  • Patent number: 9254458
    Abstract: A filter including a filter housing with a horizontal partition wall dividing the filter housing into a dean-gas chamber and a dust chamber. The filter has an inlet part in open communication with the dust chamber. The inlet part is configured for supplying a dust-containing flow of gas to the dust chamber. The gas flow is conveyed through the filter elements and upwards into the dean-gas chamber where the filtered gas is discharged through a clean-gas outlet. In the filter housing, a cylindrical inner portion is arranged that encircles the filter elements. A round-going inlet part is opposed to the cylindrical inner part. The round-going inlet part has a larger diameter than at least a portion of the filter housing that adjoins the inlet part. Gas flow is divided into an upwardly and downwardly oriented gas flow controlled by arrangement of the cylindrical inner part.

  • Publication number: 20130067876
    Abstract: The invention relates to a filter comprising a filter housing, an inlet and a cylindrical inner portion. The inlet is configured for conveying a gas flow into the filter whereby the gas flow is conveyed around a gap between filter housing and inner part, said inlet configured for supplying a particle-containing gas flow to the filter through the filter elements and out through a clean-gas outlet.

  • Publication number: 20100077709
    Abstract: The invention relates to a filter (1) comprising a filter housing (2), an inlet (13) and a cylindrical inner portion (14). The inlet (13) is configured for conveying a gas flow into the filter whereby the gas flow is conveyed around a gap between filter housing (2) and inner part (14), said inlet (13) being configured for supplying a particle-containing gas flow to the filter (1) through the filter elements (7) and out though a clean-gas outlet (9). In the filter housing (2) a cylindrical inner part (14) is arranged that encircles the filter elements (7) at least across a portion of the length of the filter elements (7) and that, on the filter housing (2) opposed to the area where the cylindrical inner portion (14) is arranged, a round-going inlet part (8) is configured, which inlet part (8) has a larger diameter than at least a part of the filter housing (2) that adjoins the inlet part (8).
