硫酸锌工艺制取过程因产生砷化氢引起急性中毒。在其车间安装了局部自然排风设备,使砷化氢浓度从30～50mg/m~3降至0.13mg/m~3,再无中毒发生。排风效果明显。 为防止中毒,确保职工健康,该厂在硫酸锌车间安装了局部自然排风设备。为探讨设备的排风性能,进行了效果评价。
Zinc sulfate production process due to the production of arsine caused acute poisoning. In its workshop to install a local natural ventilation equipment, the concentration of arsine from 30 ~ 50mg / m ~ 3 down to 0.13mg / m ~ 3, no poisoning. Exhaust effect is obvious. In order to prevent poisoning, to ensure the health of workers, the plant in the zinc sulfate workshop to install a partial natural exhaust ventilation equipment. In order to explore the exhaust performance of the equipment, the effect was evaluated.
