冀州平板式脱硫塔的冲洗水压
除雾器水压一般根据冲洗喷嘴的特征与除雾器之间的距离等因素确定(喷嘴与除雾器之间的距离一般为650-900mm),冲洗水压低时,冲洗效果差。冲洗水压高则易造成烟气二次带水。同时降低叶片使用寿命。一般情况下,一级除雾器采用两层冲洗;及烟气的正面一层(除雾器对烟气的临界面)向上冲洗,水压为2.5-105pa以内,除雾器的背面一层向下冲洗,水压为1.5-105pa以内.二级除雾器采用一层向上冲洗,水压同一级同样。反面不冲洗,以免造成二次携带。具体的数值需根据工况情况而定。
冀州平板式脱硫塔为什么除雾达不到预期效果...
并不是所有的除雾器都是能达到预想的结果的,有的时候如果清晰不当的话也是会出问题的,比如所容易造成叶片的结垢的,造成FGD系统的整体瘫痪的。
一般如果除雾器除雾效果差的话会进入GGH的净烟气中有包含石膏颗粒或者是尘粒液滴的,这样会导致GGH的结垢堵塞的。
究其原因有几个方面的原因:
1.原烟气流经电除尘器后进入FGD系统烟气中的剩余粉尘。
2.经除雾器后净烟气携带的含有石膏颗粒及尘粒液滴在GGH受热面表面蒸发结晶的产物。原烟气中携带粉尘较易清除,且目前火力发电机组所配备的除尘器一般均能满足FGD系统运行需求。
综上所述,除雾器运营不当或者是除雾效果变差等都会造成湿法脱硫中GGH堵塞的,这是主要的原因。
Mist eliminator purpose
The demister is used to separate the liquid droplets of the gas entrainment in the tower, so as to ensure the mass transfer efficiency, reduce the valuable material loss and improve the operation of the post compressor, generally, the mist eliminator is usually set up on the top of the tower. The droplet of 3--5um can be removed effectively. If the foam eliminator is installed between the trays, the mass transfer efficiency of the tray can be ensured, and the space between the plates can also be reduced. So the demister is mainly used for the separation of gas and liquid. The air filter can also be used for gas separation. In addition, the screen can also be used as a buffer for various meters in the instrument industry to prevent radio wave interference.
