Abstract
When the utility model provides a kind of water distribution without umbrella, without hollow, water spray evenly, good antiscale property stops up, to improve the water-distribution nozzle of cooling tower cooling effect.It comprises a main body tube and two discs, and middle disc has a main body panel and is evenly distributed on the gear blade of main body panel periphery, and the centre of main body panel has pod apertures, and coaxial in main body tube; Bottom disc is square main body panel, on disk body and be uniformly distributed from the radioactive notch of central point, increases cloth water area.These two kinds of main body panels combine and make water distribution water (flow) direction is variable, can make water distribution head stop up.
Description
Technical field
The utility model relates to the tubular type water-distribution nozzle for closed cooling tower
Background technology
The tubular type water-distribution nozzle that closed cooling tower uses at present generally comprises a main body tube and is arranged on a flat splash box of main body tube below, water-distribution nozzle is the important core part in closed cooling tower tower core components, the height of the thermal performance efficiency of cooling tower has significant relationship with the performance of water-distribution nozzle water spray, and cloth water distribution quality directly affects the thermal performance of cooling tower.
But present water-distribution nozzle splash box plane is entity, can produce obvious umbrella when water distribution, and hollow area is larger, and the globule is not of uniform size, and water distribution is inhomogeneous, and the easily fouling of splash box surface, cooling tower thermal performance affected.
Utility model content
The purpose of this utility model is can produce obvious umbrella while solving conventional water-distribution nozzle water distribution, hollow area is larger, the globule is not of uniform size, and water distribution is inhomogeneous, and the easily anti-blocking efficient cooling tower water-distribution nozzle of the novel closed cooling tower of fouling of splash box surface.
This water-distribution nozzle for cooling tower, comprise a main body tube and two discs, it is characterized in that it comprises that the disc of two different structures, middle disc have a main body panel and be evenly distributed on the gear blade of main body panel periphery, the centre of main body panel has pod apertures, and coaxial in main body tube; Bottom disc is square main body panel, on disk body and be uniformly distributed from the radioactive hydrophobic gap of central point notch, increases cloth water area.These two kinds of main body panels combine and make water distribution water (flow) direction is that rotation is variable, can make water distribution head surface be not easy to stop up.
This water-distribution nozzle is called the two-layer vane type disc of tubular type atomizing nozzle, its beneficial effect is: water flows down in main body tube, disc in the middle of being first flushed to, part current flow downward through the pod apertures of middle disc, and through the gear blade of middle disc, the hydrophobic gap right-spiral between gear blade flows downward a part of current.The water flowing down in pod apertures splashes on the square disc in bottom, flows downward from the hydrophobic gap of radioactivity.The utility model is due to the size relationship of upper and lower two disc water distribution manner different characteristics, and adjacent two discs up and down that make have complementarity in radial direction, uses without umbrella, and without hollow, water spray evenly, prevents fouling, has ensured the cooling effect of cooling tower.
Above-mentioned water-distribution nozzle, sees from top to bottom, and each blade becomes dextrorotation to be arranged on middle disc.The blade that dextrorotation is arranged makes the current that flow from the top down have dextrorotation phenomenon, can effectively prevent the generation of umbrella.
Above-mentioned water-distribution nozzle, middle disc is high in the middle of being, and the taper that periphery is low makes current on disc can flow to smoothly the periphery of disc gear blade.
Above-mentioned water-distribution nozzle, the outer contour of middle disc gear blade is smooth transition curve, with make water distribution more continuously, evenly, radioactivity gap water distribution on the square disc of water that flows down of pod apertures, make water distribution without hollow phenomenon.
Above-mentioned water-distribution nozzle, gear dextrorotation changes water distribution direction makes unsuitable fouling on disc.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, the anti-blocking efficient cooling tower water distribution fountain head of one described in the utility model, can be described as the two-layer vane type disc of the tubular type water-distribution nozzle that dabbles.This shower nozzle comprise main body tube 1, rubber dop 2, middle disc 4, two main body tubes in the middle of 5 and 1 of middle disc dowel 3, bottom disc disc in bottom disc dowel 5.The outer rubber card head that is provided with of main body tube 1 is connected to supervisor above, convenient with changing.
Middle disc has a main body panel 7 and equally distributed gear blade 8, and the outer contour of blade is smooth transition curve, sees from top to bottom, and 8 one-tenth dextrorotation of blade are arranged on main body panel.Blade is provided with hydrophobic gap between blade, ensures that water distribution is even.The central part of main body panel has pod apertures.Pod apertures is large equirotal straight hole up and down, high in the middle of disc is, the taper that periphery is low.Two discs are positioned at the card below of main body tube 1, and pod apertures is coaxial in main body tube.Two dowels 3 couple together main body tube in middle disc, dowel 5 couples together two discs, main body tube are connected as a whole in two discs, injection molded with high-quality engineering plastics, meet completely under high temperature, cold working condition and use.
Water has the main body tube at shower nozzle top to enter, and accelerates vertical drop to disc through head natural gravity.Advantage of the present utility model is:
1. water spray angle is large;
2. water droplet is tiny, without umbrella;
3. water distribution is even, without hollow phenomenon;
4. pressure of supply water is low;
5. should not stop up;
6, sturdy and durable;
7. it is convenient to change, and does not need maintenance.
