Abstract
Description
Technical Field
[0001] This utility model relates to the field of coking treatment technology, and in particular to an apparatus for dissolving anthraquinone polymers. Background Technology
[0002] The anthracene tower vacuum pump draws wash oil from the side wall of the vacuum tank. The liquid ring vacuum pump in the anthracene tower vacuum system utilizes a pump casing half-filled with wash oil. When the impeller rotates, a liquid ring forms. This liquid ring acts as a liquid seal, creating numerous small, distinct sealed chambers with the impeller blades. As the space in these chambers increases, gas is drawn in through the inlet; as the space decreases, gas is discharged through the outlet. Because the composition of the anthracene tower exhaust gas is complex, polymers of higher phenols may form within the system. These polymers have complex structures, large relative molecular masses, and are highly dispersed. Over prolonged operation, these polymers can clog the liquid ring pipe and pump head, causing the vacuum pump to malfunction and affecting the normal operation of the anthracene tower vacuum system and the anthracene tower itself.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Example 1:
[0022] Reference Figure 1-4 An apparatus for dissolving anthracene phenol polymer includes a tank 1 and a sealing plate 2 at the top of the tank 1. A discharge pipe 4 is connected to the center of the bottom outer wall of the tank 1, and a cleaning structure 6 is provided on the outer wall of one end of the tank 1. A heating component 7 is provided in the cleaning structure 6, and a valve 5 is installed at one end of the discharge pipe 4. After implementation, the anthracene vacuum system can operate for a long time without causing unplanned anthracene production stoppage, thus reducing economic losses.
[0023] The top outer wall of the sealing plate 2 is connected to the inlet pipe 3, and the outer wall of the sealing plate 2 is equipped with a vacuum pump 8. Every 12 hours, the high-temperature washing oil of 100 degrees Celsius is used to replace the polymer of high-grade phenol in the tank 1, so as to treat the high-grade phenol polymer, avoid blockage, and avoid loss.
[0024] The vacuum pump 8, oil pump mechanism 14, electric heat tracing 18, and heater 17 are connected to a switch via wires, and the switch is connected to a power source via wires.
[0025] Example 2:
[0026] Reference Figure 1-3 The cleaning structure 6 includes a cleaning tank 11, a conveying pipe 10 connected to the center of the bottom of the cleaning tank 11, a disassembly plate 12 installed on the outer wall of the top of the cleaning tank 11, and a cleaning pipe 9 embedded in the outer wall of the top of the tank 1. The washing oil acts on the inner wall of the tank 1 and uses high temperature washing oil to dissolve most of the high phenolic polymer on the inner wall of the tank 1. The dissolved high phenolic polymer is located in the washing oil. Then, the discharge pipe 4 and valve 5 are opened to discharge the washing oil along with the high phenolic polymer.
[0027] An electric heat tracing device 18 is installed on the outer wall of the conveying pipe 10, and a valve 2 15 is installed on the outer wall of one end of the conveying pipe 10;
[0028] The bottom outer wall of the cleaning tube 9 is provided with equally spaced liquid outlets 19, and the other end of the delivery tube 10 is connected to the cleaning tube 9.
[0029] The heating assembly 7 includes mounting slots 16 that are equidistantly opened on the inner wall of the cleaning tank 11 and a heater 17 installed on the inner wall of the mounting slots 16. The heater 17 inside the cleaning tank 11 is activated, and the heater 17 heats the washing oil inside the cleaning tank 11. The temperature sensor monitors the temperature of the washing oil.
[0030] The bottom outer wall of the cleaning tank 11 is connected to an oil pump mechanism 14, and the output end of the oil pump mechanism 14 is connected to one end of the delivery pipe 10. The input end of the oil pump mechanism 14 is connected to the bottom inner wall of the cleaning tank 11. The motor in the oil pump mechanism 14 drives the oil pump to draw high-temperature washing oil from the cleaning tank 11 and deliver it to the delivery pipe 10. The electric heat tracing 18 is started to preheat the delivery pipe 10. The high-temperature washing oil enters the cleaning pipe 9 through the delivery pipe 10. The electric heat tracing 18 prevents the temperature of the washing oil in the delivery pipe 10 from dropping.
[0031] A temperature sensor is installed on the inner wall of the cleaning tank 11, and an addition pipe 13 is provided on the top outer wall of the disassembly plate 12. The cleaning oil used in the cleaning tank 1 is added into the cleaning tank 11 through the addition pipe 13.
[0032] Working principle: During use, the washing oil containing high-grade phenol polymers in tank 1 is first discharged from the drain pipe 4 at the bottom of tank 1 to reduce the content of high-grade phenol polymers. The washing oil used to clean tank 1 is then added into cleaning tank 11 through the addition pipe 13. The heater 17 inside cleaning tank 11 is activated to heat the washing oil inside. A temperature sensor monitors the temperature of the washing oil. Valve 15 at one end of the delivery pipe 10 is opened, and the oil pump mechanism 14 is started. The motor in the oil pump mechanism 14 drives the oil pump to draw the high-temperature washing oil from cleaning tank 11 and deliver it to the delivery pipe 10. The electric heating tracing 18 is then activated to heat the delivery pipe 10. Preheating is performed, and high-temperature wash oil enters the cleaning pipe 9 through the delivery pipe 10. Then, the wash oil is sprayed out from the outlet 19 at the bottom of the cleaning pipe 9. The wash oil acts on the inner wall of the tank 1, and the high-temperature wash oil dissolves most of the high-grade phenolic polymers on the inner wall of the tank 1. The dissolved high-grade phenolic polymers are located in the wash oil. Then, the discharge pipe 4 and valve 5 are opened to discharge the wash oil along with the high-grade phenolic polymers. Every 12 hours, 100-degree Celsius high-temperature wash oil is used to replace the high-grade phenolic polymers in the tank 1 to treat the high-grade phenolic polymers, avoid blockage, and avoid losses. After implementation, the anthracene tower vacuum system can operate for a long time without causing unplanned anthracene tower shutdowns, reducing economic losses.
[0033] During normal production, the anthracene tower produces 4.0 tons of wash oil and 3.5 tons of anthracene oil per hour. The wash oil is worth about 3200 yuan / ton and the anthracene oil is worth about 3300 yuan / ton. The economic benefits are: 2 cycles × (2 times × 8 hours × 3.5 tons × 3300 yuan + 2 times × 8 hours × 4.0 tons × 3200 yuan) = 779200 yuan.
[0034] After implementation, the anthracene tower vacuum system can operate for a long time without causing unplanned anthracene tower production stoppages, reducing economic losses by 779,000 yuan.
