DETAILED DESCRIPTION

[0020] In order to make the skilled in the art better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0021] Please refer to Figures 1-12 The embodiment of the present application provides a technical solution: a production dust removal equipment, comprising a box 1, which is provided with a dust removal cavity 11 and air inlet pipes 12 and air outlet pipes 13 connected with both ends of the dust removal cavity 11, a dust storage box 21 and a baffle 22 symmetrically shielding the opening of the dust storage box 21 are linearly arrayed in the dust removal cavity 11, and a filter screen plate group is linearly arrayed in the dust removal cavity 11, the filter screen plate group comprises a first filter plate 31 and a second filter plate 32 arranged in a moustache shape, the wide mouth ends of the first filter plate 31 and the second filter plate 32 are both directed to the baffle 22, a through slot 311 is formed on one side of the narrow mouth end of the first filter plate 31 and the second filter plate 32, and the waist side of the filter screen plate group is directed to the air inlet pipes 12 and the air outlet pipes 13.

[0022] Preferably, as Figure 2As shown, the air inlet pipe 12 and the air outlet pipe 13 are respectively communicated to the horizontal two ends of the dust removal cavity 11, and a plurality of through grooves are formed in the bottom of the dust removal cavity 11, and the dust storage box 21 can be installed into the through grooves so that the dust storage box 21 is located at the bottom side of the dust removal cavity 11, and the baffle 22 is inclined to partially block the opening of the dust storage box 21, and the filter screen plate groups are linearly arranged in the dust removal cavity 11, and each group of filter screen plates is aligned with the dust storage box 21, such as Figure 2 As shown, the end of the first filter plate 31 and the second filter plate 32 towards the dust storage box 21 is a wide opening end, and the end of the first filter plate 31 and the second filter plate 32 away from the dust storage box 21 is a narrow opening end, and a through groove 311 is formed in the narrow opening end of the first filter plate 31, and the wide opening end of the first filter plate 31 and the second filter plate 32 are all towards the baffle 22, and the waist side of the first filter plate 31 and the second filter plate 32 are respectively the air inlet pipe 12 and the air outlet pipe 13.

[0023] When the flue gas flows through the dust removal cavity 11 from the air inlet pipe 12 and is discharged from the air outlet pipe 13, as shown, Figure 12 The flue gas sequentially passes through a plurality of groups of first filter plates 31 and second filter plates 32 to filter and remove dust particles in the flue gas, and the dust particles can be divided into large particle dust, medium particle dust and small particle dust according to volume, and the flow direction of the flue gas is not perpendicular to the surface of the first filter plate 31 and the second filter plate 32, when the flue gas flows through the first filter plate 31, the large particle dust is easy to roll along the surface of the first filter plate 31 and directly fall into the dust storage box 21 due to its large weight, the small particle dust is filtered by the first filter plate 31 and is trapped on the surface of the first filter plate 31, and the medium particle dust is difficult to be trapped on the surface of the first filter plate 31 due to its large volume, so that the medium particle dust is rolled along the surface of the first filter plate 31 and flows from the through groove 311 to the second filter plate 32, and then the flue gas drives the medium particle dust to roll along the surface of the second filter plate 32, and the medium particle dust is separated from the flue gas by inertia and hits on the baffle 22, and then the medium particle dust rolls along the baffle 22 and falls into the dust storage box 21 to be collected, thereby completing the filtration and collection of different volume particles in the flue gas and improving the removal efficiency of dust particles.

[0024] And the first filter plate 31 and the second filter plate 32 are inclined to guide the flue gas in the dust removal cavity 11 to flow and discharge to the air outlet pipe 13, when the first filter plate 31 and the second filter plate 32 are accumulated with too much dust particles and the air flow resistance increases, the flue gas is avoided from vertically impacting on the surface of the first filter plate 31 and the second filter plate 32, thereby avoiding the problem of secondary dust raising caused by the flue gas flowing along the direction of the second filter screen plate surface due to the air flow pressure impacting the dust removal box, and also reducing the air flow resistance in the dust removal operation and improving the dust removal efficiency of the dust in the flue gas.

[0025] The first filter plate 31 and the second filter plate 32 are each provided with a filter plate portion 91. The filter plate portion 91 is located in the dust removal chamber 11 in an inclined position, and the waist side of the filter plate portion 91 faces the air inlet pipe 12 and the air outlet pipe 13.

[0026] Furthermore, backflushing gas can be drawn from the exhaust pipe 13 into the dust removal chamber 11 and discharged from the exhaust pipe 13, thereby backflushing and cleaning the filter plate assembly in the dust removal chamber 11. At this time, the cleaning gas first passes through the second filter plate 32 and then flows through the first filter plate 31, thereby removing the dust adhering to the filter plate assembly. Due to the airflow pressure, the cleaning gas will also flow along the plate surface of the second filter plate 32 to the narrow end of the second filter plate 32, thereby increasing the airflow resistance of the second filter plate 32 and improving the cleaning effect on the second filter plate 32.

[0027] In the above technical solution, the first filter plate 31 and the second filter plate 32 are both inclined to guide the flue gas in the dust removal chamber 11 to flow and be discharged through the outlet pipe 13. When too many dust particles accumulate on the first filter plate 31 and the second filter plate 32 and the airflow resistance increases, the flue gas is prevented from vertically impacting the surfaces of the first filter plate 31 and the second filter plate 32. This avoids the problem of secondary dust generation caused by the airflow pressure causing the flue gas to flow along the second filter plate surface and impact the dust removal box. It also reduces the airflow resistance in the dust removal operation and improves the dust removal efficiency of the flue gas.

[0028] In another embodiment of the present invention, a movable plate 4 is slidably disposed in the dust removal chamber 11. The movable plate 4 has an extension groove 41 and a connecting groove 421 linearly arranged on it. The first filter plate 31 and the second filter plate 32 are located on the narrow end side, pass through the extension groove 41 and are rotatably disposed on the housing 1, and are connected to the connecting groove 421 through the groove 311. The movable plate 4 slides to push the first filter plate 31 and the second filter plate 32 to swing relative to each other.

[0029] Preferred, such as Figure 2 As shown, the movable plate 4 is vertically slidably disposed in the dust removal chamber 11, and the movable plate 4 is linearly arrayed with a mounting part 42. The mounting part 42 is provided with a connecting groove 421, and the narrow ends of the first filter plate 31 and the second filter plate 32 pass through the extension groove 41 and are rotatably connected to the housing 1, while the filter plate part 91 of the first filter plate 31 and the second filter plate 32 is still located in the dust removal chamber 11.

[0030] When the movable plate 4 is driven to slide closer to the narrow ends of the first filter plate 31 and the second filter plate 32, the extension groove 41 will compress the first filter plate 31 and the second filter plate 32 to swing away from each other, thereby reducing the installation tilt of the first filter plate 31 and the second filter plate 32. Conversely, when the movable plate 4 is driven to slide away from the narrow ends of the first filter plate 31 and the second filter plate 32, the extension groove 41 will compress the first filter plate 31 and the second filter plate 32 to swing closer to each other, thereby increasing the installation tilt of the first filter plate 31 and the second filter plate 32.

[0031] Since the air inlet pipe 12, dust removal chamber 11 and air outlet pipe 13 are arranged horizontally, when the installation inclination of the first filter plate 31 and the second filter plate 32 increases, the angle between the first filter plate 31 and the second filter plate 32 and the vertical line decreases, thereby increasing the flow resistance of the first filter plate 31 and the second filter plate 32 to the flue gas and improving the filtration efficiency of small dust particles in the flue gas.

[0032] When the installation inclination of the first filter plate 31 and the second filter plate 32 decreases, the angle between the first filter plate 31 and the second filter plate 32 and the vertical line increases, which reduces the flow resistance of the first filter plate 31 and the second filter plate 32 to the flue gas. Although the filtration efficiency for small dust particles in the flue gas is reduced, the increased flue gas velocity can improve the removal efficiency of the first filter plate 31 and the second filter plate 32 for medium and large dust particles.

[0033] Therefore, before carrying out actual dust removal operations, the volume distribution of dust particles in the flue gas to be treated can be estimated first. Then, based on the volume distribution of dust particles, the tilt of the first filter plate 31 and the second filter plate 32 can be adjusted by the movable plate 4 to improve the dust removal efficiency of the flue gas.

[0034] like Figure 9 As shown, several flexible sealing elements 93 are also provided on the movable plate 4. The sealing elements 93 are used to prevent dust in the dust removal chamber 11 from entering the interior of the box 1 through the extension groove 41.

[0035] In another embodiment of the present invention, a support seat 5 is movably arranged on the housing 1. The two ends of the support seat 5 are respectively provided with protrusions 51 for bolting to the housing 1. Abutment ears 44 are symmetrically arranged on the movable plate 4, and the support seat 5 is supported on the bottom of the abutment ears 44.

[0036] Preferred, such as Figure 5As shown, both ends of the support 5 are provided with protrusions 51, and threaded holes are opened on the protrusions 51. The support 5 can slide freely vertically on the housing 1. The operator can first manually drive the movable plate 4 to slide to adjust the installation tilt of the first filter plate 31 and the second filter plate 32, thereby adjusting the dust removal efficiency of the filter plate assembly for particles of different volumes in the flue gas. Then, the support 5 supports the contact ear 44, and then the bolt is installed into the threaded hole and abuts against the housing 1, thereby completing the fixation between the support 5 and the housing 1. At this time, the support 5 can support and limit the movable plate 4, thereby completing the manual adjustment and fixation of the installation tilt of the filter plate assembly, which is convenient for actual dust removal operation.

[0037] In another embodiment of the present invention, a rotating roller 6 is rotatably arranged in the groove 311, and a third filter plate 61 is fixedly arranged in a circumferential array on the rotating roller 6. The rotating roller 6 is driven to rotate so that the third filter plate 61 blocks the connecting groove 421 at intervals.

[0038] Preferred, such as Figure 2 As shown, the rotating roller 6 is rotatably disposed in the connecting groove 421 of the movable plate 4, and when the rotating roller 6 rotates, a number of third filter plates 61 can rotate sequentially to abut against the side wall of the connecting groove 421, thereby blocking the connecting groove 421 by the third filter plates 61, and the filter screen aperture of the third filter plate 61 is larger than that of the filter plate part 91.

[0039] When flue gas flows through the first filter plate 31, large dust particles, due to their greater weight, easily roll along the surface of the first filter plate 31 and fall directly into the dust collection box 21. Small dust particles are filtered by the first filter plate 31 and become trapped on its surface. Medium-sized dust particles, being larger, are less likely to become trapped on the surface of the first filter plate 31. As a result, medium-sized dust particles are carried by the flue gas and roll along the surface of the first filter plate 31, entering the passage groove 311 and the connecting groove 421. At this point, the medium-sized dust particles are filtered and intercepted in the connecting groove 421 by the third filter plate 61. This causes the third filter plate 61 to increase the flow resistance in the connecting groove 421 until the airflow pressure in the connecting groove 421 can drive the rotating roller 6 to rotate. The rotating roller 6 rotates so that the third filter plate 61 rotates away from the connecting groove 421. The medium-sized dust particles intercepted on the connecting groove 421 are blown by the airflow and move closer to the second filter plate 32. Then the rotating roller 6 rotates until another third filter plate 61 rotates and moves to contact the side wall of the connecting groove 421, so that the third filter plate 61 blocks the connecting groove 421 again to intercept dust particles.

[0040] The presence of the rotating roller 6 and the third filter plate 61 intercepts and slows down medium-sized dust particles rolling along the surface of the first filter plate 31. After a certain amount of medium-sized dust particles accumulate, they are discharged towards the second filter plate 32. This avoids the problem of severe wear on the second filter plate 32 caused by the medium-sized dust particles being accelerated by the airflow and directly impacting it, thus improving the service life of the second filter plate 32. Secondly, medium-sized dust particles tend to agglomerate during the accumulation process, which further facilitates the inertial filtration of medium-sized dust particles and improves the dust removal efficiency of the flue gas.

[0041] In another embodiment of the present invention, a movable block 7 and an elastic element 8 are also included. The two ends of the elastic element 8 are fixedly connected to the housing 1 and the movable block 7 respectively to pull the movable block 7 closer to the housing 1. A pushing part 62 is arranged in a circular array on the rotating roller 6. The rotating roller 6 is driven to rotate so that the pushing part 62 pushes the movable block 7 and jams it on the movable plate 4.

[0042] Preferably, the movable plate 4 has a movable cavity 45, the pushing part 62 of the rotating roller 6 is located in the movable cavity 45, and the movable block 7 is aligned with the movable cavity 45.

[0043] When medium-sized dust particles are carried by flue gas and roll along the surface of the first filter plate 31 and enter the through groove 311 and the connecting groove 421, the medium-sized dust particles are filtered and intercepted in the connecting groove 421 by the third filter plate 61, thereby increasing the flow resistance in the connecting groove 421 until the air pressure in the connecting groove 421 can drive the rotating roller 6 to rotate, first discharging the medium-sized dust particles in the connecting groove 421 to the second filter plate 32; When the rotating roller 6 rotates, it also drives several pushing parts 62 to rotate synchronously, so that the pushing parts 62 can push the movable block 7 to be stuck on the movable plate 4. Then, the elastic member 8 pulls the movable block 7 and the movable plate 4, so that the movable plate 4 slides closer to the narrow end of the first filter plate 31 and the second filter plate 32. At this time, the movable plate 4 will push the first filter plate 31 and the second filter plate 32 away from each other to reduce the installation tilt of the first filter plate 31 and the second filter plate 32, thereby instantly increasing the airflow velocity in the dust removal chamber 11. This allows the flue gas to first discharge medium-sized dust particles from the connecting groove 421 to the second filter plate 32 at a low speed. Then, the flue gas accelerates to increase the rolling speed of the medium-sized dust particles along the surface of the second filter plate 32, thereby increasing the impact momentum of the medium-sized dust particles when separating from the airflow and improving the separation efficiency of the medium-sized dust particles and the flue gas.

[0044] When the content of medium-sized dust particles in the flue gas is relatively high, the accumulation rate of medium-sized dust particles in the connecting groove 421 and on the third filter plate 61 is relatively fast. Therefore, the rotation speed of the roller 6 is relatively fast, which allows the pushing part 62 to repeatedly push the movable block 7 to be stuck on the movable plate 4. In turn, the movable plate 4 is pulled by the elastic member 8 to keep the first filter plate 31 and the second filter plate 32 in a position with reduced installation inclination. This realizes that the first filter plate 31 and the second filter plate 32 can adaptively adjust the installation inclination according to the volume distribution of dust particles in the flue gas, thereby improving the dust removal efficiency in the flue gas.

[0045] In another embodiment of the present invention, a guide slide 14 is fixedly provided on the housing 1, an extension 43 is fixedly provided on the movable plate 4, a limiting slope 431 is provided on the extension 43, and a pushing part 62 pushes the movable block 7 so that the contact slope 71 provided on the movable block 7 contacts the limiting slope 431. After the pushing part 62 separates from the movable block 7, the movable block 7 slides along the contact slope 71 until it contacts the guide slide 14. The movable plate 4 slides back to its original position under gravity so that the contact slope 71 presses down on the movable block 7 and locks it at the end of the guide slide 14.

[0046] Preferred, such as Figure 8 As shown, an abutment slope 71 is provided on the movable block 7, and a limiting slope 431 is provided on the extension 43 of the movable plate 4. For example... Figure 10 As shown, the movable block 7 is located at the end of the guide slide 14 in the default state. When medium-sized dust particles are carried by the flue gas, they roll along the surface of the first filter plate 31 and enter the through groove 311 and the connecting groove 421. The medium-sized dust particles are filtered and intercepted in the connecting groove 421 by the third filter plate 61, which in turn increases the flow resistance in the connecting groove 421 until the airflow pressure in the connecting groove 421 can drive the rotating roller 6 to rotate, first discharging the medium-sized dust particles in the connecting groove 421 to the second filter plate 32. When the rotating roller 6 rotates, the pushing part 62 rotates clockwise synchronously, so that the pushing part 62 can push the movable block 7 to move and contact the movable plate 4. At this time, the contact slope 71 of the movable block 7 contacts the limiting slope 431 of the movable plate 4. At this time, the pushing part 62 presses the movable block 7 tightly and locks it on the movable plate 4. That is, the elastic member 8 applies a vertical lifting force to the movable plate 4 through the movable block 7. The elastic member 8 pulls the movable block 7 and the movable plate 4 to slide closer to each other relative to the narrow ends of the first filter plate 31 and the second filter plate 32.

[0047] As the roller 6 continues to rotate, causing the pushing part 62 to rotate away from the movable block 7, the elastic element 8 pulls the movable block 7 to slide along the limiting slope 431 until it contacts the guide slide 14. However, the contact slope 71 remains in contact with the limiting slope 431. At this time, the elastic element 8 applies a vertical lifting force and a horizontal squeezing force to the movable plate 4 through the movable block 7, thereby reducing the vertical lifting force on the movable plate 4. The movable plate 4 is then driven by its own weight to slide vertically downward and move away from the narrow ends of the first filter plate 31 and the second filter plate 32. Simultaneously, the extension 43 of the movable plate 4 also squeezes the movable block 7 to slide back to its default position at the end of the guide slide 14. Thus, the vertical sliding and resetting of the movable plate 4 are achieved by using the movable block 7, the elastic element 8, and the extension 43 of the movable plate 4, without the need for an additional drive source, improving the stability of the device.

[0048] In another embodiment of the present invention, the movable block 7 is provided with a contact arc groove 72, the end of the pushing part 62 is arc-shaped, the rotating roller 6 rotates so that the pushing part 62 abuts against the contact arc groove 72 to push the movable block 7 to move, and after the movable block 7 abuts against the movable plate 4, the pushing part 62 rotates away from the contact arc groove 72.

[0049] Preferred, such as Figure 10 As shown, the end of the pushing part 62 is arc-shaped, and the movable block 7 is provided with a contact arc groove 72. When medium-sized dust particles are carried by the flue gas, they roll along the surface of the first filter plate 31 and enter the through groove 311 and the connecting groove 421. The medium-sized dust particles are filtered and intercepted in the connecting groove 421 by the third filter plate 61, thereby increasing the flow resistance in the connecting groove 421 until the airflow pressure in the connecting groove 421 can drive the rotating roller 6 to rotate clockwise, first discharging the medium-sized dust particles in the connecting groove 421 to the second filter plate 32. When the rotating roller 6 rotates, the pushing part 62 rotates clockwise simultaneously, allowing the pushing part 62 to contact the contact arc groove 72 of the movable block 7. At this time, the rotating roller 6 rotates under the pressure of the airflow, causing the pushing part 62 to push the movable block 7 closer to the extension 43 and squeeze and jam the pushing part 62 onto the movable plate 4. At this time, the arc-shaped end of the pushing part 62 coincides with the inner wall of the contact arc groove 72 of the movable block 7, so that the rotating roller 6 can continue to rotate clockwise to make the pushing part 62 rotate away from the contact arc groove 72, thereby unlocking the movable block 7 from the movable plate 4.

[0050] When backflushing gas flows from the exhaust pipe 13 into the dust removal chamber 11 and exits through the exhaust pipe 13, the clean gas first passes through the second filter plate 32 and then flows through the first filter plate 31, thereby removing the dust adhering to the filter plate assembly. The airflow pressure also applies a counterclockwise rotation driving force to the rotating roller 6 through the connecting groove 421. When the pushing part 62 rotates counterclockwise to contact the movable block 7, the movable block 7 will block the rotating roller 6, thereby achieving unidirectional rotation of the rotating roller 6. At this time, some dust particles will accumulate on the third filter plate 31 during the backflushing dust removal operation. The filter plate 61 is located near the outlet pipe 13. As the clean gas flows at high speed from the narrow end to the wide end of the first filter plate 31, the velocity difference between the surface of the first filter plate 31 and the connecting groove 421 will draw out the dust accumulated in the connecting groove 421 and roll along the first filter plate 31 into the dust collection box 21. This avoids the problem of dust accumulated in the connecting groove 421 rushing out at high speed along the connecting groove 421 during backwashing cleaning, causing impact wear on the second filter plate 32, and improves the protection of the second filter plate 32.

[0051] In another embodiment of the present invention, a limiting part 141 with a slope is symmetrically arranged on the guide slide 14, and a through slope 73 is provided on the movable block 7, which is aligned with the limiting part 141.

[0052] Preferred, such as Figure 11 As shown, the limiting part 141 on the guide slide 14 has a slope. In the default state, the end of the movable block 7 abuts against the limiting part 141 and is located at the end of the guide slide 14. At this time, the movable block 7 is in the default state. When the movable plate 4 is driven by its own weight to slide vertically downward and move away from the narrow end of the first filter plate 31 and the second filter plate 32, the extension part 43 of the movable plate 4 also squeezes the movable block 7 to slide. The movable block 7 passes through the slope 73 and squeezes over the limiting part 141 so that the movable block 7 can move back to the default position, realizing the stable reset and locking of the movable block 7, which facilitates the disengagement and locking of the movable block 7 and the movable plate 4, and improves the operating stability of the device.

[0053] In another embodiment of the present invention, movable columns 411 are symmetrically arranged on the extension groove 41, and movable grooves 92 are symmetrically opened on the first filter plate 31 and the second filter plate 32, with the movable columns 411 movably arranged in the movable grooves 92.

[0054] Preferred, such as Figure 6As shown, movable columns 411 are symmetrically arranged in the extension groove 41, and movable grooves 92 are opened on both sides of the first filter plate 31 and the second filter plate 32. When the narrow ends of the first filter plate 31 and the second filter plate 32 pass through the extension groove 41 and are rotatably connected to the housing 1, the movable columns 411 are movably arranged in the movable grooves 92. This allows the movable columns 411 to move within the movable grooves 92 when the movable plate 4 pushes against the first filter plate 31 and the second filter plate 32 and swings relative to each other, thereby improving the swing stability of the first filter plate 31 and the second filter plate 32.

[0055] Working principle: S1. First, estimate the volume distribution of dust particles in the flue gas to be treated. S2. Adjust the height of the fixed support 5 according to the volume distribution of dust particles, so that the movable plate 4 can slide to change the installation inclination of the first filter plate 31 and the second filter plate 32. Then, fix the support 5 to the box 1 with bolts. S3. Flue gas is introduced into the dust removal chamber 11 through the inlet pipe 12. The flue gas passes through multiple sets of first filter plates 31 and second filter plates 32 in sequence to filter dust particles. When too much dust accumulates on the first filter plates 31 and second filter plates 32 and the flow resistance is too high, the flue gas flows along the surface of the first filter plate 31 from the through groove 311 and the connecting groove 421 to the second filter plate 32. Then the flue gas flows along the surface of the second filter plate 32 and over the second filter plate 32 to flow to the next set of filter screens. S4. Subsequently, the flue gas is discharged from the exhaust pipe 13 and then passes through the spray scrubbing tower and electrostatic precipitator in sequence to complete the dust removal operation of the flue gas.

[0056] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
