Description

Technical Field

[0001] This invention belongs to the field of gas pollution control technology, specifically an air pollution control device. Background Technology

[0002] In existing technologies, for specific scenarios such as small businesses, processing workshops and laboratories, the treatment of exhaust gas is based on the example of sulfur dioxide in exhaust gas. If the concentration is too high, it will inevitably cause harm to the human body that inhales the exhaust gas. Therefore, in specific scenarios, it is necessary to use exhaust gas treatment equipment in a timely manner, which can also be understood as air pollution control equipment to treat exhaust gas. Chinese patent CN118904061B discloses a purification device for air pollution control, including a purification chamber. One side of the purification chamber is connected to an air inlet assembly, and the other side is connected to an exhaust pipe and a sewage discharge assembly. Inside the purification chamber are a filter assembly, a corresponding brushing assembly, and a control assembly. The brushing assembly is located below the filter assembly. A motor is mounted on one side of the purification chamber, and the output shaft of the motor is fixedly connected to a rotating column. The end of the rotating column is connected to a rotating cylinder that rotatably engages within the purification chamber. This technical solution uses an electric push rod to extend and retract, causing a connecting plate, an extension plate, and an arc-shaped baffle to shift. This allows for adjustment of the arc-shaped baffle to block the aerosol nozzles or flushing nozzles. Combined with the motor driving the rotating cylinder, this enables the aerosol nozzles to evenly spray the desulfurization solution, and the flushing nozzles to rinse the filter assembly and its mesh.

[0003] In the aforementioned prior art, sulfur dioxide in the exhaust gas reacts with the desulfurizing agent to generate solid impurities. However, in a device, or what can be understood as a box, the generated solid impurities will fall onto the bottom screen plate under their own gravity. After a period of time, they will block the screen holes, causing obstruction of gas flow. Therefore, when using this type of equipment to treat exhaust gas, it is necessary to stop the machine periodically to clean the screen plate. By changing the nozzle angle, the screen plate can be directly sprayed to achieve the purpose of rapid cleaning. However, in the aforementioned prior art, nozzle switching and drum control both require active intervention, which is quite cumbersome.

[0004] Therefore, the present invention provides an air pollution control device. Summary of the Invention

[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] like Figures 1 to 4 , Figure 9 As shown in the embodiment of the present invention, an air pollution control device includes a treatment chamber 1, a filter plate 7, a slag removal module 8, and a drive module 4. The bottom side wall of the treatment chamber 1 is connected to an air inlet pipe 2. A detachable top cover 14 is provided on the top of the treatment chamber 1. An adjustable nozzle 6 is provided on the top of the treatment chamber 1 for spraying desulfurizing agent. The filter plate 7 is fixed inside the treatment chamber 1 for filtering impurities. Slag collection holes 71 are provided at the four corners of the filter plate 7 for collecting impurities. The slag removal module 8 rotates... Connected to the filter plate 7, it is used to clean impurities and push them towards the slag collection hole 71; the drive module 4 is vertically rotatably connected inside the processing box 1, and drives the slag cleaning module 8 to move through the air intake pipe 2; a series shaft 62 is rotatably connected inside the processing box 1, and a deflection plate 61 is fixedly connected to the series shaft 62; the adjusting nozzle 6 is fixedly connected to the deflection plate 61; an adjusting spindle is provided inside the adjusting nozzle 6, and a thin rope 63 is fixedly connected to the end of the adjusting spindle; the thin rope 63 is used to adjust the adjusting nozzle 6.

[0023] The end of the adjusting spindle is connected to the ring 412 by a thin rope 63. When the angle of the adjusting nozzle 6 is adjusted, the relative position of the adjusting spindle within the adjusting nozzle 6 changes because the position of the ring 412 does not change. This allows for the switching between water jets and droplets. It can be understood that during the stage of treating exhaust gas, the adjusting nozzle 6 outputs droplets, which can increase the contact area with the exhaust gas and thus improve the treatment efficiency. However, if there is no exhaust gas to be treated, it is more convenient to use a water jet to rinse the filter plate 7. Therefore, in one embodiment, the switching between water jets and droplets is achieved by changing the angle of the adjusting nozzle 6, making the adjusting nozzle 6 in this embodiment of the invention more adaptable and multifunctional.

[0024] The slag removal module 8 includes a scraper 81, a ratchet 84, and an extension plate 82. The tail of the scraper 81 is engaged with the outer wall of the ratchet 84, and the extension plate 82 is slidably connected to the hollow groove on the side wall of the scraper 81. A sliding rod 83 is fixedly connected to the bottom surface of the hollow groove, and the tail of the extension plate 82 is slidably connected to the sliding rod 83. A third spring 85 is fixedly connected between the extension plate 82 and the bottom surface of the hollow groove, and the third spring 85 is sleeved on the sliding rod 83. The head of the extension plate 82 is slidably engaged with the inner wall of the processing box 1.

[0025] In one embodiment of the present invention, exhaust gas is drawn into the treatment chamber 1 through the inlet pipe 2, specifically introduced to the bottom of the treatment chamber 1. Taking advantage of the gas's light weight and upward flow, a desulfurizing agent is evenly sprayed using an adjustable nozzle 6. The upward-flowing exhaust gas comes into full contact with the downward-falling droplets, thus completing the desulfurization reaction. The solid impurities generated after the reaction fall onto the surface of the filter plate 7. The filter plate 7 traps these impurities, allowing the desulfurizing agent that has not fully reacted with sulfur to be collected at the bottom of the treatment chamber 1 for recycling, reducing the amount of desulfurizing agent used and lowering the cost of exhaust gas treatment. As described above, when all the solid impurities fall onto the filter plate 7 and are trapped by it, after a period of time... After a period of time, the filter holes will inevitably become clogged, preventing gas from passing through individual filter holes or reducing the volume of gas passing through the filter plate 7 per unit time, thus affecting the efficiency of waste gas treatment. Furthermore, the waste gas treatment time is prolonged, resulting in some waste gas escaping. Therefore, in one embodiment, when there are solid impurities on the filter plate 7 and the air inlet pipe 2 is still in the air intake state, the air intake enables the drive module 4 to drive the cleaning module 8 to move. When the cleaning module 8 rotates under the action of the drive module 4, it relies on the scraper 81 to rotate around the axis of the drive module 4, that is, when the scraper 81 rotates around the center of the filter plate 7, it can scrape off and collect the impurities remaining on the filter plate 7. With the movement of the scraper 81, the impurities are removed and collected. The solid impurities will all be collected on one side of the scraper 81. As the scraper 81 moves, when the scraper 81 moves to any corner of the filter plate 7, since the distance from the slag collection hole 71 at any corner of the filter plate 7 to the center of the filter plate 7 is greater than the distance from the side of the filter plate 7 to the center of the filter plate 7, some of the solid impurities previously collected on one side of the scraper 81 will fall into the slag collection hole 71 and thus detach from the surface of the filter plate 7. However, in order to achieve sufficient removal of impurities from the surface of the filter plate 7, in one embodiment, a slidingly fitted extension plate 82 is provided on the side of the scraper 81. When the head of the scraper 81 moves to any corner of the filter plate 7, due to the increased distance, the third spring 85 can drive the extension plate 82 to slide outward centrifugally, so that the solid impurities near the center of the filter plate 7 can be removed. Solid impurities gradually approach the edge of the filter plate 7 and, after multiple cycles, are pushed into the slag collection hole 71 by the extension plate 82, thus completing the full treatment of solid impurities on the filter plate 7. Based on the above, the present invention uses the air intake pipe 2 to drive the drive module 4, and then uses the drive module 4 to drive the slag cleaning module 8 to work. During the desulfurization process of waste gas reaction, the slag cleaning module 8 continuously cleans the filter plate 7, which can effectively extend the working time of the filter plate 7, eliminating the need for frequent shutdowns for maintenance. Moreover, the continuous cleaning of the filter plate 7 during the desulfurization process of waste gas reaction ensures that the waste gas can be treated efficiently in a single waste gas treatment process, without causing the waste gas treatment efficiency to decline linearly, which is conducive to the rapid removal of sulfur elements in the waste gas.

[0026] like Figure 1 , Figures 7 to 8As shown, the processing box 1 includes a first box section 11, a second box section 12, and a third box section 13 stacked vertically. The top cover 14 is detachably connected to the top surface of the first box section 11. A first connecting strip 111 is fixedly connected to the included corner of each surface inside the first box section 11, and a second connecting strip 124 is correspondingly fixedly connected to the inside of the second box section 12. The first box section 11 is snapped onto the top of the second box section 12 via the first connecting strip 111. A partition 123 is fixedly connected to the included corner of each surface inside the second box section 12, and the partition 123 extends to the outside of the second bottom surface. The second box section 12 is snapped onto the top of the third box section 13 via the partition 123.

[0027] In one embodiment of the present invention, the processing box 1 is configured as a combination of a first box section 11, a second box section 12, and a third box section 13. This facilitates the installation of the drive module 4 and the slag removal module 8 during use. Specifically, a first connecting strip 111 is welded to the included angle between two adjacent surfaces of the first box section 11, with its bottom protruding from the bottom surface of the first box section 11. This strip is used to insert into the top of the second box section 12. A second connecting strip 124, welded at the same position within the second box section 12, connects end-to-end with the first connecting strip 111. Inside the second box section 12, specifically at the bottom of the included angle between two adjacent surfaces, an inclined partition 123 is fixedly connected. The bottom of the partition 123 bends parallel to the side wall of the second box section 12. Figure 3 As shown, the bottom of the partition 123 extends outward from the bottom surface of the second box section 12. Using the partition 123, the second box section 12 can be inserted into the surface of the third box section 13. Thus, the first box section 11, the second box section 12, and the third box section 13 are completely assembled. As for the above-mentioned convenient installation of the drive module 4 and the slag cleaning module 8, in this embodiment, the bottom of the drive module 4 is rotatably connected to the bottom surface of the second box section 12, while the slag cleaning module 8 is installed inside the second box section 12, specifically in contact with the top surface of the partition 123. Therefore, by sequentially installing the first box section 11, the second box section 12, and the third box section 13, the drive module 4 and the slag cleaning module 8 can be conveniently installed.

[0028] like Figure 8 As shown, a detachable plate 121 is snapped onto the outside of the second box section 12 corresponding to the partition 123; the partition 123, the second box section 12, and the detachable plate 121 form a discharge chamber; a connecting hole 122 is opened on the bottom surface of the discharge chamber, and the connecting hole 122 connects to the third box section 13; the filter plate 7 is fixed to the top of the partition 123 by screws, and the slag collection hole 71 corresponds to the discharge chamber.

[0029] As described above, a partition 123 is provided inside the second box section 12, and the partition 123 is arranged at an oblique angle with the adjacent two surfaces inside the second box section 12. Therefore, an independent space is separated between the partition 123 and the adjacent two surfaces inside the second box section 12, which is separated from the internal space of the second box section 12. Based on this, a removable plate 121 is provided on the outer wall of the second box section 12 corresponding to the position of the partition 123. In one embodiment, the partition 123, the second box section 12, and the removable plate 121 can be used to separate a discharge chamber, and the discharge chamber is aligned with the slag collection hole 71. When the scraper 81 or the extension plate pushes the impurities into the slag collection hole 71, they can all be collected. The waste is collected in the feeding chamber. Furthermore, a connecting hole 122 is opened at the bottom of the feeding chamber, and the connecting hole 122 connects to the third box section 13. Then, the impurities falling into the feeding chamber can be further guided into the third box section 13 under the action of gravity, realizing the separation of solid impurities and desulfurization liquid. This ensures that the desulfurization liquid entering the internal space of the second box section 12 can be recycled. It is worth noting that in the second box section 12, and above the filter plate 7, a slanted guide plate can also be set corresponding to the slag collection hole 71. The guide plate is used to prevent the falling desulfurizing agent from falling into the feeding chamber through the slag collection hole 71, which would cause impurities and desulfurizing agent to coexist in the third box section 13, resulting in the waste of desulfurizing agent.

[0030] like Figures 3 to 4 As shown, the drive module 4 includes a first drive section 41, a second drive section 42, and a fan blade 43; the fan blade 43 is fixedly connected to the bottom of the second drive section 42 and corresponds to the output port of the air inlet pipe 2; the second drive section 42 is rotatably connected to the center of the bottom surface of the second housing section 12, and the first drive section 41 and the second drive section 42 are splined together; the top of the second drive section 42 passes through the filter plate 7, and a pawl 421 is fixedly connected to the top side wall; the ratchet gear 84 is sleeved on the top of the second drive section 42, and the pawl 421 engages with the ratchet gear 84.

[0031] In one embodiment, the drive module 4 can rotate based on the intake of air through the intake pipe 2. Specifically, when the intake pipe 2 is inlet, the gas is drawn in through the intake pipe 2 head and output to the interior of the second box section 12 through the output port at the tail of the intake pipe 2. The tail of the intake pipe 2 is perpendicular to the side wall of the second box section 12 and is directly opposite the fan blade 43. Therefore, when the intake pipe 2 is inlet, the output airflow can drive the fan blade 43 to rotate. After the fan blade 43 rotates, it can engage with the ratchet gear 84 through the pawl 421 at the top of the second drive section 42 and drive the ratchet gear 84 to rotate synchronously. At this time, the scraper 81 fixed to the side of the ratchet gear 84 can rotate synchronously with the ratchet gear 84, thereby cleaning the impurities on the filter plate 7.

[0032] like Figures 3 to 5As shown, the series shaft 62 is rotatably connected to both sides inside the first box section 11, the thin rope 63 passes through the output port of the adjusting nozzle 6 and is fixedly connected to the ring 412 on the side wall of the first drive section 41; the ring 412 is rotatably connected to the first drive section 41.

[0033] In one embodiment, the desulfurizing agent is output from an adjusting nozzle 6, the tail of which is connected to a desulfurizing agent pipeline (not shown in the figure). The dense droplets output from the adjusting nozzle 6 can react with the sulfur element in the exhaust gas during their descent, thereby completing desulfurization. In one embodiment of the present invention, the adjusting nozzle 6 is fixed on a deflection plate 61, and the deflection plate 61 is fixedly connected to a series shaft 62. It can be understood that multiple deflection plates 61 can be connected in series on one series shaft 62, and multiple adjusting nozzles 6 can be carried on multiple deflection plates 61. Since the series shaft 62 is rotatably connected to the inner wall of the first box section 11, it means that the adjusting nozzle 6 can achieve angle adjustment. Changing the angle of the adjusting nozzle 6 can change the time when the droplets fall onto the filter plate 7, and can form a dense droplet network, so that the exhaust gas passing through the droplet network can be fully desulfurized. In addition, in this embodiment, the adjusting nozzle 6 has a... An adjusting spindle is provided. By utilizing the relative position of the adjusting spindle within the adjusting nozzle 6, the switching between water jets and droplets can be achieved. The specific principle is existing technology and will not be elaborated here. Based on this, the end of the adjusting spindle is connected to the ring 412 via a thin rope 63. When the angle of the adjusting nozzle 6 is adjusted, since the position of the ring 412 does not change, the relative position of the adjusting spindle within the adjusting nozzle 6 is changed, thereby achieving the switching between water jets and droplets. It can be understood that during the stage of treating exhaust gas, adjusting the nozzle 6 to output droplets can increase the contact area with the exhaust gas, thereby improving the treatment efficiency. However, if there is no exhaust gas to be treated, and it is desired to rinse the filter plate 7, using a water jet is more convenient. Therefore, in one embodiment, by changing the angle of the adjusting nozzle 6, the switching between water jets and droplets is achieved, making the adjusting nozzle 6 in this embodiment of the invention more adaptable and multifunctional.

[0034] like Figures 3 to 5 As shown, it also includes an adjustment module 5, which is located inside the first housing section 11. It is used to actively change the angle of the adjustment nozzle 6 and adjust the adjustment nozzle 6 in conjunction with the thin rope 63. When air enters the air intake pipe 2, it drives the fan blade 43 to rotate, which in turn drives the first drive section 41 and the second drive section 42 to rotate. Then, the adjustment module 5 drives the deflection plate 61 to deflect, which indirectly drives the adjustment nozzle 6 to deflect. When the adjustment nozzle 6 rotates, the thin rope 63 pulls the adjustment spindle to move inside the adjustment nozzle 6, thus completing the adjustment of the adjustment nozzle 6.

[0035] Following the above, in one embodiment of the present invention, an adjustment module 5 is also included, which can actively change the angle of the adjustment nozzle 6. Based on the adjustment module 5, the switching between water jet and droplet output of the adjustment nozzle 6 is realized. Specifically, when exhaust gas is output from the outlet of the air inlet pipe 2 into the second box section 12, the fan blade 43 drives the first drive section 41 and the second drive section 42 to rotate. When the second drive section 42 rotates, it can drive the adjustment module 5 to move, and then drive the deflection plate 61 to deflect through the adjustment module. Since the adjustment nozzle 6 is set on the deflection plate 61, when the deflection plate 61 deflects, it means that the angle of the adjustment nozzle 6 is also adjusted. At this time, since the length of the thin rope 63 is limited and the position of the ring 412 is relatively stationary, the relative position of the adjustment spindle in the adjustment nozzle 6 changes, which allows the adjustment nozzle 6 to switch the output mode, that is, output water jet or droplet.

[0036] like Figures 3 to 5 As shown, the adjustment module 5 includes a mounting bracket 51, a rack 52, a long shaft 54, an adjustment arm 53, and a second spring 56; a fixing plate 112 is fixedly connected inside the first box section 11, and the mounting bracket 51 is fixedly connected to the fixing plate 112; the rack 52 is slidably connected to one side of the mounting bracket 51, the long shaft 54 ​​is fixedly connected to the other side of the mounting bracket 51, and the second spring 56 is sleeved on the long shaft 54; the top of the adjustment arm 53 is hinged to the deflection plate 61, and the bottom of the adjustment arm 53 is horizontally driven by the rack 52; two adjustment modules 5 are provided and arranged in a circular array about the first drive section 41; the rack 52 in one adjustment module 5 is slidably connected to the long shaft 54 ​​in the other adjustment module 5, and the rack 52 in one adjustment module 5 drives the adjustment arm 53 in the other adjustment module 5 to slide.

[0037] Furthermore, when the second drive section 42 rotates, the gear 413 can drive the rack 52 to move, causing the rack 52 to move towards the other mounting bracket 51. Initially, the tail of the rack 52 in one adjustment module 5 is close to the tail of the mounting bracket 51. When the gear 413 rotates, the rack 52 in one adjustment module 5 will move towards the mounting bracket 51 of the other adjustment module 5, and squeeze the second spring 56 during the displacement. Since the number of teeth is limited, in one embodiment, it is assumed that when the gear 413 disengages from the teeth, the bottom of the adjustment arm 53 can be pushed to the tail of the mounting bracket 51 by the rack 52. At this time, since the top of the adjustment arm 53 is hinged to the side wall of the deflection arm, the multi-link structure composed of the deflection plate 61, the adjustment arm 53 and the rack 52 can drive the deflection plate 61 and the series shaft 62 to rotate, thereby causing the adjustment nozzle 6 to deflect at a certain angle. Figure 4 or Figure 5As shown, in the initial state, the adjusting nozzle 6 is tilted downwards. When the bottom of the deflecting arm is driven by the rack 52 in another adjusting module 5 and approaches the tail of the mounting bracket 51 in another adjusting module 5, the deflecting plate 61 will be lifted upwards. At this time, the adjusting nozzle 6 is almost horizontal, thus forming a droplet net, which facilitates full contact between the exhaust gas and the droplet net to achieve desulfurization. It can be understood that because the number of teeth on the rack 52 is limited, after the rack 52 reaches its limit position, the gear 413 and the side of the rack 52 are in a sliding engagement relationship, no longer in a meshing relationship. At this time, the angle of the adjusting nozzle 6 remains relatively unchanged, thus achieving an almost stable state. At the same time, due to the traction of the thin rope 63... This allows the output of the adjusting nozzle 6 to be switched. Assuming that the adjusting nozzle 6 is initially in a downward direction, the output is a water column. The adjusting nozzle 6 outputs droplets. However, when the second drive section 42 stops rotating, that is, when the air inlet pipe 2 stops taking in air, the gear 413 stops driving the rack 52. At this time, the rack 52 actively resets under the action of the second spring 56 and drives the adjusting arm 53 to reset. At this time, the deflection plate 61 resets, and the adjusting nozzle 6 also resets. The adjustment mode returns to the water column state. At this time, the air inlet pipe 2 stops taking in air. The idle time and the water column output mode of the adjusting nozzle 6 can be used to rinse the filter plate 7 and the inside of the treatment box 1.

[0038] like Figures 3 to 6 As shown, the adjustment module 5 further includes a slider 55, which is slidably connected to the long shaft 54; the adjustment arm 53 is hinged to the side wall of the slider 55; a short shaft 521 parallel to the moving direction of the rack 52 is fixedly connected to the end of the rack 52 in one of the adjustment modules 5, and the short shaft 521 passes through the slider 55. A first spring 551 is sleeved on the short shaft 521, and the two ends of the first spring 551 are respectively fixed to the end of the rack 52 in one of the adjustment modules 5 and the end of the slider 55 in the other adjustment module 5.

[0039] like Figures 5 to 6 As shown, a gear 413 is fixedly connected to the middle of the first drive section 41, and the gear 413 meshes with the racks 52 in both adjustment modules 5; a guide part 411 is fixedly connected to the bottom of the first drive section 41.

[0040] During the aforementioned process, when rack 52 reaches its limit position, gear 413 and rack 52 change from a meshing state to a sliding engagement state. Due to the presence of the second spring 56, rack 52 always tends to reset. However, gear 413, driven by the second drive section 42, always rotates and contacts rack 52. Therefore, rack 52 actually reciprocates within a certain range. At this time, deflection plate 61 connected via adjusting arm 53 will also swing within a certain angle range, which is not conducive to the stability of adjusting nozzle 6. Based on this, in one embodiment, the bottom of adjusting arm 53 is hinged to slider 55, and slider 55 slides on long axis 54 like rack 52. When rack 52 in one adjusting module 5 is displaced to another adjusting module 5... When the rack 52 is in motion, the short shaft 521 can be used to connect the rack 52 and the slider 55. At the same time, the first spring 551 is added to achieve a soft connection between the rack 52 and the slider 55. When the rack 52 is displaced, the slider 55 is driven to slide based on the first spring 551. The slider 55 drives the bottom radial displacement of the adjusting arm 53. When the rack 52 reaches the limit position, the rack 52 and the slider 55 on the same side are also softly connected based on the short shaft 521 and the first spring 551. Even if the rack 52 still moves back and forth within a certain range, it will not directly drive the slider 55 to drive the adjusting arm 53 to swing. Therefore, the force of the rack 52 directly acting on the adjusting arm 53 is reduced to a certain extent, so that the deflection plate 61 carrying the adjusting nozzle 6 is in a relatively stable state.

[0041] In addition, the guide part 411 at the bottom of the first drive section 41 can prevent the generated solid impurities from falling into the ratchet 84 position, which is the center position of the filter plate 7. The solid impurities in this area are difficult to be pushed into the slag collection hole 71 by the scraper 81 and the extension plate. At the same time, the solid impurities falling here will affect the cooperation between the pawl 421 and the ratchet 84. Therefore, the guide part 411 can guide the solid impurities to the outside of the center of the filter plate 7, and then remove them by the scraper 81 and the extension plate.

[0042] like Figures 1 to 2 As shown, the top of the top cover 14 is connected to an air outlet pipe 141, and a dust cover 142 is fixedly connected to the top of the air outlet pipe 141; a water pipe 3 is connected to the side wall of the processing box 1.

[0043] In one embodiment, the purified exhaust gas can be discharged through the exhaust pipe 141. The water pipe 3 installed on the side wall of the treatment box 1 includes an inlet pipe 3 body connected to the tank for storing desulfurizing agent externally, and a circulation pipe body. Furthermore, a branch pipe can be connected to the inlet pipe 3 body for separately connecting pure water to achieve cleaning of the inside of the treatment box 1.

[0044] Working principle: Exhaust gas is drawn into the treatment chamber 1 through the inlet pipe 2, specifically introduced to the bottom of the treatment chamber 1. Taking advantage of the gas's light weight and upward flow, the desulfurizing agent is evenly sprayed using the adjustable nozzle 6. The upward-flowing exhaust gas comes into full contact with the downward-dripping droplets, thus completing the desulfurization reaction. The solid impurities generated after the reaction fall onto the surface of the filter plate 7. The filter plate 7 traps these impurities, allowing the desulfurizing agent that has not fully reacted with sulfur to be collected at the bottom of the treatment chamber 1 for recycling, reducing the amount of desulfurizing agent used and lowering the cost of exhaust gas treatment. As mentioned above, when all the solid impurities fall onto the filter plate 7 and are trapped by it, it will inevitably become clogged after a period of time. Blocked filter holes prevent gas from passing through certain holes, or reduce the volume of gas passing through the filter plate 7 per unit time, thus affecting the efficiency of waste gas treatment. Furthermore, the waste gas treatment time is prolonged, leading to partial escape of waste gas. Therefore, in one embodiment, when solid impurities are present on the filter plate 7 and the air inlet pipe 2 remains in the air intake state, the air intake enables the drive module 4 to drive the cleaning module 8 to move. When the cleaning module 8 rotates under the action of the drive module 4, it relies on the scraper 81 to rotate circumferentially around the axis of the drive module 4, that is, when the scraper 81 rotates circumferentially around the center of the filter plate 7, it can scrape and collect the residual impurities on the filter plate 7. With the movement of the scraper 81, the impurities are thoroughly removed. The solid impurities that previously accumulated on one side of the scraper 81 move with the scraper 81. When the scraper 81 moves to any corner of the filter plate 7, because the distance from the slag collection hole 71 at any corner of the filter plate 7 to the center of the filter plate 7 is greater than the distance from the side of the filter plate 7 to the center of the filter plate 7, some of the solid impurities that were previously accumulated on one side of the scraper 81 will fall into the slag collection hole 71 and thus detach from the surface of the filter plate 7. However, in order to achieve sufficient removal of impurities from the surface of the filter plate 7, in one embodiment, a slidingly fitted extension plate 82 is provided on the side of the scraper 81. When the head of the scraper 81 moves to any corner of the filter plate 7, due to the increased distance, the third spring 85 can drive the extension plate 82 to slide outward centrifugally, so that the solid impurities near the center of the filter plate 7 can be removed. The solid impurities gradually approach the edge of the filter plate 7 and, after multiple cycles, are pushed into the slag collection hole 71 by the extension plate 82, thereby completing the full treatment of solid impurities on the filter plate 7. Based on the above, the present invention uses the air intake pipe 2 to drive the drive module 4, and then uses the drive module 4 to drive the slag cleaning module 8 to work. During the desulfurization process of the waste gas reaction, the slag cleaning module 8 continuously cleans the filter plate 7, which can effectively extend the working time of the filter plate 7, eliminate the need for frequent shutdowns for maintenance, and continuously clean the filter plate 7 during the desulfurization process of the waste gas reaction, so that the waste gas can be treated efficiently in a single waste gas treatment process, without causing the waste gas treatment efficiency to decline linearly, which is conducive to quickly removing sulfur elements from the waste gas. The second chamber section 12 is equipped with a partition 123, and the partition 123 is arranged at an oblique angle with the adjacent two sides of the second chamber section 12. Therefore, the partition 123 and the adjacent two sides of the second chamber section 12 can be separated into an independent space, which is separated from the internal space of the second chamber section 12. On this basis, a removable plate 121 is set on the outer wall of the second chamber section 12 corresponding to the position of the partition 123. In one embodiment, the partition 123, the second chamber section 12 and the removable plate 121 can be used to separate a feeding chamber, and the feeding chamber is aligned with the slag collection hole 71. When the scraper 81 or the extension plate pushes the impurities into the slag collection hole 71, they can be collected in the feeding chamber. Furthermore, a connecting hole 122 is opened at the bottom of the feeding chamber, and the connecting hole 122 connects to the third chamber section 13. Then, the impurities falling into the feeding chamber can be further guided into the third chamber section 13 under the action of gravity, realizing the separation of solid impurities and desulfurization liquid, and ensuring that they enter the second chamber section 12. The desulfurization liquid in the secondary compartment can be recycled. It is worth noting that in the second compartment 12, above the filter plate 7, an inclined guide plate can be set corresponding to the slag collection hole 71. The guide plate is used to prevent the falling desulfurizing agent from falling into the discharge chamber through the slag collection hole 71, which would cause impurities in the third compartment 13 to coexist with the desulfurizing agent, resulting in waste of the desulfurizing agent. When the air inlet pipe 2 is inlet, the gas is drawn in through the head of the air inlet pipe 2 and output to the interior of the second compartment 12 through the outlet of the tail of the air inlet pipe 2. The tail of the air inlet pipe 2 is perpendicular to the side wall of the second compartment 12 and is directly opposite the fan blade 43. Therefore, when the air inlet pipe 2 is inlet, the output airflow can drive the fan blade 43 to rotate. After the fan blade 43 rotates, it can cooperate with the ratchet gear 84 through the pawl 421 at the top of the second drive section 42 and drive the ratchet gear 84 to rotate synchronously. At this time, the scraper 81 fixed to the side of the ratchet gear 84 can rotate synchronously with the ratchet gear 84, thereby cleaning the impurities on the filter plate 7.The dense droplets output by the adjustable nozzle 6 can react with sulfur in the exhaust gas during their descent, thereby completing desulfurization. In one embodiment of the invention, the adjustable nozzle 6 is fixed on a deflector plate 61, and the deflector plate 61 is fixedly connected to a series shaft 62. It can be understood that multiple deflector plates 61 can be connected in series on one series shaft 62, and multiple adjustable nozzles 6 can be supported on multiple deflector plates 61. Since the series shaft 62 is rotatably connected to the inner wall of the first box section 11, this means that the adjustable nozzle 6 can achieve angle adjustment. Changing the angle of the adjustable nozzle 6 can, firstly, change the time it takes for the droplets to fall onto the filter plate 7, and secondly, form a dense droplet network, thereby ensuring that the exhaust gas passing through the droplet network is fully desulfurized. Furthermore, in this embodiment, an adjusting mandrel is provided inside the adjustable nozzle 6. The relative position allows for switching between water jets and droplets. The specific principle is existing technology and will not be elaborated here. Based on this, a thin rope 63 connects the end of the adjusting spindle to the ring 412. When the angle of the adjusting nozzle 6 is adjusted, since the position of the ring 412 does not change, the relative position of the adjusting spindle within the adjusting nozzle 6 changes, thus achieving the switching between water jets and droplets. It can be understood that during the stage of treating exhaust gas, adjusting the nozzle 6 to output droplets increases the contact area with the exhaust gas, thereby improving treatment efficiency. However, if there is no exhaust gas to treat, and the filter plate 7 needs rinsing, using a water jet is more convenient. Therefore, in one embodiment, changing the angle of the adjusting nozzle 6 achieves the switching between water jets and droplets, making the adjusting nozzle 6 in this embodiment of the invention more adaptable and multifunctional.

[0045] When the second drive section 42 rotates, the gear 413 can drive the rack 52 to move, causing the rack 52 to move towards the other mounting bracket 51. Initially, the tail of the rack 52 in one adjustment module 5 is close to the tail of the mounting bracket 51. When the gear 413 rotates, the rack 52 in one adjustment module 5 will move towards the mounting bracket 51 of the other adjustment module 5, and squeeze the second spring 56 during the displacement. Since the number of teeth is limited, in one embodiment, it is assumed that when the gear 413 disengages from the teeth, the bottom of the adjustment arm 53 can be pushed to the tail of the mounting bracket 51 by the rack 52. At this time, since the top of the adjustment arm 53 is hinged to the side wall of the deflection arm, the multi-link structure composed of the deflection plate 61, the adjustment arm 53 and the rack 52 can drive the deflection plate 61 and the series shaft 62 to rotate, thereby causing the adjustment nozzle 6 to deflect at a certain angle. Figure 4 or Figure 5As shown, in the initial state, the adjusting nozzle 6 is tilted downwards. When the bottom of the deflecting arm is driven by the rack 52 in another adjusting module 5 and approaches the tail of the mounting bracket 51 in another adjusting module 5, the deflecting plate 61 will be lifted upwards. At this time, the adjusting nozzle 6 is almost horizontal, thus forming a droplet net, which facilitates full contact between the exhaust gas and the droplet net to achieve desulfurization. It can be understood that because the number of teeth on the rack 52 is limited, after the rack 52 reaches its limit position, the gear 413 and the side of the rack 52 are in a sliding engagement relationship, no longer in a meshing relationship. At this time, the angle of the adjusting nozzle 6 remains relatively unchanged, thus achieving an almost stable state. At the same time, due to the traction of the thin rope 63... This allows the output of the adjusting nozzle 6 to be switched. Assuming that the adjusting nozzle 6 is initially in a downward direction, the output is a water column. The adjusting nozzle 6 outputs droplets. However, when the second drive section 42 stops rotating, that is, when the air inlet pipe 2 stops taking in air, the gear 413 stops driving the rack 52. At this time, the rack 52 actively resets under the action of the second spring 56 and drives the adjusting arm 53 to reset. At this time, the deflection plate 61 resets, and the adjusting nozzle 6 also resets. The adjustment mode returns to the water column state. At this time, the air inlet pipe 2 stops taking in air. The idle time and the water column output mode of the adjusting nozzle 6 can be used to rinse the filter plate 7 and the inside of the treatment box 1.
