摘　　要：针对食品添加剂的生产工艺要求,开发设计了一种采用外部风冷的不均匀散热化学反应器。该反应器在总化学反应时长的前1min里散热量为总热量的60%,后4min的时间里散热量为总热量的40%。所开发设计的化学反应器为管式内置扰流子空冷式不均匀散热化学反应器,通过热力计算和结构优化数值模拟,结果表明所设计的化学反应器满足生产工艺要求。In response to the production process requirements of food additives,an uneven heat dissipation chemical reactor equipped with external air cooling was developed.The reactor dissipates 60%of the total heat in the first minute of the total chemical reaction times and the 40%heat dissipation of the total heat can be seen in the last 4 minutes.The chemical reactor developed and designed has a tubular built-in turbulator and features air-cooled uneven heat dissipation.The thermal calculation and structural optimization and simulation showed that this chemical reactor designed can meet the production process requirements.
