WATER SEAL DEVICE FOR CIRCULARLY COOLING MACHINE AIR DUCT

摘要

A water seal device (13) for circularly cooling machine air duct includes an annular flume (131) surrounding the air duct and a cover plate (132) installed on the annular flume (131) which has a gantry cross-section in radial direction. A side plate (133) extends into the annular flume (131) from the cover plate (132) and separates the annular flume (131) into an inner annular flume (134) and an outer annular flume (135). The inner and outer annular flumes (134, 135) connect with the air duct and ambient air respectively. Obstacles for preventing vibration of water surface are installed in the annular flume (131). The obstacles can be lightweight objects (20) floating on the water surface and also can be several dampers (21) installed on the external side wall () of the outer annular flume (135). The water seal device (13) can release the vibration amplitude of the water surface and ensure normal operation of the circularly cooling machine when air current changed in the air duct.
