Description

Technical Field

[0001] The utility model relates to the technical field of electrolysis, in particular to a spiral high-efficiency electrolysis module and an electrochemical reaction device. Background Art

[0002] Boron-doped diamond (BDD) electrode is made by depositing a boron-doped diamond film on a substrate using a vapor deposition method. When powered on, the effective components produced by electrolyzing water in water are ozone and hydroxyl radicals, which can oxidize viruses, bacteria, organic pollutants, etc.

[0003] At present, the existing BDD electrolysis module structures on the market are almost all flat plate structures. The water flow direction is parallel to the electrode plate. The water flow into the module is almost laminar flow, undisturbed, and the water flow and mass transfer directions are perpendicular to each other, which seriously affects the mass transfer. Most of the wastewater degradation is indirect oxidation, and the direct oxidation part is very small. Therefore, the current efficiency of such modules is low. Traditionally, in order to increase the degradation efficiency of the electrolysis module, gas is introduced into the electrolysis module for air stirring, which not only increases the cost, but also has little effect, and the cost performance is not high.

[0004] Therefore, there is an urgent need for a decomposition module and an electrochemical reaction device that can effectively improve the degradation efficiency. Utility Model Content

[0005] The utility model aims to provide a solution module and an electrochemical reaction device, aiming to solve the technical problem of low electrolysis efficiency of traditional electrolysis modules.

[0006] To achieve the above objectives, in a first aspect, the utility model provides an electrolysis module, comprising:

[0007] A shell, a water inlet disposed at one end of the shell, and a water outlet disposed at the other end of the shell;

[0008] A plurality of anode plates and / or cathode plates are arranged in parallel in the shell, and the anode plates and / or cathode plates are arranged staggered along the water flow direction, and a plurality of spiral spoilers are arranged in sequence between adjacent anode plates and / or cathode plates along the water flow direction, and the spiral spoilers are rotatably arranged on both sides of the shell;

[0009] When the plurality of spiral spoilers are used as anode plates or cathode plates, the plurality of spiral spoilers are electrically connected in series with each other;

[0010] The spiral spoiler comprises a spoiler shaft and a spoiler spiral blade arranged on the spoiler shaft, and the spoiler shaft is rotatably connected to the housing;

[0011] The spoiler spiral blades can cover the width direction of the corresponding anode plate or cathode plate.

[0012] As a further improvement of the above solution, the anode plate and / or the cathode plate are preferably BDD electrodes.

[0013] As a further improvement of the above solution, the electrolysis module also includes a power supply, and the anode plate and the cathode plate are electrically connected to the power supply respectively.

[0014] In a second aspect, the utility model further provides an electrochemical reaction device, comprising the above-mentioned electrolysis module, a water inlet device and a spiral reaction mixer,

[0015] The water inlet device is connected to the water inlet at one end of the shell, and the water inlet device includes a water pump;

[0016] The spiral reaction mixer is connected to the water outlet at the other end of the shell.

[0017] As a further improvement of the above scheme, the spiral reaction mixer includes a mixer body and an S-shaped flow channel arranged in the mixer body, and a spiral mixing element for uniform mixing is arranged in the straight section of the S-shaped flow channel.

[0018] As a further improvement of the above scheme, the mixer body comprises an upper cover and a lower cover sealed with the upper cover, the inner wall of the upper cover is provided with an S-shaped flow channel upper groove, and the inner wall of the lower cover is provided with an S-shaped flow channel lower groove matching the S-shaped flow channel upper groove;

[0019] When the upper cover and the lower cover are buckled together, the upper groove of the S-shaped flow channel and the lower groove of the S-shaped flow channel form the S-shaped flow channel.

[0020] As a further improvement of the above solution, the spiral mixing element includes a mixing shaft and a mixing spiral blade arranged on the mixing shaft.

[0021] As a further improvement of the above solution, the spiral reaction mixer further comprises a fastening assembly and a sealing assembly, wherein the sealing assembly is arranged between the upper cover and the lower cover, and the fastening assembly is used to press the upper cover and the lower cover into one body.

[0022] Specifically, taking the case where both the anode plate and the cathode plate use BDD electrodes as an example, the specific process of the electrolysis module degradation is as follows:

[0023] S1: Start the water pump and make the BDD anode plate and the BDD cathode plate in an energized state, and the water pump pumps water into the inner cavity of the shell;

[0024] S2: The water flow drives a plurality of spiral spoilers disposed between the BDD anode plate and the BDD cathode plate to rotate, and the spiral spoilers disturb the water flow and throw the disturbed water flow onto the corresponding BDD anode plate and / or the corresponding BDD cathode plate for direct oxidation electrolysis;

[0025] S3: The water after oxidation electrolysis enters the spiral reaction mixer through the water outlet at the other end of the shell for full mixing; when the water after oxidation electrolysis enters the S-shaped flow channel of the spiral reaction mixer, the water flow pushes the spiral mixing element arranged in the S-shaped flow channel to make it react more fully.

[0026] Since the utility model adopts the above technical solution, the beneficial effects of this application are:

[0027] 1. The utility model provides an electrolysis module, comprising: a shell, a water inlet arranged at one end of the shell, and a water outlet arranged at the other end of the shell; a plurality of anode plates and / or a plurality of cathode plates are arranged in parallel in the shell, the anode plates and / or the cathode plates are arranged staggered along the water flow direction, a plurality of spiral spoilers are arranged in sequence between adjacent anode plates and / or cathode plates along the water flow direction, and the spiral spoilers are rotatably arranged on both sides of the shell; when the plurality of spiral spoilers are used as anode plates or cathode plates, the plurality of spiral spoilers are electrically connected to each other. The spiral spoiler comprises a spoiler shaft and a spoiler spiral blade arranged on the spoiler shaft, and the spoiler shaft is rotatably connected to the shell; the spoiler spiral blade can cover the width direction of the corresponding anode plate or cathode plate; in the utility model, in some preferred embodiments, a spiral spoiler is arranged between the anode and cathode plates to disturb the water flow between the anode and cathode, and the spiral spoiler is arranged along the water flow direction, which not only increases the mass transfer rate of the anode and cathode but also allows the water to be disturbed and thrown onto the corresponding electrode plate for direct oxidation, thereby improving the wastewater degradation efficiency;

[0028] In some embodiments, a plurality of the spiral spoilers are electrically connected in series to serve as anode plates or cathode plates, which can further reduce costs and save traditional anode plates or cathode plates while increasing the anode and cathode mass transfer rate and mixing to improve wastewater degradation efficiency;

[0029] In addition, although the utility model adds a spiral spoiler, which increases a certain cost, the manufacturing process of the spiral spoiler is mature and low-cost, and will not increase the cost of the electrolysis module. On the contrary, since the spiral spoiler can improve the degradation efficiency when degrading the same wastewater under the same conditions, the electrode area can be reduced, thereby reducing the number of positive and negative electrode plates set in the shell, and indirectly reducing the cost of the electrochemical reaction device. Compared with the traditional method of introducing gas into the electrolysis module for stirring, the utility model does not increase the cost of the electrochemical reaction device while ensuring the electrolysis effect; at the same time, the spiral spoiler does not require additional power to drive the device to rotate, and can automatically rotate and work under the action of water flow, and will not increase additional costs; therefore, the electrolysis module provided by the utility model can effectively improve the degradation efficiency without increasing additional costs.

[0048] Embodiment 1:

[0049] See also Figure 1-Figure 5 The utility model provides an electrolysis module, comprising:

[0050] A housing 1, a water inlet 11 arranged at one end of the housing 1, and a water outlet 12 arranged at the other end of the housing 1;

[0051] A plurality of anode plates and a plurality of cathode plates are arranged in parallel in the shell 1. In the present embodiment, the anode plates and the cathode plates are both BDD electrodes, and the following description is made with reference to the BDD anode plate 2 and the BDD cathode plate 3 respectively; the BDD anode plates 2 and the BDD cathode plates 3 are arranged alternately along the water flow direction, and a plurality of spiral spoilers 4 are sequentially arranged between adjacent BDD anode plates 2 and BDD cathode plates 3 along the water flow direction, and the spiral spoilers 4 are rotatably arranged on both sides of the shell 1;

[0052] The electrochemical reaction device further includes a power supply 6, and the anode plate and the cathode plate are electrically connected to the power supply 6 respectively, for supplying power to the BDD anode plate 2 and the BDD cathode plate 3;

[0053] In this embodiment, two BDD anode plates 2 and three BDD cathode plates 3 are arranged in the housing 1. The three BDD cathode plates 3 are arranged in parallel with the two BDD anode plates 2 in an alternating manner. For ease of description, see Figure 1 , from left to right are the first BDD cathode plate 3, the first BDD anode plate 2, the second BDD cathode plate 3, the second BDD anode plate 2 and the third BDD cathode plate 3, a group of spiral spoilers 4 are arranged between the first BDD cathode plate 3 and the first BDD anode plate 2, a group of spiral spoilers 4 are arranged between the first BDD anode plate 2 and the second BDD cathode plate 3, a group of spiral spoilers 4 are arranged between the second BDD cathode plate 3 and the second BDD anode plate 2, and a group of spiral spoilers 4 are arranged between the second BDD anode plate 2 and the third BDD cathode plate 3, each group of spiral spoilers 4 includes a plurality of spiral spoilers 4, each of the spiral spoilers 4 includes a spoiler shaft 41 and a spoiler spiral blade 42 arranged on the spoiler shaft 41, and the spoiler shaft 41 is rotatably connected to the shell 1;

[0055] The utility model is provided with a spiral spoiler 4 between the anode and cathode plates to disturb the water flow between the anode and cathode. At the same time, the spiral spoiler 4 is arranged along the water flow direction, which not only increases the anode and cathode mass transfer speed but also disturbs the water and throws it onto the corresponding electrode plate for direct oxidation, thereby improving the wastewater degradation efficiency.

[0056] In addition, although the present invention adds a spiral spoiler 4, which increases a certain cost, the manufacturing process of the spiral spoiler 4 is mature and low-cost, and does not increase the cost of the electrochemical reaction device.
