[Abstract]:In order to meet the need of pollutant treatment in the whole industrial plant, this paper developed a compound purification device which integrates many new technologies such as low temperature plasma, TiO_2, ultraviolet photocatalyst and so on. Compared with the traditional air purification technology, the combined purification technology has the advantages of low energy consumption, high treatment efficiency and recycling of air energy after treatment, which is suitable for the purification of pollutants in various industrial buildings. In this paper, two kinds of composite purification schemes are designed based on the new technologies of synergistic low temperature plasma and TiO_2, UV photocatalyst purification at home and abroad, and based on theoretical analysis and numerical simulation, two kinds of composite purification schemes are designed. Finally, a scheme was chosen. In order to optimize the structure design and purification efficiency of the device, the author used Gambit,Fluent,chemkin-4.5,airpak and other software to model the device, and carried out numerical simulation. The simulation contents include the analysis of airflow distribution and the analysis of the purification effect of particulate matter. The operating efficiency of low temperature plasma reactor and the factors affecting the chemical reaction efficiency of pollutants were analyzed and so on. Finally, on the basis of simulation, the device is optimized, and the corresponding prototype is made. At the same time, the performance of the device is tested in the whole industrial building at 1:1. It mainly includes operation stability, airflow organization, treatment effect and so on. In order to verify the operation effect of the device in the whole workshop in large space, the author also uses airpak to simulate and analyze its airflow, and the experimental study is made on the treatment effect of the prototype to different particle size. The results show that the operation condition of the equipment is normal, the expected purification effect can be achieved, and the indoor air quality of the whole industrial plant can be satisfied.
