    The present invention relates to an air diffuser using a rotational force and acoustic resonance, and in particular, in the oxygen supply device of a wastewater treatment plant, the rotational force and sound to improve oxygen transfer efficiency by increasing the solubility of oxygen by using the acoustic energy due to rotational vortex and resonance. The present invention relates to an air diffuser using resonance.
    The conventional air diffuser is composed of a connector body 1, a fixing table 2 and a pipe 3, as shown in FIGS. 1 and 2, so that air entering the connector body 1 As it passes through the micropores, it is formed into small bubbles and supplied into the water. At this time, the pipe (3) is not made of a separate hole, but when the pipe is made using a ceramic or polyethylene (P. E.) is to be produced in advance to create a fine hole. However, this device is a device that simply reduces the size of the air bubbles by passing through the micro holes, and there is a limit to reducing the size of the air bubbles. It also requires less airflow.
    Another conventional technique is to break the air shroud 7 into small air bubbles while passing through the air inlet 5 and the net 6 through the air inlet 4 and the air inlet 4 as shown in FIGS. 3 and 4. There is a device that is supplied to the water through. However, in this apparatus, there is a limit in making the hole of the air shroud 7 small, so that large air bubbles are released into the water and the efficiency thereof is very low.
    Accordingly, an object of the present invention is to break the gas droplets by using the energy generated by the rotational vortex of the air and acoustic resonance to solve the above problems, and to increase the solubility of the gas, especially oxygen, to increase the oxygen transfer efficiency. It is done.
    The present invention is a cylindrical body of which the bottom is sealed and the inside is empty in order to achieve the above object, the inner column formed so that the inner space is annular at the center of the bottom surface, the outside air on the side of the body of the inner space It characterized in that it has an inlet hydraulically in the tangential direction.
    The acid generator according to the present invention can be used anywhere in the art for dissolving gas into a liquid, and preferably can be used as a supply device of oxygen in a wastewater treatment apparatus.
    Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.
    5 is a front sectional view of the air diffuser according to the present invention, when air enters the tangential inlet 9 made of the main body 8, the vortex is formed and exits to the outlet 10. FIG. At this time, since the air introduced from the inlet (9) rotates in a tangential direction in the inner column (11) in the main body (8), the pressure in the center of the inner column is relatively low and the pressure is lowered toward the outside. Therefore, water flows from the center of the air outlet 10 of the main body, which is relatively low in pressure, into the inner column 11 in the main body 8, and the inflowed water is encircled by the rotating gas to perform a circular motion. By the centrifugal force of the circular motion, the water is discharged while the gas is split into the water while forming a rotational vortex with the gas rising while rotating from the lower portion of the main body while going out of the main body. When released into the water, resonance occurs at a frequency (F) due to the pressure difference between the water flowing into the main body and the water / gas released into the main body, and the acoustic energy is transferred to the water while air bubbles It reduces the mass transfer resistance from water to water and speeds up the dissolution of gas and oxygen. In addition, due to the resonance, the gas bubbles in the water rise while moving horizontally without vertical rise, thereby increasing the residence time of the gas in water, allowing more gas to be dissolved.
    The resonance frequency is as follows.

    Here, the magnitude and frequency of the acoustic resonance are the coefficients (K) associated with the reduction of the rotational speed of air due to friction in the chamber, the diameter of the lower part of the chamber (d1), the height (h) extending perpendicularly from the diameter of the lower part of the chamber, It depends on the pressure P air and the water pressure P water at the outlet of the radiator. In addition, in the present invention, C is a sound speed, and in the present invention, the speed of sound in a medium in which gas and water are mixed, or close to the speed of sound in the air (340 m / s) because gas occupies most of the medium under actual operating conditions of an air diffuser. . The coefficient K is also measured experimentally in accordance with the diffuser.
    According to the experiments of the present inventors, the height (h) extending vertically from the diameter of the main body is 30mm, the upper diameter (d1) of the main body is 20mm, the diameter (d2) of the main body is 30mm, the diameter of the inlet (d3) Is 6mm and the flow rate is 100-500ℓ / mn, and the oxygen transfer efficiency is improved by more than 15% compared to the conventional diffuser by splitting the gas droplets small by the vortex of air and acoustic energy by resonance and increasing the solubility of oxygen. Can be obtained. In addition, tapering the shape of the inner column reduces the resistance when water enters the main body, thereby improving the oxygen transfer efficiency.
    At this time, the oxygen transfer efficiency is as follows.

    FIG. 6 is a cross-sectional view AA ′ of the diffuser shown in FIG. 5, where air enters a tangential inlet 9 in the main body 8 and a vortex is formed and the vortex formed is an outlet ( It shows exiting to 10).
    The present invention increases the oxygen transfer efficiency by breaking the air bubbles into small pieces and increasing the solubility of oxygen using energy generated by the rotational vortex of air and acoustic resonance. In addition, the same amount of dissolved oxygen can be obtained even by supplying a small amount of air, which saves the operating cost of the oxygen supply device, and its simple structure makes it easy to manufacture and the hassle of having to clean frequently due to the propagation of aquatic plants. I can solve it.
