Abstract: There are many kinds of common problems in the wet desulphurization project of cement engineering. For example, limited transformation space, short construction period, complex pipeline, procurement contracts and short procurement cycle, many construction teams at the same time, large fluctuations in flue gas sulfur content. Tianjin Cement Institute independently developed a set of perfect wet desulfurization project construction technology and new management model. The project adopts Visual 3D design to optimize construction scheme and advanced 3D flow field simulation technology to improve desulfurization efficiency. During project management, managers use the BIM platform to control the whole process of project equipment procurement, transportation, installation and construction. By using the intelligent desulfurization control system and the debugging database service, the designer realized the whole process of the desulfurization system construction can be controlled. After the application of Huaikan South Project, the desulphurization system runs stably. The SO2 emission concentration of kiln tail is better than the national standard, and the construction time is only 90 days. Huaikan project is one of the shortest construction time of wet FGD projects in cement engineering in China.
