The offgas produced in copper smelting process contains SO₂ and detrimental dust, which leads to poor working conditions in the smelting plant, posing occupational health hazards to workers there. The fugitive offgas collection system is critical in improving work conditions and reducing occupational disease hazards. Taking as an example the fugitive offgas collection system in a certain copper smelting plant, this paper introduced the design scheme of fugitive offgas collection system, the calculation method of the ventilation volume of the offgas hood and the air distribution scheme in the plant building. It also analyzed the problems in the operation of the fugitive offgas collection system through test data of the vent of the side-blowing furnace. Finally, it pointed out that to ensure working conditions requires both sound system design and standard field operation.
