Description
Technical Field
[0001] The invention relates to the technical field of sodium perchlorate preparation, in particular to a plate-net type electrolytic cell for preparing sodium perchlorate. Background Art
[0002] The plate-net electrolytic cell adopts a plate-net electrode structure. The electrolytic cell plays a key role in the preparation of sodium perchlorate. The principle of electrolysis is used to convert electrical energy into chemical energy or thermal energy, so that an oxidation reaction occurs at the interface between the anode and the solution, and a reduction reaction occurs at the interface between the cathode and the solution to produce the desired sodium perchlorate product. The design of the plate-net electrolytic cell helps to increase the working surface area of the electrode, improve the electrolysis efficiency, and facilitate the escape of bubbles, thereby reducing the bubble effect.
[0003] Since certain gases (such as hydrogen, chlorine, etc.) are generated during the electrolysis process, if the current density is unevenly distributed on the anode and cathode surfaces during this process, it will lead to uneven gas precipitation at the anode and cathode, which will cause uneven local heat distribution in the electrolytic cell and bubble aggregation of the precipitated gas, resulting in a decrease in the reaction rate of sodium perchlorate preparation and a decrease in product quality. In addition, during the electrolysis process, due to the gas, precipitate and other impurities generated in the electrolysis reaction, a layer of dirt or sediment will form on the surface of the nickel wire mesh, which will affect its conductivity and electrolysis efficiency. In order to avoid accumulation, the staff needs to remove the cover plate and then reach into the inside of the electrolytic cell for cleaning, which has a large range of motion and low cleaning efficiency.
[0004] In addition, the preparation process of sodium perchlorate generally involves an electrolysis reaction. During the electrolysis of the sodium chlorate solution, the anode chlorine ions are discharged to mainly generate chlorate ions, and some chlorine ions directly generate chlorine gas, while the cathode is discharged with hydrogen ions to generate hydrogen gas. However, during the generation of chlorine gas in the anode chamber, when the concentration is high, the anode plate is easily corroded, thereby reducing the service life of the anode plate.

[0039] Wherein: the inner wall of the top end of the air outlet pipe 3 is clamped with a sealing plug, and the vertical section of the guide rail 121 is L-shaped;
[0040] Better: inject the sodium chlorate solution to be electrolyzed into the electrolytic cell body 1, and energize the positive and negative electrodes through the power supply, so that the sodium chlorate solution undergoes electrolysis reaction in the cathode chamber 10 and the anode chamber 9 through the cathode plate 8 and the anode plate 7, and arrange an ultrasonic sensor 122 in the middle of the diaphragm 11 to monitor the precipitated gas in the anode chamber 9 and the cathode chamber 10 in real time, and analyze its position and morphology. When uneven gas precipitation is detected and bubbles gather, the ultrasonic sensor 122 transmits this abnormal situation through an electrical signal, controls the rotation of the propellers 123 on both sides through the control panel 4, and transmits the rotational force through the pulley 124 and the connecting belt 125, so that the main bevel gears 126 connected to the diaphragm 11 on both sides rotate synchronously.
[0041] The inside of the electrolytic cell body 1 is horizontally connected with three auxiliary bevel gears 127 which are rotatably connected from left to right in sequence. One of the auxiliary bevel gears 127 is meshedly connected with the main bevel gears 126 on both sides of the middle part and is rotatably connected to the top of the diaphragm 11. The top of the auxiliary bevel gear 127 is fixedly connected with a transmission gear 128. Both sides of the transmission gear 128 are meshedly connected with racks 129.

[0043] Better: With the rotation of the main bevel gears 126 on both sides, the meshing auxiliary bevel gears 127 are driven to rotate in the middle of the diaphragm 11, so that the transmission gear 128 fixedly connected to the auxiliary bevel gear 127 can rotate with it. With the auxiliary support of the guide rails 121 on both sides, the meshing racks 129 on both sides can be driven to move closer to or away from each other in the horizontal direction through the rotation of the transmission gear 128, thereby driving the anode plate 7 and the cathode plate 8 to slide on the outer walls of the guide rails 121 on both sides, so that the heat in the electrolytic cell body 1 can be neutralized by adjusting the distance between the cathode plate 8 and the anode plate 7. , avoiding the accumulation of hydrogen and chlorine bubbles in the cathode chamber 10 and the anode chamber 9, which is conducive to the uniform precipitation of the gas. At the same time, with the rotation of two of the main bevel gears 126, the other two main bevel gears 126 arranged on both sides of the inner wall of the electrolytic cell body 1 can also rotate along, and respectively drive the reciprocating screws 1210 on both sides to rotate inside the cathode chamber 10 and the anode chamber 9 through the corresponding sub-bevel gears 127 meshing with them, and further, with the assistance of the limiting rods 1211 on both sides, the rollers 1212 on both sides threadedly connected to the outer wall of the reciprocating screw 1210 can be driven to move up and down to clean the outer wall mesh of the nickel wire mesh 6 on both sides.
[0044] The anode protection adjustment component includes a chlorine gas detector 131, which is fixedly connected to the inner wall of the anode chamber 9. The insides of the air outlet pipes 3 on both sides are fixedly connected with gas collecting covers 132, and the insides of the air collecting covers 132 on both sides are fixedly connected with fans 133. The top of the air collecting cover 132 close to the anode chamber 9 is fixedly connected with a multi-slot hollow column 134, and the inside of the multi-slot hollow column 134 is fixedly connected with an electric telescopic rod 135. The driving end of the electric telescopic rod 135 is fixedly connected with a movable block 136, and the movable block 136 is slidably connected to the inner wall of the multi-slot hollow column 134. The outer wall of the movable block 136 is evenly rotated around a circle and connected with a plurality of adjusting rods 137. The inner wall of the air outlet pipe 3 close to the anode chamber 9 is fixedly connected to the inner wall of the multi-slot hollow column 134. A three-way cavity plate 138 is connected, and a plurality of rectangular holes 139 are evenly opened at the bottom of the three-way cavity plate 138. The end of the adjusting rod 137 away from the movable block 136 is slidably connected to the inner wall of the rectangular hole 139, and the end of the adjusting rod 137 away from the movable block 136 is fixedly connected to a fan-shaped plate 1310, and the fan-shaped plate 1310 is slidably connected to the inner wall of the three-way cavity plate 138. The bottom of the electrolytic cell body 1 is located directly below the anode chamber 9 and the cathode chamber 10, and a valve 5 is fixedly connected. The outer wall of the electrolytic cell body 1 is fixedly connected to a control panel 4, and the control panel 4 is electrically connected to the valve 5, the ultrasonic sensor 122, the propeller 123, the chlorine gas detector 131, the fan 133 and the electric telescopic rod 135.
[0045] The slots of the multi-slot hollow column 134 correspond to the shapes of the movable block 136, the material of the sector plate 1310 is rubber, and the cavity shape of the three-branch cavity plate 138 corresponds to the shape of the sector plate 1310;
[0046] Preferably: during the electrolysis process, the gas outlet pipes 3 on both sides are kept in a sealed state, and the chlorine concentration generated during the electrolysis of the sodium chlorate solution in the anode chamber 9 is monitored in real time by the chlorine detector 131. When the chlorine concentration in the anode chamber 9 reaches the set maximum threshold, the chlorine detector 131 transmits an over-limit signal to the control panel 4, and the control panel 4 controls the operation of the electric telescopic rod 135 to drive the movable block 136 to retract downward, and then, under the cooperation of each adjusting rod 137 and the rectangular hole 139, each sector plate 1310 can be driven to move closer to the inner wall of the three-way cavity plate 138, so that each sector plate 13 10 maintains a certain gap with the inner wall of the outlet pipe 3 so that the outlet pipe 3 remains unobstructed. At this time, the output end of the outlet pipe 3 is connected to the relevant collecting container, and the control panel 4 controls the operation of the fan 133 to pump the chlorine gas upward through the gas collecting hood 132, and pump the high-concentration chlorine gas into the container to avoid polluting the external environment, thereby finally completing the monitoring and adjustment of the chlorine concentration inside the anode chamber 9. While the electrolysis process maintains a sealed and stable operating environment, it can also be adjusted according to special circumstances to ensure the balance of the chlorine concentration in the anode chamber 9, avoid excessive chlorine molecules from contacting the anode plate 7 to cause corrosion to it, and extend its service life.
[0047] The above implementation works as follows:
[0048] The initialization steps are as follows:
[0049] The dissolved sodium chlorate solution is injected into the anode chamber 9 and the cathode chamber 10 in the electrolytic cell body 1, and the power supply is turned on so that the anode plate 7 and the cathode plate 8 are energized;
[0050] The working steps are as follows:
[0051] like Figure 1 - Figure 7As shown, the sodium chlorate solution undergoes electrolytic reaction in the cathode chamber 10 and the anode chamber 9 through the cathode plate 8 and the anode plate 7, and an ultrasonic sensor 122 is arranged in the middle of the diaphragm 11 to monitor the precipitated gas in the anode chamber 9 and the cathode chamber 10 in real time, and analyze its position and morphology. When uneven gas precipitation is detected and bubbles gather, the ultrasonic sensor 122 transmits the abnormal situation through an electrical signal, controls the rotation of the propellers 123 on both sides through the control panel 4, and transmits the rotational force through the pulley 124 and the connecting belt 125, so that the main bevel gears 126 connected to the diaphragm 11 on both sides rotate synchronously, and with the rotation of the main bevel gears 126 on both sides, the meshing and connected auxiliary bevel gears 127 are driven to rotate in the middle of the diaphragm 11. The transmission gear 128 fixedly connected to the secondary bevel gear 127 can rotate accordingly. With the auxiliary support of the guide rails 121 on both sides, the rotation of the transmission gear 128 can drive the meshing racks 129 on both sides to move closer to or away from each other in the horizontal direction, thereby driving the anode plate 7 and the cathode plate 8 to slide on the outer walls of the guide rails 121 on both sides. By adjusting the spacing between the anode plate 7 and the cathode plate 8, the heat distribution generated during the electrolysis process can be affected. The appropriate spacing can make the current pass through the electrolyte solution more evenly and reduce local overheating. Therefore, the heat in the electrolytic cell body 1 can be neutralized by adjusting the distance between the cathode plate 8 and the anode plate 7 to avoid the accumulation of hydrogen and chlorine bubbles in the cathode chamber 10 and the anode chamber 9. , which is conducive to the uniform precipitation of gas. According to the bubble aggregation state and position information detected by the ultrasonic sensor 122, after increasing the distance between the anode plate 7 and the cathode plate 8 to the maximum, the control panel 4 can be used to control the propellers 123 on both sides to stop rotating, thereby reducing the efficiency of the electrolysis of the sodium chlorate solution, so that the bubble precipitation rate is reduced, which is convenient for the uniform precipitation of gas. Correspondingly, when the electrolysis efficiency of the sodium chlorate solution is low, the distance between the anode plate 7 and the cathode plate 8 can be adjusted to be closer, and the electrolysis operation can be flexibly adjusted. At the same time, with the rotation of two of the main bevel gears 126, the other two main bevel gears 126 arranged on both sides of the inner wall of the electrolytic cell body 1 can also rotate with it, and drive the reciprocating screw rods 12 on both sides through the corresponding secondary bevel gears 127 meshing with them. 10 rotates inside the cathode chamber 10 and the anode chamber 9, and further, with the assistance of the limiting rods 1211 on both sides, it can drive the rollers 1212 on both sides that are threadedly connected to the outer wall of the reciprocating screw rod 1210 to move up and down, so as to clean the outer wall meshes of the nickel wire meshes 6 on both sides. During the electrolysis of the sodium chlorate solution, the chloride ions and the hydroxide ions therein will react during the electrolysis process to produce precipitates or bubbles, which will block the meshes of the nickel wire meshes 6 on both sides over time. The roller 1212 is arranged to reciprocate up and down on the outer wall of the nickel wire mesh 6 while adjusting the heat distribution during the electrolysis of the sodium chlorate solution, so that the meshes of the nickel wire mesh 6 can be cleaned regularly to ensure the patency of the meshes, and to ensure that the current passes through the entire electrolysis surface evenly.Ensuring effective contact between the solution and the electrode is beneficial to improving electrolysis efficiency and reducing energy loss;
[0052] like Figure 6 , Figure 8 - Fig.12 As shown, during the electrolysis process, the gas outlet pipes 3 on both sides are kept in a sealed state, and the chlorine concentration generated during the electrolysis of the sodium chlorate solution in the anode chamber 9 is monitored in real time by the chlorine detector 131. When the chlorine concentration in the anode chamber 9 reaches the set maximum threshold, the chlorine detector 131 transmits an over-limit signal to the control panel 4, and the control panel 4 controls the operation of the electric telescopic rod 135 to drive the movable block 136 to retract downward, and then, with the cooperation of each adjusting rod 137 and the rectangular hole 139, each sector plate 1310 can be driven to move closer to the inner wall of the three-way cavity plate 138, so that each sector plate 1310 can maintain a certain gap with the inner wall of the gas outlet pipe 3, so that the gas outlet pipe 3 remains unobstructed, and at this time, the output end of the gas outlet pipe 3 is connected to a related collection container (such as a gas cylinder or a gas collection tank). Then, at the same time, the control panel 4 controls the operation of the fan 133 to discharge the chlorine gas upward through the gas collecting hood 132, and the high-concentration chlorine is extracted and output into the container to avoid polluting the external environment, thereby finally completing the monitoring and adjustment of the chlorine concentration inside the anode chamber 9. While the electrolysis process maintains the sealed and stable operating environment, it can also be adjusted according to special circumstances to ensure the balance of the chlorine concentration in the anode chamber 9, avoid excessive chlorine molecules from contacting the anode plate 7 and causing corrosion to it, thereby extending its service life. Finally, after the electrolysis treatment, the sodium perchlorate solution is evaporated and concentrated to increase the concentration of the solution, and the concentrated solution is cooled to a certain temperature to precipitate and crystallize the sodium perchlorate, and the precipitated sodium perchlorate crystals are dried by air flow to remove residual moisture to obtain the final product, and finally the valve 5 is opened to obtain the prepared sodium perchlorate product.
