The invention provides a fuzzy control-based method and system for purifying waste incineration flue gas. The flue gas purification control method includes: receiving the detection input quantity sent by the detection device, and calculating the deviation between the detection input quantity and a given value and the change rate of the deviation as the input variable of fuzzy control; fuzzifying the input variable into fuzzy Input quantity, fuzzy reasoning and decision-making based on fuzzy input quantity to obtain fuzzy output quantity, and defuzzify the fuzzy output quantity into control output quantity; output the control output quantity to the corresponding parameter controller of the semi-dry flue gas treatment system to obtain the fuzzy output quantity Controls the amount of the corresponding parameter. Among them, the detection input includes the flow of sulfur dioxide and hydrogen chloride at the chimney outlet of the waste incinerator, and the control output corresponding to the flow of sulfur dioxide and hydrogen chloride is the flow of lime slurry and the flow of activated carbon, respectively. The above-mentioned method and system can solve the situation of variable parameters, numerous variables, and strong coupling between variables in the flue gas purification control system.
Description
technical field [0001] The invention relates to flue gas treatment after incineration of garbage and other wastes, in particular to a method and system for purifying flue gas purification of garbage incineration based on fuzzy control. Background technique [0002] At present, the relatively mature process of waste incineration flue gas purification is semi-dry method + dry method + bag dust removal + activated carbon process. The key equipment for flue gas treatment includes: semi-dry method deacidification reaction tower, dust collector, SNCR, and fly ash collection. Among them, the control system of the semi-dry deacidification reaction tower is the core part of waste incineration flue gas purification. The control performance of key systems will directly affect the treatment effect of waste incineration flue gas purification system, and then affect environmental protection emission indicators. [0003] The flue gas purification system is a complex, multi-variable, long-d...
