Abstract

A device for diverting discrete cleaning bodies carried in a fluid flowing through a tubular heat exchanger from the main stream of the fluid consisting of a diverter casing through which an axial current flows and a separating sieve system disposed therein having at least one sieve surface disposed at an angle to the flow and terminating at the downstream end in a lateral outlet connection. The at least one sieve surface being pivotable for cleaning purposes to such an extent that the sieve surface that was on the upstream side comes to be situated on the downstream side. The at least one sieve surface terminates in the vicinity of the diverter casing wall and a transition surface is disposed between the upstream sieve surface and the casing wall, the radius of curvature or angle between the transition surface and the casing wall being selected such that the cleaning bodies are prevented from becoming wedged.
