Description

Technical Field

[0001] The invention relates to the technical field of heavy aromatic hydrocarbon separation, and in particular to a device for separating C10 heavy aromatic hydrocarbons. Background Art

[0002] C10 heavy aromatics mainly refer to the aromatic fraction containing ten carbon atoms obtained by catalytic reforming and cracking to produce ethylene, including tetramethylbenzene, unimethylenetetramethylbenzene, durene, methylpropylbenzene, butylbenzene, diethylbenzene, methylindene, naphthalene, etc. C10 aromatics account for about 5% of reforming heavy aromatics, of which tetramethylbenzene accounts for 2% to 3%. C10 aromatics account for 10% of pyrolysis gasoline heavy aromatics.

[0003] Tetramethylbenzene accounts for about 0.5%.

[0004] The existing separation device for ten-carbon aromatic hydrocarbons generally separates tetramethylbenzene and naphthalene therein. The separation of ten-carbon aromatic hydrocarbons generally involves vaporizing the ten-carbon aromatic hydrocarbons first and then condensing them to obtain tetramethylbenzene-rich liquid. The condensation treatment efficiency of the existing separation device is low, so the separation effect of the ten-carbon aromatic hydrocarbons is poor, resulting in low recovery efficiency. Therefore, a separation device for ten-carbon aromatic hydrocarbons is needed. Summary of the invention

[0005] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a separation device for ten-carbon heavy aromatics.

The storage tank is located below the condensation shell. The storage tank is a rectangular shell with an open top. The storage tank is connected to the steam generator through a first connecting pipe. A scraper is provided below the bottom plate surface of the condensation shell. The scraper is in contact with the bottom plate surface of the condensation shell. The scraper is fixedly connected to the storage tank through a connecting frame.

[0011] As a further improvement of the technical solution, the guide column is a rubber column with a rough surface, and magnet one and magnet two are respectively provided on the opposite side walls of the storage trough. A support plate is vertically extended downward from the closed end of the condensation shell, and a suction block is provided on the surface of the support plate. The suction block is made of an iron block. In the initial state, the sliding block is at the bottom end of the guide column.

[0012] As a further improvement of the present technical solution, a heat dissipation mechanism is provided at the open end of the condensing shell, and the heat dissipation mechanism includes a mounting bar, gear one, gear two, and fan blades. The mounting bar is fixed to the open end of the condensing shell, and the gear one is coaxially fixedly sleeved on the output shaft end of the motor. The fan blades are rotatably installed on the mounting bar. A plurality of fan blades are provided and are evenly spaced.

[0017] When the scraper scrapes off the tetramethylbenzene-rich liquid on the bottom plate of the condensing shell, the storage tank is always far away from the bottom of the scraper, so as to prevent the scraped tetramethylbenzene-rich liquid from falling into the storage tank, and the steam in the storage tank can be dispersed in the scraped area of ​​the bottom plate of the condensing shell, thereby improving the condensation efficiency of the steam;

[0018] When the motor drives the fan blades to rotate, it can speed up the flow of air in the condensation shell, thereby speeding up the heat dissipation of the condensation shell and improving the condensation effect of steam;

[0019] When the scraped tetramethylbenzene-rich liquid falls onto the guide plate and flows down to the collection shell, the buoyancy of the liquid causes the float to float up, the leakage port opens, and the tetramethylbenzene-rich liquid can flow into the collection shell through the leakage port. When there is no liquid on the collection shell, the leakage port is in a closed state, thereby preventing heavy aromatic hydrocarbon vapor from flowing into the collection shell.

[0039] like Figure 1-Figure 11 As shown, a separation device for ten-carbon aromatics comprises:

[0040] The production room 10, the steam generator 110, the condenser 120, and the condensation production mechanism 20 are provided with a condensation shell 130 in the production room 10. The condensation shell 130 is a cylindrical shell with an opening at one end and a closing at the other end. The opening end of the condensation shell 130 passes through the wall of the production room 10 and faces outward. The closed end of the condensation shell 130 is in the production room 10. The bottom plate of the condensation shell 130 is arranged in an inclined manner. The steam generator 110 and the condenser 120 are located on one side of the production room 10. The condensation production mechanism 20 includes a transmission assembly 210, a condensation tank 220, and a storage tank 230. The transmission assembly 210 includes a support plate 211, a motor 2 12, a screw rod 213, a guide rod 214, a support plate 211 fixed to the wall of the production room 10 and close to the open end of the condensation shell 130, a motor 212 installed on the support plate 211, an output shaft of the motor 212 is parallel to the bottom plate surface of the condensation shell 130, one end of the screw rod 213 is coaxially fixedly connected to the output shaft end of the motor 212, the other end of the screw rod 213 is rotatably connected to the closed end of the condensation shell 130, the guide rod 214 is arranged parallel to one side of the screw rod 213, the condensation tank 220 is sleeved on the screw rod 213 and the guide rod 214 through a displacement block 221, and the condensation tank 220 is located in the condensation shell 130.

[0041] More specifically, the condensation tank 220 is a tank structure with a closed top and an open bottom. The bottom of the condensation tank 220 is in matching contact with the bottom inner wall of the condensation shell 130. The condensation tank 220 is connected to the condenser 120 through a connecting pipe 121. The storage tank 230 is located below the condensation shell 130. The storage tank 230 is a rectangular shell with an open top. The storage tank 230 is connected to the steam generator 110 through a connecting pipe 111. A scraper 222 is provided below the bottom plate surface of the condensation shell 130. The scraper 222 is in contact with the bottom plate surface of the condensation shell 130. The scraper 222 is fixedly connected to the storage tank 230 through a connecting frame 223. The scraper 222 and the storage tank 230 are connected through a connecting component 240.

[0042] like Figure 5-Figure 7 As shown, the connecting assembly 240 includes a bracket 241 and a guide column 242. The bracket 241 is fixed to the bottom of the scraper 222, and the guide column 242 is fixed to the bracket 241. The guide column 242 is parallel to the bottom plate surface of the condensation shell 130 and perpendicular to the length direction of the scraper 222. The storage trough 230 is mounted on the guide column 242 through a sliding block 231. The storage trough 230 can move along the guide column 242, and a guide plate 140 is arranged below the storage trough 230.

[0043] More specifically, the guide column 242 is a rubber column with a rough surface, and magnet 1 232 and magnet 233 are respectively arranged on the opposite side walls of the storage tank 230. The closed end of the condensation shell 130 is vertically extended downward to be provided with a support plate 131, and a suction block 132 is arranged on the plate surface of the support plate 131. The suction block 132 is made of an iron block. In the initial state, the sliding block 231 is at the bottom end of the guide column 242, and the heavy aromatic hydrocarbon raw material is placed in the steam generator 110 for vaporization, and then the steam flows into the storage tank 230 through the connecting pipe 111, and then the steam is discharged through the top opening of the storage tank 230 and dispersed to the bottom of the bottom plate surface of the condensation shell 130. The condenser 120 cools the bottom plate surface of the condensation shell 130 through the connecting pipe 2 121, so that the steam dispersed to the bottom of the bottom plate surface of the condensation shell 130 condenses, and the motor 212 drives the condensation tank 220 to move along the bottom plate surface of the condensation shell 130, so that the bottom plate surface of the condensation shell 130 can be fully cooled. At this time, the scraper 222 moves along the bottom of the bottom plate of the condensing shell 130, thereby scraping off the tetramethylbenzene liquid condensed on the bottom plate of the condensing shell 130, and the scraped tetramethylbenzene liquid falls to the upper and lower streams of the guide plate 140, thereby collecting the tetramethylbenzene liquid separated from the heavy aromatics. When the scraper 222 moves up to the top along the bottom of the bottom plate of the condensing shell 130, the magnet 233 is attracted to the suction block 132, and then the motor 212 drives the condensing tank 220 and the scraper 222 to move upward. The storage tank 230 moves downward along the guide column 242, and the sliding block 231 is at the top of the guide column 242. Therefore, when the scraper 222 scrapes the tetramethylbenzene-rich liquid on the bottom surface of the condensation shell 130, the storage tank 230 is always away from the scraper 222, thereby preventing the scraped tetramethylbenzene-rich liquid from falling into the storage tank 230, and the steam in the storage tank 230 can be dispersed in the scraped area of ​​the bottom surface of the condensation shell 130, thereby improving the condensation efficiency of the steam.

[0044] like Figure 7-Figure 9 As shown, a heat dissipation mechanism 250 is provided at the open end of the condensing shell 130, and the heat dissipation mechanism 250 includes a mounting bar 251, a gear 1 252, a gear 253, and a fan blade 254. The mounting bar 251 is fixed to the open end of the condensing shell 130, the gear 1 252 is coaxially fixedly sleeved on the output shaft end of the motor 212, and the fan blade 254 is rotatably mounted on the mounting bar 251. The fan blade 254 is provided with multiple and evenly spaced arrangements, the gear 2 253 is coaxially fixedly sleeved on the central shaft end of a fan blade 254, the gear 2 253 is meshed with the gear 1 252, and the fan blades 254 are driven by a belt. When the motor 212 drives the fan blade 254 to rotate, the fluidity of the air in the condensing shell 130 can be accelerated, thereby accelerating the heat dissipation of the condensing shell 130 and improving the condensation effect on the steam.

[0045] like Figure 10-11As shown, a collecting shell 150 is provided at the bottom end of the guide plate 140. The collecting shell 150 is a rectangular shell. A leakage port 151 is opened on the top plate surface of the collecting shell 150. A connecting column 152 is vertically arranged in the leakage port 151. A float 153 is arranged on the top of the connecting column 152. A limiting plate 154 is arranged at the bottom of the connecting column 152. The float 153 is outside the collecting shell 150. When the scraped tetramethylbenzene-rich liquid falls onto the guide plate 140 and flows down to the collecting shell 150, the buoyancy of the liquid causes the float 153 to float up, the leakage port 151 is opened, and the tetramethylbenzene-rich liquid can flow into the collecting shell 150 through the leakage port 151. When there is no liquid on the collecting shell 150, the leakage port 151 is in a closed state, thereby preventing heavy aromatic hydrocarbon vapor from flowing into the collecting shell 150.

[0046] More specifically, the bottom of the collecting shell 150 is connected to a discharge pipe 160 to facilitate the discharge of the tetramethylbenzene-rich liquid in the collecting shell 150 .

[0047] More specifically, a feeding port is provided at the top of the condensation tank 220 , and a cover plate 224 is provided at the feeding port. In winter, ice cubes can be placed in the condensation tank 220 through the feeding port to condense the condensation shell 130 , thereby saving resources.

[0048] Working principle:

[0049] During the use of the present invention, the heavy aromatic hydrocarbon raw material is placed in the steam generator 110 for vaporization, and then the steam flows into the storage tank 230 through the connecting pipe 111, and then the steam is discharged through the top opening of the storage tank 230 and dispersed to the bottom of the bottom plate surface of the condensing shell 130. The condenser 120 cools the bottom plate surface of the condensing shell 130 through the connecting pipe 2 121, so that the steam dispersed to the bottom of the bottom plate surface of the condensing shell 130 is condensed, and the motor 212 drives the condensing tank 220 to move along the bottom plate surface of the condensing shell 130. The bottom plate surface of the condensation shell 130 can be fully cooled. At this time, the scraper 222 moves along the bottom of the bottom plate surface of the condensation shell 130, thereby scraping off the tetramethylbenzene liquid condensed on the bottom plate surface of the condensation shell 130, and the scraped tetramethylbenzene liquid falls to the upper and lower streams of the guide plate 140, thereby collecting the tetramethylbenzene liquid separated from the heavy aromatics. When the scraper 222 moves up to the top along the bottom of the bottom plate surface of the condensation shell 130, the magnet 233 is attracted to the suction block 132, and then the motor 212 drives the condensation tank 220, the scraper 222, and the suction block 132. The plate 222 moves downward, and the storage tank 230 moves along the guide column 242. The sliding block 231 is at the top of the guide column 242, so that when the scraper 222 scrapes the tetramethylbenzene liquid on the bottom plate surface of the condensing shell 130, the storage tank 230 is always away from the bottom of the scraper 222, thereby preventing the scraped tetramethylbenzene liquid from falling into the storage tank 230, and the steam in the storage tank 230 can be dispersed in the scraped area of ​​the bottom plate surface of the condensing shell 130, thereby improving the condensation efficiency of the steam. The motor 212 drives the fan blade 254 When rotating, the flow of air in the condensation shell 130 can be accelerated, thereby accelerating the heat dissipation of the condensation shell 130 and improving the condensation effect on the steam. When the scraped tetramethylbenzene-rich liquid falls onto the guide plate 140 and flows down to the collection shell 150, the buoyancy of the liquid causes the float 153 to float up, and the leakage port 151 opens. The tetramethylbenzene-rich liquid can flow into the collection shell 150 through the leakage port 151. When there is no liquid on the collection shell 150, the leakage port 151 is in a closed state, thereby preventing heavy aromatic hydrocarbon vapor from flowing into the collection shell 150.

[0050] It should be noted that the above specific implementations are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art should understand that various modifications, equivalent substitutions, changes, etc. can be made to the present invention. However, as long as these changes do not deviate from the spirit of the present invention, they should be within the scope of protection of the present invention.
