Abstract
The utility model relates to an improvement on a water spraying nozzle for a cooling tower. The water spraying nozzle is characterized in that a hollow nozzle body adopts a vertically adjustable structure which at least comprises two sections; and a built-in spraying core adopts a crossed-twisting blade, the twisting angle of which ranges from 45 to 60 DEG. The water spraying condition is greatly improved, the thinner atomization effects of water drops are better, the mist spraying range is large, the heat exchange contact area between cooling water and air is increased obviously, and the cooling effect is improved. The vertically adjustable structure also enables the water spraying range of the nozzle to be changed according to the location space, and further improves the flexibility of nozzle application; therefore the nozzle is especially applicable to the improvement of the conventional cooling tower.
Description
Technical field
Utility model is about the improvement to the cooling tower sprinkler head, relates in particular to a kind of used for cooling tower trickle shower nozzle.
Background technology
The cooling tower shower nozzle is mainly used in counterflow cooling tower, need cooling water forms vaporific drop by shower nozzle and sends forth, enlarges to send area forth and form water smoke to drip, thereby improves the cooling water heat exchange area, satisfies the heat exchange requirement.The spraying drop size of the quality of counter-flow cooling tower cooling effect and shower nozzle, area have direct relation, and it is determining the cooling effect of counter-flow cooling tower.Prior art counterflow cooling tower sprinkler head, a kind of more employing three splashing type shower nozzle (Fig. 1), its spraying principle is, press water scatters and shower nozzle inwall collision sputter by three layers of splash box 1.1,1.2,1.3 up and down step by step, makes water form vaporific little water droplet.Yet simply still bigger than normal by the disc type sputter water droplet that mode forms that scatters, it is also big inadequately to send area forth, and a common shower nozzle is apart from the maximum at the below 500mm place area 0.3m that scatters
2, and non-adjustable once making, can not realize requiring to change the water spray situation according to cooling.
Above-mentioned deficiency still has is worth improved place.
The utility model content
The utility model purpose is to overcome above-mentioned the deficiencies in the prior art, provides a kind of water spray water droplet littler, and it is bigger to send area forth, and sends the adjustable used for cooling tower sprinkler head of area forth.
The utility model purpose realizes, it is main that to improve one be to be vertical adjustable structure with hollow shower nozzle structural reform, the 2nd, change splash box in the shower nozzle into the cross twisted blade, its twist angle is the 45-60 degree, vertically regulates by sprayer body, and change is sprayed water and amassed, the crosswise blade inner core, can make water droplet be vaporific, thereby overcome the deficiencies in the prior art, realize the utility model purpose.Specifically, utility model used for cooling tower sprinkler head comprises the hollow sprayer body, and built-in spray core, it is characterized in that the hollow sprayer body forms vertically adjustablely by at least two sections, and built-in spray core is that twist angle is the cross twisted blade of 45-60 degree.
Utility model is said:
The used for cooling tower sprinkler head, main effect is vertically adjustable by at least two sections compositions of sprayer body, is used to regulate shower nozzle and sprays row's degree, reaches to change the spraying area, installs to adapt to different distance.Vertically adjustable a kind of better be to adopt to be threaded, the location after helping regulating, other form is axially adjustable certainly, neither.
Twist angle is the cross twisted blade inner core of 45-60 degree, the press water that enters shower nozzle can be become vaporific ejection by this inner core, thereby forms thinner vaporific water droplet, has increased aqueous vapor heat exchange contact area, has improved cooling effect.
Utility model used for cooling tower sprinkler head, with respect to prior art, owing to spray is changed into vertically adjustable, and twist angle is the cross twisted blade of 45-60 degree, thereby greatly improved the water spray situation, not only more mistization is effective for water droplet, and the spraying area is big, for example equally can reach 1.0m apart from the maximum at the below 500mm place area that scatters
2, significantly increased the contact heat exchange area of cooling water with air, improved cold effect.Vertically adjustable structure also makes single shower nozzle trickle area to change according to placement space, has improved the shower nozzle application flexibility especially, is specially adapted to the transformation of existing cooling tower.
Below in conjunction with an exemplary embodiment; utility model essence is further understood in exemplary illustration and help; but the embodiment detail only is for utility model is described; do not represent utility model design whole technical schemes down; therefore should not be construed as the total technical scheme of utility model is limited; some are In the view of the technical staff; the unsubstantiality that does not depart from the utility model design increases and/or change; for example change or replace, all truely use novel protected scope so that technical characterictic with same or similar technique effect is simple.

The specific embodiment
Embodiment: referring to Fig. 2-4, utility model used for cooling tower sprinkler head comprises the straight tubular sprayer body 2 of hollow, and built-in twist angle is the cross twisted blade 3 of 60 degree, below outlet 4.The hollow sprayer body is spirally connected by top 2.1 and bottom 2.2 and forms, and adjusts axial distance by spiral and changes the spraying area, and cross twisted blade 3 is arranged in the top sprayer body 2.1.
To those skilled in the art; under this patent design and specific embodiment enlightenment; some distortion that can directly derive or associate from this patent disclosure and general knowledge; those of ordinary skills will recognize also can adopt additive method; or the substituting of known technology commonly used in the prior art; and the equivalence of feature changes or modification; mutual various combination between feature, for example variation of twisted blade angle, shower nozzle diameter variation; the vertically variation of regulative mode; or the like unsubstantiality change, can be employed equally, can both realize this patent representation function and effect; launch for example no longer one by one to describe in detail, all belong to this patent protection domain.
