Description
Technical field
The utility model relates to a kind of ultrasound-enhanced supercritical fluid extraction device.
Background technology
The ultrasound-enhanced supercritical fluid extraction technology is nearly technology that worked out in 2 years, and it is an additional ultrasonic field in supercritical fluid extraction, reduces extracting pressure and extraction temperature, shortening extraction time to reach, finally improves the technology of extraction yield purpose.Make extract clasmatosis can directly improve extraction efficiency or fast reaction speed by ultrasonication; Variation is a kind of check system of ultrasonic effect to make cavitation test material (aluminium foil) produce the cavity or to break etc., helps to carry out the mechanism research of ultrasound-enhanced extraction efficiency.More than 2 in ultrasound-enhanced supercritical fluid extraction research with in producing important effect is arranged, and these 2 relevant with ultrasonic power density in the extraction kettle.Use the device of this technology to have two kinds at present, a kind of is that built-in another kind is an external.Built-in is that ultrasonic transducer is directly installed in the high pressure extraction still, make ultrasonic wave directly be radiated in the spe medium, can reduce the loss of ultrasonic energy in the extraction process like this, the utilization rate height of ultrasonic energy, but its shortcoming is: owing to be subjected to the restriction of size, the large power supersonic transducer can't be installed.The built-in ultrasound-enhanced supercritical fluid extraction device of being reported at present, its extraction kettle is many about 1L, because the restriction of existing ultrasonic transducer production technology has only low power ultrasonic transducer can be installed into extraction kettle in this volume.Data shows that the maximum ultrasonic power density of the existing built-in design of ultrasonic transducer is 200W/L, and the ultrasonic transducer that electromotive power output is 200W promptly is installed in the extraction kettle of 1L volume.Because ultrasonic power density is not enough, make existing built-in extraction equipment not, variation such as can not make cavitation test material (aluminium foil) produce the cavity or break for the clasmatosis of extracting raw material.The built-in in addition ultrasonic transducer that is not easy to dispels the heat, and the heat that produces in the ultrasonic transducer course of work can only be directly passed to supercritical fluid, influences the control of temperature during extraction process, and reduces the working life of ultrasonic transducer.And the external design though supersonic transducer power is unrestricted, can produce very big ultrasonic power density in extraction kettle.The ultrasonic power density of existing external design can reach 300W/150ml, and promptly volume is the ultrasonic electromotive power output that can reach 300W in the extraction kettle of 150ml.Under this ultrasonic power density, can be with extract clasmatosis, and can make cavitation test material (aluminium foil) produce the cavity or variation such as break.It is too low that but external designs hyperacoustic utilization rate, energy loss is bigger, particularly owing to the special construction of supercritical extraction reactor, ultrasonic wave will just can act on material and fluid by very thick high-pressure bottle wall and material basket, and the hyperacoustic loss of whole process is very big.There is its ultrasonic wave rated output power of document announcement external ultrasound-enhanced supercritical fluid extraction experimental provision to have only 60% utilization rate.Therefore external only is applicable to the laboratory usually.
The utility model content
The purpose of this utility model is to provide a kind of existing enough ultrasound functions density, can high efficiency utilize hyperacoustic ultrasound-enhanced supercritical or subcritical fluids fluid extraction device again.
This ultrasound-enhanced supercritical that the utility model provides or subcritical fluids fluid extraction device, comprise extraction kettle, ultrasonic transducer, the luffing bar, the luffing bar is installed on the extraction kettle with its node place, described ultrasonic transducer is positioned at outside the extraction kettle, luffing bar one end is connected with ultrasonic transducer, and the other end puts in the extraction kettle.
Ultrasonic amplitude transformer can amplify the particle displacement of mechanical oscillation or speed, or ultrasonic energy is concentrated on the less area is cumulative, therefore also claims ultrasonic gear lever or supersonic concentrator.End face at ultrasonic transducer connects ultrasonic amplitude transformer, the mechanical oscillation amplitude can be amplified, can also can between ultrasonic transducer and acoustic load, carry out impedance matching as the mechanical impedance converter, make ultrasonic can more effectively the transmission to load from ultrasonic transducer.On the other hand, the luffing bar is when doing the longitudinal extension vibration, and the particle movement direction of certain the cross section the right and left in the middle of it is just opposite, is equivalent to exist a static relatively nodal section.This nodal section is called node, also is the optimal fixation point of ticker here.
The utility model has made full use of the characteristic of luffing bar, by node the luffing bar is fixed on the extraction kettle, can guarantee the sealing of extraction kettle well.Ultrasonic transducer is connected with the luffing bar, not only the energy efficient transmission is advanced in the extraction kettle by the luffing bar, has also changed amplitude and has produced better strengthening extraction effect.This structure of the utility model makes ultrasonic transducer not be subjected to the restriction of installation dimension, has increased the scope of power selection.Guaranteeing to import the ultrasonic wave of sufficient intensity in the extraction kettle, and the influence of the heat that produces in the ultrasonic transducer course of work be can avoid, ultrasonic transducer good heat dissipation, long working life made extraction process.The more important thing is the big capacity extraction still that the utility model is used for industrial production, more than one ultrasonic transducer can be installed as required, also can adopt the ultrasonic transducer acting in conjunction of different frequency, produce better strengthening effect.Therefore the utility model device can produce bigger ultrasonic power density with existing built-in comparing in the extraction kettle of same volume, compares with existing external to have higher ultrasonic energy utilization rate.
Device of the present utility model can be applicable to ultrasound-enhanced supercritical or subcritical fluid extraction aspect, also can be applicable to overcritical or aspect such as subcritical fluids dyeing, water oxidation, fine particle preparation.
