The application of plasma photolysis purification equipment in the treatment of odorous gases has the advantages of good treatment effect, low operating cost, no secondary pollution, stable operation, easy operation and management, and immediate use.

Compared with the commonly used odor gas treatment methods in China, it has the following characteristics:

① Dielectric barrier discharge generates high electron energy and high low-temperature plasma density, reaching 1500 times that of commonly used plasma technology (corona discharge), and can interact with almost all odorous gas molecules;

② Technical reaction, the gas passing through the reaction zone at a speed of 3-15 meters per second achieves a good treatment effect, which is difficult to achieve with other technical gases passing through the reaction zone at a speed of 0.01 meters per second;

③ The gas passage section is entirely made of materials such as ceramics, quartz, stainless steel, etc. The electrodes do not come into direct contact with the exhaust gas, fundamentally solving the corrosion problem of low-temperature plasma technology equipment; Other technologies involve direct contact between gas and electrodes, which can cause severe corrosion within 3 months or 1 year. Even if the gas passing through is not corrosive, the generated ozone can corrode the electrodes;

④ The host is a complete industrial waste gas treatment device, equipped with a tower in front, which can remove dust and moisture from the waste gas and is easy to operate;

⑤ High degree of automation, equipment can be started and stopped as needed, and for some chemical production discontinuities, it can be started during production and stopped during non production intervals, saving a lot of energy;

⑥ The operating cost is relatively low, saving 5-8 times the operating cost compared to commonly used regenerative combustion furnaces RTO. The operating cost per cubic meter of gas is only 0.3-0.9 cents, and some exhaust gases can be diluted with air and treated with technology;

⑦ Widely applicable, basically unaffected by temperature and pollutant components, it has a good decomposition effect on the odor concentration of foul odors. The removal rate of foul odors reaches 80%, and the concentration of treated gas odor meets the standard;

⑧ The technology for treating industrial waste gas is not water washing technology, but rather the direct breakdown and bombardment of pollutants through plasma, causing molecular chain breakage, rather than the transfer of pollutants;

⑨ Important feature: Taking non methane total hydrocarbons as an example, when detected by chromatography, the removal rate of non methane total hydrocarbons may only be 45%, but the removal rate of foul odors is high. This is because after processing, some molecules of non methane total hydrocarbons become small molecules, and when detected by chromatography, they still appear as non methane total hydrocarbons; The high removal rate of foul odors indicates that the pollutants have actually decomposed, as some of the decomposed substances also have odors;

⑩ Solved the world problem of dioxins, which contain chlorine and are mostly electrophilic groups that are easily bombarded by electrons.

Principle of action of plasma photolysis purification equipment:

Low temperature plasma is the fourth state of matter after solid, liquid, and gas. When the applied voltage reaches the discharge voltage of the gas, the gas is broken down, producing a mixture including electrons, various ions, atoms, and free radicals. During the discharge process, although the electron temperature is high, the temperature of heavy particles is low, and the entire system exhibits a low-temperature state, hence it is called low-temperature plasma. Low temperature plasma degradation of pollutants utilizes the interaction between these active particles such as electrons and free radicals and pollutants in exhaust gas, causing pollutant molecules to decompose within a certain period of time and undergo various subsequent reactions to achieve the goal of pollutant degradation.

The substances rich in the plasma reaction zone, such as electrons, ions, free radicals, and excited state molecules, can react with pollutants in the exhaust gas, causing the pollutants to decompose and undergo various subsequent reactions to achieve the purpose of explaining pollutants. Compared with the low-temperature plasma technology generated by traditional corona discharge, the discharge density of plasma technology is 1500 times that of corona discharge, which is the reason why traditional low-temperature plasma technology has failed to treat industrial waste gas.
