ABSTRACT:
A gas dust-removing or dedusting filter of the kind incorporating a filter casing, filter tubes or bags having a flattened oval cross-section, and internal spacing elements. The casing includes a vertical partition having perforations and dividing the casing into a pure or clean gas chamber and a gas dust-removing chamber. The tubes or bags are horizontally insertable into the dust-removing chamber through the perforations of the partition and are sealed at their open ends to the clean gas side of the partition while their closed ends are supported on the rear wall of the casing.
In accordance with the invention, parallel vertical guide members, each having a surface which slopes with respect to a rear wall of the casing, are secured to the inner side of the rear wall of the casing. One guide member is disposed between two adjacent filter tubes or bags. The filter tubes or bags rest on support bars adjacent the rear wall of the casing, which engage said guide members. Also, the projection of each sloping surface on the rear wall corresponds to the spacing between two adjacent filter tubes or bags. The guide members prevent or minimize twisting of the tubes or bags.
