<p>PROBLEM TO BE SOLVED: To provide a backflow type granular material filter device having a fiber filter for removing granular material from exhaust gas discharged from an engine. SOLUTION: This device has a controller 5 for collecting and outputting information signals, a metal fiber filter 2 for collecting granular material in exhaust gas, a back pressure sensor 3 for detecting gas pressure differential across the filter 2, a compressed air feeding part 10 for receiving signals from the controller 5 and jetting compressed air to the metal fiber filter 2 to remove the granular material, a collecting box 19 for collecting the removed granular material, a collecting valve 15 for guiding the granular material to the collecting box 19, and the like. In this way, the life of the filter is prolonged, and the structure of the device is simplified to improve assembling productivity and increase exhaust gas filtration efficiency.</p> |
