Tar production with integrated tank area high-efficiency dehydration device

Abstract

This utility model relates to the technical field of dehydration devices, specifically a high-efficiency dehydration device for integrated tank farms in tar production. It includes a tank body, with a motor fixedly connected to the outside of the tank body. The output end of the motor passes through the tank body, and a spiral dehydration assembly is installed inside the tank body. The spiral dehydration assembly includes a rotating rod rotatably connected to the inside of the tank body, and the output end of the motor is fixedly connected to the rotating rod. Through the spiral dehydration assembly, during the tar guiding process, some water flows out through the leakage hole under the action of centrifugal force, thus achieving preliminary separation of tar and water. Furthermore, by strengthening the water agglomeration guiding component, the demulsifier can disrupt the stability of the emulsion in the tar, promoting water agglomeration. The guiding channel can guide the separated water to flow along the inner wall of the tank, allowing the water to more smoothly converge to the bottom of the tank for easy discharge, avoiding the static electricity generated by strong centrifugal force during tar dehydration.

[0001] This utility model relates to the field of dehydration equipment technology, and in particular to a high-efficiency dehydration device for integrated tank farms used in tar production. Background Technology

[0002] Moisture in tar dilutes effective components (such as pitch, phenols, naphthalene, etc.), leading to a decrease in tar viscosity, calorific value, and other indicators. After dehydration, the water content of tar usually needs to be controlled below 1% (some processes require below 0.5%) to meet the purity requirements of subsequent processing (such as the preparation of carbon materials, fuel oil, etc.).

[0003] Regarding the aforementioned technologies, the existing dehydration devices have the following drawbacks: during the centrifugal dehydration process, the tar may generate static electricity (the static voltage can reach thousands of volts) due to high-speed shearing, which may ignite the mixture of tar vapor and air. Therefore, this utility model provides a high-efficiency dehydration device for integrated tank farms in tar production. Utility Model Content

[0023] Example 1: Reference Figures 1-4The diagram illustrates a high-efficiency dehydration device for an integrated tank farm used in tar production. The device includes a tank body 1, which serves as the main support for the entire dehydration operation, providing a stable spatial environment for tar dehydration. A motor 6 is fixedly connected to the outside of the tank body 1, providing power to the entire device. Its output end passes through the tank body 1 to drive the spiral dehydration assembly inside the tank body 1. The spiral dehydration assembly includes a rotating rod 22 rotatably connected to the inside of the tank body 1. The output end of the motor 6 is fixedly connected to the rotating rod 22, which rotates under the drive of the motor 6. Spiral blades 16 are fixedly connected to the outside of the rotating rod 22. The spiral blades 16 are arranged in a spiral shape. When the rotating rod 22 rotates, the spiral blades 16 push the tar within the tank body 1, simultaneously using centrifugal force to separate the water from the tar. Multiple leakage holes 23 are provided on the outer side of the spiral blades 16, allowing the separated water to flow out through the holes, thus achieving preliminary separation of tar and water. A water agglomeration guiding component is installed inside the tank body 1. This component includes a guide channel 20 formed on the inner wall of the tank body 1, arranged in a spiral shape. The guide channel 20 guides the separated water to flow along the inner wall of the tank body 1, allowing the water to more smoothly converge to the bottom of the tank body 1 for easy discharge. A demulsifier storage tank 8 is fixedly connected to the outer side of the tank body 1. The demulsifier storage tank 8 stores demulsifier, which can disrupt the stability of the emulsion in the tar and promote water agglomeration. The output end of the demulsifier storage tank 8 passes through the tank body 1. A pressure pump is installed at the connection point between the demulsifier storage tank 8 and the annular distribution pipe 15. The pressure pump pressurizes and delivers the demulsifier in the demulsifier storage tank 8 to the annular distribution pipe 15. The output end of the demulsifier storage tank 8 is fixedly connected to a connected annular distribution pipe 15, which can evenly distribute the demulsifier. Multiple connected nozzles 21 are fixedly connected to the inner side of the annular distribution pipe 15. The nozzles 21 are inclined, allowing the demulsifier to be sprayed more comprehensively into the tar, ensuring thorough mixing between the demulsifier and tar, improving the demulsification effect, and accelerating water aggregation. A heating frame 2 is installed on the outer side of the tank body 1 to heat the tar inside the tank body 1. A heating chamber 17 is formed inside the heating frame 2, providing installation space for the heating pipe 19 and accommodating the heating medium. A heating tube 19 is installed inside the heating chamber 17. The heating tube 19 is arranged in a spiral shape, which increases the contact area with the heating medium, heats the tar in the tank 1 more evenly, reduces the viscosity of the tar, and makes it easier to separate the water in the tar. A hot water circulation pump 3 is fixedly connected to the outside of the heating frame 2. The hot water circulation pump 3 is used to drive the hot water to circulate in the heating system. A first output pipe 4 is fixedly connected to the output end of the hot water circulation pump 3. The first output pipe 4 passes through the heating frame 2, and the end of the first output pipe 4 away from the hot water circulation pump 3 is connected to the heating tube 19. The first output pipe 4 delivers the hot water output by the hot water circulation pump 3 to the heating tube 19.The hot water circulation pump 3 is fixedly connected to a return pipe 18. The return pipe 18 passes through the heating frame 2. The end of the return pipe 18 away from the hot water circulation pump 3 is connected to one end of the heating pipe 19. The return pipe 18 returns the hot water after passing through the heating pipe 19 to the hot water circulation pump 3, forming a hot water circulation system to ensure the continuous and stable operation of the heating process.

[0024] Example 2: Reference Figures 1-4 Based on the same concept as in Embodiment 1 above, this embodiment further proposes that a conveying pipe 7 is fixedly connected to the outside of the tank body 1. The conveying pipe 7 is used to convey the material inside the tank body 1 to the outside, realizing the material transfer function. The valve installed inside the conveying pipe 7 can control whether the material is conveyed and the conveying flow rate, ensuring that the material is conveyed as needed. A fixed cylinder 10 is fixedly connected to the outside of the tank body 1, providing a space carrier for material screening. A vibrating screen 14 is provided on the inner wall side of the fixed cylinder 10. The vibrating screen 14 is connected to the tank body 1 through a rubber connecting ring. The rubber connecting ring can ensure the connection stability between the vibrating screen 14 and the tank body 1, and can also buffer the vibration generated by the vibrating screen 14 during operation to avoid damage to the tank body 1. The vibrating screen 14 is used to screen the material and separate materials of different particle sizes. A vibrating motor 5 is fixedly connected to the outside of the fixed cylinder 10. The vibrating motor 5 drives the vibrating screen 14 inside the fixed cylinder 10 through a magnetic coupler. The vibrating motor 5 provides a power source for the vibrating screen 14, causing it to vibrate and improving screening efficiency. The magnetic coupler enables contactless transmission, reducing mechanical wear and extending the service life of the equipment. A SiC mechanical seal is provided between the magnetic coupler and the drive shaft of the vibrating motor. An outlet pipe 9, adapted to the vibrating screen 14, is provided on the outside of the fixed cylinder 10. The outlet pipe 9 is used to export the qualified material screened by the vibrating screen 14 for subsequent collection or processing. A conical cylinder 11 is fixedly connected to the end of the fixed cylinder 10 away from the tank 1. The conical cylinder 11 is used to collect and guide the material output from the fixed cylinder 10, allowing the material to flow more smoothly to the second outlet pipe 13. The second outlet pipe 13 is provided at the end of the conical cylinder 11 away from the fixed cylinder 10. The second outlet pipe 13 is used to transport the screened material to a designated location for final material output. A solenoid valve 12 is provided at the connection between the conical cylinder 11 and the second output pipe 13. The solenoid valve 12 can precisely control the timing and flow rate of the material entering the second output pipe 13 from the conical cylinder 11, ensuring the accuracy and controllability of the material output.

[0025] The working principle of this utility model is as follows: Tar is introduced into tank 1 through conveying pipe 7. Demulsifier is sprayed out through demulsifier storage tank 8 via annular distribution pipe 15 and multiple nozzles 21. The demulsifier reduces the interfacial tension between oil and water, making it easier for emulsified water droplets to coalesce. Control motor 6 drives rotating rod 22 and spiral blade 16 to rotate, guiding the tar. Some of the water contained in the tar slides along guide channel 20 to fixed cylinder 10 under the action of centrifugal force. Some water will be filtered out downward through leakage hole 23. The spiral blade 16 will increase the dehydration path of tar inside tank 1, making the dehydration of tar more thorough. Water enters conical cylinder 11 through vibrating screen 14. Vibrating screen 14 filters the tar again. Control vibrating motor 5 drives vibrating screen 14 to vibrate, further filtering the water in the tar. The dehydrated tar will slide out along outlet pipe 9.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
