[0003] Electrochemical oxidation technology is regarded as one of the most effective wastewater treatment technologies in the 21st century because it produces no toxic or harmful substances during the degradation of pollutants and can convert toxic and harmful substances into non-toxic and harmless products. However, the degradation effect of existing equipment using electrocatalytic oxidation technology to treat wastewater is poor. Utility Model Content

[0010] Wherein, the sub-flow channels of two adjacent degradation sections communicate with each other; in the degradation section close to the liquid inlet, the liquid inlet end of the sub-flow channel communicates with the liquid inlet; in the degradation section close to the liquid outlet, the liquid outlet end of the sub-flow channel communicates with the liquid outlet.
[0011] Further, the electrode includes a first electrode and a second electrode. Each group of the first electrodes and any one group of the second electrodes are arranged in a corresponding degradation section; in the same degradation section, a plurality of the first electrodes and a plurality of the second electrodes are respectively arranged on the opposite inner walls of the degradation section and are alternately arranged at intervals along the extending direction of the flow channel.
[0012] Furthermore, the flow channel further comprises a plurality of connecting sections, each of which is located between two adjacent degradation sections along the extending direction of the flow channel and is connected to the sub-flow channels of the two adjacent degradation sections.
[0013] Furthermore, the shell is provided with a plurality of sampling ports, and each of the sampling ports is connected to a corresponding one of the connecting sections.
[0014] Furthermore, the plurality of partitions include a plurality of first partitions and a plurality of second partitions, and the plurality of first partitions and the plurality of second partitions are respectively arranged on the inner walls on both sides opposite to each other in the width direction of the inner cavity, and are alternately arranged along the length direction of the inner cavity to form the flow channel in the inner cavity.
[0015] Furthermore, the plurality of partitions further include a third partition and a fourth partition, the third partition and the fourth partition are respectively arranged on two inner walls opposite to each other in the length direction of the inner cavity, and the third partition and the fourth partition respectively constitute the side walls of the two degradation sections.
[0016] Furthermore, the shell includes a shell and a cover, the shell is provided with a cavity with an opening, the cover is detachably connected to the shell, and when connected to the shell, closes the opening to enclose the shell and form the inner cavity.
[0017] Furthermore, the shell is provided with the liquid inlet and the liquid outlet, and the liquid inlet and the liquid outlet are located on a side of the shell away from the cover body and at two ends of the shell in the length direction.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present application.
[0028] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.
[0029] The present application provides a degradation device for treating wastewater, and the degradation effect of the degradation device is good, which can solve the problem that the degradation effect of the existing device for treating wastewater by electrocatalytic oxidation technology is relatively poor.
[0030] As Figure 1 and Figure 2 shown, the degradation device 100 includes a housing 110 and multiple partition plates 120. The housing 110 is provided with an inner cavity 111, a liquid inlet 112 and a liquid outlet 113 communicating with the inner cavity 111. The multiple partition plates 120 are arranged at intervals in the inner cavity 111 to form a tortuously extending flow channel in the inner cavity 111. The two ends of the flow channel are respectively communicated with the liquid inlet 112 and the liquid outlet 113, and the flow channel includes a plurality of degradation segments 131 arranged in sequence along its own extending direction.
[0031] Furthermore, the degradation device 100 further includes multiple groups of electrodes. Each group of electrodes is arranged in a corresponding degradation segment 131. And in any degradation segment 131, the multiple electrodes of each group are arranged at intervals, and some electrodes are arranged on the partition plate 120 to form a tortuously extending sub-flow channel 132 in the degradation segment.
[0032] Among them, the sub-flow channels 132 of two adjacent degradation segments 131 are communicated with each other; in the degradation segment 131 close to the liquid inlet 112, the liquid inlet end of the sub-flow channel 132 is communicated with the liquid inlet 112; in the degradation segment 131 close to the liquid outlet 113, the liquid outlet end of the sub-flow channel 132 is communicated with the liquid outlet 113.
[0033] It can be determined that the electrodes are used to electrolyze the wastewater flowing into the inner cavity 111, so the electrodes include a positive electrode and a negative electrode. Specifically in the Figure 1 shown embodiment, the electrodes are in a plate shape.
[0034] Using the above-mentioned degradation device 100, the wastewater flows into the inner cavity 111 through the liquid inlet 112, and then the wastewater flows along the flow channel. When passing through the degradation segment 131, the wastewater flows along the sub-flow channel 132 of the degradation segment 131, and under the electrolytic oxidation of the electrodes, the organic matter in the wastewater is degraded. Since the flow channel is tortuously extending, and tortuously extending sub-flow channels 132 are formed in multiple degradation segments 131 of the flow channel, the residence time of the wastewater in the inner cavity 111 can be prolonged. At the same time, the wastewater will present a turbulent state when flowing in the sub-flow channel 132, improving the mixing effect of the wastewater, so as to effectively improve the electrolytic oxidation effect and achieve a better degradation effect.
[0035] In addition, the degradation device 100 provided by the present application has a simple structure, and the degradation can be completed during the continuous flow of the wastewater in the inner cavity 111, with high working efficiency.
[0036] It should be explained that the process of electrolytic oxidation of wastewater is a continuous process. In this process, part of the wastewater is first treated, and the treated wastewater will be mixed with the untreated wastewater and then continue to be electrolytically oxidized. If the mixing effect is poor, it will affect the subsequent electrolytic oxidation effect. Therefore, the above-mentioned setting of the sub-flow channel 132 improves the mixing effect of the wastewater, and further improves the electrolytic oxidation effect.
[0037] In one embodiment, the housing 110 includes a shell 114 and a cover 115. The shell 114 is provided with a cavity having an opening. The cover 115 is detachably connected to the shell 114 and closes the opening when connected to the shell 114, so as to enclose the shell 114 to form the inner cavity 111. In this way, the cover 115 can be detached when it is necessary to clean or replace the components in the inner cavity 111, so as to facilitate the maintenance of the degradation device 100.
[0038] Furthermore, the shell 114 is provided with a liquid inlet 112 and a liquid outlet 113, which are located on the side of the shell 114 away from the cover 115 and are respectively located at both ends of the length direction of the shell 114. In this way, the mechanism connected to the liquid inlet 112 and the mechanism connected to the liquid outlet 113 can be arranged on the same side of the shell 110, which is convenient for the arrangement and access of other mechanisms. Of course, the positions of the liquid inlet 112 and the liquid outlet 113 can also be opened according to actual conditions, which will not be described in detail here.
[0039] Specific to Figure 1 In the embodiment shown, the housing 110 is a rectangular parallelepiped, the liquid inlet 112 and the liquid outlet 113 are located at both ends of the length direction of the housing 110, and the flow channel formed in the inner cavity 111 extends in a zigzag manner along the length direction of the housing 110. It can be understood that the length direction of the inner cavity 111 is the same as the length direction of the housing 114, that is, the length direction of the housing 110. Figure 1 The left and right direction in .
[0040] In one embodiment, the plurality of baffles 120 include a plurality of first baffles 121 and a plurality of second baffles 122, and the plurality of first baffles 121 and the plurality of second baffles 122 are respectively disposed on the inner walls of the inner cavity 111 on both sides opposite to each other in the width direction. Figure 1 A plurality of first baffles 121 and a plurality of second baffles 122 are arranged alternately along the length direction of the inner cavity 111, that is, along Figure 1 The inner cavity 111 is arranged alternately in the left and right directions to form the above-mentioned zigzag extending flow channel in the inner cavity 111. Similarly, it can be known that the width direction of the inner cavity 111 is the width direction of the outer shell 110, that is, Figure 1 The up and down directions in .
[0041] It can be understood that, in order to form the above-mentioned flow channel, the first partition plate 121 and the second partition plate 122 are spaced apart from the inner wall on the opposite side, that is, Figure 1 There is a gap between the first partition 121 and the upper inner wall (the cover 115 ) and there is a gap between the second partition 122 and the lower inner wall. Similarly, in the degradation section 131 , there is also a gap between the electrode and the inner wall on the opposite side.
[0042] Further, the multiple partition plates 120 further include a third partition plate 123 and a fourth partition plate 124. The third partition plate 123 and the fourth partition plate 124 are respectively disposed on the opposite inner walls of the inner cavity 111 in the length direction, and the third partition plate 123 and the fourth partition plate 124 respectively form the side walls of the two degradation sections 131.
[0043] It can be understood that for the degradation section 131 located in the middle of the flow channel along the extension direction of the flow channel, the two side walls of the degradation section 131 are usually formed by the first partition plate 121 and the second partition plate 122. For the two degradation sections 131 at both ends of the flow channel, the two side walls of one degradation section 131 are formed by any one of the first partition plate 121 and the second partition plate 122 and one of the third partition plate 123 and the fourth partition plate 124, and the two side walls of the other degradation section 131 are formed by any one of the first partition plate 121 and the second partition plate 122 and the other of the third partition plate 123 and the fourth partition plate 124.
[0044] Preferably, the two first partition plates 121 or the two second partition plates 122 respectively form the side walls of the two degradation sections 131 at both ends of the flow channel. In this way, it can be ensured that the liquid inlet end and the liquid outlet section of the flow channel face the same direction in the width direction of the inner cavity 111, that is, as Figure 1 shown, both the liquid inlet end and the liquid outlet end of the flow channel face downward. At this time, the liquid inlet 112 and the liquid outlet 113 can be opened on the side of the housing 114 away from the cover 115. Specifically, in the Figure 1 shown embodiment, the two side walls of the degradation section 131 located on the leftmost side are respectively formed by the third partition plate 123 and the first partition plate 121, and the two side walls of the degradation section 131 located on the rightmost side are respectively formed by the fourth partition plate 124 and the first partition plate 121.
[0045] In one embodiment, the electrode includes a first electrode 141 and a second electrode 142, that is, the degradation device 100 includes multiple groups of first electrodes 141 and multiple groups of second electrodes 142, and the number of each group of first electrodes 141 and each group of second electrodes 142 is multiple. Each group of first electrodes 141 and any group of second electrodes 142 are disposed in a corresponding degradation section 131. In the same degradation section 131, the multiple first electrodes 141 and the multiple second electrodes 142 are respectively disposed on the opposite inner walls of the degradation section 131 and are alternately arranged at intervals along the extension direction of the flow channel to form a sub-flow channel 132. Specifically, in the Figure 1 shown embodiment, both the first electrode 141 and the second electrode 142 are plate-shaped, and the first electrode 141 is the positive electrode and the second electrode 142 is the negative electrode.
[0046] In one embodiment, a conductive structure is further provided on the partition 120, and the first electrode 141 and the second electrode 142 are connected to an external power source through the conductive structure. Preferably, one of the first electrode 141 and the second electrode 142 is disposed on the first partition 121, and the other of the first electrode 141 and the second electrode 142 is disposed on the second partition 122.
[0047] It can be determined that two adjacent degradation segments 131 share a first partition 121 or a second partition 122. Therefore, electrodes are disposed on both sides of the first partition 121 and the second partition 122, and one of the first electrode 141 and the second electrode 142 is disposed on both sides of the first partition 121, and the other of the first electrode 141 and the second electrode 142 is disposed on both sides of the second partition 122. In this way, only a conductive structure connected to the positive or negative pole of the external power source needs to be disposed inside the first partition 121 or the second partition 122. If both the first electrode 141 and the second electrode 142 are disposed on the first partition 121 or the second partition 122 at the same time, a conductive structure connected to both the positive and negative poles of the power source needs to be disposed inside the first partition 121 or the second partition 122, which increases the difficulty and also increases the possibility of internal leakage. Specifically, in the illustrated embodiment, the second electrode 142 is disposed on the first partition 121, and the first electrode 141 is disposed on the second partition 122. Similarly, it can be known that the first electrode 141 is disposed on the third partition 123, and the second electrode 142 is disposed on the fourth partition 124. Figure 1 In one embodiment, both the outer shell 110 and the partition 120 are made of corrosion-resistant plastic materials, such as polytetrafluoroethylene, fluoroplastics, etc.; both the first electrode 141 and the second electrode 142 are made of corrosion-resistant metal materials or corrosion-resistant alloy materials, such as iridium, tantalum, copper alloy, stainless steel, etc.
[0048] In one embodiment, the flow channel further includes a plurality of communication segments 133. Each communication segment 133 is located between two adjacent degradation segments 131 along the extending direction of the flow channel and is communicated with the sub-flow channels 132 of the two adjacent degradation segments 131 to realize the zigzag extension of the flow channel.
[0049] Furthermore, the outer shell 110 is further provided with a plurality of sampling ports 116. Each sampling port 116 is communicated with a corresponding communication segment 133. Samples at different positions of the flow channel are obtained through the sampling ports 116, and the treatment result of the wastewater is judged according to the detection of the samples at different positions, and the wastewater flow rate and the electrolysis power can be adjusted according to the treatment result.
[0050] It should be noted that a sampling valve can be provided at each sampling port 116, and the opening and closing of the sampling port 116 are controlled by the control valve.
[0051]
[0052] In summary, the degradation device 100 provided by the present application has at least the following advantages:
[0053] 1. Multiple partitions 120 form a meandering flow channel in the inner cavity 111, and the flow channel has multiple degradation segments 131. Then, in the degradation segments 131, multiple first electrodes 141 and second electrodes 142 form meandering sub-flow channels 132 to extend the flow path of the wastewater in the inner cavity 111, extend the flow time, that is, extend the electrolysis time of the wastewater, thereby improving the electrolytic oxidation effect and achieving a better degradation effect;
[0054] 2. When the wastewater flows in the meandering sub-flow channels 132, it presents a turbulent state, which can improve the mixing effect of the wastewater and the electrolytic oxidation effect of the wastewater;
