Abstract
A filter element for filtering impurities from air, whereby the filter element comprises one or more filters, whereby each filter is composed of a filter frame that is connected to a filter bag, characterized in that the filter frame and the inflow opening of the inlet piece have an aerodynamic design and that the filter bag is essentially cylindrical of which the one end is open and fastened to the inflow opening and the other end is closed.
Claims17
A filter element for filtering impurities from air, the filter element comprising one or more filters,
- wherein each of the one or more filters is composed of a filter frame that is connected to one or more filter bags, wherein the filter frame comprises one or more inflow openings through which air with said impurities to be filtered flows, and each of the one or more filter bags includes a first end which is open and fastened to the inflow opening and a second end which is closed;
- wherein each of the one or more filter bags respectively extends in length along a longitudinal direction of the respective filter bag and has a diameter that is substantially perpendicular to the longitudinal direction of the respective filter bag, wherein each of the one or more filter bags defines a continuous inner chamber that extends from the first end to the second end, and the diameter of each of the one or more filter bags changes along the longitudinal direction of the respective filter bag;
- and
- wherein filter bag includes a first part, a second part, and a third part,
- wherein
- the first part extends from the inflow opening to a first point at a first distance along the longitudinal direction of each of the one or more filter bags, wherein the diameter of the filter bag along the first part is constant or approximately constant,
- the second part extends from the first point along the longitudinal direction of each of the one or more filter bags to a second point at a second distance along the longitudinal direction of each of the one or more filter bags, wherein the diameter of the filter bag along the second part decreases, and
- the third part extends from the second point along the longitudinal direction to a third point at a third distance along the longitudinal direction of each of the one or more filter bags, wherein the diameter of the filter bag along the third part increases, and
- wherein the first part, the second part, and the third part are arranged along the continuous chamber between the first end and the second end.
