Abstract

Electrostatic precipitator (ESP) units have wide application in lots industries processes as gas filtration devices. Regarding their high efficiency, further improvement is still required. Wide ESP (plate-to-plate distance greater than 400 mm) is one of a promising way to improve existing ESP due to its ability to reduce equipment investment significantly. However, its large-scale application has been limited because it may potentially lead to collection efficiency reduction. This article focuses on the study of two major effects when several different electrode configurations are applied. The electrohydrodynamic (EHD) flow pattern inside ESP and particle collection efficiency were investigated by using particle image velocimetry (PIV) and electrical low pressure impactor (ELPI) respectively. Results suggested that the collection efficiency of wide ESP is rather complicated and highly related to inner gas flow pattern.
