AI Technical Summary
Traditional industrial smoke extraction devices have limited effectiveness in noise reduction and are unable to meet increasingly stringent environmental protection requirements and the needs of workers.
The design incorporates multiple air guide plates and sound-absorbing columns inside the silencer pipe. The air guide plates have air guide holes, and the sound-absorbing columns are located inside the silencer pipe. The air guide holes are spiral-shaped, and the two ends of the sound-absorbing columns are conical. By rationally setting the spacing of the air guide plates and the structure of the sound-absorbing columns, the flow of flue gas is guided and its residence time in the device is increased.
It effectively improves the noise reduction effect of industrial smoke exhaust devices by rationally guiding the flow of flue gas and increasing the gas residence time, thus significantly enhancing the noise reduction performance.

[0006] Further, the distance between the first wind guide disc and the second wind guide disc, the third wind guide disc and the fourth wind guide disc, and the fourth wind guide disc and the fifth wind guide disc is 20 cm, and the distance between the second wind guide disc and the third wind guide disc is 40 cm.
[0007] Further, the inner wall of the sleeve is wide at the bottom and narrow at the top, which is used to closely fit the smoke outlet.
[0008] Further, the outer periphery of the cube above the sleeve is provided with a chamfer.
[0009] Further, the thickness of the wind guide disc is 2 cm, and the wind guide disc is fixed between the small intervals in the five layers of wind guide disc buckles inside the muffler pipe, and the small interval distance in the wind guide disc buckle is 2 cm.
[0010] Further, the wind guide hole in the wind guide disc is spiral.
[0011] Further, the height of the sound absorption column is 35 cm, and the two ends of the sound absorption column are conical.
[0012] The application has the following beneficial effects:
[0013] By reasonably setting the interval and sound absorption column of the wind guide disc in the muffling pipe, the smoke flow can be effectively guided, the time of the smoke staying in the device is increased, and the noise reduction effect is improved. The height of the sound absorption column is 35 cm, and the two ends are conical, thereby reducing the contact area and the thrust brought by the air below. The air guide holes in the wind guide disc are spiral, the air guide holes guide the gas to be spiral, increase the time of the gas staying in the device, and increase the noise reduction effect. The sound absorption column is located between the second and third wind guide discs in the muffling pipe, and cooperates with the wind guide disc, further improving the noise reduction effect.
