硫酸装置净化工序高效湍冲洗涤器进液管、喷头改造实践

Modification of the inlet pipes and the spray nozzles of the high efficient scrubber used in the cleaning process for sulphuric acid plant

为解决冶炼烟气制酸净化工序一级动力波湍冲洗涤器FRP进液管断裂、聚四氟乙烯喷头滑丝及连接螺栓腐蚀严重、喷头脱落、喷淋压力骤降等问题,通过优化设计、降低制作及维修成本,解决了螺栓腐蚀、喷头脱落等顽疾,实现设备长周期稳定运行。

To solve the problems,such as the breakage of the inlet pipe of the FRP scrubber,the strip of the tetrafluoride spray nozzles and the severe corrosion of the joint connector bolts,the fall-off of the spray nozzles,and sudden spray pressure drop of the scrubber by the first order turbulent wave cleaning process of the sulphuric acid production via smelting flue gas,optimization design were carried out to reduce the operating and maintenance cost. Stubborn problems,such as the corrosion of the bolts and the fall-off of the spray nozzles,were solved.The long-term stable operation of the equipment has been achieved.
