Application of a Centrifugal Vane Mist Eliminator in the Gaseous Effluent Treatment in the External Environmental Air

摘要

The treatment of the gaseous effluents released to the atmosphere influences the external air quality. In the last years different equipments used in the treatment of gaseous effluent were developed. However, the treatment level is influenced by the equipment performance. In this study the treatment of gaseous effluents released to the external environmental air with a centrifugal vane mist eliminator is made. In this study, using experimental tests, the equipment performance is analysed in detail. The centrifugal vane mist eliminator is made with stainless steel zig-zag and semi-circular deflectors. The measurement is made inside the zig-zag deflectors in the semi-circular deflectors entrance. In this study the air velocity fluctuations experimental measurements, for two typical inlet air velocities, are made. The root mean square, the turbulence intensity and the power spectra, using the Fourier methodology, are calculated. In the final paper the detailed pictures of the equipment are also presented. In accordance with the obtained results, for the two typical inlet air velocity, the mean air velocity, the air velocity root mean square, the air turbulence intensity and the power spectra energy values, in general, increase from the first to the central semi-circular deflectors and is practically constant in the fallowings. The mean air velocity, the air turbulence intensity and the power spectra energy values are higher for the high inlet air velocity than for the low inlet air velocity. It is also verified that the mean air velocity values in the external zig-zag deflector are smaller than the central zig-zag deflectors.
