The present invention relates to an ammonia mixing device of the exhaust gas duct,n n n In the apparatus for mixing the ammonia and the exhaust gas in the exhaust gas duct (1) to increase the removal efficiency of the nitrogen oxide contained in the exhaust gas, cross-supports provided on the inner wall of the exhaust duct (1) Since four discs 3 are provided in (4) inclined with respect to the flow direction of the exhaust gas,n n n There is an advantage that the mixing effect of ammonia gas and exhaust gas is greatly increased,n n n In addition, when the total area and the inclination angle of the disk are the same, the four divided disks reduce the pressure loss by 70 to 80% compared to the one disk, and the length of the mixing device in the flow direction is also reduced, which greatly reduces the overall duct length. There is also an advantage that can be. |
