Abstract: The present invention relates to the field of filter system technology, and to a dust removal filter cartridge. The dust removal filter cartridge comprises: a filter material; and a filter net disposed within the filter material. An upper cover is disposed at a top end of the filter material, and an air outlet is provided at the upper cover. A lower cover is sealed at a bottom end of the filter material. A strap is disposed inside the filter material, and the strap is adhesively fixed on the filter material. An outer surface of the filter material is an effective filter surface for removing dust. The strap is disposed on the inside of the filter material, and since the filter area on an outer surface of a filter paper is increased during the dust removal process, the filtering effect is excellent. In addition, since the axial direction of the filter material is flat, there is insufficient support for dust in the axial direction of the filter material, which reduces the agglomeration of dust at the strap position, increasing the filter air volume and reducing the air resistance of the filter airflow. In addition, when the dust is cleaned by pulse-spraying from the inside of the filter material to the outside and blowing air in a reverse jet airflow, the dust is less accumulated, the air resistance of dust cleaning is small, and the maintenance cost is low.
