| 摘要 |
A starting solution is evaporated to produce an end solution by spraying the starting solution into a gaseous medium under certain conditions. The starting solution is supplied by delivering means (18,24) using a pump (16) to spray head members (53), each having a plurality of holes (56) for producing droplets of substantially constant radius substantially independent of operating pressure. The spray head members (53) are connected to at least one starting solution supply conduit (24) substantially at its surface and are purged from foreign material with starting solution in the supply conduit (24). A similar method and apparatus for cooling a liquid are also disclosed. |
