| Abstract: | In the polymethyl methacrylate spouting bed with rectangular sections, four type of diameter spherical glass balls separated by narrow sieve are used, and normal temperature water adopted as spouting and auxiliary liquid. Systematically study the minimum spouting velocity of the spouted bed with a draft tube, obtain experienced minimum spouting velocity formula, and provide reference for design and operation based on considering geometric size of the bed, operating parameters and physical properties of the ... |
