Performance of High Velocity Electrostatic Precipitator for Road Tunnel
نویسندگان
چکیده
The particles emitted from diesel engine exhaust have low resistivity and extremely small in the range of 70-120nm. An electrostatic precipitator (ESP) has been extensively used for the collection of these particles. A two-stage ESP using charging section and collection section has been installed for the collection of diesel particles and improving the visibility index in road tunnels. The characteristics of ESP in road tunnels are demanded to process in high gas flow velocity, miniaturization and high collection efficiency. In this study, the underlying data of ESP performance was extracted in condition of high gas flow velocity. The gas flow velocity was in the range of 10 to 25 m/s. The collection efficiency for experiment and the simulation were compared.

متن کاملInstantaneous and time - averaged velocity fields in a wide electrostatic precipitator
the electrohydrodynamic (EHD) flow in a relatively wide electrostatic precipitator (ESP) (width:height = 2) is 2-or 3-dimensional (3D). The previous our measurements of 3D time-averaged flow velocity fields suggested that the flow in the ESP duct centre is almost 2-dimensional. In this paper we present both the 3D instantaneous and time-averaged flow velocity fields in a relatively wide ESP (wi...
