Description

Technical Field

[0001] This application relates to the field of phosphorus raw material storage technology, and in particular to an anti-oxidation and heat insulation device for phosphorus raw material storage tanks. Background Technology

[0002] In the development of the phosphorus chemical industry, the safe storage and quality assurance of phosphorus raw materials are key technologies. Phosphorus raw materials (such as yellow phosphorus and red phosphorus) are highly chemically reactive and easily react with oxygen in the air during storage, even spontaneously combusting. Furthermore, temperature fluctuations can exacerbate their chemical activity or cause changes in their physical state (such as melting or sublimation). Therefore, oxidation prevention and temperature control are crucial for the safe storage of phosphorus raw materials. Currently, phosphorus raw material storage tanks are used for storage. These tanks provide sealing and insulation, effectively isolating the phosphorus raw materials from oxygen and temperature.

[0003] In existing technologies, traditional phosphorus raw material storage tanks typically rely solely on the thermal resistance of the tank material itself for insulation. When the external ambient temperature fluctuates significantly, heat can easily be conducted through the tank to the interior, leading to unstable internal temperatures. When phosphorus raw materials generate heat due to chemical reactions or physical changes during storage, the tank cannot efficiently cool the phosphorus raw materials inside, posing a safety hazard. Moreover, traditional phosphorus raw material storage tanks mostly rely on sealed tanks to isolate oxygen. However, over time, when it is necessary to fill the storage environment inside the tank with inert gas (such as argon) for oxidation protection, the lack of efficient gas replacement makes it difficult to form a stable inert gas atmosphere, significantly reducing the oxidation protection effect.

[0004] Therefore, we propose an anti-oxidation and heat insulation device for phosphorus raw material storage tanks to solve the above problems. Utility Model Content

[0024] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] See Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides an anti-oxidation and heat insulation device for a phosphorus raw material storage tank, including a phosphorus raw material storage tank and a water-cooled cooling component and an argon injection anti-oxidation component installed on the phosphorus raw material storage tank. The phosphorus raw material storage tank includes an outer tank body 1 and an inner tank body 2. The inner tank body 2 is installed and fixed inside the outer tank body 1 by a support frame. A polyurethane heat insulation board 22 is fixedly installed on the inner wall of the outer tank body 1. The polyurethane heat insulation board 22 has good heat insulation performance and can effectively reduce the conduction of external heat into the inner tank body 2, which helps to maintain the temperature stability in the inner tank body 2 and improve the heat insulation effect. The inner tank body 2 is made of corrosion-resistant materials (such as 316L stainless steel or enamel steel), can directly contact the phosphorus raw material, and the inner surface of the inner tank body 2 is smooth and free of dead spots. To prevent oxidation of residual phosphorus raw materials, the outer tank 1 is made of carbon steel or aluminum alloy with an anti-corrosion coating (such as epoxy zinc-rich paint) on the outer surface to resist external environmental corrosion (rain, ultraviolet rays, etc.). The water-cooling component includes a water pump 3, a suction pipe 4, a main delivery pipe 5, multiple horizontal heat conduction pipes 6, multiple vertical heat conduction pipes 7, a return water main pipe 8, multiple horizontal heat conduction pipes 9, multiple vertical heat conduction pipes 10, and multiple heat conduction connecting pipes 11. The water pump 3 is fixedly installed on the left outer wall of the outer tank 1. The suction pipe 4 is fixedly connected to the suction end of the water pump 3. The main delivery pipe 5 is fixedly installed on the left outer wall of the inner tank 2. Both ends of the main delivery pipe 5 extend to the outside of the outer tank 1. One end of the main delivery pipe 5 is connected to the water pump. The discharge end of 3 is fixedly connected. Multiple transverse heat-conducting pipes 6 are fixedly connected to the main conveying pipe 5 and are evenly distributed. The right ends of multiple transverse heat-conducting pipes 6 extend into the inner tank 2. Multiple longitudinal heat-conducting pipes 7 are fixedly connected to the right ends of the corresponding transverse heat-conducting pipes 6. The return water main pipe 8 is fixedly installed on the right outer wall of the inner tank 2. Multiple transverse heat-conducting pipes 9 are fixedly connected to the return water main pipe 8 and are evenly distributed. The left ends of multiple transverse heat-conducting pipes 9 extend into the inner tank 2. Multiple longitudinal heat-conducting pipes 10 are fixedly connected to the left ends of the corresponding transverse heat-conducting pipes 9. The left ends of multiple heat-conducting connecting pipes 11 are fixedly connected to the corresponding longitudinal heat-conducting pipes 7. The right end of 11 is fixedly connected to the corresponding longitudinal heat-conducting pipe 10, and the multiple heat-conducting connecting pipes 11 are evenly distributed. The end of the suction pipe 4 away from the water pump 3 is fixedly connected to the output end of the external well water filter. The well pump pumps the well water to the well water filter to filter out impurities. By controlling the operation of the water pump 3, the filtered well water can flow sequentially through the suction pipe 4 and the main conveying pipe 5, along multiple transverse heat-conducting pipes 6, multiple longitudinal heat-conducting pipes 7, multiple heat-conducting connecting pipes 11, multiple longitudinal heat-conducting pipes 10 and multiple transverse heat-conducting pipes 9, and finally be transported away through the return water main pipe 8. This can comprehensively cover the inside of the inner tank 2 and quickly remove the heat generated during the storage of phosphorus raw materials.

[0026] In this embodiment, the water intake pipe 4, the main delivery pipe 5, multiple horizontal heat-conducting pipes 6, the longitudinal heat-conducting pipe 7, the return water main pipe 8, the second horizontal heat-conducting pipe 9, the second longitudinal heat-conducting pipe 10, multiple heat-conducting connecting pipes 11, the argon gas intake pipe 16, and the argon gas exhaust pipe 17 are all made of stainless steel pipes.

[0027] In this embodiment, an electromagnetic flow regulating valve 12 is fixedly installed on the main delivery pipe 5, and an electromagnetic flow regulating valve 23 is fixedly installed on the return water main pipe 8. Both the electromagnetic flow regulating valve 12 and the electromagnetic flow regulating valve 23 are located outside the outer tank 1. The installation of the electromagnetic flow regulating valve 12 and the electromagnetic flow regulating valve 23 can facilitate the adjustment of the well water flow rate and realize the control of the temperature of the inner tank 2, which helps to store the phosphorus raw material at a suitable temperature and avoid safety hazards and quality degradation caused by excessive temperature.

[0028] In this embodiment, the argon gas injection anti-oxidation component includes an argon gas delivery pump 15, an argon gas suction pipe 16, and an argon gas discharge pipe 17. The argon gas delivery pump 15 is fixedly installed on the bottom left side of the support plate 20. The argon gas suction pipe 16 is fixedly connected to the suction end of the argon gas delivery pump 15. The end of the main delivery pipe 5 away from the water pump 3 is fixedly connected to the discharge end of the argon gas delivery pump 15. The argon gas discharge pipe 17 is fixedly connected to one side of the main delivery pipe 5. The argon gas discharge pipe 17 is located below the electromagnetic check valve 14. One end of the argon gas discharge pipe 17... Extending into the inner tank 2, the argon gas intake pipe 16 is fixedly connected to the outlet port of the external argon gas storage tank. By controlling the operation of the argon gas delivery pump 15, argon gas is injected into the inner tank 2 through the argon gas intake pipe 16, the delivery main pipe 5, and the argon gas discharge pipe 17. As an inert gas, argon gas can effectively replace the air in the inner tank 2, forming an inert gas protective atmosphere, which greatly reduces the oxygen content in the inner tank 2. This can effectively isolate oxygen from contact with phosphorus raw materials, prevent the oxidation of phosphorus raw materials from the source, and ensure the quality and performance of phosphorus raw materials.

[0029] In this embodiment, an electromagnetic check valve 14 is fixedly installed on the main delivery pipe 5 between the outer tank 1 and the inner tank 2. The electromagnetic check valve 14 is located below the transverse heat conduction pipe 6. The electromagnetic check valve 14 serves two purposes: firstly, it prevents well water from entering the argon discharge pipe 17 and the argon delivery pump 15 during the cooling process inside the inner tank 2; secondly, it prevents argon from entering the multiple transverse heat conduction pipes 6 during the process of injecting argon into the inner tank 2 to reduce the oxygen content. This improves the reliability and stability of water cooling and argon injection for oxidation prevention.

[0030] In this embodiment, a support plate 20 is fixedly sleeved on the outer wall of the outer tank 1, and three support legs 21 arranged in an equal-spaced ring are fixedly installed at the bottom of the support plate 20 to stably support the phosphorus raw material storage tank.

[0031] In this embodiment, an electromagnetic check valve 2 18 is fixedly installed on the argon gas intake pipe 16, and an electromagnetic check valve 3 19 located below the argon gas discharge pipe 17 is fixedly installed on the main delivery pipe 5. The electromagnetic check valve 2 18 and the electromagnetic check valve 3 19 can prevent argon gas backflow, ensure that argon gas is continuously and stably injected into the inner tank 2, maintain the inert gas environment inside the tank, and ensure the anti-oxidation effect.

[0032] In this embodiment, an oxygen concentration sensor 23 and a temperature sensor 24 are fixedly installed on the top inner wall of the inner tank 2. The oxygen concentration sensor 23 can monitor the oxygen concentration inside the inner tank 2 in real time, and the temperature sensor 24 can monitor the temperature data inside the inner tank 2 in real time. The oxygen concentration sensor 23 and the temperature sensor 24 are electrically connected to an external display screen through wires. The monitored oxygen concentration value and temperature value can be displayed on the display screen for the on-duty personnel to check. Once the data is abnormal, corresponding measures can be taken in time to ensure the safety of the phosphorus raw material storage process. It should be noted that the way the oxygen concentration sensor 23 and the temperature sensor 24 are electrically connected to the external display screen is a mature technology in the field and has been fully disclosed, so it will not be described in detail here.

[0033] In this embodiment, a feed pipe 25 is fixedly installed on the top of the inner tank 2. The top end of the feed pipe 25 extends to the outside of the outer tank 1 and is fixedly fitted with a connecting flange 26. A sealing cover 27 is fixedly installed on the top of the connecting flange 26 by bolts. A discharge pipe 28 is fixedly installed at the center of the bottom of the inner tank 2. The bottom end of the discharge pipe 28 extends to the outside of the outer tank 1 and is fixedly fitted with a connecting flange 29. A sealing cover 30 is fixedly installed on the bottom of the connecting flange 29 by bolts, which facilitates the feeding and discharging of phosphorus raw materials.

[0034] In this embodiment, a pressure relief pipe 31 is fixedly installed on the top of the outer tank 1, and an electromagnetic pressure relief valve 32 is fixedly installed on the pressure relief pipe 31. The bottom end of the pressure relief pipe 31 extends into the inner tank 2. The setting of the pressure relief pipe 31 and the electromagnetic pressure relief valve 32 can timely depressurize the inner tank 2 during the injection of argon gas into the inner tank 2. On the one hand, it avoids excessive pressure inside the inner tank 2, thereby ensuring the safe operation of the device. On the other hand, the argon and oxygen mixture in the inner tank 2 can be discharged, thereby achieving efficient reduction of oxygen content inside the inner tank 2. It should be noted that the end of the pressure relief pipe 31 away from the outer tank 1 is fixedly connected to the gas inlet port of the external gas recovery tank. The argon and oxygen mixture discharged from the pressure relief pipe 31 can be temporarily stored in the gas recovery tank for subsequent separation and reuse.

[0035] With the above structure, the phosphorus raw material storage tank anti-oxidation and heat insulation device provided in this application can be used by using a wrench to remove multiple screws on the sealing cover plate 27, and then the phosphorus raw material can be poured into the inner tank 2 from the feed pipe 25. Then, the sealing cover plate 27 can be tightened and fixed on the connecting flange 26 with a wrench to store the phosphorus raw material. During the storage of phosphorus raw material, the polyurethane heat insulation plate 22 set on the inner wall of the outer tank 1 can play a good heat insulation role, which can effectively reduce the conduction of external heat into the inner tank 2, and help maintain the temperature stability in the inner tank 2. By turning on the oxygen concentration sensor 23 and the temperature sensor 24, the oxygen concentration sensor 23 can monitor the oxygen concentration inside the inner tank 2 in real time, and the temperature sensor 24 can monitor the temperature data inside the inner tank 2 in real time.

[0036] When cooling of the phosphorus raw material inside the inner tank 2 is required, the water pump 3 is started, and the electromagnetic flow regulating valve 12 and electromagnetic flow regulating valve 13 are opened, ensuring that the electromagnetic check valve 14 is closed. Filtered well water is drawn into the main delivery pipe 5 through the suction pipe 4. The well water in the main delivery pipe 5 flows into multiple longitudinal heat-conducting pipes 7 along multiple equally spaced transverse heat-conducting pipes 6, then is transversely transferred to multiple longitudinal heat-conducting pipes 10 through multiple heat-conducting connecting pipes 11, and finally converges into the return water main pipe 8 through multiple transverse heat-conducting pipes 9 and is transported away. During this process... The circulation path of the well water can fully cover the interior of the inner tank 2, and can quickly and efficiently remove the heat generated during the storage of phosphorus raw materials through heat exchange. At the same time, by controlling the opening of electromagnetic flow regulating valve 12 and electromagnetic flow regulating valve 23, the flow rate of the well water can be flexibly adjusted according to the actual temperature requirements in the inner tank 2, making it easier to control the temperature of the inner tank 2 and avoid safety hazards or quality degradation of phosphorus raw materials due to excessive temperature. When it is not necessary to cool down the phosphorus raw materials inside the inner tank 2, the water pump 3 is stopped and electromagnetic flow regulating valve 12 and electromagnetic flow regulating valve 23 are closed.

[0037] When argon needs to be injected into the inner tank 2 to prevent oxidation of the phosphorus raw material, the argon delivery pump 15 is started, and the electromagnetic check valves 18 and 19 are opened, ensuring that the electromagnetic check valve 14 is closed. Argon from the external argon storage tank enters the argon delivery pump 15 through the argon intake pipe 16, and then is injected into the inner tank 2 through the main delivery pipe 5 and the argon discharge pipe 17. As an inert gas, argon is denser than air and will quickly sink after injection. By opening the electromagnetic pressure relief valve 32, the inner tank 2 can be allowed to release pressure. Argon and oxygen mixture in tank 2 is discharged from pressure relief pipe 31, thereby replacing the air in inner tank 2 and forming an inert gas protective atmosphere. This significantly reduces the oxygen content in inner tank 2, thus isolating oxygen from contact with phosphorus raw materials at the source, preventing oxidation of phosphorus raw materials, and ensuring the quality and performance of phosphorus raw materials. When an appropriate amount of argon is injected into inner tank 2 to make the argon concentration reach the standard value, the argon delivery pump 15 is stopped, and electromagnetic check valve 18 and electromagnetic check valve 19 are closed.

[0038] When it is necessary to discharge phosphorus raw materials, use a wrench to remove the multiple screws on the sealing cover plate 230, and the phosphorus raw materials in the inner tank 2 can be discharged from the discharge pipe.
