Description

Technical Field

[0001] This utility model is a crude anthracene distillation and separation device, belonging to the field of crude anthracene distillation and separation. Background Technology

[0002] Currently, the main products of anthracene oil refining are refined anthracene and refined carbazole. The main physical separation methods include solvent extraction, solvent extraction-distillation, distillation, solvent extraction-distillation-sublimation, crystallization-washing-distillation, etc.

[0003] The most representative distillation method involves flash evaporation of anthracene oil and a mixture of crude anthracene to separate anthracene-rich oil. The anthracene-rich oil is then mixed with a solvent and fed into a crystallizer, where it is cooled and crystallized to separate phenanthrene oil. The phenanthrene-free anthracene-rich oil is then sent to a distillation column for further distillation. Fine anthracene and fine carbazole fractions are collected from the side stream, ultimately achieving the crude anthracene distillation separation technology.

[0004] Existing distillation columns, such as the Chinese utility model patent with application number 202422404409.1 entitled "A Distillation Column for Heat Recovery", describe how cold water from the outside is heated by the heat generated by the distillation column to ultimately achieve energy recovery. The drain pipe on the recovery tank is opened periodically to discharge the hot water that has absorbed the energy for reuse.

[0005] However, the energy recovery described in this patent enables the heating of cold water and the utilization of the discharged hot water, but users are unaware of the temperature range of the discharged hot water.

[0006] In some subsequent scenarios where hot water is needed, the temperature of the hot water does not meet the usage requirements, thus reducing the demand for hot water and consequently reducing energy recovery efficiency. Therefore, this invention proposes a crude anthracene distillation and separation device that can detect the temperature of energy recovery. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a crude anthracene distillation and separation device.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0009] A crude anthracene distillation and separation device includes a distillation column body. An insulation box is fixedly fitted on the outer wall of the bottom of the distillation column body, forming a heating space between the inner wall of the insulation box and the outer wall of the distillation column body. A circulation conveying assembly is provided on one side of the distillation column body. The circulation conveying assembly includes a setting box. A water inlet pipe with a sealing plug and a drain pipe with a valve are provided at the top of the setting box. A circulation adsorption assembly is provided on one side of the setting box. The setting box and the insulation box are connected through the circulation adsorption assembly. A docking pipe is provided on one side of the setting box. A detection probe of a temperature detector is inserted through the docking pipe. The temperature detector also has a temperature display screen. The detection probe penetrates into the distillation column body.

[0010] Furthermore, the circulating adsorption assembly includes a water pump with a suction pipe and an outlet pipe.

[0011] Furthermore, the water suction pipe is connected to the connecting pipe one on the setting box, the water outlet pipe is connected to the connecting pipe two on the insulation box, and a connecting pipe three is also provided between the setting box and the insulation box.

[0012] Furthermore, one end of the connecting pipe three is inserted into the top of the installation box, and multiple water distribution pipes are provided at the insertion end of the connecting pipe three.

[0013] Furthermore, a conical copper heat exchange box is installed at the top of the box, and a pipe is installed at the bottom of the copper heat exchange box. The other end of the connecting pipe is connected to an annular pipe located at the top of the insulated box, and atomizing nozzles are evenly arranged at the bottom of the annular pipe.

[0014] Furthermore, an integrated sealing tube 1 is fixedly installed on the outside of the temperature detector, and a sealing tube 2 is fixedly installed on the inside of the sealing tube 1. Sealing rings are attached to the inside of both the sealing tube 2 and the sealing tube 1.

[0015] Furthermore, a sealing tube three is fixedly provided on the outer side of the docking tube, and a secondary sealing ring is attached to the inner side of the sealing tube three. The docking tube is inserted into the sealing tube two, the sealing tube two is inserted into the sealing tube three, and the sealing tube three is inserted into the sealing tube one.

[0016] Furthermore, multiple arc-shaped mounting plates are fixedly provided on the outer surface of the sealing tube, and corresponding threaded insertion holes are opened on the arc-shaped mounting plates and the sealing tube.

[0017] A drive motor is fixedly installed at the top of the set box. The output end of the drive motor is connected to a drive rod located inside the set box. The drive rod passes through the copper heat exchange box, and a stirring plate is provided on the bottom outer surface of the drive rod.

[0018] The beneficial effects of this utility model are:

[0019] By setting up the set box, the circulating adsorption component circulates and adsorbs the water inside the set box, and then draws the adsorbed water into the heat preservation box. The low-temperature clean water is discharged into the heating space, forming a dense water mist inside the heat preservation box. The water mist directly contacts the inner wall of the heat preservation box and absorbs the heat conducted from the distillation column body to the heating space, thus absorbing the heat radiated into the space inside the heat preservation box.

[0020] The water that has absorbed heat can then be discharged back into the set tank, where it will be used in conjunction with the circulating adsorption components to absorb and heat the water, thus achieving circulating heating. The drain pipe allows the heated water to be discharged for use.

[0021] The temperature detector probe is located inside the set-top box to monitor the water inside in real time, ensuring that water of the appropriate temperature is discharged for use. The temperature of the hot water used subsequently is not consistent, and the temperature of the hot water can be detected. The final discharged hot water temperature is diversified to meet the needs of hot water temperature use in different scenarios. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-5 This utility model provides a crude anthracene distillation separation device, including a distillation column body 1. A heat preservation box 2 is fixedly sleeved on the outer wall of the bottom of the distillation column body 1. A heating space is formed between the inner wall of the heat preservation box 2 and the outer wall of the distillation column body 1. A circulation conveying assembly is provided on one side of the distillation column body 1. The circulation conveying assembly includes a setting box 3. A water inlet pipe 4 with a sealing plug and a drain pipe 5 with a valve are provided at the top of the setting box 3. A circulation adsorption assembly is provided on one side of the setting box 3. The setting box 3 and the heat preservation box 2 are connected through the circulation adsorption assembly. A docking pipe 6 is provided on one side of the setting box 3. A detection probe 8 of a temperature detector 7 is inserted through the docking pipe 6. The temperature detector 7 also has a temperature display screen 9. The detection probe 8 is inserted into the distillation column body 1.

[0032] See Figure 1-3The circulating adsorption assembly includes a water pump 10, which has a suction pipe 11 and an outlet pipe. The suction pipe 11 is connected to a connecting pipe 12 on the housing 3, and the outlet pipe is connected to a connecting pipe 13 on the insulation box 2. A connecting pipe 14 is also provided between the housing 3 and the insulation box 2. One end of the connecting pipe 14 passes through the top of the housing 3, and multiple branch pipes 15 are provided at the end of the connecting pipe 14. A conical copper heat exchange box 16 is also provided at the top of the housing 3, and a row of pipes is provided at the bottom of the copper heat exchange box 16, which is connected to... The other end of pipe 14 is connected to an annular pipe 17 located at the top of the insulation box 2. Atomizing nozzles are evenly arranged at the bottom of the annular pipe 17. The even distribution of atomizing nozzles allows for a sufficiently dense water mist inside the insulation box 2, which efficiently absorbs the heat conducted from the distillation column body 1 to the insulation box 2. The water distribution pipe 15 evenly disperses the hot water discharged into the insulation box 3, allowing the water that has absorbed heat to be dispersed through the water distribution pipe and contact the inner wall of the copper heat exchange box 16, thereby increasing the contact area and improving the heat exchange efficiency.

[0033] See Figure 4-5 An integrated sealing tube 18 is fixedly installed on the outer side of the temperature detector 7. A sealing tube 29 is fixedly installed on the inner side of the sealing tube 18. Sealing rings 20 are attached to the inner sides of both the sealing tube 29 and the sealing tube 18. A sealing tube 31 is fixedly installed on the outer side of the connecting tube 6. A secondary sealing ring 22 is attached to the inner side of the sealing tube 31. The connecting tube 6 is inserted into the sealing tube 29, the sealing tube 29 is inserted into the sealing tube 31, and the sealing tube 31 is inserted into the sealing tube 18. Multiple arc-shaped mounting plates 23 are fixedly installed on the outer surface of the sealing tube 18. Corresponding threaded insertion holes 24 are opened on the arc-shaped mounting plates 23 and the sealing tube 31.

[0034] See Figure 2 and Figure 6 A drive motor 25 is fixedly installed at the top of the setting box 3. The output end of the drive motor 25 is connected to a drive rod 26 located inside the setting box 3. The drive rod 26 passes through the copper heat exchange box 16, and a stirring plate 27 is provided on the bottom outer surface of the drive rod 26. The drive motor 25 drives the stirring plate 27 on the drive rod 26 to rotate. The stirring plate 27 is located at the bottom of the setting box 3. Because the generated hot water eventually gathers at the bottom of the setting box 3, and the water that has absorbed heat comes into contact with the inner wall of the copper heat exchange box 16 before being discharged to the bottom of the setting box 3, the temperature detection probe is also located at the bottom of the setting box 3. As the drive rod 26 and the stirring plate 27 slowly rotate, the water at the bottom of the setting box 3 is divided into an upper layer, a middle layer, and a bottom layer. The hot water first comes into contact with the upper layer of water at the bottom of the setting box 3. Therefore, the water in the middle and bottom layers has a certain temperature difference with the water in the upper layer. With the stirring, the water at the bottom of the setting box 3 is mixed, which ensures that the temperature difference of the water at the bottom is reduced, so that the temperature detected by the probe is more accurate.

[0035] During installation, the connecting pipe 6 is inserted into the sealing pipe 2 19, which in turn is inserted into the sealing pipe 3 21, and the sealing pipe 3 21 is inserted into the sealing pipe 1 18, achieving a multi-layered direct insertion effect. The sealing ring 20 and the secondary sealing ring 22 ensure that the outer surface of the pipe is wrapped by the corresponding sealing ring 20 and secondary sealing ring 22, achieving a multi-layered sealing connection. Subsequently, screws are inserted into the threaded insertion hole 24 to fix the temperature detector 7, thus installing it. If the temperature detector 7 is damaged, it can be disassembled for repair and replacement. It should be noted that the water pump 10 also has a suction pipe 11 and an outlet pipe, which can also be installed using this sealing connection method, ensuring that the water pump 10 can be returned to the factory for repair or replacement.

[0036] In use, by setting up box 3, the circulating adsorption component circulates and adsorbs the water inside box 3, drawing the adsorbed water into the insulation box 2. The cooler water is then discharged into the heating space, forming a dense water mist inside the insulation box 2. This water mist directly contacts the inner wall of the insulation box 2, absorbing the heat conducted from the distillation column body 1 into the heating space. Therefore, it absorbs the heat radiated into the space inside the insulation box 2. The water that has absorbed heat can then be discharged back into box 3, where it continues to absorb and heat the water in conjunction with the circulating adsorption component, thus achieving cyclic heating. The drainage pipe 5 is also installed... The heated water is then discharged for use. The temperature detector 7, with its detection probe 8 located inside the set box 3, monitors the water inside the set box 3 in real time to ensure that water at the appropriate temperature is discharged for use. The temperature of the hot water used later is inconsistent and can be detected. The final discharged hot water temperature is diverse and suitable for the hot water temperature requirements in different scenarios. The insulation box 2 is an existing box, except that the insulation box 2 described in the utility model is circular. The temperature detector 7 is an existing temperature detection device, which works in conjunction with the temperature display screen 9 to effectively detect the hot water temperature value.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
