Description
Technical field
The present invention relates to a kind of personal cabin ventilation lighting devices more specifically will utilize light the present invention relates to a kind of
The personal cabin ventilation illumination dress that the principle of catalyst combines the purification of the air in ventilation shaft with the illumination of personal cockpit
It sets.
Background technique
The air quality of seating plane cockpit directly influences the comfort of passenger, data show that the bad meeting of air quality
So that the generally existing fatigue of crew and passenger, headache and the problems such as have sore throat.On the other hand, it is adopted to save the energy
It is tighter that the air that cockpit is discharged is imported the problem of cockpit is aerated, makes air quality by air recycle system again
Weight.
It is well known that photocatalyst is a kind of under the irradiation of light, itself does not change, but can promote chemical reaction
Substance.Photocatalyst can make the adsorbed oxygen of material surface and water activity under the irradiation of light, and generating has oxidability pole
Oxidation reaction occurs for strong free hydroxy and active oxygen, so that organic matter, bacterium, virus etc. are thoroughly decomposed into carbon dioxide
And water.
Photocatalyst air purifying technology is the desirable technique currently curbed environmental pollution in the world.Wherein, photocatalyst purifies
Key whether excellent effect be just to improve to a greater degree pollution air and photocatalyst contact area and can
Guarantee that photocatalyst surface obtains enough light irradiations to a greater degree.In addition, above-mentioned photocatalyst not only can be through irradiation purple
Outer light and the photocatalyst excited are also possible to touch by irradiating the light that other light (such as visible light) excite
Matchmaker.
In addition, existing photocatalyst purification plant can be divided mainly into single channel formula by structure, single channel type expands surface-type,
Honeycomb runner superposing type and expansion light-source type these types type.Hereinafter, by being carried out briefly to each type of device respectively
It is bright.
(1) single channel formula
Single channel formula structure is typical photocatalyst device structure.It only include one in the photocatalyst device of single channel formula
A runner, runner wall surface are coated with photocatalyst coating, and in runner center arrangement ultraviolet radiator, light is realized by excitation photocatalyst
Catalytic oxidation process.
The gold of Shanghai University of Science and Technology is peaceful et al. by primary filter, high efficiency filter, active carbon filtering and photocatalyst oxidation catalyst filter
A device is integrated into be studied.The structure of this integrating device 1A is as shown in Figure 1.Air by cylindrical drum 10A side wall
10A1 enters, under the action of being set to internal blower 20A, air can successively pass through multiple filtration net (primary efficient filter screen 30A,
HEPA high efficiency particulate air 40A, activated charcoal strainer 50A), reach internal layer is attached with TiO2On the strainer 60A of (photocatalyst).By
There are the double fluorescent tube 70A of ultraviolet light in the center arrangement of the cylindrical drum 10A in integrating device 1A, therefore, photocatalyst is in excited state,
Thus polluted gas realizes air cleaning using multi-filtering by redox reaction can occur when photocatalyst on the whole
Process.
But as shown in Figure 1, the shortcomings that single channel formula be to pollute air and photocatalyst (TiO2) contact area it is small,
Therefore, the response area to react is also smaller.
(2) single channel type expands surface-type
As noted previously, as the response area of the photocatalyst device of single channel formula is smaller, therefore, in order to improve pollution air
With the response area of photocatalyst, proposes single channel type and expand surface-type structure wherein, above-mentioned single channel type expands surface-type knot
Structure is on the basis of single channel formula structure, using the carrier of other forms, to replace simple runner wall surface as light
The attaching surface of catalyst.This mode increases the surface area of photocatalyst, and thus, it is possible to improve the reaction efficiency of device.
Yan Qinian et al. studies the photocatalyst device of water conservancy diversion convolution air duct form.This water conservancy diversion convolution air duct shape
The structure of the photocatalyst device 1B of formula is as shown in Figure 2.Relative to the photocatalyst device of single channel formula, this water conservancy diversion convolution air duct shape
The photocatalyst device 1B of formula uses partition (not shown), forms helical flow path 20B.TiO2Coating (photocatalyst coating) is in addition to spraying
Except on duct wall 11B, also spraying is attached on partition, thus improves response area.Four (illustrate only two herein
Branch) ultraviolet lamp tube 31A, 32A of different radiation wavelength be arranged in device central axial line direction, resonance light source thus is formed, with
Photocatalyst is set to be in high-intensitive excited state.In the photocatalyst device 1B of water conservancy diversion convolution air duct form shown in Fig. 2, due to stream
Road length has with coating area largely to be expanded, and therefore, the two factors also become the key of reaction efficiency raising.
In addition, Zhao Gang is the photocatalyst device that passenger train devises screen type, structure is as shown in Figure 3.This silk screen
The photocatalyst device 1C of formula is installed on air return pipeline (not shown), in flat drawer-type structure.The outlet of runner and entrance
Distance is smaller, and two end faces are respectively disposed with one metal wire layer web frame.TiO2Coating (photocatalyst coating) is attached on silk screen,
Reached excited state by after two ultraviolet lamp tube 10C irradiation of runner intermediate arrangement.Due to the special shape requirement of this device,
So that its coating is arranged in vertical run direction, it is also contemplated that runner can not be blocked, therefore screen net structure is used.But silk screen
Structure is limited to area expansion, and not ideal carrier form, causes the once-through reaction efficiency of device lower.Therefore, Fig. 3 institute
The structure of the photocatalyst device 1C of this screen type shown is only applicable to repeatable return air and the lower situation of polluted gas concentration.
In addition, Dan Xinggang et al. has carried out light-catalysed experimental study.The experimental provision that the research uses is glass pipe sleeve
The structure type of cylinder, installs ultraviolet lamp tube in the quartz ampoule of internal layer, fills small bead in the glass tube sleeve of outer layer
Grain.By TiO2(photocatalyst) is attached on small bead with coating form spraying, and is formed as the form of packed bed, and thus, it is possible to big
Width expands response area.
But the photocatalyst device of the single channel type of above-mentioned three kinds of situations expansion surface-type has the following disadvantages: and is flowing
The air flowed in road will receive biggish flow resistance, in the field of ventilation more sensitive to flow resistance, such as leading to for the vehicles
In wind system, it is likely that be unsatisfactory for flow resistance requirement.
(3) honeycomb runner superposing type
Honeycomb flow passage structure is same as surface-type structure is expanded, and is provided to increase reaction surface and propose.But by
It is more intensive in honeycomb runner, ultraviolet source can not be arranged inside each runner, it therefore, can only entrance in channel and outlet
Place ultraviolet lamp tube in position.Furthermore, it is contemplated that the limitation of the range of exposures of light, runner is not again too longly settable, as a result,
There have been the structures for the so-called honeycomb runner superposing type that shorter honeycomb flow passage structure is superimposed with ultraviolet lamp.
Beijing Institute of Aeronautics Wang Jun seminar just belongs to this honeycomb runner superposing type for the photocatalyst device 1D that airliner cabin designs
Structure, structure is as shown in Figure 4.Using the purpose of honeycomb runner, allow for and packed bed and metal mesh shown in Fig. 3
Etc. the structures of forms compare, the flow resistance of honeycomb flow channel type structure is much lower.In addition, by TiO2Coating (photocatalyst coating) 30D
Spraying is attached to the wall surface position of each honeycomb runner 10D, utilizes being superimposed for multiple groups ultraviolet lamp 20D and multiple honeycomb runner 10D
Structure can make the ultraviolet illumination condition in most of honeycomb channel 10D good, thus be able to achieve biggish reaction efficiency.
In addition, Lu Yuanwei et al. equally has studied this honeycomb runner superposing type structure.Used honeycomb runner laminate
Having a size of 300mm × 300mm, with a thickness of 6mm, honeycomb cell densities range is 250 × 250 units/m2.It is verified by calculating, research mentions
Honeycomb channel optimal aspect ratio is 1.5 out, under this structure proportion, it is ensured that light intensity is fully used.In addition, Gu Chang army etc.
People also studies this structure.Unlike Lu Yuanwei et al., Gu Changjun et al. uses ceramic network instead of gold
Belong to net, equally also achieves preferable experiment effect.
But the photocatalyst device of the honeycomb runner superposing type of above-mentioned three kinds of situations similarly has the following disadvantages: and is flowing
The air flowed in road will receive biggish flow resistance, in the field of ventilation more sensitive to flow resistance, such as leading to for the vehicles
In wind system, it is likely that be unsatisfactory for flow resistance requirement.
(4) light-source type is expanded
In addition to above-mentioned more conventional photocatalyst device type, also some researchers look for another way, by expanding to optical path
Mode make light distribution more uniform, so as to improve reaction efficiency.
Feng Qiaolian et al. is proposed using optical fiber as the idea for expanding light source, photocatalyst device 1E such as Fig. 5 of conception
It is shown.Optical fiber LF is inserted on the wheel hub H of blower BL instead of the blade of blower BL.And on the surface of optical fiber LF, then it is covered with
TiO2Coating.Wheel hub center arrangement has ultraviolet lamp tube 20E, and coating can be extended into for ultraviolet source by being distributed in radial fiber optic bundle
Light-catalyzed reaction occurs for position, excitation photocatalyst.But this idea is not through realization in kind, how actual effect needs
Verifying.
Leaf sword people then proposes with SiO2For the carrier of photocatalyst, manufactured photocatalyst device 1F is as shown in Figure 6.Experiment
When, it need to first prepare SiO2Three-dimensional framework, thereafter by TiO2Coating is attached on skeleton, and skeleton is disposed in the form of packed bed
Inside device.Carrier has been disposed about ultraviolet lamp tube.Since light source can pass through SiO2Extend optical path, therefore the light of this form
Catalyst also belongs to light source expanding type, has very great help to the raising of reaction efficiency.
In addition, the application of photocatalyst is concentrated mainly on civil field at present, for air in clean rooms, air matter is improved
Amount.In space industry, the control of polluted gas is at present still mainly using heat catalytic oxidation reactor.Specifically, it is
The polluted gas such as VOC are promoted to be oxidized by the way that gas to be heated to 300 DEG C~500 DEG C of high temperature, and by the effect of catalyst
For CO2And H2O.And in aviation field, the control of polluted gas is at present then still mainly using ozone converter to O3With VOC into
Row is handled, and the traditional high-temperature S removal reactor used in principle and space industry is similar, only meeting on reaction condition
There are some differences.
Meanwhile photocatalytic oxidation reactor is compared to traditional high-temperature S removal reactor, has that low energy consumption, structure letter
Single advantage, thus have a good application prospect.
By above-mentioned introduction it is found that still there can not be a kind of photocatalyst device in the past, can farthest improve
The contact area of air and photocatalyst is polluted, and can farthest guarantee that photocatalyst surface obtains enough light irradiations.
Therefore, how designing one kind can realize using the photocatalyst purification techniques for meeting above-mentioned condition and promote the people
It is become with the structure of the air quality of passenger plane cockpit as technical problem urgently to be resolved.
Simultaneously, it is also desirable to the above structure designed while can make to flow in the vent flow path for venting air flow
