Title
(EN) FLOW OPTIMIZED FILTER
(FR) FILTRE À ÉCOULEMENT OPTIMISÉ
Abstract
(EN)
A gas filtration system includes an inlet to allow gas to enter the system, an outlet through which gas leaves the system, and a filter that includes a filter media that defines a hollow inner region into which gas enters as it flows from the inlet to the outlet. The system also includes a flow straightener disposed between the inlet and the hollow inner region such that a flow path of the gas passes through the flow straightener before it enters the hollow inner region. The flow straightener can be in the filter or upstream of it.
(FR)
Un système de filtration de gaz comprend une entrée pour permettre au gaz d'entrer dans le système, une sortie à travers laquelle le gaz quitte le système, et un filtre qui comprend un milieu filtrant qui définit une région interne creuse dans laquelle le gaz entre à mesure qu'il s'écoule de l'entrée à la sortie. Le système comprend également un redresseur d'écoulement disposé entre l'entrée et la région interne creuse de telle sorte qu'un chemin d'écoulement du gaz passe à travers le redresseur d'écoulement avant qu'il entre dans la région interne creuse. Le redresseur d'écoulement peut être dans le filtre ou en amont de celui-ci.
