Abstract
The utility model relates to a sound absorption and noise reduction device and particularly relates to a sound absorption and noise reduction device for a cooling tower. The sound absorption and noise reduction device for the cooling tower comprises a foam aluminum sound absorption and noise reduction screen, wherein the foam aluminum sound absorption and noise reduction screen is arranged on an air inlet channel and/or a top air outlet of the cooling tower. Compared with the prior art, the sound absorption and noise reduction device adopts foam aluminum which has a good sound absorption effect and is water-proof, environment-friendly, small in air resistance, convenient to detach, convenient to maintain and long in service life to carry out sound absorption and noise reduction on the cooling tower, so as to avoid conditions that a waterproof measure of an existing sound absorption cotton material is not in place or damages are caused in a mounting process to cause that water in the air is adsorbed on the cotton surface in a sound absorption process and then slowly penetrates into the cotton, the sound absorption effect of the sound absorption cotton is reduced, even the sound absorption function is lost, the noise reduction of the cooling tower cannot reach the standards, the investment is wasted and a huge sum of technical improvement cost is increased.
Description
Technical field
The utility model relates to a kind of noise eliminating silencer, particularly a kind of used for cooling tower absorbing sound and lowering noise device.
Background technology
Cooling tower is a kind of cooling water circulating device be widely used in civil buildings and industrial system, the environment around its noise produced when operation directly affects.The noise that cooling tower sends mainly consists of the following components: the air power noise that 1, axial flow blower produces rotational noise and eddy current crack, consist of, and this noise is divided into air intake noise and air draft noise; 2, trickle noise, filler and the water-collecting tray of this partial noise in the potential energy impingement tower of water produces; 3, the mechanical noise that motor and drive disk assembly produce.The noise of cooling tower mainly be take air power noise that axial flow blower produces as main, is secondly the trickle noise.In addition, due to the outlet at cooling tower of the assembling of cooling tower, therefore, the exhaust outlet noise of cooling tower is higher than the noise of air inlet.For these noises, people have adopted the method for various noise elimination noise reductions.At present, the cooling tower sound absorption and noise reduction materials that adopt are the cotton plates of perforated sound-absorbing more, due to the low restriction of acoustical cotton material resistance to water, when moisture in air is larger, acoustical cotton can slowly be penetrated into airborne water adsorption more cotton inner on cotton surface, at this moment the sound-absorbing effect of acoustical cotton can reduce, and even is reduced to the forfeiture sound absorption function.
The utility model content
The utility model purpose is to provide a kind of used for cooling tower absorbing sound and lowering noise device, to solve the cooling tower sound absorption and noise reduction of the prior art materials that adopt, are the cotton plates of perforated sound-absorbing more, due to the low restriction of acoustical cotton material resistance to water, when moisture in air is larger, acoustical cotton can slowly be penetrated into airborne water adsorption more cotton inner on cotton surface, at this moment the sound-absorbing effect of acoustical cotton can reduce, and even is reduced to the technical matters of losing sound absorption function.
The utility model purpose is achieved through the following technical solutions:
A kind of used for cooling tower absorbing sound and lowering noise device, comprise foamed aluminium absorbing sound and lowering noise screen, and described foamed aluminium absorbing sound and lowering noise screen is arranged on air intake passage and/or the top outlet inlet of cooling tower.
Preferably, described foamed aluminium absorbing sound and lowering noise screen comprises framework and some blocks of foamed aluminiums, and described foamed aluminium is arranged in described framework.
Preferably, described foamed aluminium absorbing sound and lowering noise screen is arranged on the air intake passage of cooling tower, is provided with the first track support in described air intake passage, and described framework can push described the first track support, and can in described the first track support, slide.
Preferably, described foamed aluminium absorbing sound and lowering noise screen is arranged on the top outlet inlet of cooling tower, and described top outlet inlet is provided with the second track support, and described framework can push described the second track support, and can in described the second track support, slide.
Preferably, described foamed aluminium absorbing sound and lowering noise screen surfaces is equipped with electric-heating belt.
Preferably, described foamed aluminium absorbing sound and lowering noise screen surfaces is equipped with electric-heating belt.
Compared with prior art, the utility model has following beneficial effect:
1, the utility model adopts that sound-absorbing effect is good, not water funk, environmental protection, windage foamed aluminium little, long service life carry out absorbing sound and lowering noise to cooling tower; can avoid occurring that existing acoustical cotton material can be by airborne water adsorption on cotton surface when not in place or installation damage makes sound-absorbing because of waterproof measure; slowly be penetrated into again cotton inner; cause the sound-absorbing effect of acoustical cotton to reduce; even be reduced to the forfeiture sound absorption function; make the cooling tower noise reduction not reach standard; waste is invested, and increases the situation of huge technological transformation expense;
2, the utility model also can be avoided because of acoustical cotton material (being mainly mineral wool) bad sealing; in cotton, fiber exposes floating; affect environmental protection; and because mineral wool consists of glass fibre, although itself is nontoxic, a large amount of glass fibres of the long-term suction of staff; be deposited in lung; can produce serious harm to people's lung, pneumoconiosis changes, and exists the situation of occupational health risk to occur;
3, foamed aluminium absorbing sound and lowering noise screen of the present utility model can freely be extracted cleaning out, change sound-absorbing material;
4, install electric-heating belt additional on foamed aluminium absorbing sound and lowering noise screen surfaces of the present utility model, can prevent after heating that the absorbing sound and lowering noise screen surfaces from freezing;
5, foamed aluminium absorbing sound and lowering noise screen of the present utility model is via material, windage is little, with existing acoustic damping materials, compare, can reduce cooling tower air intake and exhaust resistance, construction unit can optimize cooling tower structure and reduce power of fan in the design phase, reduce initial cost, save station service, thereby reduce energy consumption.
The accompanying drawing explanation
The structural representation that Fig. 1 is cooling tower of the present utility model;
Fig. 2 is the structural representation that foamed aluminium absorbing sound and lowering noise screen of the present utility model coordinates with track support;
The part-structure schematic diagram that Fig. 3 is used for cooling tower absorbing sound and lowering noise device of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, describe the utility model in detail.
Refer to Fig. 1-3, used for cooling tower absorbing sound and lowering noise device of the present utility model, comprise foamed aluminium absorbing sound and lowering noise screen, and foamed aluminium absorbing sound and lowering noise screen is arranged on air intake passage 2 and/or the top outlet inlet 1 of cooling tower 10.In this example, in order to obtain better absorbing sound and lowering noise effect, at air intake passage 2 and top outlet inlet 1 place, all be provided with foamed aluminium absorbing sound and lowering noise screen.
