普通沉淀池的设计,仅利用重力作为矾花分离的推动力,而且是在静态流况下分离。近来,普通沉淀池,在美国多设计成斜管沉淀池,在日本多设计成侧向流斜板沉淀池。这种沉淀池,在层流状态下溢流率很低。作者在斜板上装上了与水流方向正交的直立的叶片,使矾花进入在叶片后形成的许多旋涡内,而进行动态分离。从而克服了普通沉淀池的限制,提高了溢流率,达到较高的分离矾花效率(过去国内称为迷宫式斜板)。在研究中,这种新的动态分离法所具有的高效率,已被实验和对实际设备的调查所证实。带叶片流槽的水流结构,用氢气泡(电解水)的流动显形技术确定出来。根据水流结构和矾花去除的模型试验,提出了一个说明高效能的数学模型,并测定了它的常数,为理论性设计提供计算带叶斜板分离器的可能性。
The design of ordinary sedimentation tanks only uses gravity as the driving force for the separation of the flowers, and they are separated under static flow conditions. Recently, ordinary sedimentation tanks are mostly designed as inclined tube sedimentation tanks in the United States and are mostly designed as lateral flow inclined plate sedimentation tanks in Japan. This sedimentation tank has a very low overflow rate under laminar flow conditions. The author installed the upright blades orthogonal to the direction of the water flow on the inclined board so that the creepers entered the many vortices formed behind the blades and they were dynamically separated. In order to overcome the limitations of ordinary sedimentation tanks, the overflow rate is increased, and the high efficiency of separation and flowering is achieved (in the past, it was known as a labyrinth swash plate). In research, the high efficiency of this new dynamic separation method has been confirmed by experiments and surveys of actual equipment. The water flow structure with the blade flow channel is determined by the flow visualization technology of hydrogen bubbles (electrolyzed water). According to the model test of water flow structure and sassafras removal, a mathematical model describing high-efficiency was proposed and its constant was determined. The possibility of calculating the swash plate separator with leaf was provided for the theoretical design.
