Abstract: A smart fault monitoring method based on a high-order information-enhanced recurrent neural network, said method being used to carry out real-time monitoring of wastewater treatment process faults, and comprising two phases: offline training and online soft measurement. The offline phase first uses OICA to extract raw data into high-dimensional high-order information features, used for the effective processing of non-Gaussian properties of the data and determining the correlation between variables. Then training of the extracted features is carried out by means of a DRNN. In the online phase, the data are mapped directly into new high-order feature components and are classified and discriminated by the DRNN that was trained offline. If the results are fault-free, then a monitoring model composed only of OICA is used to carry out unsupervised monitoring. If a fault has still not been detected at this point, the process is determined to be fault-free, and if a fault occurs, then the process is determined to be faulty and the fault information is entered into the network training data and training is carried out, thereby continuously improving the monitoring precision of the DRNN.

Abstract: The present invention provides an ethoxy methylene malononitrile continuous synthesis method. The method comprises the following steps: malononitrile, triethyl orthoformate, and acetic anhydride are continuously introduced into continuous reaction equipment for a substitution reaction to obtain ethoxy methylene malononitrile, and during the process of the substitution reaction, the generated ethoxy methylene malononitrile is continuously discharged, wherein the molar ratio of malononitrile, triethyl orthoformate, and acetic anhydride is 1:(0.9-6.0):(2.0-6.0). In the present invention, by using the continuous reaction equipment, the amount of materials participating in the reaction per unit time is greatly reduced, and therefore, a high-temperature hazardous area is reduced, and the safety risk is greatly reduced. Moreover, a continuous reactor can instantly heat raw materials to a reaction temperature, thereby avoiding the decomposition of the raw materials caused by a long-term temperature rising process, and thus the yield is significantly improved. Moreover, in the reaction process of the present invention, a class II toxic solvent such as methylbenzene is not required.
