Abstract
The utility model discloses a kind of Large Size Induced Draft Fans denoising device, denoising device comprises: air induction mast, gas outlet, denoising pipe, the wind inlet of described denoising pipe is connected with the air outlet of Vanes on Induced Draft Fan shell, its exhaust outlet is connected with gas outlet, denoising pipe is take gas outlet as the spiral wound structure of central authorities, being provided with material in described denoising pipe is stainless noise suppression network, tube wall is provided with the acoustical cotton that material is polyester fibre, denoising pipe total length is no less than 100 meters, diameter of section is no less than 0.6 meter, and the number of turns is no less than 3 circles.The mounting type that this device is general is the subsurface be embedded in below equipment, does not take space, workshop, and can change the number of turns of denoising pipe according to actual conditions, diameter and length, and structure is simple, substantially need not safeguard and noise reduction is very outstanding.
Description
Technical field
The utility model relates to a kind of device be applicable to induced draught fan noise abatement, is exactly specifically a kind of Large Size Induced Draft Fans denoising device.
Background technique
The noise of high-decibel can be sent when high speed and high pressure induced draught fan operates, often reach more than 80 decibels, can cause serious harm to the health of staff on the scene, therefore, need development a kind of with low cost, the simple and denoising device that is that easily safeguard of structure.
Model utility content
The purpose of this utility model is to provide a kind of Large Size Induced Draft Fans denoising device, and this device can play obvious noise reduction by the denoising pipe of spiral to the high velocity air that induced draught fan blows out.
The technical scheme in the invention for solving the technical problem is:
A kind of Large Size Induced Draft Fans denoising device, this device is connected with induced draught fan, induced draught fan comprises: motor, Vanes on Induced Draft Fan shell, wherein this Large Size Induced Draft Fans denoising device comprises: air induction mast, gas outlet, denoising pipe, the wind inlet of described denoising pipe is connected with the air outlet of Vanes on Induced Draft Fan shell, its exhaust outlet is connected with gas outlet, and denoising pipe is take gas outlet as the spiral wound structure of central authorities.Designed by said structure, the high velocity air sent from high speed induced draught fan is when by noise abatement pipeline, and noise can be weakened in a large number.
As a kind of optimal technical scheme: being provided with material in described denoising pipe is stainless noise suppression network, tube wall is provided with the acoustical cotton that material is polyester fibre.The noise of high velocity air can reduce and prevent noise from spreading out of in denoising pipe by noise suppression network and acoustical cotton gas further.
As further optimal technical scheme: denoising pipe total length is no less than 100 meters, diameter of section is no less than 0.6 meter, and the number of turns is no less than 3 circles.Can ensure that the noise reduction efficacy of this device improves further, reach more than 80%, noise be reduced to the sound that human body is not injured lower than 40 decibels.
In sum, the beneficial effects of the utility model are: the mounting type that this device is general is the subsurface be embedded in below equipment, do not take space, workshop, and the number of turns of denoising pipe can be changed according to actual conditions, diameter and length, structure is simple, substantially need not safeguard and noise reduction is very outstanding.
Accompanying drawing explanation
Fig. 1 is the utility model general structure plan view;
Fig. 2 is the structural representation of noise suppression network of the present utility model;
Fig. 3 is the structural front view of a kind of embodiment of the present utility model;
Fig. 4 is the structural front view of the concrete real-time mode of another kind of the present utility model.
Wherein, 1 motor, 2 blade enclosures, 3 air induction masts, 4 denoising pipes, 5 gas outlets, 6 acoustical cottons, 7 noise suppression networks.
Embodiment
As illustrated in fig. 1 and 2, a kind of Large Size Induced Draft Fans denoising device, wherein, induced draught fan comprises: motor 1, blade enclosure 2, this Large Size Induced Draft Fans denoising device comprises: air induction mast 3, gas outlet 5, denoising pipe 7, the wind inlet of described denoising pipe is connected with the air outlet of the blade enclosure 2 of induced draught fan, and its exhaust outlet is connected with gas outlet 5, denoising pipe 4 be with gas outlet 5 be central authorities spiral wound structure.Being provided with material in described denoising pipe 4 is stainless noise suppression network 7, tube wall is provided with the acoustical cotton 6 that material is polyester fibre.Denoising pipe 4 total length is no less than 100 meters, and diameter of section is no less than 0.6 meter, and the number of turns is no less than 3 circles.
In a kind of mode of execution as shown in Figure 3, the structure of denoising pipe 4 is spiral winding structure centered by gas outlet 5 and often encloses pipeline upwards to arrange successively, and it is little and can dig the situation of dell that this mode of execution is applicable to floor space, makes full use of space.
In another kind of mode of execution as shown in Figure 4, the structure of denoising pipe 4 is spiral winding structure centered by gas outlet 5 and often encloses pipeline to arrange in same level, this mode of execution is applicable to the large but situation about should not deep-cut of floor space, makes full use of space.
The advantage of the utility model embodiment is: can tackle the structure that multiple workshop situation changes denoising pipe flexibly, can abundant noise reduction by spiral noise-reduction pipeline and inner noise suppression network and acoustical cotton, structure is simple, substantially need not safeguard and noise reduction is very outstanding.
