Pellet powder aspiration system
Aspiration and filtration system for bagging operations
- Type of system: Suction of dust pellets
- Air flow: 50.000 m³/h
- Filter Type: Cartridge filter AIRCOMPACT ATEX
- Fan: PR 1000/4 – 75 kW
A system for the extraction and filtration of pellet dust, produced from bagging operations, was built as follows: 10 suction points distributed over 3 hoppers for loading of material, have been positioned in order to allow a correct suction of all dust and to prevent its dispersion in the environment. The suction stacks of suitable diameter are positioned behind the area affected by the discharge in order to remove the contaminant directly from where it originates from. A main pipeline conveys the contaminant to a AIRCOMPACT ATEX cartridge filter, with compressed air automatic cleaning. The filter is further provided with safety panels.
This protection allows to put the parts at risk of explosion in such condition that when a detonation occurs, their destructive power is directed to a “safety” area. A FLAP isolation valve provides an additional level of safety in order to prevent the propagation of an explosion through the ducts. An ATEX high performance centrifugal electrical fan creates the necessary depression and conveys the filtered gas in the air through the exhaust stack.
For the aspiration and filtration of VOC deriving from a paint machine, the following system has been realized.
Extraction and air treatment system from storage and treatment areas of biological sludge, flow rates up to 70,000 m³ / h.
For smoke collection of three coal-fired boilers 3 AIRCOM sleeves filters were installed with demister, with a total treated air flow of 185,500 m3 / h.
