Definitions

  • the invention relates to a device for generating defined, ionized gases or ionization products and their lossless transport.
  • Air ions Research into the biological activities of charged particles in air ions indicates a certain potential of their general biological, physiological and therapeutic effects. So far it has been assumed that the biological action of the air ions is achieved by regulating the membrane charge of the erythrocytes and acting on the central regulatory systems down to the brain and the glands of internal secretion.
  • the use of air ions is known, for example, for diseases such as bronchial asthma, bronchitis, pneumonia, hypertension, etc.
  • FR-A-2 202 625 describes a method with which gaseous ions can be generated by a corona discharge.
  • the large diameter of the supply tube creates a large volume flow. The consequence of this is that only relatively low oxygen anion radical generation can take place.
  • a relatively high voltage is required, which contains a comparatively large amount of harmful by-products, e.g. Generates ozone. In this process, nitrogen must therefore first be ionized, with which the oxygen is then subsequently ionized.
  • a device for producing ionized gases which has a tubular outer electrode and an inner electrode.
  • the inner electrode is heated with alternating current and there is a potential difference between it and the outer electrode.
  • EP-A-0 029 421 a device is known from EP-A-0 029 421, in which a potential difference is generated between the inner electrode and electrodes within the outer electrode.
  • the object of the invention is therefore to create a device for generating defined, ionized gases or ionization products, in particular oxygen anion radicals, in which the production of harmful by-products is minimized at the same time, and to transport them almost without loss.
  • the resulting defined ionized gases or gaseous products have a previously unknown physiological effectiveness. This is attributed in particular to the relatively high concentration of oxygen anion radicals generated. No or only small amounts of by-products, e.g. Ozone.
  • FIG. 1 shows a device according to the invention for generating defined, ionized gases or ionization products, in which a gas stream 1 to be ionized enters a tubular, cylindrical hollow electrode 3.
  • a high voltage supplied by a voltage source 2 is applied to the one-piece hollow electrode 3.
  • This high voltage energizes the gas molecules flowing through before they reach the area of the inner electrode 4. Due to the previous excitation, the corona voltage can be reduced to 2.5 to 4 kV, whereby the formation of by-products, e.g. Ozone, values that are essentially not higher than those found in nature.
  • the actual corona discharge takes place at the inner electrode 4.
  • the outer electrode 3 and the inner electrode 4 are on the same or the inner electrode is at a lower, negative electrical potential. At least a portion of the inner electrode 4 is close to the gas outlet opening 9 of the outer electrode 3.
  • the inner electrode 4 is formed in one piece and consists of a wire-shaped area 5 and a needle-shaped area 6, which lies close to the gas outlet opening 9, in order to keep the concentration loss of ionized gas molecules as small as possible.
  • the size and shape of the inner electrode 4 is selected in relation to the inner region of the tubular outer electrode 3 so that it can ionize a large proportion of the gas molecules flowing through, so that defined ionization products are formed.
  • the concentration and the qualitative composition can also be controlled via the flow velocity of the gas molecules. The lower the flow rate in the specified range, the higher the concentration of the ionized products, e.g. Oxygen anion radicals If the potential difference between the outer electrode 3 and the inner electrode 4 is negative, the inner electrode 4 is held by supports 7 made of insulating material. To protect against electric shock, the outer electrode is covered with an insulating touch protection 8.
  • FIGS. 2 and 3 describe a device for generating defined, ionized gases or ionization products, which consists of a tubular, cylindrical hollow electrode 3 and two internal electrodes each.
  • One inner electrode 10 is arranged in each case in the gas inlet area, the other inner electrode 11, 12 is arranged in the gas outlet area.
  • the input inner electrode 10 serves for additional pre-excitation of the gas molecules.
  • the generation of defined ionization products can be achieved in a wide flow rate range of the gases, the formation of by-products still not exceeding the values occurring in nature.
  • Due to the conical shape of the outer electrode 3 in FIG. 3, a different flow rate at the inner input electrode 10 and the output electrode 12 is achieved.
  • the relationships of the input and output surfaces of the hollow electrode 3 according to FIG. 3 are in a range up to max. 10: 1.
  • a ratio of 2: 1 and 3: 1 has proven to be particularly advantageous.
  • the internal electrodes 4 are designed either as a metal tip or as a wire mesh.
  • a wire mesh instead of a wire mesh, of course, any equivalent embodiment can be selected.
  • FIGS. 4 and 4a A further embodiment of the inner electrode as a wire mesh can be seen from FIGS. 4 and 4a.
  • the wire mesh is formed in that individual wires are angularly offset in several parallel planes.
  • the number of wires used is variable.
  • four wires 13 a, b, c, d
  • Figure 4a shows a top view of the resulting shape of the wire mesh.
  • the diameter of the wire that forms the wire mesh is preferably in the range between 0.05 and 0.3 mm.
  • the individual wires which each form an electrode system, are advantageously arranged perpendicular to the gas stream 1.
  • FIG. 5 describes a further embodiment of the inner electrode 4.
  • the inner electrode consists of a base 14 and a cylindrical electrode body, which can have, for example, a round or pointed end.
  • the base 14 is connected to the outer electrode 3 on the gas inlet side and has openings 16 through which the gas flow into the outer electrode 3 entry.
  • FIG. 6 designates a device for ionizing gases, in which the outer electrode 3 is not formed in one piece, but is divided into several electrode areas.
  • an outer electrode with three electrode regions 17, 18, 19 is used.
  • the gas 1 to be ionized enters the outer electrode area 18 at the entrance area. This is connected to a voltage source U1.
  • the gas molecules excited in this way pass through a first grid-shaped or perforated inner electrode 21 and arrive in a second selection electrode area 19.
  • a voltage U 2 different from U 1 is applied to this area.
  • the gas mixture flows through a third outer electrode region 20.
  • a second inner electrode 22 mounted on the output side is arranged in this region.
  • the area 20 is supplied with a voltage U3.
  • All outer electrode regions 18, 19, 20 are separated from one another by insulation bodies 23.
  • insulation bodies 23 For example, Teflon (trademark) is used as insulation material.
  • the pre-excitation of the gas can be improved even further, for example by a higher negative potential with U1> U2> U3 or U2> U3.
  • metal in particular platinum, gold or copper
  • platinum is preferably used as the electrode material.
  • cobalt-salt-coated or cobalt-alloyed electrodes ie needles, grids, chips and inner surfaces. Cobalt salts decompose ozone to oxygen.
  • oxygen is preferably used as the gas.
  • an oxygen or air volume flow of less than 5 ml / min, preferably of 1-3 ml / min is sufficient if a hollow electrode with a cross-sectional surface of 1 mm2 is used.
  • the device for ionizing gases according to the invention can also be used for sterilization.
  • the outer electrode 3 On the side opposite the entry area, the outer electrode 3 is closed off by a wall 25.
  • the outer electrode 3 is connected to a voltage source 3, which supplies a high voltage of 5 to 12 kV.
  • a fibrous inner electrode 26 is attached at one end to a support 7 and at the other end to the wall 25. Carbon is preferably selected as the material of the inner electrode 26, so that only low ozone formation and metal emissions can arise at the high voltage used.
  • a plurality of holes 27 are arranged in the longitudinal area of the hollow electrode 3.
  • the incoming gas is ionized on the inner electrode 26.
  • the finished ionization product exits through holes 27.
  • the ratio of the diameter of the electrode to each hole is preferably between 1: 1.5 and 1: 4. Instead of a row of holes, an outlet slot or an outlet opening equivalent thereto can also be provided.
  • the device is used, for example, for the sterilization of food and possibly packaging containers.
  • Another preferred area of application is the sterilization and sterile maintenance of medical and dental instruments, medical workplaces and hollow bodies, which e.g. be used in medicine.
