星形絮凝设备 Star-type flocculation equipment

根据紊流涡旋的控制机制,在絮凝池流道中设置隔板,并在隔板上增设翼片。隔板分隔了流动空间,使流动状态参数基本接近试验参数,隔板上设置的翼片可以看成是隔板表面粗糙度的强化,水流流经翼片,产生涡体,并脱离边壁进入紊流核心。在这样的控制方式下,最佳絮凝时间缩短至4分钟,工程应用已有5分钟的实例,絮凝效果和絮凝效率的提高是极为显著的。

According to the control mechanism of turbulent mechanism, set a separating panel in the flocculation tank, and  add fins on separating panel. The panel separates the space of flows, let the flow parameters close to the test parameters

Fins added on the separator can be seen as strengthening the separator surface roughness, the water flows through the fins, the vortex formed, and separatefrom the boundary into the turbulent core. 

Under this control mode, the best flocculation time was reduced into 4 minutes, we already have the cases with 5 minutes , the improvement of flocculation and flocculation efficiency  is very significant.
