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 system employs a five-layer air guide plate snap-fit and sound-absorbing column support structure inside the silencer. The air guide plate is spiral-shaped to increase the gas residence time, and the sound-absorbing columns are conical at both ends to reduce thrust. Combined with the inner wall of the sleeve made of memory material attached to the smoke outlet, a reasonable airflow guidance and sound absorption structure is formed.
It effectively increases the residence time of flue gas in the device, enhances the noise reduction effect, reduces the thrust of wind on the device, and improves the noise reduction performance.

[0003] The utility model aims at providing a kind of industrial smoke exhaust noise reduction device, can solve the problems, such as the limited effect of traditional industrial smoke exhaust device in noise reduction.
[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:
[0005] The utility model relates to a kind of industrial smoke exhaust noise reduction device, mainly by muffler, sleeve, air guide disc, sound absorption column, sleeve inner wall composition.
[0006] As preferred, in the embodiment, the muffler inside contains five layers of air guide disc buckle, and the support of sound absorption column, wherein the small interval of five buckles is 2cm, the middle interval is 20cm, and the large interval is 40cm.
[0007] As preferred, in the embodiment, the inside of the sleeve contains sleeve inner wall, and the sleeve is a cube, which is buckled at the smoke outlet, and the periphery above the sleeve is chamfered.
[0008] As preferred, in the embodiment, the thickness of the air guide disc is 2cm, and the air guide disc inside contains air guide hole, which is spiral, and the air guide hole guides the gas to be spiral, increases the time of gas staying inside the utility model, to increase the noise reduction effect, and the air guide disc is located between the small interval of five air guide disc buckles inside the muffler, and the air guide disc is in a fixed state and does not rotate with the gas.
[0009] As preferred, in the embodiment, the height of the sound absorption column is 35cm, and both ends are conical, which aims to reduce the contact area and thus reduce the thrust of the air below, and the sound absorption column is located between the large interval of five air guide disc buckles inside the muffler.
[0010] As preferred, in the embodiment, the sleeve inner wall is a memory material, which is in a state of wide outside and tight inside, at this time, the sleeve inner wall can be well attached to the smoke outlet.
[0011] Compared with the existing processing mode, the beneficial effects of the industrial exhaust fume noise reduction device are that the inside of the muffling pipe contains five layers of air guide disc buckles and sound absorption column supports, which can effectively guide the flow of flue gas and increase the residence time of flue gas in the device by reasonable interval arrangement, thereby improving the noise reduction effect. The sound absorption column is 35cm high and conical at both ends, which reduces the contact area and thus reduces the thrust brought by the air below. The sound absorption column is located between the large intervals in the inside of the muffling pipe and cooperates with the air guide disc to further improve the noise reduction effect.
