Description
Technical Field
The invention belongs to the technical field of pollutant treatment, and particularly relates to a device for treating pollutants by using an oscillating centrifugal medium to block discharge.
Background
At present, the level of domestic industrialization is continuously improved, novel pollutants continuously appear, and environmental problems face more and more challenges. The emission standard required by national policy is improved year by year, and the traditional pollutant treatment method is very weak in the face of novel organic pollutants, so that the advanced oxidation technology is widely applied. Plasma technology, one of the advanced oxidation technologies, is being increasingly used in the field of pollutant treatment.
Advanced oxidation technology pollutant treatment refers to the utilization of the strong oxidizing property of high-energy active groups to carry out thorough oxidation of pollutants. The plasma is composed of positive ions, negative ions, electrons, radicals and active groups, and is called plasma because the electric quantities of positive charges and negative charges are equal. Plasma is a basic form in which a fourth substance other than solid, liquid, and gas exists. The electron temperature in the low-temperature plasma is very high, and the temperature of ions and gas is close to room temperature, so that thermodynamic non-equilibrium can be achieved, and the low-temperature plasma is also called as low-temperature plasma. The low-temperature plasma has higher electron energy and can promote the chemical reaction. The low-temperature plasma contains a large amount of active free radicals, has very high oxidizability, and can efficiently and non-selectively degrade organic macromolecules in pollutants.
Dielectric barrier discharge is an effective way to generate low temperature plasma, and particularly refers to a discharge form with insulating dielectric inserted into the discharge space. The dielectric barrier discharge can perform stable and uniform discharge at high voltage and normal pressure because the dielectric barrier discharge has the characteristics of corona discharge and glow discharge at the same time, and the electron density of the dielectric barrier discharge is high. Compared with other discharge forms, the dielectric barrier discharge form device has lower cost, higher energy utilization rate and higher energy utilization rate.
At present, a multi-type plasma reaction device is developed and applied to water treatment, but still has a plurality of defects which are difficult to overcome in the aspects of mass transfer, discharge efficiency improvement and the like. For example, in mass transfer, a micro-bubble method is used to increase the mass transfer efficiency, but the complexity of the device is too high, and the maintenance cost is too high.
