    A jet nozzle for introducing air into a room with a nozzle body (1) opening into a nozzle opening (13) is described. In order to enable advantageous humidification, it is proposed that the nozzle opening (13) is surrounded by a coaxial ring of atomizing nozzles (8), which are connected to an annular channel (9) which can be acted upon with hydraulic fluid.

    专利说明:

    The invention relates to a jet nozzle for air entry into a room with a nozzle body opening into a nozzle opening.
    Jet nozzles are used to introduce cold or hot air into rooms with a required penetration depth of the blown-out air stream, in order to supply particular voiced room areas with the introduced air. The orientation of the jet nozzles is therefore of considerable importance, which has led to pivotable nozzle bodies. For this purpose, it is known (EP 0 826 932 A2) to provide the substantially conical nozzle body with a dome-shaped housing, which is mounted in a tubular connecting piece on the one hand around the axis of the connecting piece and on the other hand pivotable about an axis perpendicular thereto, so that the projecting beyond the dome-shaped housing Nozzle orifice can be aligned as desired. If the air injected into the room is to have a predetermined moisture content, the air upstream of the jet nozzle must be conditioned accordingly, which is not only expensive, but usually precludes retrofitting with a humidifier.
    The invention is therefore based on the object to provide measures, with de¬ren help in a simple way a humidification of the spray nozzle jet is possible without having to fear a departure of non-vaporized liquid droplets from the blown into the room air flow.
    Based on a jet nozzle of the type described above, the invention solves the task by a coaxially surrounding the nozzle opening
    Wreath of atomizing nozzles, which are connected to a pressurized liquid ring channel.
    By means of the atomizer nozzles, a liquid mist which is mixed with the conveying air flow and evaporated can be fed to the jet of air blown out of the jet nozzle. In this connection, the injector action on the one hand of the long-throw nozzle and on the other side of the ring on atomizing nozzles causes the air jacket enveloping the liquid mist which flows annularly from the atomizer nozzles to effectively prevent the separation of liquid droplets from the air flow injected into the space, bevordie Liquid droplets are evaporated. The turbulences occurring in the mixing region on the one hand support a rapid distribution of the liquid droplets within the blown-out air flow and on the other hand increase the residence time of the liquid droplets in the air flow, so that even at a comparatively short distance from the long-throw nozzle a substantial evaporation of the atomizing nozzles arranged via the annular nozzle introduced Flüssig¬keitsnebel can be detected. The pressurization of the nebulizer nozzles sometimes with a predetermined pressure of standing liquid via an annular channel is structurally simple and allows a pressure control of the liquid to be atomized a good dosage of the amount of liquid to be supplied depending on the difference of the desired moisture and the moisture exiting from the long throw thru air. The number of atomizing nozzles in the nozzle ring plays a subordinate role, although with several atomizer nozzles a more rapid distribution of the moisture over the circumference of the air jet is achieved than, for example, with two atomizer nozzles. The liquid mist introduced into the air jet of the jet nozzle can also be used to cool the injected air flow, because this liquid mist extracts the heat of vaporization for its vaporization of the air.
    Particularly simple construction conditions arise when the nozzle body has a dome-shaped housing, which carries the ring of atomizer nozzle, because in this case no structural changes have to be made to the nozzle body itself and the dome-shaped housing offers sufficient space for receiving the nozzle ring and the annular channel for acting on the spray nozzles.
    In order to improve the flow conditions for the injector action sucked, the nozzle ring enveloping the air jacket, on the side facing away from the nozzle opening of the atomizer nozzles may be provided an annular guide wall, which largely dictates the flow conditions for this air jacket. If the atomizer nozzles are provided on a dome-shaped housing, a part of this housing can advantageously be used as a guide wall.
    If the annular channel with the atomizer nozzles and optionally with the guide wall forms a structural unit which can be placed on the dome-shaped housing, conventional jet nozzles with a dome-shaped housing can be equipped with a device according to the invention for air humidification via a nozzle ring in a simple manner, because the structural unit from the annular channel with the Zer¬stäuberdüsen and optionally with the baffle is zubefestigen only on the housing.
    The subject matter of the invention is shown by way of example in the drawing, namely a long-throw nozzle according to the invention is shown in a schematic longitudinal section.
    The jet nozzle according to the invention has, according to the illustrated Ausführungs¬beispiel a conventional nozzle body 1 with a dome-shaped Einhau¬sung 2, which is mounted pivotably about a pivot axis 3 in a pipe socket 4. The pipe socket 4, via which the long-throw nozzle is connected to an air line, is inserted into a recess 5 of a wall or ceiling 6 which delimits a room to be ventilated and indicated by dash-dotted lines. The pipe socket 4 with the dome-shaped housing 2 mounted in the pipe socket 4 is covered by a closing ring 7, which engages over the wall or ceiling 6.
    In contrast to conventional jet nozzles of this type, the jet nozzle according to the invention is provided with a ring coaxial with the nozzle body 1 of atomizing nozzles 8 which are connected to an annular channel 9 which can be charged with a pressurized liquid for humidifying the air blown into the room. The atomizer nozzles 8 with the annular channel 9 form an assembly 10 which forms a ring 11 which can be placed on the dome-shaped housing 2. This ring 11 is clamped to 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 atomizing nozzles 8 facing away from the nozzle opening 13, the ring 11 of the assembly 10 forms a guide wall 14.
    In order to humidify the airflow 15 blown through the jet nozzle into the space, pressurized liquid is applied to the atomizing nozzles 8, so that this airflow 15 is supplied with a liquid mist 16 enclosing it from the atomizing nozzles 8, which is in contact with the airflow 15 issuing from the jet nozzle intimately mixed and evaporated during its promotion with this Luftströ-mung 15. Due to the injector on the one hand, the blown out of the jet nozzle jet 15 and the other side of the spray nozzles 8 ejected liquid mist 16 room air 17 is additionally sucked, the air flow 15 and the liquid mist 16 in the form of an air jacket encloses and prevents liquid droplets of the liquid mist The air flow 15 are excreted before this liquid mist is vaporized.
