Description

Technical Field

[0001] This invention relates to the field of gas pollution treatment, and in particular to a self-excited dust collector that is easy to maintain. Background Technology

[0002] In mining activities, both during the ore extraction process and the post-mining crushing and processing, a large amount of dust will be generated. In order to prevent the dust from drifting into the air and polluting the environment, special dust removal equipment is needed to treat the gas mixed with the dust.

[0003] Related technology can be found in Chinese Patent No. CN113019024B, which discloses a multi-station wet self-excited dust collector, belonging to the field of separation technology. The multi-station wet self-excited dust collector includes a separation chamber and a flow-guiding structure that introduces water separated by the separation components into a premixing chamber. An air outlet is provided on the top plate of the separation chamber. Separation components are installed on the top wall of the inner cavity of the separation chamber. A partition is located between the water storage chamber and the separation components within the separation chamber. When the water storage chamber contains water, a gap is formed between the bottom edge of the partition and the liquid surface. An air inlet communicating with the premixing chamber is provided on the front side wall of the separation chamber. A connecting cavity connects the gap to the top area of ​​the inner cavity of the separation chamber. An air inlet pipe communicating with the premixing chamber is installed on the rear side wall of the separation chamber. The multi-station wet self-excited dust collector can reduce the distance between the separation plate and the partition, thereby improving structural compactness.

[0004] Regarding the aforementioned technologies, when the airflow enters the separation chamber and contacts the liquid surface inside the chamber at a preset flow angle, the airflow impacts the liquid surface, causing it to slosh and generate water hammer, thus producing water droplets or mist mixed with the airflow, thereby removing dust from the airflow. However, during this process, if the liquid agitation is too large, the liquid level at the air gap will fluctuate. If the liquid level is too high, it can obstruct the normal passage of airflow; if the liquid level is too low, too much airflow can escape, affecting the dust removal effect. Summary of the Invention

[0005] To improve dust removal efficiency, this application provides a self-excited dust collector that is easy to maintain and control.

[0006] This application provides a self-excited dust collector that is easy to maintain and adopts the following technical solution: A self-excited dust collector with easy maintenance includes a dust collection box for holding dust collection liquid. The dust collection box has an air inlet and an exhaust outlet. A fan is installed at the exhaust outlet of the dust collection box. The air inlet is located at the upper end of the dust collection box and is horizontally positioned. The dust collection box has a guide channel for guiding airflow, with one end of the guide channel directly opposite the air inlet. The airflow is horizontal when flowing from the air inlet to the guide channel. A liquid storage box is installed inside the dust collection box, located between the guide channel and the air inlet. The airflow passes over the liquid storage box, and the liquid storage box also contains... The system contains dust removal liquid, and a water-striking component is installed inside the liquid storage box. During airflow, the water-striking component is activated, causing the dust removal liquid in the storage box to vibrate and form a water mist. The other end of the flow guide channel extends to the lower end of the dust removal box and faces the surface of the dust removal liquid to guide the airflow to impact the dust removal liquid. After the airflow comes into contact with the dust removal liquid, it is discharged from the exhaust port. Several flow-damping plates are installed inside the dust removal box. All flow-damping plates are immersed in the dust removal liquid and are arranged along the direction of airflow. Energy-absorbing holes are opened along the arrangement direction of the flow-damping plates.

[0007] By adopting the above technical solution, under the action of the fan, the airflow mixed with airborne dust enters the dust collection box through the air inlet and flows towards the exhaust port under the action of the guide channel. During the flow of the airflow from the air inlet to the guide channel, the water hammer component is activated and knocks against the dust removal liquid in the liquid storage box, causing the dust removal liquid in the liquid storage box to agitate and generate water splashes or mist, which then mix with the airflow and perform a first dust removal. The airflow does not flow towards the surface of the dust removal liquid in the liquid storage box, which helps to reduce the water hammer phenomenon. After the airflow enters the guide channel, it impacts the dust collection liquid inside the dust collection box under the guidance of the guide channel, thereby causing the dust collection liquid to fluctuate and produce water mist, thus performing secondary dust removal. The airflow that has completed secondary dust removal is discharged from the exhaust port under the action of the fan. During the secondary dust removal process, the dust collection liquid tends to fluctuate along the direction of airflow. At this time, all the flow damping plates work together to block the flow of the dust collection liquid and absorb the impact force of the dust collection liquid through the energy absorption holes, thereby reducing the impact of the dust collection liquid on the dust removal effect when the dust collection liquid is violently disturbed, and reducing the damage to the dust collection box caused by water hammer phenomenon of the dust collection liquid, thus reducing maintenance needs and difficulty.

[0008] Optionally, the water-striking assembly includes a support plate, several water-striking blocks, a transmission component, and a wind power unit. The support plate is horizontally fixed inside the liquid storage box. The several water-striking blocks are arranged along the length of the support plate and are all hinged to the support plate vertically. The wind power unit is used to capture the wind energy of the airflow and convert it into mechanical energy. The transmission component is located between the wind power unit and the water-striking blocks. When the wind power unit is working, the mechanical energy generated is transmitted to the water-striking blocks by the transmission component, causing the water-striking blocks to swing back and forth vertically and continuously impact the dust removal liquid.

[0009] By adopting the above technical solution, the support plate supports the corresponding water-slapping blocks. When the airflow enters the dust collector box along the air inlet, the wind power unit captures the wind energy generated during the airflow and converts the wind energy into mechanical energy. Under the transmission action of the transmission component, the mechanical energy converted by the wind power unit drives the water-slapping blocks to swing vertically, causing the water-slapping blocks to hit and impact the dust removal liquid in the liquid storage box, thereby causing the dust removal liquid to splash and remove dust from the airflow.

[0010] Optionally, the water-striking block is divided into a connecting part and an impact part along its length. The connecting part is used to connect with the support plate and drive the impact part to swing vertically under the action of the transmission component. The impact part has a through groove along its vertical length, and two extrusion plates are fixedly connected to the impact part along the length of the through groove. The two extrusion plates are located on both sides of the through groove along its width, and the end faces of the two extrusion plates that are close to each other are inclined from bottom to top in the direction of approaching each other.

[0011] By adopting the above technical solution, the support plate supports the connecting part. When the connecting part flips and swings, it drives the impact part to swing synchronously. When the impact part hits the water surface, the dust removal liquid is squeezed by two extrusion plates. Under pressure, the dust removal liquid passes through the channel and splashes upward to form a water wall, which helps to improve the contact area and mixing effect between the airflow and the dust removal liquid.

[0012] Optionally, the impact part is fixed with water-slapping plates on both sides along the width direction. The water-slapping plates are inclined from bottom to top along the direction from the connecting part to the impact part. The water-slapping plates have two facing and parallel maximum end faces, and the water-slapping plates have several squeezing holes that penetrate the two maximum end faces. When the impact part drives the water-slapping plates to impact the dust removal liquid, the maximum end face of the water-slapping plates is facing the dust removal liquid.

[0013] By adopting the above technical solution, when the impact part contacts the surface of the dust removal liquid, the dust removal liquid is struck by the water-slapping plate, causing the dust removal liquid to pass through the water-slapping hole and splash upward, thereby further improving the splashing effect of the dust removal liquid and enhancing the mixing effect of the dust removal liquid and the airflow.

[0014] Optionally, the dust collector includes a first air guide plate, a second air guide plate, and a third air guide plate. The first air guide plate and the second air guide plate are corresponding to each other and are fixedly connected to the dust collector. The second air guide plate is located above the first air guide plate and faces the airflow passing through the air inlet. The gap between the first air guide plate and the second air guide plate forms a flow channel. The first air guide plate is located on the side of the second air guide plate closer to the exhaust port, and a ventilation gap is left below the first air guide plate for the airflow to pass through. The third air guide plate is located on the side of the first air guide plate away from the second air guide plate, and the gap between the third air guide plate and the first air guide plate forms a return channel. The return channel is used to guide the airflow passing through the ventilation gap to collide with the dust removal liquid again.

[0015] By adopting the above technical solution, the first and second air guide plates guide the airflow through the liquid storage box to collide with the dust removal liquid at the bottom of the dust removal box, thereby achieving secondary mixing and dust removal. The third air guide plate is used to prevent the airflow from escaping directly after secondary dust removal, and works with the second air guide plate to guide the airflow to turn around again after colliding with the dust removal liquid and repeatedly contact the dust removal liquid, thereby achieving a third dust removal, which helps to improve the dust removal effect of the airflow.

[0016] Optionally, a number of adhesive plates are arranged on the side wall of the first air guide plate facing the second air guide plate along the gas flow direction. The end face of the adhesive plate facing the second air guide plate is provided with an adhesive layer. A disassembly port is opened on one side of the dust collector. All adhesive plates pass through the disassembly port and are fixedly connected to the same mounting plate. The mounting plate is detachably connected to the dust collector by bolts, and the disassembly port is sealed in the installed state.

[0017] By adopting the above technical solution, when the airflow flows along the air guide plate, the adhesive plate adheres to the solid particles in the airflow through the adhesive layer, thereby improving the dust removal effect. Furthermore, all adhesive plates can be removed from the disassembly port by disassembling the mounting plate, which facilitates cleaning or replacement of the adhesive layer.

[0018] Optionally, all the flow-retarding plates are slidably connected to the dust collection box in the vertical direction, and the dust collection box is equipped with a lifting component for moving all the flow-retarding plates. Scrapers are placed on both ends of the flow-retarding plates in the horizontal direction, and the scrapers are attached to the flow-retarding plates and fixedly connected to the dust collection box.

[0019] By adopting the above technical solution, when cleaning the solid impurities deposited at the bottom of the dust collector, all the flow dampers are raised by the lifting component, which facilitates the rinsing of the bottom of the dust collector. During the vertical movement of the flow dampers, the solid particles attached to the flow dampers are cleaned by the scraper. The dust collector does not need to be disassembled during maintenance, which helps to improve the convenience of dust collector maintenance.

[0020] Optionally, a water-blocking plate is also fixedly installed inside the dust collection box. The water-blocking plate is located below the exhaust port and is horizontally arranged. The water-blocking plate and the inner wall of the dust collection box form an exhaust channel. When the fan is working, it drives the airflow to flow along the exhaust channel toward the exhaust port. Several condensation plates are arranged vertically inside the exhaust channel. The condensation plates are fixedly connected to the dust collection box. When the airflow enters the exhaust channel, it passes between adjacent condensation plates. The condensation plates are used to prevent the dust collection liquid from being discharged with the airflow.

[0021] By adopting the above technical solution, the water blocking plate is used to prevent the airflow that has completed dust removal from escaping directly and to guide the airflow to flow into the exhaust channel. When the gas passes through the water condensation plate, the water vapor in the airflow is condensed by the water condensation plate, which reduces the probability of water vapor being discharged with the airflow and helps to reduce the loss of dust removal liquid.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Under the action of the fan, the airflow mixed with airborne dust enters the dust collector through the inlet and flows towards the exhaust outlet under the action of the guide channel. As the airflow flows from the inlet to the guide channel, the water hammer component is activated and knocks against the dust-collecting liquid in the liquid storage box, causing the liquid in the storage box to agitate and generate water droplets or mist, which then mix with the airflow and perform a first dust removal. The airflow does not flow towards the surface of the dust-collecting liquid in the storage box, thus helping to reduce the water hammer phenomenon. After the airflow enters the guide channel, it impacts the dust removal liquid inside the dust collector under the guidance of the guide channel, thereby causing the dust removal liquid to fluctuate and produce water mist, thus performing secondary dust removal. The airflow that has completed secondary dust removal is discharged from the exhaust port under the action of the fan. During the secondary dust removal process, the dust removal liquid tends to fluctuate along the direction of airflow. At this time, all the flow damping plates work together to block the flow of the dust removal liquid and absorb the impact force of the dust removal liquid through the energy absorption holes, thereby reducing the impact of the dust removal liquid on the dust removal effect when the dust removal liquid is violently disturbed, and reducing the damage to the dust collector caused by water hammer phenomenon of the dust removal liquid, thus reducing maintenance needs and difficulty. 2. Air guide plate one and air guide plate two guide the airflow through the liquid storage box to collide with the dust removal liquid at the bottom of the dust removal box, thereby achieving secondary mixing and dust removal. Air guide plate three is used to prevent the airflow from escaping directly after secondary dust removal, and works with air guide plate two to guide the airflow to turn around again after colliding with the dust removal liquid and repeatedly contact the dust removal liquid, thereby achieving tertiary dust removal, which helps to improve the dust removal effect of the airflow.

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] This application discloses a self-excited dust collector that is easy to maintain. Example

[0031] Reference Figure 1 and Figure 2 A self-excited dust collector with easy maintenance includes a dust collection box 1, which is hollow and contains a dust collection liquid at the bottom. Specifically, water is used as the dust collection liquid, which can effectively reduce costs. When the airflow to be dusted contains other pollutants, other liquids that can neutralize the pollutants can also be used. The dust collection box 1 has an air inlet 11 and an exhaust port 12 that communicate with the outside. A fan 13 is installed at the exhaust port 12. When the fan 13 is working, it discharges the gas in the dust collection box 1 and allows outside gas to enter the dust collection box 1 through the air inlet 11 under air pressure.

[0032] Reference Figure 1 and Figure 2 An air intake pipe can be installed at the air inlet 11, with the end of the air intake pipe away from the dust collector 1 extending into the working space where dust removal is required. During operation, under negative pressure, the airflow requiring dust removal flows from the air intake pipe to the air inlet 11 and enters the dust collector 1 along the air inlet 11. The air inlet 11 is located at the upper end of the dust collector 1 and is horizontally positioned, allowing the airflow entering the dust collector 1 to flow horizontally.

[0033] Reference Figure 1 and Figure 2The dust collector 1 is equipped with a first air guide plate 14, a second air guide plate 15, and a third air guide plate 16. The first air guide plate 14 is located above the second air guide plate 15, and both the first air guide plate 14 and the second air guide plate 15 are fixedly connected to the inner wall of the dust collector 1, so that the first air guide plate 14, the second air guide plate 15 and the inner wall of the dust collector 1 cooperate to form a flow channel. One end of the flow channel is set horizontally and is directly opposite the air inlet 11, and the other end is bent vertically and tilted from top to bottom towards the dust removal liquid at the bottom of the dust collector 1.

[0034] Reference Figure 3 and Figure 4 In dust collection box 1 (reference) Figure 2 The dust collector 1 also includes a liquid storage box 2, located between the air inlet 11 and the guide channel. Under the action of the fan 13, the airflow enters the dust collector 1, passes over the liquid storage box 2, and flows through the guide channel. The liquid storage box 2 is horizontally positioned and contains the same dust removal liquid as described above. A water-striking assembly is installed inside the liquid storage box 2. The water-striking assembly includes a support plate 31, multiple water-striking blocks 32, a transmission component, and a wind unit 34. The support plate 31 is horizontally positioned along the direction from the air inlet 11 towards the guide channel, and is fixedly connected to the liquid storage box 2.

[0035] Reference Figure 4 and Figure 5 Multiple water-striking blocks 32 are arranged along the length of the support plate 31 and are perpendicular to the support plate 31. Each water-striking block 32 has a connecting portion 321 and an impact portion 322 at both ends along its length. The connecting portion 321 is hinged vertically to the support plate 31, and the impact portion 322 is located at the end of the connecting portion 321 away from the support plate 31. Under the support of the support plate 31, when the impact portion 322 is in an upward-curving state, it completely detaches from the dust removal liquid in the storage box 2; when the impact portion 322 is in a downward-curving state, it is completely immersed in the dust removal liquid. The impact portion 322 has a through groove 323 along the swing direction, and two extrusion plates 324 are fixedly connected along the length of the through groove 323. Both extrusion plates 324 are located within the through groove 323 and are fixedly connected to the inner wall of the through groove 323. The end faces of the two extrusion plates 324 approach each other in an upward direction.

[0036] Reference Figure 4 and Figure 5The wind unit 34 includes an air impeller 341 and a transmission rod 342. The air impeller 341 is located at the air inlet 11 and is rotatably connected to the dust collector 1 around its own axis. When the airflow passes through the air inlet 11, it drives the air impeller 341 to rotate. The transmission rod 342 is connected to the side of the air impeller 341 facing the airflow channel. When the air impeller 341 rotates, it drives the transmission rod 342 to rotate. The transmission components include a rotating rod 331, a cam 332, a connecting rod 333, and a lifting block 334. The lifting block 334 corresponds to the water-striking block 32 and is slidably connected to the support plate 31 vertically. The lifting block 334 has a groove along the width direction of the support plate 31 that corresponds one-to-one with the water-striking block 32. A round rod parallel to the support plate 31 is vertically fixed to the connecting part 321. The round rod is located in the groove and moves along the groove. Under the support of the support plate 31, when the lifting block 334 moves vertically, it drives the connecting part 321 to swing vertically through the round rod.

[0037] Reference Figure 4 and Figure 5 The rotating rod 331 is arranged parallel to the support plate 31. A vertical plate for supporting the rotating rod 331 is fixed at the upper end of the support plate 31. The rotating rod 331 passes through the vertical plate and is rotatably connected to the vertical plate around its own axis. A gear set is provided between the transmission rod 342 and the rotating rod 331. When the transmission rod 342 rotates, it drives the rotating rod 331 to rotate through the gear set. The gear set helps to improve the speed ratio between the transmission rod 342 and the rotating rod 331, thereby increasing the speed of the rotating rod 331.

[0038] Reference Figure 4 and Figure 5 The cam 332 is mounted on the end of the rotating rod 331 away from the transmission rod 342, and rotates synchronously with the rotating rod 331 when the rotating rod 331 rotates. One end of the connecting rod 333 is hinged to the cam 332, and the other end is hinged to the lifting block 334. When the cam 332 rotates, it drives the lifting block 334 to move vertically through the connecting rod 333, thereby causing the lifting block 334 to drive all the water-striking blocks 32 on the same support plate 31 to swing vertically. When the water-striking blocks 32 swing, they continuously strike the dust removal liquid in the storage tank through the impact part 322. When the impact part 322 contacts the surface of the dust removal liquid, the two extrusion plates 324 cooperate to squeeze the dust removal liquid, causing the dust removal liquid to pass through the through groove 323 and splash upward to form a water wall perpendicular to the airflow direction, thereby increasing the contact area between the airflow and the dust removal liquid, so that the airflow mixes with the splashed dust removal liquid when it flows, thereby performing the first dust removal.

[0039] Reference Figure 4 and Figure 5A water-splashing plate 325 is fixedly attached to both sides of the impact part 322 along its width direction. The water-splashing plate 325 is inclined from bottom to top along the direction from the connecting part 321 towards the impact part 322, and the two vertical end faces of the water-splashing plate 325 are the largest end faces of the water-splashing plate 325. When the impact part 322 drives the water-splashing plate 325 to contact the dust removal liquid, the largest end face of the water-splashing plate 325 faces the dust removal liquid directly. The impact plate strikes the dust removal liquid through the water-splashing plate, thereby increasing the splashing effect of the dust removal liquid. Furthermore, the water-splashing plate 325 has several squeezing holes 326 connecting the two largest end faces. When the water-splashing plate strikes the dust removal liquid, the dust removal liquid squeezed by the water-splashing plate is squeezed out from the squeezing holes 326, thereby further improving the water-splashing effect of the water-splashing plate 325 and enhancing the dust removal effect.

[0040] Reference Figure 2 and Figure 3 When the airflow enters the liquid storage box 2, it does not directly impact the dust removal liquid inside, reducing the probability of violent fluctuations in the liquid. Initial dust removal is only achieved through water splashes and mist generated during the movement of the impacted part 322, thus ensuring effective dust removal. A drain port is provided at the lower end of the liquid storage box 2, and a drain pipe connected to the drain port is fixed to the liquid storage box 2. The drain pipe passes through the dust removal chamber 1 and extends to the outside to drain the dust removal liquid from the liquid storage box. The dust removal chamber 1 is also fixedly connected to an inlet pipe, one end of which connects to the outside, and the other end extends above the liquid storage box 2 to add dust removal liquid to the liquid storage box 2. It should be noted that both the inlet pipe and the drain pipe are equipped with on / off valves.

[0041] Reference Figure 1 and Figure 2 The side of the first air guide plate 14 closest to the second air guide plate 15 is directly opposite the exhaust port 12. After the airflow enters the guide channel, it impacts the first air guide plate 14 and flows towards the dust removal liquid at the bottom of the dust collector 1 under the guidance of the first air guide plate 14. Multiple adhesive plates 171 are arranged along the airflow direction on the side of the first air guide plate 14 closest to the second air guide plate 15. All adhesive plates 171 are embedded in the first air guide plate 14 and are slidably connected to the guide plate laterally. A disassembly port communicating with the outside is opened on one side of the dust collector 1. All adhesive plates 171 pass through the disassembly port and are connected to the same mounting plate 172. The mounting plate 172 is provided with multiple bolts, which pass through the mounting plate 172 and are threadedly connected to the dust collector 1, thereby pressing the mounting plate 172 tightly onto the dust collector 1 and sealing the disassembly port.

[0042] Reference Figure 1 and Figure 2The end face of the adhesive plate 171 facing the air guide plate 15 is coated with an adhesive layer. When the airflow flows along the air guide plate 14, the adhesive plate 171 adheres to and separates solid particles in the airflow through the adhesive layer. After removing the bolts on the mounting plate 172, all adhesive plates 171 can be removed from the dust collection box 1 through the disassembly port by disassembling the mounting plate 172, which facilitates the cleaning, maintenance or replacement of the adhesive layer.

[0043] Reference Figure 1 and Figure 2 A ventilation gap is formed between the lower end of the second air guide plate 15 and the dust removal liquid at the bottom of the dust collector 1, allowing airflow to pass through. The airflow impacts the dust removal liquid along the first air guide plate 14 and mixes with splashing water or water mist to complete the second dust removal. The airflow that has completed the second mixing and dust removal flows through the ventilation gap to the exhaust port 12 under the action of the fan 13. A third air guide plate 16 is also installed inside the dust collector 1. The third air guide plate 16 is located below the second air guide plate 15, and the gap between the third air guide plate 16 and the second air guide plate 15 forms a return channel. The airflow enters the return channel after passing through the ventilation gap and flows along the return channel. The end of the return channel near the exhaust port 12 is inclined from top to bottom to guide the airflow to contact the dust removal liquid at the bottom of the dust collector 1 again, thereby performing a third mixing and dust removal.

[0044] Reference Figure 1 and Figure 2 Multiple flow-damping plates 4 are arranged at the bottom of the dust collector 1, along the airflow direction, and are all slidably connected to the dust collector 1 vertically. The dust collector 1 is equipped with a lifting component 5 for driving all the flow-damping plates 4 to move vertically. The lifting component 5 includes a motor and a lead screw. The motor is installed inside the dust collector 1 and above the dust-collecting liquid. All the flow-damping plates 4 have the same crossbar fixed to their upper ends, and each flow-damping plate 4 is fixedly connected to a slider. The lead screw is vertically positioned and rotatably connected to the dust collector 1 around its own axis. The lead screw passes through the slider and is threadedly connected to it. The motor output shaft is coaxially connected to the lead screw. When the motor is working, it drives the lead screw to rotate, causing the lead screw to move all the flow-damping plates 4 vertically via the slider. Furthermore, a sealed outer shell is fitted around the motor to reduce the probability of the dust-collecting liquid corroding the motor. Similarly, two flexible telescopic tubes are fitted around the lead screw, located on both sides of the slider vertically, protecting the lead screw during slider movement.

[0045] Reference Figure 1 and Figure 2When the airflow impacts the dust removal liquid at the bottom of the dust removal box 1, the dust removal liquid will fluctuate along the direction of airflow. At this time, all the flow damping plates 4 work together to block the flow trend of the dust removal liquid. The flow damping plates 4 have multiple energy absorption holes 41 along the direction of the dust removal liquid swaying. The energy absorption holes 41 are arranged in a radially conical shape. When the dust removal liquid flows, it passes through the energy absorption holes 41. The flow damping plates 4 absorb the impact force of the dust removal liquid through the energy absorption holes 41, thereby reducing the probability of the dust removal liquid swaying violently.

[0046] Reference Figure 1 and Figure 2 The bottom of the dust collector 1 is connected to a drain pipe 2, which is located at the lowest end of the inner wall of the dust collector 1. When cleaning the dust removal liquid inside the dust collector 1, the dust removal liquid and the precipitated solid impurities are discharged together through the drain pipe 2. The dust collector 1 is also connected to a liquid inlet pipe 2. When the dust removal liquid in the dust collector 1 is less than a preset value, the dust removal liquid is replenished into the dust collector 1 through the liquid inlet pipe 2. A liquid detection unit for monitoring the dust removal liquid level is installed inside the dust collector 1. The aforementioned switch valves are also installed on the liquid inlet pipe 2 and the drain pipe 2.

[0047] Reference Figure 1 and Figure 2 Scrapers 18 are provided on both sides of the flow-retardant plate 4 along the transverse direction. The scrapers 18 are fixedly connected to the dust collection box 1 and are in contact with the maximum end face of the flow-retardant plate 4. In the initial state, all the flow-retardant plates 4 are located at the bottom of the dust collection box 1 and are immersed in the dust removal liquid. When cleaning and maintaining the dust collection box 1, the flow-retardant plate 4 is moved upward by the lifting component 5, so that when the dust removal liquid flows to the drain pipe 2, it carries the impurities deposited on the bottom surface of the dust collection box 1 out together. When the flow-retardant plate 4 moves upward, the scrapers 18 clean the maximum end face of the flow-retardant plate 4, thereby scraping off the impurities attached to the flow-retardant plate 4. When cleaning the bottom of the dust collection box 1 and the flow-retardant plate 4, it is not necessary to disassemble the dust collection box 1, which improves the convenience of cleaning and maintenance.

[0048] Reference Figure 1 and Figure 2 A water-blocking plate 19 is fixed inside the dust collector 1. The water-blocking plate 19 is located below the exhaust port 12 and forms an exhaust channel with the inner wall of the dust collector 1. The airflow that has undergone three dust removal processes flows into the exhaust channel under the action of the fan 13. Multiple condensation plates 191 are arranged in the exhaust channel. When the airflow flows into the exhaust channel, it passes between adjacent condensation plates 191. The condensation plates 191 are used to condense water vapor in the airflow. This is existing technology and will not be described in detail here. Before the airflow exits the dust collector 1, the condensation plates 191 prevent the dust removal liquid from being discharged from the exhaust port 12 with the airflow, which helps to reduce the loss of the dust removal liquid.

[0049] The implementation principle of a self-excited dust collector with easy maintenance according to an embodiment of this application is as follows: The fan 13 draws in the airflow requiring dust removal from the outside. Guided by the flow channel, the airflow enters the dust collection box 1 and flows horizontally. At this time, the fan blade unit captures the wind energy generated during the airflow and converts it into mechanical energy. Under the action of the transmission components, the water-striking block 32 continuously strikes the dust-removing liquid in the liquid storage box 2, causing the dust-removing liquid to splash and form water mist. The airflow mixes with the water mist, and some of the dust particles in the airflow are captured by the water mist and fall into the liquid storage box 2, thus completing the initial dust removal. When the airflow flows along the flow channel, the adhesive plate 171 adheres to the solid particles in the airflow through the adhesive layer. Then, the airflow collides with the dust-removing liquid at the bottom of the dust collection box 1 along the airflow channel, thus performing a second dust removal. After the second dust removal, the airflow is guided vertically in a rotating flow by the cooperation of the air guide plate 3 16 and the air guide plate 2 15, causing the airflow to collide with the dust-removing liquid again, thus completing the third dust removal process, thereby ensuring the dust removal effect. When the airflow impacts the dust removal liquid, the flow damper 4 absorbs the kinetic energy applied to the liquid by the airflow, thereby reducing the probability of violent shaking of the liquid and ensuring the dust removal effect. When cleaning the dust collection box 1, the flow damper 4 is raised, and the scraper 18 is used to clean the maximum end face of the flow damper 4. At the same time, the raised flow damper 4 facilitates the rinsing of the bottom of the dust collection box 1. The dust collection box 1 does not need to be completely disassembled during cleaning and maintenance, which improves the convenience of maintenance.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
