三沙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。
我公司是国内生产除雾器的专业生产商,具有开发,设计,制造除雾器的专业技术人员,我公司生产的除雾器质量可靠,除雾效率高,尤其在处理较细雾粒时,其除雾效率明显**丝网除沫器。

客户案例:
在2017年5月5日黑龙江的王经理在我公司购买一批玻璃钢除雾器。
客户评价:
我也是**接触这种新型的复合材料,自从在网上看见了荣驰玻璃钢除雾器,也多次咨询他们的售后,他们也根据我的实际情况,给我推荐了合适的产品,提供了一些设计方案。在价格,质量和服务都让我非常满意。
Mist eliminator What is the working principle of the demister?
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 mist droplets of 3--5um can be effectively removed. If a mist eliminator is installed between the trays, the mass transfer efficiency of the tray can be ensured, and the space between plates can also be reduced. The mist eliminator works parallel to the cross section of the tower. The flue gas is vertical through the demister channel, and the moisture and solid substances contained in the flue gas are removed during the modification process of the corrugated plate, so as to achieve the purpose of purification.
