焦炉集气管压力自动调节的改进

Improvement on the Automatic Regulation for Gas Collecting Main Pressure

改变调节系统的取压点,应用快速阻尼器克服系统干扰,通过对鼓风机进行变频调速,实现了焦炉集气管压力的自动调节。

The automatic regulation of the pressure in the gas collecting main of coke oven is realized by changing the pressure measuring point of the regulating system,applying a quick damper to overcome the system interference and setting the PID parameter of regulator through the system,at the same time,frequency conversion speed regulating technology is adopted on the exhauster.
