Order to better control pollutant discharge and environmental temperature control,on the premise of meeting the design requirements,this paper appropriately simplified the heat source and dust discharge in the actual plant based on the actual engineering conditions,combined with the computational fluid dynamics(CFD)method,coupled with the temperature and pollutant diffusion model,and simulated the operation of the air supply duct in the industrial plant.The influence of the release of welding smoke on the distribution of flow field,temperature field and dust concentration field in the whole industrial plant is analyzed.The results show that with the deterioration of the operating conditions of the air supply duct,the resistance of the air supply duct continues to increase,the air supply volume decreases correspondingly,and the ambient temperature and dust concentration get higher and higher,which directly affects the health of the staff.On the premise of ensuring that the working environment of the staff meets the national standards,the minimum value of the air supply duct in the factory is determined,that is,the best time point for back blowing.
