Description

A kind of aeration-type ultraviolet catalytic air purifier
Technical field
The utility model relates to air purification field, particularly a kind of aeration-type ultraviolet catalytic air purifier.
Background technology
Acceleration along with industrial expansion and urbanization, the problem of modern city Air Contamination is more and more serious, easily suffer from all serious diseases behind the air of people's suck pollution, various air pollutants enter human body by number of ways, impact on human body is again many-sided, and its harm also is very serious.In the city, the degree of room air pollution exceeds doubly a lot than the open air, the more important thing is the urban population more than 80%, time more than seventy percent is spent indoor, and children, pregnant woman and chronic patient, because longer than other crowds in the time of indoor stop, the harm that is subject to indoor environmental pollution is just more remarkable, children particularly, they more easily are subject to the harm of room air pollution than the adult.On the one hand, children's health is just in growth and development, and it is high nearly 50% that respiratory capacity is pressed the weight ratio adult, and on the other hand, children have time of 80% to live in indoor.The World Health Organization announces: the whole world has 100,000 people to die from asthma because of room air pollution every year, and 35% is children wherein, and Chinese children asthma illness rate is 2%-5%, and wherein 85% ill child age is below 5 years old.
Formaldehyde is defined as a class carcinogenic substance by the World Health Organization, and thinks and exist causality between formaldehyde and the Leukomogenesis.Formaldehyde is that the major pollutants in the family are newly fitted up by China at present, and children are people at highest risk of indoor environmental pollution, and the relation between formaldehyde pollution and the leukemia of children should cause that the whole society pays close attention to.
The method that the harmful substance of air is approved by World Developed Countries always in photoactivation (photocatalyst) the technology decomposition catalyst chamber, but photocatalysis technology is applied to technical bottleneck of indoor ubiquity---the problem of illuminating area and oxygen concentration, that is to say, indoor the very strong UV-irradiation of large tracts of land (because human body can not contact ultraviolet light) can not be arranged, and airborne oxygen concentration ratio does not reach desirable effect about 20%.Because photocatalysis is to belong to low temperature deep reaction technology, the nano particle of its catalyst (photocatalyst) irriate under the ultraviolet light irradiation of certain wavelength generates the electron hole, the water generates hydroxyl free radical of hole decomposition catalyst adsorption, electronics makes the hydrogen reduction around it become active ion-oxygen, thereby possess extremely strong redox, the various pollutants of photocatalyst surface are destroyed and bacterial virus kills.Therefore, increase catalyst oxygen concentration and illuminance on every side and will strengthen its catalytic decomposition effect.
Many equipment that utilize photocatalysis to remove formaldehyde, purify air are arranged on the market, but all have area deficiency and the two inadequate large defectives of catalyst ambient oxygen concentration of photocatalytic agent, cause it to produce little effect, even allow the city dweller that photocatalytic product is thrown doubt upon.
The utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of aeration-type ultraviolet catalytic air purifier, and its photocatalytic agent area is large, and the oxygen concentration around the catalyst is high, has significant oxidation, purification effect.
The technical scheme that the invention for solving the technical problem adopts is:
A kind of aeration-type ultraviolet catalytic air purifier, comprise the casing that is provided with air intake vent and air outlet, be provided with the air channel that connects into air port and air outlet in the described casing, be provided with blower fan on the air channel, be provided with the catalysis chamber on the described air channel, described catalytic chamber chamber interior walls scribbles photochemical catalyst, the indoor ultraviolet lamp tube that is provided with of catalytic chamber; Also be provided with oxygenerator in the casing, the oxygen output tube of oxygenerator connects the catalysis chamber.
As to further improvement in the technical proposal, be provided with the control display module for control ultraviolet lamp tube and oxygenerator work in the described casing.
As to further improvement in the technical proposal, described air intake vent place is provided with screen pack.Further, described screen pack is multistorey strainer mesh, comprises one or more combinations in plain gauze, active carbon filter screen and the cold catalyst filter screen.
As to further improvement in the technical proposal, be provided with on the described oxygenerator and stretch out the outer external oxygen hose of casing, outside machine, export high-concentration oxygen by external oxygen hose, for oxygen uptake or other purposes behind the user movement.
The beneficial effects of the utility model are:
Be compared with the prior art, it is indoor that aeration-type ultraviolet catalytic air purifier of the present utility model is directly delivered to catalytic chamber to the high-concentration oxygen of making, improve photochemical catalyst oxygen concentration on every side, the efficient of catalysis is improved greatly, the active oxygen ion that produces can carry out strong oxidation to airborne harmful substance, harmful substance in purifying air, and simultaneously for room air increases oxygen, improve oxygen concentration.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and example.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
