Description

Technical Field

[0001] This invention relates to the field of wastewater electrolysis technology, specifically to a wastewater electrolysis cell and a wastewater electrolysis treatment method. Background Technology

[0002] Electrocoagulation uses soluble metal electrodes as anodes. Under an electric field, the anode dissolves, generating a large number of cations that form a series of polynuclear hydroxyl complexes and hydroxides. These cations adsorb and coagulate suspended solids and organic matter in the water. Simultaneously, electrochemical oxidation and reduction reactions occur near the anode and cathode with pollutants. The microbubbles generated by electrolysis also come into contact with suspended solids and rise to the surface to form a scum layer, thus providing a flotation function. Therefore, electrocoagulation offers advantages such as high efficiency and low cost for wastewater treatment.

[0003] In existing wastewater electrolysis cells, such as the Chinese patent CN107098444B, when the micro-electrolysis packing is consumed, it can be restored to use simply by adding new packing, without replacing the electrode plates. This solves the problems of large workload for electrode plate replacement and incomplete utilization of electrode plates in existing electrocoagulation technologies. Through the electrocoagulation reaction extending from the electrode plate surface to the interior of the packing, the reaction sites expand from a two-dimensional plane to a three-dimensional space. In addition, the micro-electrolysis effect of the packing itself provides pollutants in the wastewater with a more sufficient contact area and reaction time. With more reaction sites, high current efficiency, and fast electrochemical reaction speed, the wastewater treatment efficiency per unit volume of equipment is significantly improved. Furthermore, it has a simple structure, stable operation, strong controllability, and small footprint.

[0004] However, the following problems still exist: when wastewater is discharged after treatment, flocculation is easily left at the bottom of the electrolytic cell, which can affect the quality of wastewater treatment the next time.

[0015] A wastewater electrolysis treatment method using the aforementioned wastewater electrolysis cell.

[0016] Compared with the prior art, the present invention provides a wastewater electrolytic cell and a wastewater electrolytic treatment method, which have the following beneficial effects: 1.

After electrolysis, the cell is drained, and simultaneously, a push bar is activated, moving from one end of the cell to the other, pushing the deposited flocculation into an inclined trough. This allows the wastewater to be discharged from the trough carrying the flocculation along with it, effectively cleaning the flocculation within the cell and preventing it from settling and remaining.

[0017] 2. In this wastewater electrolysis cell, through the setting of heat exchange tubes, the liquid pump draws cooling water from the water tank, and the cooling water enters the water delivery joint through the liquid pump and then enters the heat exchange tubes.

[0021] 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.

[0022] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a wastewater electrolytic cell and a wastewater electrolytic treatment method.

[0023] Example 1, a typical implementation of this application, such as Figure 1 As shown, a wastewater electrolytic cell and a wastewater electrolytic treatment method include a frame 1, a treatment mechanism 2 installed on the frame 1, and an auxiliary mechanism 3 installed on the frame 1. The treatment mechanism 2 includes an electrolytic cell 21, an electrode horizontal plate 23, and an electrode side plate 24. An electrolytic cell 21 is provided on the frame 1. An electrode horizontal plate 23 and an electrode side plate 24 are provided inside the electrolytic cell 21. After wastewater flows into the electrolytic cell 21, the wastewater is electrolyzed by the electrode horizontal plate 23 and the electrode side plate 24. The auxiliary mechanism 3 includes a push bar 37 and an inclined trough 310. The push bar 37 is installed in the electrolytic cell 21, and the inclined trough 310 is installed in the electrolytic cell 21. The push bar 37 pushes the flocculated material into the inclined trough 310, and the electrolyzed water carries the flocculated material out together.

[0024] When using this invention: Wastewater is fed into the electrolytic cell 21. The electrode horizontal plate 23 and electrode side plate 24 are activated, and the wastewater is electrolyzed using the positive and negative electrodes of the electrode horizontal plate 23 and electrode side plate 24. This process purifies the wastewater and generates flocculation. After electrolysis, the wastewater in the electrolytic cell 21 is drained. At the same time, the lever 37 is activated, moving from one end of the bottom surface of the electrolytic cell 21 to the other end. The lever 37 pushes the deposited flocculation into the inclined trough 310, so that the wastewater is discharged from the inclined trough 310 along with the flocculation. This effectively cleans the flocculation in the electrolytic cell 21, preventing flocculation from settling and remaining in the electrolytic cell 21. As a result, when the treated wastewater is discharged, flocculation is prevented from remaining at the bottom of the electrolytic cell 21, thus avoiding residual flocculation that could affect the quality of subsequent wastewater treatment. This also reduces the cost of cleaning and maintaining the electrolytic cell 21 and improves the applicability of the equipment.

The overall size of the electrode horizontal plate 23 is smaller than the horizontal cross-sectional size inside the electrolytic cell 21. An electrode side plate 24 is fixedly installed on the side of the electrolytic cell 21. The electrode side plate 24 has an annular square structure. The size of the electrode side plate 24 is adapted to the side wall size of the electrolytic cell 21. The electrode horizontal plate 23 and the electrode side plate 24 are the positive and negative electrodes, respectively.

[0026] Furthermore, a rail frame 25 is fixedly installed at the top of the frame 1. The rail frame 25 is set in two parts and is symmetrically distributed on both sides of the electrolytic cell 21. The length of the rail frame 25 is adapted to the length of the electrolytic cell 21. A suspension 26 is set on the rail frame 25. The two ends of the suspension 26 are slidably engaged with the rail frame 25 on each side. The suspension 26 is located above the electrolytic cell 21. The length of the suspension 26 is adapted to the width of the electrolytic cell 21. A first screw 27 is rotatably engaged in the rail frame 25. The length of the first screw 27 is adapted to the length of the rail frame 25. The first screw 27 passes through the suspension 26 and is threadedly engaged with the suspension 26. A first stepper motor 28 is fixedly installed on the frame 1. The first stepper motor 28 is poweredly connected to the first screw 27.

[0027] Furthermore, the bottom end of the suspension 26 is rotatably fitted with a stirring blade 29, which extends into the electrolytic cell 21. The stirring blade 29 is located above the electrode plate 23, and its size is adapted to the electrolytic cell 21. A second stepper motor 210 is fixedly installed at the top of the suspension 26, and the second stepper motor 210 is poweredly connected to the stirring blade 29.

[0028] Furthermore, a water tank 211 is fixedly installed next to the frame 1, and a liquid pump 212 is fixedly installed on the water tank 211. A water supply connector 213 is fixedly installed on the drain end of the liquid pump 212. The water supply connector 213 is connected to the liquid pump 212. A heat exchange tube 214 is installed on the water supply connector 213. One end of the heat exchange tube 214 is connected to the water supply connector 213, and the other end of the heat exchange tube 214 extends from one side of the electrolytic cell 21 to the bottom of the electrolytic cell 21 and extends out from the other side of the electrolytic cell 21.

[0029] Furthermore, multiple heat exchange fins 215 are fixedly installed on the heat exchange tube 214. The heat exchange fins 215 are located outside the electrolytic cell 21 and are all connected to the heat exchange tube 214. A reflux connector 216 is fixedly installed on the water tank 211. The reflux connector 216 is connected to the water tank 211 and is fixedly connected to the other end of the heat exchange tube 214. The inlet of the liquid pump 212 is connected to the water tank 211.

[0030] In the process of electrolyzing wastewater, the electrode horizontal plate 23 and electrode side plate 24 are first energized to form positive and negative electrodes to electrolyze the wastewater in the electrolysis cell 21. Simultaneously, the first stepper motor 28 is started, driving the first screw 27 to rotate. The first screw 27 drives the suspension 26 to move on the rail frame 25. The second stepper motor 210 is also started, driving the stirring blade 29 to rotate. This causes the stirring blade 29 to reciprocate within the electrolysis cell 21, thus improving the efficiency of wastewater electrolysis. Simultaneously, the water tank 211 is filled with cooling water, and the liquid pump 2 is started. 12. The liquid pump 212 draws cooling water from the water tank 211. The cooling water enters the water supply connector 213 through the liquid pump 212, and then enters the heat exchange tube 214 through the water supply connector 213. The cooling water passes through the heat exchange tube 214 to cool the wastewater from the electrolysis process, preventing the heat generated by the electrolysis process from raising the temperature inside the electrolytic cell 21 and preventing the high temperature from affecting the quality of the electrolysis process. The cooling water then enters the heat sink 215 through the heat exchange tube 214, where it dissipates heat to the air. The cooling water then enters the return connector 216 through the heat sink 215 and then enters the water tank 211.

[0031] Example 3, as Figures 8-12As shown, the difference from the above embodiment is that the auxiliary mechanism 3 also includes a water inlet pipe 31. A water inlet pipe 31 is provided on one side of the frame 1. The water inlet pipe 31 extends to the top of the electrolytic cell 21. The water inlet pipe 31 is connected to the sewage conveying system and is used to convey sewage into the electrolytic cell 21. A drain pipe 32 is provided on the other side of the frame 1. The drain pipe 32 is connected to the bottom of the electrolytic cell 21 and is used to discharge the water after electrolysis.

[0032] Furthermore, a filter pipe 33 is fixedly installed on the drainage pipe 32. The filter pipe 33 is located outside the electrolytic cell 21 and is connected to the drainage pipe 32. A valve 34 is fixedly installed on the filter pipe 33 and is connected to the filter pipe 33.

[0033] Furthermore, side rails 35 are fixedly installed at the bottom of the side walls on both sides of the electrolytic cell 21. The length of the side rails 35 is adapted to the length of the electrolytic cell 21. Moving parts 36 are slidably fitted on the side rails 35. A lever 37 is provided between the moving parts 36 on both sides. The two ends of the lever 37 are fixedly connected to the moving parts 36 on both sides respectively. The bottom end of the lever 37 is in contact with the bottom surface of the electrolytic cell 21. A second screw 38 is rotatably fitted inside the side rails 35. The second screw 38 passes through the moving parts 36 and is threadedly fitted with the moving parts 36. A servo motor 39 is fixedly installed on the frame 1. The servo motor 39 is poweredly connected to the second screw 38. A sloping groove 310 is opened at one end of the bottom surface of the electrolytic cell 21. The sloping groove 310 is adjacent to the drainage pipe 32.

[0034] Wastewater is supplied to the electrolysis cell 21 via the inlet pipe 31, and the water after electrolysis is discharged via the drain pipe 32. After the wastewater is electrolyzed, the valve 34 is opened, and the electrolyzed water is discharged from the drain pipe 32. The electrolyzed water, carrying flocculated material, enters the filter pipe 33 from the drain pipe 32. The flocculated material is filtered by the filter pipe 33, and the electrolyzed water enters the valve 34 from the filter pipe 33 and is discharged. At the same time, the servo motor 39 is started, which drives the second screw 38 to rotate. The second screw 38 drives the moving part 36 to move on the side rail 35. The moving part 36 drives the lever 37 to move, so that the lever 37 moves the flocculated material deposited on the bottom surface of the electrolysis cell 21 from one end of the electrolysis cell 21 to the other end, so that the flocculated material falls into the inclined trough 310, making it easier for the flocculated material to be discharged by the drain pipe 32 in the inclined trough 310. Then, before the next wastewater electrolysis treatment, the lever 37 is reset.

[0035] Working principle of the invention: Wastewater is fed into the electrolytic cell 21. The electrode horizontal plate 23 and electrode side plate 24 are activated, and the wastewater is electrolyzed using the positive and negative electrodes of the electrode horizontal plate 23 and electrode side plate 24. This process purifies the wastewater and generates flocculation. After electrolysis, the wastewater in the electrolytic cell 21 is drained. At the same time, the lever 37 is activated, moving from one end of the bottom surface of the electrolytic cell 21 to the other end. The lever 37 pushes the deposited flocculation into the inclined trough 310, so that the wastewater is discharged from the inclined trough 310 along with the flocculation. This effectively cleans the flocculation in the electrolytic cell 21, preventing flocculation from settling and remaining in the electrolytic cell 21. As a result, when the treated wastewater is discharged, flocculation is prevented from remaining at the bottom of the electrolytic cell 21, thus avoiding residual flocculation that could affect the quality of subsequent wastewater treatment. This also reduces the cost of cleaning and maintaining the electrolytic cell 21 and improves the applicability of the equipment. In the process of electrolyzing wastewater, the electrode horizontal plate 23 and electrode side plate 24 are first energized to form positive and negative electrodes to electrolyze the wastewater in the electrolysis cell 21. Simultaneously, the first stepper motor 28 is started, driving the first screw 27 to rotate. The first screw 27 drives the suspension 26 to move on the rail frame 25. The second stepper motor 210 is also started, driving the stirring blade 29 to rotate. This causes the stirring blade 29 to reciprocate within the electrolysis cell 21, thus improving the efficiency of wastewater electrolysis. Simultaneously, the water tank 211 is filled with cooling water, and the liquid pump 2 is started. 12. The liquid pump 212 draws cooling water from the water tank 211. The cooling water enters the water supply connector 213 through the liquid pump 212. The cooling water enters the heat exchange tube 214 through the water supply connector 213. The cooling water passes through the heat exchange tube 214 to cool the wastewater from the electrolysis process, preventing the heat generated by the electrolysis process from raising the temperature inside the electrolytic cell 21 and preventing the high temperature from affecting the quality of the electrolysis process. The cooling water then enters the heat sink 215 through the heat exchange tube 214. The cooling water dissipates heat to the air in the heat sink 215. The cooling water then enters the return connector 216 through the heat sink 215 and enters the water tank 211 through the return connector 216. Wastewater is supplied to the electrolysis cell 21 through the inlet pipe 31, and the water after electrolysis is discharged through the drain pipe 32. After the wastewater is electrolyzed, the valve 34 is opened, and the electrolyzed water is discharged from the drain pipe 32. The electrolyzed water carrying flocculated material enters the filter pipe 33 through the drain pipe 32. The flocculated material is filtered by the filter pipe 33, and the electrolyzed water enters the valve 34 through the filter pipe 33 and is discharged. At the same time, the servo motor 39 is started, which drives the second screw 38 to rotate. The second screw 38 drives the moving part 36 to move on the side rail 35. The moving part 36 drives the lever 37 to move, so that the lever 37 moves the flocculated material deposited on the bottom surface of the electrolysis cell 21 from one end of the electrolysis cell 21 to the other end, so that the flocculated material falls into the inclined trough 310, making it easier for the flocculated material to be discharged by the drain pipe 32 in the inclined trough 310. Then, before the next wastewater electrolysis treatment, the lever 37 is reset.
