Circulating water outfall structure for thermal power plant
The invention discloses a circulating water outfall structure for a thermal power plant. The circulating water outfall structure comprises a discharge chute formed in the tail end of a drainage channel, two side wing walls, a stilling pool and a stilling pool outlet end wall, wherein broken line-shaped guide walls for heat dissipation are arranged in the stilling pool along the water flow direction. The pair of broken line-shaped guide walls is arranged in a mirror symmetry mode by using the center of an outfall, the broken line-shaped guide walls adopt four sections of broken lines, the four sections of broken lines are used for equally dividing the stilling pool along the water flow direction, the broken point of each section of broken line is located on the cross section of the equally divided stilling pool, the first section and the third section are diffusion sections, the second section and the fourth section are contraction sections, and the included angle between the two connected sections of broken lines is 160-175 degrees. After warm discharge water in the thermal power plant drains through the drainage channel, plane diffusion of a water flow is completed in the discharge chute, so that the contact area of the warm discharge water and air is increased and is beneficial for heat dissipation. After the water flow enters the stilling pool, under the guide of the broken line-shaped guide walls, a vortex flow in the horizontal direction is generated while a vertical hydraulic jump is formed in the pool, so that the water flow is sufficiently aerified, the heat exchange of the water flow and surrounding air is strengthened, the temperature of the warm discharge water in the thermal power plant is effectively reduced, and the heat pollution for receiving water is reduced.
