Description

Noise eliminating and anti-freezing device of cooling tower
Technical field
The present invention relates to the cooling tower noise absorber, is a kind of noise eliminating and anti-freezing device of cooling tower.
Background technology
The noise that cooling tower produces when water cooling is higher, and particularly the noise of large cooling column generation has a strong impact on neighboring area people's normal life and working environment.Therefore, those skilled in the art have designed multiple scheme and have been abated the noise.The silencing apparatus that generally uses mainly is to build steel structure frame at the peripheral tower of cooling tower at present, and abatvoix is installed on framework.The deficiency of this structure is, the noise elimination effect that abates the noise and only depend on sound-absorbing material itself, and the ventilation between abatvoix can't be regulated, and therefore, the effect that abates the noise is relatively poor, and erasure effect and ventilation can't reach better state simultaneously.In addition, at present, these cooling tower silencing apparatus all can not solve the problem that cooling tower freezes.
Summary of the invention
The objective of the invention is, a kind of noise eliminating and anti-freezing device of cooling tower is provided, it can effectively solve the problem of the noise nuisance people operate as normal life of cooling tower, significantly reduces noise, and can effectively prevent the problem that cooling tower freezes.
The present invention for achieving the above object, be achieved through the following technical solutions: noise eliminating and anti-freezing device of cooling tower, comprise several columns and crossbeam, between per two columns cross supporting frame is set, the several piece anechoic sheet is installed on the cross supporting frame, between per two anechoic sheets ventilating duct is set, each anechoic sheet one end is all installed a deflector, between deflector and the anechoic sheet inclined angle alpha is set, deflector and anechoic sheet are hinged, deflector one side two ends is hinged with first connecting rod and second connecting rod respectively, first connecting rod and first drive rod, one end are hinged, the first drive rod other end and head rod one end are hinged, first drive rod is connected with anechoic sheet by first rotating shaft, the head rod other end and first swingle, one end are hinged, the first swingle other end is connected with the adjusting rotating shaft, second connecting rod and second drive rod, one end are hinged, the second drive rod other end and second connecting rod, one end are hinged, second drive rod is connected with anechoic sheet by second rotating shaft, the second connecting rod other end and second swingle, one end are hinged, the second swingle other end is connected with the adjusting rotating shaft, regulates in the rotating shaft regulating handle is installed.The end of regulating rotating shaft place is installed on anechoic sheet dial is installed.Deflector is installed on first framework, and deflector is rectangular, and first framework, one end is connected with anechoic sheet with second axle sleeve by first axle sleeve, and first axle sleeve and second axle sleeve are installed in side two ends of anechoic sheet respectively.Inclined angle alpha between deflector and the anechoic sheet is the 40-60 degree.
The invention has the advantages that: because structure such as deflector is set, it can increase substantially the noise elimination effect of cooling tower, straight shape air-flow by anechoic sheet changes bending shape air-flow into, changed the direction of air-flow, make sound wave repeatedly bending in anechoic sheet, strengthened the incidence angle of sound wave to sound-absorbing material, the noise elimination effect improves about 30% than prior art, and can realize the antifreeze of cooling tower simultaneously, particularly can adjust the angle of the deflector of the silencing apparatus that is installed in the large cooling column periphery very easily with respect to anechoic sheet, at any time regulate intake, make noise elimination effect and intake remain on better level simultaneously; When environment temperature is low, deflector is turned an angle, partly or entirely close the ventilating duct between the anechoic sheet, reduce the ventilation of cooling tower, improve the temperature of cooling water, the pond temperature is remained on more than 0 ℃, prevent that effectively cooling tower from freezing.The deflector structure of setting of the present invention is equivalent to be provided with in noise elimination place outlet the sudden expansion pipe of certain corner, reduced the resistance to flow output of silencing apparatus, the flowing resistance of whole silencing apparatus is reduced, the ventilation of silencing apparatus has improved 15% than prior art, has improved the cooling effect in summer of cooling tower greatly.The present invention also has the low advantage of cost, because the present invention has adopted structures such as deflector, can also reduce the length of anechoic sheet when significantly improving erasure effect, thereby reduces manufacturing cost etc.
