Description
Technical field
The present invention relates to a kind of air cleaner, especially a kind ofly utilize light-catalyzed reaction that airborne harmful gas is carried out purified treatment and have the photocatalysis air purifying device of sterilization functions, belong to air purification field.
Background technology
Global environmental pollution and ecological disruption have forced people to give enough concerns to environment.Wherein because the atmospheric pollution that the discharging of industry, the vehicles etc. causes directly has influence on quality of life of people and healthy.Simultaneously, the City Building syndrome that causes owing to modern residential environment and interior decoration etc., room conditioning disease, organic contamination etc. directly have influence on people's health and lives safety.People's attempt is by various effective ways purifying ambient air quality.With regard to indoor air purification, the air purifier that uses both at home and abroad mainly adopts activated carbon adsorption technology, ozone purification technology, anion dedusting technology and high voltage electrostatic technique at present.The activated carbon adsorption technology can only store nuisance absorption, and can not be with its decomposition or removal.Therefore in case adsorb saturatedly, need to change adsorbing material, and finally do not eliminate harmful substance, just polluter is shifted.Ozone technology has sterilization, deodorization, but low to the removal efficient of organic pollution.It should be noted that more ozone itself is harmful to human body and environment.Utilize ozone technology to purify the air of a room, people must wait and just can enter the room behind certain hour after the shutdown.Anion and high voltage electrostatic technique are a kind of physical action processes, can remove airborne flue dust, but can't remove purification to the pollution that chemistry, biology and microorganism etc. cause.
Utilize photocatalysis that air is carried out the developing direction that purified treatment is current air pollution treatment technology.Find that by literature search China Patent No. is: 99229554.8, name is called: the light catalytic purifying device, this patent disclosure a kind of light catalytic purifying device, its photocatalyst is a kind of Attraction block, it is bad not only to exist breathability, and lighting effect is not good enough yet.
Summary of the invention
The objective of the invention is at the deficiency that exists in the background technology, a kind of have photocatalyst good endurance, active high, photocatalysis air purifying device that light irradiance is big are provided, can be used for the air cleaning in places such as cleaning indoor and garbage disposal plant that environment is more abominable, garage of air, make it can remove airborne organic pollution, antibacterial, stench etc. fast, effectively, safely.
The principle of pollutant is in the PHOTOCATALYTIC AIR-PURIFYING: the energy gap (E that is equal to or greater than semi-conducting material when its light quantum energy (hv)
g) illumination when being mapped to semiconductor light-catalyst, in conduction band, form a free electron simultaneously, in valence band, form an electronics hole.If this electronics-hole to can effectively be separated and localization when some position of catalyst surface, then oxidation or reduction are adsorbed on harmful gas molecule on the catalyst surface effectively, and are translated into innocuous substances such as diverse water of chemical property and carbon dioxide.
The present invention is achieved by the following technical solutions, the present invention mainly comprises: blower fan, airstrainer, light-catalyzed reaction chamber, body, its connected mode is: body air outlet place and air intake vent place respectively are provided with airstrainer, be light-catalyzed reaction chamber and blower fan between two airstrainers, the light-catalyzed reaction chamber is made up of loaded nano light-catalyzed reaction sheet and ultraviolet lamp tube, interspersed ultraviolet lamp tube in the loaded nano light-catalyzed reaction sheet, ultraviolet lamp tube can be used straight light tube and U type fluorescent tube.
When wind direction is front and back when moving towards, blower fan is positioned at the front or the back in light-catalyzed reaction chamber, and the position of light-catalyzed reaction chamber and blower fan can exchange.Wind direction is when moving towards from bottom to top, and blower fan is positioned at the bottom in light-catalyzed reaction chamber, and the air outlet place of fans entrance and body upper respectively is provided with an airstrainer.The light-catalyzed reaction chamber can combine with high-pressure electrostatic and plasma apparatus easily, thereby improves the comprehensive treatment capability of air cleaning.
Air outlet place and air intake vent place respectively are provided with drainage screen, and the airstrainer in exit also plays the effect of shielding of ultraviolet simultaneously.Wind direction flows and can flow and last current downflow front and back.Thereby, before and after the loaded nano light-catalyzed reaction sheet of light-catalyzed reaction intracavity and ultraviolet lamp tube can be, arrange and be arranged above and below.
Loaded nano light-catalyzed reaction sheet, adopting foam metal, foamed ceramics or ceramic honey comb is carrier, utilize magnetron sputtering, sol-gel and dipping method, titanium deoxid film or nano-particle are carried on its surfaces externally and internally and get, its specific surface area is big, gas-flow resistance is little, and corrosion-resistant, good endurance.
To send into the nano-photo catalytic reaction chamber through the airstrainer filtered air by the machine inner blower, by after being fixed in nano composite photo-catalyst on the loaded nano light-catalyzed reaction sheet various nuisances being adsorbed to particle surface, because of being subjected under the right oxidation-reduction in the formed free electron of irradiation under ultraviolet ray-electronics hole, it is decomposed remove.Cleaned air passes is discharged from the gas outlet of body.Circulation constantly is removed the pollutant in the room air so repeatedly, thereby realizes the purpose of purification.
The present invention has substantive distinguishing features and marked improvement, and the present invention " gulps down contaminated air into " in the body and " spues " after purifying again, and photocatalyst is good stability and harmless inorganic matter on the loaded nano light-catalyzed reaction sheet in addition, does not produce secondary pollution; The distinctive light-catalyzed reaction cavity configuration of the photocatalysis of nano combinedization and the present invention makes this depurator become the room air Good House keeping of organic pollution, sterilization and deodorization in a kind of efficient removal air.
