Description

Technical Field

[0001] The present invention relates to the technical field of asphalt waste gas treatment devices, and in particular to an asphalt waste gas treatment device. Background Art

[0002] When manufacturing asphalt pavement for paving, the sand and gravel are usually dried and heated, and then mixed with hot asphalt and cold mineral powder. The device for heating these materials is collectively called a drying drum (asphalt drying drum). Asphalt drying drums produce waste gas when producing asphalt. The asphalt waste gas mainly includes volatile organic compounds, particulate matter (PM), nitrogen oxides and sulfides. These waste gases are released during the heating and use of asphalt, which is harmful to air quality and health. Control measures include: using low-temperature heating technology to reduce the emission of organic compounds; installing activated carbon adsorption devices or catalytic reduction devices to treat waste gas; using low-volatility or low-sulfur asphalt raw materials to reduce the generation of harmful substances. These methods can effectively reduce the impact of asphalt production and use on the environment and protect the health of workers.

[0003] In the prior art, the most common technology is to first pass the exhaust gas through a spray tower for preliminary particle sedimentation, in which some organic compounds are precipitated by spraying medicine or water, and then the oily substances in the exhaust gas are stripped from the exhaust gas through oil-electric separation equipment. Finally, the treated exhaust gas is cooled and finally purified through a cavity composed of carbon blocks, and then the gas can be discharged to complete the exhaust gas purification operation;

[0004] The above-mentioned prior art contains the following technical problems in actual operation: when the exhaust gas passes through the atomized medicine or clean water in the spray tower, it is discharged from the pipe on one side without completely reacting with the atomized medicine, which reduces the initial sedimentation effect of the spray tower on the exhaust gas and increases the working pressure of the subsequent steps. In addition, the organic compounds and the medicine will react to form agglomerates, which will block the slots in the spray tower when they move downward with their own weight, and block the flowing spray liquid, making it impossible to recycle the spray liquid. As a result, workers are required to regularly clean and maintain the spray tower, increasing the use cost of the spray tower. Summary of the invention

DETAILED DESCRIPTION

[0038] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example

[0040] like Figures 1 to 9As shown, this embodiment proposes an asphalt waste gas treatment device, including a spray tower body 11, the upper end of the spray tower body 11 is fixedly connected to an outlet pipe 12 for transferring the waste gas that has completed the reaction to the next station, the side wall of the middle section of the spray tower body 11 is fixedly connected to an inlet pipe 13 for inputting the waste gas into the spray tower body 11, and the lower side of the spray tower body 11 is fixedly connected to a water outlet pipe 14 for discharging waste water with sediment from the spray tower body 11;

[0041] Multiple groups of sprinkler irrigation equipment are connected between the air outlet pipe 12 and the air inlet pipe 13;

[0042] The sprinkler irrigation equipment includes an atomizer 15 for atomizing the medicine solution, each limit seat 16 is rotatably connected to each atomizer 15, each limit seat 16 is fixedly connected to the inner wall of the spray tower body 11, and multiple groups of atomizers 15 are placed in a ring with the axis of the spray tower body 11 as the center;

[0043] An air oscillation component that cooperates with the sprinkler irrigation equipment to increase the reaction time between the exhaust gas and the atomized medicine solution is connected between the air inlet pipe 13 and the water outlet pipe 14;

[0044] The air oscillation component can oscillate the waste gas entering the spray tower body 11, increase the reaction time and reaction effect of the waste gas and the medicine, so that more particles in the waste gas can be settled through the atomized medicine, so that after the waste gas passing through the spray tower body 11 enters the next process, the working pressure of the next process is reduced, and the movement of the air oscillation component can drive the radiation area of ​​the spray of multiple atomizers 15 to increase the contact area between the atomized medicine and the waste gas, so that the waste gas can rotate and oscillate to quickly separate the large particles in the waste gas, and the leakage block 21 in the air oscillation component limits the upward and downward sliding of the scraper plate 25, and the water droplets condensed by the atomized medicine and the sedimentation reacting with the medicine The sediments all flow down through the discharge chute 211, and some of the sediments will block the discharge chute 211, thereby reducing the recycling of the medicine. Therefore, the up and down sliding of the scraper plate 25 can also perform mechanical actions on the inner wall of the discharge chute 211 through the scraper block 251, so that the sediments attached to or blocked on the discharge chute 211 are driven by the movement of the scraper block 251, so that the medicine flowing down through the discharge chute 211 can be quickly circulated, and the medicine can be smoothly recycled through the circulation pipeline. It only needs to regularly discharge the sediment agglomerates in the spray tower body 11 through the water outlet pipe 14, so that the equipment can be quickly put into use, which reduces the maintenance cost of the equipment due to agglomeration and blockage, and reduces the use cost.

[0045] like Figure 2 to Figure 7 and Fig. 9 As shown, the air oscillation assembly includes a flow leakage block 21 and a protective cover 22, and the flow leakage block 21 is fixedly connected to the spray tower body 11;

[0046] The protective cover 22 is fixedly connected to the bottom wall of the spray tower body 11, the driving column 23 is rotatably connected to the protective cover 22, the driving column 23 is threadedly connected to the transmission sleeve 24, the outer side of the transmission sleeve 24 is fixedly connected to the scraper plate 25, the scraper plate 25 is fixedly connected to the receiving sleeve 26, and the end of the receiving sleeve 26 away from the scraper plate 25 is rotatably connected to the clamping sleeve 27, and the clamping sleeve 27 is clamped with the side of the driving column 23;

[0047] The driving motor 210 is fixedly connected in the protective cover 22, and the driving shaft of the driving motor 210 is fixedly connected to the driving column 23, and the outer side of the positioning sleeve 27 is fixedly connected to the stirring fan 28;

[0048] A buffer assembly is connected to the spray tower body 11 to buffer the exhaust gas in the spray tower body 11 in cooperation with the rotation of the stirring fan 28;

[0049] When the positioning sleeve 27 rotates forward and moves upward:

[0050] The stirring fan 28 moves upward synchronously, and at the same time stirs the exhaust gas below the stirring fan 28, so that the exhaust gas can react and mix with the atomized solution quickly, until the inlet on the upper side of the spray tower body 11 is blocked. Under the stirring of the stirring fan 28, the exhaust gas is further mixed with the atomized solution with the stirring inertia, so that large particles are quickly settled, and the large particles in the exhaust gas are quickly separated from the exhaust gas;

[0051] When the locking sleeve 27 is reversed and moves downward:

[0052] The stirring fan 28 moves downward synchronously and guides the exhaust gas to the lower side, so that the newly input exhaust gas is guided by this force and will not be quickly discharged from the upper exhaust pipe 12. It can also stir the atomized medicine so that the atomized medicine can be better mixed and reacted with the exhaust gas. At the same time, condensed medicine is also attached to the surface of the lower scraper plate 25, so that part of the exhaust gas can react with this part of the medicine, thereby improving the exhaust gas reaction effect. When the exhaust gas that has completely reacted around the exhaust pipe 12 passes through the exhaust pipe 12, it will be quickly discharged under the action of pressure, so that the new and old exhaust gases will not be remixed.

[0053] like Figure 6 to Figure 8 As shown, the locking groove 231 is formed on the driving column 23, the locking block 271 is fixedly connected to the inner wall of the locking sleeve 27, and the locking block 271 abuts against the inner wall of the locking groove 231;

[0054] The rotation of the driving column 23 can drive the locking sleeve 27 to rotate synchronously, and the locking sleeve 27 can move up and down with the receiving sleeve 26, so that the locking sleeve 27 can rotate and move up and down at the same time, so that the stirring fan 28 fixedly connected to the locking sleeve 27 can cooperate with the locking sleeve 27 to work.

[0055] like Figures 4 to 6 As shown, a plurality of discharge grooves 211 are annularly provided on the discharge block 21, a plurality of scraper blocks 251 are annularly fixedly connected to the scraper block 25, and each scraper block 251 abuts against each discharge groove 211;

[0056] The discharge block 21 limits the upward and downward sliding movement of the scraper plate 25, and the water droplets condensed from the atomized medicine and the sediment reacting with the medicine all flow down through the discharge trough 211. Some sediment will block the discharge trough 211, thereby reducing the recycling of the medicine. Therefore, the upward and downward sliding movement of the scraper plate 25 can also mechanically move the inner wall of the discharge trough 211 through the scraper block 251, so that the sediment attached to or blocked on the discharge trough 211 is driven by the movement of the scraper block 251, thereby allowing the medicine flowing down through the discharge trough 211 to circulate quickly.

[0057] like Figure 2 to Figure 5 and Fig. 9 As shown, the buffer assembly includes a support plate 31 and an air sealing plate 37, the support plate 31 is fixedly connected to the outer ring of the spray tower body 11, a plurality of support frames 32 are fixedly connected to the support plate 31, an air storage pipe 33 is fixedly connected to each support frame 32, a plurality of slow air pipes 34 are fixedly connected to the air storage pipe 33, each piston block 35 is slidably connected in each slow air pipe 34, and one end of each slow air pipe 34 away from the air storage pipe 33 is threadedly connected to each air sealing cap 36;

[0058] The ventilation pipe 37 is fixedly connected to the gas storage pipe 33, and one end of the ventilation pipe 37 away from the gas storage pipe 33 is in communication with the spray tower body 11;

[0059] A plurality of limit posts 39 are slidably connected to the air sealing plate 38, the upper end of each limit post 39 is fixedly connected to the inner wall of the spray tower body 11, each return spring 310 is sleeved on each limit post 39, and the two ends of each return spring 310 are respectively in contact with the spray tower body 11 and the air sealing plate 38;

[0060] When the positioning sleeve 27 moves upward, the linkage column 29 drives the air sealing plate 38 to move upward, so that the air sealing plate 38 slides toward the outlet pipe 12, and finally the air sealing block 311 blocks the outlet pipe 12, so that the exhaust gas entering the spray tower body 11 swirls in the spray tower body 11, thereby increasing the reaction time and reaction effect of the atomized medicine on the exhaust gas, and the gas continuously input into the spray tower body 11 will be input into the gas storage pipe 33 through the ventilation pipe 37, thereby reducing the gas pressure in the spray tower body 11, and then as the positioning sleeve 27 moves upward, the linkage column 29 drives the air sealing plate 38 to slide toward the outlet pipe 12, and finally the air sealing block 311 blocks the outlet pipe 12, so that the exhaust gas entering the spray tower body 11 swirls in the spray tower body 11, thereby increasing the reaction time and reaction effect of the atomized medicine on the exhaust gas, and the gas continuously input into the spray tower body 11 will be input into the gas storage pipe 33 through the ventilation pipe 37, thereby reducing the gas pressure in the spray tower body 11, and then When the position sleeve 27 moves downward, the spray tower body 11 and the air outlet pipe 12 are reconnected. Under the action of pressure, part of the exhaust gas that has been completely reacted on one side of the air outlet pipe 12 can be quickly discharged through the air outlet pipe 12. At the same time, the exhaust gas stored in the air storage pipe 33 can flow back into the spray tower body 11 to react with the atomized solution, thereby increasing the reaction time of the exhaust gas and the atomized solution, so that the atomized solution can fully react with the exhaust gas, and then the large particles in the exhaust gas are quickly settled, thereby reducing the working pressure of the subsequent processes.

[0061] like Figure 2 and Figure 3 As shown, the air sealing block 311 is fixedly connected to the air sealing plate 37, and the outer diameter of the air sealing block 311 is the same as the inner diameter of the air outlet pipe 12. When the air sealing plate 37 moves upward, the air outlet pipe 12 can be better blocked by the air sealing block 311. Under the action of the swirl flow, the reaction time of the exhaust gas in the spray tower body 11 and the atomized medicine is increased, so that the exhaust gas can be more effectively settled, thereby reducing the working pressure of the subsequent processes.

[0062] like Figure 4 As shown, the linkage column 29 is fixedly connected to the locking sleeve 27;

[0063] The linkage disk 41 is rotatably connected to the locking sleeve 27. Preferably, a bearing is fixedly connected between the linkage disk 41 and the locking sleeve 27. The linkage disk 41 is hinged to a plurality of undulating plates 42. One end of each undulating plate 42 away from the linkage disk 41 is hinged to a linkage sleeve 43. Each linkage sleeve 43 is fixedly connected to each atomizer 15.

[0064] The upward movement of the positioning sleeve 27 can drive the linkage disk 41 to move, and the upward movement of the linkage disk 41 causes the angle between the axis of each atomizer 15 and the side wall of the spray tower body 11 to change, thereby adapting to the exhaust gas with different flow rates in the spray tower body 11 for coordinated use, so that the exhaust gas can better react and cooperate with the atomized medicine.

[0065] The principle of this embodiment is:

[0066] The waste gas after asphalt processing is input into the spray tower body 11 through the air inlet pipe 13;

[0067] The driving motor 210 drives the driving column 23 to rotate. Under the mutual sliding action of the discharge block 21 and the scraper block 25, the transmission sleeve 24 threadedly connected with the driving column 23 is driven to move upward. The positioning sleeve 27 can drive the positioning sleeve 27 to move further upward by the rotation action with the receiving sleeve 26. At the same time, the positioning block 271 and the positioning groove 231 are engaged with each other, so that the driving column 23 can drive the positioning sleeve 27 to rotate synchronously, so that the stirring fan 28 can rotate forward as the positioning sleeve 27 moves upward, and reverse as the positioning sleeve 27 moves downward;

[0068] When the positioning sleeve 27 rotates forward and moves upward:

[0069] The stirring fan 28 moves upward synchronously, and at the same time stirs the exhaust gas below the stirring fan 28, so that the exhaust gas can react and mix with the atomized solution quickly, until the inlet on the upper side of the spray tower body 11 is blocked. Under the stirring of the stirring fan 28, the exhaust gas is further mixed with the atomized solution with the stirring inertia, so that large particles are quickly settled, and the large particles in the exhaust gas are quickly separated from the exhaust gas;

[0070] When the locking sleeve 27 is reversed and moves downward:

[0071] The stirring fan 28 moves downward synchronously and guides the exhaust gas to the lower side, so that the newly input exhaust gas is guided by this force and will not be quickly discharged from the upper exhaust pipe 12, and can stir the atomized medicine so that the atomized medicine can be better mixed and reacted with the exhaust gas. At the same time, condensed medicine is also attached to the surface of the lower scraper plate 25, so that part of the exhaust gas can react with this part of the medicine, thereby improving the exhaust gas reaction effect. When the exhaust gas that has completely reacted around the exhaust pipe 12 is connected to the exhaust pipe 12, it will be quickly discharged under the action of pressure, so that the new and old exhaust gases will not be mixed again.

[0072] When the positioning sleeve 27 moves upward, the air sealing plate 38 is driven to move upward through the linkage column 29, so that the air sealing plate 38 slides toward the direction of the air outlet pipe 12, and the air sealing plate 38 changes the simultaneous atomization radiation area of ​​the multiple atomizers 15, so that the exhaust gas can better react with the atomized liquid in the guide, and finally the air sealing block 311 blocks the air outlet pipe 12, and finally the air sealing block 311 blocks the air outlet pipe 12, so that the exhaust gas entering the spray tower body 11 swirls in the spray tower body 11, and the atomized liquid is sprayed upward at this time, so as to increase the reaction time and reaction effect of the atomized liquid on the exhaust gas, and the gas continuously input into the spray tower body 11 will be input into the gas storage pipe 33 through the ventilation pipe 37, thereby reducing the spray tower body 1 1, the atomized liquid settles downward from the uppermost side, and then slowly reacts with the waste gas in the lower layer, so that before the positioning sleeve 27 moves downward, the reaction effect of the waste gas in the upper layer will be better than that of the waste gas in the lower layer, and then as the positioning sleeve 27 moves downward, the spray tower body 11 and the air outlet pipe 12 are re-connected. Under the action of pressure, part of the waste gas that has been completely reacted on one side of the air outlet pipe 12 can be quickly discharged through the air outlet pipe 12, and at the same time, the waste gas stored in the air storage pipe 33 can flow back into the spray tower body 11 to react with the atomized liquid, which increases the reaction time of the waste gas and the atomized liquid, so that the atomized liquid can fully react with the waste gas, and then the large particles in the waste gas are quickly settled, thereby reducing the working pressure of the subsequent processes.

[0073] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
