Abstract
Die vorliegende Erfindung betrifft einen Luftbefeuchter sowie ein Verfahren zum Befeuchten von Luft, wobei durch den Einsatz spezieller Vorrichtungen die Befeuchtung von Luft mit keimfreiem Wasser ermoeglicht wird.

 

DE 19910441 C UPAB: 20000801 NOVELTY - A membrane contactor (1) constitutes an air humidifier and has at least one tube membrane (5) embedded in a hydrophile porous body (3). This body can be of ceramic, polymer or fabric preferably of porous thread material with a hydrophilic surface. The pores (7) of the hydrophilic porous material have a diameter of less than 5 mm. DETAILED DESCRIPTION - The tube membrane is a micro-filtration hollow fibre or tubular micro-filtration membrane. The pores of the membrane have a diameter of less than or equal to 0.2 micrometers. The tube membrane has an inner diameter of 200 micrometers up to approximately 16 mm. An INDEPENDENT CLAIM is included for a method of aseptic humidification of air. USE - As an air humidifier. ADVANTAGE - The humidifier has a large contact surface from water to air and low from pressure loss.
