Abstract
A vapor clarification system includes a suction box and a plurality of fans located on top of the suction box. The fans withdraws a moisture-laden stream from the suction box and centrifugally accelerates it, producing a clarified vapor stream and a secondary vapor stream that is heavily laden with particulate matter. The secondary vapor stream leaving each fan passes through a cyclone, where particulate matter falls out of the vapor stream. The partially clarified vapor stream leaving the cyclone is returned to the suction box and re-accelerated in the fans. By placing the fans on top of the suction box, there is a reduction in the temperature drop occurring in the vapor stream which exits the fans; this in turn reduces condensation and improves the efficiency of the system. Primary cyclones are preferably disposed within the suction box, and secondary cyclones may be placed outside of the suction box. The number of fans can also be modified to meet varying system requirements, thus providing a more flexible air-clarification system.
