Background technology
Cooling tower is as a kind of device of getting rid of used heat, be widely used in the industrial production and central air conditioning equipment in, no matter freeze or heat supply will produce a large amount of useless used heat, the cooling tower that often adopts various types with this part waste heat discharge in atmosphere.Adopt packless cooling tower can avoid fouling, aging and secondary pollution problems, the atomizer of cooling tower without filling material employing at present exists the big and uneven characteristics of water distribution of atomizing particle size, also exist and utilize higher operating pressure at sprinkler, usually〉0.1MPa, realize than the small particle diameter and the better uniformity, improved the operating pressure of shower nozzle, increased the energy consumption of cooling tower accordingly, and in the transformation of old-fashioned cooling tower, may relate to the replacing of pump equipment in addition, increase the difficulty of technological transformation.
Existing atomizer, usually the centrifugal principle that adopts will be intake by nozzle and the mixed atomizing of air, and the shortcoming of this class shower nozzle is that the diameter of injection droplet is very high with the pressure head correlation that enters shower nozzle, bigger than normal at system's mist droplet particle size that hydraulic pressure is on the low side, influenced the heat and mass of hot water.Simultaneously, be easy to generate wall stream at small-sized tower because the injection angle of flare of nozzle is big and have the hollow phenomenon.
Summary of the invention
The purpose of this utility model provides the swirling flow air inducing atomizer that the hollow water spray is evenly avoided in a kind of small particle diameter atomizing.
For realizing above purpose, the technical solution of the utility model provides a kind of swirling flow air inducing atomizer, it is characterized in that, by swirling flow water inlet pipe, swirling flow chamber, swirling flow contraction chamber, convergent jet pipe, jet expansion, divergent nozzle, nozzle air inducing hole with hide water along forming, swirling flow water inlet pipe internal diameter and swirling flow chamber internal diameter are tangent, top, swirling flow chamber is connected with the swirling flow contraction chamber, the swirling flow contraction chamber links to each other with the atomizer that convergent jet pipe and divergent nozzle are formed, divergent nozzle is connected with jet expansion, is provided with nozzle air inducing hole around the jet expansion and hides the water edge.
The utility model makes water rotate by the swirling flow water inlet pipe, and by the atomizing of convergent divergent nozzle, it is less that this swirling flow air inducing atomizer has atomizing particle size, equivalent particle size＜1.0mm, operating pressure is low, be 0.05MPa, flow does not evenly have the characteristics of hollow water spray, under the low import water pressure condition of 0.05MPa, by convergent the divergent nozzle less and even water droplet of particle diameter that atomizes out, further mend air atomizing through the nozzle air-vent, with heat and mass transfer enhancement, and continue to use diffusion angle and the trickle uniformity that atomizes with the control jet pipe by the screening water around the jet expansion, alleviated the hollow problem of other atomizer.
The utility model has the advantages that can obtain enough little water droplets and water distribution uniformity is preferably arranged that single swirling flow air inducing atomizer is when design pressure of supply water 0.06MPa, the water yield can reach 0.8-3.2t/h, and has good atomizing effect.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, 2, be a kind of swirling flow air inducing atomizer structure schematic diagram, described a kind of swirling flow air inducing atomizer is made up of along 8 swirling flow water inlet pipe 1, swirling flow chamber 2, swirling flow contraction chamber 3, convergent jet pipe 4, jet expansion 5, divergent nozzle 6, nozzle air inducing hole 7 and screening water.
Described water inlet pipe 1 is the swirling flow water inlet pipe, with the outside, coupling part of water main for being threaded, the water inlet internal diameter simultaneously with swirling flow chamber 2 in circle, 2 bottom surfaces, swirling flow chamber while tangent, its diameter range is 7mm-25mm; Swirling flow chamber 2 is a cylinder, and 2 tops, swirling flow chamber are connected with swirling flow contraction chamber 3, and swirling flow contraction chamber 3 is a conical structure, and awl diffusion angle is 30
0-120
0, the atomizer that swirling flow contraction chamber 3 and convergent jet pipe 4 and divergent nozzle 6 are formed links to each other, convergent jet pipe 4 and divergent nozzle 6 adopt the Rafael nozzle shaped design, throat diameter be 5-20mm with definite corresponding flow, convergent jet pipe 4 taper angle are 5-30
0, divergent nozzle 6 flaring angles are 30-60
0 Divergent nozzle 6 is connected with jet expansion 5, be provided with nozzle air inducing hole 7 around the jet expansion 5 and hide water along 8, nozzle air inducing hole 7 diameters are 1-3mm, and quantity is 12-60, and its width is 0.5-3mm, the air inducing flow direction is vertical with nozzle current emission direction, in order to guarantee that the atomizing uniformity prevents that the hollow phenomenon of nozzle from taking place, hide water along 8 highly be 3-10mm with the different diffusion angle of correspondence, it spreads angle is 0-20
0Introduce air capacity with the atomizing secondary that correspondence is different, jet expansion 5 is with nozzle air inducing hole 7 and hide water along 8 combination control diffusion angle and trickle uniformities, corresponding different water quality, and material adopts engineering plastics or stainless steel.
During work, hot water enters shower nozzle by swirling flow water inlet pipe 1, combining with tangent swirling flow chamber 2, the hot water of import department has bigger radius of curvature, along with the center flow of hot water to the swirling flow chamber, according to conservation of angular momentum principle, radius is more little, its tangential velocity is big more, has higher rotary speed when entering convergent jet pipe 4, divergent nozzle 6 jet pipes, and higher tangent line rotary speed helps water droplet and overcomes surface tension and form less atomizing particle size.Go out the interruption-forming negative pressuren zone at jet pipe, nozzle air inducing hole 7 has been designed in the lower end, benefit wind by the bottom, strengthen the atomizing of water droplet, because the air-flow direction in nozzle air inducing hole 7 is to center air inducing, intersect simultaneously, strengthened the exchange of conducting heat on the one hand with the water outlet direction, make the part water droplet drop on the central area on the other hand, alleviated atomizer hollow phenomenon.For the gentle water ratio of the diffusion angle of more effectively controlling hot water, around nozzle, arranged screening water along 8, atomization angle can be controlled by hiding water along 8, and the generation of wall flow phenomenon can be reduced.
