上海第三钢铁厂中板分厂中板酸洗槽,在每天酸洗过程中,产生大量的硫酸雾及氮氧化物气体。这些气体不仅腐蚀厂房设备,而且也危害人体健康,严重污染环境。为解决这个问题,该厂通过试验研究,采用了由浙江玉环环保设备厂生产的《PPB》实心塑料球作覆盖剂及设计了一套投球、清洗、回收等技术设施。经试用生产一年后,设备运转正常,并对酸洗槽抑制酸雾效果显著,经环境监测部门测定,操作点的硫酸雾浓度由原来的6.13mg/m~3(没有治理措施)减少
Shanghai Third Steel Factory plate factory plate pickling tank, pickling process every day, resulting in a large number of sulfuric acid mist and nitrogen oxide gas. These gases not only corrode the plant equipment, but also endanger human health and seriously pollute the environment. In order to solve this problem, the factory adopted “PPB” solid plastic ball made by Zhejiang Yuhuan Environmental Protection Equipment Factory as covering agent and designed a set of technical facilities such as pitching, cleaning and recycling through experimental research. After a trial production of one year, the equipment is operating normally, and acid pickling tank inhibit the effect of significant acid mist, as determined by the environmental monitoring department, the operating point of the sulfuric acid mist concentration from the original 6.13mg / m ~ 3 (no control measures) to reduce
