ABSTRACT:
An apparatus especially suitable for filtering out a particulate material from a carrier fluid such as flue gases, as disclosed herein. This assembly utilizes a main vessel defining an interior compartment having an inlet and separate outlet. A number of filter assemblies are disposed within the vessel compartment and supported therein in spaced relationship with one another and with the vessel itself by means of a tubular member which also serves as a discharge pipe between the filter assemblies and the vessel's outlet. The main vessel is designed to act as an elementary cyclone so that filtering is carried out by both the filter assemblies and cyclonic action. Also, such filters are periodically cleaned by an arrangement that provided preheated reverse pressure pulses.
