DEVICE AND METHOD FOR BUBBLE SIZE CLASSIFICATION IN LIQUIDS |
摘要 |
The invention relates to a device and a method using said device for measuring and classifying the size of bubbles in a liquid medium. The invention comprises two electrical transducers, namely an emitting transducer and a receiving transducer, positioned at an angle of less than 180° in relation to one another, and an ultrasound signal-transmitting circuit and an ultrasound signal-receiving circuit which are functionally connected to the emitting and receiving electrical transducers respectively. The bubble size classification is based on two-dimensional templates in the time domain, which represent the trace of the bubbles when they cross a generated ultrasound field. The invention is particularly suitable for use in the monitoring of processes that involve the generation of bubbles in liquid media, such as flotation in mining. |
