Apparatus for separating dirt-particles from cooling water in power-plants

Abstract From the Canadian patent

An apparatus for removing solid particles from cooling water having a tubular housing a funnel-shaped trap, sieve attached to the inner housing wall with the tip facing in the flow direction, and a pressurized water sprayer. The sprayer includes a washer arm, concentrically rotatable about the downstream side of trap sieve, and having at least one slit nozzle directed toward the downstream surface. A suction tube extends into a collecting chamber of trap sieve. To prevent large particles from jamming rotating components, trap sieve is cleaned by spraying water only against the downstream side. The tip of the sieve is defined by a cylindrical container having a closed bottom. The intake end …
