The invention relates to a flue gas denitrification device, and particularly relates to a fully-automatic regulating SNCR (selective non-catalytic reduction) denitrification device. The SNCR denitrification device is optimized further based on an original SNCR denitrification technique. The SNCR denitrification device for the fully-automatic regulating comprises a reducing agent (urea solution) preparation and storage module, a conveying and circulation module, an on-line metering and diluting module, and a distributing and jetting module arranged on the boiler wall based on CFD (computational fluid dynamics) simulation computation. The SNCR denitrification device for the fully-automatic regulating is characterized in that particle urea is conveyed to the storage module after being prepared into a urea solution; the conveying and circulation module and the metering and diluting module are arranged between a urea storage tank and the jetting module; the urea solution is quantitatively distributed in the jettin
