Definitions

  • the invention relates to a high-power radiator, in particular for ultraviolet light, with a discharge space filled with filling gas between two dielectric walls, which walls are provided with first and second electrodes on their surfaces facing away from the discharge space or the electrodes are embedded in the walls with one AC power source connected to the first and second electrodes for feeding the discharge.
  • the invention relates to a state of the art, such as that from G.A.'s publication "Vacuum-ultra-violet lamps with a barrier discharge in inert gases".
  • high-performance lamps in particular high-performance UV lamps, e.g. Disinfection, curing of paints and synthetic resins, flue gas cleaning, destruction and synthesis of special chemical compounds.
  • the wavelength of the emitter will have to be matched very precisely to the intended process.
  • the best-known UV lamp is probably the mercury lamp, which emits UV radiation with wavelengths of 254 nm and 185 nm with high efficiency.
  • a low-pressure glow discharge burns in a noble gas-mercury vapor mixture in these lamps.
  • This radiator consists of a tube made of dielectric material with a rectangular cross section. Two opposite tube walls are provided with flat electrodes in the form of metal foils, which are connected to a pulse generator. The tube is closed at both ends and filled with an inert gas (argon, krypton or xenon). Such filling gases form so-called excimers when an electrical discharge is ignited under certain conditions.
  • An excimer is a molecule that is formed from an excited atom and an atom in the ground state.
  • the UV light generated in a first embodiment reaches the outside through an end window in the dielectric tube.
  • the broad sides of the tube are provided with metal foils which form the electrodes.
  • the tube is provided with recesses, over which special windows are glued, through which the radiation can escape.
  • the efficiency that can be achieved with the known radiator is of the order of 1%, which is far below the theoretical value of around 50% because the filling gas heats up inadmissibly.
  • Another inadequacy of the known radiator can be seen in the fact that its light exit window has only a comparatively small area for reasons of stability.
  • This high-performance radiator can be operated with high electrical power densities and high efficiency. Its geometry is widely adaptable to the process in which it is used. In addition to large, flat spotlights, cylindrical ones that radiate inwards or outwards are also possible.
  • the discharges can be operated at high pressure (0.1 - 10 bar). With this design, electrical power densities of 1 - 50 kW / m 2 can be achieved. Since the electron energy in the discharge can be largely optimized, the efficiency of such emitters is very high, even if one excites resonance lines of suitable atoms.
  • the wavelength of the radiation can be set by the type of fill gas, e.g.
  • mercury 185 nm, 254 nm
  • nitrogen 337-415 nm
  • selenium (196, 204, 206 nm)
  • xenon 119, 130, 147 nm
  • Krypton 124 nm
  • the advantage of these emitters is the areal radiation of large radiation outputs with high efficiency. Almost all of the radiation is concentrated in one or a few wavelength ranges. It is important in all cases that the radiation can escape through one of the electrodes.
  • This problem can be solved with transparent, electrically conductive layers or else by using a fine-mesh wire network or applied conductor tracks as electrodes, which on the one hand ensure the current supply to the dielectric, but on the other hand are largely transparent to the radiation.
  • a transparent electrolyte, for example H 2 O can also be used as an additional electrode, which is particularly advantageous for the irradiation of water / wastewater, since in this way the radiation generated reaches the liquid to be irradiated and this liquid simultaneously serves as a coolant .
  • the invention has for its object to provide a high-power radiator that can be operated with high electrical power densities, has a maximum light exit area and also enables optimal use of the radiation.
  • this object is achieved in that, in the case of a high-power radiator of the generic type, both the dielectrics and the electrodes are transparent to the said radiation.
  • the gas emitted and emitted by a silent discharge fills the gap of up to 1 cm between two dielectric walls (e.g. made of quartz).
  • the UV radiation can leave the discharge gap on both sides, which doubles the available radiation energy and thus also the efficiency.
  • the electrodes can be designed as a relatively wide-meshed grid.
  • the grid wires can be embedded in quartz. However, this should be done in such a way that the UV permeability of the is not significantly impaired.
  • a further variation of the design would be the application of an electrically conductive layers which are permeable to UV instead of the grids.
  • the radiator 1 consists essentially of two quartz or sapphire plates 1, 2, which are separated from one another by spacers 3 made of insulating material, and delimit a discharge space 4 with a typical gap width between 1 and 10 mm.
  • the outer surfaces of the quartz plates 1, 2 are provided with a relatively wide-mesh wire mesh 5, 6, which forms the first and second electrodes of the radiator.
  • the radiator is electrically supplied by an alternating current source 7 connected to these electrodes.
  • AC source 7 can generally be used as they have long been used in connection with ozone generators with the frequencies between 50 Hz and a few kHz (kilohertz).
  • the discharge space 5 is laterally closed in the usual way, was evacuated before closing and was filled with an inert gas or a substance that forms excimers under discharge conditions, e.g. Mercury, noble gas, noble gas-metal vapor mixture, noble gas-halogen mixture, filled, possibly using an additional noble gas (Ar, He, Ne) as a buffer gas.
  • an inert gas or a substance that forms excimers under discharge conditions e.g. Mercury, noble gas, noble gas-metal vapor mixture, noble gas-halogen mixture, filled, possibly using an additional noble gas (Ar, He, Ne) as a buffer gas.
  • the electron energy distribution can be optimally adjusted by varying the gap width (up to 10 mm) of the discharge space, pressure (up to 10 bar) and / or temperature.
  • plate materials also come, e.g. Magnesium fluoride and calcium fluoride in question.
  • the plate material is glass for spotlights that are supposed to deliver radiation in the visible range of light.
  • a wire mesh there can also be a transparent, electrically conductive layer, the layer made of indium or tin oxide for visible light, a 5 - 10 nm (50 - 100 angstroms) thick gold layer for visible and UV light, and especially one in UV thin layer of alkali metals can be used.
  • a first quartz tube and a second quartz tube 9 distanced therefrom are arranged coaxially one inside the other and are spaced apart by means of annular spacer elements 10 made of insulating material.
  • the annular gap 11 between the tubes 8 and 9 forms the discharge space.
  • the first electrode is a thin UV-permeable electrically conductive layer 12, e.g. made of indium or tin oxide or alkali metal or gold, provided on the outer wall of the outer quartz tube 8 and a layer 13 of the same type as a second electrode on the inner wall of the inner glass tube 9.
  • the discharge space is filled with a substance or mixture of substances according to the table above.
  • the emitters described are well suited as high-yield photochemical reactors.
  • the reacting medium is guided past the front surface and the rear surface of the radiator.
  • the medium is passed through both inside and outside.
  • the flat radiators can be hung, for example, as "UV panels” in the chimney of chemical cleaners and other industrial companies to destroy residues of solvents (e.g. chlorinated hydrocarbons).
  • solvents e.g. chlorinated hydrocarbons
  • omnidirectional radiators can be combined into larger batteries and used for similar purposes.
  • Improvements can also be achieved in the mirroring of the UV emitters emitting on one side according to the patent application mentioned at the beginning.
  • the above-mentioned three times through the absorbent quartz walls can be avoided by attaching the UV reflective coating (e.g. aluminum) on the inside and then covering it with a thin layer of magnesium fluoride (MgF 2 ). In this way, the radiation would only have to pass one quartz wall at a time.
  • the UV reflective coating e.g. aluminum
  • MgF 2 magnesium fluoride
