STUDY OF ELECTROSTATIC PRECIPITATOR FOR MECHANICAL SHAFT KILN IN CEMENT WORKS

Contraposing to the characteristics of the flue gas from the mechanical shaft kiln in cement works,the effects of the temperature of the flue gas and moisture content on the field voltampere character of an electrostatic precipitator are analyzed theoretically.A conductanc paint is used for the electrode plates in order to avoid their corrosions.Therefore the influence mechanism of the coatings on the field volt ampere characteristics and the discharge performance of the dust layer is also studied systematically.An electrostatic precipitator designed specially for treating the flue gas from the shaft kiln has a special field structure and cathodic suspension,which have good effectiveness of treating this sort of flue gas.
