Definitions

  • the hose(s) 110 exit toward the mask side of the respirator unit 200 to provide purified air to the wearer. Adjustments in the diameter of the hoses 110 as well as the total volume of the hosing unit can be made to increase transit time through the hosing circuit 110 to increase UVC exposure, maximize contact to the positive ion plate(s) 206, and improve breathabihty. Modifications to the hose 110 configuration to create a larger gravity trap can also be employed to enhance particle/pathogen capture and exposure.
  • Air flow into the circulation chamber 110 can include several embodiments.
  • the vents open to a glass air tube of the circulation chamber 110.
  • the side of the tube 110 facing the UV-C light is transparent or clear.
  • the side of the tube more distant from the UV-C source can be coated with a reflective positive ion plate 206.
  • the positive ion plate 206 can be inside or outside the tube 110.
  • Each air tube from an intake vent converges in a chamber near the inferior portion of the respirator where the collector plate(s) 206 will end.
  • the configuration of the glass at this end of the tube 110 maximizes air contact with collector plate(s) 206.

Abstract

L'invention concerne des systèmes et des procédés de purification de l'air. Les systèmes comprennent, par exemple, des masques et d'autres équipements de protection pouvant être portés. Les systèmes et les procédés comprennent, par exemple, l'application d'une ou de plusieurs contraintes à des agents pathogènes aéroportés et autres qui les rendent affaiblis, morts ou autrement désactivés. Les contraintes selon l'invention peuvent comprendre, par exemple, de l'énergie électromagnétique (par exemple, des ultraviolets, des infrarouges, des micro-ondes et autres) et/ou des agents antiviraux/bactériens dérivés de sources naturelles et/ou synthétiques, l'ionisation et autres. Les procédés peuvent également comprendre un ou plusieurs pièges ou filtrations comprenant des pièges à particules, électriques et/ou magnétiques (par exemple, des pièges à ions). Les systèmes comprennent un équipement de protection personnel tel que, par exemple, des masques et des respirateurs. Les systèmes comprennent également des unités de stérilisation permettant la réutilisation de l'équipement.
