▎ 摘　　要

NOVELTY - The air purifying device (1) comprises a grounded honeycomb structure (2) having hexagonal openings (5) and supported by frame. The ionization needles (4) are arranged downstream of honeycomb, where the needles are coaxially aligned with respective center axis of an opening of the honeycomb, and collector plates. The needles are attached to support structures in the form of printed circuit board (PCB) rails, and are partially over-molded by plastic structures. The material of the needles is wolfram, graphite, graphene, a noble metallic material or an inert material. The tips (7) of the needles (4) are arranged 5 mm to 25 mm downstream of the honeycomb structure. USE - Air purifying device e.g. electrostatic precipitator used in arrangement (claimed) for separating materials from gas flow. ADVANTAGE - The device is scalable for different sizes, modular for maintenance and cleaning, and allows robotic assembly lines. The positive ionization voltage decreases the ozone (O 3 ) generation of the ionization process and enables the possibility to leave the active carbon filter out of the electrostatic precipitator (ESP) module. The ionization panel provides easy maintenance, is washable, and provides a low air drag method of air purification. The technology is able of running with very little energy consumption and provides also the ability to save energy in air ventilation, where a fan is typically used for overcoming fiber filter air drag. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for separating materials from an air flow. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the air purifying device.
