During welding operation

a large amount of metal dust is generated during the fusion welding process. These dusts exist in the air in the form of aerogel

which seriously affects the environment. At the same time

the dust is an easily inhaled substance

which is harmful to the human respiratory system

skin

eye blood

etc.

and seriously affect the health of workers.This article takes the actual workshop welding fume treatment project as the object

and studies the airflow organization form of the welding fume treatment system of tall workshops. Calculate and verify the rationality of the piping layout of the dust removal system with the aid of airflow simulation. At the same time

through the simulation data at different cross-sections

the blind spots of smoke and dust control are found

so as to determine the best air flow organization form and provide a reference for project design.
