The low-temperature plasma exhaust gas treatment equipment body is the fourth state after the solid state, the liquid state and the gaseous state. When the applied voltage reaches the discharge voltage of the gas, the gas is punctured to produce a mixture including electrons, various ions, atoms and free body. Discharge process although the electronic temperature is high, but the heavy particle temperature is very low, the whole system showed low temperature state, so called low temperature plasma. Low temperature plasma degradation of pollutants is the use of these high-energy electrons, free and other active particles and pollutants in the role of pollutants, so that pollutants in a very short period of time decomposition, and the subsequent reaction to achieve the degradation of pollutants purpose. (Note: low temperature plasma relative to high temperature plasma, is running at room temperature.)
Low temperature plasma exhaust gas treatment equipment Body reaction area is rich in very high substances, such as high-energy electrons, ions, free and excited molecules, pollutants in the exhaust pollutants can react with these substances with high energy, so that pollutants in the pole Short time within the decomposition, and follow-up of various reactions in order to achieve the purpose of explaining pollutants. Compared with the traditional corona discharge situation of low temperature plasma technology compared to the plasma technology discharge density is corona discharge 1500 times, which is the traditional low-temperature plasma technology to deal with 99% of industrial waste to failure in the end of the reasons.
Low-temperature plasma exhaust gas treatment equipment and the current commonly used odor gas treatment methods compared to the plasma industry waste gas treatment technology has the following characteristics:
Low temperature plasma technology used in the treatment of malodorous gas, with good treatment effect, low operating costs, no secondary pollution, stable operation, easy operation and management, that is, open and other advantages.
① dielectric barrier discharge generated by high electron energy, low temperature plasma density, to the commonly used plasma technology lion corona discharge) 1500 times, and almost all the role of malodorous gas molecules;
② technical reaction speed, the gas through the reaction zone speed of 3-15 m / s, that is, to achieve a good treatment effect, the other technical gas through the reaction zone speed of 0.01 m / s are difficult to achieve the treatment effect;
③ gas through the part of all the use of ceramic, quartz, stainless steel and other anti-corrosion materials, electrode and exhaust gas clockwise contact, fundamentally solve the low-temperature plasma technology equipment corrosion; other technology is the gas and electrode clock contact, the electrode in 3 months Or 1 year will cause serious corrosion, even if the gas is not corrosive, the ozone generated by the electrode will cause corrosion;
④ host for the complete set of industrial waste gas treatment device, in front with a dedicated tower, can effectively remove the dust and moisture in the exhaust, simple operation;
⑤ high degree of automation, equipment start, stop very quickly, with the use of open, for some of the chemical production of continuity, can be opened in production, do not produce the gap to stop running a lot of energy conservation;
⑥ lower operating costs than the commonly used regenerative burner RTO to save operating costs 5-8 times the operating cost per cubic meter of gas is only 0.3 to 0.9 points, part of the high concentration of exhaust gas can be diluted by the air after the technology;
⑦ wide range of applications, this is not affected by the temperature and the composition of pollutants, the smell of odor odor has a good decomposition of the odor, odor odor removal rate of 80-98%, after treatment of gas odor concentration reached the national standard The
