The swirl flow effect was introduced in the spouting bed to change the velocity and volume distribution of the gas phase in different directions, strengthen the radial disturbance, increase the contact area, and optimize the mass transfer, heat transfer, and transmission efficiency of the two-phase flow in the spouted bed. The drying efficiencies of a conventional spouted bed and a spouted bed with an integral swirling blade nozzle (ISBN) under various particle diameters, filling weights, and drying temperatures were experimentally studied. It was found that under the same conditions, the drying activation energy of the ISBN increased, the drying time was shortened, the drying rate increased, the moisture diffusion in the bed accelerated, and the unit energy consumption decreased. When T = 70 °C, d = 1.5 mm, and m = 66 g, the ISBN drying efficiency was the highest.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
