Description

Technical Field

[0001] The invention relates to the technical field of needle coke production, in particular to a device for improving the raw material utilization rate of a needle coke solvent extraction pretreatment device. Background Art

[0002] Needle coke is a high-quality carbon raw material, mainly used in the manufacture of high-power and ultra-high-power graphite electrodes. It usually uses heavy aromatic hydrocarbons from petroleum or coal as raw materials, such as catalytic cracking oil slurry, ethylene tar, coal tar, etc. Before entering the production equipment, the raw materials need to be pretreated to remove solid impurities, moisture, metal ions, etc.

[0003] The light-phase asphalt recovery rate of existing needle coke solvent extraction pretreatment units generally ranges from 55% to 65%, while the heavy-phase asphalt recovery rate is approximately 35% to 45%. Heavy-phase asphalt, essentially a residue primarily composed of quinoline insolubles (QI), is inherently non-flowing and theoretically accounts for approximately 5% to 7% of the raw soft asphalt. Improving light-phase asphalt recovery is primarily due to two key bottlenecks: limited solvent separation technology and the tendency of heavy-phase asphalt to adhere to the equipment walls, causing blockage and disrupting continuous operation. These factors result in existing units still containing six to seven times the original weight of light-phase asphalt mixed with the separated heavy-phase asphalt. Reduced yield of light-phase asphalt, a feedstock for the delayed coking unit of coal-based needle coke systems, directly impacts the yield and performance of both green and cooked coke.

[0040] The working principle of the above embodiment is:

[0041] When the device is in use, the delivery connecting pipe 4 on the left side of the blanking body 1 will be connected to the raw material soft asphalt conveying equipment to ensure the raw material conveying effect of the device, and the delivery connecting pipe 4 on the right side of the blanking body 1 will convey the squeezed overflow liquid to other collection devices, and the oil replenishing pipe 6 will also be connected to the oil replenishing equipment to replenish the anthracene oil in the mixing spherical shell 3. The equipment for conveying and outputting raw materials and the supply equipment in this device are all existing mature technologies. This application highlights the innovative structure and does not elaborate too much on the existing technology.

[0042] Here, the soft asphalt transported to the blanking body 1 is pre-added with a mixed solvent. This ensures that after being separated from the original QI in the solvent system by the mixed solvent extraction in the blanking body 1, it overflows from the transport connecting pipe 4 on the upper right side of the blanking body and enters the light asphalt mixed liquid tank for storage, and then enters the above-mentioned collection device, ready to enter the light phase asphalt and solvent separation process on the lower side of the blanking body 1 for further separation of the solvent;

[0043] Due to the relationship of self-weight precipitation, the light phase asphalt in the falling vertical pipe 2 can be relatively compacted, thereby forming heavy phase asphalt. Under the mutual alternating action of the baffle plates 507 in the conversion component 5, the volume of the heavy phase asphalt entering the mixing spherical shell 3 is relatively fixed. Then, the fluid transportation performance of the heavy phase asphalt in the mixing spherical shell 3 can be guaranteed by the disturbance component 11. Then, anthracene oil is transported by the oil replenishment pipe 6. The anthracene oil replenishment line here is also a mature technology. This application will not go into too much detail. The separated heavy phase asphalt is re-dissolved by anthracene oil to restore its necessary fluidity, providing a strong guarantee for the necessary fluid transportation performance required for subsequent full utilization; it solves the problem of continuous operation after the breakthrough of the separation capacity of the solvent extraction pretreatment device of the needle coke device, the environmental protection problem of waste residue treatment, and at the same time improves the coal tar. The asphalt recovery rate of the device is as follows: the heavy phase asphalt enters the mixing spherical shell 3, and will be pumped out by the heavy mass circulation pump 9, and transported to the mixing spherical shell 3 by using the first L-shaped return pipe 1101 and the second L-shaped return pipe 1103, and the second L-shaped return pipe 1103 can transport the liquid to the annular pipe 1104, and then transport it to the lower side of the inner wall of the mixing spherical shell 3 through the nozzle 1106, so as to avoid the problem of sedimentation at the bottom of the mixing spherical shell 3, and a heavy oil to heavy oil mixed liquid tank is provided on the right side of the first L-shaped return pipe 1101, which can ensure the normal replenishment of anthracene oil. In this way, the simultaneous oil discharge of the oil replenishment pipe 6, the first L-shaped return pipe 1101 and the annular pipe 1104 is utilized to ensure the disturbance effect in the mixing spherical shell 3, and to provide a strong guarantee for the necessary fluid transport performance required for subsequent full utilization;

[0044] The conversion assembly 5 here uses the electric telescopic rod 511 as the main power output, driving the two blocking plates 507 to alternately insert into the drop vertical tube 2 and move. The electric telescopic rod 511 drives the rotating cylinder 502 on the pulling frame 512, which can ensure that the rotating cylinder 502 rotates around the two fixed plates 501. The rotation of the rotating cylinder 502 will use the ball head rod 503 to drive the connecting longitudinal column 505 on the pulling ring 504, thereby ensuring that the connecting longitudinal column 505 drives the blocking plate 507 to move, and the movement process of the blocking plate 507 will operate stably under the support of the support frame 509. Due to the rotation effect of the rotating cylinder 502, the As a result, the ball head rod 503 drives the blocking plates 507 to be staggeredly inserted into the drop vertical pipe 2. In this way, the upper blocking plate 507 moves away from the drop vertical pipe 2 while the lower blocking plate 507 moves closer to the drop vertical pipe 2. In this way, the heavy phase asphalt in the drop body 1 will fall to the position of the lower blocking plate 507. At this time, under the pushing action of the electric telescopic rod 511, the upper blocking plate 507 will move closer to the drop vertical pipe 2, while the lower blocking plate 507 will move away from the drop vertical pipe 2. Because the extension and retraction speed of the electric telescopic rod 511 is relatively fast, the control effect of the heavy phase asphalt will not be affected.

[0045] In the process of the upper baffle plate 507 moving close to the drop vertical pipe 2, the rotating cylinder 502 will drive the push inclined plate 1202 on the double groove block 1201 to move into the gas delivery shell 1210. The gas delivery shell 1210 can ensure the effect of transporting nitrogen to the inside through the gas delivery pipe 1227. When the push inclined plate 1202 is pushed to the position of the extrusion groove 1222, the top block 1208 on the push inclined plate 1202 will push the extrusion block 1226. In this way, the movement effect of the extrusion block 1226 cooperates with the piston pushing force of the first piston cylinder 1223 and the second piston cylinder 1224 to ensure that the thrust of the top block 1208 is converted into the thrust of the longitudinal push block 1215. The longitudinal push block 121 5 will use the connecting cross bar 1216 to drive the sealing cover block 1217 away from the partition plate 1211, and under the action of the movement of the sealing cover block 1217 away from the partition plate 1211, the clamping block 1220 on the sealing cover block 1217 is clamped with the clamping groove 1221 to ensure the temporary opening effect of the sealing cover block 1217. In the process of continuing to push the inclined plate 1202, it will be embedded in the storage circular groove 1204, and then the top block 1208 will move away from the squeezing block 1226. In this way, the gas delivery device pre-connected to the gas delivery pipe 1227 will deliver gas to the gas delivery shell 1210, so that the gas in the gas delivery shell 1210 will enter the drop vertical pipe 2 through the flow port 1212. The nitrogen gas delivered pushes the heavy phase asphalt that may be attached to the drop vertical pipe 2, avoiding the problem of heavy phase asphalt adhering to the surface of the drop vertical pipe 2. Due to the continuous blowing effect of the air supply pipe 1227, the sealing cover block 1217 will be subjected to the blowing extrusion force. When the force of the delivered nitrogen becomes greater and greater, until it is greater than the clamping force between the clamping block 1220 and the clamping groove 1221, the sealing cover block 1217 will re-clamp the partition plate 1211, thereby avoiding the problem of continuous output of nitrogen, and the gas delivered to the mixing ball shell 3 will be introduced into the exhaust gas treatment equipment through the L-shaped exhaust pipe 8, avoiding affecting the safety of the device during use. Here, the air supply pipe 1227 continuously blows to the gas shell 12 10, but the gas outlet of the flow port 1212 cannot be fully and timely discharged, which will cause the gas pressure in the gas delivery shell 1210 to increase. When the gas is continuously delivered, the thrust generated by the gas pressure in the gas delivery shell 1210 is greater than the friction and other obstacles at the clamping point of the clamping block 1220, and the sealing cover block 1217 will be pushed and then resealed. The clamping force of the clamping block 1220 and the clamping groove 1221 of this device is set to be relatively small, which is mainly reflected in the overall strength of the damping spring 1219 adopted in this application. The arc head setting of the clamping block 1220 of this device can greatly reduce the generation of friction, thereby ensuring the re-clamping effect of the sealing cover block 1217 during the process of delivering nitrogen;

[0046] When the inclined plate 1202 is pushed away from the gas transmission shell 1210, the top block 1208 here will rotate while contacting the extrusion block 1226. During the pushing process, the top block 1208 will be limited by the rotating groove 1206 and cannot rotate, thereby achieving the effect of pushing the extrusion block 1226. This device can use the conversion component 5 to link the conveying component 12 to transport the heavy phase asphalt in the falling vertical pipe 2, that is, to separate and disconnect the transportation, and cooperate with the disturbance component 11 in the mixing spherical shell 3 to dilute it again to achieve a usable flow state, which solves the problem of continuous operation of the solvent extraction pretreatment device of the needle coke device after the separation capacity is broken through, and the environmental protection problem of waste residue treatment, while improving the asphalt recovery rate of the coal tar device.

[0047] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply.

Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
