Description

Technical Field

[0001] This invention relates to the field of adsorbent recovery technology, specifically to a high-efficiency recovery device for adsorbent treatment. Background Technology

[0002] The widespread use of sulfur hexafluoride (SF6) insulation equipment in the power system has made the non-toxic and environmentally friendly treatment of SF6 adsorbents an issue that power companies cannot ignore. Current research on thermal regeneration technology for SF6 adsorbents indicates that to completely desorb the adsorbate, the adsorbent must be heated to 180–200 degrees Celsius for more than 2 hours, relying on thermal regeneration. However, due to the high greenhouse effect index of SF6, once released into the atmosphere, it will keep the Earth's temperature at a near-permanent high level. Therefore, to prevent global warming, SF6 needs to be strictly treated, and among the many treatment methods, the SF6 adsorbent method is the most suitable.

[0003] A Chinese invention patent publication (CN114682240A) discloses an environmentally friendly treatment device for sulfur hexafluoride (SF6) adsorbent. This invention includes a reactor for containing SF6 adsorbent and a stirrer for agitating the mixture containing the SF6 adsorbent within the reactor. While this invention improves the uniformity of the mixed solution containing SF6 adsorbent and enhances the recovery and treatment effect of the SF6 adsorbent, it only achieves the recovery and treatment of the SF6 adsorbent and cannot improve the safety performance of the recovery device. Furthermore, it cannot improve the mixing effect between the alkali and the solution, shorten the processing time, accelerate the generation of reaction products, or classify the stirring space of each stirring component, thus failing to improve the stirring efficiency. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a high-efficiency recovery device for adsorbent treatment, comprising a heating component having a heater that continuously provides high temperature;

[0005] The reaction section, used for adsorbing and recovering sulfur hexafluoride, has a double-hoop structure that is in direct contact with the heat source. The walls of the double-hoop structure have several hexagonal cavities spaced at equal intervals to retain some heat energy. The top of the double-hoop structure is flared, allowing the mixed solution to be distributed in two layers within the double-hoop structure. The flared design of the upper layer increases the solution pressure at the bottom of the double-hoop structure, simultaneously accelerating the mixing speed of the added alkali material to the bottom of the solution and improving the mixing effect between the alkali material and the solution. A thin-walled bottom cover is fixedly connected to the bottom of the double-hoop structure, and a sealing plate is installed on the top of the double-hoop structure. The bottom edge of the sealing plate is embedded in the upper port of the double-hoop structure, and a motor is fixedly installed on the top of the sealing plate. A drive wheel is assembled on the output end of the motor.

[0006] The discharge assembly is used to discharge the reaction products. The discharge assembly has a pump that provides suction force, and the pump has a tee pipe connected to the pump pipe for discharging the reaction products.

[0007] A stirring assembly for stirring a mixed solution includes a stirring tube for conveying reaction products, and a drive gear is positioned on the outer surface of the stirring tube. The stirring tube is rotatably mounted to a cover plate via a collar and extends into the inner cavity of a double-hoop body. A defoamer is fixedly connected to the stirring tube near the cover plate. A first stirring element and a second stirring element are installed on the outer surface of the stirring tube and below the defoamer for stirring the mixed solution. A motor drives the mixture through a drive wheel meshing with the drive gear.

[0008] Preferably, the top of the heater is fixedly connected to an upwardly extending hot cylinder, the outer wall of the hot cylinder is hollow, and a number of heat-conducting plates are connected at equal intervals on the inner wall surface of the outer wall to slow down the rate of heat dissipation.

[0009] Preferably, a plurality of heat-blocking cavities are equally spaced on one side of the inner wall surface where the hot cylinder body and the double hoop body are in contact, and a retaining ring is fixedly connected to the other side of the inner wall surface where the hot cylinder body and the double hoop body are in contact, and the bottom of the double hoop body is fitted into the hot cylinder body through the retaining ring.

[0010] Preferably, the top of the cover plate is fixedly connected to a No. 1 material pipe for introducing water, a No. 2 material pipe for introducing alkali material, and an adsorbent inlet pipe for introducing the crushed sulfur hexafluoride adsorbent. All three are spiral in shape. The spiral pipe design allows the material to accumulate in the spiral pipe for a short time when the corresponding reactants are added into the double hoop, thus preventing the leakage of harmful substances inside the double hoop and reducing the risk of workers directly contacting toxic substances.

[0011] Preferably, the outer surface of the three-way pipe is fixed with a connecting guide, and a hydraulic cylinder is fixedly connected to the top of the connecting guide. A disc frame is bolted to the top of the hydraulic cylinder, and a bolt is bolted to the bottom of the cover plate. The bottom of the three-way pipe is sealed with a first rotating connector. The first rotating connector is mounted on the cover plate by a support plate and bolts, and the bottom of the first rotating connector is inserted into the upper end of the stirring pipe, so that the stirring pipe can rotate between the first rotating connector and the second rotating connector, and ensure that the stirring pipe, with the cooperation of the auxiliary components, can seal and transport the reaction products.

[0012] Preferably, a folded connector is connected between the three-way pipe and the pump, allowing the three-way pipe and the pump's suction pipe to move vertically and vertically during the lifting of the stirring pipe by the hydraulic cylinder. This facilitates the sealing and opening of the expansion mask and the bottom of the double hoop. The folded connector is coated with an acid and alkali resistant coating to prevent the mixed solution from directly corroding the folded connector and causing liquid leakage, ensuring the safe use of the recovery device. Furthermore, a discharge pipe is connected to the side of the three-way pipe away from the second material pipe for discharging the reaction products. A pH meter is embedded in the upper port of the vertical section of the three-way pipe, and a detection rod is connected to its bottom to the inner bottom of the double hoop for detecting the pH value of the mixed solution.

[0013] Preferably, the first stirring component includes a wide-faced component, the surface of which is provided with an annular opening, a trapezoidal opening, and an oblique hole. A lower guide plate is fixedly connected to the surface of the wide-faced component at a position corresponding to the trapezoidal opening, for guiding the liquid downward.

[0014] Preferably, the upper and lower ends of the wide surface component are fixedly connected with tail rings, and the two sides of the wide surface component are symmetrically connected with elliptical rings, and a connecting rod is fixedly connected between the elliptical rings and the wide surface component.

[0015] Preferably, a second rotating connector is sleeved at the bottom of the stirring tube, and an auxiliary component is sleeved at the bottom of the second rotating connector. The auxiliary component is rotatably installed with the stirring tube through the second rotating connector, and the second stirring element is fixedly connected to the stirring tube in a fan shape.

[0016] Preferably, the auxiliary component includes a sleeve fitted at the bottom of the second rotating tube, with a balloon and a dilator fixedly connected to the bottom of the sleeve. The dilator is fixedly connected to the bottom of the balloon, and an annular semicircular plate is fixedly connected to the bottom of the dilator, which can fit tightly against the inner wall of the bottom cover. The surfaces of the balloon, the dilator, and the annular semicircular plate are all coated with an acid and alkali resistant coating.

[0017] This invention provides a high-efficiency recovery device for adsorbent treatment. It has the following beneficial effects:

[0018] I. This high-efficiency recovery device for adsorbent treatment, through a discharge pipe, a three-way pipe, a first rotary connector, a stirring pipe, a second rotary connector, a sleeve, a balloon, and a diffuser, is connected to establish a conveying pipeline for transporting reaction products. Utilizing the strong suction provided by the pump, the reaction products overcome gravity and are transported vertically upwards. This method reduces the amount of reaction products remaining in the traditional horizontal discharge pipe. Even if some reaction products adhere to the pipeline, they will eventually fall back into the double-hoop body under their own weight, reducing direct exposure of reaction products to the outside air and preventing byproducts from polluting the surrounding environment, thus improving the safety performance of the recovery device.

[0019] Second, this high-efficiency recovery device for adsorbent treatment uses a hexagonal cavity to retain some heat in the wall plate of the double hoop, avoiding stagnation in heat transfer between the hot cylinder and the double hoop. This gives the double hoop a certain degree of local heat preservation and heat retention capacity. Combined with the thin-walled bottom cover, it promotes the reaction rate of the hot cylinder with the mixed solution and alkali. The flared design at the top of the double hoop allows the mixed solution to be distributed in two layers within the inner cavity of the double hoop. The flared design of the upper layer results in a higher solution pressure at the bottom of the double hoop. At the same time, it can help accelerate the mixing speed of the added alkali to the bottom of the solution, improving the mixing effect between the alkali and the solution.

[0020] Third, this high-efficiency recovery device for adsorbent treatment, through its wide-faced components and various holes on its surface, can achieve different stirring effects on the mixed solution during rotation; the inclined guided stirring of the mixed solution through the annular opening and inclined holes makes the solution more uniformly mixed; and with the cooperation of the trapezoidal opening and the lower guide plate, the alkali material suspended above the double hoop and the adsorbent that has not been fully diffused can be quickly guided downwards, so that all substances can be uniformly mixed and fill the entire cavity of the double hoop, so that the reaction rate of the mixed solution can be accelerated under the high temperature promotion of the heater, thereby shortening the reaction time, accelerating the generation of reaction products, and shortening the processing time.

[0021] IV. This high-efficiency recovery device for adsorbent treatment, through the rotation of the first and second stirring elements following the stirring tube, can not only mix and stir the mixed solution, but also perform upper, middle and lower layer stirring of the mixed solution in the inner cavity of the double hoop according to the distribution of the mixed solution inside the double hoop, reducing the overall stirring area of ​​the stirring tube, dividing the stirring space of each stirring component in a graded manner, and improving stirring efficiency; by using a hydraulic cylinder to drive the expansion mask at the bottom of the stirring tube to adhere to and open with the bottom of the double hoop, the discharge of products after the reaction is completed is controlled, and a pH meter is used to measure the acidity and alkalinity of the solution before and after the reaction and during the reaction in real time.

[0022] V. This high-efficiency recovery device for adsorbent treatment expands the effective contact area between the double hoop and the heater through the hot cylinder, increasing the heating area of ​​the heater on the outside of the double hoop per unit time; it utilizes the heat-conducting plate to guide the heat energy in a tortuous manner and appropriately guide the heat to its corresponding heat-blocking cavity, so that the double hoop is heated evenly while slowing down the heat loss, thereby rapidly heating the mixed solution in the inner cavity of the double hoop, improving the reaction rate of the mixed solution and the alkali material, and shortening the reaction time.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0033] First embodiment, such as Figures 1-4 As shown, the present invention provides a technical solution: a high-efficiency recovery device for adsorbent treatment, including a heating component 1, which has a heater 101 that continuously provides high temperature; a heating cylinder 102 extending upward is fixedly connected to the top of the heater 101, the outer wall of the heating cylinder 102 is hollow, and a plurality of heat-conducting plates 103 are connected at equal intervals on the inner wall surface of the outer wall to slow down the heat dissipation rate; a plurality of heat-blocking cavities 104 are opened at equal intervals on one side of the inner wall surface of the heating cylinder 102 that is in contact with the double hoop 201, and a retaining ring 105 is fixedly connected to the other side of the inner wall surface of the heating cylinder 102 that is in contact with the double hoop 201, and the bottom of the double hoop 201 is fitted into the heating cylinder 102 through the retaining ring 105;

[0034] The reaction section 2 is used to adsorb and recover sulfur hexafluoride. The reaction section 2 has a double hoop 201 that is in direct contact with the heat source. The wall of the double hoop 201 has several hexagonal cavities 202 that are evenly spaced to retain some heat energy. The top of the double hoop 201 is designed to be flared. The bottom of the double hoop 201 is fixedly connected to a bottom cover 203 with a thin wall. The top of the double hoop 201 is sealed with a cover plate 204, and the bottom side of the cover plate 204 is embedded in the upper port of the double hoop 201. The top of the cover plate 204 is fixedly connected to a first feed pipe 205 for introducing water, a second feed pipe 206 for introducing alkali, and an adsorbent feed pipe 207 for introducing the crushed sulfur hexafluoride adsorbent. All three are spiral in shape.

[0035] In use, the effective contact area between the double hoop 201 and the heater 101 is increased by the heating cylinder 102, thereby expanding the heating area of ​​the double hoop 201 to the outside of the heater 101 per unit time. The heat-conducting plate 103 guides the heat energy in a tortuous manner and appropriately guides the heat to its corresponding heat-blocking cavity 104, so that the double hoop 201 is heated evenly while slowing down the loss of heat. This allows for rapid heating of the mixed solution in the inner cavity of the double hoop 201, improving the reaction rate between the mixed solution and the alkali and shortening the reaction time.

[0036] The hexagonal cavity 202 allows some heat to be retained in the wall of the double hoop 201, avoiding the obstruction of heat transfer between the hot cylinder 102 and the double hoop 201. This gives the double hoop 201 a certain local heat preservation and heat-locking capacity. Combined with the thin-walled bottom cover 203, this promotes the effect of the hot cylinder 102 on increasing the reaction rate of the mixed solution and alkali.

[0037] The flared design at the top of the double hoop 201 allows the mixed solution to be distributed in two layers within the cavity of the double hoop 201. The flared design of the upper layer increases the pressure of the solution at the bottom of the double hoop 201, and at the same time, it can help accelerate the mixing speed of the added alkali material to the bottom of the solution, thereby improving the mixing effect between the alkali material and the solution.

[0038] Second embodiment, such as Figures 4-6As shown, the discharge assembly 4 is used to discharge the reaction products. The discharge assembly 4 has a suction pump 401 that provides suction force, and a three-way pipe 402 for discharging the reaction products is connected to the suction pipe of the suction pump 401. A connecting guide 403 is fixedly attached to the outer surface of the three-way pipe 402, and a hydraulic cylinder 404 is fixedly connected to the top of the connecting guide 403. A disc bracket 405 is bolted to the top of the hydraulic cylinder 404, and a bolt is bolted to the bottom of the cover plate 204. A first rotating connector 406 is sealed to the bottom of the three-way pipe 402. The first rotating connector 406 is mounted on the cover plate 204 by a support plate and bolts. A rotary connector 406 is inserted into the upper end of the stirring tube 501 at its bottom; a folded connector is connected between the three-way pipe 402 and the pump 401, and the folded connector is coated with an acid and alkali resistant coating; and a discharge pipe is connected to the side of the three-way pipe 402 away from the second material pipe 206 for discharging the reaction products. A pH meter 7 is embedded in the upper port of the vertical part of the three-way pipe 402, and a detection rod is connected to the bottom of the two-hoop body 201 for detecting the pH value of the mixed solution. A motor 3 is fixedly installed on the top of the cover plate 204, and a drive wheel is assembled on the output end of the motor 3. The motor 3 is driven by meshing with the transmission gear 502 through the drive wheel.

[0039] In use, the wide surface part 5041 and the various holes on its surface can achieve different stirring effects on the mixed solution during rotation. The inclined guided stirring of the mixed solution through the annular opening 5042 and the inclined hole 5045 makes the solution more uniformly mixed. With the cooperation of the trapezoidal opening 5043 and the lower guide plate 5044, the alkali material suspended above the double hoop 201 and the adsorbent that has not been fully diffused can be quickly guided downwards. This allows the various substances to be uniformly mixed and fill the entire inner cavity of the double hoop 201. This facilitates the acceleration of the reaction rate of the mixed solution under the high temperature promotion effect of the heater 101, thereby shortening the reaction time, accelerating the generation of reaction products, and shortening the processing time.

[0040] The third embodiment, such as Figures 5-8As shown, the stirring assembly 5 is used to stir the mixed solution. The stirring assembly 5 has a stirring tube 501 for conveying reaction products, and a transmission gear 502 is positioned on the outer surface of the stirring tube 501. The stirring tube 501 is rotatably mounted to the cover plate 204 via a collar and extends into the inner cavity of the double-hoop body 201. A defoamer 503 is fixedly connected to the stirring tube 501 near the cover plate 204 to eliminate bubbles generated by the inclined hole 5045 during stirring in the solution. A first stirring element 504 and a second stirring element 505 are installed on the outer surface of the stirring tube 501 and below the defoamer 503 for mixing the solution located at the bottom of the double-hoop body 201. The first stirring element 504 includes a wide surface part 5041, the surface of which has an annular opening 5042, a trapezoidal opening 5043, and an inclined hole 5045. A lower guide plate 5044 is fixedly connected to the trapezoidal opening 5043 to guide the liquid downwards; a tail ring 5046 is fixedly connected to both the upper and lower ends of the wide surface part 5041, and elliptical rings 5047 are symmetrically connected to both sides of the wide surface part 5041. A connecting rod 5048 is fixedly connected between the elliptical ring 5047 and the wide surface part 5041 to enhance the connection strength between the elliptical ring 5047 and the wide surface part 5041; the tail ring 5046, elliptical ring 5047 and connecting rod 5048 rotate with the stirring tube 501, and the solution located in the middle of the double hoop body 201 can be directly mixed and stirred; a second rotating pipe 506 is sleeved at the bottom of the stirring tube 501, and an auxiliary component 6 is sleeved at the bottom of the second rotating pipe 506. The auxiliary component 6 is rotatably installed with the stirring tube 501 through the second rotating pipe 506, and the second stirring element 505 is fixedly connected to the stirring tube 501 in a fan shape;

[0041] The auxiliary component 6 includes a sleeve 601 fitted at the bottom of the second rotating tube 506. A balloon 602 and a dilator mask 603 are fixedly connected to the bottom of the sleeve 601. The dilator mask 603 is fixedly connected to the bottom of the balloon 602, and an annular semicircular plate 604 is fixedly connected to the bottom of the dilator mask 603. It can fit tightly against the inner wall of the bottom cover 203. The surfaces of the balloon 602, the dilator mask 603, and the annular semicircular plate 604 are all coated with an acid and alkali resistant coating.

[0042] In use, the first stirring element 504 and the second stirring element 505 rotate with the stirring tube 501, which can not only mix and stir the mixed solution, but also perform upper, middle and lower layer stirring of the mixed solution in the inner cavity of the double hoop 201 according to the distribution of the mixed solution inside the double hoop 201, reduce the overall stirring area of ​​the stirring tube 501, divide the stirring space of each stirring component into different levels, and improve the stirring efficiency.

[0043] The hydraulic cylinder 404 drives the expansion mask 603 at the bottom of the stirring tube 501 to adhere to and open the bottom of the double hoop 201, thereby controlling the discharge of the product after the reaction is completed, and using the pH meter 7 to measure the acidity and alkalinity of the solution before and after the reaction and during the reaction in real time.

[0044] Meanwhile, the above structures, including the discharge pipe, the three-way pipe 402, the first rotary connector 406, the stirring pipe 501, the second rotary connector 506, the sleeve 601, the balloon 602, and the expanding mask 603, are connected to form a conveying pipeline for transporting the reaction products. Under the strong suction provided by the pump 401, the reaction products overcome gravity and are transported vertically upward. In this way, the amount of reaction products remaining in the traditional horizontal discharge pipe is reduced. Even if some of the reaction products adhere to the pipeline, they will eventually fall back into the double hoop 201 under their own weight. This reduces the direct exposure of the reaction products to the outside air or prevents byproducts from polluting the surrounding environment, thus improving the safety performance of the recovery device.

[0045] By utilizing the ability of the balloon 602 to store a certain amount of air, when the expander mask 603 is attached to the bottom of the double hoop 201, the air pressure can push the reaction products away from the space covered by the expander mask 603, and isolate and preserve the residual reaction products inside the double hoop 201. This ensures that even if the residual reaction products, byproducts, or unreacted raw materials cannot be completely removed, they will not cause harm to the surrounding staff or the environment.

[0046] Working Principle: When using this device to recover sulfur hexafluoride adsorbent, the pulverized sulfur hexafluoride adsorbent is introduced into the reaction section 2 through the adsorbent inlet pipe 207; an appropriate amount of water is injected into the reaction section 2 through the first feed pipe 205; the motor is started to drive the stirring tube 501 to rotate within the double hoop body 201, and the solid-liquid mixture of sulfur hexafluoride adsorbent is stirred by the first stirring element 504 and the second stirring element 505. The pH value of the mixed solution is observed through the pH meter 7, and the amount of alkali to be added is calculated accordingly. Then, the flow through the second feed pipe 207 is opened. Add alkali material to the reaction section 2; start the heater 101 to heat the solid-liquid mixture containing sulfur hexafluoride adsorbent in the double hoop 201, and observe and control the temperature of the solid-liquid mixture at the same time. When the pH value no longer changes, it is considered that the chemical reaction is basically over. Stop the operation of the equipment, and lift the auxiliary component 6 at the bottom of the reaction section 2 upward through the hydraulic cylinder 404. Start the pump 401, and discharge the reaction product through the discharge pipe with the connection and cooperation between the sleeve 601, the balloon 602, the expanding mask 603, the stirring tube 501 and the three-way pipe 402.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
