Abstract
The utility model relates to a nozzle for cooling towers, which is a water distribution component in a cooling water tower. The utility model is composed of a nozzle housing 1, an inner core section 2, a mixing section 3 and a nozzle section 4, wherein, the nozzle housing 1 is connected with the upper connection tube of the nozzle of a cylinder filleting section 5 by threads, and the inner core section 2 is provided with a medium column-shaped flow channel 8 and four incline-shaped flow channels 9, 10, 11 and 12. After through the inner core section 2, cooling water can be split into a columnar flow and four strands of rotary ambient flow so as to be intensely mixed in the mixing section 3, and the cooling water can flow from a nozzle outlet 6. The utility model has the characteristics of low water supply pressure, low sprinkling height, uniform water distribution, low cost, high yield and stable quality. The utility model can be used in round and square counter current towers.
Description
The cooling tower nozzle is the parts of water distribution in the cooling tower.
The uniformity of water distribution in the cooling tower will directly have influence on the cooling-down effect of cooling tower, and the energy consumption that also directly has influence on water distribution system falls in the pressure of water distribution system.The contrast prior art, garden shape countercurrent tower nearly all adopts the turning spurt water device water distribution, and turning spurt water device in a single day malfunctioning after, the water distribution meeting in the cooling tower is extremely inhomogeneous, has a strong impact on cooling effect; The square countercurrent tower adopts single swirl nozzle water distribution or the water distribution of reflection II type nozzle mostly, adopt single swirl nozzle water distribution, exist hydraulic pressure requirement height, the injection angle of flare is little, the inhomogeneous and susceptible to plugging disadvantage of water distribution, and reflection II type nozzle water droplet distributes also very uneven, and it is less than normal to spray angle of flare, require spray highly high, but this can cause the increase of tower total height, and the cooling tower cost is increased.
In order to overcome the shortcoming of turning spurt water device water distribution and single swirl nozzle water distribution in the prior art, the water distribution of reflection II type nozzle, the purpose of the present utility model is the low-pressure nozzle that a kind of jet expansion angle of flare of design is big, water droplet is evenly distributed.
Nozzle of the present utility model is by nozzle body, the inner core section, blending section and spout section are formed, nozzle body and nozzle upper connecting tube are with being threaded, nozzle links to each other with sparge pipe by upper connecting tube, there is one section garden cylindricality rectification section in nozzle upper connecting tube import department, and four oblique runners and an intermediate cylindrical runner are arranged on the inner core section, all is made into the garden arc before and after jet expansion.

Fig. 4 is an inner core section runner A-A cutaway view
1 is nozzle body among the figure, the 2nd, and the inner core section, the 3rd, the blending section, the 4th, the spout section, the 5th, rectification section, the 6th, jet expansion, the 7th, nozzle inlet, the 8th, the cylindricality runner, 9,10,11,12 is 4 oblique runners, the 13rd, internal thread, the 14th, external screw thread.
The concrete enforcement of the utility model nozzle is: nozzle body is by nozzle body 1, inner core section 2, blending section 3, spout section 4 is formed, nozzle body is connected with nozzle upper connecting tube internal thread 13 by the external screw thread on the nozzle body 1 14, nozzle body links to each other with sparge pipe by the nozzle upper connecting tube, and it is L that there is a segment length in nozzle upper connecting tube import department
1Garden tubular rectification section 5, the internal diameter of rectification section 5 is identical with nozzle inlet 7 inside diameter D, the length L of rectification section 5
1=D can make cooling water pass through nozzle inlet 7 like this and evenly flow into inner core sections 2, and the center cylindricality runner 8 through inner core section 2 in and four oblique runners 9,10,11,12 are divided into columnar flow and the length L of inner core section 2 is streamed in four bursts of rotations on every side then
2Jet expansion 6 inner diameter d
2Cooling water flow out of to make after the inner core section 2 and stream and columnar flow is carried out fierce blending, the length L of blending section 3 in blending section 3
3=1.5L
2～1.8L
2The length of spout section 4 is L
4, all make the garden arc in the front and back of jet expansion 6, make liquid stream after the blending with lower drag losses mass flowing nozzle outlet 6, to improve the flow velocity and the flow of water, further the particle diameter of refinement water droplet improves the water droplet angle of flare.Jet expansion 6 areas/nozzle inlet 7 areas=d
2 2/ D
2 2=0.15 ± 0.05.The aperture d of center column runner 8 in the inner core section 2
1Be 15% ± 5% of nozzle inlet inside diameter D; The inclination angle ψ of oblique runner 9,10,11,12 is 45 ° ± 5 °.
Nozzle body ABS plastic single injection-molded, nozzle upper connecting tube PVC plastic production so that with PVC sparge pipe plastic welding.
The utility model nozzle pressure of supply water is low, only needs 0.2～0.4kgf/cm2, can save pump energy consumption, and general nozzle needs 1kgf/cm2Pressure, the spray height of nozzle is only about 0.4M, can reduce the tower body height of cooling tower, can save tower body cost 5～10%, this nozzle water distribution uniformity is better than single eddy flow and reflection II type nozzle, actual measurement cooling value △ t can improve more than 0.3 ℃, and performance of anti-blockage also is better than turning spurt water device and single swirl nozzle. The nozzle body single injection-molded, the characteristics such as it is low to have a cost, and the output high-quality is stable can be widely used in garden shape and the square countercurrent tower.
