Description

technical field [0001] The invention relates to an optimization scheduling system, in particular to an energy system comprehensive optimization scheduling system of a pulp and paper making enterprise. Background technique [0002] The paper industry is an important basic raw material industry that is closely related to the development of the national economy and social undertakings. 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 average water reuse rate of my country's paper industry is only 46%, and the average water consumption per ton of paper is as high as 100m 3 Above (world advanced level is only 10-20m 3 ), the fresh water consumption per 10,000 yuan of industrial output value is as high as 188 cubic meters. The high energy consumption of the papermaking industry not only leads to lo...

Problems solved by technology

However, at present, my country needs to strengthen the research, development and application of energy optimization technology and energy-saving technology integration (including unit equipment energy-saving technology and system energy-saving technology integration) in the paper industry. The energy scheduling method of industrial production makes the automatic degree of energy scheduling of pulp and paper production seriously lag behind

In addition, due to the inability to obtain comprehensive production data, the existing energy dispatchers in the pulp and paper industry can only conduct dispatching based on a small amount of information and their own experience. Such an approach is neither scientific nor accurate, resulting in serious waste of energy consumption in industrial production , increasing the emission of pollutants from the enterprise

Many scientific research institutions have begun to focus on research in this area. The sixth issue of 2006 and the second issue of 2007 "Paper Science and Technology" published the titles "Process Energy Synthesis Technology and Its Application in Energy System Optimization of Paper Industry". Application (I) - Theoretical Basis of Process Energy Synthesis Model", "Process Energy Synthesis Technology and Its Application Research in Paper Industry Energy System Optimization (II) - Application of Process Energy Synthesis Method and Model in Paper Industry Energy System " article, proposed to apply the "three links" energy flow model library to the energy optimization of papermaking enterprises, and achieved preliminary results, but it has not yet adapted to the wide application in production
