【Abstract】 The structural principle of the self-cleaning crystal fouling technolo gy for evaporators with twist-ed strips is that the twisted strips c an be driven to rotate by directly uti lizing the flowing energy of the evap orating solution in each heat transfer tube,which circulates through evaporato rs.According to the crystallizing d ynam-ics,the stimulated experiments of f luid dynamics were conducted,in whi ch the heat transfer tubes are carbon steel(25mm ×2.5mm ×1820mm)and the crystal of fouling on the tubes wall is from the supersaturating so lution of Na 2 SO 4 or KClO 3 .The Experimental results indicate that the new self -cleaning technolo gy with such twisted strips can meet the evaporators requirements for general production and the purpose of continuous productio n of long time can be reached.Furthermore,the technology has remarkable eco nomic advantages such as low equip-ment costs.It can be widely used in ma ny industries such as sugar,salt,ca ustic soda,chemical,food and medicine.更多还原
