[0026] Embodiment 1:

[0027] Refer to Figure 1 、 Figure 3 、 Figure 4 、 Figure 5The utility model relates to a kind of photocatalytic tubular continuous reactors, including pedestal 1, still including: fixedly installed double-layer quartz tube 2 on pedestal 1, wherein, double-layer quartz tube 2 is arranged in S type, double-layer quartz tube 2 one end is fixedly connected with feed pipe 201, other end is fixedly connected with discharge pipe 202;Sleeve 3 is sleeved on double-layer quartz tube 2, and it is coaxially arranged with double-layer quartz tube 2;Driving assembly is arranged on double-layer quartz tube 2, and it is used to drive sleeve 3 rotation;Multiple catalytic lamps 302 are circumferentially equidistantly distributed in sleeve 3, and are all detachably connected on the inner wall of sleeve 3.

[0028] Support ring 4 is fixedly installed on double-layer quartz tube 2, limit ring 402 is integrally formed on the inner wall of support ring 4, limit groove 401 is formed on sleeve 3, limit ring 402 is rotationally connected in limit groove 401, and the size of the inner diameter of support ring 4 and the outer diameter of sleeve 3 is same.

[0029] Driving assembly includes motor 5, gear 502 is fixedly connected on the output end of motor 5, gear ring 503 is fixedly connected on sleeve 3, gear ring 503 is engagedly connected with gear 502, and motor 5 is fixedly installed on support ring 4 by support frame 501.

[0030] When using, raw materials enter into double-layer quartz tube 2 in S type from feed pipe 201, due to the design of S type, the flow path of raw materials in pipe is lengthened, and the residence time of raw materials in photocatalytic area is increased.Meanwhile, motor 5 is started, drives gear 502 on its output end to rotate, gear 502 is engaged with gear ring 503 on sleeve 3, thereby driving sleeve 3 to rotate around the axis of double-layer quartz tube 2, and simultaneously, multiple catalytic lamps 302 circumferentially equidistantly distributed in sleeve 3 are rotated with sleeve 3, and flow raw materials in double-layer quartz tube 2 from different angles are irradiated, and the specific wavelength light emitted by catalytic lamp 302 is absorbed by photocatalyst in double-layer quartz tube 2, and electron-hole pair is excited, and these electron-hole pairs have oxidation-reduction reaction with raw material molecules, thereby making raw materials have photocatalytic chemical reaction, and converting into product, and then product is discharged from discharge pipe 202 with the flow of raw materials;

[0031] Meanwhile, rotating sleeve 3 drives catalytic lamp 302 to irradiate raw materials from multiple angles, greatly reduces light dead angle, not only improves the utilization rate of light and the efficiency of photocatalytic reaction, but also helps to improve the yield of product and the conversion rate of reaction;

[0032] Meanwhile, through the rotation of sleeve 3, the irradiation of catalytic lamp 302 can be more evenly distributed on raw materials in double-layer quartz tube 2, avoids the situation that part of raw materials is not completely reacted or overreacted due to uneven irradiation, thereby improving the uniformity and stability of reaction, and being beneficial to obtain product with more stable quality.

[0033] Example 2:

[0034] Referring to Figure 3 A photocatalytic tubular continuous reactor is basically the same as that in Embodiment 1, and further, a protective shell 6 is detachably connected to the base 1, and the double-layered quartz tube 2 is located in the protective shell 6, and a handle 601 is fixedly installed on the protective shell 6;

[0035] By arranging the protective shell 6, the double-layered quartz tube 2, the sleeve 3, the catalytic lamp 302 and the driving assembly and other components are enclosed in the protective shell 6, thereby playing a protective role.

[0036] On the one hand, the protective shell 6 can prevent dust, sundries, moisture and the like from entering the interior of the reactor, thereby avoiding pollution, short circuit or damage and the like to the photocatalytic reaction and the equipment components, and on the other hand, for some cases of catalytic reaction using specific wavelength light, the protective shell 6 can prevent light leakage, improve the utilization rate of light, and also avoid potential light damage to the operator.

[0037] Further, a plurality of mounting bolts 602 are arranged, and the protective shell 6 is detachably connected to the base 1 through the plurality of mounting bolts 602;

[0038] When it is necessary to overhaul, maintain or replace the components in the interior of the reactor, the operator can hold the handle 601, unscrew the mounting bolts 602, and detach the protective shell 6, so as to perform subsequent overhauling, maintaining or replacing operations.

[0039] Embodiment 3

[0040] Referring to Figure 5 A photocatalytic tubular continuous reactor is basically the same as that in Embodiment 1, and further, a mounting seat 301 is arranged, the catalytic lamp 302 is fixedly installed on the mounting seat 301, and the mounting seat 301 is detachably connected to the inner wall of the sleeve 3 through a plurality of fixing bolts 303;

[0041] The catalytic lamp 302 and the sleeve 3 are detachably connected through the mounting seat 301 and the fixing bolts 303, thereby facilitating installation, detachment and replacement of the catalytic lamp 302;

[0042] When the catalytic lamp 302 appears to be faulty, needs to be upgraded or needs to be replaced by a catalytic lamp 302 of different wavelength, the fixing bolts 303 can be quickly unscrewed, the old catalytic lamp 302 can be taken out and a new one can be installed, thereby greatly shortening the maintenance and downtime of the equipment and improving the production efficiency.

[0043] Embodiment 4

[0044] Referring to Figure 1 , Figure 2 , Figure 6A photocatalytic tubular continuous reactor is basically the same as that in Embodiment 1, and further, a support cylinder 7 is symmetrically fixed and installed at each end of the base 1;

[0045] Further, a screw rod 701 is threadedly connected in the support cylinder 7, and a support disc 702 is fixedly installed at an end of the screw rod 701 away from the support cylinder 7, and a nut 703 is fixedly installed at an end of the screw rod 701 close to the support disc 702;

[0046] When the height or levelness of the reactor needs to be adjusted, an operator uses a wrench to hold the nut 703, and rotates the nut 703 to drive the screw rod 701 to rotate, at this time, the screw rod 701 will produce axial displacement in the support cylinder 7 to realize the action of rising or falling, and with the movement of the screw rod 701, the relative position between the support disc 702 and the placement surface changes, thereby changing the height and horizontal posture of the whole reactor;

[0047] When the reactor reaches the required height and levelness, the rotation of the nut 703 is stopped, at this time, the friction between the support cylinder 7 and the nut 703 and the self-locking characteristics of the thread can keep the position of the screw rod 701 fixed, and ensure that the reactor maintains a stable height and horizontal state in the subsequent operation process, avoids problems such as uneven distribution of raw materials and inconsistent illumination effect caused by the inclination of the equipment, thereby improving the efficiency of the photocatalytic reaction and the consistency of the product.
