Description
Technical Field
The invention belongs to the technical field of analysis, evaluation and optimization of energy consumption and carbon emission in a blast furnace ironmaking process, and particularly relates to a method and a system for analyzing the energy consumption and the carbon emission of a blast furnace with industrial big data.
Background
The steel industry is an important pillar type industry for national economy development, and is also a large household with high energy consumption and high emission. According to data statistics, the energy consumption of the steel industry accounts for 15% of the total national energy consumption, and the carbon emission accounts for 13% -15% of the total national carbon emission. The energy-saving low-carbon transformation task of the steel industry is severe. The blast furnace ironmaking process is the most main component part in the long-flow production of steel, consumes a large amount of fossil energy and discharges a large amount of CO2 along with the production process, and according to data, the energy consumption of the blast furnace ironmaking process accounts for about 47% of the energy consumption of the whole-flow production of steel, and the CO2 discharge accounts for about 40% of the total-plant discharge, so that the energy-saving and emission-reducing spearhead in the steel industry is used for reducing the energy consumption and CO2 discharge of the blast furnace ironmaking process.
At present, the calculation method of the energy consumption and the carbon emission of the blast furnace process is mature, the statistical range of the energy consumption of the blast furnace process is defined in the energy consumption limit of the unit product of the crude steel production main process (GB 21256-2013) implemented in the 10 th month 1 of 2014 in the calculation of the energy consumption of the blast furnace ironmaking process, the content and the method of the calculation of the energy consumption of the blast furnace process are specified, and various energy refraction standard coal coefficient recommended values are provided for calculating the energy consumption of the blast furnace. Aiming at the calculation method of carbon emission in the steel industry, a plurality of versions are formed in China, and the method with the latest popularization time and the most extensive application at present is the part 5 of the requirements for accounting and reporting of greenhouse gas emission: iron and steel manufacturing enterprises (GB/T32151.5-2015), wherein accounting boundaries, accounting contents and specific methods in the iron and steel production process are specified, carbon emission calculation modes for the whole flow and each production process of the iron and steel industry are elaborated, carbon emission report templates and recommended emission factors of some common fossil fuels and production process substances are provided, and standards are provided for calculating carbon emissions for iron and steel production.
At present, the analysis method for exploring the energy consumption and the carbon emission of the blast furnace has certain implementation difficulty and limitation, for example, the mechanism in the production of the blast furnace is unclear, a large number of uncertain chemical reaction processes exist, and when the condition of the blast furnace fluctuates, the analysis result based on the mechanism of the blast furnace is poorer in accordance with the actual condition. It is difficult to directly quantify the degree of influence of each production parameter mechanically for blast furnace energy consumption and carbon emission analysis.
At present, the analysis of energy consumption and carbon emission of the blast furnace mainly focuses on input-output conditions in production index calculation, and influences on other production parameters of the blast furnace are found to be insufficient. The production of the blast furnace can be regarded as a 'black box model', the production parameters are numerous and disordered, in the analysis and judgment of the energy consumption and the carbon emission of the blast furnace, the influence degree of each production factor on the energy consumption and the carbon emission of the blast furnace is difficult to be quantitatively analyzed directly from the mechanism side, and the main factors influencing the energy consumption and the carbon emission of the blast furnace are difficult to be directly grasped on the premise of too many influence factors. Along with the daily production of the blast furnace, the energy consumption and carbon emission influencing factors can also change substantially along with the production condition, and how to accurately, timely and rapidly analyze the energy consumption and the carbon emission of the blast furnace becomes the main development direction of energy conservation and carbon reduction of the blast furnace nowadays.
