Description

Technical Field

[0001] The present application relates to the field of tail gas treatment, and in particular to an asphalt tail gas treatment system. Background Art

[0002] Asphalt exhaust is produced during the asphalt production process. Asphalt exhaust may contain various dispersed particles such as suspended fine particulate matter, solid hydrocarbon particles, gaseous hydrocarbon derivatives and carcinogens. If the asphalt exhaust is directly discharged into the atmosphere, it will seriously pollute the surrounding environment and endanger human health. Therefore, the dispersed particles in the asphalt smoke need to be separated and filtered to an acceptable level before the purified gas can be discharged.

[0003] When purifying asphalt tail gas, high-temperature spraying can be used to combine most of the dispersed particles in the asphalt tail gas with the high-temperature water mist to form larger water droplets that then settle. However, asphalt tail gas itself has a certain amount of heat, which will be dissipated during the treatment process, resulting in energy waste. Summary of the Invention

[0007] By adopting the above technical solution, the asphalt exhaust gas first enters the water tank through the smoke inlet pipe. The water tank has a first water storage chamber, and the first smoke guide pipe is arranged in the first water storage chamber. When the asphalt exhaust gas passes through the first smoke guide pipe of the first water storage chamber, the heat is transferred from the high-temperature asphalt exhaust gas to the low-temperature water in the first water storage tank through the pipe wall of the first smoke guide pipe by heat conduction. The heat of the asphalt exhaust gas is utilized by the heat transfer to reduce energy waste.

[0009] By adopting the above technical solution, if the asphalt exhaust gas enters from the lower part of the purification tank and the steam is above, this will cause part of the steam to be discharged through the upper part of the purification tank before mixing with the asphalt exhaust gas, thereby resulting in waste of steam. Therefore, a smoke guide plate is provided in the purification tank, and a second smoke guide pipe is provided on the smoke guide plate. The position of the second smoke guide pipe in the vertical direction corresponds to the position of the steam port, so that the steam port can directly mix with the asphalt exhaust gas after coming out of the air guide pipe, thereby improving the mixing efficiency of the two, so as to improve the purification effect of the diffused molecules in the asphalt exhaust gas.

[0013] By adopting the above technical solution, when the asphalt exhaust gas enters the first cavity, it will first enter the first sliding cavity and force the first piston to move upward, thereby driving the smoke guide plate to move upward to a position corresponding to the steam port, and the smoke guide plate can force the first closing plate to open the first connecting hole through the opening component during the upward sliding process. At this time, the first connecting hole corresponds to the second connecting hole, and the asphalt exhaust gas in the first cavity can enter the interior of the smoke guide plate.

The water tank has a first water storage chamber, and the first smoke guide pipe is arranged in the first water storage chamber. When the asphalt tail gas passes through the first smoke guide pipe of the first water storage chamber, heat is transferred from the high-temperature asphalt tail gas to the low-temperature water in the first water storage tank through the pipe wall of the first smoke guide pipe by heat conduction. The heat of the asphalt tail gas is utilized through the heat transfer, reducing energy waste. The asphalt tail gas then passes through the electrostatic oil collector to separate the tar from the asphalt flue gas, and then is processed by the high-voltage electrolyzer.

[0025] If the asphalt exhaust gas enters from the lower part of the purification tank and the steam is above, some of the steam will be discharged through the upper part of the purification tank before it is mixed with the asphalt exhaust gas, resulting in waste of steam.

A third sliding cavity 571 is vertically defined in the inner wall of the purification tank 5. The first closing plate 57 is vertically slidably connected to the third sliding cavity 571. The smoke guide plate 8 is provided with an opening assembly 83. When the smoke guide plate 8 moves to a position where the second smoke guide tube 88 is vertically aligned with the position of the steam outlet 551, the opening assembly 83 forces the first closing plate 57 to open the first connecting hole 531, thereby connecting the first connecting hole 531 with the second connecting hole 821.

[0051] The first closing plate 57 defines an insertion hole 572 for inserting the insertion plate 832. The wall of the second cavity 54 defines a first avoidance groove 573 for accommodating the insertion plate 832. The length of the first avoidance groove 573 is vertically arranged, so that the insertion plate 832 can always be inserted into the insertion hole 572 during the upward sliding process. A guide surface 833 is provided on the lower side of the insertion plate 832 near one end of the first closing plate 57. The guide surface 833 is inclined from top to bottom, away from the first closing plate 57.

The two ends of the first push rod 593 are respectively connected to the first piston 592 and the lower surface of the connecting block 82. By ventilating the lower part of the first sliding chamber 594, the first piston 592 can be driven to move upward, thereby forcing the smoke guide plate 8 to move upward.

[0054] Reference Figure 2 and Figure 8 The first cavity 53 has a fourth connecting hole 535 located below the first connecting hole 531, which is connected to the lower portion of the first sliding cavity 594. A one-way valve 536 is located in the middle of the fourth connecting hole 535, allowing gas to enter the first sliding cavity 594 only from the first cavity 53. A vent hole 537 is defined in the sidewall of the first sliding cavity 594, located below the second piston 562. This vent hole 537 is located above the fourth connecting hole 535 and is connected to the first cavity 53. A second sliding groove 538 is defined in the wall of the first cavity 53.

The second closing plate 595 has a waist-shaped groove 596 defined therein. A connecting rod is fixedly connected to the lower end of the second closing plate 595. The connecting rod is fixedly connected to the side of the movable plug 533 away from the third connecting hole 532.

[0055] The waist-shaped groove 596 is always connected to the fourth connecting hole 535. When the second piston 562 slides upward, the waist-shaped groove 596 and the air leakage hole 537 are staggered, so that the second closing plate 595 can close the air leakage hole 537. When the water level inside the heating box 51 drops, the movable plug 533 closes the third connecting hole 532, thereby driving the second closing plate 595 to move upward, so that the waist-shaped groove 596 is connected to the air leakage hole 537 to relieve the first sliding cavity 594, so that the first piston 592 can move downward under the action of gravity and drive the smoke guide plate 8 to move downward, thereby cleaning the second smoke guide pipe 88.

[0056] Reference Figure 2 、 Figure 4 and Figure 9 The smoke guide plate 8 is provided with a second drive assembly 9 that drives the second smoke guide tube 88 to rotate. When the smoke guide plate 8 slides downward, the second drive assembly 9 drives the second smoke guide tube 88 to rotate. The second drive assembly 9 includes a first rotating roller 91, a connecting rope 92, and a torsion spring 93. A first mounting slot 84 is defined within the smoke guide plate 8. The first rotating roller 91 is positioned within the first mounting slot 84, with the axis of the first rotating roller 91 parallel to the length of the first mounting slot 84. The torsion spring 93 is sleeved on one end of the first rotating roller 91. The ends of the torsion spring 93 are respectively fixedly connected to the outer circumferential wall of the first rotating roller 91 and the wall of the first mounting slot 84. The upper end of the connecting rope 92 is fixedly connected to the outer circumferential wall of the first rotating roller 91. The lower end of the connecting rope 92 passes through the smoke guide plate 8 and is fixedly connected to the wall of the second cavity 54 via the connecting plate. When the smoke guide plate 8 moves downward, the first rotating roller 91 reels the connecting rope 92 . When the smoke guide plate 8 moves upward, the connecting rope 92 unwinds and forces the first rotating roller 91 to rotate, so that the torsion spring 93 has elastic potential energy.

[0057] The second drive assembly 9 also includes a first gear 94, a first gear ring 95, a bevel gear ring 96, and a bevel gear 97. A second mounting slot 85 is defined at the bottom of the smoke guide plate 8. The axis of the second mounting slot 85 is coaxial with the axis of the smoke guide plate 8. The first gear ring 95 and the first gear 94 are both located within the second mounting slot 85. The lower end of the second smoke guide tube 88 extends into the second mounting slot 85. A plurality of first gears 94 are provided, each corresponding to a plurality of second smoke guide tubes 88. The first gear 94 is coaxially fixedly connected to the lower end of the second smoke guide tube 88 and meshes with the first gear ring 95. Rotation of the first gear ring 95 drives the second smoke guide tube 88 to rotate as well.

[0058] A third mounting slot 86 is defined above the second mounting slot 85. A bevel gear ring 96 is positioned within the third mounting slot 86 and fixedly connected to the upper surface of the first gear ring 95. A fourth mounting slot 87 is defined on the side of the third mounting slot 86 adjacent to the first mounting slot 84. The end of the first rotating roller 91, distal from the torsion spring 93, is pivotally inserted into the fourth mounting slot 87. A bevel gear 97 is coaxially positioned within the fourth mounting slot 87 and coaxially fixedly connected to the first rotating roller 91. The bevel gear 97 meshes with the bevel gear ring 96.

[0059] The implementation principle of an asphalt exhaust treatment system in an embodiment of the present application is as follows: when the purification tank 5 is not working, the smoke guide pipe is located at the bottom of the sliding position. When the asphalt exhaust enters the first cavity 53, the first connecting hole 531 is closed by the first closing plate 57 at this time, so the asphalt exhaust will first enter the first drive box 591, thereby forcing the first piston 592 to move upward to drive the smoke guide plate 8 to move upward.

[0060] After smoke guide plate 8 moves upward to a certain position, insertion plate 832 is inserted into insertion hole 572, driving first closing plate 57 to open first connecting hole 531. Asphalt exhaust gas then enters smoke guide plate 8 and exits through first through hole 881, mixing with the steam at steam outlet 551. As smoke guide plate 8 moves upward, connecting rope 92 is pulled, driving first rotating roller 91 to rotate, imparting elastic potential energy to torsion spring 93.

[0061] When the water level in the water tank 7 drops to a certain level, it drives the second piston 562 downward, causing the movable plug 533 to close the third connecting hole 532. The movement of the movable plug 533 drives the second closing plate 595 to move, opening the vent hole 537 and allowing the first drive box 591 to release air. At this point, the smoke guide plate 8 moves downward under the action of the torsion spring 93 and gravity. During this movement, the second smoke guide pipe 88 is driven to rotate by the first gear 94. The second smoke guide pipe 88 passes through the cleaning hole 581 to clean the outer wall. When the water level reaches a certain level, the third connecting hole 532 is reopened, forcing the smoke guide plate 8 to move upward again.

[0062] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
