Ultrasonic Exposure of the Liquid Film for Highly Efficient Gas Absorption
Authors: , , ,
Abstract: A model of ultrasonic intensification of the absorption process is proposed, developed, and analyzed. For the first time, the model takes into account the effect of wave-like capillary perturbations of the liquid-gas surface and the acceleration of diffusion in the liquid volume on the absorption rate due to cavitation. According to the results of the model researches, the need for uniform sounding of the extended surface of the liquid film is established to accelerate the absorption of carbon dioxide and other harmful and target gaseous impurities by at least 3 times. The designs and layout of ultrasonic vibration radiators with an extended radiation surface are proposed. The results of measurements of the vibration amplitudes of the invented transducers showed that they have a relative deviation of the amplitude of no more than 0.2. The proposed approaches to the implementation of the process can be recommended for further research, the selection of optimal designs, and industrial applications to accelerate the absorption of gaseous impurities
