Sieve device - separates cleaning bodies downstream from heat exchanger in cooling water current

摘要

The heat exchanger (1) comprises several pipes (2) for cooling purposes, an inlet water chamber (3) and an outlet water chamber (4). The cooling water discharge (6) is connected to the outlet connection (5) of the outlet water chamber (4). A rotation-symmetrical sieve (7) is positioned between the flange of the outlet connection of (5) of the cooling water discharge conduit (6), and is arched in the water flow direction. The part (8) of the suction device (9) which has the water inlet aperture is fitted on a shaft (10) located on the one hand in the sieve centre, and on the other hand in the walling of the water chamber (4). This shaft is hollow for conducting away cleaning bodies (11). A pump (13) creates a suction current, which sucks the cleaning bodies into the area of the suction device (9) of the sieve (7), and feeds them back to the inlet water chamber (3). USE - In the turbine condensors of a power plant, to circulate and recirculate cleaning bodies in the cooling water current.
