A pressure-type filter bag detection system for used filter bags includes a first conveying platform, a cage, and an air pipe. The first conveying platform has a through hole, and the cage is vertically connected to the inner wall of the through hole. The cage is a cylindrical structure with openings at the top and bottom, and its shape matches that of the filter bag. Multiple sets of detection devices are axially arranged on the outer circumference of the cage. Each set of detection devices includes a detector, an optical fiber, and multiple gratings mounted on the optical fiber. Gratings are placed between adjacent reinforcing bars in the cage. The optical fiber is wound around the outer circumference of the cage, and the detector is connected to one end of the optical fiber. The air pipe is positioned relative to the upper end of the cage. This design can not only determine the degree of damage to the filter bag but also easily locate the position of the damage.
