Unpowered rain sewage intercepting well based on aerodynamic design
The invention discloses an unpowered rain sewage intercepting well based on aerodynamic design. The unpowered rain sewage intercepting well based on aerodynamic design comprises a drum-shaped tank body, a water inlet pipe communicating with an inner cavity of the tank body is arranged on the side surface of the tank body, after sewage enters the tank body through the water inlet pipe, rotational flow is carried out along the side wall of the tank body, and an air inlet pipe assembly and a drainage pipe are respectively arranged at the upper end and the lower end of the tank body. According tothe intercepting well, through fluid mechanics and aerodynamic design, after sewage enters the tank body through the water inlet pipe, rotational flow is carried out along the side wall of the tank body, negative pressure is formed in the middle of the inner side of the tank body, external air enters the tank body through the air inlet pipe assembly, an air column is formed in the middle of the tank body and rises along with the external water level of the tank body, and the faster the water speed of the rotational flow on the inner wall of the tank body is, the larger the formed air column is, so that a water outlet pipe of the tank body drains water at a relatively stable and uniform water outlet amount, the intercepting effect is achieved, the structure is simple, the cost is low, no movable mechanical part is arranged inside, the service life is long, the practicability is high, and the economic benefits are good.
本发明公开了一种基于空气动力学设计的无动力雨污截流井，包括鼓状的罐体，所述罐体的侧面设置有与罐体内腔连通的进水管，当污水通过进水管进入到罐体后，沿着罐体侧壁旋流，所述罐体的上下端分别设置有进气管组件和排水管。该截流井，通过利用流体力学和空气动力学设计，使得污水通过进水管进入到罐体后，沿着罐体侧壁旋流，而罐体内侧的中部形成负压，外部空气通过进气管组件进入罐体，在罐体中部形成空气柱，并且随着罐体外部水位升高，罐体内壁旋流的水速越快从而形成的空气柱越大，从而保证罐体出水管以相对平稳均匀的出水量排水，达到截流效果，结构简单，成本低廉，内部无活动机械部件，使用寿命长，实用性强，经济效益好。
