Évaporateur tubulaire

USED SWENSON SINGLE-EFFECT CRYSTALLIZER WITH THERMORECOMPRESSION. DESIGNED TO EVAPORATE UP TO 5175#/HOUR OF WATER. FORCED CIRCULATION CRYSTALLIZER CONSISTS OF A HORIZONTAL HEATING ELEMENT, VAPOR BODY, AND CIRCULATION LOOP. FEED SOLUTION ENTERS CIRCULATING LOOP DOWN STREAM OF HEATING ELEMENT WHERE IT IS MIXED WITH HEATED CRYSTALLIZER SLURRY. AXIAL FLOW CIRCULATING PUMP CIRCULATES SLURRY FROM VAPOR BODY THROUGH 2-PASS HORIZONTAL HEATING ELEMENT AND BACK TO BODY THROUGH TANGENTIAL INLET. STEAM IS ADDED TO SHELL SIDE OF HEAT EXCHANGER WHICH TRANSFERS HEAT TO SLURRY. HEATER IS SUBMERGED TO PREVENT VAPOR FORMATION IN TUBES. CIRCULATING SYSTEM PROVIDES FOR AN ADEQUATE FLOW INSIDE TUBES TO MAINTAIN HIGH HEAT TRANSFER RATE. SUPERSATURATION IS CREATED IN BODY NEAR BOILING SURFACE WHERE VAPOR IS RELEASED.
