Abstract
In order to reduce energy consumption in sugar production and respond to the demand for carbon reduction,this study explores the application effect of thermal vapor recompression technology(TVR)in a three effect plate evaporation system.The difference in steam consumption between traditional triple effect evaporation and TVR+triple effect evaporation systems was compared and analyzed through system theory calculations and actual operation verification.The results showed that TVR technology significantly improved the first effect evaporation efficiency by injecting secondary steam and mixing it with high-pressure power steam,theoretically reducing the steam consumption per ton of water from 0.516 t/h in traditional systems to 0.391 t/h.In actual operation,the average steam consumption per ton of water in the TVR+system has been further reduced to 0.381 t/h,saving approximately 200000 yuan in steam costs annually.However,this technology relies heavily on the stability of high-pressure steam supply and has issues such as limited injection capacity and operational noise.In summary,TVR technology can effectively achieve energy conservation and consumption reduction in sugar refining and evaporation systems,but it is necessary to optimize steam supply design,improve injector performance,and take noise reduction measures to enhance applicability.关键词
