【Abstract】 The technical principle of high efficient evaporators of self-cleaning with twisted strips is that the cycle flowing energy of evaporating solutions is directly utilized to make the inserted twisted strips spin to continuously clean crystals or fouling.Based on the principle of crystallization dynamics,simulated cleaning experiments of hydrodynamics were conducted by using carbon steel tubes,through which saturated solutions Na 2SO 4 or KCLO 3 flowed while being cooled.Experimental results indicate that the cleaning ability of twisted strips’ motion can meet the self-cleaning requirement of evaporators and this new technique can not only realize continuous production of eveaporators for a much longer time but also raise production capacity and reduce much energy consumption.Therefore,it can be widely used in many industries such as sugar,salt,caustic soda,chemical,food and medicine.更多还原
