Abstract

The invention relates to a hyperbolic cooling tower water spray noise abatement and thermal insulation system applied to the cold region in the northern part of China. The hyperbolic cooling tower water spray noise abatement and thermal insulation system is composed of a noise absorption and insulation roof, double-sided noise absorption pieces, a piece support and a regulator, wherein a noise abatement material is customized according to a water spray noise frequency spectrum and fixed by keels; noise abatement blades are parallelogram streamline bodies, are composed of a low and medium frequency noise absorption layer, a noise insulation layer and a high frequency noise absorption layer, include adjustable noise absorption pieces and fixed noise absorption pieces, and are fixed by a support. According to the invention, the size of an air inlet is adjusted according temperature, so that air inlet volume is reasonable, and the noise can be effectively reduced. During reversal of seasons, a user can close and open the double-sided noise absorption pieces on the ground, so that cooling water has small possibility of freezing; the hyperbolic cooling tower water spray noise abatement and thermal insulation system is suitable for both northern areas and southern areas of China. A thermal insulation system is composed of a fixed thermal insulation board, an adjustable thermal insulation board, an adjustable thermal insulation board rotating shaft, an adjustable thermal insulation board bracket and a thermal insulation regulator, and the air inlet volume can be regulated according the temperature.

Description

Hyperbolic cooling tower trickle noise is administered and heat-insulation system
Technical field
The present invention relates to and a kind of on double-curve cooling column, play sound deadening and can according to the continuously adjustable intelligent noise reduction heat-insulation system of temperature height.
Background technology
At present, some Industrial cooling towers such as power plant, chemical plant allow because of place, and adopt hyperbola energy-saving cooling tower, its trickle noise figure is higher, and a part can not meet environmental requirement, impact the life of factory's surrounding resident and this enterprise safety operation; Simultaneously at cold district, winter, cooling tower trickle easily froze, and produces bring serious inconvenience to enterprise.The present invention is the silene system that will provide a kind of improvement, can noise reduction can be incubated again, can make noise figure meet the requirement of environmental protection opening in situation, can play insulation effect again, and flowing resistance is very little when closing.
Summary of the invention
The technical solution used in the present invention is: the air inlet of tower body " seals " by sound absorption and insulation top board (having insulation and sound absorption function) and adjustable insulation sound absorption and insulation system.Adjustable sound absorption and insulation plate is in closed state in the winter time, at this moment whole system is by being incubated and sound insulation effect, along with the rising of temperature, adjustable sound absorption and insulation plate is made adjustment, can ensure that water does not freeze, can ensure ventilation and heat again, and ventilating system has silencing function, sound absorption and insulation plate adjusting angle is at 0 °--within the scope of 45 °.Do not needing in noise reduction situation, fixed sound absorption and insulation plate can be removed, change adjustable two-sided sound absorption and insulation plate into adjustable warming plate, according to variations in temperature, adjustable warming plate makes angle adjustment, both ensured that water did not freeze, ensure again to produce reverberation, the angle of adjustment is at 0 °--within the scope of 45 °.

accompanying drawing illustrates:
Specific embodiments: the structure of silene system of the present invention is: the air inlet of double-curve cooling column " seals " (as shown in Figure 1) by silene system 2 and sound absorption and insulation top 1.At cold district, winter, the cooling water of cooling tower easily froze, and this silene system will play insulation effect; In summer, this system will ensure to ventilate, and ensures cooling tower operating efficiency, and will have sound deadening, ensures that Showering water sound factory circle is up to standard, along with adjustable two-sided sound absorption and insulation plate 6 is adjusted angle (0 °--45 ° of scopes) by support 3 and adjuster 7 by the change of temperature.Fixed double-sided sound absorption and insulation plate 5 keeps motionless, like this, the ventilation muffler that 5 and 6 formation one are large, for preventing 5,6 leakage sound, in the middle of two absorbent treatments 10,12, add one deck sound insulating layer 11, can effective shadow zone be formed, during adjustment, will angular dimension be noted, should ventilation and heat be ensured, ensure that water does not freeze again.When winter is the coldest, 6 is totally-enclosed, (as shown in Figure 2), and when summer is the hottest, 6 open (as shown in Figure 3) entirely, the Showering water sound of such double-curve cooling column after silene system 2 processes audio spectrum close to noisc rating number.In the part of cooling tower without the need to noise reduction, removed by fixed head 5, adjustable two-sided sound absorption and insulation plate 6 changes adjustable warming plate 14 into.14 have two-layer (as shown in Figure 8), and one deck absorbent treatment 19, prevents reverberation; Another layer of tolerant noise-insulating warm-keeping layer 20, has insulation and sound insulation effect.According to variations in temperature, by adjustable heat-insulation support 16 and adjustable insulation turning cylinder 15, insulation adjuster 17, adjustable warming plate 14 is regulated (as shown in Figure 9), ventilation and heat should be ensured, ensure that again water does not freeze, be adjusted to closed condition (shown in Fig. 6) when temperature is minimum, complete opening (as shown in Figure 7) during the highest temperature, can ensure not produce reverberation like this, the ventilation and heat of cooling tower can be ensured again, substantially constant before the operating efficiency of tower and process.
