Low temperature plasma skill is a powerful air sterilization, purification and deodorization skill. Low temperature plasma skill is a cross comprehensive skill integrating physics, chemistry, biology and environmental science. The obvious feature of this skill is that it has both physical, chemical and biological effects on pollutants, and has obvious advantages such as low energy consumption, high efficiency and no secondary pollution.
The principle of low-temperature plasma technology to deal with pollutants: under the effect of an external electric field, a large number of energy carrying electrons triggered by dielectric discharge bombard pollutant molecules to ionize, dissociate and excite them, and then cause a series of chaotic physical and chemical reactions to transform the chaotic macromolecular pollutants into simple small molecular safety substances, Or the toxic and harmful substances can be transformed into non-toxic and harmless or low toxic and low harmful substances, so that the pollutants can be degraded and removed. Because the average energy of the electrons that occur after ionization is 10 ev, properly controlling the reaction conditions can complete the chemical reaction that is difficult or slow under normal circumstances and become very fast. As a high and new technology with strong potential advantages in the field of environmental pollution treatment, plasma has been highly valued by relevant disciplines at home and abroad.
Low temperature plasma degradation of pollutants is to use the effect of these high-energy electrons, free radicals and other active particles and pollutants in the exhaust gas to make pollutant molecules decompose in a very short time, and make subsequent reactions to achieve the purpose of pollutant degradation. (Note: Compared with high-temperature plasma, low-temperature plasma belongs to normal temperature operation.
The plasma reaction zone is rich in extremely high substances, such as high-energy electrons, ions, free radicals and excited molecules. The pollutants in the exhaust gas can react with these substances with high energy, so that the pollutants can break down in a very short time, and the subsequent reactions can occur to explain the pollutants. Compared with the traditional low-temperature plasma technology, the discharge density of the plasma technology is 1500 times that of the corona discharge, which is why the traditional low-temperature plasma technology failed to control 99% of industrial waste gas.
Low temperature plasma Waste gas treatment equipment It can be widely used for the treatment of various pollutants, such as waste gas from plastic plants, sewage pump stations, cooking fume, odor from sewage treatment plants, tobacco industry waste gas and other pollutants. Its market prospect is very promising.
The purification effect of low-temperature plasma also has obvious biological effect. The electrostatic effect that breaks out on the surface of various bacteria, viruses and other microorganisms is greater than the surface tension of the cell membrane, which destroys the cell membrane and leads to the death of microorganisms. Therefore, low-temperature plasma deodorization technology has excellent disinfection and sterilization effect.
