Description
Technical field
The utility model relates to a kind of used for cooling tower spraying and splashing facility, especially a kind of three splashing type shower nozzle.
Background technology
In the cooling tower industry, being used for tubular type water distribution or tube seat convolution water distribution spraying and splashing facility generally is to adopt various forms of shower nozzles, the spraying and splashing facility of particularly big flow cooling tower water distribution.
In the water dispensing apparatus of cooling tower, owing to consider efficiency of economic operations and cost factor, generally adopt the shower nozzle of reflection-type or nozzle and splash dish unpack format at present, as pipe-dish formula spraying and splashing facility, multilayer shower nozzle, the individual layer shower nozzle etc. that dabbles that dabbles.These shower nozzles are made up of nozzle and water spreading disc.Current spray from ozzle, penetrate on water spreading disc, after reflex, become drops to trickle down on filler more uniformly.But the water droplet that this class shower nozzle forms is thick, and radial distribution is inhomogeneous, and easily forms the umbrella moisture film, makes the water distributing tray below " hollow " phenomenon occur; Under particularly big, the long-time running situation, very easily produce coming off of shower nozzle deflection and splash box (dish), even nozzle occurs and penetrate the phenomenon that water column washes out filler, influenced the whole tower performance of cooling tower greatly at flow.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of novel splash shower nozzle, the deficiency that overcome that the water droplet that the existing structure shower nozzle exists is thick, radial distribution is inhomogeneous, easily form the umbrella moisture film, " hollow " phenomenon appears in the water distributing tray below; Or under, the long-time running situation big at flow, the coming off even nozzle ejaculation water column occurs and wash out the phenomenon of filler of shower nozzle deflection of Chan Shenging and splash box (dish) very easily, thus can improve the whole tower performance of cooling tower by using a kind of new type nozzle.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of three splashing type shower nozzle, have the external screw thread doleiform interface and the taper ozzle that link to each other with sparge pipe, in the bottom of taper ozzle also successively coaxial spaced be provided with big splash box, little splash box and taper and ward off head; Big splash box, little splash box and taper are warded off head and are had structure that external diameter diminishes successively and be fixed on the external screw thread doleiform interface by the connecting rod of at least two vertical settings of circumferential arrangement, on big splash box and little splash box, also be respectively arranged with coaxial and compare fast water hole and the little leaking hole that internal diameter diminishes successively with taper ozzle end opening internal diameter with the taper ozzle, big splash box and little splash box are cambered surface hemispherical up, it is the taper that cone angle makes progress that head is warded off in taper, is respectively arranged with the big sawtooth and the little sawtooth of circumferential arrangement in the nearly outer ring of big splash box and little splash box; Ward off the head bottom in taper and also can be provided with dentation crack tank.
In order to reduce the manufacturing cost of this shower nozzle, described shower nozzle is an integral structure, adopts compression molding to make, and material can be selected ABS plastic or other material for use.
In order further to be beneficial to water spray, described connecting rod cross section is oblate, and the direction of oblate major axis is identical with the radial line direction of big splash box; Described big splash box up the curvature of cambered surface less than the little splash box curvature of cambered surface up; The cone middle part that head is warded off in described taper is provided with the rectangular channel inside from both sides.
The utility model is a kind of to the dabble modified of shower nozzle of existing three layers of disc type in fact, remove and to have possessed the dabble advantage of shower nozzle of original three layers of disc type, also further three layers of splash box are designed to bulging structure and on the border of three layers of splash box, all are provided with sawtooth or ward off tank.
The beneficial effects of the utility model are that the shower nozzle technology of having improved of the present utility model has following advantage:
1, generally adopt nozzle and splash dish unpack format at present, the utility model can form with integrated the moulding of light-duty material ABS, easy for installation and solved when flow bigger, during long-time running, and easily produce the shortcoming that shower nozzle deflection and splash box (tooth) come off.Locking retaining of spray-head interface band and hatband prevent that shower nozzle from coming off, the infringement filler.
2, improved splash box, on former three splashing type shower nozzle splash box, set up the foliaceous sawtooth, but, can abolish moisture film on the other hand by sawtooth one side refinement water droplet.
3, invented the novel head of warding off, warded off head at present and generally adopt cone, the utility model can along the connecting rod face, cut away two rectangle sections at the cone middle part on former sloped footing, promptly be provided with the rectangular channel inside from both sides at the cone middle part; Cone base is provided with dentation crack tank, can effectively increase the middle part water yield of spraying and splashing facility, and the middle part water droplet is evenly distributed.This method has solved the shortcoming that " hollow " phenomenon easily takes place spraying and splashing facility commonly used.
4, increased the middle circle hole radius of splash box, runner is unobstructed, is difficult for stopping up, and guarantees that long-term operational effect is stable.
5, this utility model global design is reasonable, and is compatible better between each parts, can adapt to big working head ground and change.
