Multi-layer lattice precipitation separating device for V-shaped pipe

Abstract

The invention discloses a multi-layer lattice precipitation separating device for a V-shaped pipe. The device is characterized by comprising multiple groups of parallel vertical plates, each group of parallel vertical plates is formed by a left vertical plate and a right vertical plate, a plurality of oblique clapboards are arranged between the left and right vertical plates, the left and right vertical plates and two adjacent clapboards form a water passage with a parallelogram-shaped cross section, a mud discharge hole is formed above the intersected part of the right vertical plate and the clapboard, a mud discharge passage is arranged between each right vertical plate and clapboards in another group of adjacent parallel vertical plates, and two ends of the mud discharge passage are sealed to form a static liquid area. As the vertical plates are adopted in the invention, the precipitation efficiency is improved, and simultaneously the vertical plates are more convenient to construct.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a device for separating water and suspended matter in a sedimentation tank. Background technique [0002] With the development of urban water supply, various forms of sedimentation tanks developed from shallow pond theory have also been widely used. Including inclined plate sedimentation tanks, inclined tube sedimentation tanks, labyrinth sedimentation tanks, etc., but the above-mentioned sedimentation tanks (including the same direction, different direction, and horizontal sedimentation tanks) have the following disadvantages: [0003] 1. When water flows through inclined pipes or inclined plates (in the same direction or in different directions), the direction of water flow needs to be changed, and the state of water flow changes, which is not conducive to the precipitation of suspended solids; [0004] 2. In the process of water flowing through the inclined tube or inclined plate, ...

AI Technical Summary

Problems solved by technology

[0003] 1. When water flows through inclined pipes or inclined plates (in the same direction or in different directions), the direction of water flow needs to be changed, and the state of water flow changes, which is not conducive to the precipitation of suspended solids;

[0004] 2. In the process of water flowing through the inclined tube or inclined plate, it will have the effect of scouring and agitating the settled suspended solids, and the settled suspended solids will often be stirred up again by the water flow, resulting in reversible precipitation of the suspended solids;

[0005] 3. When the inclined tube (inclined plate) assembly is installed, two triangular dead zones will be formed, which reduces the utilization rate of the sedimentation tank and reduces the water flow area

[0008] 2. The mud passage has a certain inclination, and the sludge is easy to stay on the slope plate of the mud passage and cause blockage, which requires frequent flushing of the mud passage
