Purifying device for flue gas from waste incineration

The invention relates to a flue gas treatment system, and particularly relates to a purifying device for flue gas from waste incineration. An active carbon feeding port is arranged in an air pipeline between an air filter and a blower of the flue gas purifying device for waste incineration provided by the invention, active carbon is fed into the air pipeline by an active carbon quantitative feeding system through the active carbon feeding port to be mixed with air, then is uniformly mixed with air by the blower, and finally is delivered to a flue gas inlet flue, so that the mixed distribution uniformity of active carbon in flue gas is improved, and the adsorption effect of active carbon to dioxin and heavy metals is improved. In addition, the blower also plays the role of providing power, so that far distance delivery of active carbon is achieved, the pipeline plugging is avoided, and the use is simple and convenient.
