Description
Technical Field
The invention belongs to the technical field of pollutant treatment, and particularly relates to a rotary spiral bubbling dielectric barrier discharge pollutant treatment device.
Background
The environmental problem is one of the key problems which need to be solved urgently by human development, and the most urgent is how to treat the serious pollution of water resources. The treatment method for easily degradable sewage is mature and has good treatment effect, but the high-efficiency treatment method for high-concentration and difficultly degradable wastewater discharged by industries such as metallurgical electroplating, textile printing and dyeing, chemical pharmacy, petroleum/coal chemical industry and the like is urgently researched. At present, scholars at home and abroad mostly adopt an advanced oxidation technology to treat the high-concentration organic sewage, and the effectiveness of the technology is verified through theory and experiments, so that the technology becomes a research hotspot of the current global water treatment technology.
The material will exhibit different aggregation states at different temperature ranges or at different energy ranges. It is believed that plasma is a fourth type of material state of aggregation that is distinct from conventional solids, liquids, and gases. The natural plasma is widely present in the vast universe, and in fact 99% of the substances in the universe exist in a plasma state. The concept of the fourth physical state of plasma was proposed by the british physicist Crockes in 1879, but until 1928 the american chemist Langmuir first adopted "plasma" to mean the ionized gas produced by glow discharge, and "plasma" was translated into "plasma" at the earliest arrival in china and was later changed into "plasma".
Among advanced oxidation technologies, plasma water treatment technology is currently the focus of attention. It integrates the actions of high-energy electron radiation, ozone oxidation and ultraviolet light decomposition into one body, and can obtain good treatment effect. At present, dielectric barrier discharge, sliding arc discharge, corona discharge, glow discharge, radio frequency microwave discharge and the like are mainly adopted for generating plasma in water treatment.
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. How to consider the promotion of the discharge efficiency and the enhancement of the mass transfer, thereby promoting the whole treatment efficiency, increasing the economic benefit and becoming the development direction of the plasma reaction device.
