FLOW-AMPLIFYING LIQUID-ATOMIZING NOZZLE

摘要

FLOW-AMPLIFYING LIQUID-ATOMIZING NOZZLE A liquid-atomizing nozzle in which intermixing of air and liquid occurs externally of the nozzle and the primary air utilized for such intermixing is amplified by the entrainment of ambient secondary air. Two versions of the nozzle are disclosed, each having a tubular body with a generally cylindrical section terminating in a conical nose section. Air under pressure is discharged through radial openings in the cylindrical section and is redirected by a collar surrounding the cylindrical section to form a high velocity stream of air about and along the gradually-tapered outer surface of the nose section. Such high velocity primary air, amplified by ambient secondary air, strips liquid from at least one opening in the nose section to produce an externallydeveloped air-liquid mixture. In one version the liquid discharge opening is at the tip of the conical nose section; in another version a plurality of such openings are formed in the conical surface of that section.
