Embodiment 1

[0049] The parallel irreversible reactions occurring in the batch reactor include: A→B and A→C. The reaction rate constant is a function of the temperature T(t), respectively

[0050] k 1 ( t ) = k 10 e - E 1 / R · T ( t )

[0051] k 2 ( t ) = k 20 e - E 2 / R · T ( t ) ...

Abstract

The invention discloses a batch reactor control system based on accurate punishment optimization. The batch reactor control system is formed by a batch reactor body, a temperature sensor at the end of the batch reactor body, an analog-digital converter, a field bus network, a DCS, a master-control room temperature and product concentration status displayer, a digital-analog converter at the end of a temperature control valve and the temperature control valve. After the duration time of the production process, the initial concentration state of materials in the reactor body and target products with concentration required to be improved are appointed by a control room engineer, the internal accurate punishment optimization method is implemented by the DCS, temperature control strategies which enable the concentration of the target products to be maximum are calculated and converted into opening instructions of the temperature control valve, the opening instructions are transmitted to the digital-analog converter at the end of the temperature control valve through the field bus network, and the temperature control valve executes corresponding motions. The temperature sensor at the end of the batch reactor body collects the temperature of the batch reactor body in real time, and therefore the control room engineer can master the production process at any time. The batch reactor control system enables the concentration of the target products to be maximum and achieves the aims of digging potential and improving efficiency.

Description

technical field [0001] The invention relates to the field of reactor control, and mainly relates to a batch reactor control system based on precise penalty optimization. It can automatically control the temperature of the reactor to increase the concentration of the target product. Background technique [0002] Batch reactor, also known as batch reactor, is widely used in petrochemical, fine chemical, pesticide and other industrial production. [0003] For a batch reactor with a fixed volume, when the material parameters such as raw material ratio and concentration are determined, under the condition of sufficient stirring, the key factor affecting the product output is the reaction temperature. Since the production process requirements of different products are different, it is of great significance to automatically control the optimal temperature of the batch reactor according to the production process requirements. [0004] At present, optimal control theory and corresp...
