Abstract

The invention provides an energy-saving type VOCs (Volatile Organic Compounds) treatment device based on multi-stage dielectric barrier discharge and relates to the field of low-temperature plasmas, aiming at solving the problems that a sleeve type reactor cannot be used for treating gas in a large area, a flat plate type reactor is actually difficult to use and the energy consumption and cost are increased through cooling of a polar plate. A neon lamp voltage regulator is used for converting electric supply and a high-voltage power supply is provided for a multi-stage dielectric barrier discharge plasma generation device; gas flowing out from a first VOCs buffering room flows into the multi-stage dielectric barrier discharge plasma generation device; gas flowing out from the multi-stage dielectric barrier discharge plasma generation device flows into a second VOCs buffering room; a byproduct treatment device is used for removing ozone in the gas flowing out from the second VOCs buffering room; a temperature difference power generation device is used for converting heat generated by the multi-stage dielectric barrier discharge plasma generation device into electric energy. The energy-saving type VOCs treatment device is used for treating VOCs.

Description

technical field [0001] The invention relates to the field of low temperature plasma. Background technique [0002] In my country, VOCs (Volatile Organic Compounds) refer to organic compounds with a saturated vapor pressure greater than 70Pa at normal temperature and a boiling point below 260°C at normal pressure, or all organic compounds with corresponding volatility at 20°C with a vapor pressure greater than or equal to 10Pa. organic compounds. Scientific research shows that when the concentration of VOCs in the indoor air is too high, it is easy to cause acute poisoning. In mild cases, symptoms such as headache, dizziness, cough, nausea, and vomiting will occur. May be life threatening. [0003] With the continuous deepening of my country's industrialization process, air quality problems are increasingly affecting people's daily life. As an essential requirement for human life, good air quality has received more and more attention in recent years. However, since solvent...
