HIGH EFFICIENCY/LOW PRESSURE CATALYTIC CRACKING SPRAY NOZZLE ASSEMBLY

摘要

A gas assisted liquid spray nozzle assembly having a nozzle body that defines a mixing zone, a liquid inlet communicating with the mixing zone from an end, and a pressurized gas inlet communicating with the mixing chamber from an upstream side. The liquid inlet includes a liquid injector extending into the nozzle body having a liquid inlet extension passage and a plurality of discharge orifices adjacent a closed downstream end which define an impingement surface for directing liquid into the mixing zone in transverse relation to a central axis of the mixing zone. The nozzle body and liquid injector define a plurality of concentrating gas discharge passages at respective locations of the injector liquid discharge orifices for causing individual pressurized gas to directly interact with transversely directed liquid into the mixing zone for enhanced atomization and ultimate discharge from a downstream spray tip.

1. A gas assisted liquid spray nozzle assembly comprising:
a nozzle body having a mixing zone that communicates with a barrel extension zone downstream of said mixing zone, a liquid inlet from which a pressurized liquid is directed into said mixing zone, a gas inlet from which pressurized gas is directed into said mixing zone, said liquid inlet including an elongated liquid injector extending into the mixing zone along a central axis of the mixing zone, said liquid injector having a liquid inlet extension passageway and a plurality of discharge orifices adjacent a downstream end of said extension passageway for directing liquid from said extension passageway into the mixing zone in transverse relation to the central axis of the mixing zone, said nozzle body having a gas passage communicating with said gas inlet for directing pressurized gas across said liquid injector discharge orifices for atomizing liquid discharging from said liquid injector discharge orifices and directing atomized liquid through said barrel zone, and a spray tip mounted at a downstream end of said barrel zone having a discharge orifice through which atomized liquid directed through said barrel zone is discharged in a predetermined spray pattern.
