Description
Technical field
The present invention relates to the generation of ultrasonic activation and Transfer Technology field, more particularly to one kind efficiently to utilize ultrasonic wave energy
A kind of near sound field ultrasound reactor of amount.
Background technology
With the development of ultrasonic technology, the sonochemistry chemical branch new as one initially forms.Sonochemistry
There is the attention for causing many advanced countries, and put into man power and material and studied.Medium is micro- caused by ultrasonic wave
Grain vibration can produce very big speed and acceleration, the very big energy of media particles can be passed to, when propagating in a liquid
The a series of physical effect such as cavitation effect, activating effect, assembly effect, shearing effect, mechanocaloric effect can be produced, so as to
Ultrasonic wave is set to be provided with scattered, crushing, activate and wait a moment effect, this effect can make only under high-temperature and high-pressure conditions just to enter
The process of row reflection, can be carried out under the conditions of comparatively gentle.Such as using the chemical pollutant in ultrasonic degradation water, it is
A kind of new water technology, it has removal efficiency high, and the reaction time is short, significantly improves the biodegradability of waste water.In recent years
Come, ultrasonic wave is in processing organic wastewater, sludge fermentation and dehydration, drinking water sterilization, sterilization, antiscaling, descaling, Treatment of Sludge, emulsification
Research with emulsification etc. is gone, has been achieved for larger achievement.
But above-mentioned scientific and technological achievement is carried out in laboratory mostly, the popularization and application on industrial flow are also very
It is few.Reason be to lack it is efficient, being capable of mass disposal and the ultrasound reactor that continuously runs.
Ultrasound reactor refers to the container or system for having ultrasonic wave to participate in and being reflected under its effect, and it is to realize
Ultrasonic wave reflection place, though otherwise have how big ultrasonic energy, all do not find a place where one uses one's talents, can not obtain people needs
As a result.
Ultrasonic wave (referring exclusively to ultrasonic wave caused by electromechanical effect) reactor has following several at present：
Groove type reactor：Piezoelectric ceramic ultrasonic transducer is closely attached to the inwall or outer wall of reactor.Transducer passes through
The side wall of reactor radiates ultrasonic wave into reactor.This reactor has that acoustic impedance difference is big, the sound intensity is uneven, tests
Repeatability is bad, can not continuously work etc. deficiency, and current this reactor is mainly used in industry cleaning link.
Sonde-type reactor：Also luffing rod-type reactor is, probe directly invades sounding ultrasonic wave in reaction solution, its sound intensity
Height, energy loss is low, can continuously work, but swept area is small, and emittance is uneven, and treating capacity is small.
Cup type reactor：Made of the good stainless steel material of chemical stability, closely paste disk or folder in the bottom of cup
Core type transducer, ultrasonic wave is radiated into reactor through reactor bottom.Somebody is improved, and will pop one's head in (ultrasonic transformer)
It is also immersed in the reaction solution of reactor.Energy density is high and can adjust, and test repeatability is good.But this reactor only should at present
For in laboratory.
Flow-type reactor：Treatment fluid may make up loop, input power, fluid velocity and the temperature of transducer outside reactor
Degree is controllable, and deficiency is ultrasonic probe because energy is concentrated and seriously corroded, influences service life.
Pipe type reactor：The construction of this reactor is typically all to install piezoelectric ceramic transducer square in the outside of pipe
Battle array, ultrasound are introduced in reaction liquid by tube wall vibration, can exclude the problem of transducer vibrations surface is by corrosion.It is this anti-
Answer device sound field intensity adjustable, the ultrasonic wave for studding with the tube wall ambient radiation of transducer is reflected back again from the cooling pipe outer wall of centre
In treatment fluid.But the ultrasonic wave Net long wave radiation face of this reactor is the inwall of Ultrasonic Radiation pipe, and the energy of outer wall is
It is not utilized, that is, wastes the ultrasonic energy of nearly half.
Parallel-plate near field pattern processor：Processor is made up of the metallic plate of about two radiation ultrasonic waves, and treatment fluid is therefrom
Between coffin flow through, by the strong effect of reverberant field, the sound intensity in coffin is the sound intensity of single metal plate transmitting
More than 2 times.The reactor has been successfully applied to the oil plant that abstracts from crude oil, and handles the field such as oily liq, processing waste water.
But this reactor compatibility that application neutralizes other equipment at the scene is not fine, and occupation of land face is larger, the transducer used
It is more, trouble point is added, in addition, the service life of parallel-plate is restricted.Determined instead by the construction of reactor rectangular channel
Answer the ultrasonication field of device uneven, weak parallactic angle and the dead angle for there are many cavitations in reacting field have that ultrasonic cavitation is uneven to ask
Topic, during large-scale consecutive production, it is possible that the phenomenon of unstable product quality.In addition, in ultrasonic energy
Effective use aspects, there is also the energy that only make use of ultrasonic radiation face one side, and the energy of another side is not utilized.
