滨州脱硫除雾器叶片间距
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。
滨州脱硫除雾器冲洗系统设计标准和性能
冲洗喷嘴是除雾器冲洗系统中重要的执行部件。对于每一款的喷嘴,我们在工程应用之前都进行可行性分析,在模拟的环境中进行喷洒分布分析、喷射冲击力测量、喷洒液滴尺寸分析、喷洒角度测量和材料磨损试验,通过建立数学模型选择喷嘴的喷射压力和喷射角度,以及相邻喷嘴的间距,以达到冲洗效果。
Mist eliminator Blade spacing
The size of blade spacing has great influence on defrosting efficiency of mist eliminator. With the increase of blade spacing, the efficiency of mist removal is reduced.
The increase of the inter plate distance makes the particle size in the channel larger, and the velocity direction of the air flow tends to be slow, which makes the particle to follow the air flow better, and is easy to flow out of the blade channel with the air flow and not be captured, so the effect of mist removal is reduced. The selection of mist eliminator blade spacing is very important for ensuring the fog removal efficiency and maintaining the stable operation of fog removal system. Large blade spacing, low mist removal efficiency and serious water flue gas lead to the failure of the induced draft fan and heat exchanger, resulting in the abnormal shutdown of the whole system. When the blade spacing is too small, the efficiency of external energy consumption is reduced, and scaling and blockage on the blades will cause the whole system to be shut down. The blade spacing was selected according to the comprehensive characteristics of flue gas characteristics (velocity, SO2 content, dust concentration with water load), absorption and utilization rate, and leaf structure. At present, the spacing between the blades of the demister commonly used in the desulfurization system is between 25-40.
