Monitoring control system of paper-making machine drying part energy system and working method thereof

Abstract

The invention discloses a monitoring diagnosis system of a paper-making machine drying part energy system, comprising a data preprocessing and guiding module for storing a uniform format and a unit of acquired logistic data of a paper-making machine drying part into a relational database module, the relational database module for storing and converting data, an energy system diagnosis model database for diagnosing and analyzing the logistic data stored in a relational database, a human-computer interaction interface for calling and displaying a diagnosis report obtained by the energy system diagnosis model database, and an energy system optimization scheme knowledge base and an optimization algorithms library for carrying out optimum design on the drying part system according to the diagnosis result of the energy system diagnosis model database module. By adopting the system and the method, the energy-using circumstance of the paper-making machine drying part can be comprehensively monitored in real time and automatically controlled, and the energy can be saved by 3-7%.

Description

technical field [0001] The invention relates to an energy system monitoring and control system of a drying section of a paper machine and a working method thereof, in particular to an energy system monitoring and controlling system and a working method of the drying section of a fully enclosed paper machine with multiple drying cylinders. Background technique [0002] The paper industry is an important basic raw material industry closely related to the development of the national economy. According to statistics in 2004, the energy utilization rate of general large and medium-sized papermaking enterprises in my country is only 30%. The comprehensive energy consumption is as high as 2.5-3.0 tons of standard coal. The paper industry has become one of the key regulatory industries with high energy consumption and high pollution in my country. In papermaking equipment, the energy consumption of the drying section of the paper machine accounts for about 50% to 60% of the product...

AI Technical Summary

Problems solved by technology

At present, the monitoring of the energy of the drying section of the paper machine in the papermaking enterprise mainly focuses on the control and adjustment of the logistics parameters at certain points. The data measured by the distributed control system (DCS) and the data measured on site are not available due to various reasons. Effective integration and analysis, and the incompleteness of measurement data also leads to incomplete monitoring, not to mention the monitoring of the energy utilization rate of the drying section of the paper machine and the analysis and optimal control of energy-saving potential

The current paper machine control system cannot monitor and optimize the energy utilization and recovery level efficiency of the entire drying section
