| Since the construction of Guangzhou Metro Line No. 1 June 28, 1999 officially opened since 2010, has been owned by 8 lines, with a total length of more than 200 kilometers of rail line network. In addition to line 2 Haizhu square station using the Pearl River water as cooling, the rest are cooling tower cooling. Mainly low-noise cross-flow cooling towers, sub-station cooling station to use more parallel operation of two cooling towers, concentrated cold station with multiple units operating in parallel. To meet the requirements of urban planning, combined with the specific circumstances of the station, Guangzhou Metro Line has been operating mainly in the cooling Tabu set the following form: 1, together with the construction of subway air pavilion; 2, sunken arrangement; 3, together with the construction of the property; 4, the ground layout. Layout due to different cooling tower on the surrounding environment caused by noise pollution, thermal pollution, and their thermal performance varies.The noise of a typical cooling tower, water temperature, cooling tower water temperature, the cooling tower inlet air temperature, relative humidity, inlet cooling tower, cooling tower outlet temperature, relative humidity, the wind cooling tower, cooling water flow, then water cooling tower plate temperature distribution, temperature and humidity, atmospheric pressure and other operating parameters for field testing, for a typical cooling tower noise control site to discuss the situation, and different noise reduction measures under the conditions of the cooling tower thermal performance analysis.Through the data analysis and evaluation, research noise pollution, thermal pollution and the correlation between the thermal performance, ways of improving the cooling tower cooling capacity, reduce noise pollution and thermal pollution of the method for optimization of cooling tower design and energy-saving operation to improve reference . |
