The utility model discloses originally, provide a be applied to high cloud of dust gas SCR denitrification facility of cement kiln, including entry flue, ammonia injection grid, connection flue, the guide plate that flow equalizes, rectification grid, reactor casing, catalysis layer, combination soot blower, exhaust pass. Entry flue, connection flue, reactor casing, exhaust pass connect gradually along the flue gas trend, and ammonia injection grid sets up on the entry flue, and flow equalize guide plate and rectification grid are all placed in the connection flue, and the rectification grid is below the guide plate that flow equalizes, and the catalysis stratification is united the soot blower and is lain in the corresponding position of reactor casing in the reactor casing. The utility model discloses can guarantee denitration efficiency under high cloud of dust gas characteristic, reduce ammonia and escape to prevent the jam of catalysis layer. |
