ABSTRACT:
The present invention provides a novel apparatus and process for generating a vapor spray from a volatile fluid. In the invention, the volatile fluid is heated to a temperature just below its boiling point prior to being discharged from heat exchanger (18, 46). In one embodiment of the apparatus, heat exchanger (46) contains a diffusion plate (48) to ensure that the volatile fluid is at the selected temperature when discharged from the heat exchanger. In this embodiment, the apparatus further includes a pressure-responsive valve (40) and a bypass line (42) so that a selected pressure is maintained downstream from pump (34).
The novel process of the present invention includes the step of heating the volatile fluid within heat exchanger (18, 46) to a selected temperature just below its boiling point prior to discharge from the heat exchanger. In one embodiment, the process further includes the step of impinging the volatile fluid stream as it enters heat exchanger (46) onto diffusion plate (48) so that it is ensured that the volatile fluid is at the selected temperature upon discharge. In this embodiment, passing of the fluid drawn from reservoir (32) is accompanied by modulating the flow of the drawn fluid through bypass line (42) connecting pump (34) and reservoir (32), whereby a selected pressure is maintained downstream from pump (34).
