Description
Technical field
The present invention relates to a kind of falling water noise reducing device, relate in particular to the falling water noise reducing device in a kind of power generating plant cooling tower.
Background technology
Along with the fast development of power industry and improving constantly of environmental requirement, State Power Corporation has proposed concrete noise objective to newly-built cooling tower, and noise must reach relevant national standard, cooling tower do not have the noise reduction facility do not allow build.Also must carry out the noise reduction technology transformation by time limit for existing cooling tower, otherwise the rectification that just must stop production, noise is not up to standard will not be checked and accepted.At present, the most fibrous web-like de-noising pads that adopt of the cooling tower in each power plant reduce noise, the directly bump de-noising pad that falls into water, and its noise reduction is not obvious, and mesh is tiny, is very easily stopped up by impurity.The noise that existing cooling tower produces has seriously had influence on people's live and work environmental quality, becomes the pollution source of noise of the new period.In order effectively to reduce the drowning noise of cooling tower, the our factory is to disclose a kind of cooling tower falling water noise reducing device among the 01230431.X in the patent No., it is the cellular noise reducing plate of the pipe oblique arrangement formation of both ends open, though this denoiser has adopted the inclined-plane principle of noise reduction, making falls into water contacts with the inclined-plane of cellular board, its noise reduction is greatly improved than conventional netted de-noising pad, but lacks the drop energy-eliminating structure, also can produce the secondary noise.The denoising device that contains this cooling tower falling water noise reducing device is fixed on the top, pond, because this device is fixed on the top in pond by fixed mount, in actual use, the distance of end distance tank water face changes with the SEA LEVEL VARIATION in pond under the falling water noise reducing device, the noise reduction instability of this falling water noise reducing device is difficult to the noise reduction that reaches best.
Summary of the invention
In order to overcome the deficiency that existing cooling tower falling water noise reducing device exists, the invention provides a kind of floating type energy-eliminating noise-reducing device.
Technical scheme of the present invention is: a kind of floating type energy-eliminating noise-reducing device, form by noise reduction cellular board, support framework, buoyancy body, the noise reduction cellular board is arranged on the support framework, buoyancy body is arranged on the below of support framework, whole floating type energy-eliminating noise-reducing device is placed in the pond of cooling tower, distance≤200 of the following end distance tank water face of noise reduction cellular board millimeter.
Described noise reduction cellular board is that some PVC plastic molding boards combine, which is provided with the special pipe of several two end openings, each special pipe is provided with collecting pipe, inclined-plane hush tube, curved surface power consumption pipe from top to bottom successively, collecting pipe is vertically disposed straight tube-like, the inclined-plane hush tube is tilted-putted rectilinear tubes, is provided with multistage power consumption groove and splitter box on curved surface power consumption pipe.
The frame structure that described support framework is connected into by some fiberglass H-shaped materials, connecting rod, spacers; Described buoyancy body is a tubular body, and the tubulose buoyancy body is fixed on the below of support framework.
The height of described collecting pipe 〉=25 millimeter.
Because the combination of noise reduction cellular board, support framework and buoyancy body is placed in the pond of cooling tower, distance between the lower surface of noise reduction cellular board and the pond water surface is a steady state value, thereby can effectively control the secondary noise that falls into water through behind the noise reduction cellular board, its noise reduction is stable; Because the planform of noise reduction cellular board is improved, be provided with curved surface power consumption pipe in the lower end of inclined-plane hush tube simultaneously, it can further consume drowning energy, thereby reduces the drowning noise of cooling tower to greatest extent.
Cooling tower is when work, hot water in central authorities' vertical shaft flows in the distribution channel, from spray equipment, fall, drip downwards by packing, produce the mechanism of noise according to falling into water, reduce drowning noise, must manage to destroy the formation condition of drowning noise, on the water surface of pond, set up the float-type drop denoising device, avoid falling into water and directly impact the pond water surface, can not only change the landing shock character of falling into water, adopt segmentation, multistage energy-eliminating noise-reducing principle is landed successively in the inclined-plane of noise reduction cellular board hush tube water droplet in dropping process, making falls into water produces noiseless water conservancy diversion, wipe and paste, be detained, choose stream through the multistage power consumption of curved surface energy dissipating pipe again, evacuate, reach the purpose that reduces the noise that falls into water.The noise reduction cellular board is placed in the pond of cooling tower by support framework, tubulose buoyancy body, can guarantees the distance of the noise reduction cellular board and the water surface, can prevent effectively that the secondary noise that falls into water from producing, thereby stablize the noise reduction of whole cooling tower.
