【摘要】 本文用新理论和以往典型理论及实验模型中的实测值进行了比较,发现不同的局部阻力系数(?)对收集效率影响很大,(?)大,收集效率低;(?)小,收集效率高,新理论计算所得效率值和实测效率值很接近.通过讨论得出:新理论是一个包含静电力、重力、紊流混合及电风综合影响的静电收集通用理论模型,Deutsch公式只是一种简化的特殊形式。同时粒子有效驱进速度随风速变化有一最大值出现在本文得以证实。更多还原

【Abstract】 This paper compares the new theory of elctrostatic precipitator with typical established theories and the efficiency values obtained from model precipitators.It is found that local resistance coefficient ξ will greatly affect the collection efficiency of ESP.If ξ is large,collection efficiency will be low.Conversely if ξ is small,collection efficiency will be high.And theefficiency values worked out by the new theory are close to those actually found in the model precipitator. Through discussion it is concluded that the new theory is such a general theoretical model as to iuclude manyfold effects of electrostatic force, gravity, turbulent mixing aud electric wind whilst Deutschian formula is a simplified form. Also, it is verified that particle effective migration velocity varies with gas velocity and has a maximum value.更多还原
