Definitions

  • ABSTRACT Negative ions are generated by passing a stream of gas and water vapour free of water droplets through a corona discharge of 5,000 volts or more.
  • British Pat. Specifications Nos. 392,945, 414,687, 420,360 and 436,467 disclose methods and apparatus for electrically treating moist air, but the air stream produced by the apparatus in those cases, when operated as set forth in the specifications does not contain negative ions in stable form.
  • a method of producing negative ions which comprises passing a stream of gas and water vapour not containing any water droplets through a corona discharge of voltage at least 5,000 volts.
  • an apparatus for the production and. transport of negative ions which comprises means for producing a stream of gas and water vapour not containing any water droplets, a corona discharge gap, and means for blowing the stream through the corona discharge gap and exhausting it to atmosphere.
  • negative ions are generated which are not subjected to rapid recombination in clean dry air.
  • polluted air it is found that the generator clears the pollution, for example smells or mist.
  • the stream of negative ion containing air so produced is valuable in medical therapeutics for the treatment of pulmonary and respiratory conditions.
  • the present apparatus does not need to be directly in front of the mouth of the patient being treated the negative ion-containing stream of gas is stable and recombination rates are comparatively low.
  • the patient may accordingly be several feet away from the apparatus and yet be benefitted thereby.
  • the polarity of the room and contents in which the apparatus is operated may be changed from positive to negative.
  • the stream of gas which is passed through the corona discharge may contain components additional to air and water vapour, and by breathing the stream of air containing negative ions, these components may be introduced into the body.
  • the components which may be used in this way vary widely, but include elemental materials such as alkali, alkaline earth and other metals, and other chemical compounds which may be absorbed from the atmosphere by the lungs.
  • the voltage may be raised if desired to a value much above the 5,000 volt minimum, and this is of particular use in large ion generators such as might be used to condition a treatment room or even a complete hospital ward.
  • FIG. 1 is a side view of the apparatus
  • FIG. 2 is a top view.
  • the apparatus comprises a standard evaporator 1 (such as that sold under the Trade Mark MOULINEX) which has been modified by the addition of extra evaporator wicks 2. These wicks may suitably be made of filtration board, and their area must be sufficient to give adequate humidification.
  • This evaporator contains a fan which sucks in air from the atmosphere and slowly passes it over the wicks and exhausts it into a convergent channel 3.
  • a treatment tunnel 4 in the centre of which is located a pair of corona discharge electrodes, a lower spike negative electrode 5 and an upper semi-cylindrical positive electrode 6.
  • the lower electrode is mounted on a suitable high voltage generator 7, e. g., any suitable apparatus capable of producing a spike voltage of 7,500 volts.
  • the corona discharge current in apparatus of this type is preferably 20 to 30 microamps.
  • the outlet end of tunnel 4 is connected to a discharge vent 8.
  • the evaporator l is filled with water, preferably distilled or deionised water, and the fan set in motion.
  • the corona discharge isset up and it is found that after a brief period of settling down, measurable negative ion concentrations may be easily detected more than 20 feet away from the apparatus.
  • Theapparatus described above may be made ofany convenient material such as metal, plastics or fibreglass, but the preferred material of construction is wood.
  • an evaporator of such efficiency that, under the conditions of use, the relative humidity of the gas stream passing through the apparatus is raised by at least 5 percent.
  • Apparatus for the production and transport of negative ions which comprises means for producing a stream of gas and water vapour not containing any water droplets, a corona discharge gap, and means .for blowing the stream through the corona discharge gap and exhausting it to atmosphere.
  • the means for producing a stream of gas and water vapour includes a wick evaporator, said wick evaporator providing a large evaporative surface area from which the water evaporates to provide water vapour free of water droplets.
