On this basis, in order to further increase the flocculating effect in waterpower flocculation tank 5, each of the gallery 11 is heavy
Be provided in shallow lake subregion 17 one it is vertical around fluidization tower 18.By being preferably provided with around fluidization tower 18, make liquid in the mistake of flowing
Vortex is generated in journey, is improved the collision probability of floccule body and impurity, is further improved flocculating effect.Since waterpower is flocculated
In the process, the floccule body formed should be greater than by, which being vortexed, is just avoided that the floccule body for blending and having formed, but the excessive and meeting that is vortexed
Excessive loss flows waterpower, reduces flocculation rate.For this purpose, the present invention preferably uses down big up small setting around fluidization tower, also
It is to say, as shown in figure 4, described gradually become smaller from the bottom to top around fluidization tower 18.So that bottom and the liquid on upper layer are being flowed through around fluidization tower
After 18, appropriately sized vortex can be generated, smaller, lower layer the vortex of vortex on upper layer is bigger.This flocculates with bottom bulky grain
Body is more, the distribution relation more than the little particle floccule body of upper layer just coincide.Setting in this way, the present invention neither influence floccule body
Further flocculation, and unnecessary hydraulic loss can be prevented, guarantee flocculation rate.Further, in order to be promoted around fluidization tower 18
The ability being vortexed is excited, it is described to be provided on the circumferential surface of fluidization tower 18 along the helical form water conservancy diversion tooth extended around 18 length direction of fluidization tower
19.In addition, adjacent two are sunk in remaining gallery 11 in the waterpower flocculation tank 5 in addition to a gallery 11 close to teeter chamber 4
It is interlaced around fluidization tower 18 in shallow lake subregion 17, it is interlaced to ensure liquid in entire flow section around fluidization tower 18
Each position has vortex to generate, and keeps flocculation everywhere more balanced.
