Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wastewater treatment, specifically to a heterogeneous catalytic ozone reactor with a porous carrier fixing structure. Background Technology
[0002] Heterogeneous catalytic ozone oxidation technology can utilize catalysts to activate ozone and generate various reactive oxygen species such as hydroxyl radicals, making it one of the effective technologies for deep wastewater treatment.
[0003] However, during use, heterogeneous catalysts are mostly filled on porous supports. As the usage time increases, the catalyst at the pore openings will be lost after being impacted by water flow, and the height will decrease, which will prevent the catalyst from fully contacting wastewater and ozone. It is necessary to push the catalyst out of the pores. However, after the catalyst is pushed out of the pores, the catalyst is not supported inside, has poor stability, and is easy to break.
[0004] Therefore, those skilled in the art have provided heterogeneous catalytic ozone reactors with porous carrier immobilization structures to address the aforementioned problems. Utility Model Content
[0005] To address the aforementioned problems, this invention provides a heterogeneous catalytic ozone reactor with a porous carrier fixing structure.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a heterogeneous catalytic ozone reactor with a porous carrier fixing structure, comprising: a carrier; vertical holes uniformly arranged on opposite sides of the carrier; an insert post, one end of which is inserted into the vertical hole and slidably sealed, forming a catalyst filling area between the vertical hole and one end of the insert post, the other end of the insert post extending out of the carrier; two reinforcing bent rods symmetrically fixed to one end of the insert post, and the two reinforcing bent rods passing through the filling area; the reinforcing bent rods are alternately provided with a first arc-shaped portion and a second arc-shaped portion; a limiting rod located at the opening of the filling area of the vertical hole; wherein, when the limiting rod contacts the two first arc-shaped portions during the upward movement of the insert post, the two corresponding second arc-shaped portions below abut against the inner wall of the vertical hole at their respective positions.
[0007] Preferably, the cross-section of the vertical hole is set to a regular hexagon or a regular quadrilateral, and the two second arc-shaped portions are located at opposite corners of the vertical hole.
[0008] Preferably, in the initial state, the reinforcing bend is positioned in a figure-eight shape at the opening of the filling area, and the width between the two reinforcing bends increases uniformly from the inside to the outside.
[0009] Preferably, multiple limiting rods are arranged in parallel, and the gaps between the first arc-shaped portions located in the same row or column are all on the same plane as the limiting rods.
[0010] Preferably, the plurality of inserts are arranged in parallel, and the plurality of inserts are respectively arranged coaxially with the plurality of vertical holes.
[0011] In summary, this utility model has the following beneficial technical effects: When the limiting rod contacts the two first arc-shaped parts during the upward movement of the insertion column, the two corresponding second arc-shaped parts below abut against the inner wall of the vertical hole at their relative positions, which can form a stable force balance. The first arc-shaped parts are closest in the horizontal direction, and the channel through which the limiting rod passes is the narrowest. The second arc-shaped parts contact and support the vertical hole, which can effectively limit the uneven deformation and breakage of the catalyst in the filling area under lateral force, improve the stability of the catalyst during the support process, and reduce the consumption caused by impact.

[0018] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0019] Heterogeneous catalytic ozone reactor with porous support structure, reference Figure 1-4It includes: a carrier 1, which can be set as a cuboid. The regular shape can ensure that the distance between adjacent components is uniform, so that the wastewater is more evenly distributed during the flow process, avoiding the difference in catalytic efficiency caused by local water accumulation or excessive flow rate, and significantly improving the space utilization and operational stability of the overall reaction device.
[0020] Vertical holes 11 are evenly distributed on opposite sides of the carrier 1.
[0021] The insert 2 has one end slidably inserted into the vertical hole 11. This end fits against the inner side of the vertical hole 11 to form a seal, or the end is wrapped with an elastic gasket to achieve a seal, or other methods that can achieve a seal. The vertical hole 11 and one end of the insert 2 form a catalyst filling area. The other end of the insert 2 extends out of the carrier 1 and can be used for overall support to achieve automatic adjustment of the filling area height.
[0022] Two reinforcing bent rods 21 are symmetrically fixed to one end of the insert 2, and the two reinforcing bent rods 21 pass through the filling area. The symmetrical fixed structure can ensure that the supporting force of the reinforcing bent rods 21 on the filling area is evenly distributed, avoiding uneven local pressure on the catalyst due to unilateral force. The design of the reinforcing bent rods 21 passing through the filling area can directly contact the catalyst and form a "skeleton" support, which enhances the structural strength of the catalyst from the inside and prevents the catalyst from collapsing as a whole under the impact of water flow or vibration.
[0023] After the catalyst is filled in the filling area, it can solidify automatically. The reinforcing rod 21 can improve the stability of the catalyst and prevent it from easily breaking. The automatically solidified catalyst can be tightly combined with the reinforcing rod 21, further strengthening the integrated structure of the "skeleton-catalyst", reducing the gap between the catalyst and the reinforcing rod 21, and reducing the scouring loss of the catalyst by the water flow.
[0024] The reinforcing bent rod 21 is staggered with a first arc-shaped part 211 and a second arc-shaped part 212. Compared with a straight rod, the arc-shaped structure can distribute stress more evenly. When the catalyst is impacted, the arc-shaped part can transmit the impact force to all directions instead of concentrating it at a certain point. At the same time, the staggered first arc-shaped part 211 and the second arc-shaped part 212 can form multi-dimensional support nodes in the filling area, which can further improve the stability of the catalyst, especially resist the irregular impact force generated during the flow of wastewater and reduce the probability of catalyst breakage.
[0025] The limiting rod 3 is located at the filling area opening of the vertical hole 11. It can be placed vertically and supported by the insert post 2. The vertically placed limiting rod 3 can be accurately aligned with the filling area opening to ensure accurate blocking position of the catalyst. The design of being supported by the insert post 2 allows the limiting rod 3 and the insert post 2 to form a linkage, avoiding loosening or misalignment of the limiting rod 3 due to independent fixing.
[0026] The limiting rod 3 can block the catalyst at the opening of the filling area. When the catalyst at the opening of the filling area is reduced by the impact, the insert 2, the reinforcing bent rod 21 and the catalyst will rise as a whole and abut against the limiting rod 3. The height of the filling area will decrease, so that the amount of catalyst exposed at the opening of the filling area remains unchanged, thereby ensuring the catalytic effect.
[0027] The pressure of the carrier 1 ensures that the catalyst is always located at the inlet of the filling zone. The inlet position allows the catalyst to preferentially contact the incoming wastewater and ozone, shortening the reaction path and increasing the rate of the catalytic reaction. At the same time, it avoids local idleness caused by excessive settling of the catalyst, maximizing the utilization of the active sites of the catalyst.
[0028] During the upward movement of the insertion post 2, when the limiting rod 3 contacts the two first arc-shaped parts 211, the two corresponding second arc-shaped parts 212 below abut against the inner wall of the vertical hole 11 at their respective positions. This "two-way support" structure can form a stable force balance. The contact between the first arc-shaped part 211 and the limiting rod 3 restricts the upward displacement, while the contact between the second arc-shaped part 212 and the inner wall of the vertical hole 11 restricts the downward offset, effectively preventing the insertion post 2 from tilting or getting stuck during movement and ensuring the smooth operation of the component.
[0029] The first arc-shaped part 211 is the closest in the horizontal direction, and the channel through which the limiting rod 3 passes is the narrowest. When passing through this point, the second arc-shaped part 212 contacts and supports the vertical hole 11, which can effectively limit the uneven deformation and breakage of the catalyst in the filling area under lateral force, improve the stability of the catalyst during the support process, and reduce the consumption caused by impact.
[0030] The cross-section of the vertical hole 11 is set as a regular hexagon or a regular quadrilateral. The two second arc-shaped parts 212 are located at opposite corners of the vertical hole 11, which allows the two reinforcing bent rods 21 to be kept on the same vertical plane. The polygonal structure can form a closer contact with the second arc-shaped parts 212, ensuring the effective transmission of support force, limiting misalignment, and further improving stability during use.
[0031] When the insert 2 is in its initial state, the opening of the reinforcing bend 21 in the filling area is set in a figure-eight shape, and the width between the two reinforcing bends 21 increases uniformly from the inside to the outside, which can quickly cooperate with the limiting rod 3 and facilitate installation.
[0032] Multiple limiting rods 3 are arranged in parallel, and the gaps between the first arc-shaped portions 211 located in the same row or column are all on the same plane as the limiting rods 3. Multiple sets of reinforcing bent rods 21 can be limited by one limiting rod 3. This significantly reduces the number of limiting rods 3 used, reducing the manufacturing cost and structural complexity of the component. At the same time, the arrangement on the same plane ensures uniform limiting force and prevents some reinforcing bent rods 21 from shifting due to incomplete limiting.
[0033] Multiple insertion posts 2 are arranged in parallel, and each insertion post 2 is coaxially arranged with multiple vertical holes 11. The parallel and coaxial design ensures that the force direction and displacement path of each insertion post 2 are consistent, providing stable multi-point support for the whole and preventing easy tilting. This ensures that the component can maintain structural flatness when subjected to wastewater pressure or vibration.
[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
