▎ 摘 要
NOVELTY - Formaldehyde removal device comprises a air purification filter and a plasma generating device arranged coaxially, and the plasma generating device. The air purification filter screen is respectively close to the air inlet and the air outlet. The surface of the air purification filter screen is evenly provided with a nano-zinc oxide graphene coating. The thickness of the nano zinc oxide graphene coating is 0.3-1.5 mm. The nano-zinc oxide graphene coating comprises nano-zinc oxide and graphene, and the mass ratio of the two is 50-300:1-3. USE - Used as formaldehyde removal device. ADVANTAGE - The device: has simple structure, strong practicability, safety, no pollution, and high efficiency. DETAILED DESCRIPTION - AN INDEPENDENT CLAIM is also included for preparing a formaldehyde removal device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the formaldehyde removal device.
