Embodiment Construction

[0005] Aiming at the shortcomings of the unsatisfactory oxygenation effect of the existing jet aerator, after research and experiments, a net is set at the outlet of the cone tube in the diffusion section of the jet aerator. The net is a stainless steel wire woven net with a mesh size of 5 -8mm, the jet aerator with the net set up through the experiment, because the net cuts the ejected air bubbles twice, the air bubbles are smaller, and the air-water contact area is increased, so the oxygenation effect is improved.

[0006] In addition, in order to further improve the oxygenation effect, the taper of the conical tube in the diffusion section is preferably 29-32°, and the length of the conical tube in the diffusion section is lengthened so that the ratio of the length of the conical tube to the throat section reaches 1:1, and the oxygenation effect is better .

[0007] The working principle of the present invention is that the air bubbles and water produced after the water spr...

Abstract

The invention discloses a jet flow aerator, relating to an aerator and aiming to provide a jet flow aerator with high mass transfer coefficient, high dissolved oxygen speed, uniform mixing stirring and favorable oxygenated effect. The jet flow aerator comprises an air inlet pipe, a water spray nozzle, a gas-water mixing chamber, a throat section and diffusion section taper pipe, and a metal net is arranged at an outlet of a diffusion taper pipe section. The invention is used for wastewater treatment.

Description

Technical field: [0001] The invention relates to an aerator, in particular to a jet aerator for wastewater treatment. Background technique: [0002] In the field of water treatment, the oxygen mass transfer coefficient, dissolved oxygen speed, and mixing effect of traditional blast aeration and mechanical aeration are not ideal, and the equipment structure is complicated. The recently developed jet aeration technology has shown good performance in terms of oxygen mass transfer, dissolved oxygen rate, and utilization efficiency, but its oxygenation performance is not ideal. Invention content: [0003] The purpose of the present invention is to provide a jet aerator with high oxygen mass transfer coefficient, fast oxygen dissolving speed, uniform mixing and stirring and good oxygenation effect. The technical solution for the present invention to realize the purpose of the invention is that a jet aerator includes an air inlet pipe, a water spray nozzle, an air-water ...
