本文概要介绍了一种新型的浮选柱外部气泡发生器系统。它是在高压下将空气与水混合,然后通过一个细小喷嘴逸出气泡。在起泡剂用量很低的条件下,这种气泡发生器能够控制大范围气泡的大小,并且所发生的气泡在矿浆中保持的时间比传统的多孔气泡发生器的气泡保持的时间长得多。此外,该气泡发生器维修和校正时,浮选柱不需要停车。 This article outlines a new type of flotation column external bubble generator system. It mixes air with water under high pressure and then escapes through a tiny nozzle. This bubble generator is capable of controlling the size of a wide range of bubbles at very low levels of blowing agent, and the bubbles that occur are held in the slurry for much longer than the bubble retention of conventional porous bubble generators . In addition, the bubble generator does not require parking when it is repaired and calibrated.
