Definitions

  • the invention relates to a method for cleaning contaminated fluids, i. H. of gases or liquids, by means of liquid washing; it also relates to a device for cleaning contaminated fluids according to the preamble of claim 5.
  • Gases and liquids in particular, for example, air and water, are not only contaminated by solid particles in dust or colloid form, but often also by chemical gaseous or dissolved substances.
  • cleaning method on the basis described in the two German patents mentioned, it has been possible in particular in multi-stage systems by specific preparation of the filter media of individual stages to effectively remove chemical gaseous or dissolved impurities. This is of great importance, for example, for paint shops, in welding shops, but also in commercial kitchens and in many other areas of the commercial economy, for example, from water purification to health care, where the sterilization of indoor air in surgery and intensive care units continues to be a major technical issue Represents problem.
  • the invention is therefore based on the object of specifying a new method for cleaning contaminated fluids, i.e. gases or liquids, and a cleaning device suitable for carrying out the method using a liquid wash, with which there is an outstanding cleaning action for a very wide spectrum of pollutants can be achieved in dust or colloid form as well as in gas or in dissolved form.
  • a device according to the invention for cleaning contaminated fluids has the features specified in claim 5.
  • the basic idea of the invention is to first atomize or spray a contaminated fluid (gas or liquid), to ionize the resulting, finely divided particles in a manner known per se by means of an electrostatic high-voltage field and then to electrostatically attach them to a likewise and preferably sprayed in the same direction of flow
  • the finely sprayed washing liquid particles of the upstream highs p annungsionisie- approximate device were charged to counter potential p ol for ionization ative.
  • a contaminated fluid F (gas or liquid) contaminated with pollutants is conducted via a line 1 under pressure to a first spray head 2 and atomized or sprayed in a tubular chamber 3, for example.
  • the resulting contaminated fluid flow is indicated with reference note 4.
  • This fluid stream 4 passes through a high-voltage ionization device, which is generally indicated with reference note 6 and which has, for example, a plurality of ionization wires 6A or saw blade-like wire elements which are tensioned transversely to the flow direction and which are tensioned between grid-like shielding walls 6B.
  • the high-voltage ionization elements 6A are, for example, at the negative potential of the high-voltage generator (not shown), which emits a high DC voltage of, for example, 12 to 100 kV with a relatively very low high-voltage output.
  • the shielding electrodes or walls 6A then lie on opposite, i.e. that is, to positive potential and are expediently connected to ground potential.
  • the ionized fluid stream contaminated with pollutants now arrives downstream of the high-voltage ionization device 6 in intimate mixing with a washing liquid kit stream 8 sprayed via a two spray head 7, which is at counter potential for ionizing the contaminated fluid stream.
  • the second spray head 7 is at positive potential, ie at ground potential, which, as indicated at 5, is applied directly to the spray head 7.
  • the surprisingly high cleaning effect of the process according to the invention is based primarily on the fact that the particles of the contaminated fluid stream, which are negatively ionized in the example shown, are held in place by electrostatic attachment and neutralization with the sprayed, counter-potential particles of the washing fluid stream 8 with a strong additional binding effect.
  • the cleaning effect is much better than with a pure liquid wash of a conventional type.
  • the washing liquid is kept ready and collected in a washing liquid container 16 in a manner known per se.
  • the washing liquid level 17 is kept constant by means of a level control which is only indicated schematically.
  • a thermostat 18 is used to control the temperature of the washing liquid, and fresh, unused washing liquid can be supplied via an inlet 15.
  • a pump 10 sucks the washing liquid out of the container 16 and presses it via a filter system 9 to the second spray head 7.
  • the feed pipe for the washing liquid flow 8 with already accumulated pollutant-laden fluid particles is identified by reference note 21.
  • a through in a manner known per se perforated plates realized turbulence brake 19 may be provided.
  • a drain solenoid valve 14 is provided, via which a pipe connection leads to a disposal or separation unit, only indicated schematically, the drain of which is designated by 12.
  • the cleaned fluid stream 24 is discharged for further use via an outlet pipe 23 and is simultaneously monitored and regulated with regard to certain parameters, for example with regard to its moisture content.
  • a hygrostat protruding into the outlet pipe 23 is identified by reference 22.
  • a heating jacket 20 can be used for temperature regulation, which can be implemented, for example, with Peltier elements, so that both heating and cooling of the cleaned fluid stream 24 is possible.
