Orthogonal collocation optimization based batch reactor control system

Abstract

The invention discloses an orthogonal collocation optimization based batch reactor control system. The orthogonal collocation optimization based batch reactor control system comprises a batch reactor body, a temperature sensor at the end of the batch reactor body, an analog to digital converter, field bus networks, a DCS (distributed control system), a main control room temperature and product concentration state displayer, an analog to digital converter at the end of a temperature control valve and the temperature control valve. After an engineer in a control room specifies duration of a production process, initial concentration states of materials in the batch reactor body and a target product needing concentration increasing, the DCS executes an internal orthogonal collocation optimization method to compute a temperature control strategy enabling the concentration of the target product to be maximum, the temperature control strategy is converted into an opening instruction of the temperature control valve, and the opening instruction is sent to the analog to digital converter at the end of the temperature control valve through the field bus networks so as to enable the temperature control valve to act correspondingly according to a received control instruction. By the system, the concentration of the target product can be maximized, and potential tapping and efficiency improvement are realized.

Description

technical field [0001] The invention relates to the field of reactor control, and mainly relates to a batch reactor control system based on orthogonal configuration optimization. It can automatically control the temperature of the batch 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 the...
