Detailed description of the invention
Defer to technique scheme, the highly effective reaction device for ozone denitrification process of the present utility model,
Including flue 1 and ozone injection equipment 2, in described flue 1, it is provided with ozone reaction platform
3, it is provided with multiple spoiler 3-1 in ozone reaction platform 3, ozone injection equipment 2 is arranged on described
The smoke inlet end of flue 1.
Flue gas is entered by the arrival end of flue 1, and the ozone that ozone injection equipment 2 ejects is by flue gas
The arrival end of pipeline 1 enters in ozone reaction platform 3, ozone under the barrier effect of spoiler 3-1,
Flue gas is formed flow-disturbing, effectively ensures ozone and flue gas full and uniform mixing within the extremely short time, carry
High ozone utilization rate and nitric oxide production efficiency, significantly shorten reaction required time, ensure
The high efficiency that ozone is out of stock.
While ozone and flue gas high efficient mixed, in order to ensure the flue gas smooth stream in flue 1
Logical, described spoiler 3-1 edge in described ozone reaction platform 3 sets with the vertical direction that flows to of ozone
Put, and adjacent spoiler 3-1 interlaced arrangement, form S type runner 3-2.
Ozone injection equipment 2 includes house steward 2-1, arranges multiple arm 2-2 below house steward 2-1, multiple
Arm 2-2 is spacedly distributed below house steward 2-1, and the axis direction of arm 2-2 is perpendicular to house steward
The axis direction of 2-1；Arm 2-2 is arranged on the inside of described flue 1 arrival end；Arm 2-2
Sidewall on have a slit-aperture type jet 2-3, slit-aperture type jet 2-3 along the axially arranged of arm 2-2
Ensure that the ozone ejected has preferable uniformity in the axial direction of arm 2-2.
