Intelligent control system for chemical product recovery process

Abstract

The invention discloses an intelligent control system for a chemical product recovery process. The intelligent control system comprises a chemical product recovery process visualization module, a set value computation module, a data acquisition and output module, a coordinative optimization module, and system hardware; the data acquisition and output module transfers a data result to the chemical product recovery process visualization module; the chemical product recovery process visualization module feeds field equipment parameters and process parameters back to the data acquisition and output module; the data acquisition and output module receives an operation parameter set value of the set value computation module and feeds procedure parameters back to the set value computation module; the set value computation module obtains a state parameter optimization set value from the coordinative optimization module and transfers real-time and historical data to the coordinative optimization module; and the coordinative optimization module is used for realizing coordinative optimization of coal gas purification and recovery processes. The intelligent control system can achieve a synergistic effect integrating visualized presentation, data management, coordinative optimization, data mining and energy conservation, and realize benefit maximization under the premise of ensuring safety in production.

Description

technical field [0001] The invention belongs to the technical field of coking chemical production recovery, in particular to an intelligent control system for the chemical production recovery process. Background technique [0002] Chemical recovery is a typical complex process industrial process, which has many influencing factors, large process fluctuations, accompanied by a large number of physical and chemical reactions and heat exchanges, and many variables, constraints, and objectives. The existing recycling process loop control is traditional control, which lacks feed-forward analysis of chemical production recovery process, lack of analysis of production history data, lack of mining of "production index-state parameter-operation parameter" relationship rules, and lack of comprehensive production target Considering the coordination and optimization of the system, manual adjustments are frequent, feedback lags behind, the overall control effect is not ideal, and it is d...
