[embodiment]
Next introduce the embodiment that employing lower temperature plasma technology described in the utility model carries out the device of treatment of Organic Wastewater in conjunction with the accompanying drawings in detail.
Be the apparatus structure synoptic diagram of present embodiment shown in the accompanying drawing 1, comprise: a negative plate that is obliquely installed 10; One is arranged on the positive plate 20 of negative plate 10 tops, and a plurality of emissions thorns 21 are being set on the surface of the positive plate 20 of negative plate 10; One is arranged on the tank 30 of negative plate 10 higher sides, and the water outlet 31 of tank 30 is towards the surface of negative plate 10; The one power supply (not shown) that is connected with negative plate 10 electricity with positive plate 20, with produce can activated plasma voltage.This device further is provided with following selectable unit (SU): one is arranged on the inclination adjusting device 40 of negative plate 10 higher ends; One water reservoir 50; One water pump 60; One is arranged on the upflow tube 70 between tank 30 and the water reservoir 50.
Accompanying drawing 2 is accompanying drawing 1 described device synoptic diagram after having installed loam cake 90 additional.The positive plate 20 and the negative plate 10 of device are sealed in loam cake 90 inside, can prevent that like this plasma body is directly exposed to the danger that causes electric shock in the environment.
Accompanying drawing 3 is accompanying drawing 2 sectional views along the AA direction, from then on can see a plurality of porcelain insulators 80 in the sectional view.Porcelain insulator 80 is used for positive plate 20 liftings are fixed on the upper surface of negative plate 10, and can guarantee that between negative plate 10 and the positive plate 20 be insulating.Accompanying drawing 3 is the structural representation shown in the respective figure 1 along the section of BB direction.
With reference to figures 1 through accompanying drawing 3, this device provides a surface that tilts by the negative plate 10 that is obliquely installed.When filtering sewage, sewage is flowed out from the water outlet of tank 30, on the surface that tilts, form moisture film.Owing to be provided with the positive pole that has emission thorn above moisture film, and this inclined surface is as negative pole, by power supply between positive pole and negative pole, apply can activated plasma voltage, promptly can form plasma body.Water molecules (H in the sewage
2O) under the effect of plasma excitation condition, can decomposite a large amount of OH, HO
2, free radical and the extremely strong O of oxidisability such as O
3, these materials all have strong oxidizing property, so the organism in the sewage etc. can be by rapid oxidation under the effect of impurity at plasma body, thereby reach aim of purifying.Here adopt the high energy particle in the low-temperature plasma to replace chemical agent of the prior art with strong oxidizing property, remove organic content in the decontaminated water by strong oxidizing property, the entire treatment process is consumed power only, therefore is a kind of cheap waste disposal plant that cleans.
This device further is provided with following selectable unit (SU)s.
One is arranged on the inclination adjusting device 40 of negative plate 10 higher ends, can adjust the height of negative plate 10 higher ends, thereby adjusts the flow velocity of the inclined degree of negative plate 10 with control surface.The height of rising inclination adjusting device 40 can improve the inclined degree of negative plate 10.Described inclination adjusting device 40 can adopt common lifting device in any mechanical field, for example can be that an end is fixed on negative plate 10 back sides, and the connecting rod that the other end can move up and down along a draw-in groove of vertical negative plate 10, also can be have screw thread can be along push rod that moves up and down perpendicular to negative plate 10 directions etc.Inclination adjusting device 40 also can be arranged on the lower end of negative plate, can improve the inclined degree of negative plate 10 by the height that reduces this end.Obviously, the inclined degree of negative plate 10 is more little, and the speed of current is just slow more, and is also just high more to the elite efficient of sewage, and the purpose of therefore adjusting negative plate 10 thickness is to adjust the degree of purification of sewage.The inclined degree that can reduce negative plate 10 for messy sewage is with the raising degree of purification, and for relative not too dirty sewage, the inclined degree that can suitably increase negative plate 10 is to improve the water purification amount of unit time.
One water reservoir 50, the low side UNICOM of the water-in of this water reservoir 50 and negative pole 10 plates; One water pump 60,60 water-ins of water pump are connected to water reservoir 50, and water outlet is connected to tank 30, is used for water reservoir 50 through carrying out circularly purifying in the water introducing tank 30 that purifies.Obviously the volume of water reservoir 50 is more preferably greater than the volume of tank 30, can hold more recirculation water.
Under the situation that is provided with water reservoir 50 and tank 30, upflow tube 70 between tank 30 and water reservoir 50 can also optionally be set, the maximum of upflow tube 70 corresponding tank 30 in the position of tank 30 split sheds allows water level, and the effect of this upflow tube 70 is to prevent that tank 30 median water level from overflowing.In case the water of tank 30 is higher than the maximum water level that allows, the water that exceeds will be back to water reservoir 50 by this upflow tube 70.Because water pump 60 can not be in full accord to the drainage speed of the water storage speed of tank 30 and tank 30, in case water pump 60 is slightly larger than tank 30 water displacement to the pondage of tank 30, this upflow tube 70 can prevent that water stopping trough overflows, and avoids the maintenance personnel at any time tank 30 to be monitored.
This device can also comprise that one is arranged on the baffle plate (not shown) at tank water outlet place.The lower end of described baffle plate is surperficial parallel with negative plate, and can move up and down, and described baffle plate can be adjusted the aquifer yield of tank, thereby is adjusted at the thickness of the moisture film that negative plate 10 surface currents cross.Obviously, water film thickness is thin more, and is high more to the elite efficient of sewage, and the purpose of therefore adjusting the thickness of moisture film is to adjust the degree of purification of sewage.The thickness that can reduce moisture film for messy sewage is with the raising degree of purification, and for relative not too dirty sewage, the thickness that can suitably increase moisture film is to improve the water purification amount of unit time.
The previously described preferred implementation of the utility model is in order to illustrate and to describe the purpose of this utility model.The utility model should be limited within the disclosed content, also might be by coming from the enlightenment in the above-mentioned record content and practice of the present utility model being obtained adjustment of the present utility model and change.Therefore, the given embodiment of the utility model is not restriction but explains technical spirit of the present utility model that protection domain of the present utility model is not limited by embodiment.Protection domain of the present utility model should be determined by claim, is equal to replacement and also should be considered as not exceeding protection domain of the present utility model of the present utility model.
