Robust data coordination method, device and storage medium for alumina production evaporation process

Abstract

The invention relates to a robust data coordination method, a device and a storage medium for an alumina production evaporation process. The method includes acquiring data of each measurement variablein the process of alumina production evaporation, and establishing a hierarchical robust data coordination model based on a robust estimation function of the data of each measurement variable; processing the data of each measurement variable based on the hierarchical robust data coordination model to obtain a first coordination result. The first coordination result obtained by the method is accurate when there is significant error and the magnitude is uncertain. The apparatus includes a display, a processor, and a computer program stored on a memory and executable on the processor, the processor implementing the steps of the method when executing the computer program. The storage medium stores thereon a computer program which, when executed by a processor, implements the steps of the method described above.

Description

technical field [0001] The invention relates to the field of data processing and modeling of the evaporation process of alumina production, in particular to a robust data coordination method, device and storage medium of the evaporation process of alumina production. Background technique [0002] As one of the key processes in the alumina production process, the evaporation process plays an important role in recycling useful resources and reducing the discharge of waste lye. This process evaporates excess water in the seed liquor and wash filtrate by heating steam, providing a high concentration circulating mother liquor for the dissolution process. In the actual evaporation process of alumina production, the process measurement data is inevitably disturbed by errors, which makes the measurement data deviate from the true value, and does not meet the boundary constraints of material mass balance, heat balance relationship and process parameters. In addition, limited by dete...
