[0002] The ozone catalytic oxidation device may include a reaction tank and a catalyst filler. In the prior art, the catalyst filler is usually directly arranged on a supporting grid in the reaction tank to form a filler layer with the same horizontal cross-sectional area as the reaction tank. However, the whole-layer arrangement of the filler layer easily leads to uneven water and gas distribution in the reaction tank; at the same time, when the ozone catalytic oxidation device is used to treat liquor wastewater with high hardness, due to the large specific surface area of ​​the filler layer, during the effective contact between the wastewater, ozone and the catalyst filler, the catalyst filler is prone to scaling and hardening, thereby affecting the treatment effect of the ozone catalytic oxidation device on the liquor wastewater; furthermore, due to the limited working space in the reaction tank, it is inconvenient to handle the hardened catalyst filler. Utility Model Content

[0003] Based on this, the present application provides a packing structure and an ozone catalytic oxidation device to improve the problems in the prior art of uneven water and gas distribution, easy compaction and difficulty in handling after compaction caused by directly arranging the catalyst packing in a whole layer in the reaction tank.

[0012] In one embodiment, the first clamping position is set to a rectangular shape, and the bottom of the filling frame arranged in the first clamping position corresponds to the shape of the first clamping position. The second clamping position is set to a dovetail shape, and the bottom of the filling frame arranged in the second clamping position corresponds to the shape of the second clamping position.

[0028] Embodiment 1

[0029] The first embodiment of the present application provides a packing structure, which is applied to an ozone catalytic oxidation device. The ozone catalytic oxidation device further includes a reaction tank 400. The packing structure is arranged in the reaction tank 400. The packing structure includes:

[0030] The supporting square tube 100 is arranged horizontally, and a plurality of supporting square tubes 100 are arranged in parallel and at intervals;

[0031] A filling frame 200 is embedded in the supporting square tube 100 and can be detachably arranged. At least one filling frame 200 is arranged on each supporting square tube 100;

[0032] The catalyst packing is arranged in the packing frame 200 .

[0033] like Figure 1 As shown, in this embodiment, the ozone catalytic oxidation device can include a reaction tank 400 and a packing mechanism, wherein the packing structure is arranged in the reaction tank 400 for treating wastewater. During catalytic oxidation treatment, wastewater and ozone can pass through the packing frame 200 and contact the catalyst packing in the packing frame 200. The catalyst packing in this embodiment can be a modified aluminum-based ozone catalyst, and the ozone catalytic oxidation device can be used to treat liquor wastewater.

[0034] like Figure 1 and Figure 2 As shown, the packing frame 200 is arranged on the supporting square tube 100, and the packing frame 200 is detachably arranged on the supporting square tube 100. The supporting square tube 100 can be arranged in parallel and at intervals with a plurality of roots in the reaction tank 400, and the plurality of supporting square tubes 100 can be arranged at the same height position of the reaction tank 400. The plurality of supporting square tubes 100 can be arranged at equal intervals, that is, the intervals between two adjacent supporting square tubes 100 can be equal. The length of the supporting square tube 100 is determined by its position, and the maximum length of the supporting square tube 100 can be equal to the diameter of the reaction tank 400. The packing frame 200 on each supporting square tube 100 can be one or several. When the packing frame 200 is set to several, the plurality of packing frames 200 can also be arranged at equal intervals on the corresponding supporting square tube 100. The supporting square tube 100 and the packing frame 200 in this embodiment adopt the aforementioned arrangement method, so that the catalyst filler can be evenly distributed in the reaction tank 400.

[0035] It is understandable that the present application can realize modular setting of the packing structure by arranging the catalyst packing in the packing frame 200, and detachably arranging the packing frame 200 on the supporting square tube 100, thereby facilitating the uniformity of water and gas distribution. At the same time, since the specific surface area of ​​the packing structure in the present application is relatively small, the catalyst packing in the packing frame 200 is not prone to hardening. Even when the catalyst packing in the packing frame 200 is hardened due to scaling, the present application can also remove the packing frame 200 from the supporting square tube 100 to replace the catalyst packing in the packing frame 200, thereby conveniently maintaining the packing structure to ensure the treatment effect of the ozone catalytic oxidation device on liquor wastewater.

[0036] Specifically, a container clamping position 110 is provided on the supporting square tube 100 , and the filling frame 200 is arranged in the container clamping position 110 .

[0037] like Figures 2 to 4 As shown, in this embodiment, the container clamping position 110 can be a hole, a groove or other structure opened on the supporting square tube 100 for arranging the filling frame 200. The filling frame 200 at least partially extends into the container clamping position 110 so as to be detachably arranged on the supporting square tube 100. The filling frame 200 and the container clamping position 110 can be clearance-matched to facilitate the disassembly and assembly of the filling frame 200.

[0038] It is understandable that, in this embodiment, by arranging the filling frame 200 in the container clamping position 110 on the supporting square tube 100 , it is convenient to realize quick installation and removal of the filling frame 200 , thereby facilitating replacement of the catalyst filling in the filling frame 200 .

[0039] More specifically, the container clamping position 110 is disposed on the top of the supporting square tube 100 .

[0040] like Figures 2 to 4 As shown, in this embodiment, it is exemplarily explained that when the container clamping position 110 is set on the top of the supporting square tube 100, the container clamping position 110 forms a trough-shaped structure, and the trough of the container clamping position 110 faces upward. It is not difficult to see that at this time, the container clamping position 110 is non-through-through arranged on the supporting square tube 100 in the vertical direction.

[0041] It can be understood that, in this embodiment, the container clamp 110 is arranged on the top of the supporting square tube 100. Compared with the arrangement in which the container clamp 110 vertically penetrates the supporting square tube 100, this embodiment can reduce the impact of the container clamp 110 on the structural strength of the supporting square tube 100, so that the supporting square tube 100 has a relatively high load-bearing capacity.

[0042] More specifically, the container clamping position 110 horizontally penetrates the supporting square tubes 100 along the direction in which the plurality of supporting square tubes 100 are arranged in parallel.

[0043] like Figures 2 to 4 As shown, in this embodiment, it is exemplarily explained that the direction in which the plurality of supporting square tubes 100 are arranged in parallel is also the horizontal direction perpendicular to the extension direction of the supporting square tubes 100, and the container clamping position 110 penetrates the supporting square tubes 100 along this direction. When the catalyst packing needs to be replaced, the packing frame 200 can be horizontally taken out from the container clamping position 110; and after the catalyst packing is replaced, the packing frame 200 can be horizontally sent into the container clamping position 110.

[0044] It can be understood that, in this embodiment, by reasonably setting the shape of the container clamping position 110 on the supporting square tube 100 , the disassembly and assembly of the filling frame 200 on the supporting square tube 100 can be more convenient.

[0045] More specifically, the container clamping position 110 includes a first clamping position 111 arranged on the supporting square tube 100 close to the inner wall of the reaction tank 400 and a second clamping position 112 arranged on the supporting square tube 100 located in the middle position of the reaction tank 400. When the filling frame 200 is arranged in the first clamping position 111, the movement in the vertical direction is not restricted. When the filling frame 200 is arranged in the second clamping position 112, the movement in the vertical direction is restricted.

[0046] like Figures 2 to 4 As shown, in the present embodiment, it is exemplified that the container clamping position 110 is set to different shapes according to the position of the corresponding supporting square tube 100. When the supporting square tube 100 is close to the inner wall of the reaction tank 400, that is, the two supporting square tubes 100 located at the edge among the plurality of supporting square tubes 100, the container clamping position 110 on the supporting square tube 100 is set to the first clamping position 111; and when the supporting square tube 100 is located in the middle position of the reaction tank 400, that is, the supporting square tube 100 located in the middle position among the plurality of supporting square tubes 100, the container clamping position 110 on the supporting square tube 100 is set to the second clamping position 112. When the filling frame 200 is arranged in the first clamping position 111, the filling frame 200 and the supporting square tube 100 do not form a movement limit in the vertical direction, that is, the filling frame 200 can be vertically disassembled and assembled from the first clamping position 111; when the filling frame 200 is arranged in the second clamping position 112, the filling frame 200 and the supporting square tube 100 form a movement limit in the vertical direction, that is, the filling frame 200 cannot be vertically disassembled and assembled from the second clamping position 112.

[0047] It can be understood that this embodiment reasonably sets the shape of the container clamping position 110 on the supporting square tube 100 at different positions, so that the filling frame 200 can be disassembled and assembled in the vertical direction at a position close to the inner wall of the reaction tank 400 where the space is limited, which is more convenient; and in the middle position of the reaction tank 400 where the space is relatively less limited, the filling frame 200 can remain stable on the supporting square tube 100 and is not easy to shake.

[0048] More specifically, the first clamping position 111 is set to a rectangular shape, and the bottom of the filling frame 200 arranged in the first clamping position 111 corresponds to the shape of the first clamping position 111; the second clamping position 112 is set to a dovetail shape, and the bottom of the filling frame 200 arranged in the second clamping position 112 corresponds to the shape of the second clamping position 112.

[0049] like Figure 3 and Figure 4As shown, in this embodiment, it is exemplarily explained that the first clamping position 111 is set to a rectangle, which means that the longitudinal section of the first clamping position 111 is rectangular, and the filling frame 200 arranged in the first clamping position 111 can be set to a rectangular parallelepiped, and its bottom can just extend into the first clamping position 111. It is not difficult to see that along the vertical direction, the filling frame 200 arranged in the first clamping position 111 is not restricted in moving in the first clamping position 111. The second clamping position 112 can be set to a dovetail shape, that is, the longitudinal section of the second clamping position 112 can be an isosceles trapezoid, and the bottom of the second clamping position 112 is wider and the top is narrower. The bottom of the filling frame 200 arranged in the second clamping position 112 can also be set to a dovetail shape, and its top can be set to a rectangle. It is not difficult to see that along the vertical direction, the filling frame 200 arranged in the second clamping position 112 is restricted in moving in the second clamping position 112.

[0050] Of course, in some embodiments, the first clamping position 111 can also be set to an arc with an arc less than or equal to 180 degrees, an inverted triangle, or an inverted isosceles trapezoid; and the second clamping position 112 can also be set to an arc with an arc greater than 180 degrees, an inverted "T" shape or a "cross" shape, etc.

[0051] It is understandable that this embodiment can ensure that the vertical movement of the filling frame 200 arranged in the first clamping position 111 is not restricted, and ensure that the vertical movement of the filling frame 200 arranged in the second clamping position 112 is restricted by reasonably setting the shapes of the first clamping position 111 and the second clamping position 112.

[0052] Specifically, the supporting square tube 100 and the filling frame 200 are both made of stainless steel.

[0053] like Figures 2 to 4 As shown, in this embodiment, it is exemplified that the supporting square tube 100 and the filling frame 200 can be made of 316L stainless steel material, which has excellent corrosion resistance and can meet the use requirements of the ozone catalytic oxidation device in the present application for treating liquor wastewater.

[0054] More specifically, the filling frame 200 is made of a stainless steel plate, and a plurality of through holes 210 are provided on the stainless steel plate making the filling frame 200 .

[0055] like Figure 2 and Figure 5 As shown, in this embodiment, the packing frame 200 can be made of stainless steel plate according to its actual shape, that is, the packing frame 200 arranged in the first clamping position 111 and the second clamping position 112 can be welded with corresponding steel plates according to its actual shape, and the welding method can be full welding. When preparing the stainless steel plate, a plurality of perforations 210 can be evenly opened, and the perforations 210 are used for the later wastewater and ozone to pass through.

[0056] It can be understood that in this embodiment, the filling frame 200 is made of a stainless steel plate, which makes it easy to prepare the filling frame 200 into a desired shape, thereby facilitating the need to arrange the filling frame 200 on the supporting square tube 100 .

[0057] Specifically, the packing structure further includes a support frame 300 , which is disposed on a steel structure 410 in the reaction tank 400 . The steel structure 410 is exposed on the inner wall of the reaction tank 400 , and the supporting square tube 100 is connected to the steel structure 410 .

[0058] like Figure 1 and Figure 2 As shown, in this embodiment, the steel structure 410 in the reaction tank 400 can be a steel structure 410 in the reaction tank 400 that plays a supporting role, such as an angle steel support beam in the reaction tank 400, which is exposed on the inner wall of the reaction tank 400. The supporting square tube 100 can be arranged on the steel structure 410 through the support frame 300 to avoid direct connection with the inner side of the reaction tank 400. The support frame 300 can also be made of square tubes, and its structure can be reasonably set according to actual needs.

[0059] It can be understood that in this embodiment, the supporting square tube 100 is arranged on the steel structure 410 exposed on the inner wall of the reaction tank 400 through the support frame 300, which can avoid the anti-corrosion layer on the inner wall of the reaction tank 400 from being damaged, and further reduce the impact of arranging the filler structure in the reaction tank 400 on the structure of the reaction tank 400.

[0060] The implementation principle of a packing structure provided in Example 1 of the present application is:

[0061] During the specific implementation, the support frame 300 is first arranged on the steel structure 410 exposed inside and outside the reaction tank 400, and then the support square tube 100 is arranged on the support frame 300. At the same time, the first clamping position 111 or the second clamping position 112 is opened on the support square tube 100 according to the position of the support square tube 100 in the reaction tank 400. According to the arrangement requirements of the first clamping position 111 or the second clamping position 112, the packing frame 200 is prepared and formed using a stainless steel plate. Subsequently, the catalyst packing is arranged in the packing frame 200, and then the packing frame 200 is arranged in the first clamping position 111 and the second clamping position 112. When the catalyst packing in the packing frame 200 is hardened due to scaling, the packing frame 200 can be removed from the support square tube 100 to replace the catalyst packing in the packing frame 200.

[0062] The present application can realize the modular setting of the packing structure, which is beneficial to the uniformity of water and gas distribution. At the same time, since the specific surface area of ​​the packing structure in the present application is small, the catalyst packing in the packing frame 200 is not easy to be hardened. Even if the hardening phenomenon occurs, the present application can also conveniently maintain the packing structure to ensure the treatment effect of the ozone catalytic oxidation device on liquor wastewater.

However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent.
