An electrostatic precipitator in one embodiment includes an outer housing defining an internal space, and a primary collector disposed therein which comprises a pair of nested inner and outer radial collecting walls. A collection annulus is formed between the walls which receives a flowing process gas stream. Electrodes within the annulus electrically charge particles entrained in the gas stream which electrostatically adhere to the collecting walls. In one embodiment, the collecting walls rotate through a stationary cleaning station in the housing which includes mechanical devices such as scrapers to automatically and mechanically remove the collected particles from the walls. The devices may be vertical drag chains with scrapers coupled thereto in one embodiment. The precipitator may be a wet electrostatic precipitator which treats an incoming wetted gas stream. The precipitator is especially adapted to remove sticky type particulate from the collecting walls.
