Description
Technical field
It the utility model is related to atmosphere pollution and administer field, be atomized more particularly, to a kind of rear end exterior mixing hollow
Bore denitration spray gun.
Background technology
The spray gun that denitrification apparatus uses at present is typically double-current spray gun body, is broken into liquid reducer using compressed air
After droplet, compressed air and liquid mixing, the gas-liquid mixture for possessing kinetic energy projects from shower nozzle, and formation has certain angle
It is preced with the mist of scope.
The mixed aerosol device of many spray guns is arranged on the shower nozzle of spray gun, and shower nozzle directly contacts the high temperature cigarette in burner hearth
Gas.Temperature in burner hearth is at 900 DEG C or so, and the atomizing air of spray gun contains substantial amounts of oxygen, and ammoniacal liquor has corrosion
Property, under high temperature, oxidation, the multiple action of corrosive substance, the life-span of shower nozzle is not very long, if shower nozzle has mixing fog
Change acts on, and shower nozzle damage means that spray gun damages.
For mixed gas, liquid, and give gas, liquid bigger kinetic energy, gas-liquid two would generally be designed inside spray gun
Pipeline, and design some internals such as some trunnions, necking, flow deflector.Under burner hearth hot environment, if these component quilts
If burning out, the atomizing effect of spray gun will be influenceed.Spray gun must just be changed.
Utility model content
The utility model is to overcome at least one defect (deficiency) described in above-mentioned prior art, there is provided is mixed outside a kind of rear end
Formula is atomized hollow cone denitration spray gun.
In order to solve the above technical problems, the technical solution of the utility model is as follows：A kind of rear end exterior mixing is atomized hollow cone
Denitration spray gun, including mixed aerosol device, barral of a gun, shower nozzle, the mixed aerosol device connect barral of a gun, the barral of a gun connection spray
Head,
The mixed aerosol device is threeway, and one end connection barral of a gun, one end is liquid reducer entrance, and one end is empty for compression
Gas entrance.
Further, mixed aerosol device is external, in spray gun rear end.
Further, the shower nozzle is carbon fiber shower nozzle.
Further, the shower nozzle removably connects barral of a gun.
Further, compressed air inlet includes rotating channel in the mixed aerosol device.
Further, it is provided with guide vane in the mixed aerosol device.
Compared with prior art, the beneficial effect of technical solutions of the utility model is：
The mixed aerosol device of spray gun is arranged on spray gun rear end, liquid reducer and compressed air and sprayed by the utility model
Gun back end carries out mixed aerosol away from burner hearth high temperature location, and body of spray gun rifle delivered inside is the gas-liquid mixed being atomized completely
Thing.
Only have without any choked flow part, the anterior hollow cone shower nozzle of spray gun inside the utility model body of spray gun rifle and shower nozzle
Adjust the effect of mist hat angle and scope.Even if shower nozzle has a damage, ejection be still minimum particle diameter droplet.
The utility model separates mixed aerosol device with shower nozzle, makes the atomizing effect of spray gun not influenceed by shower nozzle, simultaneously
The structure of shower nozzle is simplified, makes to reduce fault rate without any choked flow part inside it.Shower nozzle, which is burnt out, only to be needed to change shower nozzle i.e.
Can, it is not necessary to change whole spray gun.
The utility model reduces the fault rate of spray gun, extends the life-span of spray gun, and shower nozzle can be ensured by one
Still there is good atomizing effect in the case that setting loss is bad,
