Fuzzy network based control system and method for harmful emissions from pesticide incinerators

Abstract

The invention discloses a system and method for controlling standardized discharging of noxious substances of a pesticide incinerator through a fuzzy network. The system comprises the incinerator, an intelligent instrument, a DCS system, a data port and an upper computer. The DCS system comprises a control station and a database, the intelligent instrument used for measuring easy-to-measure variables is connected with the DCS system, and the DCS system is connected with the upper computer through the data port. The upper computer carries out pre-processing and fuzzification on a training sample firstly to obtain a new input matrix, then a regression model of the new input matrix is built through an RBF neural network to obtain predicted output, and ultimately, defuzzification is carried out on the output of the RBF neural network to obtain output of the system. The upper computer further has the functions of model updating and result displaying. The system and method have the advantages of being capable of measuring COD on line, effectively monitoring whether the COD exceeds the standard and controlling discharging of the COD to be standardized, being resistant to noise, strong in self-learning capacity and high in calculation speed, and the like.

Description

technical field [0001] The invention relates to the field of pesticide production, in particular to a fuzzy-network pesticide incinerator harmful emission control system and method. 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 dealing with pesticide residues and waste residues....
