Description
Technical field
The utility model relates to photocatalysis air-cleaning field, particularly a kind of novel tubular photocatalysis air cleaning device.
Background technology
The purification of air means that indoor air cleaner adopts comprise the technology such as electrostatic precipitation, anion, plasma, ozone, active carbon adsorption, photochemical catalytic oxidation (photocatalyst), photochemical catalytic oxidation refers to that the volatile organic matter such as formaldehyde, benzene homologues (VOC) is resolved into carbon dioxide and water by photochemical catalyst under action of ultraviolet light, in numerous air purifying process, photocatalysis oxidation technique can decompose the harmful substance in air thoroughly because of it, do not produce secondary pollution, and become the technology of most environmental protection and most prospect, and be subject to extensive concern.
At present, structural design market adopting the air purifier of more photocatalysis oxidation technique generally adopt is: photocatalyst catalyst coat is in mesh carrier, this mesh carrier is built in air purifier with structure that is dull and stereotyped or plane, ultraviolet lamp tube as photocatalysis oxidation reaction initator is built in directly over next-door neighbour's mesh carrier or positive side, the air stream entering air purifier passes perpendicularly through the mesh carrier of catalyst coat, and there is photocatalysis oxidation reaction under the action of uv light, air is purified.This structure has following defect: because light-catalyzed reaction betides catalyst coat surface, and high-speed air flow can instantaneously by the mesh carrier of catalyst coat, and the photocatalysis oxidation reaction time is short, and therefore the efficiency of purified treatment is not high, and clean-up effect is bad.In addition, traditional traditional tubular photocatalysis reactor, ultraviolet source is positioned on the axis direction of reactor outer tube, and the photochemical catalyst on reactor outer tube wall is subject to uniform illumination, can ensure light-catalyzed reaction speed faster.But this structure also has its obvious shortcoming: (1), due to the restriction by size of outer tube, the effective light-catalyzed reaction area in tubular reactor is obviously not enough, makes ultraviolet source utilization rate not high; (2) spacing of the ultraviolet source on tube axial direction and reactor outer tube needs considered critical, can cause managing interior most of air-flow when arranging unreasonable and not contact just direct outflow reactor with photochemical catalyst, make the reaction-mass-transfer efficiency of photocatalyst surface low.How to address these problems, will directly affect the actual application value of tubular photocatalysis reactor.
Summary of the invention
The utility model relates to a kind of novel tubular photocatalysis air purifying device, the shortcoming that its feature is to overcome that effective light-catalyzed reaction area in the reactor that exists in the design of existing tubular photocatalysis reactor is not enough, interior short stream easily appears manage in reacting gas by light source and irrational impact of outer tube pitch arrangement, provide a kind of effective affecting acreage greatly, strong, the simple tubular photocatalytic air purifier of structure of ultraviolet source utilization rate reaction-mass transfer ability that is high, photocatalyst surface.
To achieve these goals, the technical scheme adopted is: a kind of novel tubular photocatalysis air cleaning device, comprise outer tube, tube stand, ultraviolet lamp tube, ultraviolet lamp tube is fixed on outer tube by tube stand, it is characterized in that: outer tube wall is coated with nanosized TiO_2 layers of photo-catalytic material, also be provided with foliated air in outer tube and stream thing, air streams thing surface and also scribbles nanosized TiO_2 catalysis material, and described air streams thing and is sleeved on ultraviolet lamp tube.
Further, described air streams thing and is made up of multistage fan shape unit, and the number of blade of each fan shape unit is identical, and between adjacent cells, circumferential misalignment is arranged, and namely the blade of two adjacent cells is not at grade.
Further, the blade that described air streams thing (5) is porous plate or spiral plate.
Further, described outer tube is metal material.
Compared with prior art, the tubular photocatalysis air cleaning unit that the utility model provides streams thing extend the flow distance of reacting gas in clarifier by arranging foliaceous, increase the effective area of light-catalyzed reaction, improve ultraviolet source utilization rate, substantially increase purification efficiency and the effect of clarifier on the whole.

Detailed description of the invention
A kind of novel tubular photocatalysis air cleaning device, comprise outer tube 1, tube stand 2, ultraviolet lamp tube 3, it is inner that ultraviolet lamp tube 3 is fixed on outer tube 1 by tube stand 2, it is characterized in that: outer tube 1 inwall is coated with nanosized TiO_2 layers of photo-catalytic material 4, also be provided with foliated air in outer tube 1 and stream thing 5, air streams thing 5 surface and also scribbles nanosized TiO_2 catalysis material, and described air streams thing 5 and is sleeved on ultraviolet lamp tube 3; Air streams thing 5 and is made up of multistage fan shape unit, and the number of blade of each fan shape unit is identical, and between adjacent cells, circumferential misalignment is arranged, and namely the blade of two adjacent cells is not at grade; The blade that air streams thing 5 is porous plate or spiral plate; Outer tube is metal material.
The course of work of the present utility model is such, air to be processed is needed to enter purifier through import, under the effect of irradiation of ultraviolet lamp tube 3, the nanosized TiO_2 that harmful substance in air and air stream on the blade surface of thing 5 and outer tube wall is had an effect, oxidation Decomposition, the air after purified treatment is discharged through pipe-type outlet.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
