铜冶炼熔炼车间环境集烟系统设计

Design of Fugitive Offgas Collection System in Copper Smelting Plant

铜冶炼工艺产生的烟气中含有SO 2及其他有害烟尘,导致熔炼车间的工作环境较差,很容易引起现场工作人员的职业健康问题。环境集烟系统对改善车间环境、减少职业病危害起到十分重要的作用。本文以某铜冶炼厂熔炼车间的环境集烟系统为例,介绍环境集烟系统的设计方案,包括烟气罩通风量的计算方法及车间内的气流组织方案,并通过侧吹炉排放口的测试数据,分析环境集烟系统运行过程中出现的问题。最后指出一个良好的工作环境,不仅需要完善的系统设计,还需要规范的现场操作。

The offgas produced in copper smelting process contains SO_(2) 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.
