Mist generating apparatus

摘要

A mist generating apparatus is provided. The apparatus has a longitudinal axis and comprises first and second opposing surfaces which define a transport fluid nozzle between them. The apparatus also has a working fluid passage having a supply passage connectable to a supply of working fluid, and an outlet on one of the first and second surfaces. The working fluid outlet communicates with the transport fluid nozzle. The transport fluid nozzle has a nozzle inlet connectable to a supply of transport fluid, a nozzle outlet, and a throat portion intermediate the nozzle inlet and nozzle outlet. The nozzle throat has a cross sectional area which is less than that of either the nozzle inlet or the nozzle outlet. The transport fluid nozzle projects radially from the longitudinal axis such that the nozzle defines a rotational angle of at least 5 degrees about the longitudinal axis. A method of generating a mist using the apparatus is also provided.

1. A mist generating apparatus having a longitudinal axis and comprising:
first and second opposing surfaces which define a transport fluid nozzle therebetween; and a working fluid passage having an inlet connectable to a supply of working fluid, and an annular outlet on one of the first and second surfaces, the outlet communicating with the transport fluid nozzle; wherein the transport fluid nozzle has a nozzle inlet connectable to a supply of transport fluid, a nozzle outlet, and a throat portion intermediate the nozzle inlet and nozzle outlet, wherein the nozzle throat has a cross sectional area which is less than that of both the nozzle inlet or the nozzle outlet; wherein the nozzle outlet defines a slot on an external surface of the mist generating apparatus; wherein the working fluid outlet is substantially annular and concentric with the longitudinal axis; and wherein the transport fluid nozzle projects radially from the longitudinal axis such that the nozzle defines a rotational angle about the longitudinal axis so that a flow of transport fluid passes through the nozzle throat and accelerates the transport fluid to apply a shearing force to a working fluid in communication with the transport fluid nozzle from the working fluid outlet and atomises the working fluid to form a mist of vapour and working fluid droplets.
