The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in detail.
As shown in Fig. 1 a, 1b, for cooling tower anti-wall flow shower nozzle, by nozzle body and two parts of fixed muffle, formed.Nozzle body comprises water inlet 1, Fixed latches 3, conical central guiding circulation road 2, shower nozzle back water fender 4, ground floor splash board 5,7, the four layers of splash board 8 of 6, the three layers of splash board of second layer splash board, edge sawtooth 9.
As Fig. 4 a, shown in 4b, fixed muffle comprises the connecting port 13 connecting with water distribution subtube, handle 10, pilot pin groove 11, fixing hole 12.
Fixed muffle is cylindric, overall length 45 ~ 60mm, is divided into upper and lower two parts, and the first half is long is L, it is relevant that its length L and water distribution are in charge of caliber, by formula (1), calculated, its wall thickness 2 ~ 3mm, adopts PUR hot melting way to be connected with water distribution subtube, long 25 ~ the 35mm of the latter half, internal diameter is 33.4mm, and wall thickness 2 ~ 3mm, with latch groove 11 and fixing hole 12.
（1）
In formula: D
1the external diameter of-water distribution subtube;
D-sleeve the first half external diameter;
Nozzle body water inlet 1 external diameter 33.4mm, wall thickness 2 ~ 3mm, has Fixed latches 3(Fig. 3 on it), after it coordinates with latch groove 11 and fixing hole 12, the position of shower nozzle and towards just fixing.
Nozzle body from position of center line in two, half part has four layers of semicircle splash board (Fig. 5 a, 5b), water is come by these four layers of splash boards spilling in layer, second half part is middle shower nozzle back water fender 4(Fig. 2 a with half cone-shaped flow-guiding channel, 2b), shower nozzle back water fender 4 and four layers of splash board fit in the nozzle body of center circle taper through hole.
First splash board that shower water runs in the process falling is ground floor splash board 5, sequence successively, ground floor splash board 5 diameter 80 ~ 100mm, diameter 20 ~ the 22mm of central through hole, it is 25 ~ 35mm to the vertical range of delivery port, and ground floor splash board 5 distributes the water yield to account for 50% of shower nozzle total Water.
Second layer splash board 6 diameter 50 ~ 60mm, central through hole diameter 13 ~ 15mm, it is 25 ~ 35mm to the vertical range of ground floor splash board 5, second layer splash board 6 distributes the water yield to account for 25% of shower nozzle total Water.
The 3rd layer of splash board 7 diameter 20 ~ 25mm, central through hole diameter 5 ~ 7mm, it is 25 ~ 35mm to the vertical range of second layer splash board 6, the 3rd layer of splash board 7 distributes the water yield to account for 20% of shower nozzle total Water.
The 4th layer of splash board 8 diameter 3 ~ 5mm, center is without through hole, and it is 10 ~ 15mm to the vertical range of the 3rd layer of splash board 7, and the 4th layer of splash board 8 distributes the water yield to account for 5% of shower nozzle total Water.
High in the middle of splash board, edge is low, and the angle that the formation gradient is α, increases gradually from four layers of splash board angle of gradient of ground floor to the, and α generally gets 10 ~ 30 °.
Splash board edge is zigzag, and sawtooth tooth depth is 3 ~ 6mm, and the central angle that sawtooth is corresponding is β, and according to the size of each different layers splash board, central angle value is different, and the central angle between Dan Liangchi center is always 2 β.
Following examples be take squarer as example.
During installation, fixed muffle is arranged on water distribution subtube, and the fixing hole of fixed muffle is parallel towards the cooling tower wall with closing on, and can guarantee that so whole semicircles region of anti-wall flow shower nozzle sprinkling is all on filler.
As shown in Figure 6, in total region C of sprinkling, shower nozzle adopts center staggered form to arrange, the spray region external diameter of a shower nozzle is crossed the center of circle in adjacent shower nozzle spray region, arranges conventional shower nozzle 20 in dashed region.The diameter that single conventional shower nozzle sprays region A is D
1, anti-wall flow shower nozzle 21 is 1.1 ~ 1.2D with closing on conventional shower nozzle 20 distances
1, in the time of can guaranteeing that like this water spray fluctuates in design discharge certain limit, conventional shower nozzle 20 shower waters yet can not spray on wall and go, and effectively prevent the generation of wall stream.Anti-wall flow shower nozzle 21 be arranged on filler edge directly over, the diameter of its sprinkling region B is 1.1 ~ 1.2D
1.Anti-wall flow shower nozzle 21 has identical spray flux with conventional shower nozzle 20, and the conical flow-guiding channel of nozzle body back baffle plate plays guide functions, as shown in Figure 2 b.When shower water is with flow velocity V
1under vertical current, under the effect of circular cone flow-guiding channel, V
1can be gradually increase, a part of water and ground floor splash board generation inelastic collision in the process that continues to fall, because splash board has certain gradient, generation be oblique impact, according to non-resilient oblique impact principle, the conservation of momentum, shower water horizontal velocity V=V
1, shower water leave the horizontal flow velocity V of splash board can be larger than conventional shower nozzle, by the known sprinkling regional diameter of formula (2) D
2larger.
（2）
In formula: the speed in V-shower water horizontal direction;
H-splash board is to the vertical range of filler;
G-acceleration of gravity;
After shower water is caught by ground floor splash board, with horizontal velocity V, along splash board edge, spread out uniformly, shower water has a viscous force part trickle is produced to inhibition when leaving jagged edges, and this part current degree can reduce, from (2) formula, spray regional diameter D
2reduce, thereby make trickle reach better dispersion effect.
Second and third, splash board and the ground floor of four layers produce same effect, shower water is caught by splash board in layer in the process falling, by this layer of splash board, disperseed again, shower water is sprayed in spraying region more even, improve the cooling capacity of cooling tower.
The utility model adopts Fixed latches and latch groove, fixing hole to coordinate, guaranteed shower nozzle fixing towards time, install and change more simple and convenient.
The utility model is applicable to the cooling tower of tubular type water distribution, and nozzle body adopts glass fiber enhanced nylon material, high temperature resistant, not yielding, can guarantee uniformity and the stability of spraying.
