Specific embodiment
In conjunction with the attached drawing in the utility model embodiment, to the technical scheme in the embodiment of the utility model carry out it is clear,
It is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole implementation
Example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
The every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of equipment of making nitrogen denoising device, including device noumenon 1, the dress
Setting ontology 1 includes air inlet pipe 2 and exhaust pipe 3.
Internal screw thread 4 is provided at the air inlet of the air inlet pipe 2, the inner wall of the air inlet pipe 2 is provided with screen casing 5, described
The outer wall of screen casing 5 is provided with sound absorption cotton layer 6, and the middle part of the screen casing 5 is provided with shutter board 7 perpendicular to the axis, the blinds
Abacus 9 is arranged in the side of plate 7, and the equidistant hole equipped with aperture 0.001-1mm on the orifice plate 9, the two sides of the orifice plate 9 are all provided with
It is equipped with vertical baffle 10, the orifice plate 9 is provided with Turbogrid plates 11 at separate air inlet pipe 2.
As shown in figure 3, the exhaust pipe 3 is internally provided with perforated pipe 12, the outside of the perforated pipe 12 is provided with bubble
