Sewage discharging diffuser
The invention discloses a sewage discharging diffuser. The sewage discharging diffuser comprises a main pipe. A rising pipe communicating with the main pipe is installed on the main pipe, and a spraying pipe communicating with the rising pipe is installed on the rising pipe. The rising pipe and the spraying pipe are transitionally connected through a transition pipe, and an impeller is arranged inthe spraying pipe. After the transition pipe is optimized, the sewage flow states in the diffuser are uniformly distributed, backflow and flow-stagnation areas are avoided, and the local head loss and energy loss of the sewage at a bend or branch junction of the diffuser are reduced; and the impeller arranged at the nozzle end of the spraying pipe can change the flow direction of the sewage afterflowing out, so that the sewage quickly disperses to the periphery of a nozzle, the sewage is fully mixed and diffused with an environmental water body in a short time, a better initial dilution anddiffusion effect is achieved, and the impact on the water environment function area is reduced as far as possible.
本发明公开了一种污水排放扩散器，包括主管，所述主管上安装有与所述主管相连通的上升管，所述上升管上安装有与所述上升管相连通的喷管，所述上升管与喷管之间通过过渡管过渡连接，所述喷管内装有叶轮。本发明通过过渡管优化后，使扩散器内污水流态分布均匀，避免存在回流和滞流区域，减少污水在扩散器弯道或分叉连接处的局部水头损失和能量损失；安装在喷管喷口端的叶轮能够改变污水出流后的流向，使污水快速向喷口四周弥散，与环境水体短时间充分混合扩散，达到较优的初始稀释扩散效果，尽可能减小对水环境功能区的影响。
