Air cleaning devices for recirculation of exhaust air.

• Description:
  The characteristics of particulate, gas and vapor collector types are reviewed, and the factors influencing recirculation and the feasibility of recirculation are discussed. Particulate collector types include industrial air cleaners for removal of heavy concentrations of particulates and atmospheric air cleaners for removal of very light concentrations of atmospheric suspensions. Considerations involved in the gas and vapor collector types include incineration, absorption and adsorption. The savings from recirculated air from exhaust systems are shown to be a function of exhaust volume, plant location and operating hours. When and where to use monitoring and the notion of failsafe protection are discussed. Where climatic conditions indicate, recirculation of exhaust-system-cleaned air is considered to offer a substantial energy savings mechanism, especially in situations requiring clean exhaust air for air pollution control. Recirculation is considered least practical for systems handling fumes, smokes, vapors or gases.
