优化SO_2风机入口导叶控制

Optimization of SO_2 Blower Inlet Guide Vane Control

铅锌公司投产初期,硫酸SO2风机入口压力低低报联锁停车数次,影响了工厂的顺利生产。SO2风机每次停车之后再启动至少需要2h以上的准备时间,若停车时间过长甚至需消耗天然气开启硫酸升温预热器,用以维持转化器内温度。故通过设计优化SO2风机导叶控制系统程序,优化导叶和入口压力间联锁程序,保证SO2风机正常运行,从而确保工厂的顺利生产。

In the initial stage of Lead and Zinc Company production, SO2 blower inlet pressure low sulfate interlocking parking several times in Sulfuric acid plant, affect the smooth production of the factory. The restart after SO2 blower each stop needs at least two hours for the preparation. If the stopping time is too long, it even needs to start the natural gas to warm pre heater sulfuric acid plant, to maintain the temperature in converter. So, through optimizing the design of SO2 fan vane control system program to realize optimization of guide vane and guide vane control system interlocking program between the inlet pressures, keep the normal operation of the SO2 fan and ensure the smooth production of the factory.
