The utility model discloses a self-priming three-mixer two-stage jet aeration device. The device is composed of a submersible pump, a self-priming three-mixer two-stage jet aerator and a pipeline system. The self-priming three-mixer The two-stage jet aerator includes a nozzle, a throat, a suction pipe, a suction chamber, a conical splitter, a mixing pipe and a water suction pipe. The device uses a submersible pump to form a high-speed and high-pressure water jet at the nozzle. Due to the viscous effect between the jet boundary layer and the air, the air is sucked into the suction chamber and mixed with the water jet in the throat, and the liquid-gas mixture passes through the cone. The splitter splits the flow and cuts it into the three mixing tubes arranged radially. Under the turbulent diffusion and carrying action of the liquid-gas mixture, the water in the aeration tank is sucked into the mixing tube to participate in the mass transfer process, and the liquid and gas are fully mixed. Then it is discharged into the aeration tank and causes strong turbulence and swirl in the tank to quickly increase the dissolved oxygen in the water. The device is a two-stage structure that absorbs air first and then absorbs water, with high aeration power efficiency and a large aeration range.
