Low-temperature plasma is the fourth state of matter following the solid state, liquid state, gas state, when the applied voltage reaches the ignition voltage of the gas, the gas molecules are punctured, resulting in a mixture including electrons, various ions, atoms and free radicals. Although the temperature of electrons is very high during the discharge process, the temperature of heavy particles is very low, and the whole system presents a low-temperature state, so it is called low-temperature plasma. Low-temperature plasma degradation of pollutants is the use of these high-energy electrons, free radicals and other active particles and pollutants in the exhaust gas, so that the pollutant molecules in a very short period of time to decompose, and a variety of subsequent reactions in order to achieve the purpose of pollutant degradation.
Low-temperature plasma air purification equipment can significantly manage the pollution are: VOC, malodorous gases, odor gases, fumes, dust, can also be used for disinfection and sterilization. Low temperature plasma technology is a new purification process, does not require any additives, does not produce waste water, waste residue, will not lead to secondary pollution.
