Abstract:  Presents a new double-layer aeration mechanism and achieves secondary aeration of shallow and deep water. Firstly, analyzes the characteristics of the structure of inverted umbrella aerator and submersible aerator, and then, the use of reverse thinking to extract the influence aerator performance of the main devices and design a hollow spindle inflatable, inverted umbrella coaxial double-propeller plug flow and secondary aeration structures. Finally, conducts numerical simulation analysis and model experiments, simulation results and experiment results show that the mechanism has the advantage of good bubble fragmentation effect, gaswater mixture fully, large amount of oxygen and large service area.
