TECHNICAL FIELD

[0001] The present application relates to the technical field of organic matter purification, and in particular to a C10 crude aromatic hydrocarbon rectification device and method thereof. BACKGROUND

[0002] C10 aromatic hydrocarbon mainly refers to aromatic hydrocarbon fractions containing ten carbon atoms obtained by catalytic reforming and ethylene cracking; wherein there are mainly quadricylene, paratetramethylbenzene, tetramethylbenzene, methylpropylbenzene, butylbenzene, diethylbenzene, methylindene, naphthalene, etc.; when refining C10 crude aromatic hydrocarbon, it needs to be treated by distillation, and impurities with large boiling point difference are removed by their different boiling points, so as to improve the rectification purity of C10 aromatic hydrocarbon.

[0003] But in actual use, it is found that the steam for distillation needs to be cooled to obtain the required product. Generally, cold water is introduced into the outer wall of the steam conveying pipe to achieve the purpose of liquefaction. However, when the gas flow rate in the internal conveying pipe is fast, the steam conveying pipe needs to be lengthened, so that the heat transfer time is long, and the liquefaction purpose is achieved. However, the length of the steam conveying pipe occupies a large amount of space, making the operation space of the workers smaller and the operation less convenient. SUMMARY

[0018] As a preferred embodiment of the C10 crude aromatics distillation apparatus and method of the present invention, a pair of connecting blocks are fixedly provided on the side wall of the gear shaft, and a baffle is fixedly provided at the end of the pair of connecting blocks, with the bottom of the baffle fitting into the connecting cavity. A torsion spring is snapped onto the surface of the gear shaft, and the torsion spring is in a rotating state.

[0019] As a preferred embodiment of the C10 crude aromatics distillation apparatus and method described in this invention, the method of using the C10 crude aromatics distillation apparatus comprises the following steps:

[0020] Step 1: First, the raw material is fed into the distillation cavity inside the distillation tank through the feed pipe. Then, the end cap of the distillation tank and the distillation tank are placed together and installed with locking bolts to ensure the sealing of the distillation tank. Then, the heating resistance wire is activated to perform the distillation operation on the raw material inside. The distilled liquid is discharged out through the cooling pipe.

[0021] Step 2: Start the drive motor. The drive motor will drive the turntable at the bottom of the rotating shaft to start rotating. The rotation of the turntable will cause the stirring rod at the bottom to start rotating. The stirring rod can mix the raw materials and reduce the occurrence of scorching at the bottom during the distillation process.

[0022] Step 3: The rotation of the turntable causes the position of the limiting slide groove on the surface to change, thereby causing the limiting slider and the push rod on the surface to move intermittently left and right. When the push rod moves to the left, it causes the sealing plate to move towards the baffle position. At this time, the baffle is in a self-locking state, that is, the space between the sealing plate and the baffle becomes smaller, thereby achieving the purpose of increasing the gas pressure. At this time, the cooling cavity on the outer wall is connected to ice water, which turns the gas into liquid by cooling and depressurizing, thus facilitating the later collection.

[0023] Step 4: During the movement of the sealing plate, the push rod and connecting plate of the synchronous rod on the surface begin to move inward. The movement of the connecting plate will drive the guide protrusion to slide along the third slide groove, move through the second slide groove to the first slide groove, and drive the insert plate connected to the guide protrusion to move upward. This will drive the positioning rack connected at the end to move upward, causing the positioning rack and the drive gear to separate, thereby releasing the self-locking state of the baffle. The baffle is opened by the internal pressure, thereby draining the internal liquid, and can be resealed by the internal torsion spring.

[0024] Step 5: The discharged liquid flows into the collection box through the guide plate. Observe the internal condition through the tempered glass. Open the sealed door with the handle to easily remove the collection box.

[0025] The beneficial effects of this invention are as follows: By incorporating an auxiliary unit, the drive motor inside the auxiliary unit rotates the stirring rod of the stirring assembly, thereby achieving the purpose of mixing the liquid and preventing it from scorching. During the stirring process, the push rod moves, pushing the sealing plate to the left, thus compressing the steam inside the cooling pipe and ensuring that all the steam is liquefied. After being compressed to a certain extent, the guide protrusion moves along the first slide groove, thereby unlocking the self-locking device of the baffle, opening the baffle, and discharging the liquefied product. The cooling and pressurization methods improve the liquefaction efficiency, ensuring that the equipment does not need to be large, occupies little space, and has a higher product productivity during the liquefaction operation.

[0046] By incorporating an auxiliary unit, the drive motor within the auxiliary unit rotates the stirring rod of the stirring assembly, thus mixing the liquid and preventing it from scorching. During the stirring process, the push rod moves, pushing the sealing plate to the left, compressing the steam inside the cooling pipe and ensuring complete liquefaction. Once compressed to a certain extent, the guide protrusion moves along the first slide groove, unlocking the self-locking device of the baffle and opening it to discharge the liquefied product.

Then, the end cap 1011 and the distillation tank 101 are placed together and installed with locking bolts 1013 to ensure the sealing of the distillation tank 101. The heating resistance wire 1041 is then activated to perform distillation on the raw material inside. The distilled liquid is discharged outward through the cooling pipe 106, while the waste residue is discharged outward through the discharge port 103 equipped with an electronic valve.

A connecting cavity 1062 is provided at the center of the cooling pipe 106, which is interconnected with the distillation cavity 1014 inside the distillation tank 101 and the internal chamber of the storage box 107. Water is supplied through the water outlet pipe 1063 and the water inlet pipe 1064, ensuring that there is flowing cold water inside the cooling cavity 1061, which can condense and liquefy high-pressure steam.

[0050] Reference Figure 1 and Figure 7The storage box 107 has an observation window frame 1071 on its surface, and a tempered glass 1072 is embedded inside the observation window frame 1071.

[0051] Example 2

[0052] This embodiment differs from the first embodiment in that:

[0053] Reference Figure 2 and Figure 3 Specifically, a drive motor 201 is fixedly installed on the surface of the end cap 1011 of the distillation tank. A rotating shaft 2011 is connected to the output end of the drive motor 2011, and a turntable 2012 is fixedly installed at the end of the rotating shaft 2011. A limiting groove 2022 is formed on the surface of the turntable 2012. The limiting groove 2022 is cam-shaped. A limiting slider 2021 is slidably installed on the surface of the limiting groove 2022. A push rod 202 is connected to the surface of the limiting slider 2021. A cross bracket 2023 is movably installed on the side wall of the push rod 202. The cross bracket 2023 is fixedly installed on the inner wall of the connecting cavity 1062. A notch 2025 is provided at the top of the connecting cavity 1062. The notch 2025 does not contact the sealing plate 2024. A sliding opening 2026 is provided on the side wall of the notch 2025. The sliding opening 2026 is connected to the distillation cavity 1014. The rotation of turntable 2012 causes the position of the limiting slide groove 2022 on the surface to change, thereby causing the limiting slider 2021 and the push rod 202 on the surface to move intermittently left and right, while the sealing plate begins to move at the same time.

[0054] Reference Figure 4 and Figure 6A vertical rod 203 is fixedly installed on the surface of the top rod 202, and a synchronizing rod 2031 is horizontally installed on the surface of the vertical rod 203. A pair of push rods 2032 are installed at the end of the synchronizing rod 2031. The end of the push rod 2032 is movably inserted into the installation cavity 1065 opened inside the cooling pipe 106. A connecting plate 204 is installed at the end of the push rod 2032. A first sliding groove 2041, a second sliding groove 2042 and a third sliding groove 2043 are sequentially opened on the surface of the connecting plate 204. The first sliding groove 2041, the second sliding groove 2042 and the third sliding groove 2043 are connected end to end. The second sliding groove 2042 is an inclined sliding groove, and the first sliding groove 2041 and the third sliding groove 2043 are horizontal sliding grooves. The third slide groove 2043 has a guide protrusion 205 that slides inside. A plate 2051 is fixedly installed at the bottom of the guide protrusion 205. The plate 2051 is movably installed through the side wall of the connecting cavity 1062. A positioning rack 206 is fixedly installed at the end of the plate 2051. A drive gear 2061 is meshed inside the positioning rack 206. A gear shaft 2062 is installed at the center of the drive gear 2061. Both ends of the gear shaft 2062 are movably engaged with the inner wall of the connecting cavity 1062. A spring rod 2052 is installed at the top of the plate 2051. The side wall of the spring rod 2052 is fixed inside the mounting cavity 1065. During the movement of the sealing plate 2024, the push rod 2032 and the connecting plate 204, which are lifted by the synchronous rod 2031 on the surface, begin to move inward. The movement of the connecting plate 204 will cause the guide protrusion 205 to slide along the third slide groove 2043, move to the first slide groove 2041 through the second slide groove 2042, and drive the insert plate 2051 connected to the guide protrusion 205 to move upward, thereby driving the positioning rack 206 connected at the end to move upward, so that the positioning rack 206 and the drive gear 2061 are separated, thereby releasing the self-locking rotation state of the baffle 2071.

[0055] Reference Figure 4 and Figure 5 A pair of connecting blocks 207 are fixedly installed on the side wall of the gear shaft 2062. A baffle 2071 is fixedly installed at the end of the pair of connecting blocks 207, and the bottom of the baffle 2071 fits against the connecting cavity 1062. A torsion spring 2063 is snapped onto the surface of the gear shaft 2062, and the torsion spring 2063 is in a rotating state. The baffle 2071 opens under the influence of internal pressure, thereby discharging the internal liquid, and can be resealed by the internal torsion spring 2063.

[0056] This invention also discloses a method for using a C10 crude aromatics distillation apparatus, the steps of which are as follows:

[0057] Step 1: First, the raw material is fed into the distillation cavity 1014 inside the distillation tank 101 through the feed pipe 102. Then, the end cap 1011 and the distillation tank 101 are placed together and installed by locking bolts 1013 to ensure the sealing of the distillation tank 101. Then, the heating resistance wire 1041 is activated to perform distillation on the raw material inside. The distilled liquid is discharged out through the cooling pipe 106.

[0058] Step 2: Start the drive motor 201. The drive motor 201 drives the turntable 2012 at the bottom of the rotating shaft 2011 to start rotating. The rotation of the turntable 2012 will cause the stirring rod 2013 at the bottom to start rotating. The stirring rod 2013 can mix the raw materials and reduce the occurrence of scorching at the bottom during the distillation process.

[0059] Step 3: The rotation of turntable 2012 causes the position of the limiting groove 2022 on the surface to change, thereby causing the limiting slider 2021 and the push rod 202 on the surface to move intermittently left and right. When the push rod 202 moves to the left, it causes the sealing plate 2024 to move towards the position of the baffle 2071. At this time, the baffle 2071 is in a self-locking state, that is, the space between the sealing plate 2024 and the baffle 2071 becomes smaller, thereby achieving the purpose of increasing the gas pressure. At this time, the cooling cavity 1061 on the outer wall is connected to ice water, which turns the gas into liquid by cooling and depressurizing, thus facilitating later collection.

[0060] Step 4: During the movement of the sealing plate 2024, the push rod 2032 and connecting plate 204, which are lifted by the synchronous rod 2031 on the surface, begin to move inward. The movement of the connecting plate 204 will cause the guide protrusion 205 to slide along the third slide groove 2043, move to the first slide groove 2041 through the second slide groove 2042, and drive the insert plate 2051 connected to the guide protrusion 205 to move upward, thereby driving the positioning rack 206 connected at the end to move upward, so that the positioning rack 206 and the drive gear 2061 are separated, thereby releasing the self-locking state of the baffle 2071. The baffle 2071 is opened by the influence of internal pressure, thereby discharging the internal liquid, and can be resealed by the internal torsion spring 2063.

[0061] Step 5: The discharged liquid flows into the collection box 108 through the guide plate 1081. The internal state can be observed through the tempered glass 1072. The sealing door 1073 can be opened through the handle 1074 to facilitate the removal of the collection box 108.

[0062] Working principle:

[0063] First, the raw material is fed into the distillation cavity 1014 inside the distillation tank 101 through the feed pipe 102. Then, the end cap 1011 and the distillation tank 101 are placed together and installed by locking bolts 1013 to ensure the sealing of the distillation tank 101. Then, the heating resistance wire 1041 is activated to perform distillation on the raw material inside. The distilled liquid is discharged out through the cooling pipe 106.

[0064] Start the drive motor 201, which drives the turntable 2012 at the bottom of the rotating shaft 2011 to start rotating. The rotation of the turntable 2012 will cause the stirring rod 2013 at the bottom to start rotating. The stirring rod 2013 can mix the raw materials and reduce the occurrence of scorching at the bottom during the distillation process.

[0065] The rotation of turntable 2012 causes the position of the limiting groove 2022 on the surface to change, thereby causing the limiting slider 2021 and the push rod 202 on the surface to move intermittently left and right, while the sealing plate begins to move simultaneously. When the push rod 202 moves to the left, it causes the sealing plate 2024 to move towards the baffle 2071. At this time, the baffle 2071 is in a self-locking state, that is, the space between the sealing plate 2024 and the baffle 2071 becomes smaller, thereby achieving the purpose of increasing the gas pressure. At this time, the cooling cavity 1061 on the outer wall is connected to ice water, which turns the gas into liquid by cooling and depressurizing, thus facilitating subsequent collection.

[0066] During the movement of the sealing plate 2024, the push rod 2032 and connecting plate 204, which are lifted by the synchronous rod 2031 on the surface, begin to move inward. The movement of the connecting plate 204 will cause the guide protrusion 205 to slide along the third slide groove 2043, move to the first slide groove 2041 through the second slide groove 2042, and drive the insert plate 2051 connected to the guide protrusion 205 to move upward. This will drive the positioning rack 206 connected at the end to move upward, causing the positioning rack 206 and the drive gear 2061 to separate, thereby releasing the self-locking state of the baffle 2071. The baffle 2071 is opened by the internal pressure, thereby discharging the internal liquid, and can be resealed by the internal torsion spring 2063.

[0067] The discharged liquid flows into the collection box 108 through the guide plate 1081. The internal condition can be observed through the tempered glass 1072. The sealing door 1073 can be opened through the handle 1074 to easily remove the collection box 108.

6. A method of using a C10 crude aromatics distillation apparatus, characterized in that, The operation steps of the C10 crude aromatics distillation apparatus as described in claim 5 are as follows: Step 1: First, the raw material is fed into the distillation cavity (1014) inside the distillation tank (101) through the feed pipe (102). Then, the end cap (1011) of the distillation tank and the distillation tank (101) are placed together and installed by locking bolts (1013) to ensure the sealing of the distillation tank (101). The heating resistance wire (1041) is then activated to perform distillation on the raw material inside. The distilled liquid is discharged out through the cooling pipe (106). Step 2: Start the drive motor (201). The drive motor (201) drives the turntable (2012) at the bottom of the rotating shaft (2011) to start rotating. The rotation of the turntable (2012) will cause the stirring rod (2013) at the bottom to start rotating. The stirring rod (2013) mixes the raw materials, reducing the occurrence of scorching at the bottom during the distillation process. Step 3: The rotation of the turntable (2012) causes the position of the limiting groove (2022) on the surface to change, thereby causing the limiting slider (2021) and the push rod (202) on the surface to move intermittently left and right. When the push rod (202) moves to the left, it causes the sealing plate (2024) to move towards the baffle (2071). At this time, the baffle (2071) is in a self-locking state, that is, the space between the sealing plate (2024) and the baffle (2071) becomes smaller, thereby achieving the purpose of increasing the gas pressure. At this time, the cooling cavity (1061) on the outer wall is connected to ice water, which turns the gas into liquid by cooling and depressurizing, thus facilitating later collection. Step 4: During the movement of the sealing plate (2024), the push rod (2032) and connecting plate (204) lifted by the synchronous rod (2031) on the surface begin to move inward. The movement of the connecting plate (204) will drive the guide protrusion (205) to slide along the third slide groove (2043), move to the first slide groove (2041) through the second slide groove (2042), and drive the insert plate (2051) connected to the guide protrusion (205) to move upward, thereby driving the positioning rack (206) connected at the end to move upward, so that the positioning rack (206) and the drive gear (2061) are separated, thereby releasing the self-locking state of the baffle (2071). The baffle (2071) is opened by the influence of the internal pressure, thereby draining the internal liquid and resealing through the internal torsion spring (2063). Step 5: The discharged liquid flows into the collection box (108) through the guide plate (1081). The internal state can be observed through the tempered glass (1072). The sealed door (1073) can be opened by the handle (1074) to facilitate the removal of the collection box (108).
