    专利说明:

    The invention relates to a sputtering apparatus having a cleaning section for receiving a liquid and at least one nebulizer for sputtering the liquid into liquid droplets and an outlet opening for the exit of the thus generated liquid vapor or mist from the sputtering chamber.
    For the purpose of killing dangerous particles, such as viruses, spores, bacteria, etc. in rooms or for surface and surface disinfection, the liquid vapor or mist emitted by such a known atomizing device is allowed to act in a room or environment. It is e.g. dispersing a liquid suitable for disinfection in the form of droplets as aerosol uniformly in the ambient air, whereby it can be dispersed in the air and on surfaces e.g. meets infectious particles, which are rendered harmless by the disinfecting action of the liquid.
    A disadvantage has hitherto been the droplet size and the size distribution proved that are very difficult to control by conventional atomization devices. In the sputtering process by ultrasonic transducers occur in addition to small droplets and larger, which cause a relatively high precipitation on surfaces, which is undesirable because it gives rise to moisture, which can be disadvantageous in many ways. Sensitive surfaces can be destroyed or a corrosion process on valuable objects or instruments can be initiated.
    The smaller the droplet size can be maintained, the less moisture or liquid precipitate arises in the environment in which the atomizing device is to act.
    The object of the invention is therefore to provide a sputtering device of the type mentioned, with the aid of a liquid mist with the smallest possible droplet diameter can be discharged into the environment. ··· * · ,, ·,:. ···· ·· ·····
    According to the invention, this is achieved by providing at least one device for deflecting the liquid vapor or vapor, which is arranged in the region above the liquid surface.
    At this deflection device, a precipitate of droplets of larger diameter is formed, whereby a liquid mist with significantly smaller droplets remains.
    In this way, the average diameter of the liquid droplets can be reduced to less than 1 μητι, so that a very dry perceived liquid mist is formed, which is therefore hereinafter referred to as dry steam, which does not form a moisture film on the surfaces to be treated, the mold to mold. or rusting could result.
    In contrast to conventional steam-based devices, however, the liquid does not have to be heated when the dry steam is generated.
    In a further embodiment of the invention, the at least one device for deflecting the liquid vapor or mist can be formed by a turbulence shield arranged above the liquid level in the interior of the atomization chamber, at which larger liquid droplets form a precipitate and can run off or drip off.
    In order to achieve a very efficient removal of larger droplets, according to a further embodiment of the invention, the turbulence shield may have a horizontal wall section and a wall section inclined thereto towards the liquid surface, the inclined wall section being particularly inclined to direct the generated dry steam in the direction To redirect to the outlet and at the same time to allow the separation of the larger droplets, with deposited droplets, for example flow back into a tub or drip, in which the liquid is absorbed. -2-
    · · ·· ......
    In particular, according to a further embodiment of the invention, if the inclined wall section extends above the at least one nebulizer located in the bottom area of the sputtering chamber, this allows a particularly strong reduction in the proportion of large droplet diameters in the generated dry steam.
    It has been found to be particularly preferred when the inclined wall portion is inclined relative to the horizontal by the angle ß1, wherein ß1 is in a range of 10 ° to 45 °.
    In order to dissipate the freed of the larger droplets of liquid mist, a draft flow is set, which sets the resulting aerosol in motion.
    For this purpose, according to a further embodiment of the invention, an opening is formed in the sputtering chamber, through which an air stream can be passed over the liquid surface.
    Advantageously, it may be provided that the free end of the projecting into the Zerstäubungskammer Turbulenzschilds is arranged to form an opening cross-section at a distance from a side wall of the sputtering, so that the sputtering chamber is divided except for the opening cross-section in an upper and a lower region.
    Furthermore, a pressure device can be arranged in the upper area of the atomization chamber, via which pressure is increased within the atomization chamber in order to create an air flow.
    In a further embodiment of the invention, the printing device may be formed by at least one fan, is blown through the air from the environment in the Zerstäubungskammer, whereby an air flow through the opening cross section through -3- ,, ·· ···· ····· :: ·: ': = ··. is generated, which moves the liquid vapor rising from the liquid or mist in the direction of the outlet opening.
    According to a further embodiment, the outlet opening may be formed at one end of an outlet box having a rectangular tube cross-section which extends upwards. Through this outlet box of the larger droplet diameters freed liquid mist is discharged into the environment. However, instead of the rectangular tube cross-section another, e.g. a circular be provided.
    Another fluidic measure for reducing the proportion of liquid droplets with a large diameter can be formed in that a Beschieunigungsprisma is formed in the region of the outlet opening, which protrudes beyond the liquid level.
    Most preferably, the prism acceleration may be formed of two legs in the form of a reverse V-section, wherein the legs are inclined at an angle 51 relative to the vertical.
    In order to allow a further removal of droplets with a larger diameter from the liquid mist, it can be provided that the acceleration prism with its legs facing the outlet opening forms a cross-sectional constriction with the width a1 of the sputtering chamber.
    Finally, an increase in the exit velocity of the liquid mist is ensured by the fact that, according to a development of the invention, a rectangular hollow flow profile is arranged on at least one side of the outlet box, whose lower end is connected to the upper region of the atomization chamber, so that a partial flow of the pressure device is directed through the hollow flow profile becomes. -4- * · ··· «« · * ♦ ·· • * • ·

    6 shows a section AA through the view according to Figure 5;
    7 shows an enlarged view of the detail B from FIG. 6 and FIG. 8 shows an oblique view of the embodiment according to FIG.
    Figures 1 to 4 show an embodiment of a sputtering device according to the invention, with the aid of which a liquid can be atomized and released into the environment in the form of liquid droplets, in order, e.g. to decontaminate or sanitize a room by liquid droplets destroying airborne or surface-adhering particles in a way that will render them ineffective to humans or animals, thereby preventing them from infesting and degrading cells. But it can also be e.g. Food or computer keyboards are released from dangerous germs or other particles in which they are exposed to the output from the atomizing device according to the invention liquid mist or vapor.
    Regardless of the nature of these particles, e.g. Viruses, fungi, bacteria, etc., the atomizer emits a steady stream of droplets of liquid, which distribute accordingly and exert their disinfecting effect. As the liquid to be atomized, e.g. Hydrogen peroxide, but it can also be -5- «* ·· ···· other liquids or mixtures of liquids or pure water are sprayed, which has no disinfecting effect.
    The sputtering device shown in FIGS. 1 to 4 is surrounded by a housing 180 and has in its interior two sputtering chambers 1, 2 for receiving the liquid, which sputtering chambers 1, 2 are constructed mirror-symmetrically to the median plane, as shown in Figure 2 can be seen. However, just one or more than two sputtering chambers could just as well be provided without this having any influence on the mode of operation of the sputtering device.
    In operation, the two sputtering chambers 1, 2 are filled to a predeterminable liquid level with liquid. For this purpose, the bottom portion of the sputtering chambers 1,2 has a trough-like shape. As soon as the level falls below a certain level, a refilling process is required.
    In the sputtering chambers 1, 2, a multiplicity of nebulisers 3, 4 (FIG. 4) arranged side by side are provided parallel to the longitudinal axis of the sputtering apparatus and are provided e.g. in the example shown are designed as Ultraschallvernebler. However, within the scope of the invention, another type of atomization, e.g. electrostatic type are applied.
    The nebulizers 3, 4, e.g. can be designed as piezoelectric elements, are so embedded in the bottom of the sputtering chambers 1, 2 that they come with their Schwingkörpem with the liquid in contact and put them in vibration. In this way, a sputtering process takes place in which small droplets are released from the liquid surface, which are thrown upwards, whereby an aerosol is formed.
    For better operation of the nebulizer 3,4, a sound-reflecting cone 19 is formed between each of these and the chamber bottom, with which the -6- # ··
    19 can also be omitted.
    As cone angle φ1 (FIG. 3), an angle in the range of 15 ° to 80 ° has been found to be particularly preferred, but other angle values can also be used.
    The resulting dry steam passes through an outlet opening 30, which is formed at a lower end of an outlet box 70, which is divided in the embodiment shown in Figure 1 to 4 in two sub-boxes, with a rectangular tube cross-section which extends upward.
    According to the invention a device for deflecting the liquid vapor or mist 5 is provided, which is arranged in the region above the liquid surface.
    In the exemplary embodiment shown, the device for deflecting the liquid vapor or mist 5 is formed by a turbulence shield 50 which is arranged above the liquid level in the interior of the atomization chambers 1, 2 and has a horizontal wall section 6 and a wall section 7 adjoining the same in the direction of the liquid surface having. But it can also be provided a different type of deflection.
    The inclined wall portion 7 extends above the nebulizers 3, 4, which are arranged in the bottom region of the sputtering chamber 1, 2, and is inclined relative to the horizontal by the angle ß1, wherein ß1 is in a range of 10 ° to 45 °. In FIGS. 2 and 3, the angle β1 is selected to be 40 °.
    From the liquid surface ascending dry steam is deflected by the inclined wall portion 7 in the direction of the outlet opening 30. In this case, larger drops stick to the underside of the inclined wall portion 7 and run down along the inclined wall portion 7 in the direction of -7- * *! ► · *! I I · it ♦ * ··· * ·· *. ··· · _ ··· ·· #
    Liquid off. The remaining mist thus contains significantly fewer droplets with large diameter, so that can be spoken of a dry steam.
    The free end of the turbulence shield 50 projecting into the sputtering chambers 1, 2 is arranged at a distance from a side wall 93 of the sputtering chambers 1, 2 so that the sputtering chambers 1, 2 except for the opening cross-section 40 into an upper and a lower Area are divided. In the upper region of the Zerstäubungskammem each a pressing device 80 is arranged, via which during operation within the Zerstäubungskammern 1,2, the pressure can be increased.
    The pressure device 80 is formed by one or more fans 81 through which air is blown from the environment into the sputtering chamber, whereby an air flow is generated through the opening cross-section 40, which in the direction of liquid vapor or mist rising from the liquid moved to the outlet opening 30.
    In the region of the outlet opening 30, an acceleration prism 45 is formed, which projects beyond the liquid level and which is formed of two legs 46,47 in the form of an inverted V-section, wherein the legs 46,47 at an angle 51 relative to the central axis or the Vertical are inclined. The angle 51 may be in a preferred range of 0 ° to 60 °.
    Atomized liquid droplets of larger diameter also form a precipitate at this acceleration prism 45, while the finer droplets reach the outlet opening 30 via this acceleration prism 45. At the same time, the acceleration prism 45 forms, with its leg 47 facing the outlet opening 30 and the lower end of the outlet box 70, a tapered cross-sectional constriction with the width a1 at the lower edge of the outlet box 70. The outlet opening 30 is arranged approximately at half the height of the acceleration prism 45. The cross-sectional constriction width a1 -8- * * * * * *· * * ♦ may preferably be selected within a range of 1 mm to 15 mm, but may also be dimensioned differently. Also, the structure of the acceleration prism 45 may be designed differently in the context of the invention, this may also be formed without support on the pelvic floor.
    Overall, thus the atomized liquid droplets are moved under the action of the air flow generated by the pressure device (arrow 110) as an aerosol stream (arrow 111) in the direction of the outlet opening 30 and pass through them into the outlet box 70, and through this to the upper end of the outlet box 70 (arrow 113), where an outflow opening 71 is formed, from which the dry steam is discharged to the environment.
    The lower end of the outlet box 70 can also be widened, as indicated by the angle a1, which is 0 ° in the illustrated embodiment. As preferred, a1 has been found in a range of 0 ° to 45 °.
    As an additional measure, in order to accelerate the escape of the liquid mist from the outflow opening 71, rectangular flow hollow profiles 73 are arranged on both longitudinal sides of the outlet box 70, whose lower end is respectively connected to the upper region of the Zerstäubungskammem 1, 2, so through the flow hollow profile 73 a Partial flow (arrow 112) of the pressure device 80 is introduced and passed therethrough (arrow 114) in order to create a suction effect at the outflow opening 71 of the outlet box 70, which increases the outflow velocity of the dry steam.
    5 to 8 show a further embodiment of the sputtering device according to the invention with a cylindrical housing 180 ', which receives an annular sputtering chamber T. A hollow truncated cone-shaped deflection device 5 'is arranged in the region above the liquid surface. In addition, an annular prism 45 'is arranged in the region of the outlet opening 30, which is formed by the lower end of a hollow-cylindrical outlet tube 70'. The nebulizers 3 'are in a circular arrangement. The operation corresponds to that of dargesteliten in Fig. 1 to 4 embodiment. In the same way, the angular ranges α1, β1, δ1, Φ1 and width ranges a1 given as preferred for the exemplary embodiment according to FIGS. 5 to 8 are also preferred, so that the angles illustrated in FIGS. 5 to 8 are to be considered merely as a possible variant. -10-
