[description of drawings]
It shown in the accompanying drawing 1 the apparatus structure synoptic diagram of the specific embodiment of the invention.
Be along the sectional view of AA direction shown in the accompanying drawing 2 in the accompanying drawing 1.
Be along the sectional view of BB direction shown in the accompanying drawing 3 in the accompanying drawing 1.
[embodiment]
Next introduce the embodiment of steam blended method of wastewater treatment of the present invention and device in conjunction with the accompanying drawings in detail.
Be the apparatus structure synoptic diagram of the specific embodiment of the invention shown in the accompanying drawing 1, comprise: plasma generator 1 has inlet mouth 11, air outlet 12 and humidifier 13; Blower fan 2 comprises inlet mouth 21 and air outlet 22; Steam mixing column 3 has inlet mouth 31, air outlet 32, water-in 33 and water outlet 34.Described device also comprises backflow gas circuit 4, and backflow gas circuit 4 is arranged on the air outlet 32 of steam mixing column 3 between plasma producing apparatus 1 inlet mouth 11.
Said apparatus is when work, and the gas that at first will purify usefulness feeds in the middle of the plasma producing apparatus 1, and the gas that purifies usefulness contains oxygen, so that can form atomic oxygen and the hydroxyl with strong oxidizing property after entering plasma producing apparatus 1.Can adopt air in the present embodiment.
Shown in the accompanying drawing 2 be in the accompanying drawing 1 along the sectional view of AA direction, showed the internal structure synoptic diagram of plasma producing apparatus 1, comprise anodal 101, negative pole 102 and be arranged on emission thorn 103 on anodal 101.The gas that feeds plasma generator 1 can partial ionization become plasma state under the effect of such plasma producing apparatus, wherein oxygen is ionized to atomic oxygen, if communicate as gas in contain water vapor, can also further form hydroxyl, two kinds of materials of above-mentioned atomic oxygen and hydroxyl all have strong oxidizing property.Certainly, though plasma body is not the complete ionization of gas to feeding, and just partial ionization, but experiment shows, because the oxidisability of atomic oxygen and hydroxyl is very strong, therefore for follow-up step of purifying waste water, partial ionization can have been satisfied the demand of sewage purification.The electricity input parameter of regulating plasma producing apparatus 1 can improve it to ionisation of gas efficient.
Gas after plasma producing apparatus 1 is handled enters blower fan 2.The inlet mouth 21 of blower fan 2 and air outlet 12 UNICOMs of plasma generator 1, inlet mouth 31 UNICOMs of air outlet 22 and steam mixing column 3, the gas delivery that contains atomic oxygen and hydroxyl that plasma producing apparatus 1 can be formed is among steam mixing column 3.Because atomic oxygen and hydroxy chemical character that gas forms after plasma treatment are active, in order to guarantee that these active substances have enough ratios can enter steam mixing column 3 rather than consume on the path that transports, so need blower fan 2 to improve gas from the velocity of flow of plasma producing apparatus 1 to steam mixing column 3.
Gas after the ionization is entered after the steam mixing column 3, will flow along opposite direction subtend, mix fully obtaining with the sewage that enters steam mixing column 3 equally.Specifically, steam mixing column 3 comprises inlet mouth 31, air outlet 32, water-in 33 and water outlet 34.Inlet mouth 31 is positioned at tower bottom, and link with the air outlet 22 of blower fan 2, be used for the gas after the ionization is fed steam mixing column 3, and the air outlet is positioned at the top of steam mixing column 3, the gas that such being provided with guaranteed to feed steam mixing column 3 is mobile from bottom to top.And the water-in 33 of steam mixing column 3 is positioned at the top of tower and water outlet 34 is positioned at tower bottom, and such being provided with guaranteed that the flow direction of sewage is to flow to the bottom from top.Pending sewage flows into and flows out from water outlet 34 from water-in 33, thus can with the gas thorough mixing after the ionization.Sewage has the atomic oxygen of strong oxidizing property and the material generation oxidizing reactions such as organic matter in hydroxyl and the sewage with after gas after the ionization mixes in the gas, can reduce the chemical oxygen demand (COD) of sewage, reaches the purpose of purifying waste water.
Accompanying drawing 3 is accompanying drawing 1 sectional views along the BB direction, has showed the internal structure of steam mixing column 3.Steam mixing column 3 can further include filler 35, the use of filler 35 can slow down the speed of passing through of gas and sewage, especially can reduce sewage speed by steam mixing column 3 under action of gravity, and sewage can also increase the surface-area of sewage attached to the surface of filler 35, thereby makes itself and the gas thorough mixing that feeds.
For polluting comparatively serious sewage, said apparatus may can not be purified to it degree that meets discharging standards fully.In this case a plurality of said apparatus can also be set further, and the steam mixing column 3 in each device is cascaded, sewage is purified step by step.
The previously described preferred implementation of the present invention is in order to illustrate and to describe purpose of the present invention.Should not limit the present invention within the disclosed content, also might be by coming from the enlightenment in the above-mentioned record content and practice of the present invention being obtained adjustment of the present invention and change.Therefore, the given embodiment of the present invention is not restriction but explains technical spirit of the present invention that protection scope of the present invention is not limited by embodiment.Protection scope of the present invention should be determined by claim, is equal to replacement and also should be considered as not exceeding protection scope of the present invention of the present invention.
