The invention discloses a simplified SCR denitration system for a gas turbine and a waste heat boiler generator set. The simplified SCR denitration system comprises a urea solution preparation system,a urea solution conveying system, a urea solution feeding system and an SCR catalytic system, which are sequentially connected. The urea solution preparation system comprises a urea dissolution tankand a disturbance device installed at the bottom of the urea dissolution tank and connected to the urea dissolution tank. The urea solution conveying system comprises a urea solution storage tank, a plurality of urea solution supply pumps and a flow regulating device. The urea solution storage tank is respectively connected to the urea dissolution tank and the urea solution supply pumps. The ureasolution supply pumps are connected to the flow regulating device. The urea solution feeding system comprises a plurality of spray guns. The spray guns are arranged in a flue with flue gas at 350-650DEG C. The SCR catalytic system comprises a waste heat boiler and an SCR catalyst in the waste heat boiler. The SCR catalyst is arranged in the hearth of the waste heat boiler at 320-420 DEG C.
Description
technical field [0001] The invention relates to the field of SCR denitration systems, in particular to a simplified SCR denitration system for gas turbines and waste heat boiler generator sets. Background technique [0002] At present, the conventional SCR denitrification system includes urea solution preparation system, urea solution delivery system, urea pyrolysis system, urea solution dosing system, SCR reactor, soot blowing system, etc.; urea solution preparation system includes urea dosing, stirring The urea solution delivery system adopts the combination of pump and regulating valve; the urea pyrolysis system includes the urea urea solution dosing system and the urea pyrolysis furnace; To the SCR inlet, the flue gas is denitrified and then led back to the flue behind the furnace; the soot blowing system includes a sonic soot blower, etc.; so the process is lengthy and complicated, and the investment is large. [0003] Therefore, await further improvement. Contents o...
