<p>PURPOSE:To make the dust collecting efficiency of a titled device higher and running cost less by connecting suction blowers provided to the roof of a building in the part lower than the inlet of the body of the dust collector and forced draft ducts having discharge ports near the inlet of the dust collector. CONSTITUTION:The air flow contg. the dusts having spread wider to a certain degree than main upward flow and the air flow contg. the dusts descending by stagnating and staying in the upper part of a building 1 are sucked by respective suction blowers 9 and are fed up to near the inlet right under the body of a dust collector 2. They are then blown into the main upward flow through their discharge ports 11. Since at this time the discharge ports 11 are opened upward, ejection effect may be utilized together with the buoyancy of the upward flow itself. Further, the charge power of the device 2 is controllable and since the operations of the respective blowers 9 are stopped or the speeds are controlled depending upon the dust generation conditions, running costs are reduced.</p> |
