Abstract:
A filtration installation including a time delay device which, at the time of a filter sleeve cleaning operation, establishes a cycle to exhaust filtered air towards the outside atmosphere instead of recycling it. The installation also includes a device for bypassing the filtered air that includes two shutters. One of the shutters controls a recycling of the filtered air and the other shutter controls the exhaustion of the filtered air to the outside atmosphere. These shutters are actuated via a control device under the control of time delay device
Abstract:
Process and apparatus for filtering air in a cyclone filter by reducing the ascending speed of air to be filtered in the lower part of the filter by providing a skirt on the filter cartridge. Perforations are included in the skirt, which make it possible to increase the intake surface for the air at the lower intake of the skirt. Moreover, the diameter and density of the perforations are adapted according to the type of dusts and wastes suspended in the air.
