Description
Technical field
This utility model relates to a kind of environment-friendlydenitration denitration device, a kind of ammonia water spray gun installing protection sleeve pipe additional.
Background technology
At present, being known in during power plant uses and have multiple ammonia water spray gun, ammonia water spray gun is arranged at boiler furnace outlet and rotation
Wind separator outlet, high concentrate dust, complicated air-flow environment at boiler furnace outlet.Traditional pressure type lance head is easy
Wearing and tearing, block, cause maintenance cost high, boiler internal temperature is high, and inside is filled with dust granules, and these granules be all
Flow at high speed.At high temperature, adding the dust granules abrasion to nozzle, ammonia water spray gun is easily broken.Ammonia water spray gun nozzle
Once being worn, spray gun will lose atomizing functions, and such liquid cannot be atomized, and is not atomized when liquid is encountered in boiler
Wall, may result in the damage of boiler material.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, it is provided that one is reasonable in design, using effect good
Install additional protection sleeve pipe ammonia water spray gun.
This utility model solves its technical problem and be the technical scheme is that
A kind of ammonia water spray gun installing protection sleeve pipe additional, including gun shot, compressed air spraying device, wear-resisting lance head, spray
One end of barral of a gun connects compressed air spraying device, and the other end of gun shot is provided with wear-resisting lance head, and compressed air spraying fills
Putting and be provided with compressed air inlet and ammonia import, on described gun shot, the one end near wear-resisting lance head is provided with protection set
Pipe, and protect sleeve pipe to interconnect with wear-resisting lance head, increase protection gun shot and atomizing effect, reduce operation
Cost.
Further, described protection sleeve pipe makes of having special steel material high temperature resistant, wear-resistant, acid and alkali-resistance characteristic.
Further, described wear-resisting lance head is coated with resistance to erosion, high temperature resistant, wear-resistant, acid and alkali-resistance material layer.
Ammonia water spray gun of the present utility model, its atomization angle is 30 ~ 110 degree, and droplet granule at 30 ~ 70um, flow is
30ml/h-300ml/h, mist field penetration capacity in flue gas is mixed homogeneously with flue gas by force, with the reaction of nitrogen oxides in flue gas more
Add fully, it is ensured that NO_x Reduction by Effective, the demand of various production status can be met.
Ammonia water spray gun of the present utility model has cooling function and disables choke preventing function, and spray gun can spray powder by compressed air
Dirt reaches the effect of cooling simultaneously, and gun design disables choke preventing function, it is ensured that spray gun is at high temperature, high concentrate dust, complicated
Air-flow environment is not extracted out spray gun and will not block spray gun yet.
A kind of installing additional of the present utility model protects the ammonia water spray gun of sleeve pipe compared with prior art, produced beneficial effect
It is:
This utility model has features such as reasonable in design, simple in construction, easy to use, function admirable, practicality, wear-resistant,
High temperature resistant, atomizing effect good, can be according to field working conditions change arbitrarily regulation, it is possible to meet various denitration work condition environment demand.Peace
Dress, maintenance are convenient, it is to avoid high temperature sintering, increase the service life, reduce operating cost, are greatly improved work efficiency.
Accompanying drawing explanation

In figure, 1, gun shot, 2, compressed air spraying device, 3, wear-resisting lance head, 4, protection sleeve pipe.
Detailed description of the invention
1 a kind of ammonia water spray gun installing protection sleeve pipe additional of the present utility model is said in detail below below in conjunction with the accompanying drawings
Bright.
As shown in Figure 1, of the present utility model a kind of install additional protection sleeve pipe ammonia water spray gun, its structure include gun shot 1,
Compressed air spraying device 2, wear-resisting lance head 3, one end of gun shot 1 connects compressed air spraying device 2, gun shot 1 another
One end is provided with wear-resisting lance head 3, and wear-resisting lance head 3 is coated with resistance to erosion, high temperature resistant, wear-resistant, acid and alkali-resistance material layer.Pressure
Compressed air inlet and ammonia import it is provided with, near wear-resisting lance head 3 on described gun shot 1 on contracting air blown device 2
One end is provided with protection sleeve pipe 4, and protecting pipe 4 makes of having special steel material high temperature resistant, wear-resistant, acid and alkali-resistance characteristic, and protects
Protecting pipe 4 interconnects with wear-resisting lance head 3.
Of the present utility model a kind of install additional protection sleeve pipe its processing and fabricating of ammonia water spray gun simple and convenient, by specification accompanying drawing
Shown processing and fabricating.
In addition to the technical characteristic described in description, it is the known technology of those skilled in the art.
