Abstract
The invention discloses an ammonia spray mixer, which comprises a flue, circular channels and blades, wherein a plurality of circular channels are formed inside the channel; and a plurality of arc-shaped blades are arranged in the circular channels. Sprayed ammonia gas and fuel gas enter the circular channels of the ammonia spray mixer, flow intensively in a turbulent form under the action of the arc-shaped blades and are fully mixed with each other in a small-distance range, so that flue gas mixing distance is greatly reduced, and flue gas mixing effect is enhanced.
Description
Technical field
The present invention relates to a kind of spray ammonia blender of equipment for denitrifying flue gas.
Background technology
Existing spray ammonia blender is that the rectangular paddle that some rows are interspersed is set in flue, makes flue gas reflect mixing in flue, and the mixing of flue gas distance is large in this structure, and mixed effect is undesirable.
Summary of the invention
Technical problem to be solved by this invention is: a kind of spray ammonia blender that improves the mixed effect of flue gas and reduce to mix distance is provided.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: spray ammonia blender comprises: flue, and circular channel, blade is provided with several circular channels in the inside of flue, is provided with several arc shaped blades in circular channel.
Advantage of the present invention is: the ammonia that sprays into and flue gas enter the circular channel of this spray ammonia blender, under the effect of arc shaped blade, ammonia and flue gas aggravation turbulent flow fully mix in the scope of small distance, the mixing distance of flue gas is dwindled greatly, has improved simultaneously the mixed effect of flue gas.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the top view of Fig. 1.
Among Fig. 1 to Fig. 2: 1, flue, 2, circular channel, 3, arc shaped blade.
The specific embodiment
Describe particular content of the present invention in detail below in conjunction with the drawings and specific embodiments.
As shown in the figure, spray ammonia blender comprises: flue 1, circular channel 2, arc shaped blade 3.Be provided with several circular channels 2 in the inside of flue 1, the circular channel 2 interior arc shaped blades 3 that some rotations distributions are set.
Owing in flue 1, being provided with several circular channels 1, and in circular channel 2, be provided with the arc shaped blade 3 that several rotations distribute, during use, the ammonia that sprays into and flue gas enter the circular channel 2 of this spray ammonia blender, under the effect of arc shaped blade 3, ammonia and flue gas aggravation turbulent flow fully mix in the scope of small distance, the mixing distance of flue gas is dwindled greatly, has improved simultaneously the mixed effect of flue gas.
Claims (1)
1. spray ammonia blender comprises: flue, circular channel, blade is characterized in that: be provided with several circular channels in the inside of flue, be provided with several arc shaped blades in circular channel, described arc shaped blade is for being fixed in the circular channel, and described some arc shaped blades are arranged in same plane.
