Definitions

  • the present invention relates to an air ionization technique, and more particularly to an oxygen ion generation technique for use in an air purification apparatus. Background technique
  • the principle of tip discharge is used to ionize the air near the tip.
  • the positive pole is generally sharper (stainless steel needle or specially processed tungsten needle), and the negative electrode is made of flat plate, polygonal hole and round hole. Due to the oxidation of the tip of the needle at high pressure, it is quickly passivated. The reduction of the curvature of the surface increases the barrier of the electrons from the metal surface. To maintain its continuous discharge, only the voltage can be increased, and the voltage is too high. The tip of the needle produces more ozone and forms nitrogen oxides, which are harmful to human health and equipment safety. Therefore, this method is rarely used in the field of building air purification;
  • the conductive fiber bundle end is discharged in a virtual negative state, which is a deformation of the former method, and is generally used for a negative ion generator;
  • the surface of the large curvature of the thin round metal wire is used to discharge the inner surface of the flat plate, the polygonal column hole and the cylindrical hole, which is derived from the principle of electrostatic dust collection of the boiler, although the ion concentration near the electric field is large, Due to the restraint mechanism of the negative pole of the electric field, it is difficult to inject a large amount of positive and negative ions into the indoor air;
  • the surface of the large curvature of the thin round metal wire is discharged to the concentric mesh arc surface.

It has a very positive significance for building purification.
  • the device cannot generate a large amount of positive and negative ions in a short period of time, and the air purification effect cannot be achieved quickly in a building environment with poor indoor air quality. If the voltage is increased and the modulation is close to 3000V, more ozone will be generated.
