Description
Technical field
The utility model relates to the scientific research and development equipment in a kind of sonochemistry and environmental protection field, refers in particular to the sound cavitation effect frequency effect research apparatus that is prime mover, concerns between the degradation effect of handling phenols or dyestuff organic waste water under strict acoustics, the electrical conditions with the research power ultrasonic and power ultrasonic frequency.
Background technology
Water resources is one of valuable source that maintains human survival and development.In recent years, along with the raising of industrialization degree in the socio-economic development process, all types of industries waste water is discharged into occurring in nature in a large number, has brought serious threat for existent environment of people and health.Especially containing and be easy to generate after the phenols organic waste water of difficult degradeds such as phenol, p-NP, para-chlorophenol and dyestuff organic wastewater are absorbed by the body " three cause " harm of " carcinogenic, teratogenesis shape, cause transgenation ", is the killer of serious threat human health.Ultrasonic water technology is the novel water technology that development in recent years is got up, and the cavitation effect that it produces when utilizing power ultrasonic effect liquid medium comes the organic pollutant in the degradation water.This technology integrates technology such as advanced oxidation, pyrolysis, supercritical oxidation, and simple to operation, degradation speed is fast, can use separately or unites use with other water technologies, has very big potentiality and applications well prospect.
Ultrasonic water treatment is a new technology that relates to multidisciplinary mixing together such as acoustics, chemistry, electricity.Because that be engaged in the research work is the experts and scholars of chemical industry, environmental area mostly, so chemical parameters such as the pH value of solution, starting point concentration, temperature of reaction have been carried out research in depth to the mechanism that influences of degradation effect, but the parameters,acoustics such as sound field distribution in ultrasonic frequency, sound power/sound intensity and the phonochemical reaction device have been lacked enough research.A large amount of experiment conclusion show that ultrasonic frequency is one of important parameter of the ultrasonic water treatment degradation effect of influence.The frequency of ultrasonic scope is 20kHz-1000MHz, and the ultrasonic frequency that is generally used for water treatment is 20kHz-2MHz.Ultrasonic wave is when low frequency, and cavitation bubble is few but diameter is big, and cavitation bubble has obvious growth, collapse process, and cavitation nucleus reaches resonance vibration at first strongly during radius in the sparse stage, the moment collapse of collapsing then, thereby explosion is more fierce; When high frequency, the formation of cavitation bubble and collapse become faster, and the free radical of generation is easier to be entered in the liquid phase main body, but the acoustics cycle is short, and the cavitation bubble diameter is little, the big but weak strength of the cavitation limit.Therefore separate reaction for the sound based on pyrolysis, when the sound intensity during greater than cavitation threshold, along with the increase of frequency, the sound cycle shortens, and the cavitation bubble number increases, and sound is separated the efficient raising; And for the DeR based on free-radical oxidn, when ultrasonic frequency was higher, then the cavitation bubble particle diameter was little, the cavitation strength reduction, and sound is separated efficient and is reduced on the contrary.Therefore, also different to the best ultrasonic degradation frequency that contains different organic its correspondences of organic solution.Just be based on above reason, " frequency effect " research in the phonochemical reaction has been subjected to more and more scholars' attention.
So-called " frequency effect " be meant and guaranteeing under the identical condition of sound field parameters such as sound power, the sound intensity, only because of the influence of the different ultrasonic wave of frequency to the sonochemistry yield.Chinese scholars is in the research process that carries out ultrasonic water technology at present, mainly carry out Degradation at mimic phenols polluted-water and waste water from dyestuff with frequency fixing or the very narrow ultrasonic source of frequency band, though can obtain the frequency effect of this water body degradation effect in narrow band very or a small amount of fixed frequency time effect to this water body degradation effect, these limited data are far from being enough to the Physical Mechanism of research supersound process waste water.In general, ultrasound wave irradiation existence in the waste water process of handling different substances makes cavitation effect the strongest one or more frequencies or frequency range.Frequency factor is the important factor of the ultrasonic water treatment effect of influence, compares with other factors that influence treatment effect, also is the least sufficient factor of studying at present.
At present, relate to and utilize the ultrasonic disclosed patent application of method and apparatus of carrying out water treatment to have: 1, application number is 200410004355.4, and name is called: " intensified by ultrasonic wave biological method for treating waste water ".2, application number is 200320126506.4, and name is called: " ultrasonic wave water treatment system ".3, application number is 200610046997.X, and name is called: " a kind of efficient crude-oil treatment system and dehydration treatment method ".These three kinds of patent applications all be utilize ultrasonic separately and the ultrasonic in combination other technologies method or the device that carry out water treatment, but as the fundamental equipments of these methods of research and development or device, promptly frequency effect research apparatus does not appear in the newspapers as yet.
