The characteristics such as in the utility model, parts adopt the PP material to make, and have good antiseptic property, and quality is light, and is durable in use.
Working process of the present utility model is: high pressure waste water is entered by the water inlet pipe of bottom, evenly enters each integrated jet pipe, through the strong eddy current of wortex device generation of its ingress, during eddy current process trunnion, because high-velocity jet forms negative pressuren zone at the trunnion end; Air with pressure enters air chamber by inlet pipe, by the production well of air chamber and the ejector inlet mouth at trunnion place, imported in integrated jet pipe, namely at the negative pressuren zone air water, fully contact, under the eddy current state, fully mix, dissolve in, then enter mixing tube and continue to mix, dissolve and diffusion, reach the purpose that increases dissolved oxygen efficiency.In addition, because integrated jet pipe and cylindrical shell are 60 ° of angles, at the bottom of causing air-water mixture by integrated jet pipe ejection to rush at aeration tank, fully stir the pond bottom sediment, both avoid the deposition of dead angle mud at the bottom of pond, increased again the stroke of microbubble in water, be conducive to improve dissolved oxygen efficiency.
The utility model passes through traditional Venturi tube, be improved to integrated jet pipe, when high pressure waste water process wortex device, can produce strong eddy current, negative pressure due to generation at a high speed during through trunnion sucks a large amount of air from air chamber, under the eddy current state, greatly improve the contact area of gas and waste water, increased dissolved oxygen efficiency; Integrated jet pipe is different from traditional jet pipe on the other hand, and mixing tube, trunnion are synthesized to an integral body, during the processing injection moulding, guarantees that precision is consistent, has not only improved the homogeneity of aeration, can also reach mixing comparatively fully of air water.
Owing to having adopted above technical scheme, the utility model is compared with currently available products, has following beneficial effect:
1), the utility model device all made by the PP material, and good antiseptic property is arranged, quality is light, and is durable in use, the life-span extends greatly;
2), integrated jet pipe and cylindrical shell be 60 ° of angles, prevents that place, dead angle, bottom, aeration tank from existing and the deposition of mud, increased utilization ratio and the dissolved oxygen efficiency of aeration tank;
3), wortex device is set in integrated jet pipe, form strong eddy current, increased the gas-to-liquid contact area, improved dissolved oxygen efficiency, save energy consumption;
4), trunnion, mixing tube once-forming in integrated jet pipe, guaranteed precision, improved the homogeneity of aeration;
