FILTER ENTERTAINMENT WITH A VARIOUS CLEANING CLEANING CHANNEL WITH INDIVIDUAL DIFFERENCES

摘要

A filter device includes a housing with an end part and a side wall and containing an axially arranged array of filter elements, such as ceramic elements. An inlet in the end part supplies fluid to the filter elements and an outlet in the side wall is provided for transporting filtered fluid from the housing, the side wall of the filter device being provided with a cleaning duct for supplying cleaning fluid to the filter elements via the side wall. The cleaning duct 6 includes a distal channel portion 15 having a relatively small diameter D1 and a proximal portion 16 adjacent the side wall having a relatively large diameter D2. A number of partitions 36, 37 extend in the proximal portion from a position at or near the sidewall towards the distal channel portion 15 at an angle (β) to a center line 20 of the cleaning duct 6.
