AI Technical Summary
Existing jet aerators cannot simultaneously achieve high-intensity mixing and high oxygen mass transfer efficiency, resulting in poor mixing or failure to fully realize oxygen mass transfer potential, thus limiting the performance improvement of wastewater treatment systems.
The multi-stage extrusion spiral mixing jet aerator, including a water inlet pipe, an air inlet pipe, an extrusion mixing chamber, a double-spinning spiral ribbon mixing chamber, and a six-pronged rotating nozzle, achieves multi-stage pretreatment, mixing, and shearing of gas-liquid-solid multiphase fluids through designs such as spiky grids, guide cloud soft rings, segmented textured extrusion ball bowls, and inner and outer double-layer spiral ribbons, thereby promoting bubble breakage and oxygen transfer.
It increases the gas-liquid contact area and mixing uniformity, enhances oxygen transfer efficiency, solves the problems of poor mixing effect and low oxygen mass transfer efficiency, and improves the overall performance of the wastewater treatment system.
