摘要
Abstract
Due to the location of the source of fumes from the casting process is not fixed,the source intensity varies greatly and the implementation of pollution gas capture space location is insufficient,which has become a difficulty to create an occupational health environment in the foundry.A set of aerial mobile flue gas capture hood is designed.Numerical simulation is used to study the factors affecting the trapping efficiency.The results show that the addition of the capture hood can increase the wind speed in the capture range to about 0.1 m/s.The best trapping effect is achieved when the air velocity is 2 m/s.And 19.7％increase in particulate matter capture rate at a source temperature of 200 ℃ compared to 800 ℃,9.9％increase in particulate matter capture rate when the source is located directly underneath the capture hood compared to the capture rate at 4 m to the side.The capture rate of particulate matter at 1 m diameter of the source is 35.8％more than that at 3 m diameter.This study can provide parametric support for the engineering application of aerial mobile trapping hoods in foundries.关键词
