Abstract

The utility model relates to a combined swirl atomized jet nozzle. Two or more than two swirl atomized jet nozzles 1 are symmetrically fixed on the surface of a water chamber, the water chamber is connected with an external water inlet pipe by a stationary connector. The nozzle 1 or the utility model can also adopt an outer jet type, namely, after a water injecting nozzle is outside provided with a jet sleeve and an air inlet fairing cone, the water injecting nozzle is fixed on the spherical water chamber which is provided with a water inlet pipe with a connector, and the outer jet type is formed. When water pressure is 0.01 MPa, water is sprinkled into water drops; when the water pressure is 0.05 MPa, mist appears; when the water pressure is 0.1 MPa, spray accompanying with lots of jet wind can reach more than 4 meters. The utility model with low working water pressure, large flow rate and favorable atomized effect is not easily clogged, and the utility model which can replace the existing atomized and splashing nozzles is used for various heat and mass transfer equipment such as cooling equipment, condensing equipment, etc.

Description

Combined type swirling flow atomizing injection shower nozzle

Combined type swirling flow atomizing injection shower nozzle belongs to fluidic (B05B).

" large-flow aspirating multi-layer rotational flow atomized spray injector " that Chinese invention patent 89105926.1 provides is owing to adopt a plurality of little circumferential weld sprayings, and flow resistance is bigger, and is stopped up by silt easily, and its range of application is restricted.Chinese invention patent 89104110.9 " multiple induced jet type swirling-flow atomizing nozzle " improves at above-mentioned shortcoming, change a plurality of circumferential weld sprayings and be the inside and outside injection air-atomizing of multiinjector, and diffusing flow cone is set at jet expansion, and increase outlet flow, improved atomizing effect.But it is big interior eddy flow core and diffusing flow cone flow resistance to occur, and therefore when hydraulic pressure was lower than 0.05MPa, it is big that water droplet becomes, and when flow increases, because of nozzle diameter becomes greatly and the influence that runs foul of each other between drop, more big water droplet also occurs.In addition, in long-time running, under the effect of rotation fluid power, the eddy flow core also can fracture.

The purpose of this utility model is to improve at the problems referred to above, and a kind of combined type swirling flow atomizing injection shower nozzle is provided, under extremely low hydraulic pressure, can spray water droplet and spray spray, and simple in structure, be difficult for stopping up.

The following formation of the utility model: combined type swirling flow atomizing injection shower nozzle, it is characterized in that A. establishes hydroecium 2, fix two and above rotational flow atomized spray injector 1 in surperficial symmetry, shower nozzle water inlet pipe 1.6 axis and horizontal plane angle α are in ± 60 ° of scopes, hydroecium inlet opening face directly is connected with the external pressure water inlet pipe with static connector 3; Or B. the utility model or aforementioned rotational flow atomized spray injector 1, adopt outer injection type, following formation: the injection cover 1.2 that has air admission hole 1.4 more than 1 of placement reaches outside (operating) water nozzle 1.3, refill air inlet fiaring cone 1.1 outside it, this nozzle assembly is fixed in the spherical hydroecium 1.5 of the water inlet pipe 1.6 that band connector 1.7 is housed.Each rotational flow atomized spray injector 1 can equate or do not wait apart from the distance of hydroecium 2.The connector 1.7 of water inlet pipe 1.6 adopts flange 1.7 or screw thread.Hydroecium 2 can be garden cylindricality or sphere.

Further specify below in conjunction with accompanying drawing

Embodiment 1: see Fig. 1, Fig. 2, establish the spherical hydroecium 2 in a garden, surperficial symmetry is fixed 1,4 shower nozzle of 4 outer induced jet type swirling-flow atomizing nozzles and is equated apart from the hydroecium distance, and each is installed at a distance of 90 ° of symmetries.Each α promptly upwards sprays in equating to be+60 °.With external pressure water pipe 4 direct-connected static connectors be ring flange 3.See Fig. 3, (operating) water nozzle 1.3 adopts convergence one expanding.Injection cover 1.2 adopts the garden cylindricality or the taper of thin-walled, herein with 1 garden cylindricality injection cover 1.2.Air inlet fiaring cone 1.1 has cone-shaped inner hole, and this nozzle assembly is fixed in the spherical hydroecium of thin-walled 1.5 tops of perforate, and the water inlet pipe 1.6 of flanged 1.7 (being connector 1.7) then is connected with spherical hydroecium 1.5 outer wall lower tangential.Connector 1.7 (flange 1.7) is to be used to connect rotational flow atomized spray injector 1 and hydroecium 2 (see figure 1)s.

Embodiment 2: outside the utility model adopts during injection type, and its structure such as Fig. 3, identical with outer induced jet type swirling-flow atomizing nozzle 1 structure, only connector 1.7 is used for directly being connected (see figure 3) with external pressure water inlet pipe 4.

The course of work: external pressure water enters hydroecium 2 through ring flange 3 centre bores, is dispensed to each shower nozzle by hydroecium, and current are formed by nozzle 1.3 ejection behind the eddy flow in hydroecium and rotate spray; Mix from air admission hole 1.4 suction air and with spray simultaneously, to drip the ejection of shape or vaporific form.

Techno-economic effect of the present utility model: owing to adopt a plurality of rotational flow atomized spray injectors, improved flow, And make each nozzle diameter size suitably, add and use the hydroecium water distribution, not only guarantee atomizing effect but also make atomizing evenly. With outer injection type shower nozzle, when design parameter mates, with the double effects of be improved atomizing and injection air, Do not have member because of the shower nozzle center again, namely hollow shower nozzle can guarantee stable and reliable operation. Experiment shows that hydraulic pressure exists 0.01MPa the time, water can be sprayed and be water droplet, during 0.02MPa, can obtain tiny water droplet, 0.05MPa with On water can be sprayed into mist, during 0.1MPa, spray height reaches more than 4 meters, and is attended by a large amount of injection airs, phase Answering flow is 1～50m³/ h effectively reduces hydraulic pressure, saves energy consumption. Have working water and force down, flow is big, Atomizing effect is good, and nozzle diameter is big, is difficult for the advantages such as obstructions, alternative existing multiple atomizer and dabbling Shower nozzle is widely used in cooling, in the multiple heat and mass equipment such as condensation and the system.
