Abstract


Air distribution is affected ESP collection efficiency is one of the main factors , currently available research results and practical applications show that the use of oblique flow technology, ESP collection efficiency is higher than the uniform air distribution esp. In this thesis, the intake air distribution inside the smoke deflector plate installed oblique flow is formed by adjusting the deflector mounting angle , spacing, and the number to change the flow pattern , using FLUENT software simulation ESP flow distribution within the three-dimensional oblique . The simulation results show that : In the air distribution plate mounted spoiler different parameters can form helical flow ; in the importing second , three air distribution baffle plate installed the simulation results with experimental conditions basically consistent flow distribution , the deflector plate spacing and the angle of 504mm and 55 ° , respectively , can form a helical flow better ; import third layer only in the air distribution plate mounted spoiler , spoiler pitch and tilt angles of 400mm and 55 °, while at the end of the installation of a uniform electric field at the exit aperture ratio of 50% air distribution plate , exports than imports tobacco smoke chamber centerline tank centerline 2m high , it can form an ideal oblique air flow pattern . In addition, the formation of oblique airflow degree of optimization are also discussed. These are available for the use of oblique airflow design and operation of the ESP to provide reference and basis.
