For the extraction and the removal of carbon fiber powders that develop from 4 machine tools a system was built as follows: some suction hoses of suitable diameter are positioned behind the machines in order to remove the pollutant directlyfrom where it originates from. The flow is shared among the 4 machines according to their volume.
The suction hoses are then connected to a main manifold which conveys the pollutant to a AIRCOMPACT cartridge filter. The dusty air is drawn in, below the filter cartridges, through the inlet chamber connected to the hopper. The dust contained in the extracted air, due to the considerable decrease in speed, precipitates in the collection container and is then conveyed to the filtering cartridges passing from the outside to the inside, thus depositing impurities and returning the purified air. During the work, the filter is kept perfectly efficient, through a counter-current cyclic cleaning system. A jet of compressed air, accumulated in a special tank, is suddenly injected inside the cartridge, creating a violent countercurrent shaking wave, able to detach and to precipitate the particles deposited on the outside of the cartridges. A high performance centrifugal electrical exhauster creates the necessary vacuum and conveys the filtered gas into the air through the exhaust stack.
