Abstract
The double-side single-slit symmetrical push-pull grooved exhaust hood (DSPGEH) has better pollutant control performance than the traditional push-pull groove-side exhaust hood (TPGEH), and the airflow of DSPGEH is easily disturbed by the non-polluting airflow in the middle part of the industrial slot, resulting in gaps when the airflow is blocked, and thus pollutant escape occurs. In this study, different air blowing speed and pollutant emitting speed of DSPGEH are investigated. The double-side double-slit symmetrical push-pull grooved exhaust hood (DDPGEH) was proposed and its effect of pollutant sealing and energy saving was investigated. The results show that the mixed airflow used in the DDPGEH air supply airflow can effectively seal the pollutants in the working area of the exhaust hood. Compared with TPGEH, the energy saving rate of DSPGEH is 80.23% and that of DDPGEH is 96.70%. This study provides a new reference standard for the operation parameters of push-pull exhaust hoods and new ideas for the optimization of push-pull exhaust hoods.
