Abstract:
The invention relates to an atomizer nozzle (10) with a liquid channel (19) which communicates downstream with an annular mixing chamber (26). A liquid (F) is supplied to the liquid channel (19) via a liquid connection (12). The atomizer nozzle (10) additionally has a gas connection (13) which is connected to a gas line system (28). Pressurized gas (L) is conducted to an outer injection channel (29) and an inner injection channel (34) via the gas line system. Each of the two injection channels (29, 34) opens into the annular mixing chamber (26) at a respective injection point (30, 35). The outer injection point (30) is provided on a radially outer mixing chamber wall, and the inner injection point (35) is provided on a radially inner mixing chamber wall. The inflowing liquid can thus be finely atomized using little pressurized gas (L) in the annular mixing chamber (26) and dispensed downstream of the annular mixing chamber via at least one outlet opening (40) in the form of a spray jet (S).

Abstract:
A liquid spray device prevents diffusion of a poisonous gas and odor in a sprayed liquid. A base includes an ejection orifice for ejecting acidic water, first and second feed paths communicating with ejection and spray orifices to feed acidic and alkaline water, respectively. The second feed path is open so that its front end continuously makes a circuit on the side surface of the base. A rotary part is disposed to rotate along the side surface of the base. The rotary part includes the spray orifices disposed to surround the periphery of the ejection orifice. The rotary part includes communication paths communicating with the respective spray orifices and the second feed path. The respective spray orifices spray alkaline water while rotating around the periphery of the ejection orifice to surround the periphery of acidic water ejected from the ejection orifice with the alkaline water in a curtain-like manner.

Abstract:
A nozzle for discharging first and second fluids in a spray pattern into a vessel, such as oil and steam in a catalytic cracking unit, includes various configurations for preventing erosion of the outlet portion of the nozzle that otherwise might be due, for example, to contact with a catalyst or other predetermined substance. In one such nozzle, the exterior surface of the outlet portion substantially conforms to the internal contour of the vessel. In another such nozzle, the outlet portion defines a plurality of substantially concentric, substantially elliptical-shaped outlet apertures. In another nozzle, the outlet portion is formed of ceramic and is connected to the inlet portion by a metal connector. In another nozzle, the outlet portion defines a plurality of apertures angularly spaced about a peripheral region of the outlet portion for discharging a substantially flat fan spray pattern, and a second outlet portion extending along an upstream portion of the outlet portion for discharging at least part of its spray to prevent any catalyst from contacting the downstream surfaces of the outlet portion.
