[Abstract]:In this paper, the drying characteristics of spherical calcium chloride dihydrate in a fluidized bed granulator are tested in a pilot scale, and the design calculation and type selection of a fluidized bed granulator for the production of spherical calcium chloride dihydrate on a large scale are carried out. Combined with the data of industrial production, the advanced and scientific of the pilot test and design is verified. Firstly, the feasibility of the project is studied, which provides the practical basis and foundation for the industrial production. The effects of injection rate, fluidization speed and material temperature on the drying and granulation characteristics of calcium chloride dihydrate are summarized. Secondly, the paper synthetically utilizes the principles of thermodynamics and fluid mechanics, through heat balance and material balance, for the large-scale of the project. Industrialization and continuous production provide theoretical support, and combining with practical experience in chemical production, a large-scale continuous spray fluidized bed granulating equipment suitable for spherical calcium chloride dihydrate is designed. Finally, the industrial production data are used. The correctness of the test and design is verified, and the key points of the system are compared with those of the foreign system, which ensures the advanced nature of the system in the aspect of energy saving and performance.
