Principle of external injection plasma technology and its application in waste gas treatment

In the process of modern agricultural production, industrial manufacturing, electronic coating, sewage treatment, garbage treatment and composting, a large amount of odor and organic waste gas with peculiar smell will be produced. The unorganized waste gas will pollute the surrounding environment, and also cause serious harm to human health and ecological environment, More and more people pay attention to how to effectively control these odor and organic waste gas. Sewage treatment plant, rubber production, breeding plant, garbage station, landfill, etc. are the main sources of odor. Domestic waste, industrial waste, sewage and so on produce harmful gases under the action of microorganisms. These odors often include volatile organic compounds (v0c), inorganic compounds, non methane hydrocarbons, hydrogen sulfide, ammonia, mercaptans, phenols and so on.

Principle of zj-dl-k injection plasma technology

Zhongjing zj-dl-k external injection plasma is through the natural suction and power delivery mode. It can not only avoid the damage caused by the pollution of dust and humid gas in the exhaust gas, but also avoid the technical disadvantages of conventional low-temperature plasma which is flammable and explosive.

The external plasma waste gas treatment equipment of Zhongjing generates active ions from clean air, and mixes the generated ions, active oxygen and free radicals into the waste gas treatment system through natural inspiration and power transmission mode. The zj-dl-k injection plasma system of Zhongjing adopts integrated modularization, which is composed of filter unit, flow equalizing hood, dehumidification and drying device, buffer bin, ion generation module, air-conditioning system and so on The number of modules is selected according to the need of waste gas treatment,

Zj-dl-k injection plasma treatment of industrial waste gas is a new technology used at home and abroad in recent years. The principle of injection plasma purification equipment is to use special high voltage power supply to ionize the gas at room temperature and atmospheric pressure to obtain non-equilibrium plasma, that is, to produce a large number of high-energy electrons and active particles such as h, O, oh, The pollutant molecules in the air are excited by high-energy electron collision, and the atomic bond breaks to form small fragment groups. Active particles such as h, O, oh react with the broken molecular groups and free radicals of pollutants, and finally convert the pollutants into harmless substances, such as organic matter degradation to CO2, H2O, etc; NH3 is degraded to N2 and H2O.

Advantages of Zhongjing injection type plasma waste gas treatment equipment

1. Safe and reliable: the exhaust gas does not contact the plasma generator, the air in the environment is used as the core device of ion unit reaction, and the flammable and explosive gas will not be ignited and exploded due to electric spark and high-voltage static electricity.

2. Stable operation: the exhaust gas does not contact the generation process of high pressure plasma module, and the high humidity pollution gas does not affect the stability of plasma electrode, and the operation process of ion module is more stable and controllable.

3. High efficiency: compact structure, small footprint, increased electrode, high ion beam density, which is conducive to the ion strength in the module, so as to increase the activity of generated ions and improve the efficiency without increasing energy consumption.

4. Simple maintenance: no external water source and gas source, no additional consumables besides power consumption, low operation and maintenance cost. The equipment is installed outside the waste gas pipeline, and can be maintained daily without shutdown.

5. Adjustable power: the power of the equipment can be adjusted on line according to the actual situation.

6. Intelligent control: CPU integrated control, online real-time monitoring of flow, temperature, pressure and other key process parameters.
