Dust collector for gaseous fluids and a method for manufacturing the dust collector

A dust collector for removing dust from gaseous fluids containing fine dusts that originate from industrial processes, comprising:

• one or more filtering assemblies, each of which has a plurality of filtering elements extending in a tubular form, having a length and closed at one end, wherein:
• the filtering elements are made of a rigid or semi-rigid filtering material;
• at least some of the filtering elements are connected to each other with interposition of spacer sections, wherein the spacer sections are arranged on generatrices of the filtering elements so that parallel rows of filtering elements connected by spacer sections are formed, the rows extending parallelly to a first axis of a system of cartesian axes;
• the rows of the filtering elements of the same filtering assembly are kept in contact with each other along a direction parallel to the length of the filtering elements, the spacer sections extending along the entire length of the filtering elements that the spacer sections connect, so that laterally closed flow channels for the gaseous fluid extend longitudinally and are enclosed between the filtering elements and the spacer sections;
• the cross-sections of the filtering elements and flow channels define, as a whole, a cross-section of the respective filtering assembly as a two-dimensional repetition of closed geometric figures;
• the flow channels are open at one end and closed at a further end opposite the end at which the filtering elements are closed, and
• the dust collector further comprising a cleaning system for periodic automatic or semi-automatic cleaning of said one or more filtering assemblies.
