Tail gas treatment device based on modified asphalt production

Abstract

This invention discloses a tail gas treatment device based on modified asphalt production, belonging to the field of environmental engineering construction technology. It includes a spray tower, an electrostatic precipitator, and a purification tower. The spray tower has two sets of reciprocating rotating mechanisms inside, each including a built-in ring frame. The tail gas treatment device disclosed in this invention, after a period of use, activates a rotary motor to drive a contact push rod on a rotating rod to contact a mating plate below the packing layer. The rotary motor rotates continuously by 90°, causing a sliding block to compress a reciprocating spring.

Description

Technical Field

[0001] This invention relates to the field of environmental engineering construction technology, and in particular to a tail gas treatment device based on modified asphalt production. Background Technology

[0002] During the production of modified asphalt, the high-temperature stirring and reaction stages generate a large amount of exhaust gas containing asphalt fumes, volatile organic compounds (VOCs), particulate matter, and malodorous gases. This exhaust gas has a complex composition, high temperature, and strong adhesion. If it is directly emitted without effective treatment, it will cause serious pollution to the atmospheric environment and the surrounding ecology. With the continuous improvement of environmental protection engineering construction and ecological protection engineering construction standards, traditional single treatment methods are no longer able to meet the increasingly stringent emission requirements. In recent years, high-efficiency activated carbon has been widely used in the field of exhaust gas purification due to its advantages such as large specific surface area, strong adsorption capacity, and good regeneration performance. It can significantly improve the removal efficiency of organic matter and odor substances.

[0003] Existing exhaust gas treatment devices use alkaline solutions to spray the exhaust gas during pretreatment. The spray tower requires a packing layer. During use, tar-like sticky substances and dust particles carried in the exhaust gas can clog the packing layer. Simple high-pressure washing cannot effectively remove the blockages in the packing layer, resulting in a decrease in the gas-liquid throughput of the packing layer and a reduction in exhaust gas treatment efficiency and effect.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] The exhaust gas treatment device disclosed in this invention, based on modified asphalt production, is mainly applied to existing exhaust gas treatment devices that use alkaline solution to spray exhaust gas during pretreatment. The spray tower requires a packing layer. During the use of the packing layer, tar-like sticky substances and dust particles carried in the exhaust gas can cause blockage of the packing layer. Simple high-pressure washing cannot effectively remove the blockage in the packing layer, resulting in a decrease in the gas-liquid throughput of the packing layer and a reduction in exhaust gas treatment efficiency and effect.

[0030] Reference Figures 1-11A tail gas treatment device based on modified asphalt production includes a spray tower 1, an electrostatic precipitator 5, and a purification tower 6. The spray tower 1 has two sets of reciprocating rotating mechanisms 16 inside, each including an internal ring frame 1601 fixedly connected to the inner wall of the spray tower 1. An annular limiting rail 1603 is fixedly connected to the inner wall of the internal ring frame 1601 near its bottom end. A movable slider 1613 is slidably connected inside the annular limiting rail 1603. A fixed block 1612 is fixedly connected to the annular limiting rail 1603 away from the movable slider 1613. A reciprocating spring 1611 is fixedly connected between the movable slider 1613 and the fixed block 1612. A packing layer 12 is fixedly connected to the outer wall of the movable slider 1613, and a guide ring plate 1602 is fixedly connected to the top of the packing layer 12. A fixed rod 1607 is fixedly connected inside the annular limiting rail 1603, and a motor base 1608 is fixedly connected to the end of the fixed rod 1607. A rotary motor 1609 is fixedly connected to the top of the motor base 1608. A rotary shaft is fixedly connected to the output shaft of the rotary motor 1609 through a coupling. A rotating rod 1605 is fixedly connected to the outer wall of the rotating shaft. A hydraulic cylinder 1615 is fixedly connected to the bottom of the rotating rod 1605 away from the rotary motor 1609. A contact push rod 1618 is fixedly connected to the output end of the hydraulic cylinder 1615. A mating plate 1604 is fixedly connected to the bottom of the packing layer 12 near the bottom of the contact push rod 1618. The mating plate 1604 is in contact with the contact push rod 1618. A guide plate 1610 is fixedly connected to the outer wall of the rotating shaft below the rotating rod 1605.

[0031] In specific application scenarios, after the packing layer 12 has been used for a period of time, the rotary motor 1609 is started to drive the contact push rod 1618 on the rotating rod 1605 to contact the mating plate 1604 below the packing layer 12. The rotary motor 1609 rotates continuously by 90°, and the moving slider 1613 squeezes the reciprocating spring 1611. The adjusting hydraulic cylinder 1615 drives the contact push rod 1618 to descend, and the contact push rod 1618 separates from the mating plate 1604. The reciprocating spring 1611 resets, causing the packing layer 12 to be in an irregular reciprocating shaking state, thereby gradually loosening and transferring the blockage in the packing layer 12. With the assistance of the flushing mechanism 17, the blockage is quickly cleared, ensuring smooth gas and liquid flow in the packing layer 12 and improving the exhaust gas treatment efficiency and treatment effect.

[0032] Specifically, after the contact push rod 1618 separates from the mating plate 1604, the rotary motor 1609 drives the rotating rod 1605 to rotate continuously, starting the collection pump 1616. The collection pump 1616 collects the dislodged blockage through the collection hole 1614 on the collection frame 1606 and guides it into the collection frame 1606 to prevent the blockage from mixing with the exhaust gas again and causing secondary blockage of the packing layer 12. At the same time, the liquid entering the collection frame 1606 is discharged through the drain hole 1617.

[0033] Reference Figures 1-6 In a preferred embodiment, a collection frame 1606 is fixedly connected to the top of the rotating rod 1605, and a collection hole 1614 is opened at the top of the collection frame 1606. A collection pump 1616 is fixedly connected to the bottom of the rotating rod 1605. The collection end of the collection pump 1616 is connected to the inside of the collection frame 1606 through a pipe, and the delivery end of the collection pump 1616 is connected to the inside of the collection frame 1606 through a pipe. A drain hole 1617 is opened at the bottom of the collection frame 1606, and the diameter of the drain hole 1617 is smaller than the diameter of the collection hole 1614.

The cooperating flushing mechanism 17 includes a shaft frame 1704, which is fixedly connected to the inner side wall of the spray tower 1.

The output shaft of the drive motor 1715 is fixedly connected to a drive shaft via a coupling. The bottom of the drive shaft is fixedly connected to a connecting ring 1714.

[0035] Specifically, during the operation of the reciprocating rotation mechanism 16, the adjusting push cylinder 1712 drives the lifting arc block 1720 to descend, and the deflection frame 1705 begins to rotate downward. When the drive motor 1715 is on the center line of the spray tower 1, the push cylinder 1712 stops adjusting, the pipe valve 1702 opens, and some liquid enters the collection ring pipe 1701. The drive motor 1715 and the pressure pump 1710 are started. The pressure pump 1710 introduces the liquid into the flushing frame 1717. The drive motor 1715 drives the flushing frame 1717 to rotate, and the liquid is sprayed out from the flushing hole 1718 to flush the packing layer 12 in all directions. This, together with the reciprocating rotation mechanism 16, achieves effective cleaning of the packing layer 12.

[0036] It should be noted that after the flushing mechanism 17 is in operation, the push cylinder 1712 drives the lifting arc block 1720 to push the deflection frame 1705 upward, so that the deflection frame 1705 moves towards the inner wall of the spray tower 1, so as to avoid the flushing mechanism 17 being located in the middle position of the spray tower 1 and causing obstruction and interference.

The top of the purification tower 6 has an exhaust hole, and the inside of the exhaust hole is fixedly connected to an exhaust pipe 8.

[0041] Reference Figure 1 , Figure 9 , Figure 10 and Figure 11 In a preferred embodiment, the assembly mechanism 7 includes a central column 706 and a sealing ring frame 703.

[0042] Specifically, when replacing the activated carbon plate 702, the sealing ring frame 703 is moved upward, separating it from the docking column 704. After the sealing ring frame 703 separates from the sealing frame 701, the sealing frame 701 is opened. At this time, the adjusting lifting cylinder 708 drives the bonding pressure frame 713 downward, causing the deflection pressure plate 711 to gradually deflect towards the inner wall of the bonding pressure frame 713. After the deflection pressure plate 711 is completely separated from the top of the positioning bottom rod 715, the staff can remove the assembly rod 710 and the activated carbon plate 702 around it from the purification tower 6 for replacement, which is convenient and efficient.

The sealing ring frame 703 is sleeved around the sealing frame 701.

[0044] Working principle: During use, before the exhaust gas enters the spray tower 1, the liquid pump 2 is started. The liquid pump 2 introduces the liquid inside the storage tank 3 into the long liquid pipe 14, and then sprays it onto the packing layer 12 through the nozzle 13. After the liquid pump 2 runs for five minutes, the exhaust gas is introduced into the spray tower 1 through the exhaust gas inlet pipe 4. During the rise of the exhaust gas, it comes into full contact with the liquid. After the packing layer 12 has been used for a period of time, the rotary motor 1609 is started to drive the contact push rod 1618 on the rotating rod 1605 to contact the mating plate 1604 below the packing layer 12. If the slider 1613 rotates 90° continuously, it will compress the reciprocating spring 1611. Adjusting the hydraulic cylinder 1615 will cause the contact push rod 1618 to descend, separating it from the mating plate 1604. The reciprocating spring 1611 will then reset, causing the packing layer 12 to vibrate irregularly, gradually loosening and transferring the blockages. Adjusting the push cylinder 1712 will cause the lifting arc block 1720 to descend, causing the deflection frame 1705 to begin rotating downwards. When the drive motor 1715 is at the center line of the spray tower 1... Then, the cylinder 1712 is stopped from adjusting, the valve 1702 is opened, and some liquid enters the collection ring pipe 1701. The drive motor 1715 and the pressure pump 1710 are started. The pressure pump 1710 guides the liquid into the flushing frame 1717. The drive motor 1715 drives the flushing frame 1717 to rotate, and the liquid is sprayed out from the flushing hole 1718 to flush the packing layer 12 in all directions. During the flushing process, the rotary motor 1609 drives the rotating rod 1605 to rotate continuously. The collection pump 1616 is started. 16. Collect the dislodged blockage through the collection hole 1614 on the collection frame 1606 and guide it into the collection frame 1606 to complete a single cleaning of the packing layer 12. After the exhaust gas comes into full contact with the liquid, it passes through the dehumidification layer 11 and enters the guide pipe 10, and then enters the electrostatic precipitator 5.
