Abstract
In the falling water noise reducing plate for cooling tower, each silencing pipe includes successively connected five sections, one vertical section, one first inclining section, one second inclining section, one turning reflux section and one stretching curve section. The vertical section in the upper part can guide falling water without noise; the two inclining sections in the middle part can silence water falling through slant friction and reduce water flow speed; and the turning reflux section and the stretching curve section in the lower part can dissipate the energy of falling water and further lower the noise of falling water by means of pores and corrugated grooves and sound wave interference. The present invention has ideal noise reducing effect.
Description
Technical field
The present invention relates to the cooling tower falling water noise reducing device that the power plant uses, relate in particular to cooling tower falling water noise reducing plate.
Background technology
At present, the cooling tower falling water noise reducing device that the power plant uses, what noise reduction was best is exactly " the cooling tower falling water noise reducing device " of the applicant in the calendar year 2001 application, the patent No. is 01230431.X, it is the cellular noise reducing plate of the pipe oblique arrangement formation of both ends open, 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, this falling water noise reducing device has become the first-selected articles for use that current power plant cooling tower noise reduction is transformed, it has represented the highest level of current noise reduction product, but also have certain defective in actual use, cellular noise reducing plate is reasonable not enough at product structure, lacks drop energy-eliminating and secondary denoising structure, the secondary noise that is produced is also bigger, fails to fall to greatest extent back noise.
Summary of the invention
Goal of the invention of the present invention provides a kind of secondary cooling tower falling water and falls plate, and it can effectively reduce the secondary noise, makes the falling water noise reducing device have better noise reduction.
The technical solution used in the present invention is:
Plate falls in described secondary cooling tower falling water, the cellular flaggy that it is combined by some moulding plastics plates, on cellular flaggy, be formed uniformly some hush tubes, it is characterized in that: every hush tube is provided with vertical section from top to bottom successively, the chopped-off head tilting section, the secondary tilting section, turn to reflux section and choose the stream curved sections, at the chopped-off head tilting section, the secondary tilting section is equipped with micropore with turning on the reflux section, at the secondary tilting section, turn to reflux section to be provided with wave groove, in every wave groove, all be provided with micropore, be arranged on its front at wave groove on the secondary tilting section, wave groove is arranged on its reverse side on the reflux section turning to.
The diameter of described micropore is 0.5～3.0 millimeter; Chopped-off head tilting section, secondary tilting section, turn to reflux section and the angle chosen between stream curved sections and the horizontal line is respectively 70 °～80 °, 45 °～70 °, 105 °～120 °, 125 °～150 °.
Because will every hush tube have designed vertical section, chopped-off head tilting section, secondary tilting section, reverse reflux section from top to bottom successively and chosen the stream curved sections, top is straight length, is the water inlet of straight hole shape, it can make the noiseless water conservancy diversion of generation that falls into water; The middle part is the tilting pipe of eighty percent discount, it divides chopped-off head tilting section, secondary tilting section two parts, it can make water droplet produce to wipe by the inclined-plane and paste the noise elimination effect, the micropore that distributes simultaneously thereon can form the delay moisture film on chopped-off head tilting section, secondary tilting section, making falls into water cushions land with being detained moisture film, can further reduce the impulsive sound that falls into water to the inclined-plane; On the secondary tilting section, wave groove is set, makes it to possess the energy dissipating decelerating effect; The stream pipe is chosen for the eighty percent discount energy dissipating in the bottom, and it is divided into the reverse reflux section and chooses the stream curved sections, and the reverse reflux section is reverse tilting noise reduction section, on this section, not only be provided with micropore but also be provided with wave groove, except reducing the secondary noise, can also utilize the principle of interference of sound wave, reduce tube noise intensity; Choosing the stream curved sections can guide current smoothly to import the pond, this three ones five sections denoising structure, noise elimination is pasted in generation water conservancy diversion, inclined-plane wiping in pipe, moisture film is detained and the wave groove energy dissipating to make water droplet, reverse flip trajectory bucket noise reduction, the reverse interference noise reducing effect of sound source, thus make the present invention have better noise reduction.
