Preferably, in the utility model, described base upper surface outwards forms a descending slope from the center, and described descending slope is smaller or equal to 30 °.This shunting platform inclination degree than existing nozzle is bigger, so can better form the umbrella face of the spray that needs when spraying.
Preferably, in the utility model, described nozzle entrance is provided with chamfering, and the angle of described chamfering is more than or equal to 35 ° and less than 45 °, and this conveniently is fit into sparge pipe with nozzle.
Because the splitter box opening of the previous described nozzle of patent (ZL 201120494237.1) is darker, reduced the fastness of nozzle base, make and damage owing to current are excessive through regular meeting when nozzle uses.Therefore, in the utility model, the degree of depth of described splitter box is foreshortened to smaller or equal to 20mm; In addition, the diameter of shunting platform also further is enlarged to 50-100mm, and the spray that forms when nozzle is used is bigger than traditional, and has strengthened the area of spray and the fastness of nozzle self.
In addition because the previous described nozzle of patent (ZL 201120494237.1) has influenced the fixedly installation of the crossbeam of sparge pipe owing to highly lower when mounted, therefore, in the utility model, the whole height of nozzle is increased to 65mm-80mm, so just can not influenced the installation of water pipe built-in beam.And, therefore this nozzle also can apply in downflow type and the reverse-flow two kinds of evaporative condensers, and the nozzle of previous design process is surveyed the back because the problem of height dimension can only apply to the downflow type evaporative condenser, so the utility model has been widened the utilization face of nozzle.
In addition, preferably, in the utility model, the quantity of described splitter box is 4,6 or 8.
Based on above-mentioned setting, nozzle provided by the utility model has been cancelled second outlet originally, i.e. the design of base central opening compared to the described nozzle of previous patent (ZL 2,011 20494237.1).This be because, find that through the actual measurement back second on the nozzle base exports the effect that does not have essence, current are through the straight line that is shaped as under the second outlet back sprinkling, no umbrella face, reduced the spray uniformity, because second outlet is more approaching with splitter box, also reduce the fastness when nozzle uses in addition, reduced service life.Therefore the utility model has been removed the second previous outlet in design, and the water yield by second outlet in original nozzle that designs is sprayed to condenser coil through splitter box and the branch stream interface of shunting platform uniformly, has improved nozzles spray uniformity and spray effect.
