The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, steam-jet heater arranges in turn connected fluid A inlet tube 3, fluid tip, mixing tube and fluid-mixing outlet 14 from left to right, mixing tube is provided with the fluid B inlet tube 18 communicating with it, fluid A can be steam or liquid, and fluid B can be also steam or liquid.Wherein, mixing tube comprises that the first mixing tube 8, the second mixing tube 9, the first mixing tube 8 angles of flare that arrange are from left to right a1, and the second mixing tube 9 angles of flare are a2, and wherein, a1 is less than a2, and a1 is greater than 0.The mode of this secondary diffusion, makes caliber continue to increase along fluid flow direction, and in the second mixing tube 9 parts increase by a larger margin.Because the flow of fluid-mixing is constant, so along with the increase of mixing tube caliber, the cross-section of pipeline that fluid-mixing is flowed through increases, cause flow velocity to reduce.According to Bernoulli equation, the gross energy conservation of fluid-mixing, flow velocity is lower, and pressure is larger.The viscosity that fluid-mixing has because of fluid while flowing in pipeline can produce the pressure loss, the mode of secondary diffusion in mixing tube, can make the friction loss of fluid-mixing minimum, realize the fast quick-recovery of pressure and rising simultaneously, the pressure loss problem while solving fluid mixing.
Fluid tip is swirl nozzle 5.Flow through swirl nozzle 5 of fluid A produces High Rotation Speeds, and at the inner eddy flows that produce of swirl nozzle 5, when fluid A gushes out swirl nozzle 5, eddy flow can develop and form turbulent flow, the fluid atomizing of ejection simultaneously, and the atomizing effect of swirl nozzle 5 is good.Fluid B mixes with the turbulent fluid A through atomization the mutual impact minimum producing through oblique circular hole, reduces and overcome the vibration defect problem of traditional steam-jet heater.
The outside of mixing tube encloses the shell 10 of sealing, and shell 10 comprises left cover 4, housing and right cover plate 13.Shell 10 tops are provided with the opening communicating with fluid B inlet tube 18, and some fluid B that distribute on mixing tube enter hole 17, between shell 10 and mixing tube, form fluid cavity.Fluid B enters fluid cavity along fluid B inlet tube 18, then through fluid B, enters hole 17 and enter mixing tube, and A mixes mutually with fluid.
The left and right two ends excircle of mixing tube is installed respectively vibration damping device A and vibration damping device B, and vibration damping device A and vibration damping device B are positioned at fluid cavity and are fixed on shell 10 inwalls.The design of vibration damping device A7 and vibration damping device B8 has further been eliminated fluid A and fluid B when mixing tube mixes, the vibration of impacting, colliding and causing.
The interface of the interface of swirl nozzle 5 and mixing tube and fluid-mixing outlet 14 and mixing tube is mounting sealing device A6 and sealing device B7 respectively.Can prevent that steam or liquid from leaking outside at interface, can absorb vibration, there is weakening effect simultaneously.Sealing device A6 and sealing device B7 can be the various ways such as gasket seal, sealant sealing, soft packing seal.
Fluid A inlet tube 3, fluid-mixing outlet 14, fluid B inlet tube 18 outer ends arrange respectively fluid A inlet tube flange 2, fluid-mixing outlet flange 15, fluid B inlet tube flange 19.Fluid A inlet tube 3 is connected with fluid A import 1 by fluid A suction flange 2, and fluid-mixing outlet 14 is connected with fluid-mixing outlet 16 by fluid-mixing outlet(discharge) flange 15, and fluid B inlet tube 18 is connected with fluid B import 20 by fluid B suction flange 19.
The second mixing tube 9 right-hand members connect the mixing tube that angle of flare successively increases successively.According to required fluid pressure actual conditions, can after the second mixing tube 9, connect the mixing tube of larger angle of flare.
Fluid B enters hole 17 for the spaced apart oblique through hole of circle being located on mixing tube, and the direction of oblique through hole is pointed to the Way out of fluid-mixing.According to technical conditions, also can manufacture and design the circular hole of different sizes or the hole of other shape, be convenient to fluid B and enter in the first mixing tube 8 and the second mixing tube 9.
The following describes the course of work of steam-jet heater: fluid A inlet tube 3 is connected with fluid A import 1 by fluid A suction flange 2, fluid-mixing outlet 14 is connected with fluid-mixing outlet 16 by fluid-mixing outlet(discharge) flange 15, and fluid B inlet tube 18 is connected with fluid B import 20 by fluid B suction flange 19.Fluid A is by flowing to swirl nozzle 5 after fluid A inlet tube 3, High Rotation Speed sprays forward, and successively enters in the first mixing tube 8 and the second mixing tube 9 that angle of flare is respectively a1 and a2.Because injection water flow velocity is high especially, change pressure energy into speed energy, make air-breathing district pressure decreased produce vacuum, fluid B is entered to hole 17 by the fluid B on the first mixing tube 8 and the second mixing tube 9 and be drawn in mixing tube, and with fluid A rapid mixing, carry out energy and momentum exchange.When the fluid-mixing that comprises fluid A and fluid B is flowed through mixing tube, along with the increase of caliber, flow velocity reduces, and increased pressure exports 16 from fluid-mixing and flows out.
As can be seen from the above embodiments: in the utility model the first mixing tube 8 and the second mixing tube 9, adopt respectively the design of angle of flare a1, a2, wherein, a1 is less than a2, the mode of this secondary diffusion, caliber continues to increase along fluid flow direction, and in the second mixing tube 9 parts increase by a larger margin, rate of flow of fluid is reduced rapidly, pressure increases, and realizes the fast quick-recovery of the pressure of fluid and rising in mixing tube.Meanwhile, adopt the design of swirl nozzle 5, High Rotation Speed during fluid-mixing process swirl nozzle 5, and at the inner eddy flows that produce of swirl nozzle 5, when fluid A gushes out swirl nozzle 5, eddy flow can develop and form turbulent flow, while fluid A atomization.When impacting when fluid B mixes with the turbulent fluid A of atomization, clashing into, the energy of loss is little, overcomes the vibration defect of traditional steam-jet heater.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
