简阳平板式脱硫塔叶片间距
叶片间距的大小,对除雾器的除雾效率有很大影响。随着叶片间距的增大除雾效率降低。
板间距离的增大,使得颗粒在通道中流通面积变大,同时气流的速度方向变化趋于平缓,而使得颗粒对气流的跟随性更好,易于随着气流流出叶片通道而不被捕捉,因此除雾效果降低。除雾器叶片间距的选取对保证除雾效率,维持除雾系统稳定运行至关重要。叶片间距大,除雾效率低,烟气带水严重,易造成引风机、换热器故障,导致整个系统非正常停运。叶片间距选取过小,出加大能耗外冲洗的效率也有所下降,叶片上易结垢、堵塞,也会造成整个系统停运。叶片间距根据系统烟气特征(流速、so2含量、带水负荷粉尘浓度)、吸收利用率、叶片结构等综合因素进行选择。目前脱硫系统中常用的除雾器叶片间距25-40之间。

What is the Mist eliminator security factor?
The safety factor is the basis for the selection and use of equipment. In the future, if there is a need to use or choose the demister in the future, the key is to leave enough time, to compare carefully in the market, to select and purchase performance and quality guarantee, to design a reasonable, regular and high quality mist eliminator.
Safe use and protection will bring fog to us while the safety of the equipment itself can not be ignored. Whether it is the components of the parts, or the structure and design of the basic, we may well know more before we choose and buy, not to buy expensive products, only to choose the kind that can meet the needs of our application.
Excellent performance, greater adaptability to the environment, and so on, are all the mist eliminator can help us. Construction and installation is not a standard. It is also a key factor that can not be ignored for normal use.
To strengthen the maintenance of mist eliminator, the parts that have been seriously damaged and lose their value will be replaced in time. Cooperation with the relatively good after-sales service manufacturers can ensure timely treatment and regular maintenance.
