Abstract

The invention relates to an electrostatic precipitator (20), wherein the electrostatic precipitator comprises a non-metallic electrostatic filter (21) and the particle charging unit. The particle charging unit comprises one or more corona needle chargers (22) arranged in a distance from each other, wherein each of the needle chargers (22) have a tip;a guide surface (23) for surrounding each of theone or more needle chargers; wherein low power is arranged to be used for forming a wide electric field between a tip of the corona needle charger and the surrounding guide surface for ionizing particles of a gas stream passing through the formed wide electric field. The invention also relates to a supply air device comprising the electrostatic precipitator.

Description

technical field [0001] The present invention relates to a particle charging unit for use with a non-metallic electrostatic filter structure. Further, the present invention relates to an electrostatic precipitator including a particle charging unit, and an air blowing device. Background technique [0002] Different kinds of electrostatic precipitators (ESPs) are used to separate particles from air streams. Air cleaning equipment including such electrostatic precipitators are generally sold to the public. For example, the air cleaning device may be arranged in the air duct, or it may be a portable device. These electrostatic precipitators typically include a high voltage particle charging unit and a particle collector unit. For example, a particle charging unit typically comprises at least one corotron wire charger or several corotron pin chargers for ionizing or charging the particles present in the airflow with an electrical charge. A high-voltage particle charging unit ...
