静电除尘器在磷石膏制硫酸联产水泥工程中的应用

Application of Electrostatic Precitator in Production of Sulfuric Acid Integrated with Cement from Phosphogypsum

本文阐述了磷石膏烘干脱水后,粉状半水石膏的收集、磷石膏煅烧窑气净化除尘均应选择静电除尘器的必要性。根据电除尘器处理介质(烘干尾气与水泥窑气)的特性及操作条件,介绍了设计选型要考虑结露、构件腐蚀、绝缘爬电等问题,并提出相应改进的措施。

The paper introduces the electrotatic precipitators are se- lected and used for the collection of powdered hemihydrate phosph- ogypsum and dedust to clean kiln gas from phosphogypsum-calcined section, after drying the phosphogypsum. The propertics of media （cement kiln gas and tail gas ）, and the necessity , operation pa- rameters and selection of specifition of the electrostatic precipitater with dew point factors, corrosion of equipment, creepage , as well as the determination of insulator and elimination of thermal collapse are discussed.
