Abstract
The present invention discloses a circulation type multi-stage ultrasonic dispersion machine and a dispersion method thereof. Multi-stage ultrasonic dispersion devices of different power and different frequency are orderly and serially connected. A mix liquid in a storage tank is continuously pumped out by a pump, and is delivered to an inlet position of a first stage ultrasonic dispersion device. The mixed liquid dispersed after the first stage ultrasonic dispersion device is orderly delivered to a second stage ultrasonic dispersion device and a third stage ultrasonic dispersion device for dispersion by the pressure provided by the pump. Thus, the multi-stage ultrasonic dispersion is circularly carried out until the preset dispersion requirement is obtained, and the dispersion work stops. Sludge in the fuel oil can be pulverized by the present invention, and completely homogenizes, and the precision level set by micron order is obtained. Because the high efficient circulation multi-stage ultrasonic dispersing machine is adopted, the energy consumption can be reduced. The present invention has the advantages of miniaturization, small occupation area, simple maintenance and very high dispersion efficiency.
Description
Technical field
The present invention relates to field of dispersions, relate in particular to the circulating multi-stage ultrasonic dispersion machine.
Background technology
One as particle state, in mutually is to be called disperse system being scattered in other, and particle is called dispersate or decentralized photo, and other that becomes medium is called dispersion medium or continuous phase mutually.
Can be divided three classes by dispersed particle size disperse system:
(1) macroscopic view (thick) disperse system
(2) colloid disperse system
(3) molecule disperse system
In first kind of disperse system, the particle diameter of dispersion is more than 0.1 μ m.
The general decentralized photo that constitutes disperse system has gas, liquid, solid, and dispersion medium also can be gas, liquid, solid etc.Dispersing liquid phase time wherein, maximum is emulsion or is called emulsion; Corresponding with it dispersing solid phase time, that often sees is called the liquid that dangles; Disperse gas mutually and during the colloid of particle diameter below 0.1 μ m, be called as the foam colloid.In order to illustrate that minuteness particle has various character, study the relation of decentralized photo volume and surface area earlier.When the radius of particle was the ball of r, its surface area was 4 π r
2, its volume is 4 π r
3/ 3, so each cm
3Surface area be 3/rcm
2, promptly diameter is the ball of 1 μ m or 0.1 μ m, each cm
3Pure area be respectively 6m
2Or 60m
2Therefore, because material by refinement, becomes particulate, then the surface area of unit volume just becomes quite big, and when existing absorption dissolving or chemical reaction between two kinds of objects, they just can play huge facilitation.
Contact in maximum emulsion disperse systems people, two that form emulsion is respectively water and oil mutually.Its discrete form has following two classes:
Oil droplet type in the water (being called for short the O/W type);
W/O drips type (abbreviation w/o type).
In fact running into maximum is the O/W type.Milk, ice cream, mayonnaise and the salad juice etc. in the daily life of having that belong to this form.That is to say that milk or ice cream are the fine spherical grains dispersions of aqueous phase fat; What belong to w/o type and be example has butter oil and a margarine.It is the tiny spherical series of disperseing of water in the oil phase.
This emulsion sees it is unsettled series from the thermodynamics viewpoint.Will keep the emulsion state for a long time, add the material that makes its stabilisation, people are called emulsifying agent to this material usually.The stabilization of emulsifying agent is because material is attracted to the result of particle surface; Be to reduce oil-water boundary tension force after all.If adopt ultrasonic dispersion, then do not need to use emulsifying agent, in many occasions, ultrasonic emulsification can obtain the following particle of 1 μ m.The generation of this high-quality emulsion can be thought because near the formed result of the powerful cavitation of the ultrasonic wave the dispersion instrument.
In fields such as chemical industry, pharmacy, biology, dyestuff, food, communications and transportation, military affairs, need disperse the solid particle in the liquid, biological tissue or two kinds of liquid and two or more liquid etc.Adopt conventional methods such as mechanical agitation, polishing, comminution by gas stream and emission cigarette bullet method to disperse, mainly have five big problems:
(1) disperse the back particle big, particle size is usually more than 10 μ m;
(2) particle is inhomogeneous, and the size dispersion scope is big;
(3) dispersion efficiency is low;
(4) floor space is big;
(5) production cost height.
(6) do not give full play to by the physics of dispersed substance, chemical action.
