WIPO Patent Application WO/2011/090258
Kind Code:
A2
Abstract:
The present invention relates to a system for denitrifying exhaust gas capable of preventing blockages in a urea water inflow path and an injection nozzle, and to device for supplying urea water capable of preventing the coagulation of urea water. The system for denitrifying exhaust gas includes a urea water injection unit supplying urea water and air to a reaction chamber, and the urea water injection unit includes an air supply unit for supplying external air to an injection unit through an air inflow path; a urea water supply unit for supplying urea water to the injection unit through a urea water inflow path; a water supply unit for supplying water to the injection unit through a water inflow path connected to one side of the urea water inflow path; a flow control valve for selectively supplying water or urea water to the injection unit through the urea water inflow path; and said injection unit connected to the air supply unit and to the urea water supply unit for selectively feeding air, urea water, and water into the reaction chamber. Blockages in the urea water inflow path and the injection nozzle due to the continuous feeding of urea water and air into the reaction chamber can be prevented by supplying water to the injection nozzle and to the urea water inflow path.
