Working principle：

Plasma technology for waste gas treatment technology is not the treatment of industrial waste gas washing technology, principle of pollutant treatment: under the influence of external electric field, the medium to produce a large number of articles can discharge the pollutant molecular electron bombardment, ionization, dissociation and excitation, and then triggered a series of complex physical and chemical reaction, make complex macromolecules transformation is a simple small molecule material safety, or toxic and harmful substances into harmless or low toxic harmful substances, so that pollutants can be degraded to remove pollutants, not transfer.

In the process of plasma chemical reaction, the energy transfer in the reaction of chemical energy by plasma is approximately as follows:

(1) Electric field + electron→Energetic electron

(2) High energy electron + molecule (or atom)→Active group (stimulated atom, stimulated radical, free radical)

(3) Active group + molecule (atom)→Composition + heat

(4)Active group + active group→Composition + heat

From the above process can be seen, the first electronic energy from the electric field, the transfer of energy to the atoms or molecules to obtain the excitation or ionization, molecular or atomic energy is excited, while some molecules are ionized, thus becoming active groups; after the collision between these active groups and atoms or molecules, active groups and activities after the formation of stable products and heat group. In addition, high energy electrons can also be trapped by electron affinity substances such as halogens and oxygen, and become negative ions. These negative ions have good chemical activity and play an important role in chemical reactions. The technology of dealing with industrial waste gas by plasma waste gas treatment is not washing technology, but it is the direct breakdown and direct bombardment of pollutants by high-energy plasma, which breaks the molecular chain, not the transfer of pollutants.

Application of low temperature plasma technology in environmental engineering:
Low temperature plasma technology is mainly used in the waste gas treatment in the petroleum, pharmaceutical, paint, printing and coating industries. A broad range of applications, the basic component is not affected by the temperature and the concentration of pollutants, odor and foul smell has decomposition effect, the removal rate of 80-98% of the foul smell, odor gas concentration after treatment to reach the national standard.

Technical characteristics:
The application of low temperature plasma waste gas treatment technology in waste gas treatment has the advantages of good treatment effect, low operating cost, no two pollution, stable operation, simple operation and management, and instant operation. Important characteristics: Taking non methane total hydrocarbons as an example, the removal rate of non methane total hydrocarbons may be only 45%, but the removal rate of odor and odor is 90%. This is because after the treatment of non methyl a, some molecules become small molecules, and when chromatography is used, it still shows non methane total hydrocarbons. The high removal rate of odor and odor indicates that more than 90% of the pollutants have been decomposed, because the decomposed substances also have some peculiar smell.

Working principle：

The high energy and high ozone ultraviolet light irradiation UV emissions, industrial emissions of ammonia, such as cracking of trimethylamine, hydrogen sulfide, dimethyl sulfide hydrogen, methyl mercaptan and dimethyl sulfide, butyl acetate, ethyl acetate, two methyl two sulfur, carbon disulfide and styrene, H2S, sulfide VOC, benzene, toluene, benzene, methyl two. UV ultraviolet light makes organic or inorganic macromolecule odor compounds molecular chain, under the high-energy ultraviolet beam irradiation, degrade into low molecular compounds, such as CO2, H2O and so on.

The reaction in the above formula, the decomposition of hydroxyl radicals in the air by using high energy and high ozone UV ultraviolet light (OH) and superoxide anion free radical (O2-) has a strong oxidation, both in the gas phase and in liquid phase, can be some organic or inorganic substances should be free of oxygen. Oxygen carrying electron positron imbalance so it needs to combine with oxygen molecules, and the production of ozone. As is known to all, ozone has a strong oxidizing effect on organic compounds and has an immediate effect on industrial waste gases and other irritating odors. Using high-energy UV beams to split the molecular bonds of bacteria in malodorous gas, destroy the nucleic acid (DNA) of bacteria, and then oxidize by ozone to completely remove odor and kill bacteria.

Scope of application:
Suitable for oil refineries, rubber factory, chemical factory, pharmaceutical factory, sewage treatment plants, garbage transfer stations, food waste treatment plant, feed factory, printing and dyeing, spraying plant and other pollution source malodorous gas deodorization purification.

Technical characteristics:
Non-toxic, without any side effects, completely beyond the traditional ozone and other air purifiers, can be in the presence of the presence of continuous sterilization, can be widely intercepted and killed in the air of various bacteria. Effective elimination of pollution, harmful gases, odor.
