Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water treatment, in particular to an electric flocculation reaction unit and an electric flocculation reaction device. Background Art
[0002] Although traditional water treatment technologies such as physical, chemical and biological methods can remove pollutants in water to a certain extent, they have problems such as unsatisfactory treatment effects, complex operations and high energy consumption. Therefore, it is particularly important to develop an efficient, energy-saving and environmentally friendly water treatment technology.
[0003] As a new type of water treatment technology, electrocoagulation technology has the advantages of good treatment effect, simple operation and low energy consumption. It is widely used in the fields of industrial wastewater, farmland irrigation water and drinking water treatment. Electrocoagulation technology adopts the electrochemical principle and uses alloy metals such as aluminum and iron as the main electrode. It uses external pulse high voltage to produce electrochemical reactions, converts electrical energy into chemical energy, and produces metal cationic flocculants at the expense of anode metal electrodes. It separates pollutants from the water body through coagulation, flotation, reduction and oxidation decomposition to achieve a technology of purifying the water body. However, most of the existing electrocoagulation reaction devices use a box structure and a plate electrode structure, which are complex in structure and occupy a large space, limiting their application in the field of water treatment. In addition, the anode plate is prone to scaling, and the efficiency is low after scaling, and it needs to be replaced regularly. Utility Model Content
[0004] In order to solve the problem of low efficiency in the prior art, the utility model provides an electro-flocculation reaction unit and an electro-flocculation reaction device with improved efficiency.
[0005] The technical solution adopted by the utility model to solve its technical problems is:
[0006] An electro-flocculation reaction unit, comprising:
[0007] A cathode sleeve, wherein the cathode sleeve has a liquid inlet at its lower end and a liquid outlet at its upper end;
[0008] The anode core is arranged in the cathode sleeve, and a channel connecting the liquid inlet and the liquid outlet is formed between the anode core and the cathode sleeve. The anode core includes a body and a plurality of fins distributed along the circumference of the body.
[0009] Furthermore, the fin is provided with at least two branches. By increasing the surface area of the fin, a larger current can be carried per unit time, and the anode core releases more anode metal ions into the water per unit time, and the anode metal ions act as coagulants, thereby achieving higher coagulation or flocculation efficiency.
[0010] Furthermore, the anode inner core and the cathode sleeve axis coincide with each other, which can ensure the position accuracy and uniformity of the flow channel.
[0011] Furthermore, it also includes an insulating spacer for preventing the cathode sleeve from contacting the anode inner core, wherein the insulating spacer is arranged between the cathode sleeve and the anode inner core to prevent the cathode sleeve from contacting the anode inner core.
[0012] Furthermore, the insulating spacer is a mesh spacer sleeved on the outside of the anode inner core, and the inner diameter of the mesh spacer matches the outer diameter of the anode inner core. The mesh spacer occupies a small volume and reduces the shielding of the anode inner core.
[0013] Furthermore, the anode inner core is inserted from the upper end of the cathode sleeve, and the upper end of the anode inner core is detachably fixedly connected to the upper end of the cathode sleeve. The detachable fixed connection mode facilitates the replacement of the anode inner core.
[0014] Furthermore, the length of the anode core is shorter than that of the cathode sleeve, and the mesh separator is only arranged on the outer periphery of the anode core. The bottom of the anode core is not blocked and faces the liquid inlet direction, so that the liquid has a better flushing effect on the anode core, further reducing the possibility of scaling of the anode core.
[0015] An electro-flocculation reaction device comprises a plurality of electro-flocculation reaction units as described above, and further comprises:
[0016] A frame, to which the cathode sleeve and / or anode inner core are fixedly connected;
[0017] A liquid inlet pipe, the liquid inlet pipe is connected with the liquid inlet port;
[0018] A liquid outlet pipe, the liquid outlet pipe is connected to the liquid outlet;
[0019] A pump is arranged on the liquid inlet pipe.
[0020] Furthermore, the cathode sleeve is sleeved with a conductive ring, and adjacent conductive rings are connected by copper plates.
[0021] Furthermore, the anode core is connected to a conductive column, the conductive columns are connected in parallel, and a current detection device is provided on the parallel circuit where the anode core is located. The loss degree of the anode core is monitored by detecting the current on the parallel circuit where the anode core is located, so as to replace the anode core at the corresponding position.
[0022] Beneficial effects:
[0023] (1) The electric flocculation reaction unit of the utility model changes the flocculation structure of the water pool into a pipeline structure, which occupies a small area and is more flexible in application scenarios. The anode inner core adopts a fin structure with a large surface, which can carry a larger current per unit time, so that the anode inner core releases more anode metal ions in the water per unit time, and the anode metal ions act as coagulants, so that the coagulation or flocculation efficiency is higher;
[0024] (2) Branches are set on the fins to maximize the surface area of the anode core;
[0025] (3) A channel connecting the liquid inlet and the liquid outlet is formed between the anode inner core and the cathode sleeve of the electric flocculation reaction unit of the utility model. Water can flow through this channel to flush the surface of the anode inner core, making it difficult for the anode inner core to scale, thereby further improving efficiency;
[0026] (4) By sleeved a mesh separator on the anode core, on the one hand, the length of the anode core and the cathode sleeve is longer, preventing the two from contacting due to installation errors or deformation, etc., on the other hand, the mesh separator occupies a small area and has little effect on the release of ions in the anode core. Finally, the mesh separator matches the outer diameter of the anode core, so that the mesh separator can be directly installed on the anode core to form an assembly, and then installed in conjunction with the cathode sleeve, and the installation process is simple. On the other hand, the mesh separator is attached to the outside of the anode core, rather than being located in the middle of the anode core and the cathode sleeve, which can reduce turbulence. In this way, it will not affect the liquid flow rate in the channel between the anode core and the cathode sleeve, thereby reducing the scouring effect of the liquid on the anode core;
[0027] (5) The electric flocculation reaction device of the utility model is provided with a plurality of reaction units on the frame, and the number and position of the reaction units can be selected according to actual needs, and has good applicability;
[0028] (6) The anode cores are connected in parallel, and the degree of anode core loss can be monitored by detecting the current on the parallel circuit where the anode core is located, so that the anode core at the corresponding position can be replaced to ensure the efficiency of each reaction unit, and the monitorability is high;
[0029] (7) The anode core and cathode sleeve are detachably fixed to facilitate replacement of the anode core. BRIEF DESCRIPTION OF THE DRAWINGS

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.
[0039] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description.

[0042] like Figures 1 to 3 The utility model provides an electro-flocculation reaction unit, including a cathode sleeve 1 and an anode core 2. The material of the anode core 2 may be selected but not limited to aluminum, and the material of the cathode sleeve 1 may be selected but not limited to iron or stainless steel. A liquid inlet 11 is provided at the lower end of the cathode sleeve 1, and a liquid outlet 12 is provided at the upper end of the cathode sleeve 1; the anode core 2 is arranged in the cathode sleeve 1, and a channel connecting the liquid inlet 11 and the liquid outlet 12 is formed between the anode core 2 and the cathode sleeve 1. The anode core 2 includes a body 21 and a plurality of fins 22 distributed along the circumference of the body 21. Preferably, the fins 22 are evenly distributed along the circumference of the body 21. At least two branches 221 are provided on the fin 22. In the utility model, the fin 22 has two branches, and the cross section of the fin 22 is Y-shaped. In order to ensure the position accuracy and uniformity of the flow channel, the anode core 2 coincides with the axis of the cathode sleeve 1.
[0043] The electro-flocculation reaction unit further comprises an insulating spacer 3 for preventing the cathode sleeve 1 and the anode inner core 2 from contacting each other. The insulating spacer 3 is arranged between the cathode sleeve 1 and the anode inner core 2 .
[0044] The insulating spacer 3 is preferably a mesh spacer sleeved on the outside of the anode core 2. The inner diameter of the mesh spacer matches the outer diameter of the anode core 2, and can be fixedly connected to the anode core 2 by bonding or other means. The anode core 2 is inserted from the upper end of the cathode sleeve 1, and the upper end of the anode core 2 is detachably fixedly connected to the upper end of the cathode sleeve 1. The length of the anode core 2 is smaller than the cathode sleeve 1, and the mesh spacer is only arranged on the outer periphery of the anode core 2. During installation, the mesh spacer can be first installed on the anode core 2 to form an assembly, and then the assembly can be connected to the cathode sleeve 2 as a whole. In addition to using a mesh isolation member, the insulating isolation member 3 may also use other structural forms, and the shape may be a polygon or a grid shape, etc., or as another embodiment, the insulating isolation member 3 may be spiral-shaped and have a certain width, such as greater than 1 / 2 of the distance between the cathode sleeve 1 and the anode core 2. In this way, the insulating isolation member 3 not only plays an insulating role, but also guides the liquid, and the liquid can flow quickly along the spiral flow channel. On the one hand, the liquid has a fast flow rate in the cathode sleeve 1 and a long residence time. The water flow has an impact force that directly rushes toward the anode core 2 in the radial direction, further enhancing the flushing effect of the liquid on the anode core 2 and preventing scaling of the anode core 2.
[0045] like Figure 4The utility model also provides an electro-flocculation reaction device, including a plurality of the above-mentioned electro-flocculation reaction units 10, the anode core 2 is connected to a conductive column 8, the conductive columns 8 are connected in parallel, and a current detection device is provided on the parallel circuit where the anode core 2 is located. A conductive ring 7 is sleeved on the cathode sleeve 1, and adjacent conductive rings 7 are connected by a copper plate. It also includes a frame 4, a liquid inlet pipe 5, a liquid outlet pipe 6 and a pump 9, the cathode sleeve 1 and / or the anode core 2 are fixedly connected to the frame 4, the cathode sleeve 1 can be fixed to the frame 4, and then the anode core 2 is installed on the cathode sleeve 1, or the anode core 2 can be fixed to the frame 4 by hoisting, and then the cathode sleeve 1 is sleeved on the outside of the anode core 2 from below. Considering the heavy weight of the anode core 2, it is preferred to fix the conductive column 8 on the frame 4 by hoisting the anode core 2. The specific fixing structure is not shown in the attached figure, and a beam and other structures can be fixed on the frame 4. This method can ensure the position accuracy of the anode core 2 and the overall structural stability is better;
[0046] The liquid inlet pipe 5 is connected to the liquid inlet 11, the liquid outlet pipe 6 is connected to the liquid outlet 12, and the pump 9 is arranged on the liquid inlet pipe 5. In the utility model, the pump 9 adopts a large-flow circulation pump 9. The large-flow liquid can better flush the anode core 2 and further prevent scaling; a valve can be set before each liquid inlet 11, so that a specific number and position of reaction units can be selectively selected for electrocoagulation.
[0047] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
