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

Abstract

The invention discloses an inclined tube sedimentation tank water distribution rectification device which comprises a plurality of guide plates, wherein each guide plate is divided into an upper part and a lower part; the upper half parts are vertical guide plates with adjustable guide windows; the lower half parts are inclined guide plates; a feedback device is arranged below the guide plate; the feedback device is used for measuring the flow inside gaps among different guide plates by using a plurality of speed measuring probes; the opening direction of the adjustable guide window can be adjusted according to the flow measured by the feedback device. With the combination of different guide windows, the uneven phenomenon caused by factors such as density flow and turbulent flow can be reduced to the maximum under the condition that normal flocculation is ensured, flocculation can be achieved by sufficiently utilizing the effective volume of a water distribution area, and the flocculation effect can be improved. By reducing the uneven flow phenomenon, the maximum flow speed of water into a sedimentation area can be effectively reduced, stable transition from flocculation to sedimentation can be achieved, and the disturbance of the water fed into the sedimentation area to suspended sludge can be reduced.

Description

technical field [0001] The invention relates to a water distribution rectification device for an inclined tube sedimentation tank and its control method. The method is mainly used to control the uniformity of the flow state in the water distribution area of ​​the inclined tube sedimentation tank. By reducing the Froude number of the flow state in the water distribution area, the The upturning of the bottom mud caused by uniformity improves the quality of the effluent. 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 area. 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 by the p...
