Abstract

Настоящее изобретение относится к системе аэрации воды для гидравлических турбин, которая может быть встроена в конусы отсасывающей трубы гидравлической турбины для увеличения содержания растворенного кислорода в воде, выпускаемой из гидроэлектростанций. Система аэрации воды для гидравлических турбин согласно настоящему изобретению представляет собой систему, содержащую устройство аэрации воды, которое осуществляет аэрацию посредством перфорированных пластин, которые вместе с опорной решеткой дублируют внутреннюю геометрию первоначального конуса отсасывающей трубы турбины, посредством отверстий, калиброванных относительно доли пустот, необходимой для аэрации потока в турбине. Впрыск воздуха в турбину основан на уровне давления в турбине и недостаточном значении содержания растворенного кислорода в воде, показания которых задействуют модуль управления процессом аэрации, что сводит к минимуму потребление энергии, необходимой для аэрации, за счет активации естественной аэрации без соответствующего потребления энергии или принудительной аэрации, осуществляемой с подачей сжатого воздуха.The present invention relates to a water aeration system for hydraulic turbines that can be incorporated into the suction cones of a hydraulic turbine to increase the dissolved oxygen content of water discharged from hydroelectric power plants. The water aeration system for hydraulic turbines according to the present invention is a system comprising a water aeration device that aerates by means of perforated plates, which, together with a support grid, duplicate the internal geometry of the original cone of the turbine suction tube, through holes calibrated with respect to the fraction of voids required for aeration flow in the turbine. Turbine air injection is based on the turbine pressure level and insufficient dissolved oxygen in the water, the readings of which activate the aeration control module, which minimizes the energy consumption required for aeration by activating natural aeration without corresponding energy consumption or forced aeration , carried out with the supply of compressed air.
