Description
Technical field
The utility model is related to gas denitrifying technology field, particularly a kind of denitration rifle.
Background technology
Attention with country to environmental protection, the standard of boiler smoke discharge is more and more stricter, and wherein NOx discharge is by original
Do not require, newly-built heat power plant boiler discharge≤100mg/m3 after 2012, existing thermal power plant pot are required till now
Fire grate, which was put into after 2014, will also be down to≤100mg/m3.Therefore, the NOx that source-burning to boiler NOx is produced is original dense
The control requirement of degree is also with regard to more and more higher.
Be mostly to the elimination of NOx in boiler in the prior art by denitration spray gun by reducing agent as diluted after ammoniacal liquor to pot
Smog is sprayed in stove, reacts to reach the purpose of denitration by ammoniacal liquor and NOx.
Chinese patent such as Publication No. CN203437031U discloses a kind of SNCR denitration two-fluid injection apparatus, including
Gun body component and nozzle component；Wherein, the nozzle component is welded in one end of gun body component, and a protective case is arranged with thereon
Head；The nozzle component is provided with a nozzle reducing agent import, nozzle atomization air inlet, nozzle cooling wind inlet, reducing agent atomization
Outlet, cooling air outlet and atomization wind reducing agent mixing chamber；The nozzle reducing agent import, nozzle atomization air inlet, reduction
Agent atomisation outlet is connected with atomization wind reducing agent mixing chamber respectively；Led in the atomization wind reducing agent mixing chamber provided with a taper
Stream interface；The nozzle cooling wind inlet is connected with cooling air outlet.
The injection apparatus carries out cutting by conical flow guiding in face of reductant solution, so that reducing agent is formed when spraying
Preferable atomizing effect, so as to increase the response area of reducing agent and NOx in flue gas, is allowed to fully reaction, lifts denitration effect.
But it is to be directly welded at that conical flow guiding face, which is provided in inside nozzle component and nozzle component, in the injection apparatus
Gun body component one end, and be made of metal, after the use of long period, reducing agent such as ammoniacal liquor can be right. more in conical flow guiding the face
Conical flow guiding face, which is formed, corrodes and then influences taper guide face to spraying the atomizing effect of ammoniacal liquor, and now then needs to change whole
Injection apparatus causes replacement cost larger to ensure the atomizing effect of ammonia water spray.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of denitration rifle, the denitration rifle can have
Effect reduces replacement cost.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of denitration rifle, including gun body, fluid chamber is provided with along gun body length direction, and fluid chamber is provided with gas
Chamber, described gun body one end is bolted with atomizing mouth, and the fluid chamber is connected with air chamber in atomizing mouth one end, the atomizing mouth center
Through hole is provided with, atomizing mouth end face outside is welded with a J-type part, the vertical atomizing mouth end face outside in J-type part one end and grafting thereon
There is an atomization cone, atomization cone tip is alignd with the through hole center of circle.
Using said structure, the ammonia spirit sprayed from through hole passes through the peptizaiton formation atomized liquid of atomization cone, together
When be arranged on the atomizing mouth being spirally connected with gun body one end due to atomization cone, and atomization cone and atomizing mouth grafting are set, so
After the use of long period, atomization cone is damaged when needing to change, and directly can be pulled up from atomizing mouth, then plug new atomization
Cone, or whole atomizing mouth is screwed off, the atomizing mouth more renewed need not so be carried out more to whole denitration rifle
Change, so as to reduce replacement cost.
Being further arranged to the atomization cone includes mounting seat and the cone being connected with mounting seat, and the mounting seat is just
Hexagon, the J-type part end indent is provided with the depressed part being engaged with mounting seat.
Using said structure, it is only necessary to which the mounting seat of regular hexagon is inserted into positive six side that J-type part end matches therewith
The depressed part of shape can complete to be atomized the installation of cone.
The atomization cone is further arranged to be made of ceramic materials.
Using said structure, ceramics all have excellent corrosion resistance to the ammoniacal liquor of various concentration and temperature, and atomization cone is adopted
The service life of atomization cone can effectively be extended with ceramic material.
It is further arranged to that the adpting flange for being used for being connected with boiler is housed in the gun body.
Using said structure, more conveniently the denitration rifle can be attached with boiler by adpting flange.
The gun body, atomizing mouth and J-type part is further arranged to be made up of the material of stainless steel 321.
Using said structure, 321 stainless steels are Ni-Cr-Ti type austenitic stainless steels, and it has stronger wear-resisting and heat-resisting
Property, it is usually used in manufacturing lining, the conveyance conduit of wear-resisting sour container and wearable device, uses it for gun body, atomizing mouth and J-type part
Manufacture can be further ensured that the service life of whole denitration rifle.
In summary, the utility model has the advantages that：
1. when atomization cone, which is damaged, to be needed to change, directly it can be pulled up from atomizing mouth, then plug new atomization cone i.e.
Can, change conveniently and replacement cost is relatively low；
2. atomization cone is made of ceramic material, it can effectively extend the service life of atomization cone, it is ensured that the mist of ammoniacal liquor
Change effect.
