Abstract

The invention discloses a temperature control method of a rapid non-overshooting heating jacket type heating reaction kettle. The method comprises the steps that a temperature control system is composed of an electronic heating pipe based on pulse width modulation power, a programmable logic controller (PLC) and a monitoring computer; an open loop step response test is carried out in a full-power heating mode, and a heating response transfer function model of the jacket type heating reaction kettle is built according to the test detection temperature data; the forms of a robust closed-loop control system and a controller are designed based on a response model; finally, controller parameters are set to be in an appropriate range according to the actual power of a heating device and working condition constraint conditions of the reaction kettle. By the adoption of the temperature control method, the heating speed of a solution of the jacket type reaction kettle can be quantitatively adjusted, it is ensured that a heating target value is achieved in a non-overshooting mode, and therefore a convenient and reliable automatic control method is provided for heating adjustment of chemical polymerization, distillation separation, biological fermentation and other technologies.

Description

technical field [0001] The invention belongs to the technical field of industrial process control, and relates to a rapid temperature rise control method for an industrial jacketed heating reaction kettle, in particular to a temperature control method for rapid and non-overshoot heating jacketed heating reaction kettle. Background technique [0002] Jacketed heating reactors used for chemical polymerization, distillation separation, and biological fermentation generally use temperature control to regulate the production process. For many polymerization and distillation separation processes, the polymerization reaction and product separation are mainly realized by temperature rise operation. Since the temperature rise rate and stability directly determine the product quality and production efficiency, temperature rise control is the core technology of the production process. In actual engineering practice, due to the inconsistency in the volume of the reactor and the large di...
