Abstract
In order to improve the current situation of the concentration of toluene and other toxic substances in the paint shop painting process, it provides a basis for the rational design of the push-pull ventilation in the paint shop. In this paper, a large painting workshop of a shipyard was taken as the research object. Using CFD numerical simulation analysis technology, research the control effect of the combination of blowing and suction ventilation and local air supply on toxic substances. Under the conditions of different air supply velocity, the influence of the size of the annular air exhaust on the airflow organization around and inside the workpiece is studied. The results show that when the size of the air exhaust is larger than 2.5 m of the worktable, the velocity of the internal section of the workpiece is greater than 0.5 m/s, and there is no vortex in the local air supply side. At this time, the air distribution in the workshop is good, and the toxic substances in the workshop can be effectively discharged, can effectively enhance the ventilation effect of large painting workshop.
