高位集水冷却塔集水装置内空气流场的研究
Research on the Air Flow Field Inside the Water Collecting Devices of the Cooling Tower With the WCDs
摘要
Abstract
In the wet cooling tower with water collecting devices (WCTWCD), the water collecting devices (WCDs) are installed in the air inlet, the rain zone in the conventional wet cooling tower (CWCT) is eliminated. The cooling performance of the WCTWCD is different from that of the CWCT since the rain zone is substituted by the WCDs. These differences are closely related to the air flow field in the WCDs. The wind tunnel experiment and the numerical simulation were incorporated firstly to analyze the air flow field inside the WCDs. The impact of the inclined angle and the aisle spacing on the air flow field inside the WCDs were studied. In the studied scope, the larger inclined angle and wider aisle spacing make the air flow field more uniform and steady. The energy loss of the air is also less with larger inclined angle and wider aisle spacing. Then the author proposed a new structure of WCDs which can prevent the cooling water from splashing and make the air flow field better. Finally, equations regarding the drag coefficients of different kinds of WCDs were put forward, laying the foundation for the future study of the WCDs.关键词
