The principle of injection plasma technology and its application in waste gas treatment
In the processes of modern agricultural production, industrial manufacturing, electronic coating, sewage treatment, garbage treatment, and composting, a large number of odors and organic waste gases with peculiar odor are generated. The unorganized exhaust gases cause pollution to the surrounding environment, and also cause serious harm to human health and the ecological environment. More and more people are paying attention to how to effectively control these odors and organic waste gases. Sewage treatment plants, rubber production, aquaculture plants, garbage stations, garbage landfills, and other major sources of odor. Domestic waste, industrial waste, sewage, etc., produce harmful gases under the action of microorganisms. These odors often include volatile organic compounds (V0C), inorganic substances, non methane total hydrocarbons, hydrogen sulfide, ammonia, mercaptans, phenols, etc.
ZJ-DL-K Injection Plasma Equipment
Zhongjing ZJ-DL-K type injection plasma has multiple independent design patents (Patent No.: ZL 2018 2 0669759.2/ZL 2021 2 0371592.3). When the equipment is used, it enters the mixing reaction tank through natural suction and power transmission modes, which not only can avoid damage caused by dust and humid gases in the exhaust gas, but also prevent the plasma electrode from contacting the exhaust gas during the entire exhaust gas treatment process, It can effectively avoid the technical drawbacks of conventional low-temperature plasma that are flammable and explosive.
The Zhongjing external plasma waste gas treatment equipment generates active ions from clean air, and mixes the ions, active oxygen, and free radicals generated into the waste gas treatment system through natural inspiration and power transmission modes. The Zhongjing ZJ-DL-K injection type plasma system adopts an integrated modular design, which is composed of a filter unit, a flow equalizing hood, a dehumidification and drying device, a buffer bin, an ion generation module, and an inverter high-voltage device, Select the number of modules for combination based on the amount of air required for waste gas treatment,
ZJ-DL-K type injection plasma treatment of industrial waste gas is a new technology adopted at home and abroad in recent years. The principle of injection plasma purification equipment is to use a special high-voltage power supply to ionize the gas under normal temperature and pressure to obtain a nonequilibrium plasma, which generates a large number of high-energy electrons and active particles such as H, O, and OH, and the pollutant molecules in the air are excited due to high-energy electron collisions, And atomic bond breakage to form small fragment groups, where active particles such as H, O, and OH undergo a series of reactions with the broken molecular groups and free radicals of the pollutants, ultimately transforming the pollutants into harmless substances, such as the degradation of organic substances into CO2 H2O, etc; NH3 is degraded into N2 and H2O.
Advantages of Zhongjing Injection Plasma Waste Gas Treatment Equipment
1. Safety and reliability: The exhaust gas does not contact the plasma generator, and the air in the environment is used as the core device for the ion unit reaction. It will not ignite and explode flammable and explosive gases due to electric sparks and high-voltage static electricity.
2. Stable operation: The exhaust gas does not contact the high-voltage ionization module generation process, and does not affect the stability of the plasma electrode due to humidity and contaminated gases. The operation process of the ion module is more stable and controllable.
High efficiency: compact structure, small footprint, high ion beam density due to increased electrode size, which is beneficial to the ion strength within the module, thereby increasing the activity of ion generation and improving efficiency without increasing energy consumption.
4. Simple maintenance: no need to connect external water and gas sources,? There is no need to add consumables in addition to electric energy consumption, and the operation and maintenance costs are low. The equipment is installed outside the exhaust gas pipeline, and daily maintenance can be performed on the equipment without stopping production.
5. Adjustable power: The power of the equipment can be adjusted online according to the actual situation, and the power of the equipment can be adjusted arbitrarily.
6. Intelligent control: CPU integrated control monitors key process parameters such as flow, temperature, and pressure in real-time online.
Application fields: sewage treatment plants, electronic manufacturing, rubber plants, petrochemical industry, pharmaceuticals, sewage treatment, coatings, leather processing, photosensitive materials, automobile manufacturing, food processing plants, printing and dyeing plants, garbage treatment plants, public toilets, slaughterhouses, livestock farms, fish processing plants, feed processing plants...
