Title Centralised exhaust system for cleaning extracted air (gas) with high concentrations of dust
Original title Centralizovannaja vytjažnaja sistema dlja obespylivanija aspiracionnogo vozduha (gaza) s vysokimi koncentracijami pyli [in Russian]
Bibliographic information May 1983, No.5, p.51-53. Illus. 7 ref.
Abstract Description and drawing of a centralised dust-collecting system for an ore-crushing plant. 5-6 local exhaust hoods are connected in sequence to a plenum chamber, a tube coagulator and a cyclone/scrubber unit; 3 cyclones are connected to a single central fan, which exhausts through a stack. Such a system can move 165,000m3 air/h while reducing the dust concentration from 5-6g/m3 to 0.08-0.1g/m3. Whereas current systems with this level of performance consume electricity at a rate of 1.0-1.1kWh/1000m3, the centralised system consumes only 0.7-0.8kWh/1000m3.
