Abstract

The utility model discloses a sprayer of a pack-less cooling tower atomizing device for circulation of industrial cooling water. The sprayer is an integrated pipe that consists of a cone-shaped spraying neck (2) and a reversed cone-shaped nozzle (1) that is connected with the spraying neck (2). Inner wall of the spraying neck (2) is provided with spiral grooves (3); by virtue of the spiral grooves (3) on the inner wall of the spraying neck (2) and the design of opened reversed cone-shaped nozzle (1), when high speed currents flow through the spraying neck (2) of varied diameters, the currents produce revolving centrifugal force with the function of the spiral grooves (3); and with the function of the revolving centrifugal force, once the currents squirt out of the reversed cone-shaped nozzle (1), the currents have broader diffusion area, thus having better atomizing effect.

Description

A kind of shower nozzle

Technical field

The utility model relates to a kind of atomising device of industrial colling circulation cooling tower without filling material, particularly relates to a kind of shower nozzle of atomising device.

Background technology

Shower nozzle is the important spare part of the last flow process of industrial colling circulation cooling tower without filling material atomising device, and the performance of shower nozzle directly determines the size of cooling water atomized drop diameter, thereby determines the effect of heat transfer, mass transfer.

Granted publication day is the nozzle that Chinese utility model patent that January 1, the patent No. in 2003 are ZL02215691.7 discloses a kind of vertical current force cooling tower jet pipe, it has adopted oval-shaped opening design, improved atomizing effect to a certain extent, but because its outlet opening designs for straight hole, bring the little shortcoming of atomization flow diffusion area of ejection inevitably, thereby influence is conducted heat, the effect of mass transfer.

Summary of the invention

The purpose of this utility model provides to be had open spout and more a kind of shower nozzle of high heat transfer effect is arranged.

For achieving the above object, the technical solution of the utility model is a kind of shower nozzle, and mainly a tubulose integral body of being made up of the spout that is back taper on tapered spray neck, the spray neck is shaped on helicla flute on its spray neck inwall.

Described a kind of shower nozzle, its spiral fluted rotation direction are a kind of in the left-handed and dextrorotation.

Described any shower nozzle, its spiral fluted groove number is at least one and rotation direction unanimity.

Be shaped on helicla flute on the spray neck inwall of the present utility model, spout is the open by design of back taper, when current are at a high speed flowed through the spray neck of reducing, because the spiral fluted effect makes current produce rotary centrifugal force, under the rotary centrifugal force effect, in case behind the spout of current ejection back taper, current just have wider diffusion area, thereby atomizing effect is also better.

Description of drawings

Fig. 1 is a main cutaway view of the present utility model.

Identify among the figure: the 1-spout, 2-sprays neck, 3-helicla flute.

The specific embodiment

As shown in Figure 1, the utility model mainly by the tapered spray neck 2 in inside and outside, be connected on the spray neck 2 and a tubulose integral body that the about spout 1 that is back taper is formed, it sprays the helicla flute 3 that is shaped on a dextrorotation on neck 2 inwalls.

Certainly, the utility model does not limit to above embodiment, and helicla flute 3 can be the helicla flute 3 that is at least the left-handed or dextrorotation of one and identical rotation direction.

The utility model can be processed a monoblock irony bar by metal machine adding method and obtain; Also can obtain cast-iron blank, process helicla flute 3 etc. by metal machine adding method again by casting method.

Claims (3)

1. shower nozzle mainly is the tubulose integral body that the spout (1) of back taper is formed by tapered spray neck (2), spray neck (2) upper end, it is characterized in that: spray on neck (2) inwall and be shaped on helicla flute (3).

2. a kind of shower nozzle according to claim 1 is characterized in that: the rotation direction of helicla flute (3) is a kind of in the left-handed and dextrorotation.

3. any shower nozzle according to claim 1 and 2 is characterized in that: the groove number of helicla flute (3) is at least one and rotation direction unanimity.
