[0041] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0043] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0045] The present application embodiment provides an asphalt reaction control system, such as Figure 1 and Figure 2As shown, it includes a heating furnace 10, a heating jacket 20, a reactor 30, an air inlet device 40, a gas processing device 50 and a temperature control device 60, wherein: the heating furnace 10 has multiple accommodating areas arranged inside, the top of which is provided with the heating jacket 20, and the position of the heating jacket 20 opposite to the accommodating area is provided with a reactor through hole to facilitate the removal of the reactor. Each of the multiple reactors 30 is correspondingly arranged in one of the accommodating areas; each reactor 30 includes a main body 301 and a top cover 302, and the top cover 302 is provided with an air inlet pipe interface 3021 and an air outlet pipe interface 3022. The air inlet device 40 is connected to the air inlet pipe interface 3021 of each reactor top cover part through an air inlet pipe 401, and the air inlet device 40 provides reaction gas to the reactor 30. The gas treatment device 50 is connected to the air outlet pipe interface 3022 of each reactor top cover part through an air outlet pipe 501, and the gas treatment device 50 recovers the waste gas discharged from the reactor 30. The temperature control device 60 is connected to the control end of the heating furnace 10 and the heating jacket 20, and the temperature control device 60 controls the temperature value of the heating furnace 10 and the heating jacket 20 to the reaction temperature value.

[0046] The air inlet device 40 can provide various types of gases, such as N2, O2, etc., for asphalt to achieve various reactions such as polymerization and pyrolysis. The present embodiment can also achieve various reaction scenarios such as liquid-liquid reaction and polymerization reaction. Because each reactor 30 has an air inlet at the top, the asphalt reaction in each reactor can be carried out under the required gas. Each reactor 30 has an air outlet, which is further connected to the gas treatment device 50 to treat the waste gas generated in the reaction.

[0047] The above scheme provided by this embodiment can place multiple reactors 30 in the heating furnace 10, and the asphalt samples in different reactors 30 can be heated at the same time. If you want to obtain the parameters of the polymerization or pyrolysis process of the asphalt sample at the same temperature and different reaction times, you only need to take out different reactors 30 at different reaction times and detect the asphalt in the reactor 30 to obtain the required parameters. Therefore, the scheme of this application integrates the polymerization or pyrolysis process of asphalt at the same temperature and different reaction times into one heating furnace 10, concentrates multiple reactors in one heating furnace, and heats up at the same time, which can quickly complete the influence of different temperatures, different reaction times, and different pressures on the polymerization or pyrolysis properties of asphalt, greatly improve the efficiency of the experiment, and quickly determine the optimal reaction time. In addition, the exhaust gas generated by the reaction is treated by the gas treatment device to meet environmental protection requirements.

[0048] In the above scheme of the present application, multiple reactors 30 are heated synchronously and temperature-controlled individually, which is more efficient; the reactors 30 used are independent of each other and will not affect the reaction process during use.

[0049] In some schemes, asphalt reaction control systems, such as Figure 3 As shown, it also includes a heating wire 303, which is pre-buried inside each of the accommodating areas; the temperature control device 60 can also be used to connect to the control end of the heating wire 303, and the temperature control device 60 controls the heating power of the heating wire 303 so that the temperature difference between the inside and the outside of each of the accommodating areas is within the set range. As shown in the figure, the heating wire 303 is evenly distributed on the bottom and side walls of the accommodating area, because the setting channel of each reactor 30 is pre-buried with a heating wire 30, which can ensure the uniformity of heating of the reactor 30, that is, the temperature difference between the inside and the outside is as close to zero as possible. In the figure, heating wire sleeves are installed on the outer wall (4 are evenly installed) and the bottom of the reactor 30, and the heating wire is placed in the sleeves. Figure 3 The figure shows the modular structure of a single reactor 30. The complete set of equipment is a series connection of multiple reactor modules. Preferably, different containing areas in the heating furnace 10 are separated by vacuum interlayers. The vacuum interlayers are used to separate the different containing areas to avoid the influence of heating of each reactor module on each other.

[0050] Furthermore, in the asphalt reaction control system, the air intake device 40 is equipped with a pressure sensor and a pressure regulating valve 402. The pressure sensor detects the gas pressure value in the air intake pipe and sends the gas pressure value to the control unit of the pressure regulating valve 402. The control unit of the pressure regulating valve 402 stores a target pressure value, and the control unit adjusts the opening of the pressure regulating valve 402 according to the difference between the gas pressure value and the target pressure value. When conducting a test of a specific reaction scenario, if the raw asphalt, reaction time and pressure are fixed, the softening point, the mesophase content and the reaction temperature are positively correlated, but the higher the temperature, the faster the growth and development of the mesophase, and the quality will decrease. Therefore, it is necessary to use multiple reactors to simultaneously test the properties of the mesophase asphalt under different conditions to determine the optimal conditions. Through the above reaction scenario, the gas pressure value in each reactor 30 should meet certain requirements. In this scheme, the gas pressure value of the air intake pipe detected by the pressure sensor actually matches the gas pressure value in the reactor. Through the self-control adjustment of the pressure sensor and the pressure regulating valve 402, the purpose of studying the influence of pressure on the polymerization or pyrolysis experimental results of asphalt can be achieved.

[0051] Furthermore, if Figure 1In the asphalt reaction control system shown, the air intake device 40 is equipped with a flow meter 403 and a pressure regulating valve 402. The flow meter 403 is used to detect the gas flow value of the air intake pipe 401 and send the gas flow value to the control unit of the pressure regulating valve 402. The control unit of the pressure regulating valve 402 stores a target flow value, and the control unit adjusts the opening of the pressure regulating valve 402 according to the difference between the gas flow value and the target flow value. Through the self-control adjustment of the flow meter 403 and the pressure regulating valve 402, the purpose of studying the influence of flow on the polymerization or pyrolysis experimental results of asphalt can be achieved.

[0052] Further preferably, the heating furnace 10 and the heating sleeve 20 are provided with temperature sensors, and the temperature sensors detect the actual temperature value of the environment in which they are located and send the actual temperature value to the temperature control device 40; the temperature control device 40 records the actual temperature value and the reception time of the actual temperature value, and obtains the temperature change law of the heating furnace 10 and the heating sleeve 20. If the temperature change law contains a fluctuation value exceeding the set value, a prompt message is issued. The heating furnace 10 mainly provides the reactor 30 with the temperature required for the reaction, and the furnace material is made of copper block to ensure that the temperature fluctuation is within ±1°C; the furnace body insulation part is the outer shell of the entire heating furnace 10, which can play a role in insulation. The flexible heating sleeve 20 mainly ensures the temperature of the top of the heating furnace, and also controls the temperature fluctuation within ±1°C. Therefore, when the temperature change law contains a fluctuation exceeding ±1°C, an alarm prompt message is issued. Further, if Figure 3 As shown, the temperature sensor 44 can also be inserted into the reactor and connected to the external temperature control device 40 for temperature control. This method can directly detect the temperature inside the reactor 30, and control the temperature control device 40 according to the detection result, which can ensure that the reaction temperature of the asphalt meets the requirements and the reaction conditions are more accurate.

[0053] Furthermore, the air intake device 40 includes a plurality of air source devices and a switching valve, and different air source devices are used to provide the gas required by the asphalt in different reaction scenarios; the switching valve switches the air source device used to provide the gas according to the reaction scenario. The air source devices are mainly air intake devices for nitrogen and air, and in specific scenarios, they can be selected and set according to the reaction requirements.

[0054] In some embodiments of the asphalt reaction control system, a device such as the following is provided between the air inlet pipe 401 and the air inlet pipe interface 3021 of the reactor 30: Figure 4The distillation accessory shown in the figure; an outlet pressure sensor 505 is arranged between the outlet pipe interface 3022 of the reactor and the outlet pipe 501; the control unit of the distillation accessory receives the outlet pressure value detected by the outlet pressure sensor 505, and performs the atmospheric distillation mode or the reduced pressure distillation mode according to the outlet pressure value. At the same time, a valve 502 is arranged on the outlet passage where the outlet pressure sensor 505 is arranged, and the valve 502 may include Figure 4 The hand valve 5021 and the automatic control valve 5022 shown. Among the process parameters of the reaction, temperature, pressure and time all have an impact on the reaction. In order to obtain the influence of pressure on the reaction, it is necessary to change the pressure value after fixing the temperature and time to conduct experiments. For the process parameters of the reaction, it is hoped that the ideal product can be obtained under the condition of not harsh reaction conditions. In general, for the polymerization process, the control of the pressure of the reaction system is to suppress or promote the escape of the light component, and then adjust the viscosity of the system to make it conducive to the generation and development of the mesophase. When the pressure in the system is increased, the escape of the fraction of the light component is limited so that it can be condensed in the liquid phase. At this time, the viscosity in the system will be reduced, the rheology will be improved, and it will be more conducive to the fusion and rearrangement of the mesophase spheres, which will promote the degree of anisotropy. But at the same time, the pressure should not be too high, just suitable. If the pressure is too high, it will hinder the fusion of the mesophase spheres. The reactor 30 in this device can be connected to the distillation accessories, and the pressure in the reactor is controlled by the pressure sensor and the automatic control valve at the outlet of the reactor, and the atmospheric or reduced pressure distillation can be realized to further separate the gas-liquid mixture in the reactor. In specific implementation, the vacuum distillation implementation scheme includes: connecting the distillation accessory to the reactor air inlet pipe, closing the vent valve 74, opening the fraction stop valve and evacuating at the exhaust port 77 until the vacuum reaches the value set by the pressure sensor. Use a refrigerant of suitable temperature through one port 761 and out from another port 762. After the liquid in the reaction tank boils, the gas can enter 71 from the air inlet pipe, and after being re-condensed into liquid in the condenser 79, it flows into the fraction receiving bottle 72 through the fraction stop valve 75. The temperature probe 78 can detect the gas phase temperature of the liquid distilled from the reactor to determine the fraction cutting point. If the fraction collecting bottle is replaced, the fraction stop valve 75 can be closed, the vent valve 74 can be opened, and after the air pressure is balanced, the fraction collecting bottle 72 can be removed and replaced, the vent valve 74 can be opened and vacuumed, and after the vacuuming is completed, the vent valve 74 can be closed, the vacuum pump can be removed, and the fraction stop valve 75 can be opened to continue receiving the fraction.

[0055] As shown in the figure, in the asphalt reaction control system, the gas treatment device 50 includes a tubular furnace 503 and an absorption device 504. The waste gas enters the tubular furnace 503 and is burned and then absorbed by the alkali solution in the absorption device 504. This solution realizes environmentally friendly and harmless treatment of waste gas.

[0056] The present application also provides a method for obtaining reaction parameters of the asphalt reaction control system according to any one of the above embodiments, including:

[0057] Step 1: After adding the same mass of the same asphalt sample to each reactor, place the reactors in the receiving area of ​​the heating furnace; specifically, the coal tar can be crushed, weighed and poured into the required reactor to ensure that the sample amount in each reactor is the same. After tightening the reactor top cover and the main body, put it into the heating furnace and connect the air inlet and outlet pipes.

[0058] Step 2: Open the air inlet and air outlet passages of the reactor top cover, wherein the air inlet passage is passed with reaction gas according to the requirements of the reaction scenario;

[0059] Step 3: Adjust the reaction temperature value of the temperature control device, and the temperature control device controls the heating furnace and the heating jacket to heat up to the reaction temperature value; connect the temperature controller with the heating furnace and the flexible heating jacket. Open the inlet valve and outlet valve of each reactor, introduce gas, and start the program to heat up to the required temperature of the reaction.

[0060] Step 4: At different reaction times, take out different reactors in turn and extract the asphalt samples after reaction in each reactor; after a certain reaction time, close the air inlet valve and air outlet valve of the reactor to be taken out, disconnect its air inlet pipe and air outlet pipe, take out the reactor and cool it, and the whole reaction process is completed. After the reactor cools to room temperature, open the top cover and take out the sample for analysis. The oil and gas generated by the reaction are incinerated in a tubular furnace and then further treated with alkali solution.

[0061] Step 5: Obtain parameter characteristics of each asphalt sample after reaction, and store the parameter characteristics in association with the reaction scene and inverse time.

[0062] In a specific embodiment, the reaction temperature can be fixed, and the reaction time can be changed (such as 4 hr, 6 hr, 8 hr, 10 hr, 12 hr) to determine the change law of the properties of the asphalt after the reaction (yield, softening point, mesophase content, etc.) with the reaction time;

[0063] In other specific schemes, by fixing the reaction temperature and reaction time and changing the reaction pressure (normal pressure, 0.4MPa, 0.8MPa, 1.2MPa, 1.6MPa, 2.0MPa), the properties of the asphalt after the reaction (yield, softening point, intermediate phase content, etc.) can be determined to change with the reaction pressure.

[0064] The reaction generally starts at 390°C and ends at 450°C, which is achieved by a temperature control device.

[0065] The above scheme of the present application completes the test process at the same temperature and different reaction times in one test process: asphalt samples of the same mass are placed in a reactor, put into a heating furnace, and the temperature is raised programmatically. After reaching the reaction temperature, the reactor is taken out at different reaction times, and the samples are analyzed. Then, the reaction law of the sample changing with time at a temperature can be obtained in one experiment.

[0066] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, the obvious changes or modifications derived therefrom are still within the scope of protection of this application.
