DETAILED DESCRIPTION

[0020] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0021] In specific implementation, as shown in the drawings, Figures 1-4 A catalytic oxidation device for in-situ regeneration of activated carbon includes an activated carbon plate 100 loaded with titanium dioxide and a square tube 200, the activated carbon plate 100 is installed inside the square tube 200; a processing mechanism 300 is arranged above the square tube 200 and is used for catalytic oxidation treatment of the activated carbon plate 100; wherein the processing mechanism 300 includes a group of ultraviolet lamps 310 and a group of glass plates 320, the glass plates 320 are arranged in an inclined manner, and adjacent two glass plates 320 are arranged in a mirror image symmetry.

[0022] As shown in the drawings, Figure 1 and Figure 2 The upper part of the square tube 200 is provided with a mounting box 210, a butt joint 220 is arranged between the mounting box 210 and the square tube 200, and a plug valve 230 for closing the butt joint 220 is installed on the mounting box 210.

[0023] When the activated carbon plate 100 installed in the square tube 200 needs to be regenerated, the plug valve 230 can be opened, then the ultraviolet lamp 310 and the glass plate 320 are placed into the square tube 200 along the butt joint 220, and then the ultraviolet lamp 310 is started to operate, part of the irradiation light directly irradiates to the activated carbon plate 100 loaded with titanium dioxide between adjacent two glass plates 320, and the remaining part of the light is refracted with the glass plate 320, so that the irradiation light performs oxidation reaction with the activated carbon plate 100 loaded with titanium dioxide at multiple points and multiple angles, then the irradiation light of the ultraviolet lamp 310 oxidizes and decomposes the organic matter on the activated carbon plate 100 under the reaction of the catalyst titanium dioxide, achieving the effect of regeneration.

[0024] As shown in the drawings, Figure 2 , Figure 3 and Figure 4 The processing mechanism 300 further includes a U-shaped frame 330, the U-shaped frame 330 is arranged inside the mounting box 210, an electric push rod 211 fixedly connected with the top of the U-shaped frame 330 is installed on the mounting box 210, the ultraviolet lamp 310 is installed on the inner wall of the U-shaped frame 330, and a support strip 331 connected with the glass plate 320 is arranged inside the U-shaped frame 330.

[0025] When the regeneration treatment is performed, the electric push rod 211 is used to drive the U-shaped frame 330 to enter the interior of the square tube 200, so that the ultraviolet lamp 310 is placed in the interior of the square tube 200, at this time, the support strip 331 drives the glass plate 320 to be placed in the interior of the square tube 200 and refracts the illumination light of the ultraviolet lamp 310, in the process, the catalytic oxidation component is transported into the square tube 200, without the active carbon plate 100 being transported and moved, so that the active carbon plate 100 is regenerated in situ, the dismounting and transportation time is saved, the equipment using the active carbon plate 100 is facilitated to operate in time, and the device is more practical.

[0026] As shown in Figure 3 and Figure 4 , the U-shaped frame 330 is slidably connected with a support shaft, one end of the support shaft extends to the outside of the support strip 331.

[0027] The support shaft is used to slidably support the support strip 331.

[0028] As shown in Figure 2 , Figure 3 and Figure 4 , the inner wall of the U-shaped frame 330 is provided with a motor 332, the output shaft of the motor 332 is provided with a cam 333 outside the support strip 331 through a shaft coupling, and the one end of the support strip 331 and the U-shaped frame 330 are provided with a spring 334, and the spring 334 is sleeved outside the support shaft.

[0029] During the operation of the ultraviolet lamp 310, the motor 332 is started to drive the cam 333 to push the outside of the support strip 331, and the spring 334 is used to reset the moved support strip 331, so that the support strip 331 drives the glass plate 320 to reciprocate, so as to change the light refraction point and increase the illumination range of the ultraviolet lamp 310.

[0030] As shown in Figure 2 and Figure 3 , the material of the glass plate 320 is quartz glass.

[0031] Since the quartz glass is mainly composed of silicon dioxide, the internal structure is relatively simple and uniform, the structure has less scattering and absorption of the light emitted by the ultraviolet lamp 310, the light emitted by the ultraviolet lamp 310 can pass through and be refracted more smoothly, and the illumination range of the ultraviolet lamp 310 is improved.

[0032] Working principle: before the active carbon plate 100 is installed, the active carbon plate 100 is placed in the prepared precursor solution, which is prepared by mixing tetrabutyl titanate and ethanol in a volume ratio of 1:10, and then adding a small amount of nitric acid. The immersion time is determined by the properties of the active carbon plate 100 and the required load. After immersion, the active carbon plate 100 is taken out and dried to remove the solvent. Then calcine at high temperature to decompose the precursor into titanium dioxide. Subsequently, the active carbon plate 100 loaded with titanium dioxide can be installed in the appropriate position of the square tube 200;

[0033] When the active carbon plate 100 needs to be regenerated after long-term use, the plug-in valve 230 can be opened, and then the ultraviolet lamp 310 and the glass plate 320 are placed in the square tube 200 along the butt joint 220. Then start the ultraviolet lamp 310 to operate, part of the irradiation light directly irradiates the active carbon plate 100 loaded with titanium dioxide between the adjacent two glass plates 320, and the remaining part of the light is refracted with the glass plate 320 to make the irradiation light oxidize the active carbon plate 100 loaded with titanium dioxide at multiple points and multiple angles. During the reaction process, the motor 332 is started to drive the cam 333 to move in conjunction with the spring 334, so that the support bar 331 drives the glass plate 320 to reciprocate, thereby changing the light refraction point and increasing the light range of the ultraviolet lamp 310, improving the utilization rate of the catalyst titanium dioxide, thereby ensuring the regeneration effect. Subsequently, the ultraviolet lamp 310 irradiation light is oxidized and decomposed on the active carbon plate 100 under the action of the catalyst titanium dioxide, achieving the regeneration effect. During the entire regeneration process, the active carbon plate 100 does not need to be disassembled and transported for in-situ regeneration treatment.

[0034] It should be noted that the active carbon plate 100 loaded with titanium dioxide can also be used for normal installation of the normal active carbon plate 100, and the titanium dioxide is arranged in the appropriate position of the square tube 200 to ensure that the regeneration reaction proceeds normally.

[0035] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution. The description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be combined to form other embodiments that can be understood by those skilled in the art.
