Beschreibung
Zusammenfassung:	The invention relates to smoke ultra-low emission purification equipment of a coal-fired industrial boiler. The smoke ultra-low emission purification equipment of the coal-fired industrial boiler comprises SNCR denitrification equipment communicating with a boiler body, and a desulfurization and denitrification dust removal assembly communicating with a smoke outlet flue of the boiler. The sulfurization and denitrification dust removal assembly is connected with a purified air outlet. When the boiler is a medium-small coal-fired industrial boiler with unstable combustion and loads, the SNCR denitrification equipment is medium-temperature denitrification equipment, and the denitrification temperature is 500-800 DEG C. When the boiler is a medium-large coal-fired industrial boiler with stable combustion and loads, the SNCR denitrification equipment is high-temperature denitrification equipment, and the denitrification temperature is 800-1100 DEG C. The purification equipment can meet the ultra-low emission requ
