Embodiment Construction

[0012] As shown in Figure 1, the present invention is a tubular integral body made up of a spray neck 2 that is tapered inside and outside, and a nozzle 1 that is connected to the upper end of the spray neck 2 and that is inverted tapered inside and outside. A right-handed spiral groove 4 is formed on the inner wall of the nozzle neck 2 and the through hole 3 inclined from the outside to the inside, and the spiral groove 4 runs through the entire inner wall of the nozzle neck 2 continuously.

[0013] Of course, the present invention is not limited to the above embodiments, and the spiral groove 4 may be a left-handed or right-handed spiral groove 4 with at least one end and the same direction of rotation.

[0014] The present invention can be obtained by processing a whole piece of iron bar by metal machining method; it can also obtain cast iron blank by casting method, and then process spiral groove 4 and through hole 3 by metal machining method.

Abstract

The present invention discloses one new type of nozzle for the atomizer in industrial no-stuffing water cooling tower. The integrated tubular atomizing nozzle includes one conic nozzle neck with through holes and helical groove in the wall, and one conic spout connected to the nozzle neck. Owing to the nozzle neck with through hole and helical groove, the air through the through holes may be well mixed with water flow and the water flow produces rotating centrifugal force, reaching excellent atomizing effect.

Description

technical field [0001] The invention relates to an atomizing device for an industrial cooling water circulation cooling tower without packing, in particular to an atomizing nozzle of the atomizing device. Background technique [0002] The nozzle is an important part of the final process of the industrial cooling water circulation non-fill cooling tower atomization device. The performance of the nozzle directly determines the diameter of the cooling water atomized droplet, thereby determining the effect of heat transfer and mass transfer. [0003] The authorized announcement date is January 1, 2003, and the Chinese utility model patent with the patent number ZL02215691.7 discloses a nozzle of a vertical flow cooling tower nozzle, which adopts an oval opening design, to a certain extent The atomization effect is improved, but because the outlet hole is designed as a straight hole, it inevitably brings the disadvantage of small diffusion area of ​​the sprayed atomized water flo...
