Abstract
The utility model relates to a non-medium low-temperature plasma pollution purifying apparatus, which is characterized in that plate-shaped metal is used as positive electrodes; a plurality of line-shaped metal wires parallel to the surface of the positive electrode are used as negative electrodes; no medium exists between the positive and the negative electrodes, and low-temperature plasma is generated between through high-voltage discharge. Because no medium exists, a medium breakdown problem does not exist; thus, when the discharge voltage is properly enhanced, the low-temperature plasma with higher electronic density and energy density can be obtained, and the treating effect is enhanced. Because a medium heating problem does not exist, the utilization ratio of energy is largely enhanced. The interphase positive and the negative electrodes are closely assembled together to reduce the volume of the whole purifying apparatus, and thus, the utility model has the advantages of manufacture cost reduction, small ground occupation and convenient installation simultaneously. The interphase positive and the negative electrodes are tightly assembled on the same insulating frame to form an electrode layer. The electrode layer can be independently inserted into, or taken out from the purifying apparatus. One purifying apparatus can be composed of one electrode layer or a plurality of electrode layers. The positive electrodes and the negative electrodes on each electrode layer are respectively connected together. When high voltage is applied to the positive and the negative electrodes, the discharge is uniformly carried out between the positive and the negative electrodes on each electrode layer to form a large-area low-temperature plasma area. When pollution gases orderly flow through the plasma areas on the electrode layers, the molecules of the pollution gases are degraded or oxygenized, or other chemical reaction is generated; thus, the purpose of treating is attained.
Description
Affiliated technical field
A kind of high pressure that utilizes does not have the environmental protection equipment that medium discharge produces low temperature plasma purifying contaminated gas.
Background technology
Recently, increasing people utilizes medium discharge to generate low temperature plasma and administers dusty gas.For example, utilize two medium discharges to generate low temperature plasmas and administered hydrogen sulfide and carbon disulfide or success, utilize two medium discharges to generate low temperature plasmas improvement 3 benzene waste gas and also succeed, promote at present.Utilize single medium discharge to generate low temperature plasma and become a kind of important method of making ozone.
But generate in the method for low temperature plasma at existing pair of medium and single medium discharge, also have many defectives.At first, owing to be subjected to the restriction of medium, discharge voltage can not be too high, otherwise can destroy whole low temperature plasma because of the medium partial breakdown forms arc discharge.This has limited the raising of electron density and energy in the plasma area, thereby causes the regulation effect not good enough.Have again, utilize medium discharge to generate low-temperature plasma and just must adopt the discharge of interchange high-frequency and high-voltage, generate heat, wasted considerable electric energy, reduced the energy utilization rate owing to medium polarizes in alternating electric field repeatedly.Also have, medium discharge mostly adopts the inner and outer pipes structure to make discharge tube, can not closely arrange between each discharge tube, and the volume of discharge tube can not arbitrarily amplify.If reach bigger improvement amount, the volume of whole device and floor space are sizable.These problems fail effectively to be solved so far.
Summary of the invention
In order to overcome the defective that two media and single medium discharge generate the low-temperature plasma body method, the utility model provides a kind of no medium discharge to generate low temperature plasma and administers the contaminated industry exhaust device, it has the electron density height, electron energy is big, the capacity usage ratio height, the characteristics that the plasma zone is big.
The technical scheme that its technical problem that solves the utility model adopts is: adopt the tabular metal as positive electrode, the many wire wires that are parallel to positive electrode surface are as negative electrode, no any medium between the positive and negative electrode, electrion generates low temperature plasma between the positive and negative electrode, contaminated industry waste gas flows through when plasma is regional between the positive and negative electrode, and dusty gas is cleaned.The purpose of this utility model is achieved in that
When applying positive or negative high voltage between the positive and negative electrode, electronics is launched from negative pole, in flying to anodal process, obtains very big energy; Therebetween, electronics constantly bumps with molecule on every side, and gets secondary electron and cation; These secondary electrons and cation bump with molecule on every side again, get more times grade electronics and cation; This process is constantly carried out.Generated a large amount of electronics and cation in region of discharge, their number is identical, is called ion plasma.The molecule and the atom that in ion plasma, also have a large amount of excitation state.When dusty gas flows through between positive and negative electrode, the dusty gas molecule is by electron bombard and cracking, or reacts with oxonium ion, excited oxygen molecule, generates innocuous substance (as carbon dioxide and water), or other chemical reaction takes place generate other innocuous substance, thereby reach the improvement purpose.
The utility model is not owing to exist medium between positive and negative electrode, so there is not the problem of dielectric breakdown, therefore when suitably improving discharge voltage, just can obtain the higher electron density and the plasma of high-energy-density more, thus the raising regulation effect.Owing to there is not the dielectric heat problem, capacity usage ratio also greatly improves.In addition, the just very tabular metal that the utility model adopted can increase the area of positive plate as required, simultaneously the quantity and the length of corresponding increase negative pole metal wire (wire).Positive electrode and negative electrode alternate positive and negative, closely arrangement fit together, and the volume of whole purifier is significantly reduced, and have also reduced cost of manufacture simultaneously.Purifier of the present utility model requires more flexible to the fabricating yard, can vertically install, also can horizontal positioned, as long as blow-off pipe is placed the below of casing, so just can make full use of original place and space.Several positive and negative electrodes are combined, alternate positive and negative is arranged and is fixed on the same insulating support, positive plate is parallel and equidistant, row's wire is arranged as negative pole in the middle of per two positive electrodes, has so just formed one " electrode layer " (seeing schematic diagram two).Can determine the positive and negative electrode number that each " electrode layer " comprised according to the size of exhaust gas flow, and wherein the negative electrode length wiry of the area of each positive plate and each positive plate side and what.According to the requirement to the waste gas purification degree, a device can be made up of one or several " electrode layer ", and waste gas by each " electrode layer ", further improves purifying rate successively.
