Embodiment
Show among the figure that the utility model is by reactor 3, slurry tank 4, frequency converter tube 10 is formed.
In cylindrical reactor 3 inside a jet frequency converter tube 10 is set, frequency converter tube 10 passes interference plate 11, the dead in line of the axis of frequency converter tube 10 and reactor 3.An ejector nozzle 12 is installed in the lower end of frequency converter tube 3, and the injector of ejector nozzle 12 and reactor 3 outsides 13 is connected by liquid-inlet pipe, and injector 13 is connected with high-pressure hydraulic pump.
The number that is installed in high-frequency transducer 16 on the plane reflection plate 14 and low-frequency transducer 15 is 2-4, and the ultrasonic frequency scope is 2MHZ-20KHZ.
The internal diameter of frequency converter tube 10 is greater than low-frequency transducer 15 wavelength X; The internal diameter of reactor 3 is the integral multiple of low-frequency transducer 15 wavelength X/2; Diffraction circular hole aperture on the interference plate 11 is less than the highest frequency wavelength X, and the circular hole between centers is λ/4.
Working process of the present utility model is as follows:
With high-pressure hydraulic pump sewage is squeezed into injector 13, after injector 13 sucked ozone, the liquid of gas-liquid mixed was injected in the frequency converter tube 10 through ejector nozzle 12, and its jet speed can reach the hundreds of rice of per second.Effluent stream also is subjected to hyperacoustic radiation effect in the time of frequency converter tube 10, according to the principle of Doppler effect, and the sewage in the frequency converter tube 10, speed realizes even frequency-conversion processing sewage by slack-off soon, suffered ultrasonic frequency also from high to low when flowing in sound field.
Sewage has very high kinetic energy when frequency converter tube 10 ejects, when sewage bump pyramid type pod 8, make sewage atomize, and the more little reaction with ozone, air of drop is abundant more, and the aeration effect is good more, and processing efficiency is high more.
The high velocity flow that ejector nozzle 12 penetrates makes local decompression district of 10 times interruption-formings of frequency converter tube, causes the sewage backflow in reactor 3, the slurry tank 4, has finished the repeated treatments process to sewage; Also played simultaneously good stirring action, made that reaction is more abundant.
Zone under interference plate 11, nearer apart from high-frequency transducer, low-frequency transducer, effect that sewage is handled in this zone is best.Middle and upper part at reactor 3, ultrasonic energy from bottom to top, outwards successively decreased by the center, because the diffraction of diffraction circular hole on the interference plate 11, the ultrasonic wave of reactor 3 middle and upper parts is interfered, not only amplitude becomes big, help cavitation effect and further strengthen, but also make that the cavitation face is more even.
After reactor 3 processing, liquid flows into the slurry tanks 4 from overflow port 5, and through sedimentation, supernatant liquid flows out from water outlet 6, and the turbid liquid of lower floor is by continuing processing in refluxing opening 2 Returning reactors 3.
Foregoing description only proposes as the enforceable technical scheme of a kind of ultrasonic wave sewage treatment unit of the utility model, not as the single restricted condition to its structure itself.
