FIELD: motors and pumps.
SUBSTANCE: noise-reducing device and reduction method for aerodynamic noise and structural vibrations resulting from water steam operating in air-cooled condensers at power plants. Interacting flow between splitters creates aerodynamic noise and structural vibrations to be eliminated to the maximum extent by means of fluid flow obstruction in splitters through the selected flow sections. The splitters contain a set of discs with channels for fluid. Fluid channels are blocked in continuous and non-separated sections of splitter to guide radial flow to the side of adjacent splitters. This allows for eliminating interacting flow. The said method, splitter and noise-reducing device help to reduce aerodynamic noise and structural vibrations resulting from turbine by-passing.
EFFECT: reduced aerodynamic noise and structural vibrations.
