195；Chem.Eng.Sci.,2000,55:5089-5098), but its there is also following inferior position：Firstly, since above-mentioned macroscopical light is urged
Change the feature of reactor typically in more than 5cm, size is larger, and decay is serious when light passes through solution or catalyst granules, this meeting
Cause catalytic efficiency low, reaction liquid needs to circulate, reaction time length (>1h) etc..Secondly, the nanometer commonly used in such reactor is urged
Although catalyst particles effect is good, difficult separation and recycling and cost height.
The content of the invention
The shortcomings that it is an object of the invention to overcome prior art, there is provided a kind of characteristic size is between microreactor and macroscopic view
Small liquid-solid fluidized bed reactor between reactor and with higher average response speed.
The small liquid-solid fluidized bed reactor of photocatalysis of the present invention, it includes quartz ampoule and the glass being placed in quartz ampoule

Embodiment
Make below in conjunction with the accompanying drawings with the small liquid-solid fluidized bed reactor of photocatalysis of the specific embodiment to the present invention with detailed
Description.
The small liquid-solid fluidized bed reactor of photocatalysis of the invention as shown in Figure 1, it includes quartz ampoule 5 and is placed on
Bead 6 in quartz ampoule 5, catalyst film is loaded with the surface of the described inwall of quartz ampoule 5 and bead 6, be catalyzed
The carrying method of agent film uses existing method, such as sol-gal process, liquid phase deposition etc..It can be incited somebody to action by expanding reach 2
A certain amount of bead 6 is added in quartz ampoule 5.Inlet is provided with described quartzy bottom of the tube, at described inlet
It is provided with screen cloth 7 and is used as liquid distribution trough, described inlet is connected by pipeline with the outlet of micro-amounts of liquids syringe pump 3, in institute
There is expanding reach 2 to prevent catalyst granules to be carried at the top of the quartz ampoule stated, liquid discharge is provided with described expanding reach 2
Mouthful, outlet conduit is connected with for reacted liquid outflow reactor on described liquid outlet, in described quartz ampoule
Front is provided with light source 1, and Parabolic reflection shield 4 is provided with the rear of described quartz ampoule, and described is Parabolic
The directional light that light source 1 projects can be gathered in the focus of reflection shield by reflection shield, the axis and reflection shield of described quartz ampoule 5
4 focus overlaps.The length of described reflection shield is bigger than the length of quartz ampoule.Described light source 1 can be mercury lamp, xenon lamp or too
Sunlight.Parabolic reflection shield can be made by reflective aluminium sheet.
Described 5 preferable internal diameter of quartz ampoule is 1-10mm, wall thickness 1mm, the preferable a diameter of 20-200 μ of bead 6
m。
The parabolical equation of reflection shield is x2=40y, wherein x-axis are vertical with the incident direction of light, and -20mm≤x≤
20mm, 0≤y≤10mm, focus are (0,10mm), and the length of reflection shield is more slightly longer than quartz ampoule.The parabola of reflection shield can
To there is different selections, general reflection shield is bigger, and reaction effect is better.
In this embodiment, quartzy bore d=3mm, length 100mm, reflection shield length are 150mm.From methylene
Blue MB investigates the photocatalytic activity of the small liquid-solid fluidized bed reactor of photocatalysis as reactant.Photocatalysis shown in Fig. 1 is micro-
In the process of running, the power of xenon lamp is 200W to small liquid-solid fluidized bed reactor, at the beginning of the catalyst granules added in quartz ampoule
Beginning height of bed H0Respectively 0,5, the 10 and initial concentration C of 15mm, MB solution0For 20mgL-1, inject quartz from micro-injection pump 3
The flow Q of MB solution in pipe 5 is 0.450,0.675,0.900,1.125,1.350 and 1.575mLmin-1, each Q pairs of flow
The superficial liquid velocity u answeredLIt is 1.06,1.59,2.12,2.65,3.18 and 3.71mms respectively-1。
Comparative example 1：Inner surface of silica tube supported catalyst, glass bead surface not supported catalyst；
Comparative example 2：Inner surface of silica tube not supported catalyst, bead catalyst supported on surface.
Under different superficial liquid velocities, the small liquid-solid fluidized bed reactor of photocatalysis be used for degrade MB solution when degradation rate
As shown in Fig. 2 (a), Fig. 2 (b) Fig. 2 (c).In xenon lamp ultraviolet light content so it is low in the case of show very high light
Catalytic activity.As can be seen that although bead is not that (glass bead surface now does not have supported catalyst to catalyst from Fig. 2 (a)
Agent film, so be not catalyst, but the purpose for strengthening mass transfer can be played, reaction rate can also be improved), but bead plus
Enter and fluidize (initial height of bed H0=15mm) with being not added with bead (H0=0mm) compared to when degradation rate is increased 2-3 times, this
Aspect is due to the intensity of illumination that scattering of the bead to light increases that catalyst receives on inner surface of silica tube, it is often more important that
The fluidisation of bead significantly increases MB mass transfer rate, and the mass tranfer coefficient measured by benzoic acid dissolution method increases in 11-13
Times.As can be seen that the small fluidized-bed reactor of photocatalysis (initial height of bed H within the so short reaction time from Fig. 2 (b)0=
15mm, reaction time t=0.37min), it is shown that very high photocatalytic activity, this aspect are due to that catalyst granules carries
Supplied very big illuminating area, be on the other hand due to reactor size between microreactor and macroreaction device, compared with
Small size make it that illumination decay is small, and intensity of illumination is than more uniform.As can be seen that working as inner surface of silica tube and glass from Fig. 2 (c)
After glass bead surface all supported catalysts, the increase of illuminating area makes degradation rate further increase 5-35%.Fig. 3 is different spaces
Average response speed R under rate εav(initial height of bed H0=15mm), with the document (261-268 of Chem.Eng.J.101 2004；J
The 36-41 of Photoch.Photobio.A 225 2011) contrast, it is known that, the small liquid-solid fluidized bed reactor of photocatalysis it is flat
Equal reaction rate approaches with microreactor, but characteristic size (refers to the distance that light passes through in the reactor, referred to for pipe
Internal diameter) increase, the treating capacity of reactor is improved an order of magnitude.With document (Particuology 8 (2010) 60-
66；Chem.Eng.Sci.56 (2001) 1631-1638) contrast understand, compared with macroreaction device, photocatalysis is small liquid-solid
The average response speed of fluidized-bed reactor improves two orders of magnitude, meanwhile, its reaction time is several minutes, anti-far below macroscopical
Answer a few hours of device.
