A mist-generating apparatus and method

摘要

A mist generating apparatus is provided, the apparatus comprising a nozzle having a nozzle inlet (54) connectable to a source of driving fluid, a nozzle outlet (58), and a nozzle throat (56) intermediate the nozzle inlet (54) and nozzle outlet (58), the nozzle throat (56) having a cross sectional area which is less than that of both the nozzle inlet (54) and nozzle outlet (58). The apparatus also comprises at least one process fluid passage (32) having an inlet connectable to a source of process fluid and an outlet (34) which opens into the nozzle. A perforated member (46) is located across the process fluid passage outlet (34) to assist the apparatus in atomising the process fluid. Methods of generating a mist and assembling the apparatus are also provided.
