Design of an Automatic Cleaning Energy-Saving Technology for Manganese Sulfate Continuous Production Crystallizer
To deal with the high energy consumption of the batch-type single-effect evaporator for Manganese sulfate production,a vibrating-spiral fluidized automatic cleaning technology was developed for continuous crystallizer production.The proposed method is presented followed by validation through a heat transfer coefficient comparison experiment.The result has shown that the proposed method has strong capability of automatic cleaning of crystalline scale.When the flow velocity in tubes is 0.80 m/s and the heat transfer temperature difference is 17℃,the overall heat transfer coefficient can reach 90% of that of clean tubes without spiral-fluidization.Furthermore,it is ideal to keep the volumetric concentration of fluidization particles at 1% and the automatic cleaning capability is almost directly proportional to the flow velocity.The automatic-cleaning continuous-production crystallizer technology can effectively replace the atmospheric-pressure single-effect evaporator and reduce the energy consumption by 95%.Comparing to the three-effect evaporator,the proposed method can save energy up to 88%.
