Description

Technical Field

[0001] This invention relates to the field of wastewater electrolysis, specifically to an electrochemical water treatment device. Background Technology

[0002] As major industrial water consumers, thermal power plants rely heavily on circulating cooling water systems, which account for 70% to 80% of their total water consumption during normal operation. Therefore, to maximize the reuse of circulating cooling water, while ensuring that the water does not scale or corrode pipes, increasing the concentration ratio of the circulating cooling water system can achieve the goal of water conservation.

[0003] Increasing the concentration ratio of circulating cooling water can significantly reduce the amount of fresh water used and wastewater discharged, while also reducing the amount of scale inhibitors and corrosion inhibitors used, thereby lowering power generation costs. However, a higher concentration ratio is not always better. As the concentration ratio continues to increase, the salts in the circulating cooling water will gradually reach or exceed saturation, eventually forming scale on the condenser surface, thus reducing the cooling effect of the condenser.

[0004] The main characteristics of power plant circulating water discharge are as follows: (1) High salt content. Generally, the circulating water discharge from the cooling tower needs to be highly compressed, which increases the salt ion concentration. (2) High water temperature. Generally, circulating water discharge is set up before the cooling tower and after the condensate. The water temperature here is high, which can reduce the load on the cooling tower. (3) High organic matter content. Because the concentration rate increases during the circulation process, the water treatment time is increased, which will cause a large amount of bacteria and algae to grow in the water. (4) High impurity content. When the water is cooled, it will carry some impurities from the air, mainly including dust, silt, etc., as well as impurities that have been corroded and detached from the equipment. It also contains chemical agents such as scale inhibitors, dispersants, bactericides, and corrosion inhibitors.

[0005] As early as the 1940s, the use of electrolysis technology to treat wastewater was proposed, but its development was slow due to power shortages and high costs. In the early 1960s, with the rapid development of the power industry, electrochemical water treatment technology attracted attention. Since the 1980s, with a deeper understanding of environmental science and increasingly stringent environmental requirements, electrochemical treatment technology has attracted great interest from environmentalists both domestically and internationally due to its advantages. Electrochemical equipment has five major functions: descaling, scale inhibition, sterilization, algae removal, and corrosion prevention. It can adsorb hardness and alkalinity in the water as solid scale within the electrochemical equipment, reducing the hardness of circulating water. Simultaneously, it utilizes the "lattice distortion" and "polarization" effects of electromagnetic fields to prevent residual hardness from forming scale, achieving scale inhibition. It can also use electrochemical reactions to convert chloride ions in water into hypochlorous acid and produce strong oxidizing substances such as hydrogen peroxide and ozone. Combined with an electric field and a strong acid / alkali environment, this achieves sterilization. Furthermore, electrochemical equipment can reduce corrosion from chloride ions and microorganisms, and can disrupt the "galvanic cell" effect to achieve corrosion inhibition. Currently, the application of electrochemical methods for treating circulating water and preventing scale buildup in heat exchangers has made significant progress in China, and is gradually moving towards automation, intelligence, and large-scale development. It is believed that electrochemical methods will also have good application prospects for circulating water treatment in the future.

[0006] Scale inhibition and removal principle.

[0007] Strong reduction reaction at the cathode:

[0008] Under the influence of an electric field, a reduction reaction occurs near the cathode of the electrochemical device, causing calcium and magnesium ions to precipitate in solid form, reducing water hardness and alkalinity, thus achieving a descaling effect. The main reaction equation at the cathode is:

[0009] ① The alkaline environment at the cathode is generated

[0010] 2H₂O + 2e - → 2OH - + H2↑

[0011] ② Formation of carbonate ions

[0012] CO2 + OH - -→HCO3 -

[0013] HCO3 - + OH - CO3 2- + H2O

[0014] ③ Calcium carbonate and magnesium hydroxide precipitate out:

[0015] Ca 2+ + CO3 2- →CaCO3↓

[0016] Mg 2+ + 2OH - →Mg(OH)2↓

[0017] Electric field polarization effect:

[0018] Under the influence of an electric field, water molecules undergo polarization, breaking down from large molecular clusters into smaller, reduced water molecules. This enhances the solubility and permeability of the water, thus inhibiting and dissolving scale.

[0019] Lattice distortion: Under the influence of an electric field, the crystallization process of CaCO3 is altered, causing it to form loose, foamy aragonite-structured soft scale, while inhibiting the formation of dense, calcite-structured hard scale. It exhibits excellent scale inhibition properties.

[0020] Most existing electrode plates are fixed in the electrolytic cell, making it difficult to remove them for cleaning of the soft scale. Over time, the scale buildup on the electrode plates affects the efficiency of the electrolytic cell. Some patents, such as Chinese Patent CN108557962A which discloses an electrochemical water treatment device, allow the electrode plates to be loosened, but cannot be removed and moved to the edge of the electrolytic cell, causing maintenance difficulties. Furthermore, the fixed positions of the electrode plates and the ion exchange membrane prevent targeted adjustments based on different types of wastewater, making it impossible to determine whether to use the ion exchange membrane or adjust the flow channel arrangement, thus lacking universal applicability.

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figure 1-9To address the issue that existing electrolytic cells mostly have fixed electrode plates and ion exchange membranes, which are inconvenient for maintenance and cannot be adjusted for different types of wastewater, a frame assembly is used to install electrode plates or ion exchange membranes of different sizes without the need for separate fixing. The spacing between electrode plates or between an electrode plate and an ion exchange membrane can be adjusted via the slide 2. The positioning assembly 3 can control the electrode plates to be positioned to the left or right, thus forming different flow channels. When the electrode plates are the same width as the electrolytic cell, the height of the main support 1 or the water level can be adjusted to meet the electrolysis requirements of different wastewaters. The lifting and lowering of the main support 1 enables comprehensive maintenance of the electrode plates and ion exchange membranes. The translation part of the upper slide 2 allows individual electrode plates to be removed and transported to the side of the electrolytic cell, facilitating subsequent descaling and other maintenance work. This invention provides a technical solution: an electrochemical water treatment device, comprising a main support 1 and upper slides 2. Two main supports 1 are symmetrically arranged and installed above an electrolytic cell. They can be raised and lowered using methods such as cylinder gantry cranes. Multiple upper slides 2 are slidably connected to the main supports 1. Each upper slide 2 has a frame assembly underneath, in which electrode plates or ion exchange membranes are installed. Each frame assembly consists of two frames 4, whose relative positions can be adjusted to accommodate electrode plates or ion exchange membranes of different sizes. A positioning component 3 is installed on the frame assembly and connected to the upper slide 2. The positioning component 3 can fix the position of one of the frames 4 relative to the upper slide 2, thereby achieving different flow channel arrangements. In this application, electrical components such as motors, cylinders, and push rods all use existing models. In use, the electrode plates and ion membranes are installed into the frame assembly. The upper slide 2 is used to slide on the main support 1 to adjust the spacing between the electrode plates. The positioning assembly 3 is used in conjunction with the flow channel shape determined according to the wastewater conditions. After adjustment, the main support 1 is lowered to complete the installation. When it is necessary to replace or repair a single electrode plate, the upper slide 2 is used to flip the frame assembly containing the corresponding electrode plate and move it out for inspection and maintenance. When it is necessary to carry out overall inspection and maintenance at the end of the year, the main support 1 is raised to lift all the electrode plates and ion membranes for inspection and maintenance.

[0046] To facilitate the installation of different electrode plates, the frame 4 is U-shaped. Each frame 4 has a frame slider 402 fixedly connected to both ends. A frame groove 404 is provided next to the frame slider 402. The frame slider 402 slidably connects to the frame groove 404 of another frame 4 in the same frame assembly. One end of the frame spring 403 is fixedly connected to the frame slider 402, and the other end of the frame spring 403 is fixedly connected to the wall of the frame groove 404. A baffle 401 is also provided on the frame 4 to prevent the electrode plate or ion membrane from slipping off, ensuring its stable installation on the frame assembly. When installation is required, the two frames 4 are pushed to separate and open back-to-back. The two frames 4 drive the frame slider 402 to slide, stretching the frame spring 403. At this time, the motor plate or ion membrane is installed. Then, the two frames 4 are released, and under the action of the spring, they move closer together, clamping the electrode plate or ion membrane, achieving the purpose of adapting to different electrode plates and ion membranes, and facilitating subsequent replacement of electrode plates or ion membranes.

[0047] To facilitate the adjustment of the electrode plate position to form different flow channels, a positioning assembly 3 is provided. The positioning assembly 3 includes an adjustment part and a locking part. The adjustment part is connected to the upper slide 2, and two locking parts are provided at the bottom of the adjustment part. Each locking part is connected to a frame 4. The adjustment part includes a positioning shaft 301. The upper end of the positioning shaft 301 is rotatably connected to the translation slider 209, the middle part is rotatably connected to the positioning box 302, and the lower end is fixedly connected to two shaft sprockets 303. The positioning shaft 301 is positioned by ball springs set in the positioning box 302. To facilitate rotation and position determination, a handle is provided on the positioning shaft 301. Each shaft sprocket 303 is connected to an acceleration sprocket 304 through a chain. Two meshing steering bevel gears 305 are provided under the acceleration sprocket 304. One steering bevel gear 305 is fixedly connected to the acceleration sprocket 304, and the other steering bevel gear 305 is fixedly connected to a large sprocket 306. The acceleration sprocket 304, steering bevel gear 305, and large sprocket 306 are rotatably connected in the positioning box 302. The locking part includes a positioning block 309, an extension rod 310 fixedly connected to the lower part of the positioning box 302, a fixed shaft 311 fixedly connected to each side of the extension rod 310, a positioning block 309 slidably connected in the fixed shaft 311, an auxiliary wheel 312 rotatably connected to the outside of the fixed shaft 311, the auxiliary wheel 312 rolls in the positioning groove 405, the positioning groove 405 is set on the frame 4, the large sprocket 306 drives the small sprocket 307 to rotate through the chain, the small sprocket 307 is fixedly connected to the middle part of the positioning screw 308, a positioning block 309 is threaded to each end of the positioning screw 308, and the small sprocket 307 and the positioning screw 308 are rotatably connected in the extension rod 310. When it is necessary to move the electrode plate closer to one side of the electrolytic cell, first rotate the positioning shaft 301 so that both locking parts are not locked. At this time, slide the side of the frame 4 that needs to be close to the cell wall closest to the U-shaped opening under the locking part. Then continue to rotate the extension rod 310 to lock the position of the frame 4. During this process, the positioning shaft 301 drives the shaft sprocket 303 to rotate, the shaft sprocket 303 drives the acceleration sprocket 304 to rotate, the acceleration sprocket 304 drives the steering bevel gear 305 to rotate, the two steering bevel gears 305 rotate synchronously, and the steering bevel gear 305 drives the large sprocket 306 to rotate, the large sprocket 306 drives the small sprocket 307 to rotate. The small sprocket 307 drives the positioning screw 308 to rotate. The rotation of the positioning screw 308 causes the positioning block 309 to slide in the extension rod 310. When the positioning block 309 is fully extended, it just abuts against the inner wall of the positioning groove 405, thus forming a positioning. To achieve a better positioning effect, rubber blocks or the like can be set on the positioning block 309 to increase friction, or positioning holes can be set at the corresponding positions of the positioning groove 405 so that the positioning block 309 can be inserted into them. The two locking parts cannot be locked at the same time. If one side is locked, the other side must be unlocked. In the unlocked state, when the frame 4 slides relative to the other side, the auxiliary wheel 312 assists in the sliding.

[0048] To facilitate the movement of the upper slide 2, a traveling mechanism is provided at both ends of the upper slide 2. The traveling mechanism drives the upper slide 2 to slide on the main support 1. The upper slide 2 is also provided with a translation mechanism, which drives the frame assembly to move for maintenance. The traveling mechanism includes a cylinder 201 and a slide wheel 202. The cylinder 201 is fixedly connected to both ends of the upper slide 2, and the output end of the cylinder 201 is rotatably connected to the slide wheel 202. When it is necessary to adjust the spacing between the electrode plates, the cylinder 201 is activated, which drives the slide wheel 202 to extend until the slide wheel 202 touches the main support 1. The cylinder 201 is then activated again to lift the upper slide 2 away from the main support 1, at which point the upper slide 2 can be moved. When it reaches the appropriate position, the cylinder 201 is retracted until the slide wheel 202 leaves the main support 1. At this point, the upper slide 2 is stably placed on the main support 1, completing the adjustment.

[0049] To facilitate the maintenance of individual electrode plates, a translation section is provided, which includes a translation spline shaft 203 and a translation spiral shaft 204. A translation slider 209 is slidably connected to the translation spline shaft 203. One end of a translation guide block 210 is slidably connected to one side of the translation slider 209, and the other end of the translation guide block 210 is slidably connected to a spiral groove on the translation spiral shaft 204. One end of a guide block spring 211 is fixedly connected to the translation guide block 210, and the other end of the guide block spring 211 is fixedly connected to the translation slider 209. The translation spline shaft 203 and the translation spiral shaft 204 are rotatably connected to the upper slide 2. Both ends of the upper slide 2 are provided with drive caps, and the rotation of the translation spline shaft 203 and the translation spiral shaft 204 is controlled by the drive caps. The drive cap includes a translation sleeve 207, the middle of which is rotatably connected to the upper slide 2. One end of the translation sleeve 207 extending into the upper slide 2 is fixedly connected to a translation gear 206. A translation spring 208 is provided between the translation gear 206 and the upper slide 2. One end of the translation spring 208 is always rotatably connected to the translation gear 206, and the other end is fixedly connected to the upper slide 2, so that the translation gear 206 can mesh with the helical shaft gear 205 when it is not under force. The translation gear 206 and the translation sleeve 207 are sleeved on the upper slide 2. Outside the spline shaft 203, the spline on the spline shaft 203 is divided into three sections. The two sections at both ends are slidably connected to the translation gears 206 and translation sleeves 207 on the left and right sides, respectively. The middle spline is slidably connected to the translation slider 209. A bracket is provided between two adjacent spline sections to support the spline shaft 203, so that the spline shaft 203 can only rotate and not slide in the upper slide 2. The translation helical shaft 204 is fixedly connected to the helical shaft gear 205, which can mesh with the translation gear 206.In use, first press the translation sleeve 207. The translation sleeve 207 drives the translation gear 206 to move. The translation gear 206 stretches the translation spring 208. During this process, the translation gear 206 and the spline sleeve inside the translation sleeve 207 are not engaged with the helical shaft gear 205. At this time, rotate the translation sleeve 207. The translation sleeve 207 drives the translation gear 206 to rotate. The translation gear 206 drives the spline shaft 203 to rotate. The spline shaft 203 drives the translation slider 209 to rotate. The translation slider 209 drives the positioning component 3 to rotate. The positioning component 3 drives the frame component to rotate. The frame component drives the electrode plate to rotate. The electrode plate rotates 180° around the spline shaft 203, that is, the electrode plate moves from below the upper slide 2 to above the upper slide 2. During this process, the translation guide block 210 on the translation slider 209 encounters an obstacle and retracts under force, thereby compressing the guide block spring. 211. After the electrode plate has rotated, the translation guide block 210 is inserted into the spiral groove on the translation spiral shaft 204. At this time, the translation sleeve 207 is released and reset under the action of the spring. The translation sleeve 207 is rotated forward or backward as needed, so that the electrode plate moves to one side. The translation sleeve 207 drives the translation gear 206 to rotate, the translation gear 206 drives the spiral shaft gear 205 to rotate, the spiral shaft gear 205 rotates and causes the translation guide block 210 to move. The translation guide block 210 drives the translation slider 209 to move, and the translation slider 209 moves the electrode plate to a suitable position for maintenance. After maintenance is completed, the translation sleeve 207 is reversed to move the electrode plate to its original position and then flipped back to the electrolytic cell. During this process, in order to ensure that the electrode plates on both sides are not hit, the position of the upper slide 2 on the main support 1 can be moved to ensure sufficient flipping distance.
