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:
The present invention relates to a kind of aerator, especially for the jet aerator of wastewater treatment.
Background technology:
In water treatment field, the traditional blast aeration and the oxygen mass transfer coefficients of mechanical aeration, dissolved oxygen speed, mix shortcoming such as all undesirable and device structure complexity of mixing effect.The performance that the jet Aeration Technology and Its of recent development demonstrates at aspects such as oxygen transfer, dissolved oxygen speed, utilising efficiencys, but its oxygenation capacity is still undesirable.
Summary of the invention:
The object of the invention provides a kind of oxygen mass transfer coefficients height, dissolved oxygen speed is fast and mixing and stirring and the good a kind of jet aerator of oxidation effect.The present invention realizes that the technical scheme of goal of the invention is, a kind of jet aerator comprises inlet pipe, water jet, and the air water mixing section, trunnion section and expansion section Taper Pipe is characterized in that: the exit at the diffusing cone pipeline section is provided with wire netting.Described wire netting is the Stainless Steel Wire mesh grid.The tapering of described expansion section Taper Pipe is 29-32 °, and the length of expansion section Taper Pipe is 1:1 with the length of trunnion ratio.The present invention not only has the mass transfer coefficient height compared with the prior art, dissolved oxygen speed is fast and mixing and stirring but also the good remarkable advantage of oxidation effect.
Description of drawings:
Fig. 1 is the structural representation of jet aerator of the present invention.
Embodiment:
At the unfavorable shortcoming of existing jet aerator oxidation effect, through research and experiment, exit at the expansion section Taper Pipe of jet aerator is provided with net, and this net is the Stainless Steel Wire mesh grid, and the size of mesh is 5-8mm, the jet aerator of net is set through experiment, because this net carries out secondary cut with the bubble that ejects, bubble is littler, has increased gas-water contact area, therefore, its oxidation effect is improved.
In addition, in order further to improve oxidation effect, the tapering of the Taper Pipe of expansion section is preferably 29-32 °, and the length lengthening of expansion section Taper Pipe makes its length ratio with the trunnion section reach 1:1, and its oxidation effect is better.
Principle of work of the present invention is, pass through in the tapered tube of trunnion 3 at expansion section the deceleration step-down through the water of nozzle 4 ejection when passing through wire netting 1 at the bubble of air chamber and the gas of coming in from inlet pipe 5 mixes back generation and water, bubble further is divided into small bubbles, enlarge the contact area of water and gas, thereby oxidation effect further improves, about dynamic efficiency doubles.
