The utility model relates to flue gases purification field, be specifically related to the equal mixing device of a kind of gas, comprise at least one group of static mixer be arranged in flue, often organize static mixer to be made up of 4 mixer units, each mixer unit is made up of the mixed plate blade that two intersect, and mixed plate blade becomes 30 ° ~ 60 ° angles with flue gas flow direction, the mixed plate blade of described mixer unit is fixed in flue by support bar.Flue gas is through often organizing static mixer, except the local eddy currents that each mixed plate blade is formed, the adjacent 4 pieces of mixed plate blades in center are then formed counterclockwise (or clockwise) eddy flow whirlpool, 4 pieces of peripheral mixed plate blades then produce rightabout eddy flow whirlpool, thus on flue gas flow direction, form the contrary double vortex flow in direction; The mixing of inverse double-rotation eddy current is strong, enhances mixed process, ammonia is uniformly distributed, shorten simultaneously and reach ammonia homogenising target required separation distance, improve denitration efficiency; The pressure drop caused is less, and energy utilization efficiency is high. |
