Abstract
The invention relates to a system for controlling comprehensive parameters in a sintering machine flue gas hood. The system comprises the flue gas hood, an adjusting valve, a main pipeline, a circulating fan air door and a control system. The system is characterized in that the control system comprises an oxygen meter, a thermometer, a pressure gauge I, a pressure gauge II, a logic controller andcomputer software, wherein the oxygen meter, the thermometer and the pressure gauge I are arranged below the adjusting valve, and the pressure gauge II is arranged in the main pipeline; the logic controller is electrically connected with the oxygen meter, the thermometer, the pressure gauge I, the pressure gauge II, the adjusting valve and the circulating fan air door, and the computer software iselectrically connected with the logic controller; and the computer software comprises a comprehensive parameter analysis unit, an air inlet main pipeline pressure adjusting unit, an oxygen content adjusting unit, a pressure adjusting unit and a temperature adjusting unit. The system has the advantages that through the adjustment and control of the circulating fan air door and the adjusting valve,the PLC multi-point detection and comprehensive analysis algorithm is combined, so that the coordinated control of the comprehensive parameters is realized, the quality of sintered ore is improved, and energy conservation, emission reduction and consumption reduction are achieved.
Description
technical field [0001] The invention relates to the technical field of industrial computer real-time control, in particular to a comprehensive parameter control system and method in a fume hood of a sintering machine. Background technique [0002] Traditional sintering production has the characteristics of large amount of waste gas, serious pollution load, and many types of pollutants, and sintering flue gas circulation technology can solve this problem well. Flue gas circulation is a process in which the flue gas emitted during the sintering process is recycled and reused, and the amount of recycled flue gas accounts for 20% to 30% of the total emission. This technology not only reduces the total flue gas emission and heat loss of sintering production, but also causes secondary chemical reactions between nitrogen oxides and sulfur oxides during the flue gas circulation process, converting some harmful substances into harmless substances, Reduced emissions of harmful substa...
