Description

Technical Field

[0001] This application belongs to the field of testing technology, and particularly relates to a testing device for the condensation temperature of asphalt fume. Background Art

[0002] At present, during the production process of asphalt, a large amount of asphalt fume is generated in the processes of forming and roasting anodes for aluminum production. In addition, a large amount of asphalt fume is also generated during the laying and repair processes of asphalt roads. Its components are complex and contain a large amount of carcinogenic components, which are very harmful to the human body. At the same time, asphalt fume pollutes the environment. Therefore, asphalt fume must be purified to meet the standards before being discharged, and the main method for purifying asphalt fume is incineration. The incineration method utilizes the flammability of asphalt fume, has a high efficiency in removing benzo[a]pyrene, and can thoroughly purify asphalt fume.

[0003] To reduce energy consumption, carbon enterprises will use existing high-temperature furnaces to incinerate asphalt fume. Asphalt fume is a mixed smoke of polycyclic aromatic hydrocarbons and other organic compounds generated by heating asphalt and burning substances containing asphalt. Its components are complex. If the fume temperature decreases, it will condense in advance on the inner wall of the pipeline, adhere to the inner wall of the pipeline, and over time, it will cause pipeline blockage.

[0004] Different asphalts will produce different asphalt fumes, and the condensation temperature of each asphalt fume is different. In the prior art, when transporting asphalt fume, it is impossible to timely adjust the heat preservation temperature of asphalt fume according to the type of asphalt. If the heat preservation temperature is low, it will cause the condensation of asphalt fume. If the heat preservation temperature is high, it will result in high energy consumption. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a testing device for the condensation temperature of asphalt fume, aiming to at least solve to a certain extent the technical problem that it is impossible to timely adjust the heat preservation temperature of asphalt fume according to the type of asphalt when transporting asphalt fume.

[0006] The technical solution of the present invention is as follows:

[0007] A testing device for the condensation temperature of asphalt fume includes: a first heating container for containing asphalt particles; a second heating container; a connecting pipeline connecting the first heating container and the second heating container; a liquid level detection component, part of which is arranged outside the second heating container and the other part is arranged inside the second heating container, and the liquid level detection component is connected to the connecting pipeline and the second heating container; and a fan connected to the second heating container.

[0008] In some embodiments, the first heating container includes: a first container for containing the asphalt particles; and a first heating jacket sleeved outside the first container.

[0009] In some embodiments, the first container is provided with a filling port, and the testing device further includes: a safety valve, connected to the first container and disposed at the filling port.

[0010] In some embodiments, the second heating container includes: a second container; a second heating jacket sleeved outside the second container.

[0011] In some embodiments, the connecting pipeline includes: a first pipeline, communicating with the first heating container and located outside the first heating container and the second heating container; a second pipeline, communicating with the first pipeline and the liquid level detection assembly and located inside the second heating container.

[0012] In some embodiments, the second pipeline includes a serpentine pipe.

[0013] In some embodiments, the first pipeline is sleeved outside a third heating jacket.

[0014] In some embodiments, the liquid level detection assembly includes: a first pipe, part of which is located inside the second heating container and the other part penetrates through the second heating container, and the first pipe communicates with the connecting pipeline; a second pipe, communicating with the first pipe at an angle and located inside the second heating container, and the second pipe communicates with the second heating container; a third pipe, communicating with the first pipe at an angle and located outside the second heating container; a non-contact liquid level sensor, connected to the first pipe and located outside the second heating container.

[0015] In some embodiments, the diameter of the second pipe is larger than that of the first pipe, and the diameter of the third pipe is smaller than that of the first pipe.

[0016] In some embodiments, the volume of the first heating container is Am3, the volume of the asphalt particles in the first heating container is 1 / 2 Am3 to 3 / 4 Am3, the flow rate of the fan is Qm3 / h, and the fan can completely extract the asphalt fumes in the first heating container at a frequency of n times / min; wherein, Q = (1 / 4A to 1 / 2A) * n * 60.

[0017] The beneficial effects of the present invention at least include:

[0018] Since the first heating container is used to accommodate asphalt particles, the connecting pipeline connects the first heating container and the second heating container, and the fan is connected to the second heating container, therefore, when the first heating container heats the asphalt particles, the asphalt particles will generate asphalt fumes. When the asphalt starts to melt, the fan is started, and under the action of the fan, the asphalt fumes enter the second heating container through the connecting pipeline.

[0019] Since part of the liquid level detection component is arranged outside the second heating container and the other part is arranged inside the second heating container, and the liquid level detection component is communicated with the connecting pipe and the second heating container, during the process that the asphalt fume enters the second heating container through the connecting pipe, the second heating container heats the asphalt fume. After running for a period of time, observe whether there is a reading on the liquid level detection component. If there is a reading on the liquid level detection component, it indicates that the asphalt fume condenses to form a condensate. Increase the heating temperature of the second heating container, and continue to observe whether there is a change in the reading of the liquid level detection component. If the reading of the liquid level detection component continuously decreases, it indicates that the condensate is evaporating, that is, the heating temperature of the second heating container is higher than the condensation point of the condensate. Then gradually decrease the heating temperature of the second heating container until the reading of the liquid level detection component starts to increase. The increase in the reading of the liquid level detection component indicates that the asphalt fume condenses again. Record the heating temperature of the second heating container at this time, and this heating temperature is the condensation temperature of the asphalt fume. By adopting the above method, different types of asphalt particles can be placed in the first heating container to obtain the condensation temperatures of the asphalt fumes of different types of asphalt particles.

[0020] According to the obtained condensation temperature of the asphalt fume, set the heat preservation temperature of the asphalt fume so that the heat preservation temperature matches the condensation temperature, which can avoid the condensation of the asphalt fume, ensure the normal transportation of the asphalt fume, and also avoid high energy consumption, achieving the purpose of saving energy.

[0036] Next, the present application will be described in conjunction with the accompanying drawings and with reference to specific embodiments:

[0037] A test device for the condensation temperature of asphalt fumes provided in this embodiment aims to at least solve to a certain extent the technical problem that when transporting asphalt fumes, the insulation temperature of the asphalt fumes cannot be adjusted in a timely manner according to the type of asphalt.

[0038] Figure 1 The structural schematic diagram of the test device for the condensation temperature of asphalt fume in some embodiments. In combination with Figure 1 , the test device for the condensation temperature of asphalt fume in the embodiments of the present application includes: a first heating container 10, a second heating container 20, a connecting pipe 30, a liquid level detection component 40, and a fan 50. The first heating container 10 is used to contain asphalt particles. The connecting pipe 30 connects the first heating container 10 and the second heating container 20. The liquid level detection component 40 is partially arranged outside the second heating container 20 and another part is arranged inside the second heating container 20. The liquid level detection component 40 is communicated with the connecting pipe 30 and the second heating container 20. The fan 50 is communicated with the second heating container 20.

[0039] Since the first heating container 10 is used to contain asphalt particles, the connecting pipe 30 connects the first heating container 10 and the second heating container 20, and the fan 50 is communicated with the second heating container 20. Therefore, when the first heating container 10 heats the asphalt particles, asphalt fume will be generated. When the asphalt starts to melt, the fan 50 is started. Under the action of the fan 50, the asphalt fume enters the second heating container 20 through the connecting pipe 30.

[0040] Since the liquid level detection component 40 is partially arranged outside the second heating container 20 and another part is arranged inside the second heating container 20, and the liquid level detection component 40 is communicated with the connecting pipe 30 and the second heating container 20, so, during the process that the asphalt fume enters the second heating container 20 through the connecting pipe 30, the second heating container 20 heats the asphalt fume. After running for a period of time, observe whether there is a reading on the liquid level detection component 40. If there is a reading on the liquid level detection component 40, it indicates that the asphalt fume condenses to form a condensate. Increase the heating temperature of the second heating container 20, and continue to observe whether there is a change in the reading of the liquid level detection component 40. If the reading of the liquid level detection component 40 continuously decreases, it indicates that the condensate is evaporating, that is, the heating temperature of the second heating container 20 is higher than the condensation point of the condensate. Then gradually decrease the heating temperature of the second heating container 20 until the reading of the liquid level detection component 40 starts to increase. The increase in the reading of the liquid level detection component 40 indicates that the asphalt fume condenses again. Record the heating temperature of the second heating container 20 at this time. This heating temperature is the condensation temperature of the asphalt fume. By adopting the above method, different types of asphalt particles can be placed in the first heating container 10 to obtain the condensation temperatures of the asphalt fumes of different types of asphalt particles.

[0041] According to the obtained condensation temperature of the asphalt fume, set the insulation temperature of the asphalt fume so that the insulation temperature matches the condensation temperature, which can avoid the condensation of the asphalt fume, ensure the normal transportation of the asphalt fume, and also avoid high energy consumption, achieving the purpose of saving energy.

[0042] In some embodiments, in order to adjust the heating temperature of the second heating container 20, the test device for the condensation temperature of asphalt fumes further includes: a thermostat. The thermostat is electrically connected to the second heating container 20 and is used to adjust the heating temperature of the second heating container 20. Among them, the thermostat can be a temperature control key.

[0043] In some embodiments, the fan 50 is communicated with the asphalt fume purification system and is used to convey the asphalt fumes in the second heating container 20 to the asphalt fume purification system, and the asphalt fumes are purified by the asphalt fume purification system to avoid causing pollution.

[0044] Combined Figure 1 With reference to, in some embodiments, in order to heat the asphalt particles, the first heating container 10 includes: a first container 11 and a first heating jacket 12. The first container 11 is used to contain asphalt particles. The first heating jacket 12 is sleeved outside the first container 11, and the first heating jacket 12 heats the first container 11 so that the asphalt particles in the first container 11 generate asphalt fumes. Among them, the first heating jacket 12 can be an electric heating jacket.

[0045] The shape of the first heating jacket 12 matches the shape of the first container 11 so that the first heating jacket 12 can be attached to the outer surface of the first container 11 to ensure that the first heating jacket 12 can fully heat the asphalt particles in the first container 11.

[0046] The first container 11 is made of quartz or other materials that can withstand 300 °C, and the first heating jacket 12 can be heated to 300 °C.

[0047] In some embodiments, in order to ensure safety, the first container 11 is provided with a loading port, and the test device further includes: a safety valve 13. The safety valve 13 is connected to the first container 11 and is arranged at the loading port. When the pressure inside the first container 11 is greater than 0.01 MPA, the safety valve 13 automatically opens to relieve pressure and ensure the safety of the first container 11.

[0048] Combined Figure 1 With reference to, in some embodiments, in order to heat the asphalt fumes, the second heating container 20 includes: a second container 21 and a second heating jacket 22. The second heating jacket 22 is sleeved outside the second container 21, and the second heating jacket 22 heats the second container 21 to heat the asphalt fumes in the second container 21. Among them, the thermostat is electrically connected to the second heating jacket 22 to adjust the heating temperature of the second heating jacket 22.

[0049] The second container 21 is made of quartz or other materials that can withstand 500 °C, the second heating jacket 22 can be heated to 500 °C, and the second heating jacket 22 can be an electric heating jacket.

[0050] Combined Figure 1, in some embodiments, in order to convey the asphalt fumes in the first heating container 10 to the second heating container 20, the connecting pipe 30 includes: a first pipe 31 and a second pipe 32. The first pipe 31 is connected to the first heating container 10 and is located outside the first heating container 10 and the second heating container 20. The second pipe 32 is connected to the first pipe 31 and the liquid level detection assembly 40 and is located inside the second heating container 20.

[0051] When the asphalt starts to melt, the fan 50 is started. Under the action of the fan 50, the asphalt fumes enter the second pipe 32 through the first pipe 31 and enter the liquid level detection assembly 40 and the second heating container 20 through the second pipe 32. The second heating container 20 can heat the asphalt fumes in the second pipe 32 and the liquid level detection assembly 40 to obtain the condensation temperature of the asphalt fumes.

[0052] In some embodiments, in order to ensure that the asphalt fumes are fully heated, the second pipe 32 of the connecting pipe 30 is located in the entire cavity of the second heating container 20, and the liquid level detection assembly 40 is located at the bottom of the second heating container 20 to extend the conveying path of the asphalt fumes.

[0053] In some embodiments, in order to ensure that the asphalt fumes can be fully heated by the second heating container 20, the second pipe 32 includes a serpentine pipe to extend the flow path of the asphalt fumes, so that the asphalt fumes are heated more evenly, avoiding the direct escape of the asphalt fumes in the second heating container 20, making the distribution of the asphalt fumes controllable and ensuring the accuracy of the test.

[0054] In some embodiments, in order to prevent the asphalt fumes from condensing in the first pipe 31, the first pipe 31 is sleeved with a third heating sleeve 33, and the asphalt fumes are heated by the third heating sleeve 33 to ensure smooth conveyance of the asphalt fumes.

[0055] In some embodiments, the third heating sleeve 33 and the second heating sleeve 22 may be an integral structure. Of course, in some other embodiments, the third heating sleeve 33 and the second heating sleeve 22 may also be separate heating sleeves.

[0056] Combined with Figure 1, in some embodiments, in order to detect the liquid level change, the liquid level detection assembly 40 includes: a first pipe 41, a second pipe 42, a third pipe 43 and a non-contact liquid level sensor 44. A part of the first pipe 41 is located inside the second heating container 20, and the other part penetrates through the second heating container 20. The first pipe 41 is communicated with the communication pipe 30. The second pipe 42 is communicated with the first pipe 41 at an angle and is located inside the second heating container 20. The second pipe 42 is communicated with the second heating container 20. The third pipe 43 is communicated with the first pipe 41 at an angle and is located outside the second heating container 20. The non-contact liquid level sensor 44 is connected to the third pipe 43 and is located outside the second heating container 20.

[0057] The asphalt fume enters the first pipe 41 through the communication pipe 30, enters the second pipe 42 through the first pipe 41, and enters the second heating container 20 through the second pipe 42. The second heating container 20 heats the asphalt fume. After operating for a period of time, the non-contact liquid level sensor 44 can detect the liquid level in the first pipe 41 and observe whether there is a reading on the non-contact liquid level sensor 44. If there is a reading on the non-contact liquid level sensor 44, it indicates that the asphalt fume condenses to form a condensate. Increase the heating temperature of the second heating container 20 and continue to observe whether the reading of the non-contact liquid level sensor 44 changes. If the reading of the non-contact liquid level sensor 44 continuously decreases, it indicates that the condensate is evaporating, that is, the heating temperature of the second heating container 20 is higher than the condensation point of the condensate. Then gradually decrease the heating temperature of the second heating container 20 until the reading of the non-contact liquid level sensor 44 starts to increase. The increase in the reading of the non-contact liquid level sensor 44 indicates that the asphalt fume condenses again. Record the heating temperature of the second heating container 20 at this time. This heating temperature is the condensation temperature of the asphalt fume. By adopting the above method, different types of asphalt particles can be placed in the first heating container 10 to obtain the condensation temperature of the asphalt fume of different types of asphalt particles.

[0058] In some embodiments, since the temperature inside the second heating container 20 may reach 500 °C, in order to ensure the safety and normal use of the non-contact liquid level sensor 44, the non-contact liquid level sensor 44 is arranged outside the second heating container 20.

[0059] In some embodiments, in order to ensure smooth flue gas transportation, the diameters of the first pipe 41, the first pipeline 31 and the second pipeline 32 are the same.

[0060] In some embodiments, cooling measures such as air cooling are taken to ensure that the temperature of the first pipe 41 outside the second heating container 20 is less than 100 °C to ensure the safety of the first pipe 41.

[0061] In some embodiments, the third pipe 43 is directly connected to the outside, and pressure relief can be carried out through the third pipe 43 to avoid pipe bursting and ensure safety. Of course, in some other embodiments, the third pipe 43 is connected to the fan 50. When asphalt fume appears in the third pipe 43, the asphalt fume can be guided to the asphalt fume purification system through the fan 50.

[0062] In some embodiments, the non-contact liquid level gauge 44 is a high-precision liquid level gauge with an accuracy in the mm level. The non-contact liquid level gauge 44 has a warning function at zero liquid level.

[0063] In some embodiments, the included angle between the second pipe 42 and the first pipe 41 can be set at 45° to 135°. In this embodiment, only the included angle between the second pipe 42 and the first pipe 41 being 90°, that is, the second pipe 42 is perpendicular to the first pipe 41, is taken as an example for illustration, and it should not be construed as a limitation to this application.

[0064] In some embodiments, the included angle between the third pipe 43 and the first pipe 41 can be set at 45° to 135°. In this embodiment, only the included angle between the third pipe 43 and the first pipe 41 being 90°, that is, the third pipe 43 is perpendicular to the first pipe 41, is taken as an example for illustration, and it should not be construed as a limitation to this application.

[0065] In some embodiments, the third pipe 43 and the second pipe 42 can be arranged in parallel. The third pipe 43 extends towards the top of the second heating container 20, and the second pipe 42 extends towards the top of the second heating container 20. When the asphalt fume condenses, the liquid level in the second pipe 42 is consistent with the liquid level in the third pipe 43.

[0066] In some embodiments, the second pipe 32 of the connecting pipeline 30 is connected to the first pipe 41, and the second pipe 32 is located between the second pipe 42 and the third pipe 43.

[0067] In some embodiments, in order to ensure smooth discharge of asphalt fume, the diameter of the second pipe 42 is larger than the diameter of the first pipe 41, so that the asphalt fume entering the first pipe 41 can smoothly enter the second heating container 20 through the first pipe 41.

[0068] In some embodiments, in order to reduce the amount of leaked asphalt fume, the diameter of the first pipe 41 is larger than the diameter of the third pipe 43, so that the diameter of the third pipe 43 is small. Even if there is asphalt fume leakage, the amount of leaked asphalt fume is small.

[0069] In some embodiments, the diameter of the third pipe is 0.25 to 0.5 times the diameter of the first pipe, and the diameter of the second pipe is 1.5 to 2.5 times the diameter of the first pipe.

[0070] Combined with Figure 1, in some embodiments, in order to fully heat the asphalt particles in the first heating container 20, the test device for the condensation temperature of asphalt fumes further includes: a stirrer 60. The fixed end of the stirrer 60 is located outside the first heating container 10, and the moving end of the stirrer 60 is located inside the first heating container 10. After the asphalt is completely melted, the moving end of the stirrer 60 moves, and the moving end of the stirrer 60 starts to stir the melted asphalt so that the asphalt can be fully heated to generate asphalt fumes.

[0071] In some embodiments, in order to enable the smooth flow of asphalt fumes, the volume of the first heating container 10 is A m 3 , and the volume of the asphalt particles in the first heating container 10 is 1 / 2 A m 3 ~3 / 4 A m 3 , and the flow rate of the fan 50 is Q m 3 / h, and the fan 50 can extract all the asphalt fumes in the first heating container 10 at a frequency of n times / min. Wherein, Q = (1 / 4 A~1 / 2 A) * n * 60.

[0072] The fan 50 can extract all the asphalt fumes in the first heating container 10 at a frequency of 10 times / min. According to Q = (1 / 4 A~1 / 2 A) * 10 * 60 = 150 A~300 A m 3 / h, then the air volume of the induced draft fan is 150~300 times the volume of the first heating container 10, that is, 150 A~300 A m 3 / h.

[0073] Combined with Figure 1 , in some embodiments, in order to support the first heating container 10, the test device for the condensation temperature of asphalt fumes further includes: a first support base 70. The first heating container 10 is arranged on the first support base 70 to realize the support of the first heating container 10.

[0074] Combined with Figure 1 , in some embodiments, in order to support the second heating container 20, the test device for the condensation temperature of asphalt fumes further includes: a second support base 80. The second heating container 20 is arranged on the second support base 80 to realize the support of the second heating container 20.
