Abstract
An air cleaning device includes a shell, the positive surface of the shell is provided with an air inlet, pre-filter layer and high-efficiency filter layer, the upper part or the back of the shell is provided with a clean air outlet, and a honeycomb-shaped photochemical catalytic oxidation device mainly based on titanium dioxide is positioned between the air inlet and the clean air outlet. A high-intensity UV lamp is disposed on the photocatalytic oxidation device. The utility model uses a high efficiency filter layer combined with photochemical catalytic oxidation device, the high efficiency filter layer removes suspended particles in the air, including pollen, mould and other small particles, and the photocatalytic oxidation device transforms volatile organic compounds in the air into carbon dioxide and water and causes RNA and DNA of all bacteria to be damaged, to clean up the air thoroughly. The air cleaner of the utility model in particular cleans VOC pollution to indoor air and eliminate completely the vast majority of VOC polluted indoors.
Description
Technical field
The utility model is a kind of air cleaning unit, particularly is specifically designed to the purifier of volatile organic matter in purifying the air of a room.
Background technology
The ZL00249112 patent disclosure a kind of air cleaning unit, its structure is, housing bottom surface or side have the air intake place, and housing top or side have clean air outlet and electronic control part, have the charcoal absorption filter course between air intake place and clean air outlet.The adsorbent layer thickness of granular active carbon must be greater than 5 centimetres; The charcoal absorption filter course is wrapped with the high efficiency filter layer.This device since will be often to processings of regenerating of charcoal absorption filter course, influence is use normally; And the active carbon after the regeneration processing also will be changed the increase cost; The adsorption efficiency of activated carbon air purifying device is also very limited.
Summary of the invention
The purpose of this utility model is, overcome the shortcoming of above-mentioned air cleaner equipment structure, a kind of air purifier of novel concept is provided, a kind of air cleaner and the decontamination system that adopt high efficiency particulate air filter and photocatalytic oxidation device to combine, middle low concentration volatile organic matter specially purifies the air of a room.
The utility model structure includes housing 7, and the housing front has air intake 1, preposition filter course 2, and the housing top or the back side have clean air outlet 6, has photochemical catalysis oxidation unit 4 between air intake 1 and clean air outlet 6.
Photochemical catalysis oxidation unit 4 can be cellular net, mesh to be shaped as hexagon circular or square, the surface of net scribbles the catalyst coat based on titanium dioxide.
In photochemical catalysis oxidation unit 4 fronts high intensity ultraviolet lamp 5 can be housed.
The method that the utility model adopts high efficiency filter layer and photocatalytic oxidation device to combine, the high efficiency filter layer can be removed airborne suspended particulate, as pollen, mould and other fine particle, photocatalytic oxidation device then can be converted into carbon dioxide and water with airborne volatile organic matter.
The utility model adopts the mode of flow filtration and photochemical catalytic oxidation to purify the air of a room.By efficient pump drainage wind room air is sucked clarifier, cleaned air passes is discharged by clean air outlet.The core of clarifier is the photochemical catalysis oxidation unit.This photochemical catalysis oxidation unit adopts a kind of cellular material, and catalyst is coated in the cellular material surface, catalyst is the metal oxide based on titanium dioxide, adopt high-intensity ultraviolet light irradiation titanium dioxide catalytic surface layer, thereby activate its surface, make by the oxidized back of its volatile organic matter and generate carbon dioxide and water, and RNA of various bacteriums and DNA are destroyed, reach the purpose that thoroughly purifies air.Air purifier can arbitrarily move indoor, can suck air from all directions, from the positive air inlet of clarifier, from the top or back side exhaust.The utility model is specifically designed to the pollution of the VOC of cleaning room air, most VOC of indoor pollution thoroughly can be removed.The utility model can have domestic type and industrial two kinds.
