Research on comprehensive treatment technology of waterspouting noise of large natural draft cooling tower

Abstract

Abstract:

Due to the improvement of the functional classification of sound environment, the original noise barrier reduction measures for cooling towers cannot meet the second class requirements of ‘Emission standard for industrial enterprises noise at boundary’. Retaining the acoustic barrier structure of the original cooling tower, it takes full consideration of the old facilities, capital of investment and noise reduction etc. It puts forward three different design solutions which are adding silencing mat, improving original noise barrier and adding new sound absorption channels. Through the comprehensive comparison and analysis of these noise reduction design, it recommend the solution of increasing the height of the original linear sound barrier and adding inside sound absorption

Key words:

thermal power plant, cooling tower, noise barrier, waterspouting noise, comprehensive treatment
