The spiral board 4 is equipped with multiple through-holes 401 of circular array distribution, and each through-hole 401 is close to the end of cap of spraying nozzle 7 to spray
The axis direction of mouth ontology tilts；The side wall of the nozzle body 1 is equipped with air inlet 3, and the air inlet 3 is located at feed liquor
Between entrance 2 and spiral board 4 and the inner wall of the airintake direction of the air inlet 3 and nozzle body is in tangent state；The eddy flow
The first eddy flow mixing chamber 5 is formed between plate 4 and liquid inlet 2, and it is mixed that the second eddy flow is formed between the spiral board 4 and cap of spraying nozzle 7
Room 6 is closed, the second eddy flow mixing chamber 6 is connected with the first eddy flow mixing chamber 5 by multiple through-holes 401.
Further, the spiral board 4 is tapered and vertex of taper is towards the rear end of nozzle body 1.
The utility model proposes a kind of denitration nozzle have the advantages that
The liquid entered by liquid inlet carries out first in the first eddy flow mixing chamber with the gas entered by air inlet
Secondary mixing then flows into the second eddy flow mixing chamber through spiral board in the case where the eddy flow of gas drives and carries out second of mixing, so that spray
Mist is more concentrated, droplet is more tiny, is more evenly distributed, to not easily cause coking and blocking at nozzle.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the technology of the utility model
Means can be implemented in accordance with the contents of the specification, and to allow the above and other objects, features and advantages of the utility model
It can be more clearly understood, it is special below to lift preferred embodiment, and cooperate attached drawing, detailed description are as follows:

Specific embodiment
Further to illustrate that the utility model is to reach technical means and efficacy used by predetermined purpose, below in conjunction with
Attached drawing and preferred embodiments, to according to the utility model proposes a kind of denitration nozzle its specific embodiment, structure, feature and its
Effect, detailed description is as follows.
It is according to definition "front", "rear" with the flow direction of liquid and gas in denitration nozzle body in the description of the present embodiment.
Referring to Fig. 1, a kind of denitration nozzle, including nozzle body 1,1 rear end of nozzle body are equipped with liquid inlet 2,
1 front end of nozzle body is equipped with cap of spraying nozzle 7, and the cap of spraying nozzle 7 is tapered, and the cap of spraying nozzle 7 is equipped with multiple spray orifices
701, multiple spray orifices 701 are distributed along axis circular array.Spiral board 4, the spiral board 4 are provided in the nozzle body 1
Tapered and taper vertex is equipped with multiple through-holes 401 to diagonally distribute towards the rear end of nozzle body 1, the spiral board 4,
The front end of the through-hole 401 is tilted to the axis direction of nozzle body 1, which can make through gas-liquid mixed herein
Object Pcnten-1 yne-4 more evenly, drop it is more tiny.The first eddy flow mixing chamber 5, institute are formed between the spiral board 4 and liquid inlet 2
It states and forms the second eddy flow mixing chamber 6 between spiral board 4 and cap of spraying nozzle 7, the second eddy flow mixing chamber 6 and the first eddy flow mixing chamber
5 are connected by multiple through-holes 401.The side wall of 1 rear end of nozzle body is equipped with air inlet 3, the air inlet 3
