[0030] Such as Figure 1 And Figure 2As shown in the figure, the present application provides a reaction device. The first embodiment of the reaction device of the present application includes: a reaction matrix 10, a feeding structure 20, an overflow assembly 30, and a cloth distribution structure 40; the reaction matrix 10 has a reaction chamber 11; the feeding structure 20 is arranged at the upper end of the reaction matrix 10 and communicates with the reaction chamber 11 to input a liquid material into the reaction chamber 11; the overflow assembly 30 is arranged in the reaction chamber 11 and is located below the feeding structure 20. The overflow assembly 30 includes a first overflow structure 31. After the liquid material flows through the first overflow structure 31, it is distributed. The first overflow structure 31 has a first overflow end 311; the cloth distribution structure 40 is arranged in the reaction chamber 11 to input a fluid material into the reaction chamber 11. The cloth distribution structure 40 includes a first cloth distribution member 41. The first cloth distribution member 41 is located below the first overflow structure 31 and at the first overflow end 311. The fluid material is mixed with the first material through the first cloth distribution member 41.

[0031] Applying the technical solution of this embodiment, the reaction matrix 10 has a reaction chamber 11. The reaction matrix 10 provides an installation basis for each component of the reaction device. The reaction chamber 11 provides a space for mixing and reacting the liquid material and the fluid material. The feeding structure 20 is arranged at the upper end of the reaction matrix 10 and communicates with the reaction chamber 11 to input the liquid material into the reaction chamber 11. The liquid material flows downward under the action of its own gravity. The overflow assembly 30 is arranged in the reaction chamber 11 and is located below the feeding structure 20. The overflow assembly 30 includes a first overflow structure 31. After the liquid material flows through the first overflow structure 31, it is distributed. The first overflow structure 31 has a first overflow end 311. The liquid material can be distributed at the first overflow end 311 and then flow downward; the cloth distribution structure 40 is arranged in the reaction chamber 11 to input the fluid material into the reaction chamber 11. The cloth distribution structure 40 includes a first cloth distribution member 41. The first cloth distribution member 41 is located below the first overflow structure 31 and at the first overflow end 311. The first cloth distribution member 41 can distribute the fluid material. Since the liquid material can be distributed at the first overflow end 311 and the fluid material can also be distributed at the first overflow end 311, the liquid material and the fluid material can be fully mixed at the first overflow end 311, thereby ensuring that the reaction between the liquid material and the fluid material can proceed more thoroughly. Therefore, the technical solution of this embodiment can effectively solve the problem of incomplete reaction in the related art.

[0032] It should be noted that in this embodiment, the reaction device is a device for treating the finished liquid. Specifically, it is to remove the TOC in the finished liquid. The finished liquid can be the nickel sulfate, cobalt, and manganese finished liquid at the end of the production line in the hydrometallurgy industry. It has the characteristics that the components of TOC are complex and difficult to degrade, seriously affecting the morphology and quality of nickel sulfate, cobalt, and manganese crystals. The feed liquid in this embodiment is a mixture of the finished liquid and a liquid-phase catalyst, where the liquid-phase catalyst is hydrogen peroxide. Pre-mixing the finished liquid and the liquid-phase catalyst outside the reaction device is beneficial to the subsequent reaction. The fluid material in this embodiment is a gaseous oxidant, that is, ozone. Ozone has strong oxidizing properties. Using ozone to treat the finished liquid will not pose a risk of secondary pollution to the treated liquid, which is a relatively safe treatment technology. However, ozone also has the characteristics of low solubility in water and easy decomposition. In addition, in other embodiments, the fluid material can also be a liquid-phase substance. "The feed liquid is distributed after flowing through the first overflow structure 31" means that compared with the scheme of forming a bundle of fluid when the feed liquid is input using a feed pipe, the feed liquid in this embodiment will be dispersed at the first overflow end 311 after flowing through the first overflow structure 31, so as to achieve the effect of increasing the contact area for subsequent contact with the fluid material, and further making the mixing of the feed liquid and the fluid material more uniform, and thus making its reaction more sufficient and thorough.

[0033] As Figure 1 and Figure 2 shown, the overflow assembly 30 further includes a second overflow structure 32 disposed below the first cloth member 41. The second overflow structure 32 has a second overflow end 321. The cloth structure 40 further includes a second cloth member 42. The second cloth member 42 is located below the second overflow structure 32 and at the second overflow end 321. The feed liquid is distributed after flowing through the second overflow structure 32. Specifically, the setting of the second overflow structure 32 enables the feed liquid to be distributed in multiple stages through the first overflow structure 31 and the second overflow structure 32. The second cloth member 42 is disposed at the second overflow end 321, enabling the feed liquid to be mixed with the fluid material at each stage of distribution, thereby further making the mixing of the feed liquid and the fluid material more uniform, and thus making its reaction more sufficient and thorough.

[0034] As Figure 1 and Figure 2As shown, the first overflow structure 31 includes a horizontal plate body 312 connected to the inner surface of the reaction matrix 10 and a vertical plate body 313 connected to the horizontal plate body 312. The projection of the vertical plate body 313 on the horizontal plane is within the range of the second overflow structure 32. Specifically, a receiving groove is formed between the horizontal plate body 312, the vertical plate body 313 and the inner surface of the reaction matrix 10 to receive the liquid material. When the liquid material in the receiving groove can be stored to a certain volume, the liquid material will overflow the receiving groove after passing over the vertical plate body 313. Therefore, the first overflow end 311 is also the position where the vertical plate body 313 is located. After the liquid material passes over the vertical plate body 313, it will form a waterfall-like flow state. Compared with the bundle-like fluid formed in the related art, the waterfall-like fluid can have a larger contact area with the fluid material. The second overflow structure 32 also has a structure similar to that of the first overflow structure 31, which will not be elaborated here. The projection of the vertical plate body 313 on the horizontal plane is within the range of the second overflow structure 32, so that the liquid material can reach the second overflow structure 32 after overflowing from the first overflow structure 31, rather than overflowing to other positions in the reaction chamber 11.

[0035] As Figure 1 and Figure 2 shown, the reaction matrix 10 includes a first side plate 12 and a second side plate 13 arranged oppositely. The first overflow structure 31 is connected to the first side plate 12, and the second overflow structure 32 is connected to the second side plate 13. Specifically, such an arrangement makes both the first overflow end 311 and the second overflow end 321 close to the middle position of the reaction chamber 11, thereby making the installation positions of the first cloth member 41 and the second cloth member 42 more reasonable. In this embodiment, both the first overflow structure 31 and the second overflow structure 32 are multiple, and the multiple first overflow structures 31 and the multiple second overflow structures 32 are arranged alternately, so that the flow path of the liquid material in the reaction chamber 11 is long enough. Each first overflow structure 31 is provided with a corresponding first cloth member 41, and each second overflow structure 32 is provided with a corresponding second cloth member 42.

[0036] As Figure 1 and Figure 2 shown, the cloth structure 40 further includes a third cloth member 43 located above the second overflow structure 32. The third cloth member 43 distributes the material downward, and the first cloth member 41 distributes the material upward. Specifically, the first cloth member 41 distributes the material upward, and the liquid material flows downward after overflowing from the first overflow end 311. The moving directions of the fluid material and the liquid material are roughly opposite, so that the fluid material and the liquid material are more likely to be mixed. Part of the liquid material will accumulate at the second overflow structure 32 after overflowing from the first overflow end 311. The third cloth member 43 is located above the second overflow structure 32 and the third cloth member 43 distributes the material downward, so that the fluid material distributed by the third cloth member 43 can be mixed and reacted with the liquid material in the second overflow structure 32.

[0037] As Figure 1and Figure 2 As shown in Figure 2 , the first overflow structure 31 is provided with a through hole. The cloth structure 40 further includes a fourth cloth member 44 located below the first overflow structure 31, and the projection of the fourth cloth member 44 on the horizontal plane is within the range of the first overflow structure 31. Specifically, a part of the liquid material in the first overflow structure 31 can flow directly downward through the through hole. The through hole is disposed through the horizontal plate body 312. The fourth cloth member 44 can distribute the fluid material so that the fluid material can be mixed with the liquid material passing through the through hole. It should be noted that the amount of the liquid material flowing through the through hole is less than the amount of the liquid material flowing through the vertical plate body 313.

[0038] As Figure 1 and Figure 2 As shown in Figure 2 , the cloth structure 40 includes a base pipe 45, a main body pipe 46, and a side pipe 47. The base pipe 45 is used to introduce the fluid material. The base pipe 45 is located at the lower end of the reaction chamber 11. The main body pipe 46 extends in the vertical direction and is connected to the base pipe 45. The side pipe 47 is connected to the main body pipe 46, and the first cloth member 41 is connected to the side pipe 47. Specifically, in this embodiment, the base pipe 45 includes an annular pipe and a connecting pipe. Both ends of the connecting pipe are connected to the annular pipe. The connecting pipe is located in the middle of the lower end of the reaction chamber 11, and the main body pipe 46 is connected to the middle of the connecting pipe, so that the main body pipe 46 is generally located in the middle position of the reaction chamber 11. There are multiple side pipes 47. The first cloth member 41, the second cloth member 42, the third cloth member 43, and the fourth cloth member 44 are all connected to the respective side pipes 47. The multiple side pipes can be arranged at intervals along the axial direction of the main body pipe 46 or at intervals along the circumferential direction of the main body pipe 46, so as to play a role in adjusting the positions of the respective cloth members.

[0039] It should be noted that, as Figure 2 shown in Figure 2 , the dotted lines and the hollow arrows show the moving direction of the liquid material, and the dotted lines and the solid arrows show the moving direction of the flowing material. In other embodiments, the form of the connecting components of the cloth structure is not limited. That is to say, it is not necessary to include the main body pipe and the side pipe. As long as certain connecting components are provided to make each cloth member located in a suitable position, for example, each cloth member is provided with a separate connecting pipe to connect the cloth member and the structure for storing the fluid material, and the above effects can also be achieved. However, the cloth structure 40 arranged as in the first embodiment can use fewer connecting components, making the layout of the cloth structure 40 more reasonable.

[0040] As Figure 1As shown, the fabric structure 40 further includes a fabric tube 48 located at the lower end of the reaction chamber 11. The fabric tube 48 communicates with the base tube 45. The fabric structure 40 further includes a plurality of fifth fabric members 49 communicating with the fabric tube 48. Specifically, the fabric tube 48 includes a plurality of straight tubes arranged vertically and horizontally, and the plurality of straight tubes are all communicated with the annular tube. The plurality of fifth fabric members 49 are arranged in an array on the straight tubes, and the fifth fabric members 49 can distribute the fluid material from the lower end of the reaction chamber 11.

[0041] As Figure 1 shown, the reaction device further includes a reflux structure 50. The inlet of the reflux structure 50 is arranged at the upper end of the reaction matrix 10 and communicates with the reaction chamber 11, and the outlet of the reflux structure 50 communicates with the fabric structure 40. Specifically, the setting of the reflux structure 50 enables the unreacted ozone to be recovered and reused after moving to the upper end of the reaction chamber 11.

[0042] As Figure 1 shown, the reaction device further includes an absorption structure 60. The inlet of the absorption structure 60 is arranged at the upper end of the reaction matrix 10 and communicates with the reaction chamber 11 to absorb the fluid material. Specifically, the absorption structure 60 includes an activated carbon column, and the activated carbon column can absorb the unreacted ozone to prevent potential harm to the environment caused by ozone.

[0043] In addition, in this embodiment, the height of the vertical plate body 313 is between 10 cm and 20 cm so that the first overflow end 311 can hold an appropriate amount of the liquid material. The reaction matrix 10 is made of plexiglass, and the thickness of the reaction matrix 10 is between 2 cm and 5 cm so that the reaction matrix 10 can play a heat preservation effect on the material in the reaction chamber 11.

[0044] The following is a display of the effect of removing TOC from the finished liquid using the reaction device of this embodiment under different conditions:

[0045] The first example: The finished liquid is the liquid after degreasing nickel sulfate, the TOC content is 221.8 mg / L, the temperature is 50 °C, the pH value is 4.5, and the flow rate is 400 mL / min; the liquid-phase catalyst is hydrogen peroxide, the dosage is 0.3%, and the flow rate is 1 mL / min; the gas-phase oxidant is ozone, and the ozone outlet flow rate is 20 L / min; the reaction duration is 120 min.

[0046] The TOC content and removal rate after the first example treatment are as follows:

[0047]

[0048] Second example: The finished product liquid is the liquid after degreasing cobalt sulfate, with a TOC content of 180.3 mg / L, a temperature of 50 °C, a pH value of 4.3, and a flow rate of 450 mL / min; the liquid-phase catalyst is hydrogen peroxide, with a dosage of 0.2% and a flow rate of 0.5 mL / min; the gas-phase oxidant is ozone, with an ozone outlet flow rate of 10 L / min; the reaction duration is 120 min.

[0049] The TOC content and removal rate after treatment in the second example are as follows:

[0050]

[0051] Third example: The finished product liquid is the liquid after degreasing cobalt sulfate, with a TOC content of 200.1 mg / L, a temperature of 50 °C, a pH value of 4.5, and a flow rate of 420 mL / min; the liquid-phase catalyst is hydrogen peroxide, with a dosage of 0.2% and a flow rate of 0.8 mL / min; the gas-phase oxidant is ozone, with an ozone outlet flow rate of 15 L / min; the reaction duration is 120 min.

[0052] The TOC content and removal rate after treatment in the third example are as follows:

[0053]

[0054] As Figure 3 shown, the second embodiment of the reaction device provided by the present application is different from the first embodiment in that the setting method of the overflow structure is different. In this embodiment, the overflow structures are stacked, and each overflow structure includes a horizontal plate body and a vertical plate body. In two adjacent overflow structures, the horizontal plate body of the upper overflow structure is completely within the range of the horizontal plate body of the lower overflow structure, and the vertical plate bodies are all located on the same side of the corresponding horizontal plate body. With such a setting, the above effects can also be achieved.

[0055] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0056] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations of the spatial relative descriptions used herein will be made accordingly.

[0057] In addition, it should be noted that the use of terms such as "first" and "second" to define components is only for the convenience of distinguishing the corresponding components. Without additional statements, these terms have no special meanings, and thus should not be construed as limiting the protection scope of the present utility model.

[0058] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
