The first silencer structure is fixed to the air inlet, and the second silencer structure is fixed to the air outlet to reduce noise. The first silencer structure and the second silencer structure are respectively arranged at the air inlet and the air outlet to reduce overall noise, reduce noise pollution, and improve the working environment.

[0004] As the existing devices including the above patents are used, the shortcomings of the technology are gradually exposed, mainly in the following aspects:

[0005] First, the existing noise reduction structures are all set inside the cooling tower, which affects the layout and use of the internal space of the cooling tower.

[0006] Second, existing noise reduction structures are complex, large in size, high in cost, and have mediocre noise reduction effects.

[0007] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0008] In response to the defects in the existing technology, the utility model provides a mist-eliminating cooling tower with noise-reducing louvers to solve the problems that the traditional technology sets a noise reduction structure inside the cooling tower, which affects the layout and use of the internal space of the cooling tower; and the existing noise reduction structure is complex, large in size, high in cost, and has a general noise reduction effect.

[0009] To achieve the above objectives, the present invention provides the following technical solutions:

[0010] The demisting cooling tower with noise reduction shutters comprises a cooling tower, an air inlet is provided on the wall of the cooling tower, a noise reduction shutter is fixed in the air inlet, and the blades of the noise reduction shutter are synchronously swung.

[0011] The blades of the sound-absorbing shutter are provided with a sound-absorbing cavity, and the sound-absorbing cavity is provided with sound-absorbing cotton.

[0014] As an optimized solution, the cross-section of the sound folding plate is triangular, one side of the sound folding plate is in contact with the blades between adjacent sound folding plates, the other side of the sound folding plate is in contact with the lower surface of the sound folding plate, and the third side of the sound folding plate extends downward from the lower end of the sound folding plate toward the blades.

[0015] As an optimized solution, the sound-absorbing shutter includes a rectangular frame fixedly connected to the air inlet, and a plurality of blades are hingedly connected to opposite inner walls of the rectangular frame in parallel from top to bottom.

[0016] As an optimized solution, connecting rods are respectively fixed to the outer walls of several blades, and several connecting rods are hinged to the linkage rod.

[0017] As an optimized solution, an electric telescopic cylinder is hinged on the outer wall of the cooling tower below the air inlet, and the telescopic end of the electric telescopic cylinder is hinged to the lower end of the connecting rod.

[0018] As an optimized solution, a lower hinge seat is fixedly connected to the outer wall of the cooling tower, and the cylinder end of the electric telescopic cylinder is hinged to the lower hinge seat.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

Since the noise-reducing louver blades are equipped with sound insulation cotton and the air inlet is closed, the noise inside the tower will be blocked, thereby reducing the noise value near the external louver of the mist-eliminating cooling tower.

[0024] By setting up silencer shutters at the air inlet, the influence of the silencer components set inside the cooling tower on the internal space can be effectively prevented, thereby ensuring the normal internal space of the cooling tower. In addition, the device has a simple structure, a small size, a low production cost, and can improve the noise reduction effect. BRIEF DESCRIPTION OF THE DRAWINGS
