Grid for cleaning heat exchanger - has parallel bars mounted obliquely across exit duct of exchanger

摘要

The grid is for separating from carrier fluid, cleaning bodies leaving a tubular heat exchanger after cleaning the tubes made of bars, parallel and equidistant and sepd. by a distance smaller than the small dimension of the cleaning bodies. It is mounted obliquely across the exit duct of the exchanger. The cleaning bodies are trapped and guided along one of the grid bars to the far end of the grid where they are collected and removed from the fluid. Transverse grinding of the bodies towards the collector in two directions X and Y corresponds to two perpendicular coplanar diameters of the tube exit. The bodies are collected in flasks (6) converging towards the bottom, attached to the edges of the upper face of the bottom of the grid.
