Description

Novel air cap of spray gun nozzle

Technical Field

The application relates to denitration spray gun technical field especially relates to a novel spray gun shower nozzle air cap.

Background

In the occasions such as steel plant, power plant, pulping and paper mill, waste incineration plant, etc., the application fields such as desulfurization, denitrogenation and other harmful gas, it is the two-fluid spray gun shower nozzle of two kinds of media of gas and liquid that all adopt, when two-fluid spray gun shower nozzle normally worked, need supply the compressed air of certain pressure and the liquid medium of certain pressure to the spray gun shower nozzle, the compressed air and the liquid medium through striking many times, mix in spray gun shower nozzle inside, produce tiny granule, after being mixed by atomizing granule and high temperature flue gas, produce chemical reaction, thereby reduce sulfur dioxide or nitrogen oxide content in the flue gas, reduce the flue gas temperature fast simultaneously, thereby restrain the production and the emission of dioxin and furan.

At present, all desulfurization, denitration and cooling spray guns are installed in a boiler furnace or a flue, and the existing air cap spray shape is single-hole solid cone spray, so that the spray area is limited, and the spray particle size sprayed is large, so that the spray effect is poor.

SUMMERY OF THE UTILITY MODEL

The application provides a novel spray gun shower nozzle air cap to solve current air cap spraying shape and be the solid awl of haplopore and spray, it is limited to spray the area, and the spraying particle diameter that sprays simultaneously is great, leads to the not good problem of injection effect.

The above technical purpose of the present invention can be achieved by the following technical solutions:

the utility model provides a novel spray gun shower nozzle air cap, this air cap includes the body, the body includes the jet orifice, the jet orifice head is provided with the V-arrangement groove.

Further: the included angle degree of the V-shaped groove is 0-90 degrees.

Further: the included angle degree of the V-shaped groove is 60 degrees.

Further: the body is connected with a base used for being connected with a spray head through threads, a plurality of layers of connecting layers are arranged in the base, and the layers of connecting layers are connected through the threads from inside to outside.

Further: the diameters of the edges of the multilayer connecting layers from inside to outside are reduced in sequence.

Further: the body is made of silicon carbide.

The technical scheme provided by the application comprises the following beneficial technical effects:

the air cap changes the spraying shape of the original air cap, namely a V-shaped groove is cut at the original spraying hole along the center of the spraying hole, so that the original single-hole solid cone spraying is changed into fan-shaped spraying, the spraying area of a spraying gun nozzle is enlarged, the spraying particle size is reduced, the spraying atomization is finer and more uniform, and the spraying effect is improved;

the specific development is as follows:

1. the angle of the V-shaped groove is changed by the fact that the included angle degree of the V-shaped groove is 0-90 degrees, so that the angle of sector spraying can be changed, and the spraying effect can be adjusted according to the actual situation;

2. the included angle degree of the V-shaped groove is 60 degrees, so that the spray atomization is finer and more uniform, and the spray effect is optimal;

3. the base with the multiple connecting layers is arranged, so that the base can be suitable for spray heads with different sizes and diameters, when the diameter of the spray head is larger, the base with the multiple connecting layers is matched with the spray head in size by removing part of the connecting layers, and the spray head can be used without producing air caps with various models, so that the production cost is saved;

4. the diameters of the edges of the multiple connecting layers from inside to outside are sequentially reduced, so that an operator can conveniently grasp the edges of the inner connecting layers when taking down the connecting layers;

5. the air cap is made of silicon carbide, so that the size precision can be guaranteed, the hardness of parts is improved, and the internal corrosivity and the wear resistance of the air cap are improved.

Detailed Description

Examples

As shown in figure 1, the novel air cap for the spray gun nozzle comprises a body 1, wherein the body 1 comprises a spray hole 2, a V-shaped groove 3 is formed in the head of the spray hole 2, the included angle degree range of the V-shaped groove 3 is controlled to be 0-90 degrees, and preferably, the included angle degree of the V-shaped groove 3 is 60 degrees.

Referring to fig. 2, the body 1 is connected with a base 4 for connecting a spray head through threads, a plurality of connecting layers 41 are arranged in the base 4, the plurality of connecting layers 41 are connected through threads from inside to outside, and the diameters of the edges of the plurality of connecting layers 41 from inside to outside are reduced in sequence.

The body 1 is made of silicon carbide, so that the size precision can be guaranteed, the hardness of parts is improved, and the internal corrosivity and the wear resistance of the air cap are improved.

The working principle is as follows: the air cap changes the spraying shape of the original air cap, namely, a V-shaped groove is cut at the original spraying hole along the center of the spraying hole, so that the original solid cone spraying of a single hole is changed into fan-shaped spraying, the spraying area of a spraying gun nozzle is enlarged, the spraying particle size is reduced, the spraying atomization is finer and more uniform, and the spraying effect is improved.
