Annular effervescent nozzle
A nozzle includes a housing having an inner chamber, a first opening connected to the inner chamber, and a second opening connected to the inner chamber, and a solid, partially conical, plug in the second opening, the solid plug configured to leave a slit around the plug connected to the inner chamber, and the plug extending beyond an end of the housing.
1 . A nozzle, comprising:
a first pipe having a first portion having a first diameter, and a second portion having a second diameter wider than the first diameter having a step between the first portion and the second portion;
an inner pipe, the inner pipe having a lower portion having a lower diameter and a channel portion having a channel diameter wider than the lower diameter, the channel portion resting on the step;
an inner chamber;
a primary air channel formed by the inner pipe separate from the inner chamber;
an inlet opening on a side of the first pipe, the inlet opening connected to the inner chamber;
a top opening connected to the inner chamber;
one or more angled channels in the inner chamber configured to cause water to swirl within the inner chamber; and
at least one air opening structured to cause air to flow from the portion of the primary air channel separate from the inner chamber into the inner chamber; and
a solid, partially conical, plug in the top opening, the solid plug configured to leave a slit around the plug connected to the inner chamber for an exiting airflow, and the plug extending beyond an end of the first pipe.
2 . The nozzle as claimed in claim 1 , wherein the nozzle further comprising an impactor arranged adjacent the solid plug.
3 . The nozzle as claimed in claim 2 , wherein the impactor surrounds the solid plug adjacent the slit.
4 . The nozzle as claimed in claim 2 , wherein the impactor resides a distance offset from the slit.
5 . The nozzle as claimed in claim 1 , further comprising an electrical charging element adjacent the plug.
6 . The nozzle as claimed in claim 5 , wherein the charging element further comprises a ring surrounding the solid plug adjacent the slit.
7 . The nozzle as claimed in claim 5 , wherein the charging element adjacent the plug comprises the charging element being separated from the nozzle.
8 . The nozzle as claimed in claim 5 , wherein the charging element has a dielectric coating.
9 . The nozzle as claimed in claim 8 , wherein the dielectric coating comprises one of titanium dioxide, barium titanate, or lead zirconate titanate (PZT).
10 . The nozzle as claimed in claim 1 , wherein the plug has a hydrophobic coating.
11 . The nozzle as claimed in claim 1 , wherein the plug comprises a hydrophobic material.
12 . The nozzle as claimed in claim 1 , wherein the at least one air opening comprises a plurality of air openings.
13 . The nozzle as claimed in claim 12 , wherein the plurality of air openings are angled.
14 . The nozzle as claimed in claim 1 , wherein the inlet opening is structured to cause water to flow into the inner chamber at an angle.
15 . The nozzle as claimed in claim 1 , further comprising an annular air channel surrounding the primary air channel, the annular air channel separate from the primary air channel.
16 . The nozzle as claimed in claim 1 , further comprising additional air channels placed so that the exiting airflow directs across a flow of droplets as the droplets exit the slit.
