针对特定的反转式电旋风除尘器中的固体颗粒,把颗粒的整个收集过程分成4个区域,分别进行颗粒的凝聚机理分析,并通过冷态实验证实颗粒凝聚的规律性。理论分析与实验证明,电旋风除尘器中颗粒的凝聚存在如下结论:不同种类颗粒凝聚规律有所不同;处于除尘器不同区域颗粒的凝聚机理也不尽相同;荷电电压提高和给粉浓度增加能使颗粒凝聚作用加大,收尘效率提高;颗粒的强烈凝聚加强了离心分离作用,成为电旋风除尘器高效除尘的重要原因。
Theoretical analysis and experimental research are carried out in depth on principle and main influences of particle agglomeration in electrocyclone.According to analysis and test,the particle agglomeration is relative to intrinsic factors which means primarily particle adsorptive and charging characteristic and extrinsic working conditions which include particle flow conditions,charging voltage and concentration.Some conclusions are shown as following: different sorts of particles are of different agglomer... |
