  • Multiphase mixing apparatus using acoustic resonance
    Patent number: 6283626
    Abstract: A multiphase mixing apparatus using acoustic resonance. The apparatus can induce a pressure difference between fluids to be mixed so that a resonance and an acoustic energy are generated, thereby shattering the fluids and effectively mixing them. The shattered gas fluid penetrating into the liquid fluid goes along a swirl flow so that the gas fluid stays in the liquid fluid for a relatively long time. In addition, the acoustic energy perturbs the fluids, a mass transfer resistance decreases.

  • Mixing apparatus using acoustic resonance
    Patent number: 5836683
    Abstract: A mixing apparatus is used in mixing two fluids, such as two liquids, a liquid and a solid, or a liquid and a gas, within beer fermenter, microorganism culture mediums, waste water disposal plants, and other chemical processes. It is high in efficiency and simple in maintenance and repair. In particular, this apparatus utilizes sound vibration which sends pulses through the apparatus and adds a fluid to the other fluid to be mixed. Therefore, the mixing efficiency level can be raised by using this fluid mixing apparatus.
