Problems solved by technology

As the control of flue gas treatment and emission indicators becomes more and more stringent, production and operation personnel often increase the dosage of purification materials such as lime slurry, activated carbon, and ammonia water to the maximum in order to meet the flue gas emission standards, resulting in relatively large waste

Abstract

The invention provides a fuzzy control-based waste incineration flue gas purification control method and system. The flue gas purification control method comprises steps of receiving a detection input quantity sent by a detection device, calculating a deviation between the detection input quantity and a given value and the deviation change rate as an input variable of fuzzy control; performing fuzzification of the input variable into a fuzzy input quantity, performing fuzzy inference and decision based on the fuzzy input quantity to obtain a fuzzy output quantity, and performing defuzzification of the fuzzy output quantity into a control output quantity; and outputting the control output quantity to a corresponding parameter controller of a semi-dry process flue gas processing system to control the quantity of corresponding parameters. The detection input quantity comprises the sulfur dioxide flow quantity and the hydrogen chloride flow quantity at an outlet of a waste incinerator chimney, and control output quantities corresponding to the sulfur dioxide flow quantity and the hydrogen chloride flow quantity are the lime white flow quantity and the active carbon flow quantity respectively. The method and the system can solve conditions of changeable parameters, many variables and close 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...
