Abstract

The utility model discloses an air purifier's photocatalyst subassembly, be a square photocatalyst section of thick bamboo, set up the ultraviolet lamp at photocatalyst section of thick bamboo center including upper cover plate, cross -section, outside link and time holding ring, lower holding ring will photocatalyst section of thick bamboo lower surface location support and through the outside link with upper cover plate fixed connection. The utility model discloses a honeycombed structure, specific surface is big, and the filter effect is more excellent, self no windage in addition, the air current can freely shuttle back and forth inside and outside a photocatalyst section of thick bamboo, uses coordinately titanium dioxide with the active carbon, and titanium dioxide can produce very strong catalytic activity under the ultraviolet ray, and the active carbon enriches hazardous gas such as aldehydes among the micropore adsorption of air, benzene class, nitrogen oxide and various peculiar smell, stink through the surface. Can still have the long lasting function of disinfecting of broad -spectrum simultaneously with active carbon adsorption's pollutant oxidation and decomposition through light struck photocatalyst matter.

Description

The photocatalyst component of air purifier

Technical field

The utility model relates to technical field of air purification, particularly relates to a kind of photocatalyst component of air purifier.

Background technology

Air purifier is also known as " air cleaner ", air cleaner, clarifier, refer to and can adsorb, decompose or transform various air pollutants (generally comprising the finishing pollution of PM2.5, dust, pollen, peculiar smell, formaldehyde and so on, bacterium, anaphylactogen etc.), the product of effective raising air cleanliness, is mainly divided into family expenses, commercialization, industry, building.

There are multiple different technology and medium in air purifier, enable it provide air that is clean and safety to user.Conventional air purifying process has: adsorption technology, negative (just) ion technology, catalysis technique, photocatalyst technology, superstructure light mineralising technology, HEPA high efficiency filter technology, electrostatic precipitation technology etc.; Material technology mainly contains: photocatalyst, active carbon, pole charcoal heart filter core technology, synthetic fibers, the efficient material of HEAP, negative negative oxygen ion generator etc.Existing air purifier is adopted as compound more, namely have employed multiple purification techniques and material medium simultaneously.

In prior art, although some have employed photocatalyst treatment technology, be generally all by a simple plate-shaped design at that time, adopt the mode of the anterior air-out of back air intake, this just causes there is larger pressure reduction before and after tabular, and gas RT is short, and it should be effective not utilize performance.

Utility model content

The purpose of this utility model is the technological deficiency for existing in prior art, and provides a kind of photocatalyst component of air purifier.

The technical scheme adopted for realizing the purpose of this utility model is:

A kind of photocatalyst component of air purifier, comprise upper cover plate, cross section is square photocatalyst cylinder, be arranged on the uviol lamp at photocatalyst cylinder center, outside link and lower locating ring, described lower locating ring is by described photocatalyst cylinder lower surface positioning supports and be fixedly connected with described upper cover plate by outside link.

Described photocatalyst cylinder four sides are respectively aluminium base honeycomb nano titanium oxide screen pack or aluminium base Honeycomb-type activated carbon screen pack.

The side facing each other of described photocatalyst cylinder is respectively aluminium base honeycomb nano titanium oxide screen pack and aluminium base Honeycomb-type activated carbon screen pack.

Two adjacent screen packs are fixedly connected with screw by upper and lower two L shape connecting plates.

Compared with prior art, the beneficial effects of the utility model are:

The utility model adopts honeycomb-shaped structure, specific area is large, filter effect is more excellent, and self is without windage, air-flow can inside and outside photocatalyst cylinder free shuttling, be combined with active carbon by titanium dioxide, titanium dioxide can produce very strong catalytic activity under ultraviolet light, and active carbon enriches toxic and harmful and various peculiar smell, the stink such as aldehydes, benzene class, nitrogen oxide in micro-porous adsorption air by surface.Penetrate photocatalyst matter through illumination and by the pollutant oxidation Decomposition of charcoal absorption, harmless CO can be converted into ₂and H ₂o, also has the sterilizing function of broad-spectrum long-acting simultaneously, more can show the filter sterilization effect of nano titanium oxide and active carbon.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

As Figure 1-3, photocatalyst component of the present utility model comprises upper cover plate 310, be fixedly installed on the sterilizing ultraviolet lamp 320 of described upper cover plate lower central, and the light catalyst element 330 be fixedly installed on outside described ultraviolet lamp, outside light catalyst element 330, be also arranged with tubular active carbon filter 340 and tubular high efficiency particulate air filter 350 to form multiple-effect filter core simultaneously.Adopt the cooperation of uviol lamp and light catalyst element, photocatalyst filtering net is deposited on by catalysis material on filter material matrix, and photocatalyst matter is under the exciting of light, and produce electronics-hole pair, these electronics-holes are to the OH caught in air ^-and O ^2-, form the extremely strong free hydroxy (hydroxyl) of oxidisability and superoxide anion radical O ^2-, O ^-, rapid oxidation pollutant and peculiar smell, resolve into CO ₂and H ₂o, because oxidability is strong, can destroy the cell membrane of bacterium, thus kill bacteria.

Specifically, it is square photocatalyst cylinder 331 and outside link 332 and lower locating ring 333 that described light catalyst element 330 comprises cross section, described lower locating ring is by described photocatalyst cylinder lower surface positioning supports and be fixedly connected with described upper cover plate by outside link, namely upper cover plate and lower location-plate by outside link by photocatalyst cylinder clamping position.Four sides of described photocatalyst cylinder are respectively aluminium base honeycomb nano titanium oxide screen pack or aluminium base Honeycomb-type activated carbon screen pack, preferably include the aluminium base honeycomb nano titanium oxide screen pack of two pieces of opposite faces settings and the aluminium base Honeycomb-type activated carbon screen pack of two pieces of opposite face settings, adjacent screen pack is fixedly connected with screw by L shape connecting plate.

The utility model adopts tubular, honeycomb-shaped structure, specific area is large, filter effect is more excellent, and self is without windage, air-flow can inside and outside photocatalyst cylinder free shuttling, be combined with active carbon by titanium dioxide, titanium dioxide can produce very strong catalytic activity under ultraviolet light, and active carbon enriches toxic and harmful and various peculiar smell, the stink such as aldehydes, benzene class, nitrogen oxide in micro-porous adsorption air by surface.Penetrate photocatalyst matter through illumination and by the pollutant oxidation Decomposition of charcoal absorption, harmless CO can be converted into ₂and H ₂o, also has the sterilizing function of broad-spectrum long-acting simultaneously, more can show the filter sterilization effect of nano titanium oxide and active carbon.
