Description

Technical Field

[0001] This invention belongs to the field of waste gas treatment technology, specifically a modified asphalt waste gas treatment device and method. Background Technology

[0002] The production and use of modified asphalt generate waste gas containing harmful substances such as benzo[a]pyrene, polycyclic aromatic hydrocarbons, dust, and volatile organic compounds (VOCs). If this waste gas is emitted directly without effective treatment, it will not only cause serious air pollution but also harm human health. Existing waste gas treatment devices are mostly single-function and lack the ability to achieve synergistic and efficient treatment of multiple pollutants. Furthermore, they are insufficient in terms of equipment integration and intelligence, failing to meet increasingly stringent environmental protection requirements.

[0003] Patent application number CN202510179569.7 discloses a modified asphalt waste gas treatment device and method, which solves the problem that small impurities still exist in the filtered waste gas, making it impossible to effectively collect and treat the impurities. The device includes a separation box, inside which a support hopper is fixedly connected. The support hopper is a hollow structure with openings at both the top and bottom. An air inlet pipe is fixedly connected to the bottom of the support hopper, with the end of the air inlet pipe furthest from the support hopper located outside the separation box. A filter screen is installed above the support hopper. The separation box is equipped with a rotating spray assembly located above the filter screen and an impurity-shaking structure for driving the filter screen to vibrate. This method can remove residual impurities from the filtered waste gas, effectively collecting and treating impurities in the waste gas produced in modified asphalt experiments, reducing pollution to the laboratory environment. It also allows for easy cleaning of the filter screen. While the above solution improves particulate matter removal efficiency through rotating spray and filter screen vibration, it does not involve the graded treatment of organic waste gas and lacks a dynamic response mechanism for waste gas temperature and concentration.

[0004] Because modified asphalt exhaust gas has a complex composition, the elimination efficiency is often insufficient to meet the exhaust gas generation efficiency during the exhaust gas treatment process. This results in problems such as low efficiency, high energy consumption, and delayed operation and maintenance during exhaust gas treatment, which fail to meet environmental protection requirements.

[0005] Therefore, in order to solve the above-mentioned technical problems, the present invention proposes a modified asphalt waste gas treatment device and method. Summary of the Invention

[0006] The purpose of this invention is to address the above-mentioned problems. This invention provides a modified asphalt waste gas treatment device and method, which has the advantages of fully treating modified asphalt waste gas and using different purification methods according to different concentrations of waste gas.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a modified asphalt waste gas treatment device, comprising a support assembly, an air supply assembly connected to the support assembly, a transmission pipe connected to one end of the air supply assembly, a cooling assembly connected to the end of the transmission pipe away from the air supply assembly, a purification assembly connected to one side of the cooling assembly via a pipe, a detection assembly connected to one side of the purification assembly via a pipe, a removal assembly connected to one side of the detection assembly via a pipe, and the removal assembly and the purification assembly connected via a pipe.

[0008] The removal assembly includes a treatment tank, which has a treatment chamber. A return gas pipe and a gas supply pipe are respectively passed through the wall of the treatment chamber. An adsorption plate, a baffle, and an incineration section are respectively connected inside the treatment chamber. A partition plate for dividing the space between the adsorption plate and the baffle is connected to one end of the baffle near the adsorption plate.

[0009] Preferably, the air supply assembly includes an air supply pipe, one end of which is connected to the exhaust gas source, and the other end of which is sealed to a gas storage pipe. The gas storage pipe includes a housing, one end of which is connected to a telescopic part, and a communicating cavity is opened inside the housing. A movable plug is connected to the side of the communicating cavity near the telescopic part, and the transmission pipe is connected to the communicating cavity.

[0010] Preferably, the cooling assembly includes a cooling tank, an air inlet chamber is provided inside the cooling tank, an air inlet is provided through one end of the air inlet chamber and is connected to the transmission pipe, a water outlet is provided through the side of the air inlet chamber away from the air inlet, and a water return section is connected to the end of the water outlet away from the cooling tank.

[0011] Preferably, a fixing plate is connected inside the air intake cavity. The fixing plate is vertically distributed inside the air intake cavity, and the connection position of the fixing plate does not obstruct the position of the air inlet. A filter plate is connected inside the air intake cavity, and spray holes are connected inside the filter plate. The edge of the filter plate contacts the cavity wall of the air intake cavity and the fixing plate respectively. An air outlet pipe is opened on the side of the air intake cavity near the air inlet, and the air outlet pipe is located on the side of the fixing plate away from the filter plate.

[0012] Preferably, the adsorption plate is located on the side of the gas supply pipe near the incineration section, the return gas pipe is located between the adsorption plate and the baffle, and at least two sealing plates are movably provided on the baffle, one of which is located within the coverage area of ​​the enclosure.

[0013] Preferably, the enclosure has a through hole for controlling the switch, and the through hole and the return air pipe are connected through the processing chamber.

[0014] Preferably, a transfer component is connected to one end of the return air pipe away from the treatment tank, and a power unit is connected to the other end of the transfer component. The end of the power unit away from the transfer component is connected to the purification component.

[0015] Preferably, a concentration sensor for monitoring the composition of exhaust gas is connected inside the processing chamber.

[0016] Preferably, the adsorption plate is internally connected to activated carbon for adsorbing waste gas.

[0017] The present invention also includes a waste gas treatment method, which utilizes a modified asphalt waste gas treatment device and includes the following steps:

[0018] S1. Waste gas collection and pressure regulation: Waste gas is introduced into the connecting cavity of the storage pipe through the upper air pipe and stored. The volume of the connecting cavity is adjusted by the telescopic part driving the movable plug. When the amount of waste gas is small, the cavity is compressed to increase the flow rate, and when the amount is large, the cavity is expanded to increase efficiency.

[0019] S2. Exhaust gas cooling and preliminary purification: Exhaust gas enters the air inlet chamber of the cooling component through the transmission pipe, and is cooled by the spray liquid on the filter plate. The liquid flows into the return water section, and the cooled exhaust gas enters the purification component through the air outlet pipe to filter out solid impurities.

[0020] S3. Waste gas composition detection: After purification, the waste gas enters the detection component. The content of solid impurities is detected to determine the efficiency of the purification component, and the concentration of organic waste gas is measured to provide data for the removal component.

[0021] S4. Staged purification treatment: Organic waste gas concentration ≤1000mg / m³ 3 When the incineration unit is not activated, the exhaust gas is adsorbed by the adsorption plates and discharged through the through-holes in the enclosure plate and the return gas pipe; concentration > 1000 mg / m³ 3 When the incineration section is activated, the waste gas is incinerated after being adsorbed, and then discharged through the return gas pipe.

[0022] S5. Verification and circulation of treatment effect: The concentration sensor monitors the exhaust gas. If it meets the standard, it is discharged through the transfer component and power unit; if it does not meet the standard, the adsorption plate is treated in the low concentration mode, and the incineration time is extended in the high concentration mode. The exhaust gas that does not meet the standard is returned to the purification component for secondary treatment.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. Through the collaboration of multiple components, the entire process of waste gas treatment is achieved. The air supply component can dynamically adjust the volume of the gas storage pipe according to the amount of waste gas, and optimize the flow rate and treatment efficiency; the cooling component sprays water to cool down the gas and pre-filters impurities; the detection component combines AI algorithms to monitor the composition of waste gas, predict concentration fluctuations, and adjust the parameters of each component in advance to achieve intelligent prediction and dynamic optimization, thereby improving the overall treatment efficiency.

[0025] 2. The removal components employ a tiered treatment model: low-concentration waste gas is treated solely by activated carbon adsorption, resulting in energy efficiency; high-concentration waste gas is incinerated after adsorption, with the surrounding and enclosed plates controlling the airflow path. Concentration sensors monitor the treatment effect in real time, and waste gas that fails to meet standards can undergo secondary treatment or prompt maintenance, forming a closed-loop feedback to ensure stable and reliable purification.

[0026] 3. Modular design integrates various components, providing a unified installation and maintenance platform to reduce space occupation. Components embed IoT modules, enabling real-time monitoring of operating parameters via the cloud, supporting remote alerts and work order pushes, reducing labor costs through intelligent operation and maintenance, optimizing equipment status through data-driven approaches, extending component lifespan, and improving system reliability.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figures 1-9 As shown, a modified asphalt waste gas treatment device includes a support assembly 1 for fixing and protecting the device. The support assembly 1 includes a canopy to shield the device and a staircase for maintenance of various areas of the device. An air intake assembly 4 for guiding and transmitting waste gas is connected to the support assembly 1. One end of the air intake assembly 4 is connected to a transmission pipe 5 for conveying the waste gas. The end of the transmission pipe 5 away from the air intake assembly 4 is connected to a cooling assembly 2 for reducing the temperature of the waste gas. Therefore, after the waste gas is generated, it is guided through the air intake assembly 4 to the cooling assembly 2 for cooling, facilitating subsequent purification and treatment of the waste gas. The cooling assembly 2... One side of the purification component 6 is connected via a pipe to a purification component 6 for treating floating dust in the cooled exhaust gas. The other side of the purification component 6 is connected via a pipe to a detection component 9 for identifying the pollutant content in the exhaust gas. The purification status of the purification component 6 is judged and identified based on the detection results of the detection component 9, so as to control the purification component 6 in a timely manner. At the same time, the detection component 9 identifies the concentration of organic waste gas in the exhaust gas and controls the removal method of the removal component 3. The other side of the detection component 9 is connected via a pipe to a removal component 3 for eliminating organic waste gas (e.g., RCO). The removal component 3 and the purification component 6 are connected via a pipe.

[0039] In use, the exhaust gas generated by the modified asphalt is first transported by the air supply component 4 and then introduced into the cooling component 2 for cooling through the transmission pipe 5. The cooled gas is then transported to the purification component 6 through the pipeline. After passing through the purification component 6, the gas is introduced into the detection component 9. The detection component 9 identifies the concentration and content of organic waste gas in the exhaust gas. At the same time, the purification status of the purification component 6 is identified based on the detection data of the detection component 9. Finally, the removal method of the removal component 3 is controlled to ensure that the exhaust gas can be effectively treated.

[0040] To ensure effective removal of waste gas of varying concentrations by the detection component 9, the removal component 3 includes a treatment tank 301 for storing and purifying the waste gas. The treatment tank 301 contains a treatment chamber 308 within which the waste gas can move. A return gas pipe 303 for waste gas discharge and a gas delivery pipe 302 for waste gas inlet are respectively installed through the walls of the treatment chamber 308. The return gas pipe 303 and the gas delivery pipe 302 are both connected to the purification component 6. An adsorption plate 305, a baffle 306, and an incineration unit 304 are connected within the treatment chamber 308, and these components do not come into contact with each other. In the treatment chamber 308, the adsorption plate 305, baffle 306, and incineration section 304 are distributed in the following order from bottom to top: incineration section 304, baffle 306, and adsorption plate 305. The adsorption plate 305 can separate the return gas pipe 303 from the incineration section 304. A baffle 306 is connected to a surrounding plate 309 near the adsorption plate 305 to divide the space between the adsorption plate 305 and the baffle 306, ensuring that the waste gas can move along the spatial channel formed by the surrounding plate 309. This ensures that after the waste gas enters the treatment chamber 308 through the gas delivery pipe 302, it can be treated according to the different concentrations in the waste gas.

[0041] When the detection component 9 detects that the concentration of organic waste in the exhaust gas is ≤1000 mg / m³ 3 At this time, the incineration section 304 is not in operation, and there is no need to incinerate the organic waste in the exhaust gas. Therefore, when the exhaust gas enters the treatment chamber 308 through the gas supply pipe 302, the exhaust gas in the treatment chamber 308 directly passes through the adsorption plate 305 to adsorb the waste in the exhaust gas, and then directly exits the treatment chamber 308 through the return gas pipe 303. When the detection component 9 detects that the concentration of organic waste in the exhaust gas is >1000 mg / m³... 3 At this time, the incineration section 304 is in the incineration state, so that the exhaust gas passes through the space constrained by the enclosure plate 309 after passing through the adsorption plate 305, and then passes through the baffle 306 into the space where the incineration section 304 is located for incineration treatment, thereby achieving effective treatment of the exhaust gas, and the incinerated exhaust gas is discharged through the return gas pipe 303.

[0042] Furthermore, to ensure a stable concentration of exhaust gas within the exhaust gas treatment device while maintaining its treatment efficiency, the air intake assembly 4 includes a sealed air intake pipe 401. One end of the air intake pipe 401 is connected to the exhaust gas source, and the other end is sealed to a gas storage pipe 402. Exhaust gas is introduced into the gas storage pipe 402 through the air intake pipe 401. The gas storage pipe 402 includes a housing 4021 for sealing and protection. One end of the housing 4021 is connected to a telescopic part 4022 that can change length. The 21 has a connecting cavity 4023, through which gas from the upper air pipe 401 can enter and be stored. The exhaust gas is then introduced into the cooling assembly 2 through the transmission pipe 5. A movable plug 4024 is connected to the side of the connecting cavity 4023 near the telescopic part 4022. The surface area of ​​the movable plug 4024 is the same as the cross section of the connecting cavity 4023. Thus, when the telescopic part 4022 moves the movable plug 4024, the volume of space inside the connecting cavity 4023 can be adjusted. The transmission pipe 5 is connected to the connecting cavity 4023.

[0043] When the gas content entering the upper air pipe 401 is too low to meet the moving air pressure of the exhaust gas in the treatment device, the length of the control telescopic part 4022 is extended, and the control movable plug 4024 is moved closer to the upper air pipe 401, reducing the volume of the connecting cavity 4023 and reducing the connecting area between the connecting cavity 4023 and the connecting port of the transmission pipe 5. This increases the initial velocity of the gas when passing through the transmission pipe 5, ensuring that it can enter the cooling assembly 2 through the transmission pipe 5 and avoiding excessive residue of impurities in the exhaust gas in the transmission pipe 5.

[0044] When the gas content entering the upper air pipe 401 is sufficient to meet the moving air pressure in the processing device, the length of the control telescopic part 4022 is shortened, thereby controlling the movable plug 4024 to move away from the upper air pipe 401. This increases the volume of the connecting cavity 4023 and the connection area between the connecting cavity 4023 and the transmission pipe 5, ensuring that the gas can quickly enter the transmission pipe 5 and improving the gas processing efficiency in the processing device.

[0045] Furthermore, lowering the temperature of the exhaust gas is beneficial for subsequent treatment processes, as high-temperature exhaust gas can affect the efficiency of subsequent adsorption, catalysis, and other reactions. It also avoids damage to the equipment caused by high temperatures. Therefore, the cooling component 2 includes a cooling tank 201, which has an air inlet chamber 207. One end of the air inlet chamber 207 has an air inlet 204, which is connected to the transmission pipe 5. This allows the gas to be treated to enter the air inlet chamber 207 through the air inlet 204. The gas entering the cooling tank 201 is cooled by contact with the liquid. A water outlet 202 is provided on the side of the air inlet chamber 207 away from the air inlet 204. The end of the water outlet 202 away from the cooling tank 201 is connected to a water return section 10, thereby transferring the cooling water to the water return section 10 through the water outlet 202.

[0046] Furthermore, to ensure that the cooling assembly 2 can fully treat the exhaust gas entering the intake chamber 207, a fixing plate 206 is connected inside the intake chamber 207 to divide the space within the intake chamber 207. The fixing plate 206 is vertically distributed inside the intake chamber 207, and its connection position does not obstruct the position of the air inlet 204, ensuring that the exhaust gas passing through the air inlet 204 is located on one side of the fixing plate 206, preventing uncooled gas from overflowing. A filter plate 205 is connected inside the intake chamber 207 for gas to pass through. The filter plate 205 has spray holes for cooling the gas, and the edges of the filter plate 205 are respectively connected to... The cavity wall of the air intake chamber 207 is in contact with the fixed plate 206. When the exhaust gas enters the air intake chamber 207 through the air intake port 204, it is cooled by the spray holes when passing through the filter plate 205 to ensure that the exhaust gas temperature is sufficiently reduced. An exhaust pipe 203 for conveying cooling gas is opened on the side of the air intake chamber 207 near the air intake port 204. The exhaust pipe 203 is located on the side of the fixed plate 206 away from the filter plate 205. Then, the exhaust gas after passing through the filter plate 205 is pushed by the gas pressure through the exhaust pipe 203 and enters the purification component 6. The purification component 6 cleans and purifies the floating dust in the exhaust gas to ensure that the floating dust in the exhaust gas will not interfere with the subsequent purification treatment.

[0047] Furthermore, to ensure that the exhaust gas can move within the treatment chamber 308 and to perform corresponding purification treatment according to different concentrations of exhaust gas, the adsorption plate 305 is located on the side of the gas supply pipe 302 near the incineration section 304, so that all exhaust gas passing through the gas supply pipe 302 must pass through the adsorption plate 305 for adsorption. The return gas pipe 303 is located between the adsorption plate 305 and the baffle 306. At least two sealing plates 307 are movably installed on the baffle 306, one of which is located within the coverage area of ​​the surrounding plate 309. By controlling the opening and closing of the two sealing plates 307, the movement path of the exhaust gas in the treatment chamber 308 can be changed. When both sealing plates 307 are in a sealed state, the exhaust gas passes through the adsorption plate 305, then through the surrounding plate 309, and then moves out of the treatment chamber 308 through the return gas pipe 303. When the two sealing plates 307 are opened, the exhaust gas passes through the space formed by the surrounding plate 309, passes through the baffle 306 and comes into contact with the incineration section 304, and then enters the return gas pipe 303 through the sealing plate 307 on the other side and is discharged.

[0048] Furthermore, to ensure that the through holes on the enclosure 309 do not leak when the exhaust gas passes through the enclosure 309, thus affecting the exhaust gas treatment efficiency, the enclosure 309 is provided with through holes that can control the switch. The through holes and the return gas pipe 303 are connected through the treatment chamber 308. When the two sealing plates 307 are in the closed state, the through holes are in the open state. When the two sealing plates 307 are in the open state, the through holes are controlled to close, ensuring the stability of the exhaust gas movement path.

[0049] Furthermore, the end of the return gas pipe 303 away from the treatment tank 301 is connected to a transfer component 8 for gas flow, and the other end of the transfer component 8 is connected to a power unit 7 for replenishing the gas pressure in the device. The end of the power unit 7 away from the transfer component 8 is connected to the purification component 6.

[0050] Furthermore, a concentration sensor for monitoring the composition of exhaust gas is connected inside the processing chamber 308.

[0051] Furthermore, activated carbon for adsorbing waste gas is connected inside the adsorption plate 305. The activated carbon is used to adsorb waste gas with low concentration, thereby reducing the incineration time of the incineration section 304.

[0052] The air intake component 4 is connected to the cooling component 2. The cooling component 2 is connected to the purification component 6 and the return water section 10. The purification component 6 is connected to the power unit 7 and the detection component 9. The detection component 9 is connected to the removal component 3. The removal component 3 is connected to the transfer component 8. Finally, the waste gas is discharged through the transfer component 8 after being identified by the transfer component 8. If the waste gas identified by the transfer component 8 does not meet the emission requirements, the transfer component 8 introduces the waste gas into the purification component 6 for secondary circulation.

[0053] During operation, the exhaust gas generated from modified asphalt is transported by the air intake component 4 and introduced into the cooling component 2 for cooling. Simultaneously, the liquid generated during cooling enters the return water section 10. The gas after cooling enters the purification component 6, where impurities are removed. The exhaust gas then passes through the purification component 6 and enters the detection component 9 for identification. This component assesses the purification efficiency of the purification component 6 and detects the organic matter content in the exhaust gas, thereby adjusting the removal method of the removal component 3. After passing through the detection component 9, the exhaust gas enters the removal component 3 for further treatment. After treatment, the gas passes through the transfer component 8 and is discharged from the device if it meets the requirements. If it fails, it enters the purification component 6 for secondary circulation. The power unit 7 assists in stabilizing the movement path of the exhaust gas within the treatment device.

[0054] A one-way valve is installed in the pipeline between the purification component 6 and the detection component 9 to prevent the circulating exhaust gas from colliding with the newly introduced exhaust gas and to ensure that the airflow direction logic is clear.

[0055] When exhaust gas is generated, it is forced into the upper air pipe 401 and moved and transported within it. Simultaneously, the gas in the upper air pipe 401 moves to the connecting cavity 4023 for storage, and then passes through the transmission pipe 5 to achieve further gas movement. During this movement, the gas pressure in the connecting cavity 4023 is adjusted according to the gas concentration to ensure that all gas in the connecting cavity 4023 can quickly pass through the transmission pipe 5. When the gas concentration in the connecting cavity 4023 is low, the length of the telescopic part 4022 is extended, driving the movable plug 4024. The gas moves within the connecting cavity 4023, compressing the space within it and increasing the gas pressure. This reduces the time the gas takes to pass through the transmission pipe 5. When the gas concentration in the connecting cavity 4023 is high, the length of the telescopic part 4022 is shortened, causing the movable plug 4024 to move and increasing the volume of the space within the connecting cavity 4023. This also increases the area of ​​the connection port with the transmission pipe 5, ensuring the stability of the gas movement and preventing rapid increases or decreases in the gas volume within the treatment device, thus ensuring that the gas can be treated normally.

[0056] When the exhaust gas passes through the transmission pipe 5 and the air inlet 204, it enters the air intake chamber 207 and moves, activating the spray holes in the filter plate 205. This causes the spray holes to release cooling liquid, including but not limited to water, coolant, and other liquids with cooling effects. The gas moves within the air intake chamber 207 and passes through the filter plate 205 to be cooled by the spray holes. The liquid used for cooling falls to the bottom of the air intake chamber 207 and enters the return water section 10 through the pipe. After cooling, the gas enters the air outlet pipe 203 after passing through the air intake chamber 207 and then enters the purification component 6. In the purification component 6, the gas filters and cleans the solid impurities contained in the exhaust gas, reducing the interference of impurities with subsequent components.

[0057] After passing through the purification component 6, the exhaust gas is transported to the detection component 9 via a pipeline. The detection component 9 performs a preliminary identification and judgment of the content in the exhaust gas, and adjusts the working mode of the removal component 3 according to the organic matter content detected by the detection component 9. At the same time, the detection component 9 identifies solid impurities in the exhaust gas to read the purification efficiency of the purification component 6. When a large amount of solid impurities is detected in the detection component 9, it means that the purification efficiency of the purification component 6 has decreased, and the purification component 6 needs to be repaired and adjusted. When a small amount of solid impurities is detected in the detection component 9 or the content is normal, it means that the purification component 6 is at normal purification efficiency.

[0058] After passing through purification component 6, the exhaust gas enters treatment chamber 308 via gas delivery pipe 302. At this point, based on the identification data from detection component 9 and concentration sensor, the removal method of removal component 3 is controlled to ensure that organic matter in the exhaust gas is fully eliminated. When detection component 9 detects that the concentration of organic waste in the exhaust gas is ≤1000mg / m³... 3 At this time, the incineration section 304 is not open, and the sealing plates 307 are all closed, so there is no need to incinerate the organic waste in the exhaust gas. Then, when the exhaust gas enters the treatment chamber 308 through the gas supply pipe 302, the waste in the exhaust gas is adsorbed by the adsorption plate 305 and then passes through the through holes on the enclosure plate 309, allowing the exhaust gas to be discharged from the treatment chamber 308 through the return gas pipe 303. When the detection component 9 detects that the concentration of organic waste in the exhaust gas is >1000 mg / m³... 3At this time, the incineration section 304 is in the incineration state, and the through hole on the enclosure plate 309 is closed while the sealing plate 307 is opened, so that the exhaust gas can pass through the baffle 306 and come into contact with the incineration section 304. After passing through the adsorption plate 305, the exhaust gas passes through the space constrained by the enclosure plate 309 and then passes through the baffle 306 into the space where the incineration section 304 is located for incineration treatment, thereby achieving effective treatment of the exhaust gas. The incinerated exhaust gas is then discharged through the return gas pipe 303. During the discharge process through the return gas pipe 303, the concentration sensor is used to identify and analyze the components of the treated exhaust gas to ensure the stable removal efficiency of the removal component 3.

[0059] Furthermore, during the identification process by the concentration sensor, when the concentration sensor detects that the treated waste gas meets the emission standards, the removal method and removal force of the removal component 3 remain unchanged. When the concentration sensor detects that the treated waste gas does not meet the emission standards, if the waste gas is only purified by the adsorption plate 305, it means that the adsorption efficiency of the adsorption plate 305 decreases and cannot meet the treatment of organic matter in the waste gas. The adsorption plate 305 needs to be cleaned or replaced in time. If the waste gas passes through the incineration section 304 after passing through the adsorption plate 305, it means that the waste gas is not fully incinerated by the incineration section 304. The opening of the closed plate 307 inside the control plate 309 remains unchanged, and the opening area of ​​the closed plate 307 outside the control plate 309 is reduced to increase the residence time of the waste gas in the incineration section 304, so that the organic matter in the waste gas can be fully burned by the incineration section 304.

[0060] After passing through the return gas pipe 303, the exhaust gas is discharged from the device after being identified as qualified by the transfer component 8. If it is not qualified, it enters the purification component 6 for secondary circulation treatment. The power unit 7 can help stabilize the movement path of the exhaust gas in the treatment device.

[0061] Meanwhile, IoT modules are embedded in the detection component 9, air supply component 4, cooling component 2, and removal component 3 to achieve real-time data interaction via 5G or industrial Ethernet. A control center is added to the detection component 9, and the concentration sensor integrates AI algorithms, which can not only detect the composition of exhaust gas, but also predict the trend of exhaust gas concentration fluctuations through historical data.

[0062] For example, when it is predicted that the exhaust gas volume will surge within the next half hour, a pre-expansion command is issued to the upper air assembly (4) in advance (that is, the movable plug 4024 is moved by the telescopic part 4022 to adjust the volume inside the connecting cavity 4023 in advance), and the spray liquid reserve is preloaded into the cooling assembly 2 to avoid processing delay.

[0063] The operating parameters of each component (such as the displacement of the telescopic section 4022, the pressure of the spray pump, and the temperature of the incineration section 304) are synchronized to the cloud management platform in real time, supporting remote monitoring and fault early warning.

[0064] For example, when the filtration resistance of purification component 6 exceeds the threshold, the system automatically generates a maintenance work order and pushes it to the maintenance personnel's terminal, improving the overall intelligence level of the device.

[0065] The IoT module enables real-time data interaction and remote management of devices via 5G or industrial Ethernet. Its core functions include:

[0066] Data Acquisition and Synchronization: Real-time acquisition of operating parameters of each component and synchronization to the cloud management platform.

[0067] Intelligent prediction and control: The concentration sensor integrates AI algorithms, which can not only detect the composition of exhaust gas in real time, but also predict the trend of exhaust gas concentration fluctuations through historical data (such as predicting a surge in exhaust gas volume within half an hour) and trigger the pre-adjustment of corresponding components in advance to avoid processing delays.

[0068] Remote monitoring and maintenance: Supports remote monitoring of equipment operation status in the cloud. When an anomaly occurs, maintenance work orders are automatically generated and pushed to the maintenance personnel's terminal, realizing fault early warning and intelligent maintenance, reducing labor costs and improving equipment reliability.

[0069] The present invention also includes a waste gas treatment method, which utilizes a modified asphalt waste gas treatment device and includes the following steps:

[0070] S1. Waste gas generated during the production of modified asphalt is introduced into the connecting cavity 4023 of the gas storage pipe 402 through the air supply pipe 401 of the air supply component 4 for storage. The volume of the connecting cavity 4023 is adjusted by the telescopic part 4022 driving the movable plug 4024. When the amount of waste gas is small, the telescopic part 4022 is extended to compress the connecting cavity 4023, thereby increasing the initial speed of the waste gas through the transmission pipe 5 and avoiding impurity residue. When the amount of waste gas is large, the telescopic part 4022 is shortened to expand the connecting cavity 4023, thereby increasing the communication area with the transmission pipe 5 and improving the waste gas treatment efficiency.

[0071] S2. The exhaust gas enters the intake chamber 207 from the air inlet 204 of the cooling component 2 through the transmission pipe 5. Cooling liquid, such as water or coolant, is released through the spray holes of the filter plate 205 to cool the exhaust gas. After cooling, the liquid flows into the return water section 10 through the water outlet 202. The cooled exhaust gas passes through the fixed plate 206 and enters the purification component 6 from the exhaust pipe 203. The purification component 6 filters and removes solid impurities from the exhaust gas.

[0072] S3. The purified exhaust gas enters the detection component 9 through the pipeline. The detection component 9 performs two tests: detects the content of solid impurities in the exhaust gas and judges the purification efficiency of the purification component 6. If the impurity content exceeds the standard, it prompts the maintenance of the purification component 6. It also detects the concentration of organic waste gas such as benzo[a]pyrene and VOCs in the exhaust gas, providing data basis for the treatment mode of the removal component 3.

[0073] S4. Based on the concentration detection results of detection component 9, control the processing mode of removal component 3:

[0074] Low concentration mode: organic waste gas concentration ≤1000mg / m³ 3 The incineration section 304 is not open, the sealing plate 307 is closed, and the through hole of the enclosure plate 309 is open.

[0075] The waste gas enters the treatment chamber 308 through the gas transmission pipe 302. After the organic waste gas is adsorbed by the activated carbon of the adsorption plate 305, it is discharged through the through hole of the enclosure plate 309 and the return gas pipe 303.

[0076] High-concentration mode: organic waste gas concentration > 1000 mg / m³ 3 Open the incineration section 304, close the through hole of the enclosure plate 309, and open the sealing plate 307;

[0077] After initial adsorption by the adsorption plate 305, the exhaust gas passes through the baffle 306 via the path constrained by the enclosure plate 309 and enters the incineration section 304 for high-temperature incineration. After incineration, the exhaust gas is discharged through the return gas pipe 303.

[0078] S5. The concentration sensor in the treatment chamber 308 monitors the composition of the exhaust gas in real time: if it meets the standard, the exhaust gas is discharged through the return pipe 303, the transfer component 8 and the power unit 7.

[0079] If the standard is not met, in low concentration mode, it is determined that the adsorption efficiency of adsorption plate 305 has decreased and needs to be cleaned or replaced; in high concentration mode, the opening area of ​​closed plate 307 is reduced to prolong the residence time of exhaust gas in combustion section 304, and the exhaust gas that does not meet the standard is returned to purification component 6 through power unit 7 for secondary circulation treatment.
