【Abstract】 The energy consumption of different areas in a SMⅢ airlift reactor was investigated,using Newtonian and non-Newtonian experimental systems.The density of the experimental systems ramges from 1 000 to 1 800 kg·m^-3,the viscosity ranges from 0.000 1 to 0.27 Pa·s,and the gas flow rate ranges from 2 to 6 m³·h^-1.The energy consumption of different areas in the reactor was analyzed theoretically and calculated using experimental data,the character of the reactor was also evaluated on the basis of the energy consumption dissipation.更多还原
