COOLING TOWER STRAINER TANK AND SCREEN

摘要

A cooling system with at least one cooling tower (12,14) and multiple upper pans (22) or distribution manifold pipes is provided with a strainer tank assembly at the tower lower end in proximity to the sump (30) to receive incoming fluid for cooling, which strainer tank (54) includes a screen to strain particulate material from the inlet fluid communicated to the tower upper end and to equally distribute this fluid at the lowest elevation at a pressure with a higher static pressure component than its dynamic pressure component to avoid a requirement for a flow control valve to provide relatively quiescent fluid for fluid distribution to the tower and fluid transfer media (26) therein. A pressure relief baffle in the strainer tank (54) is operable in response to a fluid overpressure condition to bypass the screen and open fluid communication to avert catastrophic failures within the fluid circuit.
