Description

Technical Field

[0001] This invention relates to the field of air pollution control technology, and in particular to a combustion exhaust gas treatment device for air pollution control. Background Technology

[0002] Air pollution control refers to the actions and work undertaken to reduce, control, or remove pollutants in the atmosphere through various means and measures, thereby improving air quality and protecting the environment and human health. In existing technologies, treatment devices typically incorporate filters to remove pollutants from the atmosphere.

[0003] Chinese patent document CN222969475U discloses a pollutant treatment device for air pollution control, including a treatment box. An exhaust fan is fixedly mounted on the upper end of the treatment box, and an exhaust pipe and an exhaust pipe are fixedly mounted on the exhaust fan. One end of the exhaust pipe is fixedly connected to the treatment box. An air inlet pipe is fixedly mounted on one side of the treatment box. A support plate is fixedly mounted inside the treatment box, and two limiting rods are fixedly mounted on the lower end of the support plate. Each limiting rod is movably connected to a striking frame, and multiple striking blocks are fixedly mounted on the lower end of the striking frame. A limiting plate is fixedly connected to the lower end of each limiting rod through the striking frame, and a spring is movably sleeved on the outer side of each limiting rod. A motor is fixedly mounted on one side of the treatment box, and the motor drive end extends into the treatment box and is fixedly connected to a convex column that is rotatably connected to the treatment box. This allows the motor to strike the filter screen, causing it to vibrate and clean. It also allows for quick disassembly of the filter screen for cleaning or replacement, and simultaneously scrapes and cleans the discharge hopper while discharging dust and other pollutant particles.

[0004] The existing technology has the following problems: In existing technologies, filters are commonly used to filter and absorb pollutants in the air. This makes the filters relatively easy to become clogged, requiring regular maintenance. Although some treatment devices use vibration to remove dust from the filters and extend the maintenance interval, this method is difficult to completely remove the dust. Vibration of the filters may damage them. If centrifugal force is used to remove dust, it is difficult to remove some fine dust. Summary of the Invention

[0005] The main objective of this invention is to provide a combustion exhaust gas treatment device for air pollution control, which can effectively solve the problems of high maintenance costs caused by directly using a filter screen for ash removal and the difficulty in removing fine dust by using centrifugal force dust removal.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention provides a combustion exhaust gas treatment device for air pollution control.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: like Figures 1-10 As shown, a combustion exhaust gas treatment device for air pollution control includes a floor 1, a hollow column 2 on the upper side of the floor 1, several annularly distributed air inlets 6 on the outer side of the hollow column 2, an air extraction mechanism 3 on the inner side of the hollow column 2, a dust collection mechanism 4 on the upper side of the hollow column 2, a conical block 5 on the upper side of the dust collection mechanism 4, an annular collection hood 7 on the lower side of the dust collection mechanism 4, the annular collection hood 7 being located on the outer side of the hollow column 2, and a detachable and fixed sealing plate 8 on the lower side of the annular collection hood 7.

[0023] It should be noted that the overall shape of the dust collection mechanism 4 and the hollow column 2 is tree-shaped. It uses dark green solar panels and adds wood grain to the outer surface of the hollow column 2, so that the treatment device can be disguised as a tree. While minimizing the impact on the aesthetics of the surrounding environment, it improves the efficiency of existing exhaust gas treatment devices. The device is equipped with components such as a remote control module, which are integrated into the cone block 5, so that the device can be controlled through the remote control device and the cone block 5.

[0024] Example 2: Preferably, the air extraction mechanism 3 includes a motor 31 disposed inside the hollow column 2. The output end of the motor 31 is fixedly connected to a transmission rod 32. Several annularly distributed first air intake blades 34 are fixedly connected to the upper part of the outer bottom of the transmission rod 32, and the first air intake blades 34 are close to the upper side of the hollow column 2. Several annularly distributed air intake pipes 33 are fixedly connected to the inner side wall of the hollow column 2, and the lower end of the air intake pipes 33 communicates with the air intake hole 6. Several vertically distributed mounting rings 35 are fixedly connected to the outer side of the transmission rod 32, and second air intake blades 36 are fixedly connected to the outer side of each mounting ring 35.

[0025] Preferably, the intake pipe 33 has a spiral structure, and the inner diameter of the intake pipe 33 gradually decreases from bottom to top.

[0026] Preferably, a lifting plate 37 is fixedly connected to the lower side of the motor 31, and several electric telescopic rods 38 are fixedly connected to the inner side of the side wall of the hollow column 2. A cavity for installing the air inlet pipe 33, the electric telescopic rods 38 and the transmission rod 32 is opened on the inner side of the side wall of the hollow column 2. The lower side of the electric telescopic rod 38 is fixedly connected to the upper side of the lifting plate 37 near the edge, and is used to drive the lifting plate 37 to move up and down. The lower side of the cone block 5 overlaps the top of the dust collection mechanism 4, and the lower middle part of the cone block 5 is rotatably connected to the upper end of the transmission rod 32.

[0027] It should be noted that the motor 31 drives the transmission rod 32 to rotate, which causes the transmission rod 32 to drive the first air intake blade 34 and the second air intake blade 36 to revolve, thereby driving the airflow from the air intake hole 6 and the air intake pipe 33 into the inner side of the structure composed of the dust collection mechanism 4 to achieve the purpose of air intake. The structure of the intake pipe 33 allows the incoming gas to automatically rotate in a spiral, avoiding direct blowing onto the first intake blade 34 and the second intake blade 36, which would otherwise subject the first intake blade 34 and the second intake blade 36 to a large lateral pressure. At the same time, the change in the inner diameter of the intake pipe 33 causes the incoming gas flow rate to gradually increase, thereby increasing the centrifugal force. The electric telescopic rod 38 is used to drive the lifting plate 37 to move up and down, thereby increasing the height of the motor 31, transmission rod 32 and conical block 5, which facilitates remote control of the equipment.

[0028] Example 3: Preferably, the dust collection mechanism 4 includes several vertically distributed structural plates 41 fixedly connected end to end. The bottom of the lowest structural plate 41 is fixedly connected to the upper side of the hollow column 2 near the outer edge, and the outer diameter of the structural plates 41 gradually decreases from bottom to top. The structural plate 41 is composed of a first conical ring plate and a second conical ring plate. The first conical ring plate is located above the second conical ring plate, and the lower side of the first conical ring plate near the outer edge is fixedly connected to the upper side of the second conical ring plate near the outer edge. The taper of the first conical ring plate is smaller than that of the second conical ring plate. The top of the uppermost structural plate 41 is closed with a flat plate. The upper end of the transmission rod 32 passes through the middle of the flat plate and connects with the conical block 5. The lower side of the conical block 5 overlaps the upper side of the flat plate. The conical block 5 and the flat plate are fixed by electromagnetic adsorption. The upper side of the annular collection cover 7 is fixedly connected to the lower side of the lowermost structural plate 41 near the outer edge. The bottom wall of the annular collection cover 7 is provided with several leakage holes. The sealing plate 8 is used to seal these leakage holes.

[0029] Preferably, except for the three uppermost structural plates 41, the upper side of the first conical ring plate on the other structural plates 41 is rotatably connected to several annularly distributed rotating components 42 near the outer edge. The rotating components 42 include mounting plates 421. The lower side of the mounting plates 421 is rotatably connected to the upper side of the first conical ring plate on the structural plate 41 near the outer edge. The rotation axis of the mounting plates 421 is not parallel to the central axis of the transmission rod 32. The mounting plates 421 on the same horizontal plane form a complete conical ring. The upper side of the mounting plates 421 is close to the lower side of the second conical ring plate on the structural plate 41 near the outer edge. The upper side of the second conical ring plate on several structural plates 41 is provided with dust collection holes 45, and the uppermost dust collection hole 45 extends downward to the lower side of the first conical ring plate on the adjacent structural plate 41. Solar panels can be detachably installed on the outer side of several mounting plates 421.

[0030] Preferably, except for the three uppermost structural plates 41, the upper side of the first conical ring plate of the other structural plates 41 is fixedly connected with several ring-shaped baffles 43 near the outer edge. The baffles 43 are arc-shaped and located on the side of the mounting plates 421 that are close to each other. Several mounting plates 421 are fixedly connected with blocks 425 on the side of the transmission rod 32. The blocks 425 are located between the baffles 43, and the baffles 43 and blocks 425 located on the same horizontal plane form a complete ring.

[0031] It should be noted that the structure composed of structural plates 41 is tower-shaped, which also increases the airflow speed. Dust in the airflow is affected by centrifugal force and falls on the position between the first and second conical ring plates on the structural plate 41. After passing through the dust collection hole 45, it falls on the upper side of the first conical ring plate on the structural plate 41 and is blocked by the baffle 43 and the block 425, as well as the sealing of the mounting plate 421. The dust is blocked between adjacent structural plates 41 and will not be rolled upward due to the airflow. The solar panels on mounting plate 421 can be dark green, which can minimize the problem of reduced photoelectric conversion efficiency due to color, and also make the device blend into the surrounding environment better. After the mounting plate 421 rotates, the block 425 disengages from the position between the baffles 43, making it convenient to collect dust during maintenance; The annular collection hood 7 is used to collect the dust falling from the dust hole 45 on the bottommost structural plate 41. At the same time, a light panel can be installed on it to further improve the aesthetics of the device at night. Rubber strips are provided on the sides of the mounting plates 421 that are close to each other to prevent air from passing through.

[0032] Example 4: Preferably, a pull rope 422 is fixedly connected to the upper part of the middle of the side of the mounting plate 421 near the transmission rod 32. The end of the pull rope 422 away from the mounting plate 421 passes through the first conical ring plate on the structural plate 41 and enters the inner side of the structure formed by the structural plate 41. The end of the pull rope 422 away from the mounting plate 421 is fixedly connected to a slide block 424. A slide rod 423 is fixedly connected between the lower side of the first conical ring plate on the structural plate 41 near the inner edge and the upper side of the second conical ring plate near the inner edge. The side of the slide block 424 away from the transmission rod 32 is provided with a sliding hole that is slidably connected to the outer wall of the slide rod 423. The structural plate 41 is provided with a guide wheel for changing the moving direction of the pull rope 422. A push block 411 is fixedly connected to the end of each of the second air intake blades 36 away from the transmission rod 32. A slot for inserting the push block 411 is opened on the side of the slide block 424 near the transmission rod 32. The slide rod 423 and the slide block 424 are fixed by electromagnetic adsorption.

[0033] It should be noted that before the transmission rod 32 moves upward, the push block 411 is inserted into the slot on the slide block 424, the electromagnetic attraction between the slide block 424 and the slide rod 423 is disconnected, the transmission rod 32 moves upward, driving the slide block 424 to move upward. A torsion spring for driving is provided between the mounting plate 421 and the structural plate 41, which makes the rotation of the mounting plate 421 on the structural plate 41 more stable. After maintenance operation, the transmission rod 32 moves downward to drive the slide block 424 to reset. Similarly, the mounting plate 421 and the stop bar 43 are connected by electromagnetic adsorption to stabilize the position of the mounting plate 421. The electromagnetic adsorption on the slide block 424 and the slide rod 423 prevents the slide block 424 from moving on the slide rod 423. A flexible telescopic sleeve is fitted onto the slide rod 423, located on the upper and lower sides of the slide block 424. It moves with the slide block 424 to prevent dust from falling on the slide rod 423 and affecting the friction between the slide rod 423 and the slide block 424. The adjacent sliding rods 423 are staggered to avoid affecting the installation of the components.

[0034] Example 5: Preferably, the upper side of the first conical ring plate on the three uppermost structural plates 41 is provided with several annularly distributed air outlet holes 44. The lower side of the first conical ring plate on the three uppermost structural plates 41 is fixedly connected with a detachable filter screen cover 46. The lower side of the first conical ring plate on the three uppermost structural plates 41 and the upper side of the second conical ring plate are fixedly connected with dust guide plates 413. Each layer of dust guide plates 413 is located below the filter screen cover 46. The dust drop hole 45 is located on the side of the dust guide plate 413 near the transmission rod 32. The upper side of the first conical ring plate of the three uppermost structural plates 41, except for the topmost structural plate 41, is fixedly connected with a perforated ring plate 412. The upper end of the perforated ring plate 412 is fixedly connected to the lower side of the second conical ring plate on the upper structural plate 41 near the outer edge.

[0035] Preferably, a rotating frame 47 is rotatably connected to the top inner side of the uppermost structural plate 41. The rotating frame 47 is cylindrical. Several annularly distributed scraping frames 48 are fixedly connected to the outer side of the rotating frame 47. The scraping frames 48 are triangular in shape. Their upper side is used to scrape the lower side of the filter screen 46, and their lower side is used to scrape the upper side of the dust guide plate 413. Several annularly distributed card seats 49 are fixedly connected to the inner side of the rotating frame 47. A card block 410 that engages with the card seat 49 is fixedly connected to the outer side of the transmission rod 32 near the upper side.

[0036] It should be noted that the filter screen 46 is used to filter fine dust in the air, and the porous ring plate 412 is used to seal the gaps between the structural plates 41 to avoid reducing the aesthetics. After the transmission rod 32 moves upward, the locking block 410 is locked into the locking seat 49. Then, the transmission rod 32 rotates and drives the locking seat 49 to rotate, so that the scraping frame 48 scrapes the ash guide plate 413 and the filter screen 46 at the same time. The ash guide plate 413 is used to guide the ash falling on the filter screen 46 to the ash falling hole 45. If only the scraping frame 48 needs to be controlled to perform the scraping operation, the push block 411 will not get stuck in the slot on the slide block 424 before the transmission rod 32 moves up. The rotating frame 47 is fixed to the structural plate 41 by electromagnetic adsorption, so that the rotating frame 47 will not rotate on its own when the locking block 410 is not locked into the locking seat 49.

[0037] The working principle of this invention is as follows: First, the structure composed of structural plates 41 is tower-shaped, which also increases the airflow speed. Dust in the airflow is affected by centrifugal force and falls between the first and second conical ring plates on the structural plate 41. After passing through the dust collection holes 45, the dust falls on the upper side of the first conical ring plate on the structural plate 41 and is blocked by the baffle 43 and the block 425, as well as the sealing of the mounting plate 421. The dust is blocked between adjacent structural plates 41 and will not be rolled upward due to the airflow. The filter screen 46 is used to filter fine dust in the air. The porous ring plate 412 Used to seal the gaps between structural plates 41 to avoid reducing aesthetics. Through the special structure of structural plates 41, centrifugal dust removal is performed without affecting dust collection. Simultaneously, the air after centrifugal dust removal is filtered at the top, avoiding the problems of difficult removal of fine dust or high maintenance costs associated with single dust removal methods. Then, before the transmission rod 32 moves upward, the push block 411 engages with the slot on the slide block 424, disengaging the electromagnetic attraction between the slide block 424 and the slide rod 423. The transmission rod 32 moves upward, causing the slide block 424 to move upward, and the mounting plate... A torsion spring is provided between mounting plate 421 and structural plate 41 for driving, making the rotation of mounting plate 421 on structural plate 41 more stable. After maintenance, the transmission rod 32 moves down to reset the slide 424. The up and down movement of the transmission rod 32 drives the pull rope 422 to move, causing mounting plate 421 to rotate on structural plate 41, thereby achieving the purpose of convenient dust removal without affecting the overall aesthetics. This avoids the problem of the overall structure being abrupt and unsightly due to the dust collection box being directly set at the bottom. At the same time, solar panels can be installed on mounting plate 421. The body is powered by electricity. Finally, the dust collection mechanism 4, together with the hollow column 2, forms a tree shape. It uses dark green solar panels and adds wood grain to the outer surface of the hollow column 2, so that the treatment device can be disguised as a tree. While minimizing the impact on the aesthetics of the surrounding environment, it improves the efficiency of the existing exhaust gas treatment device. Through the structural design of the structural plate 41, the shape of the floor 1, hollow column 2, dust collection mechanism 4, and cone block 5 forms a tree shape, which is convenient to integrate into the surrounding environment and avoids the impact of traditional structural designs on the aesthetics of the equipment installation environment.
