Abstract

The invention discloses a pesticide production waste liquid incinerator temperature optimization system and method of a support vector machine. According to the method, the support vector machine and a fuzzy system are combined, a plurality of output results of the support vector machine are subjected to fuzzification, and accordingly accurate furnace temperature control results are obtained. A training sample is subjected to standardization processing module processing and is used as input of a fuzzy system module; a furnace temperature predicted value and an operation variable value which enables the furnace temperature to be optimum are obtained in the fuzzy system module which is connected with a result displaying module, the results are transmitted to a DCS; a model updating model is used for collecting field intelligent instrument signals according to the set sampling time intervals. Accuracy control of the furnace temperature and on-line train sample data updating are achieved, and the phenomena that the furnace temperature is too high or too low are avoided.

Description

Technical field [0001] The present invention relates to the field of pesticide production waste liquid incineration, in particular, to a support vector machine-based pesticide production waste liquid incinerator furnace temperature optimization system and method. Background technique [0002] With the rapid development of the pesticide industry, the environmental pollution of emissions has attracted great attention from governments and corresponding environmental protection agencies. Researching and solving the standard discharge control and harmless minimization of pesticide organic waste liquid has not only become a difficult and hot spot for scientific research in various countries, but also a scientific proposition related to the urgent needs of the country for the sustainable development of society. [0003] The incineration method is currently the most effective, thorough, and most commonly used method for processing pesticide residues and waste residues. During the incinera...
