Sedimentation tank filled with fin-mounted ramp type precipitator

Abstract

The invention relates to settling tank equipped with ramp precipitator with flap, belonging to purifier field. The invention aims to solve low efficiency of settling tank provided with normal precipitator. The lower side face of tipping plate (3) on ramp precipitator (1) is equipped with regularly-distributed flap (4); the two near tipping plates and flaps forms diamond inclined tube settling unit (5) which is similar to inclined tube precipitator; said settling unit is provide with a precipitating main flow zone (6) on upper side and sludge passage (7) on lower edge part; tipping plates (3) are superimposed arranged to construct unit total program (12) of ramp precipitator, and they can also format settling tank. The invention is characterized in that the gliding speed of granular sludge is high, distance is short, sludge stacking problem is avoided, for which the settling efficiency and water treatment effect are improved; and when the surface area of settling tank is certain, the settling area is increased, thus the load of settling tank is increased. The device is easy to be produced, assembled and maintained.

Description

technical field [0001] The invention belongs to the field of water purification devices and relates to a settling tank filled with a slanted plate settler with fins. Background technique [0002] In the prior art, the inclined plate (tube) sedimentation tank is composed of many inclined plate (inclined tube assembly) settlers at a certain angle with the horizontal plane placed in the sedimentation tank. It is filled in the sedimentation tank as a whole suspended in a consistent inclined direction, the water flows from bottom to top, or from top to bottom (the inclined plate sedimentation tank can also be along the horizontal direction), and the sludge particles sink on the inclined plate (inclined tube assembly ), when the particles accumulate to a certain extent, they will automatically slide down, and the accumulated sludge will be cleaned out of the pool regularly. The disadvantage is that sludge and flocs are easily accumulated at the corners of the sloping plate (incli...

AI Technical Summary

Problems solved by technology

The disadvantage is that sludge and flocs are easily accumulated at the corners of the sloping plate (inclined tube), which reduces the sludge discharge area and increases the local flow velocity in the sloping plate (inclined tube), thereby increasing the amount of sludge. The falling jacking force will further increase the sludge accumulation, resulting in a vicious cycle of sludge accumulation, and thus prolong the journey from sludge sedimentation to discharge. The sludge on the ) is rolled up, and the phenomenon of mud gushing occurs, which seriously deteriorates the water quality; on the other hand, the overall suspended space above the bottom of the sedimentation tank stores the sludge that has fallen down, although the bottom of the tank is sloped, which is beneficial to sludge However, due to the overall large bottom area and insufficient driving force, the bottom of the sedimentation tank is prone to mud accumulation. The result of mud accumulation will not only increase the bearing load on the bottom of the pool, but also affect the bottom of the inclined plate (inclined pipe). The deposited sludge slides down, affecting the sedimentation efficiency and water treatment effect
