A water distribution and diversion device for an inclined tube sedimentation tank

Abstract

The invention discloses a water distribution and flow guide device of an inclined-tube settling tank. An inclined retaining wall is arranged at the tail end of a water distribution region of the inclined-tube settling tank; the included angle between the inclined retaining wall and the horizontal plane is alpha; the water distribution and flow guide device is characterized by comprising a flow guide plate; the flow guide plate is divided into an upper part and a lower part; the upper half part is provided with a vertical flow guide plate; the lower half part is provided with an inclined flow guide plate; and the included angle of the inclined flow guide plate and the horizontal plane is between alpha and 90 degrees. The flow guide device disclosed by the invention, the regulation of water distribution uniformity can be realized; meanwhile, the flocculation effect is enhanced. Through the arrangement of the flow guide plate, the uneven phenomenon caused by the factors such as density flow and turbulent flow is reduced to the maximal extent; the flocculation is carried out by fully utilizing the effective volume of the water distribution region; the maximal flow rate entering the settling tank can be effectively reduced by reducing the even flow phenomenon, so that the smooth transition from flocculation to sedimentation is realized; and the disturbance action on suspending sludge, caused by inflow of a settling region, is reduced.

Description

technical field [0001] The invention relates to a water distribution and diversion device used in a water treatment sedimentation process. The device is mainly used in the water distribution area of ​​the inclined tube sedimentation tank for water treatment, which can effectively reduce the Froude number of the flow state in the water distribution area, weaken the upturning phenomenon of sediment caused by uneven water distribution, and improve the quality of effluent water. Background technique [0002] The inclined tube sedimentation tank is one of the most common treatment structures in the water treatment process, which can significantly improve the sedimentation efficiency and save the floor space. Many water treatment structures, such as high-density sedimentation tanks, are new types of sedimentation tanks developed on the basis of inclined tube sedimentation tanks. The sedimentation efficiency of an ideal inclined tube sedimentation tank should be mainly determined ...

AI Technical Summary

Problems solved by technology

The water distribution area of ​​the traditional inclined tube sedimentation tank basically does not have a dedicated flocculation area, which is not conducive to the re-accumulation of broken flocs

One of the reasons for this factor is that the inclined tube of the inclined tube sedimentation tank occupies a large area, and the water distribution area usually takes into account the function of the equipment inspection hole, so it is impossible to use this area to set up flocculation measures
