Problems solved by technology

[0003] However, the design of this type of jet aerator is relatively complicated. Improper design can easily lead to small air intake, poor quality of bubbles, low power efficiency, and affect the cost of water treatment. This has become the main "bottleneck" of the engineering promotion and application of this type of jet aerator "
At the same time, since the basic structure of this type of jet aerator was proposed, the research on the new type of jet aerator, especially the outflow mode and outflow parts, and the optimization design of the structural parameters of the jet aerator have not attracted enough attention in recent years. Attention, there are relatively few researches and applications on this equipment
The most common is the direct discharge of the tailpipe, which is si...

Embodiment Construction

[0025] The research on the water distributor is an innovative point, and the name of the water distributor is generally called by the researchers according to its function. Its main function is to balance the contradiction between suction performance and agitation performance, promote the oblique and uniform flow of the three-phase mixed liquid, increase the agitation range of the jet aerator, and transfer the input energy to a wider water body, so as to achieve The purpose of rational utilization of input energy and energy saving.

[0026] Specific working conditions: the water distributor 6 is installed at the rear of the tailpipe 5 and is connected by a flange, which is convenient for disassembly and maintenance. When working, when the gas-liquid foam flow enters the water distributor 6 through the tail pipe 5, because the internal design is equipped with a cone 10 with a certain angle, the flow of the mixed liquid will be deflected and flow from the water distributor at a ...

Abstract

The invention discloses a split jet aerator, which comprises the following parts: suction inlet, water nozzle, mixing tube, dispersing pipe, tail pipe and distributor, wherein the distributor connects the tail pipe; a cone with the action of deflecting the composite liquid and reducing the local resistance is set in the pipe segment with diffusing angle of tail pipe; the CFD company adopts artificial software value to optimize the design of the structure of jet aerator, which transmits the composite liquid of effluent-living sludge into water nozzle; certain vacuum is formed in the course of jet to form three-phased composite liquid of gas, liquid and solid, which enters into the dispersing pipe to form jet distributor with certain pressure to do inclined ejection to aerate oxygen and stir. The invention improves more dynamic efficiency and more oxygen utility than traditional one, which possesses larger suction quantity, higher bubble quality, evener stirring power and more energy saving.

Description

technical field [0001] The invention belongs to the field of water treatment and relates to an aeration device. Background technique [0002] Jet aeration (self-priming) is used in small wastewater and industrial wastewater treatment projects. Compared with microporous aerators, it has low investment, no need to install fans and air purification, good agitation effect, high oxygen utilization rate, and is not easy to block. It has the advantages of convenient maintenance, low noise and convenient installation. [0003] However, the design of this type of jet aerator is relatively complicated. Improper design can easily lead to small air intake, poor quality of bubbles, low power efficiency, and affect the cost of water treatment. This has become the main "bottleneck" of the engineering promotion and application of this type of jet aerator ". At the same time, since the basic structure of this type of jet aerator was proposed, the research on the new type of jet aerator, es...
