Definitions

  • the invention relates to an electrostatic filter with an ionization unit and a separation unit for cleaning a gas flow.
  • the electrode plate has a front edge and a rear edge, viewed in the direction of flow, which are positioned in front of the ionization element, viewed in the direction of flow.
  • the rear edge of the electrode plate is also arranged in front of the ionization element. The rear edge is located in the inflow direction in front of a plane in which the ionization element is located and which extends perpendicularly to the inflow direction.
  • a voltage can be applied between the ionization element and the electrode plate, so that an electric field is created.
  • the particles transported in the gas flow are ionized by the electric field.
  • Ionization means that the particles are electrically charged, so that each particle has an excess of electrons, for example.
  • the gas flow can be an air flow. In addition, it can also be other gaseous media or mixtures.
  • the gas flow contains particles that are transported along with it. Particles can be dirt or dust particles that arise in industrial processes such as metal-cutting shaping (e.g. turning and milling using coolants). The particles can also be fine dust or the finest particles, right down to microscopically small suspended matter or particles. A particle can also be a liquid substance. Accordingly, particles can also be droplets or aerosols. Droplets or aerosols can also be carriers of viruses or bacteria, so that the filter according to the invention can be used to filter viruses or bacteria. Ozone, which can form in the ionization unit, can advantageously be used to kill viruses or bacteria.
  • the filter can be used in extractors, air conditioners, room fans or ventilation systems.
  • An advantageous arrangement of ionization element and counter-electrode is realized by the invention.
  • the position of the electrode plate with its rear edge makes it possible for the ionization and the associated flow of electrons between the ionization element and counter-electrode to take place in front of the ionization element, viewed in the flow direction.
  • the sharp contour of the rear edge promotes the desired ionization.
  • an advantageous flow behavior of the gas flow can be adjusted by the electrode plate connected upstream of the ionization element.
  • the counter-electrode can be positioned in such a way that the particles are exposed to the ionization for a long time and thus an efficient ionization takes place.
  • the direction of the gas flow and the particles is preferably aligned and/or calmed by the electrode plate.
  • a turbulent gas flow can be converted into a directed gas flow by flowing around the electrode plate.
  • the gas flow and the particles preferably do not experience any turbulence.
  • the configuration can also prevent stagnation points.
  • Stagnation points are points at which flow-related particles are deposited because there is no air movement in the stagnation point.
  • a further advantage is the simple design of the counter-electrode on the basis of plates or metal sheets, as a result of which the filter can be manufactured at low cost.
  • the rear edge of the electrode plate runs parallel to the longitudinal axis of the ionization element.
  • a constant distance from the rear edge of the electrode plate can thus be set over the entire length of the ionization element. This enables continuous and efficient ionization to be achieved over the entire length of the ionization element.
  • the precipitation plates also have the additional function of specifying the direction of gas flow and particles through the plate.
  • the electrode plate and the precipitation plate can advantageously be matched to one another, for example by lying in one plane and thus providing a good flow profile.
  • the ozone that has formed on the ionization element can be transported away or broken down by the precipitation plates. Due to the design as a flat sheet, the precipitation plate is particularly easy to clean. It is also conceivable for the ozone and/or for particles which could not or could not be separated from the gas flow in the separation unit could be dismantled to provide a downstream after-treatment. This can include the use of an activated carbon filter. Filter media made of glass fibers can also be used here.
  • the precipitation plate can have a front edge which is arranged behind the ionization element as seen in the direction of flow and whose distance from the ionization element preferably corresponds to the distance from the rear edge of the electrode plate of the counter-electrode to the ionization element.
  • the rear edge of the electrode plate of the counter-electrode and the front edge of the collecting electrode lie on the circumference of a circle whose center coincides with the longitudinal axis of the ionization element and whose radius corresponds to the distance.
  • the precipitation plate is therefore not only used to separate the particles from the gas flow, but can also contribute to the ionization of the particles.
  • the counter-electrode has at least two additional electrode plates, the ratio of one The distance between the two additional electrode plates and the distance between the ionization element and the rear edge of the electrode plate is 1.5 to 2.5, preferably 1.8 to 2.2. If the counter-electrode has more than two additional electrode plates, the distance described here is the distance between two adjacent additional electrode plates. It has been found that with the above ratio, a compact ionization unit with good efficiency can be implemented.
  • the separating unit 3 has three precipitation plates 9 and two intermediate plates 10 which are arranged between two adjacent precipitation plates.
  • the precipitation plates 9 and the intermediate plates 10 are in the figure 1 shown only partially and therefore in a shortened form.
  • the rear edges 14 of the electrode plates 7 can also lie in a common plane which is aligned parallel to the plane E. In this case, the individual rear edges 14 would not be at the same distance from the ionization element 4.
  • the electrode plates 7 and the additional electrode plates 8 are grounded, while a voltage is applied to the ionization element.
  • the precipitation plates are also grounded, with the intermediate plates also being subjected to a voltage.
