Abstract

The utility model discloses a self-suction three-mixing-pipe two-stage jet flow aerating device. The device consists of a submerged pump, a self-suction three-mixing-pipe two-stage jet flow aerator and a pipeline system, wherein the self-suction three-mixing-pipe two-stage jet flow aerator comprises a nozzle, a throat pipe, an air suction pipe, an air suction chamber, a conical splitter, mixing pipes and a water suction pipe. According to the device, the submerged pump forms high-speed high-pressure water jet flow in the position of the nozzle; due to viscous action between a jet flow boundary layer and air, the air is sucked into the air suction chamber and is mixed with water jet flow preliminarily in the throat pipe; a liquid gas mixture is split and cut by the conical splitter and enters the three mixed pipes which are arranged radially; under the turbulent diffusion and carrying action of the liquid gas mixture, water in an aeration tank is sucked into the mixed pipes and takes part in the mass transfer process; and after liquid and gas are mixed completely, the mixture is discharged into the aeration tank and generates strong turbulence and rotational flow in the tank, so oxygen dissolution in water is improved quickly. The device is of a two-stage structure for firstly sucking air and then sucking water, so the oxygen-increasing power efficiency is high and the aeration range is large.
