【摘要】：針對(duì)稀土萃取分離過(guò)程工藝復(fù)雜/難以對(duì)其建立精確的過(guò)程控制模型,提出了稀土萃取過(guò)程遺傳算法優(yōu)化BP神經(jīng)網(wǎng)絡(luò)建模方法.根據(jù)現(xiàn)場(chǎng)工藝參數(shù),確定稀土萃取過(guò)程級(jí)數(shù)和各進(jìn)料設(shè)定流量;運(yùn)用串級(jí)萃取理論對(duì)稀土萃取過(guò)程產(chǎn)生各級(jí)組分含量數(shù)據(jù)分析;應(yīng)用Matlab7.10數(shù)學(xué)軟件進(jìn)行分析計(jì)算,為確保2端出口產(chǎn)品最終達(dá)到所需純度對(duì)過(guò)程進(jìn)行研究分析,并以Ce Pr/Nd萃取過(guò)程為例進(jìn)行建模研究,對(duì)實(shí)際生產(chǎn)過(guò)程工藝操作控制具有一定的借鑒意義.
[Abstract]:In view of the complex/ difficult process control model of the process of the extraction and separation of the rare earth, a genetic algorithm for the extraction of rare earth is proposed to optimize the BP neural network modeling method. according to the on-site process parameters, determining the series of the rare-earth extraction process and the flow of each feed; using the cascade extraction theory to analyze the content data of the components at various levels in the rare-earth extraction process; and using the Matlab7.0 mathematical software to carry out the analysis and calculation, In ord to ensure that that final product of the 2-terminal outlet achieve the required purity, the process is study and analyzed, and the model research is carried out by taking the Ce Pr/ Nd extraction process as an example, which has certain reference significance to the practical operation control of the practical production process.
