摘要:

浙江某新建天然气燃机热电厂由于场地限制,采用机力通风冷却塔。由于该工程处于城市区域,其噪音标准为环境Ⅱ类标准,故其降噪要求较高,在前期技术选型中已考虑通过相应的技术手段,使得机力通风冷却塔本体噪音降至最低;在后期又进行了进、出风口降噪措施,使冷却塔整体噪声控制顺利达到环境Ⅱ类标准要求。

Abstract:

Owing to space limitation, a mechanical draft cooling tower is adopted for a certain newly built gas turbine thermal power plant in Zhejiang. Furthermore, because that the project is located in urban area, the noise reduction requirement is higher, and the noise environment is needed to reach Ⅱ class standard. In the early technology selection period of this project, some technical measures are considered to reduce the body noise of a mechanical draft cooling tower to a minimum, with some noise reduction measures for air inlet and outlet are also adopted in later period, the whole noise control of the cooling tower is successfully to meet the requirement of environmental Ⅱ class standard.
