The development and growth of urban areas is indispensable for urban planning and construction. The colorful urban life also requires mass cultural activities and entertainment projects. However, with the rapid development of urban areas in Guangdong, urban construction sites in full swing and KTV, bars and other recreational clubs with constant music have become a source of production noise, giving urban areas a peaceful day and night. noise. The planned and effective comprehensive control of noise and the restoration of calm in urban areas have become a top priority task for the administrative department and the municipal integrated administrative brigade.
In order to create a quiet and comfortable task and living environment for the citizens, the noise problem of urban construction sites and night leisure and entertainment clubs that the citizens respond strongly to, the price of noise control of cooling towers, starting this year, the city's comprehensive administrative staff, the price of noise control of cooling towers , Conduct environmental noise pollution inspections on major construction sites and recreational clubs in the urban area. Industrial equipment noise control, noise control has long been an urgent environmental pollution problem.
During this year’s high school and college entrance examination, the city’s comprehensive administration will do a good job of environmental noise pollution during the high school and college entrance examination to ensure that candidates will not be disturbed by noise. Surrounding the test sites, make great efforts to deal with noise sources within 100 meters of the test sites and candidates’ accommodation Achieve quick response, immediately investigate and deal with, and clarify responsibilities, and the responsibilities are to people. Industrial equipment noise control, noise control has long been an urgent environmental pollution problem.
It is reported that from June 7th and 8th of the college entrance examination to June 11th and 12th of the senior high school entrance examination, more than 3 personnel will be assigned to work at each test site and candidate’s accommodation to maintain the candidates’ preparation and preparation 24 hours a day. Exam environment. According to statistics, on the day of the college entrance examination, a total of 36 noise pollution cases were investigated and dealt with, and 90 cases were advised.
Noise is generally divided into several types: traffic, construction, industry, and social life noise. Because the sources of social life noise are more common, the "Noise Pollution Prevention and Control Law" does not subdivide these. In the process of comprehensive management of social life noise pollution In the absence of corresponding laws and regulations, regulations on the prevention and control of noise pollution in social life can clarify the management regulations of various departments, which is more conducive to the prevention and control of noise pollution in social life. Noise control, noise treatment, factory noise control and production equipment noise control must be based on laws.
At present, there are more and more models and specifications of cooling towers, and low-noise cooling towers and ultra-low-noise cooling towers continue to emerge. When selecting cooling towers, use mitigation methods in cooling towers. Because of the process regulations, when the selected cooling tower has a large noise source and cannot meet the noise function requirements, noise reduction, shock absorption, and sound insulation can be used to alleviate the noise of the cooling tower. Source strong. The noise sources of cooling towers mainly include fan noise, water pump noise, and falling water noise. The basic way to alleviate noise is to assemble shock-absorbing methods of various mechanical equipment, such as shock-absorbing pads and shock-absorbing springs, to prevent equipment vibration and noise. Secondly, a muffler is assembled at the inlet and outlet of the cooling tower fan. A reasonable and effective muffler can reduce the noise of the tuyere by about 10%. Secondly, water permeable materials such as metal mesh and polyurethane can be set on the bottom plate of the tower body to reduce the falling water height and so on. Finally, the noise of water pumps and fans can be alleviated according to the assembly of frequency converters.
Under the condition of achieving the ventilation coefficient, set the cooling tower cover of sound insulation equipment on both sides of the cooling tower. Normally, the sound insulation method can achieve the effect of 56.
