Abstract

The present invention relates to a method for determining the optimal parameters of the thermal oil spraying and heating process of the oil storage tank, which includes: determining the decision variable according to the factors that affect the thermal oil spraying and heating effect of the oil storage tank in the actual production process; obtaining different The measured data of the thermal oil spraying heating process in the experimental storage tank under the parameters, the field synergy angle, uniformity, heating efficiency and average heating rate are used as indicators to evaluate the heating effect, the weights of each indicator are determined, and the objective function is calculated; through Decision variable and objective function establish a support vector machine model; based on the support vector machine model, an initial population of size M is generated, and a genetic algorithm is used to optimize the objective function; the optimized variables are used as experimental parameters for indoor simulation experiments to obtain the corresponding objective function , the error with the result of the support vector machine exceeds a certain range, then repeat the iteration until the error is less than a certain range. The invention can find the optimal process parameters, which ensures the calculation accuracy to a great extent.

Description

Technical field: [0001] The invention relates to the field of process parameter optimization in the thermal oil spraying and heating process of an oil storage tank, and specifically relates to a method for determining optimal parameters for studying the thermal oil spraying and heating process of an oil storage tank. Background technique: [0002] In recent years, the thermal oil circulation method has been gradually put into use in large-scale oil depots because of its high heat transfer efficiency and the elimination of defects that affect the quality of oil products due to equipment failures. Taking Daqing Oilfield as an example, through renovation and new construction, crude oil, finished products Almost all oil tanks have adopted this heating method. [0003] In view of the significant advantages and prospects of further popularization and application of the thermal oil spraying heating process, the basic characteristics of the heating process, especially the distributi...
