Self-adaptive pesticide waste liquid incinerator harmful emission control system and method

Abstract

The invention discloses a system and method for controlling emission of noxious substances of a pesticide waste liquid incinerator to reach standards in a self-adaptation mode. The system comprises the incinerator, an intelligent instrument, a DCS, a data interface and an upper computer. The DCS comprises a control station and a database. The intelligent instrument used for measuring easily-measured variables is connected with the DCS. The DCS is connected with the upper computer through the data interface. The upper computer conducts standardized preprocessing on a training sample. A fuzzy neural network is adopted to establish a regression model, optimum optimization is carried out on linear parameters in the fuzzy neural network by introducing a support vector machine, the problem of parameter setting of the fuzzy neural network is solved, and meanwhile self-adaptation adjustment is carried out on the structure of the whole fuzzy neural network according to changes of the training sample. The upper computer further has the model updating function and the result displaying function. The system and method have the advantages of being capable of measuring COD in an online mode, effectively monitoring whether the COD exceeds the standards or not, controlling the emission of the COD to reach the standards, being strong in anti-noise capacity, optimizing parameters in an online mode, adjusting the structure of the system in the self-adaptation mode and the like.

Description

technical field [0001] The invention relates to the field of pesticide production, in particular to an adaptive control system and method for controlling the discharge of harmful substances from a pesticide waste liquid incinerator. Background technique [0002] my country is a big country in the production and use of pesticides. There are about 4,100 pesticide manufacturers, of which more than 500 are active pharmaceutical manufacturers. Statistics from the Ministry of Agriculture show that the total output of pesticides from January to November 2008 reached 1.711 million tons. The irrationality of the structure of pesticide varieties in my country has made environmental governance more difficult. According to incomplete statistics, the national pesticide industry discharges about 1.5 billion tons of wastewater every year. Among them, only 1% of the processed ones have reached the standard. Incineration is currently the most effective, thorough and widely used method for ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the shortcomings of the existing incinerator process COD that cannot be measured online and COD seriously exceeds the standard, the present invention provides an adaptive control system and method for controlling the discharge of harmful substances in the pesticide waste liquid incinerator, which has online measurement of COD and effective monitoring of COD. Whether it exceeds the standard, control COD emission to meet the standard, strong anti-noise ability, online optimization parameters, self-adaptive adjustment of system structure, etc.
