Description
Technical field
The utility model relates to a kind of wastewater treatment equipment, belongs to the environmental protection equipment technical field, particularly relates to a kind of double-frequency ultrasound chemical reactor.
Background technology
Along with the quickening of process of industrialization, the sewage of discharging in the every profession and trade industrial enterprise production process is more and more, and municipal water is polluted serious day by day.The high-concentration organic sewage difficult to degrade of chemical industry, dyeing discharging particularly, complicated component, the organic concentration height has higher requirement for treatment process and equipment.Ultrasonic technique has special advantages as a kind of physical means and instrument at processing difficult degradation organic polluting water.The ultrasonic degradation organism mainly utilizes acoustic cavitation.Acoustic cavitation is the physical chemical phenomenon of a kind of complexity in the liquid, and the small complex in the liquid is intensified under ultrasonication, shows as vibration, growth, contraction, the final collapse at a high speed of complex, and collapse can produce very brief very big high temperature, high pressure, high-strength electric field.The water vapour that enters in the cavitation bubble issues estranged splitting at high temperature and high pressure, produces hydroxyl radical free radical (OH), strong oxidizing property matter such as O, HOO; Simultaneously, shockwave and jet that cavitation bubble collapse produces, they are diffused in liquid-gas interface and the whole solution and with organic pollutant generation oxidizing reaction, its oxygenolysis is become other better simply molecule, finally generate carbonic acid gas and water.
In the existing literature report, the overwhelming majority adopts the mode of single-frequency ultrasound wave irradiation, yet, the hyperacoustic propagation waveform of single-frequency all is that a series of crests and trough are arranged, and crest is represented the sound pressure amplitudes maximum, and its cavitation effect is also the strongest, trough is represented the sound pressure amplitudes minimum, and promptly cavitation is the most weak.So, in order to make ultrasonic wave all is that the cavitation effect is strong in treatment solution everywhere, just need another frequency ultrasonic wave and remedy last hyperacoustic trough, promptly allow back one frequency ultrasonic wave crest remedy last ultrasonic wave trough, last hyperacoustic crest remedies back one hyperacoustic trough, and the double frequency composite ultraphonic has received increasing concern.Than single-frequency, double frequency composite ultraphonic irradiation then can increase the cavitation incident significantly, reduces the dead angle that standing wave caused, and improves the sonochemistry yield, and the treatment effect of its generation is much larger than the single-frequency sum that tells on.
China's " applied acoustics " (2007,26 (6) 362-366 pages or leaves) use two low-frequency ultrasonic waves that dye wastewater has been carried out experiment and handled research, obtained good effect, employed reactor is a combination collocation voluntarily in the experiment, promptly at HT-50 type Ultrasonic Cleaners (frequency 40kHz, power 50W, ultrasonic probe diameter 5cm) H66MC type ultrasonic generator (frequency 26.5kHz of stack on the vertical plane, power 0～250W, ultrasonic probe diameter 4cm), carried out simply combining voluntarily up and down, the ultra-sonic generator that has only two different frequencies, structure formation is too simple, can not satisfy the continuous of actual waste water processing, long-term requirement.
The Chinese utility application of application number 200410024548.6 has proposed " method of volatile contaminant in the dual-frequency ultrasonic wave stripping waste water ", wherein, the reactor that uses is provided with the open containers of the ultrasonic transducer of two groups of different frequencies as the vessel bottom, but this has also just increased by one group of high-frequency transverter in the vessel bottom of traditional single-frequency groove type reactor, that is the ultrasonic wave of upwards launching two strands of different frequencies from the open containers bottom that is in same horizontal plane, consider be in the same way double-frequency ultrasound to the influence of water treatment effect, do not relate to of the influence of incorgruous double-frequency ultrasound coupling back, can't maximize the water treatment effect of performance double-frequency ultrasound water treatment effect.
