TWO-FLUID NOZZLE AND ATOMIZING DEVICE PROVIDED WITH TWO-FLUID NOZZLE

摘要

PROBLEM TO BE SOLVED: To provide a two-fluid nozzle capable of spraying liquid fine particles of a two-fluid mixture under a low pressure of a gas supply and an atomizing device for atomizing the liquid fine particles sprayed from the two-fluid nozzle.;SOLUTION: An outer orifice of an outer and an inner orifice of an inner nozzle are arranged in series at prescribed intervals (L1) so that the center axis of the outer orifice of the outer nozzle coincides or nearly coincides with the center axis of the inner orifice of the inner nozzle, and a second passage of a second fluid is formed between an outer nozzle inner wall surface and an inner nozzle outer wall surface so that the flow direction of the second fluid to be mixed with a first fluid forms an angle (α) with respect to the flow direction of the first fluid flowing from a first passage of the inner nozzle. The atomizing device is provided with a first atomizing part for atomizing the liquid fine particles sprayed from the two-fluid nozzle, an opening part communicating with the outside of the device body from the first atomizing part and a liquid supply part which is a supply source of the second fluid used in the two-fluid nozzle and is provided in the lower part of the device body.;COPYRIGHT: (C)2012,JPO&INPIT
