Description
Technical field
The present invention relates to a kind of firing equipment, particularly utilize the resonance device of microwave heating, belong to the microwave chemical technical field.
Background technology
Microwave heating is a kind of heating that is different from conventional method, and it is inducing molecule polarization and dipole rotation by the interaction of microwave and molecule, causes motion rapidly between the molecule.This method and traditional type of heating are essentially different, and microwave irradiation not only can change the speed of chemical reaction, even can change the approach of chemical reaction.When microwave runs into different medium in transmission course, because the main character such as specific inductive capacity, dielectric loss coefficient, specific heat, shape and water cut of these media is different, will produce reflection, absorption or penetration, therefore the electric field energy that absorbs is different, carries out the selectivity heating.Microwave technology is compared with the traditional heating method has unique effect and advantage; can reduce the reaction time greatly; economize the generation of medium (can lack 50%～90%), energy savings, minimizing refuse than conventional method; improved the purity of yield and extract simultaneously, at utmost reduced the complicacy of aftertreatment, made the chemical reaction environment more towards cleaning and green; pollution-free; belong to green engineering, help environmental protection, it is a kind of new technology with wide development prospect.
Follow the progress of society, constantly work out the new method and the new technology that promote chemical reaction, we should pay attention to using new and high technology, more should pay much attention to the combination of these new and high technologies.When sound wave feeds object,, will the suffered pressure of material be changed because acoustic vibration makes material molecule produce compression and sparse effect.Because the energy that ultrasound wave had is very big, just might make material molecule produce significant acoustic pressure effect, for example when passing through the ultrasound wave of common intensity in the water, the additonal pressure of generation can reach several atmospheric pressures.Cavitation that ultrasound wave has also is a kind of means that promote chemical reaction.
Can utilize not only that microwave heating speed is fast, pollution-free, the characteristics of cleaning, also can utilize common promotion of hyperacoustic advantage to clear up/extract, provide a kind of very special physicochemical environment newly for clearing up/extracting.For Specimen eliminating/extraction provides new laboratory facilities.
Summary of the invention
The invention provides the firing equipment that a kind of new microwave/ultrasonic composite reinforced sample is cleared up/extracted, the resonance device that promptly a kind of microwave/ultrasonic composite reinforced sample is cleared up/extracted newly designs.The technical scheme that the present invention is concrete: it comprises resonator cavity, waveguide lid, microwave input port, ultrasonic oscillator, cut-off waveguide, teflon baffle plate, couplant, clears up/extraction flask; Resonator cavity is a vertical hollow cylinder, is resonator cavity upper flange, waveguide lid above, is screwed between the two; Waveguide has covered the cut-off waveguide mouth; The resonator cavity sidewall opening links to each other with the microwave input port, and a teflon baffle plate is fixed in the exit, ultrasonic oscillator is fixed on the resonator cavity bottom with glue, intra resonant cavity is put into couplant, clears up/extraction flask puts into couplant, clears up/put into the medium of clearing up/extracting in the extraction flask.
Beneficial effect of the present invention:,, provide a kind of new very special physicochemical environment for clearing up/extracting, for Specimen eliminating/extraction provides new laboratory facilities with two kinds of organic combinations of means that promote Specimen eliminating/extraction with the contrast of prior art.
