Technical field
The invention belongs to organic water pollution degradation technique field, refers in particular to the vortex sky in a kind of organic water pollution degeneration system
Makeup is put.
Background technology
Now with quickly propelling for China's process of industrialization, substantial amounts of life, industrial wastewater are generated.Many waste water do not have
Have and be directly discharged in river through necessary process, to ecological environment very big execution is brought.At this stage with regard to dirt
The treatment technology of water substantially can be divided three classes, i.e. physical treatment process, method of chemical treatment and biological treatment.Wherein physical treatment
Relatively common in method is grid retention method, the sedimentation method, Bubble-floating Method and Filtration etc..This kind of method treatment effeciency is low, during process
Between it is long, but cost of investment is relatively smaller.Chemical treatment method includes neutralization, electrolysis, oxidoreduction, ion exchange etc., main
It is applied to process industrial wastewater.This kind of method efficiency high, but it is of a relatively high to there is also cost, it is understood that there may be secondary pollution etc.
Problem.Bioremediation is mainly aerobic method and anaerobic process, and this kind of method is comparatively more environmentally friendly, but process time compared with
Long, processing scheme can also be protected from environmental under partial picture.
Cavitation is the hydraulics phenomenon of very disruptive, and its harm is related to small-sized hydraulic and large hydraulic engineering, together
Cavitation, Cavitation is the difficult problem of long-standing problem hydraulic expert.To cavitation phenomenon, first physics is retouched from before more than 100 years
State beginning, negative effect effect of the people just always to cavitation is paid close attention to, carry out prediction for cavitation destruction, pre-
Anti- research work, and obtain certain achievement.But, cavitation also has its positive influences effect, but ignored always.Cavitation is stream
A kind of distinctive phenomenon in body, crumbling and fall with cavitation bubble when cavitation occurs, moment can discharge substantial amounts of energy, and utilizing should
Energy can realize the invigoration effect to chemistry, physical process, reach potentiation, energy-conservation, the effect of consumption reduction.Local caused by cavitation
The extreme environments such as High Temperature High Pressure can produce substantial amounts of free radical, and free radical further reacts with Organic substance, causes degraded even
Mineralising.Therefore the characteristics of the method has widely applicable, oxidation efficiency is high, all there is good oxidation to imitate each type organic
Really.Theoretical foundation can be provided to carry out energy-efficient organic water pollution degraded using cavitation effect, be provided to researchers
One brand-new thinking.Because the technology has low energy consumption, environmentally friendly non-secondary pollution, device manufacturing process is relatively easy, processes
Efficiency is higher.Deng product design maturation after can comprehensively be promoted, so as to contribute to advance efforts at environmental protection development.

In such scheme, the first through hole is twist uniformly arranged on the tube wall of the water inlet pipe.
In such scheme, the first through hole has eight, is arranged on the tube wall of the water inlet pipe in a row per four.
In such scheme, the intracavity bottom in the vortex storehouse is additionally provided with cavitation block, is sequentially provided with the cavitation block mutually
First conical surface, second conical surface and the vertical plane for connecting, the taper of first conical surface is more than the taper of second conical surface, described
Just to first conical surface and the central axis of second conical surface, the bottom of the cavitation block is provided with the second through hole to water inlet pipe,
Second through hole is connected with the apopore.
In such scheme, second through hole is the through hole of tapered cross-section, and the top pore radius of second through hole is big, bottom
Portion's pore radius is little.
In such scheme, block is additionally provided with immediately below second through hole, the block is arranged on the apopore
Centre.
The device is distinctive a kind of phenomenon in fluid for cavitation using theoretical principle, with cavitation bubble when cavitation occurs
Crumble and fall, moment can discharge substantial amounts of energy, using the energy invigoration effect to chemistry, physical process can be realized, reach
To potentiation, energy-conservation, the effect of consumption reduction.The extreme environment such as localized hyperthermia's high pressure can produce substantial amounts of free radical caused by cavitation, from
Further reacted with Organic substance by base, cause degraded even mineralising.
Beneficial effects of the present invention:(1)When the organic sewage of certain pressure and flow velocity passes through water inlet pipe, arranged by spiral type
There is first time cavitation in the first through hole of row;There is the organic sewage of cavitation by first conical surface, second conical surface on cavitation block
Afterwards because the change of water velocity further speeds up cavitation, the organic sewage with cavitation bubble is impacted after the discharge of the second through hole
The baffle plate of lower section causes cavitation to crumble and fall, and strengthens cavitation effect, so as to organic substance in sewage of effectively degrading.(2)Whole device
Simple structure, by cavitation effect the fast degradation of organic sewage is accelerated, and decontaminates efficiency high.
