Abstract
The invention discloses a wide waveband photocatalyst air cleaner, which comprises a container, wherein compound photocatalyst particles are arranged in the container. The container is prepared by sintering anion power, dolomite and pore-forming agent. The compound photocatalyst particles are prepared by sintering the anion power, tourmaline, maifanitum, nanometer titanium dioxide, cerous oxide and viscous pottery clay. The invention has the following great advantages: 1, the production rate of anions is high; and 2, no additional power supply is needed, and natural light can penetrate through a container wall and an air hole on the container wall to exchange with the surfaces of the compound photocatalyst particles so as to realize the purpose of purifying air, thereby bringing greatly convenience for use. The air cleaner in the invention can be arranged on desks, bedside tables and windows as well as in automobile and the like. The container can be made into various ornaments, such as egg-shaped, vase-shaped, animal-shaped, cartoon-shaped ornaments and the like, and has beautiful appearance and practical use.
Description
Technical field
The invention belongs to the daily living article field, specifically be meant a kind of (ultraviolet-infrared band all responds) photo-catalytic air cleaner that is placed on the wide-band response of removing airborne toxic and harmful in indoor or the automobile and improving the internal medium air.
Background technology
Photocatalyst also is photocatalyst, be one type with titanium dioxide (TiO
2) for representative, under the irradiation of light, self do not change, but can promote chemical reaction, have the general name of the semi-conducting material of catalysis.TiO
2As a kind of photocatalyst; Behind the ultraviolet in absorbing sunlight or lighting source; Redox reaction takes place under the exciting of ultraviolet energy; The surface forms the hydroxyl free radical and the ultra-oxygen anion free radical of strong oxidizing property, becomes harmless carbon dioxide and water to harmful substances in air and microbial decomposition, thereby reaches purpose such as the deodorization and sterilization that purifies air.But photocatalysis technology remains two problems at present, the one, and quantum efficiency is low, and the 2nd, TiO
2Only absorb the ultraviolet in the sunlight and since indoor ultraviolet a little less than, can not effectively produce photocatalysis.Therefore the photo-catalytic air cleaner of present indoor use generally need add a high tension generator and produce ultraviolet, reaches the purpose that purifies the air of a room.So increased cost undoubtedly, consumes energy, and use and limited to, as just not using in the automobile or in the wardrobe.Therefore, how to improve the quantum efficiency of photocatalysis system, it is infrared that the absorption spectrum of photocatalyst is extended to from ultraviolet, improves the utilization rate of luminous energy, is the target that these those skilled in the art pursue always.In addition, present photo-catalytic air cleaner anion generation is lower.
Summary of the invention
For overcoming the problem that above-mentioned prior art exists, the objective of the invention is to propose a kind of dispense with outer connecting power, directly utilize the photo-catalytic air cleaner of the wide-band response of nature luminous energy.And this depurator can produce the anion of higher needed by human body.
A kind of wide waveband photocatalyst air cleaner of the present invention comprises: container, container are built-in with the composite photo catalyst granule.It is characterized in that: said container is burnt till by anion powder, dolomite, pore former; Pore former is carbon or carborundum, and wherein the anion powder percentage by weight reaches 25-35%, and the dolomite percentage by weight reaches 35-45%; Pore former is a carborundum, and its percentage by weight reaches 30% or 35%; Pore former is a carbon, and its percentage by weight reaches 30%, and the perforation porosity of chamber wall reaches 30-40%.
Said composite photo catalyst granule is burnt till by anion powder, tourmaline, Maifanitum, nano titanium oxide, cerium oxide and viscosity potter's clay.Wherein the weight percent content of various raw materials is:
Advantage of the present invention is:
1. owing to contain transition elements, rare earth element, photocatalyst (nano titanium oxide), tourmaline in the composite photo catalyst granule; Therefore its energy gap forms from ultraviolet to infrared distribution; Thereby under infrared, ultraviolet, visible light or micro-natural radiation condition, all has the photocatalyst effect; Photocatalysis efficiency is greatly enhanced, and makes harmful poisonous organic and inorganic pollution resolve into nontoxic water and carbon dioxide.
2. because the two ends of tourmaline polar axis C have positive and negative charge respectively, and there is electric field in the surface, be similar to extremely son of electric coupling; Exist between granule and repel and attraction, mechanical lapping is added in the adding of rare earth element and nano titanium oxide, has formed the form of rare earth element and nano titanium oxide parcel tourmaline; When air molecule and enwrapped granule collision; The effect of highfield makes hydrone ionization, has increased airborne negative ion concentration, is of value to health of people.
3. owing to contain Maifanitum in the composite photo catalyst granule, increased the particulate degree of porosity of composite photo catalyst, effective contact area of luminous energy is increased, photocatalysis efficiency increases.
4. owing to all contain anion powder in container of the present invention and the photocatalyst particle, the amount that this anion powder discharges anion can reach 1500/cm
3, be that other any material is unapproachable, and "dead".This anion powder contains Mn, Cr, Co, Ni, Zn etc.; Than adopting many that single transition metal effect will be good; These d district metallic elements have the rank property of change; Can form an electron reaction chain, and, discharge more anion by the synergism of photocatalyst, tourmaline and rare earth element.
5. owing to the present invention the composite photo catalyst granule is placed in the container that is burnt till by anion powder, dolomite and pore former; Nature luminous energy sees through chamber wall and contacts with the particulate surface of composite photo catalyst with pore on the chamber wall and reach the purpose that purifies air; Need not additional power source; Bring great convenience to use, can be placed on the desk, on the bedside cabinet, on the windowsill, in the automobile etc.Container can be processed into various ornaments, like egg type, vase shape, animals shaped, cartoon shape etc.Both beautiful and practical.
