A liquid barrier is disclosed that comprises a porous hydrophobic material which allows the flow of gases (e.g., corrosive gases) but inhibits the flow of liquids, including aqueous liquids. A specific embodiment of the invention relates to a venturi which incorporates a liquid barrier that allows the flow of gases (e.g., ozone and air) but inhibits the flow of liquids. Another specific embodiment of the invention relates to an ozone generation system that includes an ozone generator and a liquid barrier made of a porous hydrophobic material, which allows the flow of ozone but inhibits the flow back of liquids to the ozone generator. The invention also encompasses methods of introducing a gas into an aqueous liquid, wherein the gas passes through a liquid barrier prior to being introduced into the aqueous liquid.
L'invention concerne une barrière contre liquide comprenant un matériau poreux hydrophobe permettant à des gaz (par exemple, des gaz corrosifs) de s'écouler mais inhibant l'écoulement de liquides, notamment des liquides aqueux. Un mode de réalisation spécifique de l'invention concerne un diffuseur renfermant une barrière contre liquide permettant à des gaz de s'écouler (par exemple, de l'ozone et de l'air) mais inhibant l'écoulement de liquides. Un autre mode de réalisation spécifique de l'invention concerne un système de génération d'ozone comprenant un générateur d'ozone et une barrière contre liquide conçue dans un matériau hydrophobe poreux permettant à l'ozone de s'écouler mais inhibant le reflux de liquide dans le générateur d'ozone. L'invention concerne enfin des procédés permettant d'introduire un gaz dans un liquide aqueux, le gaz passant à travers une barrière contre liquide avant d'être introduit dans le liquide aqueux.
