Definitions
- the invention relates to the field of disinfection.
- the invention relates to a device and a method for the combined disinfection of surfaces and indoor air in the healthcare sector.
- room air disinfection with ozone In addition to simple wipe disinfection and room air disinfection with hydrogen, room air disinfection with ozone has also been known for a long time. Room air mixed with ozone interacts with contaminated surfaces and, after a corresponding waiting period, also reaches regions that are otherwise difficult or impossible to access. At the same time, the room air itself is also disinfected. After disinfection with ozone, the room air can be actively freed of ozone by decomposing the ozone, e.g. by irradiating it with UV light of e.g. 254 nm. Fast and combined disinfection of room air and surfaces is achieved using devices that use UV radiation. The disinfecting effect of such radiation is known, for example, from the publication EP 2391421 A1.
- Document DE 10 2015 102882 A1 discloses a device which combines the advantages of both technologies. Accordingly, this Document a disinfection device for the combined disinfection of room air and surfaces, comprising both a device emitting into the environment for generating UV-C radiation and a device for generating ozone, wherein the disinfection device also comprises a control which is coupled to the device for generating UV-C radiation and the device for generating ozone, and with which the timing of the operation of these devices can be controlled separately.
- the invention is based on the object of providing a device and a method which avoids the disadvantages of the prior art.
- the invention is intended to improve a device of the aforementioned type in such a way that the disinfection time is reduced and/or the efficiency is improved.
- the object is achieved by a disinfection device according to claim 1 and a method according to the independent claim 11.
- Advantageous embodiments can be found in the respective dependent subclaims, the following description and the figures.
- a disinfection device for the combined disinfection of room air and surfaces that solves the problem underlying the invention comprises both a device that emits UV-C radiation into the environment and a device that can be controlled separately from this to generate ozone.
- the device for generating ozone partially converts the oxygen present in the room air into ozone.
- the gaseous ozone can also penetrate into inaccessible places such as the smallest cracks, and remains It stays there for a certain time because it does not decompose immediately and leads to the destruction of microorganisms. In this way, both surfaces that come into contact with the gas and the room air are disinfected. Odor molecules are also destroyed, which subjectively leads to fresher room air.
- the device emitting UV-C radiation into the environment produces light with a wavelength in the range of 100 nm to 280 nm. On any surface irradiated with this light, the DNA of microorganisms is changed so that their reproduction is prevented. This results in the germs being deactivated within seconds.
- Another effect of UV lamps, which are typically low-pressure lamps, is the destruction of ozone, i.e. residual ozone is converted back into atmospheric oxygen.
- the device for generating ozone and also the device for generating UV-C radiation can have a single, but typically a plurality or a multitude of radiation-emitting components. These can also be combined in groups so that they can be controlled as a single unit.
- Both the device for generating ozone and the device for generating UV-C radiation typically have a "length". This means that they (i.e. their light sources) are not merely point-shaped or individually spherical, but are either designed in the shape of a rod or column, for example, or comprise a plurality of individual sources, which in turn can be combined to form a corresponding rod or column shape, for example.
- the two devices also have an "emission surface” which faces the environment, and a “rear surface” which does not face directly into the environment, but typically faces in the direction of the disinfection device.
- the "rear surfaces” are “facing" the disinfection device, the
- the disinfection device also comprises a control system which is coupled to the device for generating UV-C radiation and the device for generating ozone, and with which the timing of the operation of these devices can be controlled separately.
- a control therefore serves to control the temporal sequence of the operation of the individual devices separately from one another.
- the control allows the device for generating ozone to be operated first, and then the device for generating UV-C radiation to be operated.
- the disinfection device is designed to convey room air along the device for generating UV-C radiation and/or the device for generating ozone. This means that fresh air is set in motion - preferably continuously - in such a way that the air in the immediate vicinity of the components of the two aforementioned devices that emit UV-C radiation is constantly exchanged.
- At least one outlet leading into the environment is present both along the device for generating UV-C radiation and along the device for generating ozone, through which the room air can be conveyed in the direction of the device for generating UV-C radiation and/or the device for generating ozone.
- This outlet is preferably aligned in such a way that it points in the direction of the radiation-emitting components, thereby achieving the best possible air exchange at the relevant locations.
- "in the direction” means in any case the immediate vicinity of the radiation-emitting components, which also leads to the desired result.
- the outlet(s) can also be optionally closed during operation. This can be advantageous if only one of the two aforementioned types of radiation-emitting components (UV-C or ozone-generating unit) is in operation, so that only this one needs to be supplied with fresh air. In this way, the effectiveness is further improved.
- the ozone-enriched air moved by the ozone generation device distributes the ozone more effectively in the room, which increases process reliability and shortens treatment time.
- the air moving past the ozone generation device increases the oxygen content at that device, making ozone production more efficient.
- the invention thus avoids the disadvantages known from the prior art.
- ozone can be actively released and distributed into the room, the efficiency can be improved by cooling, and the efficiency of ozone production can be increased by increasing the oxygen content.
- the outlet(s) are in the form of round openings.
- the size of the openings and their distance from one another must be selected in such a way that the air flow to the respective device is actually sufficient for the purposes mentioned above.
- the outlet(s) are in the form of slot-shaped openings. These can preferably run along the longitudinal extension of the radiation-emitting components of the two devices. In extreme cases, a single slot-shaped opening is sufficient. This can have a variable width, for example for passive control of the volume flow leaving the opening at a certain point (a wider slot allows a larger volume flow). This also enables adaptation to variable pressure conditions along the opening, for example due to increasing distance from a fan. In the same way, the distances or Cross-sections of round (or other shaped) openings can be adjusted to achieve, for example, a uniform air flow through the equipment.
- At least 20%, 30%, 40%, 50%, 60% or 70% of the length of the device for generating UV-C radiation and/or the length of the device for generating ozone can be flowed through with room air from the outlet(s).
- an outlet can flow over a somewhat larger area than its cross-section; nevertheless, it is clear that a sufficient cross-sectional size and a sufficient air flow must be present in order to achieve the said percentage values.
- the total volume flow of room air conveyed through the outlet(s), averaged along the length of the devices is between approximately 10 and 1000 m 2 /h, preferably between 30 and 700 m 2 /h, and particularly preferably between 100 and 500 m 2 /h.
- the numerical values mentioned can also be combined with one another in ways other than those stated above. With such a volume flow, sufficient cooling of the radiation-emitting components of the devices can be achieved, combined with an increase in efficiency and good transport of the treated room air into the room.
- the device for generating UV-C radiation and/or the device for generating ozone comprises UV-C lamps, the sides of which facing the disinfection device are arranged opposite the outlets.
- “Facing” here means “towards a center of the device”.
- “Facing away” would therefore mean “into the room”.
- both the device for generating UV-C radiation and the device for generating ozone comprises a plurality of UV-C light-emitting, vertically aligned and radially emitting radiators, which are arranged alternately and/or opposite one another along a circumference of the device.
- a largely even distribution of the radiators is ensured, which leads to an advantageously even generation/distribution of disinfecting UV radiation and provision of ozone-containing room air.
- this embodiment requires very little floor space.
- linear radiators can also be in the form of a longitudinal spiral or longitudinal screw.
- a longitudinal spiral winds around a center like a screw. Tests have shown that such a shape can achieve particularly good illumination of the room.
- Such a longitudinal spiral also has a "length" according to the above definition, namely once along the actual spiral, as well as along the cylinder around which the spiral runs.
- the radiators can also be designed in a ring shape and run around a column, for example. In particular, several rings spaced apart from one another are possible.
- the spotlights can be in the form of a large number of point-shaped light sources, particularly in the form of LEDs. These also have an "emission surface” and a “rear surface”. The rear surfaces must then be flowed over or around in the manner described above in order to achieve the desired effect. Accordingly, by definition, room air is conveyed "in the direction" of such light sources even if their flow is not directed directly at them, but rather exchanges the air in their immediate vicinity.
- the outlets are arranged in a central column into which the room air can be conveyed.
- the room air is sucked in from below by means of a fan, for example, and pressed into the column. From there it exits again through the outlets.
- the radiators e.g. linear or screw-shaped, are arranged around the column. It is clear that the outlets should be arranged according to the position of the radiators in order to keep the flow paths short and minimize flow losses.
- the disinfection device is mounted so that it can rotate and is driven by a motor. In other words, the device can rotate around a preferably vertical axis using a drive.
- the illumination of the room and the surfaces to be disinfected is more even, since the necessarily discrete distribution of the radiator(s) along the circumference of the device means that certain areas can be illuminated better and those in between less well.
- the rotation blurs the edges of the shadow areas, so that a larger surface is exposed to the radiation overall.
- the rotary mounting can be achieved, for example, in that the device comprises a base frame and an upper frame rotatably connected to the base frame, on which at least the device for generating UV-C radiation and preferably also the device for generating ozone are arranged.
- a rotary mounting can be advantageous if, for reasons of cost or space, only a few lamps are available, which do not allow uniform illumination without mobility. If the treatment time is of secondary importance, a device with a reduced number of lamps can achieve practically the same disinfection effect as a device with a larger number of lamps.
- the component which comprises the outlets (for example the column) is also rotatable, so that the flow paths from the outlet to the radiator always remain as short as possible, even when the radiators rotate.
- the disinfection device is mounted on a rolling base. This makes it particularly easy and safe to transport from one room to another.
- the rollers can also be drivable.
- the drivable rollers can also be used to enable better illumination of, for example, an elongated room, similar to the rotation mentioned above, by rotating the device about an axis or moving along a predetermined path.
- the disinfection device preferably comprises a filter through which the room air can be sucked in.
- the filter is, for example, an activated carbon filter or preferably an ozone catalyst, which can be present, for example, as a flow-through block or flow-through granulate. This has the function of reducing the ozone content in the room more quickly in a (second) operating phase "ozone reduction".
- the flow of air through the radiators according to the invention can be controlled independently of the flow through the filter. Otherwise, the ozone that is desired in a (first) operating phase "ozone generation" would be immediately eliminated again.
- either two independent fans flow fans for the radiators and flow through fans for the filter
- switchable flow channels are available so that the room air can be used optionally for flowing air through the radiators and/or for flowing through the filter.
- the disinfection device comprises a device for contactless recognition of a room and a device for logging the operation.
- the device for contactless recognition for example based on RFID, serves to automatically identify in which room the disinfection device is to be used.
- a program suitable for this room is stored in a memory, which is sent to a controller and processed by it.
- the device for logging stores the time and type of program so that the use of the disinfection device can be traced.
- the invention also relates to a method for operating a disinfection device as described above. It is characterized in that during operation of the device for generating UV-C radiation and/or the device for generating ozone, room air is conveyed along this device(s), and more precisely, along its radiation-emitting components (emitters).
- room air is conveyed along this device(s), and more precisely, along its radiation-emitting components (emitters).
- the room air is directed through outlets towards the device for generating UV-C radiation and/or the device for generating Ozone is promoted.
- the device for generating UV-C radiation and/or the device for generating Ozone is promoted.
- the conveying takes place by means of a flow fan, which sucks in the room air and blows it into a column, in the wall of which the outlets are arranged.
- the outlets should be arranged as close to the radiators as possible in order to keep the flow losses as low as possible.
- the use of a single, central (flow) fan is more advantageous than the use of a large number of separate fans.
- individual fans or the like installed in the outlets, which ensure the movement of the air according to the invention.
- these devices rotate at least temporarily while being exposed to ambient air.
- the rotation makes the room more evenly illuminated; the exposure of the lamps to ambient air improves efficiency and shortens the treatment time.
- the room in which the disinfection is to take place is detected without contact.
- a program suitable for disinfecting the room is then called up from a memory and sent to a control system. This controls the operation of the device for generating UV-C radiation, the device for generating ozone, as well as the supply of room air, and records the operation.
- the device for generating ozone is initially in operation for a first time interval, followed by operation of the device for generating UV-C radiation for a second time interval.
- the flow of air through the radiators according to the invention takes place; only during the second time interval does the flow through the filter take place (at least also).
- the correspondingly active radiators, or all of the radiators continue to be flowed through in the second interval as well.
- Figure 1 is a view of an embodiment of the disinfection device according to the invention.
- Figure 2 shows a section of the column of another embodiment of the disinfection device
- Figure 3 is a schematic flow diagram of the inventive
- Figure 1 shows a view of an embodiment of the disinfection device 1 according to the invention.
- This comprises a device for generating UV-C radiation 2 and a device for generating ozone 3. More precisely, the device for generating UV-C radiation 2 shown comprises vertically aligned and radially emitting UV-C emitters, for example with a wavelength of 254 nm, and the device for generating ozone 3 comprises similarly arranged and oriented UV-C emitters, for example with a wavelength of 187 nm.
- the two types of emitters are arranged alternately. Accordingly, the emitters of the two devices 2 and 3 are arranged alternately and adjacent to one another along the circumference of the disinfection device 1 and are evenly distributed around the circumference.
- the device 1 comprises a base frame 4 equipped with rollers and an upper frame 5 mounted thereon.
- the control 6 arranged in the base frame 4 is only indicated.
- Also shown are preferably existing presence sensors 7 (only one provided with a reference number) with which the presence of persons, and/or the ozone content of the room air, and/or its germ load can be measured.
- the column 8 of the upper frame 5 there are a number of slot-like, vertical outlets 9 (only one is provided with a reference number), through which the room air can be conveyed in the direction of the device for generating UV-C radiation 2 and the device for generating ozone 3.
- the sides of the radiators facing the disinfection device 1 are arranged opposite the outlets 9 in order to keep the flow paths as short as possible.
- the column 8 is hollow and is supplied with room air from below by a fan 10 (shown only in outline), which then exits through the outlets 9.
- a part of the device for contactless detection of a room 13 is arranged on top of the column 8 in the form of an antenna.
- a handle 14 is arranged around the column 8, which also serves as protection for the radiators.
- the disinfection device 1 further comprises a filter 11 (only shown in outline) with a downstream flow fan 12 (only shown in outline), through which room air can also be sucked in.
- the room air sucked in through the filter 11 is also conveyed into the column 8, from where it can flow out through the outlets 9.
- the filter 11 serves to reduce the ozone content of the room air more quickly in the second operating phase, in which the UV surface disinfection takes place.
- the associated flow fan 12 should only be in operation in this operating phase, if necessary.
- Figure 2 shows a section of the column of another embodiment of the disinfection device.
- the column 8 is shown here as cylindrical, but can also have a different cross-section.
- LEDs emitting UV light of corresponding wavelengths are arranged directly on the column 8 as a device for generating UV-C radiation 2 and a device for generating ozone 3.
- the disinfection device is designed to convey room air "along" the two devices 2, 3.
- the area immediately in front of the radiation-emitting units is also included in these.
- the room air is thus also further conveyed "in the direction" of the devices 2, 3, since the outlets 9 are positioned directly at their radiation-emitting units (the LEDs) and flow into the area to the side and in front of the LEDs.
- the advantageous cooling according to the invention is achieved, but above all the increase in efficiency through the transport of room air from the column 8 into the area immediately in front of the radiation-emitting units, in which the reactions with the room air actually take place.
- the room air located immediately in front of the units is constantly exchanged.
- the outlets 9 also ensure efficient transport and distribution of the treated room air into the environment.
- Figure 3 shows a schematic flow diagram of the method according to the invention. After the start of operation, the room is first recognized using REID or another method and the program suitable for treating it is called up from a memory.
- the first operating phase in which ozone is generated by means of the ozone generation device 3 .
- This is actively released into the room by the operation of the air flow fan 10 .
- the efficiency of the corresponding radiators is improved due to their cooling .
- the active distribution of the ozone-containing room air shortens the operating time and improves process reliability .
- the increased oxygen content in the radiators also increases the efficiency of ozone production .
- the device for generating ozone 3 is switched off and the device for generating UV-C radiation 2 is switched on.
- the airflow fan 10 can, but does not have to, be switched off.
- the airflow fan 12 is switched on so that the ozone is filtered out of the room air and the concentration is quickly reduced.
- an advantage is achieved because the operating time is reduced due to the active ozone reduction.
