Abstract
A photocatalysis air purification device for central air-conditioner pertains to the air purification field. The utility model comprises a shell, a filter screen, an ultra-violet lamp, and nanometer photocatalysis reaction networks; the nanometer photocatalysis reaction networks are provided on the windward cross-section and on the inner wall of the shell, the filter screen is provided on the air opening of the photocatalysis air purification device, the ultraviolet lamp is provided between the windward nanometer photocatylysis reaction networks. When air flows through the utility model, organic pollutants, malodor, bacteria and viruses in the air are caught by the nanometer photocatalysis reaction networks, and then are decomposed or killed. The utility model is applicable to the main pipe or the branch pipe of a central air conditioner with an aim of providing clean air for the using terminal of a central air conditioner.
Description
Technical field
The utility model relates to a kind of air purifier, and particularly a kind of central air-conditioning photoactivation air cleaning unit belongs to air purification field.
Background technology
Because the City Building syndrome that modern residential environment and interior decoration etc. cause, room conditioning disease, organic contamination etc. directly have influence on people's health and lives safety.Because of central air conditioner system can not be regular cleaning and sterilization, its internal system becomes the bacteria breed place and the environmental pollution that brings, paid more and more attention.Particularly since the cross-infection problem that the use of central air conditioner system produces communicable diseases receive much attention.People attempt is by the various effective ways quality that purifies air.The air purifying process that uses both at home and abroad mainly contains charcoal absorption technology, ozone purification technology, anion dedusting technology and high voltage electrostatic technique at present.The charcoal absorption technology can only store nuisance absorption, and can not be with its decomposition or removal.Therefore in case adsorb saturatedly, need to change sorbing material, and finally do not eliminate harmful substance, just pollution sources are 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. are caused.
Utilize photocatalysis that air is carried out the developing direction that purified treatment is current air pollution treatment technology.Find by literature search, China's utility model patent title: a kind of photocatalysis air cleaning device, the patent No.: 02235830.7, this patent disclosure a kind of a kind of photocatalysis air cleaning device that is used for central air-conditioning, the casing size equates with the central air-conditioning system that matches, and certainly will add the resistance of strong wind behind pack into ultraviolet lamp tube and photochemical catalyst; In addition, the photochemical catalyst of this device is to use magnetically controlled sputter method attached on the carrier, and specific area is little, and the light irradiated area is limited.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, a kind of have high adsorption and highly active central air-conditioning photoactivation air cleaning unit are provided, this device can be used for the air cleaning of central air-conditioning, make it remove airborne organic pollution, bacterium, virus etc. fast, effectively, safely, solved the problem that exists in the background technology.
The utility model is achieved through the following technical solutions, the utility model comprises: shell, screen pack, ultraviolet lamp tube, nano-photo catalytic reaction net, cross section (windward side) and shell at shell are provided with nano-photo catalytic reaction net on the inwall all around, these nano-photo catalytic reaction nets can both receive the ultraviolet ray of ultraviolet lamp tube, photocatalysis air cleaning device air intake vent place is provided with a screen pack, dust in the filtered air and suspended particulate.
The shell sectional dimension is bigger than the sectional dimension of the airduct that is connected with it, and the two ends of shell are by tubaeform shell transition, and available flange is connected it with the airduct of front and back.Shell after this amplification can reduce the drag losses that causes owing to the nano-photo catalytic reaction net of installing in the reaction unit.
According to the size of cross section, ultraviolet lamp tube places between the windward side nano-photo catalytic reaction net, perhaps is arranged at the axial location in the photocatalysis air cleaning device body.In order to increase the irradiation intensity of ultraviolet light to the windward side of shell and the net of inwall nano-photo catalytic reaction all around, ultraviolet lamp tube U type or convex ultraviolet lamp tube.
Nano-photo catalytic reaction net is made by wire netting immobilized particles shape nano-photocatalyst.Made light-catalyzed reaction net can be tabular and tubbiness, and purifying net and inwall purifying net are used as facining the wind.The characteristics of this light-catalyzed reaction net are that specific area is big, gas-flow resistance is little, and corrosion-resistant, good endurance.The air that enters photocatalysis air cleaning device enters the nano-photo catalytic reaction chamber behind the net filtration earlier after filtration, by the nano-photo catalytic reaction net of inwall around the windward side of being fixed in shell and the shell with various nuisances absorption after, removing because of being subjected under the right oxidation-reduction in the formed free electron of UV-irradiation-electronics hole it is decomposed, thereby realizing the purpose of purification.
When the utility model flow through when air, nano-photo catalytic reaction net was seizure such as the organic pollution in the gas, stench, bacterium, viruses, and with its decomposition or kill.During the utility model can be used for the house steward in the central air conditioner system or is in charge of, provide the air of cleaning for the use terminal of central air conditioner system.
