ABSTRACT:
A pollution control system for reducing the presence of fine aerosol particles in stack gases from the manufacture of glass fiber wool-type products. After larger particles are removed from the forming fan gas, the gas is fed into a centrifugal fan and massive quantities of water are injected into the fan intake. The aerosol particles are agglomerated by impact with the airborne water droplets and the wet surfaces of the fan. The larger, coalesced or agglomerated particles are more readily susceptible to inertia-type separation from the air by either the action of the fan or in a later separation operation. The massive volumes of water which are required to be injected into the fan for optimum particulate removal tend to accumulate in the fan housing, and the present invention utilizes one or more stripping slots in the fan housing which make use of the kinetic energy of the wash water as it travels along the inside surface of the fan housing to positively strip the wash water from the interior of the fan housing and into a water shroud to gravity drain the wash water into a hopper or the like.
