Drip the sound splashed down.
The noise of cooling tower brings harm to society and influenceed, and the improvement to cooling tower buzz has been wanting for social development
Ask.Cooling tower of the prior art is seldom equipped with denoising device, and is provided with the occasion of silencer at some, is usually only
Air-out open height is increased, noise elimination air duct is made.But this measure effect is unsatisfactory, noise can not be prevented to upwardly propagate by it,
In the position for having high-rise residential area, it can also often cause the complaint of related resident.
The content of the invention
In order to solve deficiency of the prior art, the purpose of this utility model is that providing a kind of middle-size and small-size cooling tower eliminates the noise
Device, the problem of running noise and the noise transmission direction of cooling tower are solved emphatically.
The utility model solves the technical scheme that its technical problem used：
A kind of middle-size and small-size silencer for cooling tower, it is characterised in that：It is described including cooling tower body and air intake noise elimination structure
Air intake noise elimination structure is arranged on cooling tower body air inlet, and air intake noise elimination structure is the blinds being made up of some double-deck microwell plates
Quieter material is filled between structure, double-deck microwell plate.
The air outlet silencing structure being arranged at cooling tower body air outlet is further comprises, air outlet silencing structure is that a noise elimination is curved
Head, its bottom opening is connected with the air outlet of cooling tower body, and the side wall of bend muffler is made up of inner plating and lamina rara externa
Double-decker, is filled with quieter material between inner plating and lamina rara externa, inner plating uses AND DEWATERING FOR ORIFICE STRUCTURE.
Described air outlet silencing structure further comprises an adapter flange, and the bottom that adapter flange is used to connect bend muffler is opened
The air outlet of mouth and cooling tower body, the side wall of adapter flange is the double-decker being made up of inner plating and lamina rara externa, inner plating
Quieter material is filled between lamina rara externa, inner plating uses AND DEWATERING FOR ORIFICE STRUCTURE.
Described adapter flange bottom opening is the circular configuration matched with cooling tower body air outlet, adapter flange top
It is open as the square structure matched with adapter flange bottom opening.
In summary, the beneficial effects of the utility model are：Two main noise sources are operated for cooling tower and are designed,
The dB (A) of cooling tower motion means noise 10 ~ 15 is effectively reduced, is that subway station, high ferro station, the high-end residential close to residential block are small
The places such as area provide excellent low-noise cooling tower design.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side structure schematic diagram of the present utility model.
Fig. 3 is the structural representation of cooling tower body and adapter flange.
In figure：1 water tank, 2 cooling tower bodies, 3 maintenance doors, 4 air ducts, 5 staircases, 6 air inlet silencers, 7 adapter flanges, 8
Bend muffler, 9 double-deck microwell plates, 10 quieter materials, 11 inner platings, 12 inspection platforms, 13 quieter materials, 14 lamina rara externas.
Embodiment
Embodiment of the present utility model is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages of the present utility model and effect easily.
As shown in Figure 1, 2, 3：A kind of middle-size and small-size silencer for cooling tower, including cooling tower body 2 and air intake noise elimination structure, it is cold
But the bottom of tower body 2 is provided with water tank 1, and the side of cooling tower body 2 is provided with maintenance door 3, staircase 5, and the top of cooling tower body 2 is provided with inspection
Equating platform 12 and air duct 4, described air intake noise elimination structure are arranged on the air inlet of the both sides of cooling tower body 2, and air intake, which is eliminated the noise, to be tied
Structure is the louver structure being made up of some double-deck microwell plates 9, and the place of meeting that connects of double-deck microwell plate 9 uses riveting or welding procedure, double
Quieter material 13 is filled between layer microwell plate 9, can not only stop that the inner water droplets of cooling tower body 2 are splashed by air intake noise elimination structure
The sound fallen is outwards propagated, and is also acted on certain dash, and ensure that cool exterior air is smoothly entered in cooling tower.
The middle-size and small-size silencer for cooling tower further comprises the air outlet silencing structure being arranged at the air outlet of cooling tower body 2,
Air outlet silencing structure includes bend muffler 8 and adapter flange 7, and adapter flange 7 is used for the bottom opening for connecting bend muffler 8 and cold
