Problems solved by technology
During the actual project operation, the operation status of the front-end smelting process (such as start, stop, normal, change in feeding amount, etc.) often changes, resulting in frequent changes in the amount of flue gas, steam, and water in the flue, often due to waste heat boiler control Insufficient amount of information in the system causes automatic control disorder
In order to ensure the safe operation of the overall project, manual control is usually used instead of automatic control at this time, which requires more labor and lower utilization rate of automation

The invention provides an intelligent waste heat boiler optimizing control system. The intelligent waste heat boiler optimizing control system comprises a waste heat boiler and a waste heat boiler controller, wherein the waste heat boiler comprises a waste heat boiler drum; and whether the waste heat boiler is in a manual control mode or not and whether the running state of the waste heat boiler is normal or not are judged, according to the judged result, detecting data of instruments around the waste heat boiler are stored, and the automatic control mode of the waste heat boiler is optimized.The intelligent waste heat boiler optimizing control system is based on smelting big data analysis, a large number of real-time detecting data can be stored, control information well running under each class of working condition is recorded, and the control information is taken as a set value of an automatic control loop under the class of working condition, so that the automatic control mode isconstantly optimized, the self-adaptive ability of the waste heat boiler control system is improved, it is ensured that the work of the waste heat boiler control system is always in the stable state,and thus the manual input cost is reduced.
Description
technical field [0001] The invention relates to the technical field of metallurgical manufacturing and design, in particular to an intelligent waste heat boiler optimization control system based on smelting big data analysis. Background technique [0002] As a kind of energy saving and emission reduction equipment, the waste heat boiler is an indispensable key link in the smelting process. Its main function is to cool down the flue gas generated by the furnace body in the smelting process, and at the same time use the heat released in the flue gas cooling process to generate Steam, which is then used in other production processes. The stability of waste heat boiler operation is directly related to the operating rate of the smelting process and the reliable operation of subsequent related systems. [0003] In the existing smelting industry, the data signal in the waste heat boiler has been collected and controlled, which involves a large amount of information, and the more i...
