Description

Technical Field

[0001] This invention relates to the field of flue gas recovery technology, and in particular to a fluid distribution control device. Background Technology

[0002] The high-temperature flue gas from the converter contains particulate matter, some of which are easily ignited by a source of ignition and pose an explosion risk. Therefore, it is necessary to capture the high-temperature flue gas to reduce the particulate content in the flue gas.

[0003] In existing technologies, particulate matter in flue gas is typically captured using a fully dry gravity settling device with an inclined plate structure. However, during the operation of a converter, the temperature of the flue gas produced is relatively high. This high temperature can affect the durability of various components in the fully dry gravity settling device, thus shortening its service life.

[0004] In addition, the inclined plate structure suffers from uneven smoke intake during use. Existing dry gravity settling equipment cannot uniformly input flue gas into the inclined plate structure, which reduces the capture effect of the inclined plate structure. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a fluid distribution control device for solving the problem of uneven flue gas distribution in order to improve the capture effect of flue gas particles.

[0016] In a preferred embodiment of the present invention, the latching part includes a latching block and a stop block. One end of the latching block is connected to the second plate body, and the other end of the latching block is connected to the stop block to form a T-shaped structure. The rectifier plate is latched onto the latching block through the latching slot.

[0017] In a preferred embodiment of the present invention, the second plate is inserted into the inner sleeve, and a wear-resistant structure is provided on the second plate. One end of the second plate is connected to the guide plate, and the other end of the second plate is folded to form the wear-resistant structure; or, a wear-resistant plate is attached to the second plate to form the wear-resistant structure.

[0018] In a preferred embodiment of the present invention, reinforcing ribs are provided between the first plate and the guide plate and / or between the guide plate and the second plate.

[0019] In a preferred embodiment of the present invention, multiple sets of the multi-layer flow guiding structure are provided at intervals along the circumference of the inner sleeve.

[0020] In a preferred embodiment of the present invention, the length of each fluid guide plate body is gradually reduced along the top-to-bottom direction.

[0021] In a preferred embodiment of the present invention, the fluid distribution control device further includes a water-cooled heat exchange component, which is disposed on the inner sleeve and is used to cool the flue gas.

[0022] In a preferred embodiment of the present invention, the water-cooled heat exchange assembly includes multiple water-cooled heat exchange tubes arranged at intervals along the circumference of the inner sleeve, with an installation gap formed between adjacent water-cooled heat exchange tubes, and the multi-layer flow guiding structure disposed in the installation gap.

[0023] In a preferred embodiment of the present invention, an installation structure is provided between the fluid guide plate and the water-cooled heat exchange assembly. The installation structure includes a first mounting member disposed on the water-cooled heat exchange tube and a second mounting member disposed on the water-cooled heat exchange tube. The second plate body passes through the inner sleeve and is connected to the first mounting member. The guide plate body of the fluid guide plate passes through the inner sleeve and is disposed in the collection cavity. The guide plate body is connected to or abuts against the second mounting member.

[0024] In a preferred embodiment of the present invention, the ash collection structure includes an ash collection hopper, which is disposed below the inclined plate settling structure, and the bottom of the ash collection hopper is provided with an ash outlet.

[0025] In a preferred embodiment of the present invention, the flue gas inlet and the ash outlet are disposed opposite to each other on both sides of the inclined plate settling structure.

[0026] The technical solution of the present invention has the following significant beneficial effects:

[0027] When the fluid distribution control device of the present invention is used, the flue gas to be treated is input into the inner sleeve from the flue gas inlet. After entering the inner sleeve, the flue gas is guided to the inclined plate settling structure along the various guide channels formed by the fluid guide plate clamping. The inclined plate settling structure can settle the particulate matter in the flue gas. Then, after being treated by the inclined plate settling structure, the flue gas is discharged from the flue gas outlet along the collection chamber, while the settled particulate matter falls into the ash collection structure along the inclined plate settling structure.

[0028] Specifically, the fluid guide plate structure of this invention includes a first plate, a guide plate body, and a second plate body. The second plate body can be installed on an inner sleeve to fix the fluid guide plate, and the guide plate body can be inclined upwards. In use, the resistance of each fluid guide plate to the flue gas can be changed by adjusting the size of the first and second included angles, as well as the length and area of ​​each plate body, thereby controlling the flow velocity of the flue gas through the guide channel. By controlling the flow velocity of the flue gas in each guide channel, the flow rate of the flue gas in each guide channel can be controlled, so that the flue gas can be evenly distributed into each guide channel, and then evenly guided to the inclined plate settling structure for settling operation. This avoids dead zones in the flue gas intake of the inclined plate settling structure, thus fully utilizing the settling performance of the inclined plate settling structure and improving the settling efficiency of the flue gas.

[0029] For example, when flue gas enters the flue gas inlet from top to bottom, it is gradually drawn out from the upper guide channel, and the flue gas pressure gradually decreases. This results in less flue gas entering the lower guide channel, leading to uneven flue gas distribution and dead zones in the inclined plate settling structure, preventing full utilization of its settling performance. To address these issues, the length of the guide plate can be gradually reduced from top to bottom, decreasing the apparent area of ​​the fluid guide plates and thus gradually reducing the flue gas resistance of each fluid guide plate. During use, when flue gas enters the inner sleeve through the flue gas inlet, the flue gas has a slower flow velocity along the guide channel due to the greater flue gas resistance of the upper fluid guide plate; while the flue gas resistance of the lower fluid guide plate is smaller, resulting in a faster flow velocity of the flue gas along the guide channel. By controlling the flue gas resistance of each fluid guide plate, uniform gas distribution can be achieved, thereby uniformly feeding the flue gas into the inclined plate settling structure and eliminating dead zones in flue gas distribution.

[0030] In particular, when multiple multi-layer flow guiding structures are set along the circumference of the inner sleeve, multiple flow guiding channels can be formed along the circumference of the inner sleeve through multiple multi-layer flow guiding structures. Then, the flue gas is evenly input into the inclined plate settling structure through multiple flow guiding channels, thereby making full use of the inclined plate settling structure for settling operation, significantly improving the treatment efficiency of flue gas and reducing particulate matter in the flue gas.

[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] Please refer to the following: Figures 1 to 12 This invention provides a fluid distribution control device, comprising: an inner sleeve 1 having an inner cavity 11 and a flue gas inlet 12; an outer sleeve 2 sleeved outside the inner sleeve 1, the outer sleeve 2 and the inner sleeve 1 clamping to form a collection cavity 21, the outer sleeve 2 having a flue gas outlet 22 communicating with the collection cavity 21; an inclined plate settling structure 3 disposed in the collection cavity 21 for collecting flue gas particles; an ash collection structure 4 disposed below the inclined plate settling structure 3; and a multi-layer flow guiding structure 5 disposed on the inner sleeve 1, the multi-layer flow guiding structure 5 comprising a plurality of fluid guide plates 51 arranged at intervals along the height direction, a flow guiding channel 52 being formed between adjacent layers of fluid guide plates 51, the flow guiding channel 52 communicating with the inner cavity 11 and the inclined plate settling structure 3.

[0061] Overall, when the fluid distribution control device is in use, the flue gas to be treated is input into the inner sleeve 1 through the flue gas inlet 12. After entering the inner sleeve 1, the flue gas is guided to the inclined plate settling structure 3 through the various guide channels 52 formed by the fluid guide plate 51. The inclined plate settling structure 3 can settle the particulate matter in the flue gas. Then, after being treated by the inclined plate settling structure 3, the flue gas is discharged from the flue gas outlet 22 through the collection chamber 21, while the settled particulate matter falls into the ash collection structure 4 along the inclined plate settling structure 3. The inclined plate settling structure 3 can adopt various structures in the prior art, such as a settling structure composed of multiple inclined plates, and there is no limitation here.

[0062] In the embodiments of the present invention, please refer to the following: Figures 1 to 6 The fluid guide plate 51 includes a guide plate body 511, a first plate body 512 connected to one end of the guide plate body 511, and a second plate body 513 connected to the other end of the guide plate body 511. The first plate body 512 and the second plate body 513 are disposed opposite to each other on both sides of the guide plate body 511. The first plate body 512 is disposed at a first angle a with the guide plate body 511, and the second plate body 513 is disposed at a second angle b with the guide plate body 511. The second plate body 513 is connected to the inner sleeve 1 for fixation, and a wear-resistant structure 55 is provided on the second plate body 513.

[0063] By adjusting the size of the first included angle a and the second included angle b, as well as the length and area of ​​each plate, the resistance of each fluid guide plate 51 to the flue gas can be changed, thereby controlling the flue gas flow rate in each guide channel 52. This allows the flue gas to be uniformly guided to the inclined plate settling structure 3 for settling, avoiding dead zones in the flue gas intake of the inclined plate settling structure 3, thus fully utilizing the settling performance of the inclined plate settling structure 3 and improving the settling efficiency of the flue gas.

[0064] Specifically, the first plate 512 can be positioned above the guide plate 511, and the second plate 513 can be positioned below the guide plate 511. During installation, the second plate 513 can be inserted into the inner sleeve 1 to fix it to the inner sleeve 1. The second plate 513 and the inner sleeve 1 can be fixed by welding, with a welding part provided on the inner sleeve 1, allowing the second plate 513 to be welded to the inner sleeve 1. Alternatively, the designer can use snap-fit ​​or other fixing methods to fix the second plate 513 to the inner sleeve 1; no limitation is made here.

[0065] The number of fluid guide plates 51 in the multi-layer flow guiding structure 5 can be determined by the total height of the inner sleeve 1. Along the height direction, the preferred spacing between adjacent fluid guide plates 51 is 300mm-600mm. The spacing between adjacent fluid guide plates 51 can be equal or unequal; no restriction is imposed here.

[0066] The angle between each guide plate 511 and the horizontal plane can be selected from 0° to 90°. Furthermore, the tilt angle of each guide plate 511 can be consistent with the tilt angle of the inclined plate in the inclined plate settlement structure 3, or the tilt angle of each guide plate can be approximately 10° plus or minus the tilt angle of the inclined plate. Wherein, the first included angle is the acute angle between the first plate 512 and the first surface, and the second included angle is the obtuse angle between the second plate 513 and the second surface.

[0067] Furthermore, the number of multi-layer flow guiding structures 5 can be determined by the circumferential diameter of the inner sleeve 1. The preferred range for the width of the fluid guide plate 51 is 50 mm to 200 mm. Along the direction of the flow guiding channel 52, the front and rear widths of the fluid guide plate 51 can be equal or unequal; no limitation is imposed here.

[0068] Furthermore, by controlling the setting height of the second plate body 513 of each fluid guide plate 51 and the setting length of the guide plate body 511 of each fluid guide plate 51, and by adjusting the size of the first included angle a and the second included angle b, the main viewing area of ​​the fluid guide plate 51 can be controlled, thereby adjusting the resistance to flue gas.

[0069] Specifically, the higher the first plate 512, the smaller the outlet area of ​​the guide channel 52, resulting in greater resistance and thus reducing the flue gas velocity. Similarly, the longer the guide plate 511, the larger its main visible area, leading to greater resistance and further reducing the flue gas velocity. However, a longer guide plate 511 also helps maintain the flue gas flow direction. Furthermore, the greater the height of the second plate 513, the smaller the inlet area of ​​the guide channel 52, resulting in greater resistance and further reducing the flue gas velocity. Designers can adjust the height and angle of the first plate 512, the second plate 513, and the guide plate 511 according to usage requirements to control the flue gas velocity, ensuring that the flue gas flows evenly into the inclined plate settling structure 3 along the fluid guide plates 51.

[0070] In the embodiments of the present invention, please refer to the following: Figures 9 to 12 The fluid guide plate 51 further includes a rectifier plate 53 disposed on the second plate body 513, and the rectifier plate 53 is disposed on the other side of the second plate body 513 relative to the first plate body 512.

[0071] Specifically, the rectifier plate 53 is disposed at the inlet of the guide channel 52, and can cover at least part of the inlet of the guide channel 52. By setting the rectifier plate 53 on the fluid guide plate 51, the rectifier plate 53 can further increase the flue gas resistance, thereby adjusting the flue gas velocity in the guide channel 52. By setting the fluid guide plate 51, the flue gas resistance can be adjusted in one step. By setting the rectifier plate 53 on the fluid guide plate 51, the flue gas resistance can be adjusted in two steps. Thus, by coordinating the two resistance adjustments, the resistance of the flue gas can be further controlled, thereby facilitating accurate control of the flue gas flow rate in the guide channel 52, so that the flue gas can flow evenly into each guide channel 52.

[0072] In an embodiment of the present invention, the rectifier plate 53 is provided with at least one flow hole 531 for allowing flue gas to pass through.

[0073] Specifically, the flow passage 531 can be configured as multiple circular through holes, which are evenly spaced and arranged on the rectifier plate 53. Alternatively, the flow passage 531 can be configured as at least two strip-shaped through holes, which are evenly spaced and arranged on the rectifier plate 53.

[0074] By providing flow holes 531 on the rectifier plate 53, the flow velocity of flue gas entering the guide channel 52 can be increased. The fluid guide plate 51 and the rectifier plate 53 generate two flue gas resistances, reducing the flue gas velocity. The flow holes 531 on the rectifier plate 53 facilitate flue gas passage, further increasing the flue gas velocity. Given a fixed flue gas resistance on the fluid guide plate 51, designers can further reduce the flue gas velocity by rationally configuring the rectifier plate 53 and the flow holes 531. The rectifier plate 53 can further reduce the flue gas velocity, while the flow holes 531 can increase it. By rationally configuring the specifications of the rectifier plate 53 and the flow holes 531, precise control of the flue gas resistance can be achieved, thereby controlling the flue gas flow rate within the guide channel 52, allowing the flue gas to flow evenly into the inclined plate settling structure 3 along each guide channel 52.

[0075] In an embodiment of the present invention, the rectifier plate 53 is connected to the second plate body 513 by a detachable structure. The detachable structure includes a snap-fit ​​portion 54 disposed on the second plate body 513 and a slot 532 disposed on the rectifier plate 53. The snap-fit ​​portion 54 is disposed away from the first plate body 512, and the rectifier plate 53 is snapped onto the snap-fit ​​portion 54 through the slot 532.

[0076] By detachably connecting the rectifier plate 53 to the second plate 513, different rectifier plates 53 can be replaced according to usage needs, thereby meeting the control requirements of different flue gas velocities.

[0077] Of course, designers can also use other connection methods between the rectifier board 53 and the second board 513, such as fixed connection or bonding, etc., without restriction.

[0078] In an embodiment of the present invention, the latching part 54 includes a latching block 541 and a stop block 542. One end of the latching block 541 is connected to the second plate 513, and the other end of the latching block 541 is connected to the stop block 542 to form a T-shaped structure. The rectifier plate 53 is latched onto the latching block 541 through the latching groove 532.

[0079] Specifically, the slot 532 is located at the bottom of the rectifier plate 53. Of course, designers can also use other snap-fit ​​structures to snap the snap-fit ​​part 54 and the rectifier plate 53 together, such as a snap-fit ​​structure, which is not limited here.

[0080] In an embodiment of the present invention, the second plate 513 is inserted into the inner sleeve 1, and a wear-resistant structure 55 is provided on the second plate 513. One end of the second plate 513 is connected to the guide plate 511, and the other end of the second plate 513 is folded to form the wear-resistant structure 55; or, a wear-resistant plate is attached to the second plate 513 to form the wear-resistant structure 55.

[0081] Because the flue gas contains particulate matter, when these particles flow into the guide channel 52, they impact the second plate 513 located in the inner sleeve 1, causing wear on the second plate 513 and thus reducing its service life. By providing a wear-resistant structure 55 on the second plate 513, direct impact from particulate matter can be prevented, thereby reducing wear and increasing its service life. Of course, designers can also enhance the service life of the second plate 513 by thickening it; this is not a limitation.

[0082] In an embodiment of the present invention, reinforcing ribs 56 are provided between the first plate 512 and the guide plate 511 and / or between the guide plate 511 and the second plate 513.

[0083] Because the fluid distribution control device generates vibration and high temperatures during operation, these factors accelerate material fatigue at the joints between the plates, increasing the risk of breakage and reducing the durability of the fluid guide plate 51. Adding reinforcing ribs 56 strengthens the connections between the plates, thereby improving the durability of the fluid guide plate 51. Of course, designers can also incorporate other reinforcing structures between the plates; this is not a limitation.

[0084] Specifically, both the fluid guide plate 51 and the reinforcing rib 56 can be made of heat-resistant steel plate with a thickness of not less than 3mm.

[0085] In an embodiment of the present invention, multiple sets of the multi-layer flow guiding structure 5 are arranged at intervals along the circumference of the inner sleeve 1.

[0086] By setting multiple sets of multi-layer flow guiding structures 5, the flue gas can be uniformly guided into the inclined plate settling structure 3 through the fluid guide plate 51 along the circumference of the inner sleeve 1, thereby making full use of the settling performance of the inclined plate settling structure 3 and improving the flue gas treatment efficiency.

[0087] When the flue gas enters the flue gas inlet 12 from top to bottom, the flue gas will be gradually discharged from the upper guide channel 52, and the pressure of the flue gas will gradually decrease, resulting in a gradual reduction of the flue gas entering the lower guide channel 52. This leads to uneven distribution of the flue gas and also causes the inclined plate settling structure 3 to have a dead angle for flue gas intake, making it impossible to fully utilize the settling performance of the inclined plate settling structure 3.

[0088] To address the aforementioned problems, in the embodiments of the present invention, please refer to the following: Figure 4 Along the direction from top to bottom, the length of the guide plate body 511 of each fluid guide plate 51 is gradually reduced.

[0089] Specifically, the guide plate body 511 is set in an upward tilt to create resistance to the flue gas. By reducing the length of the guide plate body 511, the main visible area of ​​the fluid guide plate 51 is gradually reduced, thereby gradually reducing the flue gas resistance of each fluid guide plate 51.

[0090] During use, when flue gas enters the inner sleeve 1 through the flue gas inlet 12, the flue gas has a slower flow velocity along the guide channel 52 due to the greater flue gas resistance of the upper fluid guide plate 51; while the flue gas resistance of the lower fluid guide plate 51 is smaller, resulting in a faster flow velocity of the flue gas along the guide channel 52. By controlling the flue gas resistance of each fluid guide plate 51, uniform gas distribution can be achieved, thereby uniformly feeding the flue gas into the inclined plate settling structure 3 and eliminating dead zones in flue gas distribution.

[0091] In an embodiment of the present invention, the fluid distribution control device further includes a water-cooled heat exchange component 6, which is disposed on the inner sleeve 1 and is used to cool the flue gas.

[0092] For details, please refer to the following: Figure 7 and Figure 8The water-cooled heat exchange assembly 6 includes multiple water-cooled heat exchange tubes 61 arranged at intervals along the circumference of the inner sleeve 1, with installation gaps formed between adjacent water-cooled heat exchange tubes 61. The multi-layer flow guiding structure 5 is disposed in the installation gaps. By uniformly arranging multiple water-cooled heat exchange tubes 61 on the inner sleeve 1, the flue gas can be cooled and its heat energy recovered, achieving energy saving and emission reduction.

[0093] In an embodiment of the present invention, an installation structure 7 is provided between the fluid guide plate 51 and the water-cooled heat exchange assembly 6. The installation structure 7 includes a first mounting member 71 disposed on the water-cooled heat exchange tube 61 and a second mounting member 72 disposed on the water-cooled heat exchange tube 61. The second plate body 513 passes through the inner sleeve 1 and is connected to the first mounting member 71. The guide plate body 511 of the fluid guide plate 51 passes through the inner sleeve 1 and is disposed in the collection cavity 21. The guide plate body 511 is connected to or abuts against the second mounting member 72.

[0094] Specifically, the first mounting member 71 and the second mounting member 72 are mounting ribs fixed at different positions on the water-cooled heat exchange tube 61, and the second plate body 513 of each fluid guide plate 51 can be welded to the first mounting member 71. Furthermore, when the guide plate body 511 of the fluid guide plate 51 is long, to prevent the guide plate body 511 from lacking support, it can be welded to the second mounting member 72, or the guide plate body 511 can be overlapped onto the second mounting member 72 for support.

[0095] An installation gap is formed by adjacent water-cooled heat exchange tubes 61, and a multi-layer flow guiding structure 5 is set in the installation gap. Each fluid guide plate 51 is directly fixed on the water-cooled heat exchange tube 61. Thus, multiple fluid guide plates 51 are used to divide the installation gap into the inlet of multiple flow guiding channels 52, which facilitates the entry of flue gas into the flow guiding channels 52, making the manufacturing process faster and more convenient.

[0096] Of course, designers can also adjust the fixing method of the fluid guide plate 51 according to the needs of use, and there are no restrictions here.

[0097] In an embodiment of the present invention, the ash collection structure 4 includes an ash collection hopper 41, which is disposed below the inclined plate settling structure 3, and the bottom of the ash collection hopper 41 is provided with an ash outlet 42.

[0098] By setting an ash collection hopper 41 below the inclined plate settling structure 3, particulate matter settling out of the flue gas can be collected, and the collected particulate matter is discharged from the ash outlet 42 for treatment.

[0099] Specifically, the flue gas inlet 12 and the ash outlet 42 are arranged opposite each other on both sides of the inclined plate settling structure 3. The flue gas inlet 12 is located above the ash outlet 42. After the particulate matter in the flue gas is captured by the inclined plate settling structure 3, it can fall into the ash collection hopper 41 under the action of gravity and be discharged along the ash outlet 42 for treatment.

[0100] In a specific embodiment of the fluid distribution control device of the present invention, the inner sleeve 1 can be set to DN2300mm, and 48 water-cooled heat exchange tubes 61 are provided on the inner sleeve 1. The water-cooled heat exchange tubes 61 are used as supports for installing the multi-layer flow guiding structure 5, and a multi-layer flow guiding structure 5 is provided between each adjacent water-cooled heat exchange tube 61.

[0101] The multi-layer flow guiding structure 5 may include nine fluid guide plates 51, with the interlayer spacing of each fluid guide plate 51 set to approximately 350 mm along the height direction. The guide plate body 511 of each fluid guide plate 51 is inclined upward, and the angle between the guide plate body 511 and the horizontal plane is set to approximately 45°.

[0102] Along the top-to-bottom direction, the angle between the first plate body 512 and the guide plate body 511 of the first fluid guide plate 51 and the second fluid guide plate 51 can be set to 180°, while the acute angle between the first plate body 512 and the guide plate body 511 of the third to ninth fluid guide plates 51 can be set to approximately 45°. The obtuse angle between the second plate body 513 and the guide plate body 511 of each fluid guide plate 51 can be set to approximately 135°.

[0103] In this embodiment, the height of the first plate body 512 of the first fluid guide plate 51 and the second fluid guide plate 51 can be set to approximately 150 mm, and the height of the second plate body 513 of the third and ninth fluid guide plates 51 can be set to approximately 100 mm. The length of the guide plate body 511 of the first and second fluid guide plates 51 can be set to 500 mm, the length of the guide plate body 511 of the third fluid guide plate 51 can be set to 400 mm, the length of the guide plate body 511 of the fourth fluid guide plate 51 can be set to 350 mm, and the length of the guide plate body 511 of the fifth to ninth fluid guide plates 51 can be set to 300 mm.

[0104] Along the conveying direction of the guide channel 52, the guide plate bodies 511 of the first and second fluid guide plates 51 can be configured to be narrower at the front and wider at the rear. Specifically, the front width of the guide plate body 511 can be set to 60mm, and the rear width of the guide plate body 511 can be set to 150mm. The third to ninth fluid guide plates 51 can be configured to be wider at the front and narrower at the rear. Specifically, the front width of the guide plate body 511 can be set to 110mm, and the rear width of the guide plate body 511 can be set to 50mm.

[0105] In this embodiment, the height of the wear-resistant structure 55 of the first to eighth fluid guide plates 51 can be set to about 50mm, while the ninth fluid guide plate 51 may not have a wear-resistant structure 55. Of course, designers can also adjust the specifications of each component according to usage needs, and there are no restrictions here.

[0106] When the fluid distribution control device of the present invention is used, the flue gas to be treated is input into the inner sleeve 1 from the flue gas inlet 12. After the flue gas enters the inner sleeve 1, it is guided to the inclined plate settling structure 3 along the various guide channels 52 formed by the fluid guide plate 51. The particulate matter in the flue gas can be settled by the inclined plate settling structure 3. Then, after the flue gas is treated by the inclined plate settling structure 3, it is discharged from the flue gas outlet 22 along the collection chamber 21, while the settled particulate matter falls into the ash collection structure 4 along the inclined plate settling structure 3.

[0107] The fluid distribution control device of this invention can change the resistance of each fluid guide plate 51 to the flue gas by adjusting the size of the first included angle α and the second included angle b, as well as the length and area of ​​each plate, thereby controlling the flow velocity of the flue gas through the guide channel 52. By controlling the flow velocity of the flue gas in each guide channel 52, the flow rate of the flue gas in each guide channel 52 can be controlled, so that the flue gas can be evenly distributed into each guide channel 52, and then evenly guided to the inclined plate settling structure 3 for settling operation through the guide channel 52. This avoids the presence of dead zones for flue gas intake in the inclined plate settling structure 3, thus fully utilizing the settling performance of the inclined plate settling structure 3 and improving the settling efficiency of the flue gas.
