Description

Technical Field

[0001] This utility model belongs to the technical field of asphalt recycling equipment, specifically relating to a high-performance asphalt recycling system. Background Technology

[0002] During long-term service, asphalt pavements undergo oxidative aging due to the influence of sunlight, oxygen, temperature changes, and traffic loads. This leads to a decrease in the light components (saturated and aromatic components) and an increase in the heavy components (colloids and asphaltenes) in the asphalt, resulting in hardening, embrittlement, and decreased crack resistance, ultimately leading to defects such as cracks and loosening. To extend the service life of asphalt pavements and reduce resource consumption, asphalt recycling agents are typically applied to aged asphalt pavements to restore their performance.

[0003] In existing technologies, permeability is a crucial indicator of the high performance of asphalt rejuvenators, directly impacting other properties (strong repair properties, low viscosity and high fluidity, low-temperature crack resistance, and long-term anti-aging properties). However, in actual preparation, impurities (metal fragments, dust, etc.) exist in the base oil. These impurities are often overlooked due to their small particle size. Furthermore, catalyst residues and micro-agglomerates of modifiers from micro-reactions may also be present during preparation. During subsequent use, these impurities can clog micropores in the road surface, thus reducing permeability. Moreover, the amount of penetration accelerator added to the base oil in asphalt rejuvenators is typically determined according to a set ratio. However, variations in base oil batches and losses of penetration accelerators during subsequent reactions can lead to a decrease in the actual concentration of the penetration accelerator, affecting the final permeability of the asphalt rejuvenator. Additionally, during preparation, penetration accelerators, modifiers, and anti-aging agents are usually directly mixed and modified simultaneously, or added in batches for mixed modification. If they are added at the same time, the surface tension of the base oil is high, which will make it difficult for the modifier to disperse due to excessive interfacial tension. This requires a long stirring time and is prone to polymerization. Adding them in batches will inevitably prolong the stirring time. Utility Model Content

[0015] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] Please see Figure 1The present invention provides a high-performance asphalt rejuvenator preparation system. The system includes a pretreatment blending tank 10, a reaction vessel 20, a purification unit 30, a permeability control tank 40, and a corresponding controller. The pretreatment blending tank 10 is connected to a base oil supply unit 60 and a first permeability accelerator supply unit 70. The reaction vessel 20 is connected to the pretreatment blending tank 10 and is connected to a modifier supply unit 80 and an anti-aging agent supply unit 90. The reaction vessel 20 can mix and modify the blended liquid discharged from the pretreatment blending tank 10 with the added modifier and anti-aging agent. The purification unit 30 is connected to the reaction vessel 20 and can filter and purify the modified liquid discharged from the reaction vessel 20. Multiple permeability control units are provided, each connected to the purification unit 30, and each unit can sequentially receive the purified modified liquid discharged from the purification unit 30. Each permeability control unit can temporarily store the received purified and modified liquid and, after permeability testing, export it or adjust it by adding a permeability enhancer.

[0017] The asphalt high-performance rejuvenator preparation system provided in this embodiment, compared with the prior art, has a pretreatment blending tank 10 connected to a base oil supply unit 60 and a first penetration accelerator supply unit 70. This allows for the preferential injection of penetration accelerators into the base oil, ensuring sufficient diffusion and effectively reducing the surface tension and viscosity of the base oil. The mixture is then introduced into the reactor 20, reducing the mixing time in the reactor 20, preventing polymerization, and improving production efficiency. The purification unit 30, located downstream of the reactor 20, ensures the removal of impurities from the formed modified liquid, preventing blockages that could affect the penetration effect. Multiple penetration performance control units, located downstream of the purification unit 30, ensure the sequential reception of the purified modified liquid, guaranteeing continuous production at the front end. These units also facilitate permeability testing and allow for the replenishment of penetration accelerators if the permeability test fails, further adjusting the permeability to ensure the final product's permeability.

[0018] In addition, since the mixing in the pretreatment mixing tank 10 and the mixing and modification in the reaction vessel 20 are carried out in steps, the mixing work of the next batch can be carried out in the pretreatment mixing tank 10 during the mixing and modification process in the reaction vessel 20. This method can effectively improve the preparation efficiency.

[0019] In this embodiment, please refer to Figure 1The first permeation accelerator supply unit 70 may include a permeation accelerator storage tank and a metering pump. The permeation accelerator in the storage tank may be fatty alcohol polyoxyethylene ether, light aromatic oil, etc. The permeation accelerator storage tank is connected to the pretreatment blending tank 10 via a pipeline, and a metering pump is installed on the pipeline to ensure that a fixed amount of permeation accelerator is added according to the amount of base oil added, specifically, the permeation accelerator accounts for 5%-8% of the base oil content.

[0020] As one possible implementation method in this embodiment, the base oil supply unit 60 may include a base oil storage tank. The base oil in the storage tank may be C8-C12 light naphthenic oil or hydrotreated waste lubricating oil, etc. The base oil storage tank is connected to the pretreatment blending tank 10 via a pipeline, and a metering pump is installed on the pipeline. In addition, a vacuum deep dehydration tank may be added between the base oil storage tank and the pretreatment blending tank 10 to remove water from the base oil. The vacuum deep dehydration tank is prior art and will not be described in detail here.

[0021] In some embodiments, the above-mentioned reactor 20 may be adopted as follows: Figure 2 The structure shown. See also Figure 2 The reaction vessel 20 includes a first tank body 21 and a first stirring structure 22. The first tank body 21 has a reaction chamber. The top of the first tank body 21 is provided with a first inlet 24 connected to the pretreatment mixing tank 10, a second inlet 25 connected to the modifier supply unit 80, and a third inlet 26 connected to the anti-aging agent supply unit 90. The bottom of the first tank body 21 is provided with a discharge port 27 connected to the purification unit 30. The outer wall of the first tank body 21 is provided with a first jacket 23 capable of providing heat. The first stirring structure 22 is disposed on the first tank body 21 and has a first stirring part extending into the first tank body 21.

[0022] The reactor 20 receives the blended liquid from the pretreatment mixing tank 10. Because the blended liquid is preferentially mixed, its viscosity decreases, and its flowability is enhanced. Upon entering the reaction chamber, it facilitates the dispersion of modifiers and anti-aging agents, improving production efficiency. The reactor 20 can perform modification at a low temperature of 100-120℃ under a micro-pressure environment of 0.1-0.2 MPa. The micro-pressure environment prevents the volatilization of light components, while low-temperature modification avoids component polymerization and viscosity increases. The first stirring structure 22 ensures thorough mixing of the materials, thereby ensuring the dispersion of modifiers and anti-aging agents in the blended liquid and guaranteeing the effectiveness of the mixing modification.

[0023] The first jacket 23 can be circulated with oil at 100-120℃.

[0024] In this embodiment, the modifier can be a polyether polyol or low molecular weight SBS, accounting for 2%-4% of the base oil mass, and the anti-aging agent can be a phosphite or BHT, accounting for 0.05%-1.5% of the base oil mass. Specifically, the modifier supply unit 80 may include a modifier storage tank and a metering pump. A metered amount of modifier can be delivered to the reactor 20 via the metering pump. The anti-aging agent supply unit 90 may include an anti-aging agent storage tank and a metering pump, which can deliver the anti-aging agent to the reactor 20.

[0025] In this embodiment, the first stirring structure 22 may include a vertical shaft rotatably mounted on the first tank 21 and extending into its interior from the top of the first tank 21. The vertical shaft is provided with stirring blades that can extend and approach the inner wall of the reactor 20, and the top of the first tank 21 is provided with a driver that can be poweredly connected to the top of the vertical shaft. This structure is a conventional configuration and will not be described in detail here.

[0026] In some embodiments, the purification unit 30 described above may employ, for example... Figure 1 The structure shown. See also Figure 1 The purification unit 30 includes a filtration device 31 and an impurity collection tank 32. The filtration device 31 has an inlet connected to the discharge port 27, and also has an impurity outlet and a liquid outlet. The filtration device 31 is capable of filtering impurities in the modified liquid. The impurity collection tank 32 is connected to the impurity outlet and is capable of collecting the filtered impurities.

[0027] The filter ensures that impurities in the modified liquid are filtered out, and the impurity collection tank 32 collects residual impurities, which ensures that impurities in the formed modified liquid are removed and prevents these impurities from affecting the permeation effect due to blockage.

[0028] In some embodiments, the purification unit 30 described above may employ, for example... Figure 1 The structure shown. See also Figure 1 The filter device 31 is a pleated membrane filter or a ceramic membrane filter.

[0029] The pleated membrane filter can be a PP pleated membrane filter or a PTEE pleated membrane filter. These types of membrane filters are existing technologies and can ensure the filtration of even minute impurities, thereby guaranteeing the product's permeability.

[0030] In some embodiments, the purification unit 30 described above may employ, for example... Figure 1 The structure shown. See also Figure 1 The purification unit 30 also includes a vacuum thin-film evaporator 33, which has an inlet connected to the outlet of the filter device 31. It also has a light component outlet and a heavy component outlet, the heavy component outlet being connected to each permeability control tank 40.

[0031] When light components, such as solvents, are involved, these components are prone to volatilization during subsequent use, which can cause blockage of the permeation channels or surface crust formation. The vacuum thin-film evaporator 33 (-0.08~-0.085MPa, 50-60℃) removes volatile light components (such as unreacted small molecule monomers) with boiling points ≤80℃ from the modified liquid, thus preventing the rapid evaporation of the regenerator after application and the formation of a crust layer. The light components can then be reused.

[0032] Regarding the working principle of the vacuum thin-film evaporator 33, by dispersing the modified liquid in the form of a thin film on the heating surface under high vacuum, and utilizing the characteristics of the vacuum environment to lower the boiling point of the liquid and reduce thermal damage, efficient and low-temperature removal of solvent from the modified liquid can be achieved, thereby precisely controlling the concentration of the permeation promoter in the system. The vacuum thin-film evaporator 33 is existing technology and will not be described in detail here.

[0033] In some embodiments, the pretreatment mixing tank 10 described above can be adopted as follows: Figure 3 The structure shown. See also Figure 3 The pretreatment blending tank 10 includes a second tank body 11, a second stirring structure 12, and a viscosity meter 17. The second tank body 11 has a blending chamber. The top of the second tank body 11 is provided with a fourth inlet 14 connected to the base oil supply unit 60 and a fifth inlet 15 connected to the penetration enhancer supply unit. The bottom of the second tank body 11 is provided with a blending liquid outlet 16 connected to the reaction vessel 20. The outer wall of the second tank body 11 is provided with a second jacket 13 capable of providing heat. The second stirring structure 12 is disposed on the second tank body 11 and has a second stirring section extending into the second tank body 11. The viscosity meter 17 is disposed on the second tank body 11 and is capable of monitoring the viscosity of the blending liquid.

[0034] The pretreatment blending tank 10, through the second tank 11 and the second stirring structure 12, can preferentially mix the base oil and the penetration enhancer, ensuring that the penetration enhancer is fully dispersed in the base oil, reducing viscosity and enhancing fluidity. Furthermore, it can be used in conjunction with the reaction vessel 20 for batch processing, improving preparation efficiency. The viscosity meter 17 can detect the viscosity within the second tank 11 to confirm whether the mixing is uniform. The second stirring structure 12 can be configured identically to the first stirring structure 22.

[0035] The second jacket 13 can be circulated with water at 25-35℃.

[0036] In some embodiments, the aforementioned permeability control tank 40 can be adopted as follows: Figure 4 The structure shown. See also Figure 4Each permeation performance control tank 40 includes a third tank body 41 and a third stirring structure 42. The third tank body 41 has an adjustment chamber. The third tank body 41 has a sixth inlet 44 connected to the purification unit 30 and a seventh inlet 45 connected to the second permeation promoter supply unit 71, and also has a sample collection outlet 46 and a finished product outlet 47. The outer wall of the third tank body 41 is provided with a third jacket 43 capable of providing heat. The third stirring structure 42 is disposed on the third tank body 41 and has a third stirring part extending into the third tank body 41.

[0037] The third tank 41 can serve as a carrier for exporting the modified liquid. Due to variations in base oil batches or the removal of light components, some loss of the penetration enhancer may occur. In this case, a portion of the modified liquid can be extracted through the sample collection outlet 46 of the third tank 41 for a penetration test. If the penetration test results indicate that the penetration meets the standard, it can be used directly. If the penetration does not meet the standard, up to 1-2% of the penetration enhancer can be added to the third tank 41 through the second penetration enhancer supply unit 71, and mixed using the third stirring structure 42. The third stirring structure 42 can be configured identically to the first stirring structure 22. The second penetration enhancer supply unit 71 can also be identically configured to the first penetration enhancer unit.

[0038] In this embodiment, the third jacket 43 can be circulated with circulating water at 25-35°C.

[0039] It should be noted that during the initial blending stage, the base oil has already been mixed with the same type of penetration enhancer, and after the low-temperature modification reaction, a stable system has been formed in the modified liquid. The penetration enhancer added in the second stage is of the same type as the enhancer in the initial blending (e.g., both are fatty alcohol polyoxyethylene ethers or light aromatic oils), with similar molecular structures. It has good solubility with the base oil in the modified liquid and is a homogeneous mixture. No high-temperature chemical reaction is required; only physical dispersion is needed to achieve molecular-level homogeneity.

[0040] In some embodiments, the above-described asphalt high-performance rejuvenator preparation system may employ, for example... Figure 1 and Figure 5 The structure shown. See also Figure 1 and Figure 5 The asphalt high-performance recycling agent preparation system further includes a collection unit 50, which comprises a finished product storage tank 51 and a fourth stirring structure 52. The finished product storage tank 51 is connected to the finished product outlet 47 of each of the third tanks 41. The finished product storage tank 51 has a collection chamber and is provided with an eighth inlet 54 and an outlet 55. A fourth jacket 53 capable of providing heat is provided on the outer wall of the finished product storage tank 51. The fourth stirring structure 52 is disposed on the finished product storage tank 51 and has a fourth stirring part extending into the finished product storage tank 51.

[0041] The system involves multiple third tanks 41, each capable of holding multiple batches of modified liquid. However, given the continuous front-end reaction and the slow speed of subsequent permeability testing, the third tanks 41 may experience shortages. The finished product storage tank 51, on the other hand, ensures the collection and storage of the modified liquid that has been properly prepared in the third tanks 41, facilitating its direct use later.

[0042] The fourth stirring structure 52 in the finished product storage tank 51 can ensure the stirring of the modified liquid. It can be intermittent stirring to avoid stratification. The fourth stirring structure 52 can be set up with the same structure as the first stirring structure 22.

[0043] In addition, the fourth jacket 53 can be circulated with water at 25-35℃.

[0044] The asphalt high-performance recycling agent preparation system provided in this embodiment is interconnected by pipelines. Solenoid valves are installed on the relevant connecting pipelines, and all solenoid valves are electrically connected to the controller. At the same time, the components that need to be controlled, such as metering pumps, are also electrically connected to the controller. This technology is well known to those skilled in the field of chemical preparation based on existing technology, and will not be described in detail here.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
