A discrete manufacturing pipeline quality prediction method based on mechanism and data joint driving belongs to the field of intelligent manufacturing and industrial artificial intelligence, and the method comprises the following steps: first, data acquisition and preprocessing under the industrial scene of the discrete manufacturing pipeline; second, state space deduction and single variable nonlinear analysis of the sparse time sequence characteristics of the discrete manufacturing pipeline; third, mechanism joint training and real-time closed-loop intervention of the discrete manufacturing pipeline quality prediction model. The present application significantly improves the physical consistency of the discrete manufacturing pipeline quality prediction, realizes continuous inference of the hidden state under irregular sampling gaps, and enhances the safety decision-making ability and engineering application value of the automatic control of the discrete manufacturing pipeline.

The utility model discloses a kind of hydrogen purification devices, it includes 2 or more parallel hydrogen purification units, raw material main pipeline, purified hydrogen pipeline and relaxation separation tail gas pipeline, the hydrogen purification unit includes metal hollow fiber membrane assembly, heating component, the upper flange with gas outlet for discharging purified hydrogen, the intermediate flange with heat exchange jacket, and the shell with lower flange, the upper flange with gas outlet, the intermediate flange with heat exchange jacket and the shell with lower flange are connected airtight by nut, the shell with lower flange is located in the heating component. By adopting the hydrogen purification device of the utility model, crude hydrogen raw gas is first passed through heat exchange jacket before being purified using metal hollow fiber membrane assembly, heat exchange is carried out using heat exchange jacket, preheating of raw gas can be achieved, energy efficiency is improved, while helping to maintain system thermal balance, reducing equipment depreciation and operating risk caused by temperature fluctuation, enhancing the safety of the device.
