[0035] like Figure 1 As shown, the flue gas dust removal equipment provided by this invention includes a first flue gas dust removal device 1 and a second flue gas dust removal device 2. An inlet pipe 3 introduces the flue gas to be dusted into the first flue gas dust removal device 1 through a first branch pipe 31, and introduces the flue gas to be dusted into the second flue gas dust removal device 2 through a second branch pipe 32. One-way valves are installed in the first branch pipe 31 and the second branch pipe 32 respectively. The user allows the flue gas to enter either the first flue gas dust removal device 1 or the second flue gas dust removal device 2 as needed for dust removal. When using the first flue gas dust removal device 1 for dust removal, the second flue gas dust removal device 2 can be cleaned, or vice versa, to enable continuous dust removal without shutting down the system. The first flue gas dust removal device 1 and the second flue gas dust removal device 2 have the same structure; the following description uses the first flue gas dust removal device 1 as an example.
[0036] Also refer to Figures 2 to 5The first flue gas dust removal device 1 includes a lower dust removal assembly 11 and an upper dust removal assembly 12 mounted on the lower dust removal assembly 11. The lower dust removal assembly 11 includes a dust chamber 111, an air inlet assembly 112 mounted on the dust chamber 111, an electrostatic dust removal assembly 113 mounted in the dust chamber 111, and a dust collection chamber 115 mounted on the lower side of the dust chamber 111. Preferably, the dust chamber 111 is generally a hollow square. The air inlet assembly 112 is mounted on one side of the top of the dust chamber 111. The air inlet assembly 112 includes at least one set of first air inlets 121 and second air inlets 122, wherein the first air inlets 121 and the second air inlets 122 are rotatably mounted on the dust chamber 111, and the first air inlet 121 drives the second air inlet 122 to rotate. A first branch pipe 31 is connected to the first air inlet 121 and the second air inlet 122 respectively through a connecting pipe. A first air inlet 121 is mounted on one side of the dust chamber 111, while a second air inlet 122 is mounted on the upper side of the dust chamber 111. The angle between the first air inlet 121 and the second air inlet 122 is 90°. Each of the first and second air inlets includes a rotating head 123 rotatably mounted on the dust chamber 111, and a plurality of air outlet pipes 124 disposed on the side of the rotating head 123 facing away from the dust chamber 111. Preferably, the plurality of air outlet pipes 124 extend vertically outward from the rotating head 123. The plurality of air outlet pipes 124 are equally spaced along the circumference of the rotating head 123. The angle between the air outlet pipes on the first air inlet 121 and the air outlet pipes on the second air inlet 122 is 90°. Each outlet pipe of the first air inlet head 121 is located between two adjacent outlet pipes of the corresponding second air inlet head 122. When the first air inlet head 121 rotates, the outlet pipes on the first air inlet head 121 drive the second air inlet head 122 to rotate. A driven member 126 is installed at the end of the first air inlet head 121 that protrudes from the dust chamber 111. Preferably, the driven member 126 is a gear. A gear that engages with the driven member 126 is installed on the first motor 125. When the first motor 125 operates, the driven member 126 drives the first air inlet head 121 to rotate, and the outlet pipes on the first air inlet head 121 drive the second air inlet head 122 to rotate. The flue gas ejected from the rotating first air inlet head 121 and the second air inlet head 122 collide with each other, reducing the flow velocity of the flue gas and making the velocity and direction of the flue gas uniform. Preferably, two sets of first air inlets 121 and second air inlets 122 are installed on the dust chamber 111. The two first air inlets 121 are connected by a belt drive mechanism. The flue gas to be dusted enters the dust chamber 111 through the first air inlet 121 and the second air inlet 122, and undergoes the first dust removal by the electrostatic precipitator 113. Preferably, the electrostatic precipitator 113 includes multiple electrostatic adsorption plates 114, which are staggered to allow the flue gas to flow along an S-shaped path, thereby extending the path of the flue gas flow. Larger particles are captured under the action of electrostatics, and the flue gas flow is adjusted to be uniform.In addition, a removable dust collection chamber 115 is installed on the lower side of the dust chamber 111. A grid plate is installed on the upper side of the dust collection chamber 115. Large particles can fall into the dust collection chamber 115 under the action of gravity, so as to prevent them from re-entering the electrostatic precipitator 113 with the flue gas. After a period of use, the user can remove the dust collection chamber 115 for cleaning. The flue gas after being filtered by the lower dust collection assembly 11 enters the upper dust collection assembly 12 through the pipe 116.
[0037] Also refer to Figure 4 , Figures 6 to 12 The upper dust removal assembly 12 includes a housing 21 supported on a dust chamber 111, a filter element 22 installed in the housing 21, a rotating assembly 23 disposed below the filter element 22, and a vibrating assembly 24 disposed above the filter element 22. The housing 21 is generally a hollow cylinder with its opening facing downwards. A through hole 213 is provided at the center of the upper end of the housing 21. A mounting sleeve 211 is disposed on the outer periphery of the through hole 213 and extends vertically downwards from the upper end of the housing 21. A protrusion 212 extending radially inwards along the inner side of the lower end of the housing 21 is provided. A dust collection chamber 214 is installed at the open end of the housing 21, and a dust collection pipe 215 is installed on the dust collection chamber 214, allowing dust falling into the dust collection chamber 214 to be discharged through the dust collection pipe 215. The filter element 22 is a filter cartridge, and the filtered flue gas flows out from the inner channel of the filter element 22. There is a gap between the outer periphery of the filter element 22 and the inner side of the housing 21. The filter element 22 has an outer ring 221 extending upward along its axial direction on its top edge. Two opposing triangular protrusions 223 are located on the inner side of the ring 221. Preferably, the included angle between the two protrusions 223 is 180°. A connecting pipe 224, communicating with an inner channel, is located at the center of the upper end of the filter element 22. The connecting pipe 224 is fitted into the mounting sleeve 211 and extends from the through hole 213. A bracket 222 is mounted on the lower side of the filter element 22. The filter element 22 is supported in the housing 21 by the bracket 222. Preferably, the bracket 222 includes multiple fan-shaped support ribs. More preferably, the multiple support ribs are evenly spaced along the circumference of the bracket 222. A rotating assembly 23 is located on the lower side of the bracket 222 and can seal the gaps between the support ribs.
[0038] The rotating assembly 23 includes a second motor 231 mounted on the housing 21, a gear mounted on the output shaft of the second motor 231, a gear ring 233 rotatably mounted in the housing 21 and driven by the gear, and a plurality of baffles 232 mounted on the inner side of the gear ring 233 and capable of sealing the gaps in the support 222. Preferably, the upper end of the gear ring 233 is provided with a groove 234, which engages with the protrusion 212 of the housing 21. After a period of use, dust accumulates on the filter element 22, requiring cleaning. During cleaning, the second motor 231 drives the gear ring 233 to rotate via the gear, causing the baffles 232 to rotate, thereby positioning the baffles 232 directly below the support ribs of the support 222, exposing the gaps between the support ribs, so that the dust accumulated on the filter element 22 falls into the dust collection chamber 214; then the vibration assembly 24 is activated, and the vibration assembly 24 strikes the filter element 22, causing the dust accumulated on the filter element 22 to fall off.
[0039] The vibration assembly 24 includes a third motor 41 mounted on the upper end of the housing 21, a drive gear 42 mounted in the housing 21, a first rotating member 43 rotatably mounted on the mounting sleeve 211, a second rotating member 44 rotatably mounted on the first rotating member 43, a fixed gear 45 fitted on the mounting sleeve 211, a third rotating member 46 rotatably mounted on the mounting sleeve 211, and a striking member 47 rotatably mounted on the second rotating member 44 and connected to the third rotating member 46. The first rotating member 43, the fixed gear 45, and the third rotating member 46 are arranged sequentially from top to bottom along the axial direction of the mounting sleeve 211. The drive gear 42 is mounted on the output shaft of the third motor 41. The first rotating member 43 includes a gear portion 431 engaging with the drive gear 42, a protrusion 432 provided on the lower side of the gear portion 431, and a support rod 433 extending radially outward from the outer side of the protrusion 432. The second rotating member 44 is rotatably mounted on the support rod 433, and rotates around the fixed gear 45 as the first rotating member 43 rotates. The second rotating member 44 is a gear that engages with the fixed gear 45. While rotating around the fixed gear 45, the second rotating member 44 also rotates on its own axis. The second rotating member 44 has an off-center mounting post. The third rotating member 46 includes a rotating sleeve 61 rotatably mounted on the mounting sleeve 211, and a connecting rod 62 extending radially outward along the rotating sleeve 61. The striking member 47 includes a striking member body 71, a connecting portion 72, and a striking hammer 73. Preferably, the striking member body 71 is generally Z-shaped. The connecting portion 72 is provided on one end of the striking member body 71 facing the second rotating member 44. Preferably, the connecting portion 72 has a first connecting hole and a second connecting hole. The connecting part 72 is rotatably connected to the mounting post of the second rotating member 44 through the first connecting hole, and is rotatably connected to the connecting rod 62 of the third rotating member 46 through the second connecting hole. The striking hammer 73 is disposed on the other end of the striking member body 71. Preferably, the striking hammer 73 is disposed on the side of the other end of the striking member body 71 facing away from the mounting sleeve 211.
[0040] In use, flue gas dust removal is performed by the first flue gas dust removal device 1 (at this time, the second flue gas dust removal device 2 is in a stopped or cleaning state). The flue gas undergoes the first dust removal in the lower dust removal assembly 11, and the flue gas after dust removal by the lower dust removal assembly 11 undergoes the second dust removal in the upper dust removal assembly 12. Specifically, the first motor 125 operates, and the driven member 126 drives the first air inlet head 121 to rotate. The air outlet pipe on the first air inlet head 121 drives the second air inlet head 122 to rotate. At the same time, the flue gas to be dusted enters the dust chamber 111 through the first air inlet head 121 and the second air inlet head 122, undergoes the first dust removal by the electrostatic dust removal assembly 113, and the flue gas after dust removal by the lower dust removal assembly 11 enters the upper dust removal assembly 12 through the pipe 116, undergoes the second dust removal by the filter element 22, and the filtered flue gas flows out from the inner channel of the filter element 22. After a period of use, the first flue gas dust removal device 1 is cleaned. At this time, the second flue gas dust removal device 2 is used for flue gas dust removal so that the flue gas can be continuously dusted without stopping the machine. When it is necessary to clean the filter element 22 of the first flue gas dust removal device 1, the second motor 231 drives the gear ring 233 to rotate through the gear, so that the baffle 232 rotates, so that the baffle 232 is located directly below the support rib of the bracket 222, exposing the gap between the support ribs, so that the dust accumulated on the filter element 22 falls into the dust collection chamber 214. Then the vibration component 24 is activated, and the vibration component 24 knocks the filter element 22, causing the dust accumulated on the filter element 22 to fall off. Specifically, the third motor 41 of the vibration assembly 24 drives the first rotating member 43 to rotate through the drive gear 42, causing the second rotating member 44 to rotate around the fixed gear 45. At the same time, the second rotating member 44 rotates on its own axis, and the striking member 47 on the second rotating member 44 drives the third rotating member 46 to rotate as the second rotating member 44 rotates. Under the combined action of the second rotating member 44 and the third rotating member 46, the striking member 47 swings around the mounting post on the second rotating member 44, so that the striking hammer 73 on the striking member 47 strikes the protrusion 223 of the filter element 22, causing the filter element 22 to vibrate, so that the dust accumulated on the filter element 22 falls into the dust collection chamber 214.
