【 摘 要 】

This paper proposes a push-pull airflow combined with a top draft hood to conduct local exhaust in a rubber workshop. Field measurements are carried out to investigate the characteristics of the emission source, while numerical simulation is performed based on the measurement to test the capture efficiency and to further optimize various parameters including push velocity, hood height and exhaust air rate. Compared with the high-hanging hood, the low-hanging hood can effectively capture the pollutant generated by tyre with lower exhaust air rate. The capture efficiency of the low-hanging hood reaches 98.18% with exhaust air rate of 6000 m3/h and push air velocity of 5m/s. The results indicates that the new ventilation appliance can effectively collect the pollutant at a relatively low exhaust rate.
