Equipment advantages of professional small pitch inclined plate sedimentation tank 

  The water flow in the inclined plate (tube) sedimentation tank of small spacing inclined plate sedimentation tank is in a laminar flow state in theory, but actually it is not. In fact, the water flow in the inclined tube sedimentation tank is pulsating, because when the large alum particles in the inclined tube produce relative movement with the water during sedimentation, small vortices will be generated behind alum particles, and the movement generated by these vortices causes the pulsation of the water flow. These pulsations have no effect on the large alum particles, but play a supporting role in the sedimentation of small particles with incomplete reaction, thus affecting the effluent quality. In order to overcome this phenomenon and suppress the pulsation of water flow, small pitch inclined plate sedimentation equipment came into being.

This equipment has the following advantages: as the spacing is significantly reduced, the alum settling distance is also significantly reduced, so that more small particles can be settled; As the spacing decreases, the hydraulic resistance increases, making it the main part of the flow resistance in the sedimentation tank. In this way, the flow in the sedimentation tank is evenly distributed. Compared with the inclined pipe, the sedimentation conditions are obviously improved; The sludge discharge performance is much better than that of other shallow sedimentation tanks, because this kind of equipment basically has no lateral restraint, and the sedimentation area of the equipment is equal to the sludge discharge area.

Inclined plate (tube) sedimentation tank Inclined plate (tube) sedimentation is to place many inclined plate filler (tube) components of sedimentation tank at a certain angle to the horizontal (generally 60.) in the sedimentation tank. The water can flow from bottom to top or from top to bottom, and the particles will sink at the bottom and then slide down automatically. According to the analysis of improving the hydraulic conditions of the sedimentation tank, because the hydraulic radius of the sedimentation tank is greatly reduced, the Reynolds number R is greatly reduced, and the Froude number is greatly increased, meeting the requirements of water flow stability and laminar flow. In order to further improve the sedimentation efficiency, many improved inclined plate (tube) sedimentation tanks came into being.
