Description

Decorative Indoor Air Purifier

1. Technical field

The utility model relates to an indoor air purification device, in particular to a device for removing toxic and harmful gases such as aldehydes, benzenes, nitrogen oxides, germs and dust in the air by using activated carbon fiber, photocatalyst and ultraviolet technology. .

2. Background technology

Most people spend 80% of their lives indoors, and indoor air quality is closely related to human health. In recent years, with the continuous entry of a large number of daily chemicals, household appliances, new construction and decoration materials into residential and public buildings, the sources and types of pollutants in the indoor environment have increased dramatically. It is increasingly endangering human health and survival. Therefore, more and more attention has been paid to the air purification of human living and working environment.

The types of existing indoor air purification devices roughly include: physical methods such as filtration, adsorption, exhaust fan forced ventilation, and chemical methods such as chemical reagents and photocatalysts. Although they have a certain effect on removing harmful substances in the air, they all have disadvantages. They are all one-time treatment methods, and the release of indoor air pollutants is a long-term and lasting process; due to severe dust diffusion or lack of light, they cannot be used for air purification in furniture; most of the adsorbent materials such as activated carbon are black solid powder, which affects indoor air quality. Beautiful; Most chemical methods spray chemical reagents or photocatalysts on the surface of the release source, the spraying process is complicated, and the need for auxiliary facilities is large.

Chinese patent literature discloses a kind of indoor air cleaning device (CN2662909), is to be equipped with air inlet, activated carbon filter screen, far ultraviolet lamp, photocatalyst air cleaning net, negative ion generator exhaust fan, air outlet etc. sequentially in housing. It can purify harmful and toxic gases in bad air, and has powerful purification functions such as dust removal, disinfection, and sterilization. Its shortcoming is that, because the activated carbon and the photocatalyst are separated, there is a certain space distance between them, which is not conducive to the photocatalytic oxidation reaction of toxic and harmful gases on the activated carbon adsorbent, thus affecting the activation of activated carbon; secondly, the activated carbon filter screen The adsorption efficiency is about 100 times lower than that of activated carbon fiber, which affects the purification efficiency; thirdly, it uses a single-band ultraviolet lamp, which can degrade a small amount of organic matter. In addition, the above-mentioned prior art cannot be used to solve the problem of air pollution caused by room decoration, such as the purification problem of interior wall paint and toxic gas released from the closed space of furniture, and the cost is high.

3. Contents of utility model

The purpose of the new model is to provide a decorative indoor air purification device that is more conducive to photocatalytic oxidation reaction, continuous purification and better effect in view of the shortcomings and deficiencies of the prior art.

The technical solution to realize the purpose of this new model is: a decorative indoor air purification device, including an outer cover, an ultraviolet lamp placed in the outer cover and a photocatalyst air purification net, and the outer cover also has concentric circles, two or more Tubular photocatalyst/activated carbon fiber composite layers with different radii; the photocatalyst air purification net is tubular and similarly arranged on the periphery of the above two composite layers according to concentric circles.

There are two ultraviolet lamps, one for emitting A-band ultraviolet light, and one for emitting C-band ultraviolet light.

The outer cover is a tubular casing with upper and lower closures, and about 1/2 of the sides are evenly distributed with air holes; the top and bottom of the photocatalyst/activated carbon fiber composite layer and the photocatalyst air purification net are directly fixed on the outer cover. top and bottom plates.

The outer cover is a tubular casing with an open bottom; the two ultraviolet lamps are fixed on the top plate of the outer cover and arranged along the axial direction parallel to the outer cover.

In the above-mentioned basic technical solutions (first and second solutions), the tubular photocatalyst/activated carbon fiber composite layer is made by coating the photocatalyst on the activated carbon fiber tube. The composite structure makes the photocatalyst in the form of particles evenly spread on the entire active surface of the activated carbon, that is, the inner surface of all the pores of the activated carbon. In this way, the activated carbon fiber has the characteristics of double adsorption on the surface and large adsorption capacity, and can absorb dust and smoke in the air. , odor, odor, benzene, aldehydes, bacteria and other harmful substances. The organic pollutants adsorbed on the activated carbon fiber are catalyzed by the photocatalyst that is also distributed on the surface of the activated carbon fiber, and the oxidation reaction is rapidly generated and decomposed into non-toxic and harmless substances. Secondly, the adsorption capacity of activated carbon fiber is 50-100 times higher than that of activated carbon, which will greatly improve the purification efficiency of the device. Thirdly, dual-wavelength UV lamps provide more comprehensive light energy than single-wavelength UV lamps, which is conducive to the degradation of more substances. Therefore, this composite structure and the raw materials used are conducive to the photocatalytic oxidation reaction, and the purification effect is better.

Compared with the prior art, the beneficial effects of the present invention are:

1. The photocatalyst/activated carbon fiber composite structure is used, which is beneficial to the photocatalytic oxidation reaction, which is conducive to improving the adsorption efficiency and has a better purification effect on organic pollutants.

2. The use of dual-wavelength ultraviolet lamps, on the one hand, changes and destroys the organizational structure of microorganisms through the irradiation of ultraviolet rays on microorganisms, resulting in mutations in nucleic acid structures, making microorganisms lose their ability to reproduce and reproduce, and achieves the purpose of sterilization; Better lighting conditions can speed up the photocatalytic oxidation reaction, and the dual-wavelength ultraviolet lamp can effectively degrade more harmful organic substances and achieve the purpose of comprehensive disinfection.

3. It has the performance of continuously purifying the air

Since organic pollutants are continuously adsorbed and decomposed on the surface of activated carbon fibers, the device can continuously purify the air.

4. It can be used to absorb and decompose the toxic gas (such as formaldehyde) released by the wall coating or wall panel material of the new house, so as to achieve the effect of purifying the air in the room. For example, the side of the outer cover with pores is hung against the wall, and two kinds of ultraviolet light of different wavelengths are emitted to irradiate the photocatalyst air purification net and the photocatalyst/activated carbon fiber composite layer. Formaldehyde and other organic pollutants undergo photocatalytic oxidation on the surface of the photocatalyst and are transformed into non-toxic and harmless small molecular substances. At the same time, due to the adsorption of activated carbon fibers, the concentration balance of pollutants is destroyed, causing pollutants to diffuse into activated carbon fibers, and during the diffusion process, organic pollutants are oxidized and decomposed under the catalysis of photocatalysts.

5. It can be used for air purification in the dark space in the living room, such as the closed space in the furniture

The core of the device (that is, the part except the shell and the ultraviolet lamp) can be placed in a closed space in the furniture to absorb the released harmful gas. After the adsorption is completed, put the core in the outer cover, turn on the ultraviolet lamp, and irradiate for Hours, a photocatalytic oxidation reaction is generated to decompose the adsorbed harmful gas and achieve the purpose of purifying the air.

6. To beautify the indoor environment, you can design a beautiful appearance of the device and play a decorative role in the indoor environment.

This device can completely overcome the shortcomings of the existing indoor air purification technology, such as the serious dust diffusion of the adsorption material, which affects the indoor appearance; the spraying of chemical reagents is complicated, and the demand for auxiliary facilities is large, so it can hardly be used for the treatment of closed spaces of furniture. Due to the light source and no dust, the device not only can be used for indoor environment beautification and indoor air purification, but also can be used for purification treatment of volatile harmful substances and bacteria in furniture.
