At present, the gaseous waste gas mainly comprises nitrogen-containing organic waste gas, sulfur-containing waste gas and hydrocarbon organic waste gas. (1) A nitrogen-containing waste gas. Such exhaust gas causes damage to the air components, changing the gas composition ratio. In particular, combustion of petroleum products is a huge amount of combustion of petroleum products in industrial production, and the content of nitrides in the petroleum products is large, so that exhaust gas contains a large amount of nitrogen oxides, and if the exhaust gas is discharged into the air, the content of nitrogen oxides in the air is increased, thereby affecting the atmospheric circulation. (2) Sulfur containing waste gas. Sulfur-containing exhaust gases pose a direct hazard to the living environment of people, as they combine with water in the air to form acidic species that cause acid rain. Acid rain can cause damage to plants, buildings and human health, and particularly can affect the respiratory tract of people. In addition, the method can also affect soil and water sources and cause secondary pollution. (3) A hydrocarbon organic exhaust gas. This type of exhaust gas, collectively referred to as hydrocarbons, is an organic compound, consisting primarily of carbon and hydrogen atoms. The diffusion of such waste gases into the atmosphere causes a series of problems and effects on the destruction of the ozone layer. For example, ozone depletion aggravates ultraviolet radiation, which can cause damage to human skin and cause various health problems. In addition, changes in the degree of ultraviolet irradiation can also have an effect on the ecosystem and on the climate.

Further, the keypad section 4 further includes a defogger 13, a filter plate 14, and a second fan 15, which are sequentially disposed. The second fan 15 drives the exhaust air into the main body 1.
Furthermore, a water mist opening 16 is further formed in the main body 1 near the air inlet, and water mist is sprayed through the water mist opening 16.
furthermore, the catalytic region 5 is further provided with a second air inlet 17, and the second air inlet 17 is arranged to help the first fan 10 change the air flow, so that the air flow drives the particles to pass through the one-way air plate 12 to treat the exhaust gas.

The low-temperature plasma is a substance fourth state following solid, liquid and gaseous states, and when an external voltage reaches the breakdown voltage of gas molecules, a mixture comprising electrons, various ions, atoms and free radicals is generated. In the low-temperature plasma discharge process, although the electron temperature is high, the heavy particle temperature is low, and the whole system is in a low-temperature state, which is called low-temperature plasma. Energy transfer is generally that electrons obtain energy from an electric field, the energy is converted into internal energy and kinetic energy of molecules through collision, the molecules obtaining the energy are excited, part of the molecules are ionized, and the activated particles collide with each other to cause a series of complex physicochemical reactions. Because of the abundant active particles such as ions, electrons, excited atoms and molecules, free radicals and the like in the plasma, conditions are provided for processing the odor substances. It is based on the interdiscipline of discharge physics, discharge chemistry, reaction engineering.
The oxygen molecules of the electrons in the domain region become positive oxygen ions (O 2 +), and the released electrons are combined with another neutral oxygen molecules to become negative oxygen ions (O 2 -), so that the two-stage differentiation of the oxygen ions and the adsorption of the neutral oxygen molecules form oxygen polymeric particle groups such as O 2 +, O 2 -, O 2 and the like, and the oxygen ions have strong oxidizability and can oxidize and decompose harmful components in the polluted air into harmless products and water in nanoseconds or shorter time.
Under the high-energy action of the high-energy low-temperature plasma, a large amount of ions, free radicals and hydroxyl radicals are generated, and the generation mechanism is as follows:
O2+e（3.6eV） → •O+O
H2O+e(5.09eV) → •OH+H-
O+•OH →•OH2
the research shows that: the oxidation potential (2.8 eV) of OH, the active radical, is 35% higher than the ozone oxidation potential (2.07 eV) which is very oxidizing. The reaction speed of OH radicals with organic substances is higher by several orders of magnitude. Moreover, the OH radicals are not selective in oxidizing pollutants and can initiate chain reactions that directly oxidize most of the harmful substances in the polluted air to carbon dioxide and water or minerals. The action mechanism is as follows:
H2S+•OH → HS+H2O
HS+O2+O2+ + O2- → SO3+H2O
H2S+e(13.6eV)→H2+S
NH3•OH → NH2+H2O
NH2+O2+O2+ + O2- → → NOX+H2O
NOX+NH3 →N2+H2O
CH2O+O2+ + O2- +•OH → H•COOH+H2O
CxHy + ( x + y/4 )O2 --→ xCO2 +y/2H2O
CxHyOz + ( x + y/4 - z/2 )O2 --→ xCO2 +y/2H2O
practice proves that most harmful substances in polluted air with certain concentration can be oxidized and decomposed in a short time. High treatment efficiency, can effectively remove specific pollutants such as hydrogen sulfide (H2S), ammonia (NH3), methyl mercaptan and the like, and various peculiar (smelly) odors, and has the effect of 85-95 percent. Because the ion energy generated by the high-energy ion device can not completely treat the waste gas with high bond energy, long molecular chain and unstable gas amount, a jet flow cold particle exciter is needed to be added to improve the treatment efficiency, thereby achieving the purposes of air purification and ultralow emission.
The photocatalyst is a photo-catalyst (catalyst), which is a general name of a photo-semiconductor material with a photocatalytic function represented by nano-scale titanium dioxide, and is an ideal material for treating environmental pollution internationally, the photocatalyst reaction mechanism is that when nano-scale titanium dioxide ultrafine particles are irradiated by ultraviolet rays with the wavelength of below 388nm, the nano-scale titanium dioxide ultrafine particles are excited to generate electrons and hole pairs, namely photo-generated carriers, by absorbing light energy, then the photo-generated carriers rapidly migrate to the surfaces of the photo-generated carriers and activate adsorbed oxygen and moisture to generate active free hydroxyl radicals (.OH) and active oxygen (.O), and the photo-oxidation reduction function is strong, when pollutants and bacteria adsorb the surfaces of the photo-generated carriers, a chain type degradation reaction is generated, various organic compounds and partial inorganic substances can be oxidized and decomposed, cell membranes of the bacteria and proteins of solidified viruses can be damaged, the bacteria can be killed and the organic pollutants can be decomposed, and most of the organic pollutants can be decomposed into pollution-free water (H 2 O) and carbon dioxide (CO 2), so the photocatalyst has extremely strong functions of sterilization, mildew prevention, self.
The cold particles are generated by a cold particle generator, the generated cold particles can break molecular bonds of the passing exhaust gas within nanosecond level, small molecules or ions with broken bonds reach the surface of a catalyst and are quickly oxidized into non-toxic and harmless substances or CO 2 and H 2 O under the action of the catalyst, the bond energy of benzene and the bond energy of ammonia are large, the treatment efficiency of the high-energy ion purifier cannot reach 80%, and the cold particle technology can reach and exceed the energy required by broken bonds at low temperature (40-60 ℃).
The catalytic plate is catalytic enzyme prepared by environment-friendly, nontoxic and harmless materials, and is mainly used for improving catalytic oxidation efficiency, reducing energy consumption and converting polar dirt and better improving the safety performance of equipment.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
