摘　　要：针对反应釜温度分程控制仍有±5℃波动,无法精准控温的问题,采用增加1个副回路,与原回路形成串联,实现串级分程控制的方法。实施后提升了温控的精度,反应釜温度可以稳定在(53±0.5)℃,达到了预期的目标。此方法自动化程度高,适用性强,可应用于很多类似的化工反应的温度控制。Aiming at the problem that the temperature split control of the reactor still has±5℃fluctuation and cannot be accurately controlled,a method of adding a secondary loop to form a series with the original loop to realize cascade split control is adopted.After the implementation,the accuracy of temperature control is improved,and the reactor temperature can be stabilized at(53±0.5)℃,which achieves the expected goal.This method has high degree of automation and strong applicability,and can be applied to the temperature control of many similar chemical reactions.
