Description
Technical field
The present invention relates to the sterilizing field of ultrasonic wave and ozone, more particularly to a kind of going out based on ultrasound-enhanced ozone oxidation
Bacterium device.
Background technology
For ozone because having very strong oxidability (oxidation-reduction potential can reach 2.07V), the reaction time is short, can aoxidize water
The advantages that middle most of organic matter, oxidation can also often be passed through by the core technology as high-level oxidation technology (AOPs), ozone
Cell membrane is destroyed, there is very strong sterilizing ability.
Ultrasonic wave can produce a series of effect in its communication process, when the ul-trasonic irradiation of some strength is in liquid
When, a large amount of cavitation bubbles can be produced, and change with sound wave and change size and moment vanishes and forms cavitation phenomenon.Cavitation can
High temperature (5000k) high pressure (5.0x104kPa) and Strong shear power are produced to microbial cell individual moment, are allowed to inactivate.
Although single ozone process can realize sterilization, the sterilization effect of ozone is decided by the gentle hydrosphere of its concentration
Face, the ozone of high concentration need the equipment of complicated and high operating cost to realize, and due to the extremely strong oxidation of ozone with
The characteristics of non-targeted effect, accessory substance is easily formed so as to cause secondary pollution, therefore needed during using ozone sterilization
Solve the problems, such as how to reduce the ozone of effusion, how to increase mass transfer interface.
Common ultrasonic reactor has a cleaning groove type reactor and luffing rod-type reactor, pending liquid in groove type reactor
Residence time is grown, and reactor volume is larger, easily forms short stream and dead band, can not obtain the higher sound intensity, and sound wave reflection is serious；Become
Width rod-type reactor action scope is small, and detecting head surface is perishable because of collection cavitation.
The sterilization effect of ultrasonic reactor is decided by the energy output size (sound field intensity) and cavitation (air pocket) of its sound wave
The space size (acoustic field uniformity) of effect.High frequency ultrasound (>200kHz) due to technical problems such as power supply, shake plates, equipment is expensive,
Stability is relatively low, no image of Buddha low frequency ultrasound (<High-power equipment 200kHz) is made in industrialization like that, although low frequency ultrasound is straight
It is weak to connect oxidability higher-frequency ultrasound, but the output of the energy of high-strength sound field and high performance-price ratio is especially suitable for being combined other oxidation technologies
(such as ozone), which is realized, strengthens bactericidal effect.
Pre-existing reactors between pulling flow type (Plug flow) reactor and complete mix flow (CSTR),
On the premise of realizing high efficient gas and liquid mass transfer and liquid-liquid transfer, how to reduce reactor residence time, dead band and short stream is reactor
The main target of design.Design difficulty for ozone reactor is to improve gas-liquid mass transfer efficiency, and increases ozone simultaneously with going out
Zoopagales target contact probability；And it is the homogenization of sound field for the design difficulty of ultrasonic reactor, and sterilize target and cavitation
The contact probability in domain.
