Description

A kind of synthesis optimizing and scheduling method of energy system
Technical field
The present invention relates to a kind of Optimization Dispatching method, particularly a kind of synthesis optimizing and scheduling method of energy system of enterprises in pulp and paper industry.
Background technology
The papermaking industry is and national economy and social cause development important foundation starting material industry in close relations.According to statistics in 2004, the general big-and-middle-sized papermaking enterprise energy utilization rate of China has only 30%, the comprehensive energy consumption of slurry paper per ton in 2005 is up to 1.38 tons of standard coal equivalents (advanced international standard only is 0.5 ton of mark coal), and ten thousand yuan of output value comprehensive energy consumptions of paper industry are up to 2.5~3.0 tons of standard coal equivalents.China's paper industry ratio of water recycle on average has only 46%, and average ton paper water consumption is up to 100m 3More than (advanced international standard only is 10~20m 3), ten thousand yuan of fresh water consumptions of the output value of industry are up to 188 cubic metres.The high energy consumption of paper industry has not only caused the poor benefit of production run, and caused the serious environmental pollution, this shows, energy system complex optimum technology and integrated technology with the advanced person are optimized and transform traditional papermaking industry, being the important channel of improving papermaking enterprise economic benefit, environmental quality and reduction unit consumption of energy, also is the main flow direction and the hot fields of the energy-saving and cost-reducing technical progress of paper industry in the world.
The energy synthesis optimisation technique is used for process industry (iron and steel, petrochemical industry, oil refining etc.) reduction enterprise energy consumption, improves the business economic benefit at present, become the emphasis gordian technique that National Development and Reform Committee applies, and listed among country's ten big energy conservation project embodiments.But China is in urgent need of strengthening aspect the research of integrated (comprising that unit power-saving technology and systematic energy-saving technology are integrated) of energy-optimised technology of paper industry and power-saving technology, development and application at present, this mainly is often not understand the energy dispatching method that pulp and paper industry is produced owing to grasp the personnel of infotech, makes pulping and paper-making production energy dispatch automatic degree and seriously falls behind.In addition, owing to can't obtain comprehensive production data, the existing energy dispatcher of pulp and paper industry can only dispatch based on a spot of information and the experience of self, and such way neither science is also inaccurate, the commercial production energy consumption waste that causes is serious, has increased the discharging of enterprise pollution thing.Many scientific research institutions have begun to be conceived to the research of this respect, 2006 06 phases, " paper science and the technology " of 2007 02 phases discloses name respectively and has been called " process energy synthesis technology and application (I)---the theoretical foundation of process energy synthesis model in the paper industry energy system is optimized thereof ", the article of " process energy synthesis technology and applied research (II)---process energy synthesis method and the model application in the papermaking energy system in the paper industry energy system is optimized thereof ", proposed " three links " energy system optimization method is applied to the energy-optimised of papermaking enterprise, obtained preliminary achievement, but owing to lack integrated approach and means, also fail aborning widespread use.
Summary of the invention
The object of the present invention is to provide a kind ofly, improve pulping and paper-making and produce energy dispatching automation degree, reduce the synthesis optimizing and scheduling method of energy system of energy consumption waste closely in conjunction with the actual demand of pulping and paper-making production run.
