REDUCTION OF NOISE OF ENVIRONMENTAL POLLUTION BY INSTALLING SILENCERS
The article describes the sources of noise Yeisk thermal power plant (TPP) in excess of the permissible sound pressure levels in homes on the street. Gorky, 25. Eisk TPP is located near the residential area, where the permissible noise level standards adopted much more stringent than in the power plants. Prolonged exposure to noise leads to human disease noise disease. The scheme of movement of exhaust gases from the thermal power plant generating units Yeisk. Analysis of measurements of noise characteristics of main and auxiliary equipment showed that one of the main sources are sectioned estuaries double-barrel pipe height of 27 m and slices estuaries pipes emergency explosive valves flues installed on the roof at a height of 17 m. The previous Noise reduction nozzles that emit noise uniformly in all directions are replaced by advanced, whose index changed direction estuaries sections double-barrel tubes. This will change the level of radiated noise in residential development. If you change the angle of orientation of 135°-180°, the noise level in residential construction decreased by 7-10 dB.
