Decomposition Of Low Concentration Gas-phase Toluene From Indoor Air Using Plasma-driven Photocatalyst Reactor

In resent years, much attention is focused on indoor air pollution and the quality of indoor air has a vital impact on human health. It is a very important problem of improving indoor air quality. Because of energy crisis and outdoor air pollution, the application of air cleaner becomes a important method of improving indoor air quality in some polluted places seriously.There are some disadvantages of existing purification methods (eg. High-efficiency filtration, Negative-ion purificatin, UV-oxidation purification, Nano-photocatalysis, Non-thermal plasma), such as low energy utiliztion, low purification life, low purification efficiency and low entire purification efficiency. These methods could not meet the needs of low-concentration air pollutants from indoor air, so these purification methods should be mended for improving the purification efficiency of pollutants, decreasing the number of poision secondary products and improving the energy utiliztion.The following are the main contents: Discusse the possibility of activated carbon fiber as the carrier of nano-photocatalyst, develope a high purification efficiency and low-cost photocatalyst; Design a high purification efficiency and low-cost non-thermal plasma that is fit to the need of purification of indoor air, optimize the discharge methods and parameters; design the non-thermal driven photocatalyst reactor, compare the purification efficiencies of non-thermal and photocatalyst in series and non-thermal plasma driven photocatalyst; By production analysis using GC-MS of nano-photocatalysis, non-thermal plasma and non-thermal driven photocatalysis, filtrate a new purification methods of high complete purification efficiency, discusse the purification mechanism. The main conclusions are the following:...
