Definitions

  • the present invention makes use of the airflow- aligned, charged parallel plate principle and, optionally, the ionization principle in conjunction with polarized media to provide an improved performance filter.
  • Conductive surface portions may be formed on alternating sections of trapping medium constructed as a continuous surface folded into pleated panels by coating the medium with a conductive material, such as fine carbon or aluminum, preferably mixed with a binder. Conductive surfaces may also be formed by transferring conductive panels of conductive, porous (air-permeable) media to the trapping media as by an adhesive. With trapping media contained between polarizing electrodes, a high potential voltage source is connected to provide a polarizing potential difference between consecutive electrodes. This potential difference not only tends to polarize the intervening portions of the trapping medium but also creates an electrical potential field between the electrodes with a high field gradient. Dust particles, particularly charged dust particles, are drawn laterally in the air flow by this transverse field to contact and be retrained in the trapping medium.
  • a polarizable fiber matrix or the like may be inserted between the plates 3 as shown subsequently in Figure 7, below.
  • Figures 5 and 6 show a pleated filter wherein the pleat panels 19 are separated by lengths of beads 13 of glue applied to the filter media 2 before it is pleated.
  • the glue beads 13 keep the pleat panels 19 apart and at the same time make the filter self-supporting without any need for other structure, such as a screen.
  • the plates 7 or screens 20 need not be perfectly aligned, in parallel with the airflow 9. Such screens may be obliquely inclined to the direction of the entering airflow. In either case, the screens 20 receive the airflow 9 edge-on, as do the media sections 21. And the airflow 9 between the screens 20 passes in a direction which is parallel to the surface of the electrode (in the colloquial sense, and not parallel to the mathematical direction of such surface) .

Abstract

Cette invention se rapporte à un filtre du type précipitateur électrostatique, qui est combiné à un support de piégeage polarisable remplaçable. Dans l'un des aspects de cette invention, ledit support est placé entre des plaques polarisantes. Dans un autre aspect, le support est recouvert dans certaines sections, de façon à former une surface conductrice qui sert de plaques chargées pour le précipitateur. L'effet d'ionisation est de préférence produit par une série d'éléments ionisants, tels que des aiguilles ionisantes.
