Title: Building dust collection
Inventor: YASUNAGA MASAAKI
IPC: B08B15/00
Filed: 1993-03-25
Abstract: PURPOSE:To collect dust in a building such as an electric furnace operates at a low running cost by allowing a mounted suction fan to such metal fume so that the fume is sent into a dust collection chamber nearby using a ceiling crane which travels at a metal fume generation site in a building, and further allowing the metal fume to pass through a dust collection filtration part installed in the dust collection chamber. CONSTITUTION:The building collection method is to move a ceiling crane with a mounted suction fan 6 so that the fan 6 is positioned above ascending metal fume 8, when the metal fume 8 is released into a building 1 during scrap feed or steel spouting at an electric furnace works. Then, the metal fume 8 which ascends is sucked by the suction fan 6 into a nearby dust collection chamber 4 before the metal fume 8 does not become dissipated. Further, the metal fume is allowed to pass through a dust collection filtration part 5 for the collection of the fume 8. Consequently, the suction air volume for sucking the metal fume is small and thereby the volume of an air discharged for dust collection 15 is small. Thus running cost for dust collection can be reduced.
