Air purifier and method of purifying air

Abstract

According to an example aspect of the present invention, there is provided an air purifier comprising: an ionization chamber arranged for charging impurity particles in the incoming air;electrostaticcollector plates located after the ionization chamber and arranged for trapping the charged impurity particles. The air purifier further comprises a washing system above the electrostatic collector plates, which washing system is arranged for dispensing a cleansing solution onto the electrostatic collector plates;a fan system capable of two-mode action: a purification mode of aspirating air to bepurified upwards,into the ionization chamber and subsequently through the electrostatic collector plates, and a drying mode of blowing air in the opposite direction.

Description

technical field [0001] The present invention relates to air cleaners, and more particularly to air cleaners with electrostatic precipitators. Background technique [0002] An electrostatic precipitator (ESP) or electrostatic air cleaner is a device that removes fine particles such as dust and smoke from a flowing gas by electrostatic attraction. The ESP ionizes, or charges, the particles as incoming air is drawn into the electronic battery. The charged particles are then grounded or attracted and captured by positive / negatively charged collector plates. Trapped particles stick to the plate until they are removed. Collector plates are usually formed as assemblies of parallel conductive plates or nested cylinders. [0003] Depending on the method of removing particles from the collection plate, electrostatic precipitators can be divided into two categories: dry and wet. The dry variant is the most used basic form of ESP. In an industrial-scale dry ESP, accumulated dust ca...
