[0002] Because petrochemical and chemical sites are filled with exhaust gases and noise levels that exceed human tolerance, it is required to meet environmental protection standards for on-site emissions. Exhaust gas treatment devices are often used to treat exhaust gas emissions and solve the problems of loud noise, strong odor, and high temperature during exhaust gas emissions. However, the commonly used exhaust gas treatment devices generally have the following disadvantages.

[0003] 1. Traditional equipment is fixed and welded, which cannot meet the emission requirements of multiple locations throughout the site;

[0004] 2. Traditional equipment interfaces are relatively simple and cannot meet the needs of various pipe openings on site;

[0005] 3. Traditional equipment circuits are relatively simple and cannot simultaneously meet the requirements of high on-site temperature, large flow rate, high impurity content, and strong odor. Summary of the Invention

[0019] 1. Compared with existing technologies, this deodorizing and noise-reducing vehicle mounts the treatment device on the chassis, allowing it to be towed and moved using a common trailer, meeting the needs of the entire site. By configuring multiple sets of access flanges with sizes ranging from DN20 to DN200, it can meet different pipe opening requirements.

The guide structure ensures that the lifting structure remains stable during movement.

[0020] 2. Compared to existing technologies, this deodorizing and silencing vehicle is equipped with a filter, heat exchanger, buffer tank, silencer, and activated carbon adsorption tank connected in sequence. The inlet pipe for the medium is connected to the filter, heat exchanger, and buffer tank respectively, and then controlled by an electronically controlled valve controlled by a controller. This allows the deodorizing and silencing vehicle to be suitable for working conditions with high temperature, high impurity content, and high flow rate of the medium, as well as working conditions with high temperature and low impurity content, and working conditions with low temperature and low impurity content. It has a wide range of applications. First, the filter removes residual solid particles and other impurities from the discharged medium. Then, the heat exchanger reduces the temperature to a temperature that is tolerable for the human body. Next, the high-efficiency buffer tank reduces the flow rate of the medium to a reasonable range, while excess liquid in the medium settles at the bottom of the equipment for regular drainage. After the flow rate is reduced, the medium passes through an impedance composite silencer to reduce the sound to a level that is tolerable for the human body. Finally, the activated carbon adsorption tank deodorizes the medium before it is discharged into the atmosphere. Attached Figure Description

[0028] 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.

[0029] Example:

[0030] like Figures 1 to 6 As shown, this embodiment of the invention provides a deodorizing and noise-reducing vehicle, including a controller, multiple sets of electrically controlled valves, multiple sets of pipes, and a frame 1. A base plate 2 is provided on the upper surface of the frame 1. A lifting structure for adjusting the height of the base plate 2 is provided between the frame 1 and the base plate 2. The lifting structure includes two sets of first rotating seats 11, slide rails 19, sliding seats 17, channel steel 22, and an X-shaped support frame 20. The two sets of first rotating seats 11 are sequentially and fixedly connected to the upper wall of the frame 1, facing each other. The two sets of slide rails 19 are sequentially and fixedly connected to the upper wall of the frame 1, facing each other, and both are located behind the first rotating seats 11. The two sets of sliding seats 17 are slidably connected to the upper walls of the two sets of slide rails 19. Two sets of connecting rods 18 are fixedly connected between opposite sides of the two sets of sliding seats 17. The X-shaped support frame 20 is formed by four support plates connected by connecting shafts. The four ends of the lower part of the X-shaped support frame 20 are respectively... The X-shaped support frame 20 is rotatably connected to two sets of first rotating seats 11 and sliding seats 17. Rollers 21 are rotatably connected to the four opposite ends of the upper end of the X-shaped support frame 20. Two sets of channel steels 22 are fixedly connected to the inner upper wall of the base plate 2 and are parallel to the two sets of slide rails 19. Sliding grooves 23 are provided between the opposite sides of the two sets of channel steels 22. The four sets of rollers 21 are rotatably connected to the inner walls of the two sets of sliding grooves 23. The four support plates in the X-shaped support frame 20 form a scissor structure due to the connection of the connecting shaft. When the sliding seat 17 is pushed towards the first rotating seat 11, the upper and lower openings of the X-shaped support frame 20 close, thereby increasing the height. When the sliding seat 17 moves away from the first rotating seat 11, the upper and lower openings of the X-shaped support frame 20 open, thereby decreasing the height. By adjusting the height, the connection flange 8 can be adapted to the height of the on-site pipe opening.

[0031] A drive assembly for driving the lifting structure is provided between the frame 1 and the lifting structure. The drive assembly is connected to the lifting structure by two sets of connecting rods 18. The drive assembly includes a second rotating seat 12, a third rotating seat 13, a drive motor 15, a lead screw 14, and a sliding block 16. The second rotating seat 12, the third rotating seat 13, and the drive motor 15 are fixedly connected to the upper wall of the frame 1 in a front-to-back order and are located in the center of the left and right sides of the frame 1. The lead screw 14 is rotatably connected between the second rotating seat 12 and the third rotating seat 13 and passes through the third rotating seat 13. One end of seat 13 is fixedly connected to the end of the extended shaft of drive motor 15 via a coupling. Sliding block 16 is threadedly connected to the outer wall of lead screw 14 and located between the second rotating seat 12 and the third rotating seat 13. The opposite ends of the two sets of connecting rods 18 are fixedly connected to the left and right side walls of sliding block 16 respectively. When drive motor 15 rotates forward and reverses, it drives lead screw 14 to rotate forward and rotate. Lead screw 14 is threadedly connected to sliding block 16, which drives sliding block 16 to move forward and backward along lead screw 14. Then, through the two sets of connecting rods 18, it drives sliding seat 17 to move back and forth, thus completing the driving action of lifting structure.

[0032] A guide structure for guiding the lifting and lowering of the base plate 2 is also provided between the base plate 2 and the frame 1. The guide structure includes four guide pillars 5 and four sets of guide sleeves 4. The four sets of guide sleeves 4 are all fixedly connected to the inner upper wall of the base plate 2 and are respectively close to the four corners. The four guide pillars 5 are all fixedly connected to the upper wall of the frame 1 and are respectively vertically corresponding to the four sets of guide sleeves 4. The ends of the four guide pillars 5 away from the frame 1 are slidably connected to the inner walls of the four sets of guide sleeves 4. Through the four guide pillars 5 and the four sets of guide sleeves 4, the base plate 2 can move smoothly when it is driven to lift and lower by the drive component and the lifting structure.

[0033] A housing 3 is fixedly connected to the upper wall of the base plate 2. From back to front, a filter 25, heat exchanger 26, buffer tank 27, silencer 28, and activated carbon adsorption tank 29 are sequentially arranged on the upper wall of the base plate 2 and inside the housing 3. The filter 25 is connected to the heat exchanger 26, the heat exchanger 26 to the buffer tank 27, the buffer tank 27 to the silencer 28, and the silencer 28 to the activated carbon adsorption tank 29 via pipes. The filter 25 is a basket filter structure, the heat exchanger 26 is a plate heat exchange structure, and the silencer 28 is an impedance composite silencer structure. Multiple sets of inlet flanges 8 are fixedly connected to the left wall of the housing 3, near the rear wall. The ends of the multiple sets of inlet flanges 8 facing the housing 3 penetrate the side wall of the housing 3 and extend into the interior of the housing 3. The ends of the multiple sets of inlet flanges 8 extending into the housing 3 are all fixedly connected to an inlet pipe 24. The inlet pipe 24 is connected to the filter 25 and heat exchanger 26 via multiple sets of pipes. The system is connected to a buffer tank 27. A drain outlet 9 is fixedly connected to the right wall of the housing 3. The end of the drain outlet 9 facing the housing 3 passes through the housing 3 and extends into the interior of the housing 3. The end of the drain outlet 9 extending into the interior of the housing 3 is connected to the bottom of the filter 25, heat exchanger 26, buffer tank 27, silencer 28 and activated carbon adsorption tank 29 through multiple sets of drain pipes 32. A cooling tower 10 is installed on the top of the housing 3. The cooling tower 10 is connected to the heat exchanger 26 through a pipe. The filter 25 is used to filter the residual particulate matter in the discharged medium. The heat exchanger 26 reduces the temperature of the discharged medium through the cooling effect of the cooling tower 10. The buffer tank 27 is used to reduce the flow rate of the medium to a reasonable range and at the same time, the excess liquid in the medium settles at the bottom of the equipment for timed drainage. The silencer 28 can reduce the sound to a level that is bearable for the human body. The activated carbon adsorption tank 29 can deodorize the medium and then discharge the medium into the atmosphere.

[0034] The rear wall of the housing 3 is provided with a first maintenance door 6 for easy maintenance of the filter 25, and the left wall of the housing 3 near the front wall is provided with a second maintenance door 7 for easy maintenance of the activated carbon adsorption tank 29. The inner wall of the second maintenance door 7 is provided with an exhaust window 30 that runs through the inside and outside. By opening the first maintenance door 6 and the second maintenance door 7, the filter 25 and the activated carbon adsorption tank 29 can be easily maintained.

[0035] A backflush structure for backflushing is provided between the buffer tank 27 and the filter 25 and activated carbon adsorption tank 29. Multiple sets of electrically controlled valves are respectively installed on the outer walls of multiple sets of pipes, at the connection between multiple sets of inlet flanges 8 and inlet pipe 24, on the outer wall of the sewage pipe 32, and on the backflush structure. The backflush structure is a backflush pipe 31. A bypass outlet is provided on the outer wall of the buffer tank 27. Backflush ports are provided on the outer walls of the filter 25 and activated carbon adsorption tank 29. The backflush pipe 31 is connected between the bypass outlet and the two sets of backflush ports. Through the backflush structure, the filter 25 and activated carbon adsorption tank 29 do not need to be disassembled or the activated carbon replaced for a certain period of time, which can ensure the filtration and adsorption effect for a long time. The size range of the multiple sets of inlet flanges 8 is DN20-DN200. By setting different specifications of inlet flanges 8, the needs of different pipe sizes on site can be met.

[0036] Working principle: Filter 25 filters residual particulate matter in the discharged medium. Heat exchanger 26 reduces the temperature of the discharged medium through the cooling tower 10. Buffer tank 27 reduces the medium flow rate to a reasonable range and allows excess liquid in the medium to settle at the bottom of the equipment for periodic drainage. Silencer 28 reduces noise to a tolerable level. Activated carbon adsorption tank 29 deodorizes the medium before discharging it into the atmosphere. Filter 25 and activated carbon adsorption tank 29 can be easily maintained by opening the first maintenance door 6 and the second maintenance door 7. Filter 25 and activated carbon adsorption tank 29, through a backflushing structure, do not require filter element disassembly or activated carbon replacement for a certain period, ensuring filtration and adsorption effects over a long period. Multiple sets of inlet flanges 8 are available in sizes ranging from DN20 to DN200. The same specification of the access flange 8 can meet the needs of different pipe opening sizes on site. When the drive motor 15 rotates forward and reverses, it drives the lead screw 14 to rotate forward and reverse. The lead screw 14 is connected to the sliding block 16 by a thread, which drives the sliding block 16 to move forward and backward along the lead screw 14. Then, through the two sets of connecting rods 18, it drives the sliding seat 17 to move back and forth, completing the driving action of the lifting structure. The four support plates in the X-shaped support frame 20 form a scissor structure due to the connection of the connecting shaft. When the sliding seat 17 is pushed towards the first rotating seat 11, the upper and lower openings of the X-shaped support frame 20 are closed, thereby increasing the height. When the sliding seat 17 moves away from the first rotating seat 11, the upper and lower openings of the X-shaped support frame 20 open, thereby decreasing the height. By adjusting the height, the access flange 8 can be adapted to the height of the pipe opening on site.
