The present invention relates to the atomization of liquid and disperse equipment, particularly device for atomizing liquid.
Device for atomizing liquid can be united in the stove at metallurgy, the fogging degree of regulator solution fluid fuel during the liquid fuel active combustion in the manufacture of cement and in the electric device.This device can be used for the atomizing of solution, emulsion, suspension and slurries, for example, can use when chemical industry and other industrial department carry out drying to these liquid.This device also can be used for the spraying of various materials.
The disperse of liquid and atomizing all are significant to various technical fields.
People are familiar with various device for atomizing liquid.
For instance, in the converter of producing alumina and cement, be used for the tape input mouth of atomizing of liquid fuel and burning and the mechanical injection apparatus of discharge spout and (see that E.N. Ha Daoluofu shows " the cement industry stove " the 370th page that building publishing house publishes nineteen sixty-eight, be that people are familiar with Figure 152), the band spiral fluted atomization valve that can vertically move be housed near discharging the spout place.
Liquid fuel heavy oil enters atomization valve by the input port under very big pressure, disperse in helicla flute and rotation, and the liquid of rotation is injected in the burner hearth by discharging spout with the taper form of film, here, and disperse and atomizing under the effect of medium.
Yet this equipment requires high energy resource consumption required high pressure of thin disperse liquid when being created in mechanical atomization.In addition, for the purpose of technology when regulating the shape of fogging degree and fuel flame, must use removable, have a atomization valve with the groove at various angles of inclination.So just make the complicated and need blowing out in short-term of roasting process.
For example at the drying stage of emulsion, suspension or slurries, use for it is atomized a kind of device (see Ю. the China Machine Press that φ. Ji Jiajin etc. is shown published " atomization of liquid " in 1977), this device has carrying liqs and Alevaire input port and discharges the pneumatic machinery injector of spout.Be equipped with and movably be with the spiral fluted atomization valve near discharging the spout place, it forms cannelure in order to the supply Alevaire with the case of sprayer inwall.
Liquid enters atomization valve by injector input port and special groove.Liquid is disperseed in helicla flute and is rotated, and is advancing into doughnut by discharging the spout ejection.Compressed air as Alevaire also enters this chamber, and further atomizing is provided.Air and liquid mixture spray into the working space of this device by the discharge spout.
Yet liquid and Alevaire only just converge directly near the discharge spout time in this device, thereby have shortened interactional approach and time.As a result mixing of liquid and Alevaire, liquid dispersion and atomizing all do not reach quite all degree of even necessity.The intensity of this device atomization process and adjustable range are limited, and the Alevaire consumption is bigger.
Up-to-date technological improvement is a kind of device for atomizing liquid (seeing Russian Patent SU.A.961431), and it has the tape input mouth and discharges the injector of spout.Near injector discharge spout place movably atomization valve is being housed.
Liquid enters atomization valve by the input port under pressure, is disperseed in the helicla flute of this valve or in the tangential slit and rotates.The liquid of rotation sprays in the working space by discharging spout with the form of taper film, here, and disperse and atomizing under the effect of medium.
But this device requires high energy resource consumption equally, to produce liquid turbulent flow and the thin required very high fluid pressure of disperse.Also often need simultaneously in advance liquid to be handled, to reduce its viscosity, for example, surfactant etc. is added in preheating.In addition, when valve being moved when far away from discharging spout,, can observe big drop of liquid at working space and fall because the loss of the moment of momentum that rubs has reduced the atomizing of liquid for the flame profile of adjusting atomized liquid.
Task of the present invention is a kind of device for atomizing liquid of development, and it can improve the intensity of disperse process greatly by the additional atomizing of liquid in blender stream and rotation.
The method that solves this task is a kind of device for atomizing liquid of development, this device has the tape input inlet and discharges the injector of spout, and movably atomization valve is being installed near discharging the spout place, according to the present invention, this device also has the blender that is connected with the injector input port, and this blender has band feed fluid and the input pipe of Alevaire and the mixing chamber of discharge pipe, and corresponding atomization valve, this valve is connected with the input pipe of feed fluid, and has jet exhaust.
This device can improve the intensity of the atomization of liquid and disperse process greatly.
Be the input pipe of blender supply Alevaire, the most handy diaphragm plate that connects spout that is equipped with cuts off, and near any close blender atomization valve spout of the axis of these spouts is crossing.
Can in blender, strengthen greatly like this liquid disperse and with the mixing of Alevaire because the Alevaire air-flow is colliding mutually and has produced the higher-order of oscillation with the liquid stream of the taper rotation Shi Yuqi that meets at a certain angle.
Outer surface at the atomization valve of blender also can replenish except that having helicla flute longitudinal groove is set.
Can strengthen the turbulent flow and the mixing of gas and liquid mixture like this by the interaction of different directions fluid in helicla flute and longitudinal groove.
The longitudinal axis of injector input port is setovered with respect to its longitudinal axis on the cross section of injector.
Like this can be at the disperse of strengthening liquid to a greater extent and atomization process, because gas and mixtures of liquids form the eddy flow that replenishes on two orthogonal planes.
