METHOD FOR ADJUSTING WATER TEMPERATURE REGIME IN TAIL RACE OF A DAM AND DEVICE FOR IMPLEMENTING THE SAME Russian patent published in 1996 - IPC

FIELD: hydraulic engineering, water development works. SUBSTANCE: water intake from water reservoir 3 is carried out concurrently by deep water intakes 9 and surface water intakes 10 and the water is bypassed to tail race through different water conduits 8. The water is stabilized without mixing. Water taken from surface layer is aerated prior to entering tail rice. The aeration is carried out by spraying air in it. Then it is directed to upper layer of the river between water sides 1 and 2 using stabilizing/guiding structure 15 that provides the stabilization and aerated water flow spreading over upper layer of tail race of the dam between water sides. Water aerating rigs 13 and 14 are made in the form of ejector and air sprayer open to compressed air source. Surface water intakes 10 are separated from each other in plane by deep water intakes 9. Each stabilizing/guiding structure 15 is made in the form of well 20 formed with overflow wall 21 being arced in plane and L-shaped in cross section, and separating lateral walls 22. EFFECT: more effective water temperature adjusting. 5 cl, 2 dwg
