Research progress of microbubble generator

介绍了微气泡发生器的研究进展。微气泡的产生方法主要有溶气-释气法、微孔曝气法、引气-散气法、超声/声压法和电解法等。其中溶气-释气法产生的气泡分布窄,气泡数量多,但能耗高,流程复杂;微孔曝气法产生的气泡分布窄,气泡数量多,能耗低,但孔道易堵塞;引气-散气法产生的气泡数量多,能耗低,但气泡相对较大,气泡分布宽;超声/声压法产生的气泡分布窄,气泡数量少,但能耗高,对设备要求较高;电解法产生的气泡分布窄,气泡数量少,但能耗高,组分单一。可以针对具体的应用体系和应用要求,选择合适的微气泡发生器。

The research progress of microbubble generator is introduced.The generation methods of microbubbles mainly include pressurized dissolution method,membrane dispersion method,self-sucking method,ultrasonic method and electrolysis method.The bubbles distribution produced by the pressurized dissolution method is narrow and the number of bubbles is large,but the energy consumption is high and the process is complex.The membrane dispersion method produces narrow bubbles distribution,large number of bubbles and low energy consumption,but the pore channel is easy to be blocked.The self-sucking method produces a large number of bubbles and low energy consumption,but the bubbles are relatively large and the bubbles distribution is wide.The distribution of bubbles produced by ultrasonic method is narrow and the number of bubbles is small,but the energy consumption is high and the equipment requirements are high.The distribution of bubbles produced by electrolysis method is narrow and the number of bubbles is small,but the energy consumption is high and the components are single.The suitable microbubble generator can be selected according to the specific application system and application requirements.
