Embodiment
As shown in drawings, the utility model comprises: the bottom in reaction hood 6 is equipped with insulator foot 3 from bottom to up successively, be equipped with down big little on the insulator foot 3 monosymmetric insulation columns 4 respectively, the cutter type that links to each other with high-voltage power supply 8 divides interdigitated electrode 5 and forms starting the arc end 11, there is the waste collection groove 9 that links to each other with wastewater trough 7 at insulator foot 3 middle parts, waste collection groove 9 notches are equipped with the nozzle 10 that is fixed on the insulator foot 3, gas sampling mouth 15 is equipped with on the top of reaction hood 6 successively, gas exhaust duct 16, the gas exhaust duct 16 outer watercooling jackets 17 that link to each other with fluid collection vials 13 with catheter 14 that are equipped with, the waste water of the pressurized air of air compressor 1 and wastewater trough 7 inserts nozzle 10 together by conduit respectively.
Said nozzle 10, its nozzle diameter are 1～5mm, and model can adopt SUJ11, SUJ12 etc.
The minimum place of distance is 2～5mm between cutter type bifurcated two electrodes 5 at said starting the arc end 11 places.
The plasma method of wastewater treatment is to connect 10KV ac high voltage source 8, waste water solution passes through the sucking-off of gas injection from aqua storage tank 7, the waste water of the pressurized air of air compressor 1 and wastewater trough 7 sprays the speed of air-water mixtures greater than 10m/s by air atomization nozzle 10, generation is less than 15 microns waste water atomizing particle, waste water water smoke promotes the mobile downstream gliding arc discharge that produces of slip electric arc 12 that starting the arc end 11 forms, under normal pressure, obtain nonequilibrium plasma, produce ozone, ultraviolet ray, high-energy electron, electrolytic action, OH and O isoreactivity particle directly act on processed waste water, realize online discharge process, and make waste water change harmless object into.The time decision that treatment time is mainly stopped in the gliding arc discharge zone by water smoke, the water smoke flow is regulated by nozzle 10.Sample by gas sampling mouth 15, tail gas 18 is discharged by gas exhaust duct 16, and under the cooling of watercooling jacket 17, steam is condensed into liquid, flows into reservoir 13 by catheter 14.
Method of wastewater treatment described in the utility model and device can play following effect:
In the gliding arc discharge plasma body, every slip electric arc is exactly a plasma channel, will produce particles such as a large amount of high-energy electrons, ion, free radical etc. under the high temperature in plasma channel, the high pressure, as following each reaction formula:
High-energy electron and living radical (O, OH, e
Aq -, HO
2 -Deng) will bombard and the oxidation of organic compounds molecule, making its eventual degradation is CO
2And H
2Innoxious substances such as O.Simultaneously, because the generation of high temperature, high pressure plasma passage, ((3～10Gpa), make to cause following several physical-chemical reaction process in the solution of plasma channel field and external region thereof: ozone oxidation, ultraviolet photodissociation, electrohydraulic cavitation degradation and supercritical water oxidation are degraded for wavelength 75～185nm) and huge impact ripple to be accompanied by the intensive UV-light.People such as the Wei Erbai of California, USA technical institute adopt liquid electricimpulse plasma body P-Chlorophenol, and organism such as TNT carry out degradation experiment.Through 1 fen clock time, (each discharge power consumption 4～7KJ) made these several organic clearances reach 99% to about 200 times high-energy discharge.
After plasma channel forms, because it has high temperature, it just looks like a light source that outwards gives off strong UV-light, institute's radiating UV-light is absorbed by the atomizing droplet around the plasma channel at once, impel the dissolved oxygen in the water to produce excited oxygen atom and organic molecule effect, reach the purpose of oxidation of organic compounds.
Because the enormous impact pressure wave that the outwards rapid expansion of plasma channel causes by means of liquid electricity cavitation (bubble) effect, directly acts on organic molecule it is carried out the DeR of pyrolysis and free radical.
Because the atomizing droplet transmission towards periphery of the heat of plasma channel has caused the generation of many steam bubbles.In these bubbles, the supercritical water that is enough to form transient state that temperature and pressure is high.Therefore, organism in the bubble and oxygen and supercritical water dissolve each other fully, make the spontaneous beginning oxidation of organism.
In sum, the organic process of gliding arc discharge plasma degradation is quite complicated, is a mutual alternative process of multiple oxidation.
