The specific embodiment
As shown in Figure 1, B, C and E, F are respectively that M, N and G, H are respectively with half acceptance angle θ without the summit in compound parabolic concentrator 3 cross sections after brachymemma and the brachymemma processing
cWith brachymemma angle θ
dThe outermost light of incident and the intersection point of compound parabolic concentrator 3.Tubular reactor 4 should be placed near involute summit P in the CPC as far as possible, receive with the maximum that realizes 4 pairs of CPC internal reflections of tubular reactor light, needs and cost according to real reaction are taken all factors into consideration, can do truncation to CPC, as the dotted line EF among Fig. 1, this moment, the optically focused of CPC descended than meeting, but cost also can decrease.
As shown in Figure 2, each figure is the convergence situation of different angles incident ray on composite parabolic formula concentrator 3 reaction tubes surfaces.Under best CPC reflection and tubular reactor 4 caliber conditions, after the one or many reflection, will effectively be absorbed by tubular reactor 4 with the sunray of all angles of maximum entrance half-angle incident.Tubular reactor 4 calibers should be suitable, too smallly then can't absorb reverberation fully, excessively then increases material cost and carry pressure drop, generally should be controlled between the 25-50mm.
Represent the relation of the reflectivity of compound parabolic concentrator 3 reflectorized material aluminium films used herein as Fig. 3 with lambda1-wavelength.As seen from the figure, the aluminium film reflectorized material of surface plating 2 μ m aluminium oxide can usable reflection less than the sunshine of 600nm for wavelength, therefore adopt the reactor of this reflective membrane should use photoresponse in the photoresponse interval photochemical catalyst below 600nm.As the photochemical catalyst that uses more long wavelength's response then should use the alternately reflective membrane of argent and aluminium.
As shown in Figure 4, compound parabolic concentrator CPC is with a determining deviation parallel arrangement, and concrete spacing is selected and can be determined according to actual site area, is installed on the stainless steel stent 1 with East and West direction, and the inclination angle a of support is as the criterion with the latitude of locality, towards Due South to putting; Can adjust the angle of CPC sensitive surface by adjusting screw(rod) 2, can in one day, repeatedly regulate, the CPC opening is remained in the apparent motion of the sun.The inclination angle of CPC support gets final product several times in the adjusting of 1 year intercycle.It is relevant with the entrance half-angle of CPC to regulate number of times, half acceptance angle θ of the visible composite parabolic formula of physical relationship concentrator 3
cWith 1 year in the relation table (table 1) that requires of periodic adjustment number of times.By this table as can be seen, θ
cMore little, it is many more to need to regulate number of times in 1 year, so θ
cShould be according to the suitable selection of specific requirement.Tubular reactor 4 is fixed on bearing 9 on the focal line of CPC in the CPC, and each tubular reactor 4 connects successively with PVC flexible pipe snake type, requires its number of changeable according to reaction scale.Add certain mass concentration photocatalyst powder and light-catalyzed reaction liquid to charging and discharge system 6, system is in the driving current downflow of circulating pump 5, flow velocity control makes Reynolds number between 10000-50000, avoids it to deposit in reactor tube walls with the abundant suspension that guarantees photocatalyst powder.
Table 1
As shown in Figure 5, CPC constitutes composite parabolic by reflective surface 8, and is supported by bearing 9 and Holder Fasteners, and reflective surface 8 is made up of the fiberglass support curved surface and the aluminium film of the shape that adheres to specification, be suppressed with the aluminium film on fiberglass support curved interior surface, there is the oxidation aluminium coat on the surface of aluminium film.Bearing 9 is fixed in tubular reactor 4 on the CPC focal line.
Compound parabolic concentrator (CPC) the 3rd according to rim ray principle design, can be designed the concentrator of different optically focused ratios according to designing requirement and tubular reactor 4 calibers.The schematic diagram of CPC and tubular reactor 4 combinations is seen Fig. 1.Extinction characteristic according to photochemical catalyst can be at the different reflectorized material of CPC plating inner surface; photochemical catalyst for ultraviolet light response uses the surface that the reflective aluminum film of protective layer of alumina is arranged, and can use the alternate plating of aluminium film or silver and aluminium for visible light responsive photocatalyst.
The material of tubular reactor 4 can have different choice according to the difference of photochemical catalyst, to select quartz glass for use based on the photochemical catalyst of ultraviolet response with height ultraviolet light permeability, and select the pyrex Pyrex glass of visible light permeability for use for having visible light-responded photochemical catalyst, iron content should remain on below the 100mg/kg in the glass, to avoid its absorption to solar ultraviolet light.Caliber is selected should be moderate, too high or too low effective absorption that all can't guarantee photochemical catalyst to sunray, and tubular reactor 4 diameters should be controlled between the 25-50mm.Absorption and the refraction of glass to light will take place during by tubular reactor 4 tube walls in light, influence convergence of rays, so tube wall should be controlled in the 1.4mm.Liquid in pipe is carried also should reach certain flow rate, makes Reynolds number between 10000-50000, and guarantee system is in turbulent condition, avoids the deposition of photochemical catalyst at inside pipe wall.
Compound parabolic concentrator CPC adopts the East and West direction array, tubular reactor 4 with the compound parabolic concentrator CPC focal line center of circle by bearing fixing in CPC inside, can adopt serial or parallel connection to connect according to the real reaction demand.Adopt mechanical diaphragm formula circulating pump that the catalyst and the aqueous solution that contains the finite concentration sacrifice agent are circulated in coiled reactor 4, photochemical catalyst is subjected to optical excitation generation light-catalyzed reaction in this process.For guaranteeing of maximum convergence and the absorption of CPC concentrator, the sensitive surface of CPC is remained within the apparent motion of the sun, so CPC should be that the inclination angle south orientation is installed placement with the local latitude to sunray.The optically focused of general CPC is more littler than big more then its opening, then needs the number of times regulated many more in 1 year.Take all factors into consideration the best CPC design parameter of selection according to local actual sunshine situation and reaction requirement, and make its optically focused as far as possible than increasing.
