The SNCR denitration technology uses gradually at cement industry, is used for administering nitrogen oxide (NO
X) emission problem of exhaust emission.This technology is namely at subregion (850～1100 ℃ of temperature ranges) the injection reduction agent solution (urea or ammonia) of dore furnace and kiln tail smoke-box, with NO
XCarry out chemical reaction, generate the N of cleaning
2And water, reach the purpose of exhaust gas denitration.Nozzle sprays the module core as reducing agent, and its performance directly affects the effect of whole SNCR denitrating system.
Be used for the atomizer of the spray gun employing of denitrating system at present, mainly contain single-orifice type nozzle and fan nozzle.The single-orifice type nozzle, rigidity is big, and spouting velocity is fast, but stops up easily, and flow adjustment range is little, and area coverage is little; Fan nozzle, area coverage is big, but a little less than the rigidity, the high wind speed in the burner hearth influences its atomizing effect, reducing agent and NO
XReact insufficient, cause the reductant solution utilization rate to descend, for reaching qualified NO
XConcentration of emission needs to increase the denitration cost.
Summary of the invention
Technical problem to be solved: for improving the nozzle performance that is used for SNCR denitrating system spray gun, the invention provides a kind of X type two-fluid spray nozzle convenient, simple in structure, that flow adjustment range big, mist torch penetrability is strong, area coverage is big, anti-clogging is excellent, decay resistance is strong of changing.
Technical scheme: the invention provides a kind of 1, a kind of two-fluid X type nozzle in order to overcome the above problems, it is characterized in that: comprise shower nozzle, locking nut, nozzle boss, nozzle boss is fixed on the gun shot, locking nut connects as one shower nozzle and nozzle boss, nozzle boss arranges centre bore and is communicated with compressed air, peripheral uniform straight hole is communicated with liquid, be provided with hybrid chamber in shower nozzle inside, be provided with spray orifice at the shower nozzle head, and communicate with hybrid chamber, be provided with inclined hole in the shower nozzle rostral-caudal, and communicate with hybrid chamber, inclined hole communicates with straight hole, and straight hole communicates with hybrid chamber.
Described nozzle boss arranges helicitic texture and is connected with locking nut.

Contact by conical surface b between described shower nozzle and the locking nut.
High temperature resistant, wear-resisting alloy steel material that described shower nozzle, locking nut and nozzle boss all adopt.
The quantity of described spray orifice is 4～8.
Beneficial effect: design replacing of the present invention is convenient, simple in structure, flow adjustment range big, mist torch penetrability is strong, area coverage is big, anti-clogging is excellent, decay resistance is strong.
Description of drawings
Fig. 1 is scheme of installation of the present invention;
Fig. 2 is the uniform schematic diagram of the spray orifice 8 on the shower nozzle 1 among the present invention;
Fig. 3 is uniform straight hole 5 schematic diagrames on the nozzle boss 3 among the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figures 1 to 3, a kind of two-fluid X type nozzle, comprise shower nozzle 1, locking nut 2, nozzle boss 3, nozzle boss 3 is fixed on the gun shot 9, locking nut 2 connects as one shower nozzle 1 and nozzle boss 3, nozzle boss 3 arranges centre bore 4 and is communicated with compressed air, peripheral uniform straight hole 5 is communicated with liquid, be provided with hybrid chamber 7 in shower nozzle 1 inside, be provided with spray orifice 8 at shower nozzle 1 head, and communicate with hybrid chamber 7, be provided with inclined hole 6 in shower nozzle 1 rostral-caudal, and communicate with hybrid chamber 7, inclined hole 6 communicates with straight hole 5, and straight hole 5 communicates with hybrid chamber 7.
Described nozzle boss 3 arranges helicitic texture and is connected with locking nut 2.
Described straight hole 5 quantity are 2～10.
30 °～180 ° of 8 angle α of spray orifice scopes on the described shower nozzle 1,80 °～90 ° of the angle β scopes that inclined hole is 6.
Described shower nozzle 1 and nozzle boss 3 fit tightly by end face a, form hermetically-sealed construction.
Contact by conical surface b between described shower nozzle 1 and the locking nut 2.
Described shower nozzle 1, locking nut 2 and nozzle boss 3 all adopt high temperature resistant, wear-resisting alloy steel material.
The quantity of described spray orifice 8 is 4～8.
After nozzle installs, feed a certain amount of compressed air and liquid from gun shot respectively.After entering nozzle, high-speed liquid stream flow to inclined hole 6 on the shower nozzle 1 from the uniform straight hole 5 on the nozzle boss 3, impacts inclined hole 6, and liquid self impacts and mixes, and produces the initial stage spraying effect, through inclined hole 6 high-speed jets to the hybrid chamber inwall; High velocity air is injected into hybrid chamber from the centre bore 5 on the nozzle boss 3, fully mixes, impacts with the liquid granule, forms tiny and uniform atomizing particle, and the spray orifice 8 from shower nozzle 1 sprays.
When the nozzle maximum stream flow is determined, by regulating the fluid flow of the straight hole 5 on the nozzle boss 3, can regulate the actual flow of nozzle quickly and easily.
Regulate the range of atomized flow that compressed-air actuated pressure (between 0.4～0.7Mpa) changes nozzle.
When changing nozzle, only need locking nut 2 is screwed off, pull down the shower nozzle 1 of damage, qualified shower nozzle 1 is fitted on the nozzle boss 3, get final product tightening locking nut 2.
The atomization angle of nozzle is relevant with the spray orifice of shower nozzle with area coverage, can change the quantity of spray orifice and the angle between spray orifice as required.
The flow of nozzle is relevant with liquid flux on the space of hybrid chamber and the nozzle boss, can change length and the diameter of hybrid chamber as required, is communicated with the flux of liquid simultaneously on the corresponding change nozzle boss.
The above is the preferred embodiments of the present invention only, is not restricted to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within the claim scope of the present invention.
