LONG-RANGE NOZZLE FOR ENTRY OF AIR

Abstract

A long-range nozzle for introducing air into a room comprising a nozzle body (1) opening in a nozzle opening (13) is described. In order to enable an advantageous air moistening, it is proposed that the nozzle opening (13) is surrounded by a coaxial crown of atomizer nozzles (8) which are connected to an annular channel (9) to which pressurized liquid can be applied.

Claims

1. A long-range nozzle for introducing air into a room comprising a nozzle body (1) opening in a nozzle opening (13), comprising a crown of atomizer nozzles (8) coaxially surrounding the nozzle opening (13) which are connected to an annular channel (9) to which pressurized liquid can be applied.

2. The long-range nozzle according to claim 1, wherein the nozzle body (1) comprises a dome-shaped housing (2) which carries the crown of atomizer nozzles (8).

3. The long-range nozzle according to claim 1, wherein an annular guiding wall (14) is provided on the side of the atomizer nozzles (8) facing away from the nozzle opening (13).

4. The long-range nozzle according to claim 1, wherein the annular channel (9) with the atomizer nozzles (8) and optionally with the guiding wall (14) forms a structural unit (10) which can be placed on the dome-shaped housing (2).

Description

BRIEF DESCRIPTION OF THE DRAWING

[0011] The subject matter of the invention is shown as an example in the drawing and specifically a long-range nozzle according to the invention is shown in a schematic longitudinal section.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0012] According to the exemplary embodiment shown, the long-range nozzle according to the invention comprises a conventional nozzle body 1 with a dome-shaped housing 2 which is pivotably mounted about a pivot axis 3 in a pipe connecting piece 4. The pipe connecting piece 4 via which the long-range nozzle is connected to an air line, is inserted in a recess 5, indicated by a dot-dash line, of a wall or ceiling 6 delimiting a room to be ventilated. The pipe connecting piece 4 with the dome-shaped housing 2 mounted in the pipe connecting piece 4 is covered by a terminating ring 7 which overlaps the wall or ceiling 6.

[0013] Unlike conventional long-range nozzles of this type, the long-range nozzle according to the invention is provided with a crown of atomizer nozzles 8 coaxial to the nozzle body 1 which are connected to an annular channel 9 which can be acted upon with a pressurized liquid for moistening the air blown out into the room. The atomizer nozzles 8 with the annular channel 9 form a structural unit 10 which forms a ring 11 which can be placed on the dome-shaped housing 2. This ring 11 is firmly clamped onto the housing 2 with the aid of screws 12 and fluidically forms an extension of the nozzle opening 13 of the nozzle body 1. On the side of the atomizer nozzles 8 facing away from the nozzle opening 13, the ring 11 of the structural unit 10 forms a guiding wall 14.

[0014] In order to moisten the air flow 15 blown out into the room by the long-range nozzle, the atomizer nozzles 8 are acted upon with pressurized liquid so that a liquid mist 16 surrounding it is supplied to this air flow 15 from the atomizer nozzles 8 which is mixed internally with the air flow 15 emerging from the long-range nozzle and vaporizes during its conveyance with this air flow 15. As a result of the injector effect on the one hand of the air flow 15 blown out from the long-range nozzle and on the other hand of the liquid mist 16 ejected from the atomizer nozzles 8, room air 17 is additionally sucked in which surrounds the air flow 15 and the liquid mist 16 in the form of an air jacket and prevents liquid droplets of the liquid mist being separated from the air flow 15 before this liquid mist is vaporized.
