working principles:
High voltage pulsed power supply developed by Foshan Noah Electrical Co., Ltd. provides power source for plasma generators and provide high voltage ionization power source for gas purification towers. The power supply conforms to the Townsend discharge curve and supports multi-electrode discharge. During the working process, two electric potential fields are established at the same time, that is, the ionization electric field(the voltage is about 0.8~1.6 times the rated voltage)and adsorption electric field (the voltage is about 0.6~0.8 times the rated voltage), and then generate plasma in the reaction chamber. In the plasma state, there are a large number of active particles such as high-energy electrons, free radicals, dissociated atoms, and excited molecules. They have strong reactivity, and chemical reactions that are difficult to achieve by other means can be carried out in the plasma environment. There are two reaction steps: One is the steep front and extremely narrow pulse width high-voltage pulsed corona discharge. It can obtain non-equilibrium plasma at normal temperature and pressure, and can excite the discharge electrode (cathode) to release a large number of high-energy electrons instantly. High-energy electrons get energy from the electric field, move at a very high speed, and collide with molecules during the movement. It can directly interact with malodorous gas, decompose the gas into other substances and remove. At the same time, high-energy electrons generate excited particles, free radicals, ions and additional electrons through electron impact, excitation, and ionization of gas-carrying molecules. Due to the strong reactivity of the generated active particles, they can interact with malodorous gases, oxidize, reduce or decompose pollutant molecules, and transform malodorous gases into other environmentally harmless substances. On the other hand, the active particles produced by the activation will have high kinetic energy and internal energy under the action of the electric field, which can break the chemical bonds of the malodorous gas, promote its decomposition into simple atoms or harmless molecules, and finally realize the purification of the malodorous gas. (E.G.:H2S→H++S2-;NH3→N2+H2)
