Abstract
The utility model relates to an ammonia spraying device comprising a spraying main pipe and a spraying branch pipe; and the spraying branch pipe is connected with the spraying main pipe and is provided with a nozzle. The ammonia spraying device is characterized in that the spraying main pipe is arranged at the outside of a mixed gas pipeline; the part of the spraying branch pipe, which is provided with the nozzle, is arranged in the mixed gas pipeline; and the spraying direction of the nozzle is vertical to the flowing direction of the limited outside gas of the mixed gas pipeline. The ammonia spraying device has simple structure and simple, convenient operation, good mixing effect of sprayed ammonia and the gas in the pipeline and little resistance to gas flow.
Description
Technical field
The utility model relates to a kind of ammonia spray equipment, belongs to environmental protection or chemical technology field.
Background technology
Adopt at present liquefied ammonia or ammoniacal liquor as reducing agent, with its with spray into flue after air mixes, under catalyst action, react the harmless nitrogen G﹠W eliminating system of generation with nitrogen oxide in the flue gas.At present what adopt is ammonia-spraying grid more, is about to some amonia adjutages and is arranged in the flue, and every amonia adjutage has some spray ammonia perforations, but because the design of the spray direction of existing jet flow barrier top nozzle is unreasonable, the spray mixed effect is not good enough.
The utility model content
For overcoming the above-mentioned defective of prior art, the utility model provides a kind of ammonia spray equipment, adopts this device can obtain mixed effect preferably.
The utility model realizes that the technical scheme of above-mentioned purpose is: a kind of ammonia spray equipment, comprise female pipe of spray and spray arm, described spray arm is connected with the female pipe of described spray, described spray arm is provided with nozzle, the female pipe of described spray is located at mist pipeline outside, the part that described spray arm is provided with described nozzle is located in the mist pipeline, and the injection direction of described nozzle is vertical with the flow direction of the extraneous gas that described mist pipeline limits.
All can be provided with valve on the described spray arm, so that spray the adjusting of pressure and spray flux according to the actual conditions of each arm.
The quantity of described spray arm is generally a plurality of.
The described spacing that respectively sprays arm can equate usually.
Described spray arm can be straight tube usually.
Nozzle quantity on the described spray arm usually can be for a plurality of, and the nozzle on the same spray arm can equidistantly distribute usually.
Described each structure of nozzle usually can be identical.
The female pipe of described spray can adopt welding manner to be connected or to connect by flange with described spray arm usually.
The described arm that respectively sprays usually can be in the same plane and be parallel to each other, and the female pipe of described spray is vertical with described spray arm.
Described mist pipeline can be rectangular duct usually, and the described arm that respectively sprays is parallel with a wall on the described rectangular duct, and equal in length.
The beneficial effects of the utility model are: because the flow direction of the nozzle on the spray arm is vertical with the flow direction of extraneous gas, can strengthen nozzle ejection ammonia mixed with intersecting of gas in the pipeline, strengthen the disturbance of gas, it is more even that ammonia is mixed with gas, improves mixed effect thus; Because the female pipe of spray is placed on the outside of mist, the spray arm is placed in the mist pipeline, like this can simplified structure, the isostasy that helps ammonia, because each spray arm all is furnished with valve, can open or close according to size and close a certain arm, or require to carry out the spray control of each arm according to different arm actual conditions and spray for the ammonia amount.
Description of drawings
Fig. 1 is a general structure schematic diagram of the present utility model.
Fig. 2 is and the corresponding partial structurtes schematic diagram that sprays arm of Fig. 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model provides a kind of ammonia spray equipment, comprises female pipe 1 of spray and spray arm 2, and described spray arm is connected with the female pipe of described spray, described spray arm is provided with nozzle 3, and described nozzle spray direction is vertical with the flow direction of extraneous gas.Strengthened extraneous gas like this and mixed with nozzle intersecting of ammonia of ejection, strengthened the disturbance of gas, it is more even that ammonia is mixed with gas.
The female pipe of described spray is located at mist pipeline 5 outsides, and the nozzle segment on the described spray arm is located in the mist pipeline, ammonia through female pipe and each spray arm after, from the nozzle ejection, evenly mix with gas in the mist pipeline.
Described spray arm all is furnished with valve 4, can be according to for the size adjustment of ammonia amount even close the spray of corresponding spray arm.
Nozzle on each spray arm is generally a plurality of, can suitably increase or reduce the quantity of nozzle according to the length and the spray requirement of mist pipeline.
The female pipe of described spray is connected for welding or by flange with described spray arm connected mode.
Usually the identical nozzle of structure can be adopted, but, also different nozzle diameters can be adopted according to the different requirements that spray distributes.
Described spray arm quantity is generally a plurality of, can some spray arms be set according to the volume size of mist pipeline.
The spacing of described spray arm equates, so that spray evenly mixes gas.
Described spray arm is straight tube or bend pipe, can this pipeline spray tube shape of adaptation be set according to the volume of actual mist pipeline.
