Low temperature plasma industrial waste gas treatment equipment

Brief introduction of plasma reactor: First, the principle of dual-plasma plasma reactor The low-temperature plasma is the fourth state of the material after the solid, liquid, and gaseous state. When the applied voltage reaches the ignition voltage of the gas, the gas is broken down, resulting in the Mixtures of electrons, various ions, atoms, and radicals. Although the electron temperature is high during discharge, the temperature of heavy particles is very low and the entire system exhibits a low temperature state, so it is called a 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 decompose in a very short time, and follow-up reactions to achieve decomposition of pollutants the goal of.

Dual-media low-temperature plasma industrial exhaust gas treatment complete sets of equipment and technology as a new type of gaseous pollutants treatment technology is a cross-integrated electronic chemistry technology integrating physics, chemistry, biology and environmental science, as it can be easily It is one of the most promising and most effective technical methods for the treatment of atmospheric pollution at home and abroad, with its highly efficient decomposition of pollutant molecules and low processing energy consumption. It has broad prospects for application and promotion, and it is an organic waste gas for industrial VOCs. The management of odorous gases has opened up a new way of thinking.

The low-temperature plasma generates highly-chemically active particles such as electrons, ions, radicals, and excited molecules. Contaminants in the exhaust gas react with these active groups with higher energy, and eventually they are converted into substances such as CO2 and H2O to achieve the purpose of purifying the exhaust gas.

Second, the performance characteristics (1) can be adapted to high concentrations, atmospheric quantities, different gaseous substances purification treatment, can be in the high temperature 250 °C, low temperature -50 °C environment can be run in the purification zone, especially in the humid, even the humidity of the air saturation The environment can still operate normally and work continuously 24 hours a day. The long-term operation is stable and reliable. (2) Low power consumption, no mechanical action, high degree of automation, simple process, simple and convenient operation. (3) Wide application scope, high purification efficiency, especially applicable to multi-component malodorous gases that are difficult to handle by other methods, and can effectively remove major pollutants such as volatile organic compounds (VOC), inorganic substances, hydrogen sulfide, ammonia, and mercaptans. As well as various bad odors, it has the ability to kill bacteria, viruses, and other microorganisms in the air, and it also has a significant anti-mildew effect. (4) "Low-temperature plasma" equipment is light in weight and small in size. It can be placed and laid horizontally according to the requirements of the site. The exhaust gas can be purified completely according to the concentration, flow rate and composition of the exhaust gas.

(5) The response is quick and stops very quickly. (6) Low-temperature plasma exhaust gas treatment is a dry purification process. It is a brand-new purification process. No additives are added during the operation process, no waste water and waste residue are generated, and secondary pollution is not caused.

Third, the scope of application can be used for food additives, leather processing, photosensitive materials, petrochemicals, pharmaceutical industry, animal husbandry products farms, chemical fiber plants, pulp mills, sewage pumping stations, various types of sewage treatment plants, paint, feed and fertilizer processing plants , Organic waste, odor, odor, and other pollution problems exist in many industries such as automobile manufacturing, public toilets, and excreta transfer stations. It can be applied to the treatment of industrial waste gas as well as indoor air purification. It is a new type of air environment clean technology and product with extremely wide range of uses.
