Exposure levels of oil mist particles under different ventilation strategies in industrial workshops

Oil mist particles emitted in industrial buildings are harmful to health. To evaluate the control effect of existing ventilation strategies on oil particles, this work conducts field investigations processing workshops different scales and processes. Through on-site measurements, basic characteristics mass concentration, quantity particle size distribution, technology, emission rate can be learned from angles. The article presents concept unit index, which provide reference data for design, as well input parameters simulation calculation. At same time, based air change rate, controlling was evaluated, relationship between concentration workshop investigated. In view uniformity workshop, influence process mode discussed. conclusions obtained used support optimizing pollution play a certain guiding role design evaluation buildings.
