cleaning elements at the base of the grate.
