The present invention relates to a filter dust collector for predusting, which can prevent fire or abrasion without a separate pretreatment facility by a pretreatment function of precollecting dust from a fluid which flows into a filter cloth. An existing filter dust collector comprises: an inflow duct (111) formed on the lower side of a dust collector body (110); at least one filter cloth (113) arranged and installed in the dust collector body (110); a clean air outlet (114) formed on the top of the dust collector body (110), where clean air in which dust has been removed through the filter cloth (113) is discharged; and a dust outlet (116) formed on the bottom of the dust collector body (110), where dust separated from the filter cloth (113) is discharged. The present invention relates to a filter dust collector (1) for predusting, which comprises: a perforated front plate (120) mounted on the front of the inflow duct (111) and having multiple perforated parts (121) formed in rows; and multiple dust collecting parts (130), each of which has a shape extended vertically, is mounted toward the other side of the perforated front plate (120) to be separated at regular intervals from the perforated front plate (120) so as to allow gas which has passed through the perforated parts (121) to collide, has side plates (131) on both sides, and operates to allow collected dust to fall downwards. |
