Rhombus perforated water-distributing lattice wall for pre-sinking aeration tank of water intake pumping station and rectifying method thereof

Abstract

The invention relates to a rhombus perforated water-distributing lattice wall for a pre-sinking aeration tank of a water intake pumping station and a rectifying method thereof. The rhombus perforated water-distributing lattice wall comprises an incoming flow water pipeline and a pre-sinking tank; the incoming flow water pipeline is communicated with an inlet of the pre-sinking tank; a first rhombus perforated water-distributing lattice wall is arranged at the inlet of the pre-sinking tank; a second rhombus perforated water-distributing lattice wall is arranged in the pre-sinking tank; a distance between the second rhombus perforated water-distributing lattice wall and the first rhombus perforated water-distributing lattice wall is 0.1 times of the length of the pre-sinking tank; the height of the first rhombus perforated water-distributing lattice wall and the height of the second rhombus perforated water-distributing lattice wall are both 0.56 times of the width of the pre-sinking tank; a plurality of vertical rhombus holes are formed in the first rhombus perforated water-distributing lattice wall; horizontal rhombus holes are formed in the second rhombus perforated water-distributing lattice wall; the vertical rhombus holes are distributed in the first rhombus perforated water-distributing lattice wall in a staggered form. According to the invention, the velocity distribution of water flow in the pre-sinking tank is more uniform and smooth and the settling effect of solid particle suspensions, such as silt, is promoted.

Description

technical field [0001] The invention relates to a diamond-shaped perforated water distribution flower wall for a pre-settled aeration tank of a water intake pump station and a rectification method thereof, belonging to the technical field of water conservancy engineering design. Background technique [0002] The pre-sedimentation tank is an important part of the water intake pumping station, and it plays an important role in the settlement of the suspended solid particles of the sediment. When the water flows from the water source into the pre-settling tank by itself through the pipeline, the water contains a large amount of suspended solids such as sediment. In order to make the suspended solids such as sediment settle in the pre-sedimentation tank as much as possible, it is necessary to ensure that the The water flow is smooth and uniform, and a perforated flower wall is usually set at the front end of the pre-sedimentation tank for water distribution.

Problems solved by technology

[0003] Engineering practice has found that after the water distribution flower wall is installed in the pre-sedimentation tank, the water flow through the water distribution flower wall still needs a long adjustment to make the water flow velocity in the pre-sedimentation tank uniform, and the water flow behind the water distribution flower wall is disturbed. Poor, affecting the sedimentation effect of the water flow in the pre-sedimentation tank
