Problems solved by technology

However, since the static model is based on certain assumptions, these assumptions may not be met in actual production; in addition, many parameters in the static model are constant or empirical values, making it more difficult to guarantee the accuracy of the model

Embodiment Construction

[0012] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] Firstly, the overall block diagram of the integrated optimization method for process parameters in the flash smelting process is given, as shown in figure 1 shown. According to the general block diagram given, the integrated optimization method is as follows: the integrated optimization method includes balance calculation, optimization sample library, matching algorithm, intelligent coordination and other units. First of all, balance calculation is carried out, that is, according to the current situation of the materials entering the furnace, the required air volume and oxygen volume are calculated by applying the principles of material balance and heat balance. Then compare the current incoming materials with the excellent samples in the optimized sample library, find out 20 excellent samples that best match the current incoming mater...

Abstract

The invention relates to an intelligent integrated optimization method based on pattern matching and balanced computation, more particularly to a method for optimizing the operation parameter of the copper flash smelting process. The invention takes the stability of flash smelting comprehensive working condition as an optimization target, respectively establishes a mechanism model based on the balanced computation and a pattern matching intelligent optimization model based on fuzzy C average clustering, and adopts an intelligent integrated method to coordinate the optimization results of the two models. The method can obtain the optimal operation parameter of the copper flash smelting process, namely, the optimal addition amount of hot blast and oxygen of a flash furnace reaction tower, thus providing theoretical foundation and scientific optimized instruction for the adjustment of the operation parameter, and reducing the unstable working condition caused by the fluctuation of the parameter.

Description

technical field [0001] The invention relates to a method for optimizing process parameters of complicated industrial processes, in particular to an optimization method for process parameters in the copper flash smelting process. Background technique [0002] Flash smelting is the most important copper smelting method in the world today. The dried copper concentrate and the materials returned from the subsequent process are sprayed from the top of the reaction tower into the high-temperature (1450-1550°C) reaction tower at a high speed (60-70m / s), and the sulfide is decomposed within 2-3s. Processes such as decomposition, oxidation and melting produce matte copper and slag. Matte grade, matte temperature and iron-silicon ratio in slag are three important quality indicators of flash smelting effect. Therefore, how to control the process parameters of the flash smelting process - the air volume of the reaction tower and the amount of oxygen enrichment, so that the three major...
