Description

  • The invention relates to a device for the treatment of liquids with at least one directed to the liquid UV light-emitting element. Furthermore, the invention relates to a method for the treatment of liquids, wherein the liquid is irradiated by means of at least one UV light-emitting element with UV radiation.
  • From the DE 101 38 384 A1 is a device for disinfecting and sterilization of mixed water in a water storage known in which a reaction mixer is provided with a UV unit.
  • In the DE 20 2011 051 637 U1 An arrangement for the treatment of liquids is described in which a UV treatment device and an ion treatment device are arranged in series in a liquid flow to be treated in series.
  • In these known devices, therefore, UV radiation is used to kill germs present in the liquid. The known devices are used for example for the treatment of drinking water, aquarium water, pond water or other water, in which it depends on a high degree of purity.
  • The problem with the known devices, however, is the fact that the UV elements used in this case at all times with the same radiation act on the liquid, resulting in some cases too strong, but often too weak treatment.
  • It is therefore an object of the present invention to provide an apparatus and a method for the treatment of liquids, with which a more effective treatment of the liquid is possible.
  • According to the invention, this object is achieved by the features mentioned in claim 1.
  • By means of the measuring device according to the invention, it is possible to measure the flow rate and / or the contamination of the liquid and to control the performance of the UV light-emitting element in dependence thereon. For this purpose, the UV light-emitting element is coupled via a control device with the measuring device, so that the UV light-emitting element operated at any time with the desired performance and thus the liquid can always be treated in the necessary manner. For example, the power of the at least one UV light-emitting element is increased when a larger flow rate of the liquid is detected by means of the measuring device, since in this case a larger amount of liquid to be cleaned is present. Even with a greater contamination of the liquid, the performance of the at least one UV light-emitting element is increased in order to take account of the greater pollution and to obtain optimum cleaning performance. Conversely, it behaves when a smaller flow rate or less contamination of the liquid is detected. In these cases, we reduce the performance of the at least one UV light-emitting element, whereby an energy saving is achieved.
  • This variability of the device according to the invention always achieves the optimum degree of cleaning in conjunction with the most efficient use of electrical energy.
  • In a very advantageous embodiment of the invention can be provided that the measuring device has a luminous element and a measuring element for measuring the transmission of light through the liquid. This represents an equally simple and reliable embodiment of the measuring device.
  • A simple eizusetzende in practice development of the invention may consist in that the measuring element is designed as a photodiode.
  • In order to achieve a saving of components, it can further be provided that the luminous element of the measuring device is the at least one UV luminous element.
  • Alternatively, it can also be provided that the luminous element of the measuring device is an additional luminous element arranged upstream of the at least one UV luminous element. Such an embodiment is particularly preferable when reacting very quickly to changing flow rates and / or contamination of the liquid.
  • An improved effectiveness of the at least one UV light-emitting element results when the at least one UV light-emitting element is arranged in a hollow body through which the liquid flows.
  • In this context, it can also be provided that the at least one UV light-emitting element is arranged so that it has direct contact with the liquid. Eliminating a separate glass tube or the like avoids degradation in efficiency that might otherwise occur if, for example, the glass tube becomes cloudy due to deposits.
  • In a further very advantageous embodiment of the invention, it can be provided that a plurality of UV light-emitting elements, which are connected to the control device by means of a bus system, are provided on the liquid. By using a plurality of UV light elements, which may for example be arranged in strips one behind the other, a longer contact of the liquid with the UV radiation is ensured, resulting in a more efficient cleaning process of the liquid.
  • In order to be able to vary the power of the at least one UV light-emitting element as a function of other factors, it may further be provided that at least eleven further measuring element is connected to the control device for measuring at least one property of the liquid.
  • A procedural solution of the problem is specified in claim 10.
  • By means of said method results in a very efficient cleaning process for a wide variety of liquids, with an optimal degree of purification and energy-efficient use of at least one UV light-emitting element are always guaranteed.
  • Hereinafter, an embodiment of the invention with reference to the drawing is shown in principle.
  • It shows:
  • 1 a very schematic representation of a device according to the invention for the treatment of liquids.
  • 1 shows a device 1 for the treatment of liquids, such as drinking water, aquarium water, pond water or the like. As a result, the device could 1 for example, be installed in a drinking water line, an aquarium a pond or the like. Particularly preferred is the installation of the device 1 in filter systems and / or on or in their supply and / or discharge devices.
  • The device 1 has at least one UV luminous element 2 on. In the present case are several, namely three UV light elements 2 provided, which are arranged one behind the other in the flow direction of the liquid designated by "x". Through the UV light elements 2 the liquid is irradiated with UV radiation and thereby cleaned. The precise effect that UV radiation has on the liquid and the bacteria and other impurities contained in the liquid is known per se and will therefore not be described further here. The wavelength of the UV light elements 2 emitted radiation is less than 390 nm. The exact wavelength can be selected depending on the type of contamination of the liquid. In this context, it is also possible that in the present case, three UV light elements 2 Emit radiation at different wavelengths.
  • For the UV light elements 2 are preferably LEDs. The UV light elements 2 are in a hollow body through which the liquid flows 3 , For example, a pipe or hose arranged. Here are the UV light elements 2 so executed or arranged so that they are in direct contact with the liquid. In other words, it is applied to glass tubes or other cladding in which the UV light elements 2 could be arranged waived. The UV light elements 2 can be arranged on a common component and, for example by means of a variable quick connection to the hollow body 3 be attached.
  • In order to measure a flow rate and / or contamination of the liquid, the device has 1 Furthermore, a measuring device 4 on, via a control device 5 with the UV light elements 2 is coupled. In this way, the electrical power of the UV light elements 2 to be controlled. The UV light elements 2 For example, by means of a bus system with the control device 5 be connected. In the present case, such UV light elements 2 used, whose performance can be changed or have a variable performance. The control device 5 It is designed in such a way that it is that of the measuring device 4 measured values with respect to the flow rate and / or contamination of the liquid processed and the UV light elements 2 or in general the at least one UV light-emitting element 2 so that the power of the same is adapted to the respective flow rate or the respective contamination of the liquid. The performance of the UV light elements 2 So is by means of the control device 5 controlled as a function of the flow rate and / or the contamination of the liquid.
  • The measuring device 4 has a light-emitting element in the illustrated embodiment 6 and a measuring element 7 for measuring the transmission of the light from the element 6 emitted light through the liquid. The light element 6 and the measuring element 7 are also with the controller 5 connected. In the illustrated embodiment, the measuring element 7 formed as a photodiode, which is offset by 180 ° to or directly opposite of the luminous element 6 inside the hollow body 3 is arranged. In the luminous element 6 it is an additional one Luminous element, the upstream of the UV light elements 2 is arranged. As a result, the liquid first flows to the additional, to the measuring device 4 belonging lighting element 6 over, so that, a correspondingly short response of the control device 5 assuming the performance of the UV light elements 2 can be controlled so that, until the respective pollution in the range of UV lighting elements 2 arrives, their performance is already adjusted.
  • As an alternative to this embodiment as an additional luminous element 6 It would also be possible to use one of the UV light elements 2 as the luminous element 6 the measuring device 4 use. In principle, this would also be possible if only one UV light element 2 is provided.
  • Furthermore, the device 1 in the illustrated embodiment, two further measuring elements 8th and 9 for measuring at least one property of the liquid. The stated property of the liquid may be, for example, the degree of hardness of the liquid or the pH of the liquid. For example, depending on the degree of hardness of the liquid, a certain influence on the measured values can be made. Further properties or values of the liquid which can be measured with optionally further measuring elements are, for example, salinity, carbonate hardness, total hardness, temperature, content of nitrite, nitrate, ammonia, carbon dioxide, oxygen, phosphate, trace elements, calcium, magnesium, bicarbonate, aluminum, Ammonium, antimony, arsenic, lead, boron, cadmium, chloride, chromium, cyanide, iron, fluoride, potassium, copper, manganese, sodium, mercury, selenium, silicate, strontium, sulfate, uranium, zinc, organic chlorine compounds, pesticides and biocidal products , as well as conductivity, germ density of different germs, and redox potential.
