Definitions

  • the invention relates to an air purifier of the regenerating type, which comprises a radiating means such as a.mercury lamp, and in which the air flows through an electric field in an electron-cloud forming member.
  • An air purifier comprising a mercury vapour lamp is known from, for example, British patent specification No. 1,400,519.
  • the irradiation with ultraviolet rays changes the nature of the passing pollutant.
  • the invention as claimed is intended to provide an air purifier which is able to sterilize air and neutralize the ozone molecules in a more efficient manner.
  • the air purifier according to the invention is characterised by the radiating means being surrounded by a charge absorbing, non-conductive casing.
  • the non-conductive casing is made of a soft, optionally plumbiferous plastic.
  • the air purifier according to the invention operates in accordance with the regeneration principle. It comprises a radiating means 1 such as a mercury lamp, emitting both electrons and X-rays.
  • a radiating means 1 such as a mercury lamp, emitting both electrons and X-rays.
  • the X-ray wave length is in the range of 300-400 nm.
  • a voltage of 8000 V the wave length range is increased to about 165 nm.
  • a destruction of DNA molecules and consequently a destruction of germs and viruses takes place.
  • a cell division takes place so quickly that the cells produced cannot survive.
  • the electron bombardment the oxygen, hydrogen and nitrogen bound to heavy molecules such as sulphur, chlorine or metals, are liberated.
  • the heavy molecules are detected and captured by the chamber material, while the liberated oxygen molecules produce ozone molecules. These ozone molecules are, however, positively charged due to the fact that the heavy particles detected and captured by the chamber material are negatively charged (the chamber material must be non-conductive).
  • An electron-cloud forming member preferably a capacitor-like member 4, is placed behind the radiating means 1, said member generating negatively charged 0 3 molecules. When a positively charged 0 3 molecule meets a negatively charged 0 3 molecule, the oppositely charged molecules recombine to produce 0 2 molecules.
  • the tension across the capacitor-like member 4 is for instance of the magnitude 8000 V, which,corresponds substantially to the voltage necessary for the radiating means 1 to emit X-rays having wave lengths down to 165 nm.
  • Fig. 2 shows a voltage multiplier M comprising a sufficient number of capacitors C mutually connected through rectifier diodes in such a manner that the charge can only be transmitted in one direction.
  • Fig. 2 only shows 10 capacitors.
  • the capacitor-like member 4 is composed of circuit carts 7 having metal coatings 7a and 7b on both sides. The surfaces of these coatings are suited for emission of electrons.
  • the number of plates 7 may be varied.
  • the surface area of each plate is 10 x 10 cm 2 .
  • the mutual distance between the plates is for instance 1 cm.
  • the casing 2 surrounding the radiating means 1 and the capacitor-like member 4 is composed of a soft, optionally plumbiferous plastic.
  • a separate plumbi- . ferous coating may also be provided on the outside of the casing 2.
  • a blower 3 is situated at an inlet opening 9 constructed in such a manner that radiation direct to the surroundings is impossible.
  • An air purifier with a power consumption of 80 W can treat 6 0 m 3 air per hour.
  • a choke coil is inserted between the output of the voltage multiplier M and the phase terminal.
  • the power supplied at the high voltage is relatively low. Furthermore, a DC-discharge from the multiplier only occurs at every other half wave of the voltage of the mains.
  • the air purifier according to the invention is inexpensive to produce.
  • the most expensive component is the casing.
  • the oxygen content in a room is increased no more than 6-8%.
  • the air purifier which may be varied in many ways without deviating from the scope of the invention, is mainly intended for aircrafts, automobiles or hospitals.
  • the purifier may, however, also be used industrially or in offices.
  • the air purifier improves the air for the employees. It is easy to mount, since it does not require ventilating ducts to the surroundings. Furthermore, no thermal loss occurs. In slaughterhouses it increases the keeping quality of the meat since only viruses and bacteria are killed.
