Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment, and in particular relates to a continuous flow reaction device for Fenton catalyst. Background Technology

[0002] In the field of wastewater treatment, Fenton catalytic oxidation is a commonly used and technologically mature oxidation method. The Fenton method can be applied to wastewater pretreatment to improve its biodegradability and reduce biotoxicity, as well as to upgrade wastewater discharged from enterprises and sewage treatment plants for advanced treatment. In specific wastewater treatment implementation, the Fenton catalyst is placed in a continuous flow reactor. Wastewater is pumped into one end of the reactor and discharged from the other end after the Fenton reaction. The Fenton catalyst needs to be evenly distributed inside the reactor. During treatment, the wastewater continuously flows over the catalyst, and the impact of the water flow can cause the catalyst to be dispersed, resulting in uneven distribution. Uneven distribution can prevent the wastewater from fully reacting, reducing the purification effect. Utility Model Content

[0003] In order to solve the problems in the related technology, this utility model provides a continuous flow reaction device for Fenton catalyst that can level the Fenton catalyst when treating wastewater.

[0004] The technical solution is as follows:

[0005] A continuous flow reaction apparatus for Fenton catalyst includes a reaction tube, a flat plate, a first magnetic block, a second magnetic block, a water-permeable partition, an inlet, and an outlet. The flat plate has an edge with a mounting groove. The inlet is connected to the inlet end of the reaction tube, and the outlet is connected to the outlet end of the reaction tube. The water-permeable partition is located inside the reaction tube, between the inlet and outlet ends. The flat plate is positioned above the water-permeable partition, and its periphery is attached to the inner wall of the reaction tube. The first magnetic block is disposed within the mounting groove, with one side attached to the inner wall of the reaction tube. The second magnetic block is disposed on the outer wall of the reaction tube, corresponding to the first magnetic block. The magnetic poles of the second magnetic block and the first magnetic block are opposite on opposite sides. The water-permeable partition is configured to hold the catalyst.

[0006] The beneficial effect of this technical solution is that by moving the second magnetic block on the outer wall of the reaction tube, the first magnetic block is magnetically controlled, and the first magnetic block and the flat plate follow the movement of the second magnetic block, thereby realizing the external control of the flat plate inside the reaction tube, and thus flattening the catalyst on the water-permeable partition.

[0007] Furthermore, it also includes a first limiting slide rail, which is disposed on the outer wall of the reaction tube along the height direction, and the second magnetic block is slidably connected to the first limiting slide rail.

[0008] Furthermore, it also includes a second limiting slide rail, which is disposed on the inner wall of the reaction tube along the height direction; the edge of the flat plate is provided with a slide rail groove, and the flat plate is slidably connected to the second limiting slide rail through the slide rail groove.

[0009] Furthermore, it also includes a limiting ring, which is disposed between the flat plate and the permeable partition, and the limiting ring is configured to limit the flat plate in the height direction.

[0010] Furthermore, the second magnetic block is provided with a handle.

[0011] Furthermore, the flat plate has permeable grooves. Attached Figure Description

[0023] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0024] Fenton catalysts need to be laid flat inside a continuous flow reactor. During treatment, wastewater continuously flows over the Fenton catalyst, and the impact of the water flow can cause the catalyst to be dispersed, resulting in uneven placement. Uneven placement can prevent the wastewater from reacting fully, reducing the purification effect. To solve the above technical problems, this invention provides a continuous flow reactor for Fenton catalysts that can level the Fenton catalyst during wastewater treatment.

[0025] like Figure 1-2 As shown:

[0026] This invention provides a continuous flow reaction apparatus for Fenton catalysts, comprising a reaction tube 1, a flat plate 2, a first magnetic block 21, a second magnetic block 22, a water-permeable partition 3, an inlet 11, and an outlet 12. The flat plate 2 has an edge with a mounting groove. The inlet 11 is connected to the inlet end of the reaction tube 1, and the outlet 12 is connected to the outlet end of the reaction tube 1. The water-permeable partition 3 is located inside the reaction tube 1, between the inlet and outlet ends. Plate 2 is positioned above the permeable partition 3, with its periphery attached to the inner wall of the reaction tube 1; the first magnetic block 21 is positioned in the mounting groove, with one side of the first magnetic block 21 attached to the inner wall of the reaction tube 1; the second magnetic block 22 is positioned on the outer wall of the reaction tube 1, corresponding to the first magnetic block 21; the magnetic poles of the second magnetic block 22 and the first magnetic block 21 are opposite on their opposing sides; the permeable partition 3 is configured to hold the catalyst.

[0027] The wastewater to be treated is pumped into the bottom of the reaction tube 1 through the inlet 11 by a water pump. As it moves upward, it flows over the catalyst on the permeable partition 3 and reacts. Finally, it flows out from the outlet 12 into the subsequent treatment equipment. Since the reaction inside the reaction tube 1 is constantly reacting as the wastewater flows through, it is not convenient to open the reaction tube 1 to level the catalyst when it is unevenly placed. Therefore, it is necessary to control the first magnetic block 21 inside the reaction tube 1 through the wall of the external second magnetic block 22. Since the magnetic poles of the second magnetic block 22 and the first magnetic block 21 are opposite on opposite sides, a magnetic attraction is generated between the second magnetic block 22 and the first magnetic block 21. When the second magnetic block 22 moves downward, the first magnetic block 21 also moves downward. Then, by connecting the leveling plate 2 to the first magnetic block 21, the leveling plate 2 can be controlled to move up and down. The downward movement of the leveling plate 2 can press down on the catalyst on the permeable partition 3, making the catalyst level. This technical solution allows for catalyst leveling without opening the reaction tube 1 during the reaction process, thus ensuring both the reaction rate and improving wastewater purification. By moving the second magnetic block 22 along the outer wall of the reaction tube 1, the first magnetic block 21 is magnetically controlled, causing the first magnetic block 21 and the leveling plate 2 to move along with the second magnetic block 22. This achieves external control of the leveling plate 2 inside the reaction tube 1, thereby leveling the catalyst on the permeable partition 3.

[0028] In an optional embodiment, a first limiting slide rail 4 is further included. The first limiting slide rail 4 is disposed on the outer wall of the reaction tube 1 along the height direction, and the second magnetic block 22 is slidably connected to the first limiting slide rail 4. The first limiting slide rail 4 can assist the user in moving the second magnetic block 22 up and down, and prevent the second magnetic block 22 from deviating, which would cause a decrease in the magnetic attraction between it and the first magnetic block 21.

[0029] In an optional embodiment, a second limiting slide rail 5 is further included, which is disposed on the inner wall of the reaction tube 1 along the height direction; the edge of the flat plate 2 is provided with a slide rail groove, and the flat plate 2 is slidably connected to the second limiting slide rail 5 through the slide rail groove. Multiple second limiting slide rails 5 can be provided on the inner wall of the reaction tube 1, and the second limiting slide rails 5 can keep the flat plate 2 stable during the up and down movement of the flat plate 2, thereby improving the flatness effect on the catalyst.

[0030] In an optional embodiment, a limiting ring 6 is further included, disposed between the flat plate 2 and the permeable partition 3. The limiting ring 6 is configured to limit the height of the flat plate 2. The limiting ring 6 is used to restrict the maximum downward movement distance of the flat plate 2, preventing the flat plate 2 from pressing the catalyst too much, which would cause the catalyst to be compacted, reducing the contact area with the wastewater and decreasing the reaction rate.

[0031] In one alternative embodiment, the second magnetic block 22 is provided with a handle 7. The handle 7 makes it easier for an operator to hold and move the second magnetic block 22.

[0032] In an optional embodiment, the flat plate 2 has permeable grooves 23. The permeable grooves 23 are used for wastewater to pass through, and the width of the permeable grooves 23 should be smaller than the average size of the catalyst particles.
