Abstract
Cooling tower noise reduction system, it relates to noise treatment technical field. It includes around the sound insulation steel sheet of cooling tower round and installs the air -out silencer at the cooling tower top, still be provided with the air inlet silencer between sound insulation steel sheet and the air -out silencer, the air -out silencer is the smooth tubbiness in surface, the air -out silencer includes air intake, air outlet, muffler plate, is provided with a plurality of muffler plates between air intake, air outlet, the muffler plate is "j" type, forms the noise elimination passageway between per two muffler plates. The utility model discloses the air output of cooling tower is neither influenced, its noise can be reduced again.
Description
Technical field
The utility model relates to technical field of noise treatment, particularly relates to a kind of cooling tower noise reduction system.
Background technology
Cooling tower Main Noise Sources is trickle noise, mechanical rotational noise, aerodynamic noise, and trickle noise frequency is higher, can reduce trickle noise by a relatively large margin with sound absorbing-insulating.Suction silencer only considers blower fan string sound downwards, and therefore air-inlet sound eliminator adopts vertical setting, can obtain defening effect, can eliminate again trickle direct projection sound.Blower fan rotational noise considered by air outlet silencing device, air pertormance eddy current crack.
Utility model content
The purpose of this utility model is to provide the cooling tower noise reduction system that a kind of air output is large, noise is little.
In order to solve problem existing in background technology, the utility model is by the following technical solutions: it comprises the sound insulation steel plate enclosed around cooling tower one and the air outlet silencing device being arranged on cooling tower top, also air-inlet sound eliminator is provided with between described sound insulation steel plate and air outlet silencing device, described air outlet silencing device is ganoid tubbiness, described air outlet silencing device comprises air inlet, air outlet, muffler plate, multiple muffler plate is provided with between air inlet, air outlet, described muffler plate, in " Pie " type, forms silencing channel between every two muffler plates.
The utility model neither affects the air output of cooling tower, reduces windage and turn eliminates the direct projection sound of blower fan of cooling tower to silencer top.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model air outlet silencing device.
Detailed description of the invention
See Fig. 1-2, a kind of cooling tower noise reduction system, it comprises the sound insulation steel plate 1 enclosed around cooling tower one and the air outlet silencing device 2 being arranged on cooling tower top, air-inlet sound eliminator 3 is also provided with between described sound insulation steel plate 1 and air outlet silencing device 2, described air outlet silencing device 3 is ganoid tubbiness, described air outlet silencing device 2 comprises air inlet 4, air outlet 5, muffler plate 6, multiple muffler plate 6 is provided with between air inlet 4, air outlet 5, described muffler plate 6, in " Pie " type, forms silencing channel between every two muffler plates 6.
Because trickle noise frequency is higher, so trickle noise can be reduced by a relatively large margin with sound absorbing-insulating, adopt vertically disposed air-inlet sound eliminator significantly can reduce the downward string sound of mechanical rotational noise simultaneously, can eliminate again trickle direct projection sound, and top air outlet silencing device upwards can reduce air pertormance eddy current crack.
When cool exterior air enters after cooling tower through air-inlet sound eliminator, cooled tower hot water heating is hot-air, the comparatively smooth tubbiness in surface made by air outlet silencing device, the hot pressing of gas makes hot-air discharge from the air outlet silencing device of top chimney-like, the hot pressing produced is utilized to overcome air intake, the resistance of air outlet silencing device, consider during calculating that the air rising hot pressing that hot pressing produces is greater than silencer resistance, noise reduction can be reached like this, do not affect again the ventilation of cooling tower, meet the normal result of use of cooling tower.When the air draft of air-cooled heat pump group, the air molecule of discharging can be entered formation silencing channel in an orderly manner after bottom muffler plate " Pie " type, thus decreases windage, and air quantity impact is very little, discharge from air outlet finally by top silencing channel, because this eliminating the direct projection sound of blower fan to silencer top.
