[0013] Furthermore, a second inlet is provided on the lower side of the housing, which communicates with the interior of the hollow shaft; a fixing seat is fixed on the outer circumferential surface of the hollow shaft, and an air nozzle is installed on the fixing seat, which communicates with the interior of the hollow shaft.

[0014] Furthermore, a smoke inlet is fixedly provided at the top of the shell, and a first atomizer is provided inside the smoke inlet.

[0024] (2) The enthalpy reduction flue gas dust removal and deodorization device and process, by setting a reversing component and fixing teeth on the upper and lower cover plates, cooperates with the valve body assembly, upper piston body and lower piston body to realize the reciprocating swing of the upper and lower cover plates and the switching of the valve body assembly, avoids the backflow of the mixture, and allows the mixture to continuously enter the pressure chamber for full pressurization and mixing, thereby improving the efficiency and stability of the treatment.

[0025] (3) The enthalpy reduction flue gas dust removal and deodorization device and process first capture large solid particles in the flue gas by using water mist and turbulence through the mixing chamber and the first atomizer.

[0049] 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.

[0050] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0051] The following is based on Figure 1 - Figure 20 This invention describes an enthalpy-reduction flue gas dust removal and deodorization device and process provided by an embodiment of the present invention.

[0052] like Figure 1-10 As shown, an enthalpy reduction flue gas dust removal and deodorization device includes a housing 1 and a straight cylinder 8. Multiple straight cylinders 8 are arranged in a circumferential array inside the housing 1. Six straight cylinders are shown in the figure. A lower support plate 18 is fixedly installed on the lower side inside the housing 1. The lower end of the straight cylinder 8 is fixedly installed on the lower support plate 18. The flue gas to be treated enters the straight cylinder 8 from the upper side and is discharged from the exhaust pipe 26 on the lower side of the straight cylinder 8.

[0053] Furthermore, a second atomizer 25 is fixed at the top of the straight cylinder 8. The second atomizer 25 is used to introduce atomized deodorizing liquid into the straight cylinder 8. The atomized particle size of the deodorizing liquid is in the range of 10-50μm, so as to fully mix and react with the odor-producing substances to generate solid particles.

[0054] A pressure chamber 54 is also fixed on the inner wall of the straight cylinder 8. The pressure chamber 54 serves as a mixing place for the atomized deodorizing liquid and the flue gas. The pressure chamber 54 has multiple sub-cavities 55. The volume of the multiple sub-cavities 55 gradually decreases from the outer periphery to the center along the radial direction of the straight cylinder 8. This is used to gradually pressurize the flowing mixture, thereby compressing the volume of the mixture and increasing the kinetic energy of the deodorizing liquid, so that the flue gas and the deodorizing liquid can be fully contacted and the reaction effect can be improved.

[0055] like Figure 7 - Figure 10 As shown, an upper cover plate 52 and a lower cover plate 53 are rotatably provided on the upper and lower end faces of the pressure chamber 54 to enclose and form a main chamber. The mixture enters the main chamber from the outer peripheral side of the upper cover plate 52 and is discharged from the inner peripheral side of the lower cover plate 53.

[0056] Specifically, a support frame 51 is fixedly installed on the inner wall of the straight cylinder 8. A hollow shaft 32 is also provided vertically at the axis of the straight cylinder 8. The upper cover plate 52 is rotatably connected to the hollow shaft 32. The pressure cavity 54 is fixedly connected to the inner wall of the support frame 51 by a rod. The inner side wall of the pressure cavity 54 is connected to the hollow shaft 32 by a second fixing rod 29. Specifically, a first bushing 89 is rotatably provided on the outer circumferential surface of the hollow shaft 32. One end of the second fixing rod 29 is fixedly connected to the pressure cavity 54, and the other end is fixedly connected to the first bushing 89. One end of the lower cover plate 53 is supported by the support frame 51 and rotatably connected to it. The other end is rotatably connected to the hollow shaft 32 by a third fixing rod. A second bushing 90 is rotatably provided on the outer circumferential surface of the hollow shaft 32. One end of the third fixing rod 30 is fixedly connected to the second bushing 90, and the other end is fixedly connected to the lower cover plate 53, thereby leaving an exhaust chamber between the lower cover plate 53 and the hollow shaft 32 for the mixture to flow through. An opening is left on the side of the upper cover plate 52 near the outer circumference, and a gap space is left between the outer wall of the pressure chamber 54 and the inner wall of the support frame 51 as an air inlet chamber 88, so that the mixture enters the main chamber from the air inlet chamber 88 and is discharged from the exhaust chamber, so that the mixture can flow radially when passing through the main chamber, increasing the flow distance of the mixture in the straight cylinder 8, thereby increasing the pressurized mixing time of flue gas and deodorizing liquid.

[0057] Furthermore, the pressure chamber 54 is composed of multiple annular partitions 541 and radial partitions 542. The multiple annular partitions 541 are arranged concentrically along the same central axis and at equal intervals. The multiple radial partitions 542 are arranged in a circular array around the central axis. The annular partitions 541 and radial partitions 542 are interconnected and together divide the main chamber into multiple sub-cavities 55 distributed circumferentially and radially. The sub-cavities 55 closer to the central axis are smaller in volume. In the figure, there are 4 annular partitions 541 and 12 radial partitions 542. Of course, the number of both can be varied according to the actual situation.

[0058] Furthermore, a valve body assembly is provided at the intersection of the annular partition 541 and the radial partition 542 to change the on / off state of the two sub-cavities 55 on both sides of the valve body assembly along the circumferential direction. Specifically, at the same time, for the four sub-cavities 55 surrounding a single valve body assembly, with the radial partition 542 as the dividing line, the two sub-cavities 55 on the same side of the radial partition 542 are in the same group. At the same time, only one group of the two groups of cavities is in the connected state. When the state of the valve body assembly changes, the on / off state of the two groups of cavities also changes accordingly.

[0059] Furthermore, an upper piston body 58 is fixedly provided on the lower end face of the upper cover plate 52, and the upper piston body 58 is located in the sub-cavity 55 of the first ring. A lower piston body 59 is fixedly provided on the upper end face of the lower cover plate 53, and the lower piston body 59 is located in the sub-cavity 55 of the second ring. The first ring and the second ring are staggered in the radial direction. Here, the first ring and the second ring are sub-cavities 55 located at different radii. The upper piston body 58 and the lower piston body 59 are used to divide the space inside the corresponding sub-cavities 55 into two parts to serve as a gas storage chamber and an exhaust chamber.

[0060] In addition, a first drive assembly is provided inside the straight cylinder 8 to drive the upper cover plate 52 and the lower cover plate 53 to swing back and forth, and to make the upper cover plate 52 and the lower cover plate 53 swing in opposite directions and at the same swing angle, thereby driving the upper piston body 58 and the lower piston body 59 to push the flue gas flow in the corresponding sub-cavities 55. Furthermore, since the sub-cavities 55 closer to the hollow shaft 32 have smaller volumes, the mixture is compressed during the flow process.

[0061] It should be noted that, since the upper cover plate 52 and the lower cover plate 53 move in opposite directions, the upper piston body 58 and the lower piston body 59 are positioned differently in their respective sub-cavities 55, so that they can reciprocate simultaneously in their respective sub-cavities 55, with their directions of movement being opposite.

[0062] like Figure 9 - Figure 11 As shown, in order to make the upper cover plate 52 and the lower cover plate 53 swing in opposite directions and with the same swing angle, a reversing component is provided between the upper cover plate 52 and the lower cover plate 53. The reversing component includes a lower conical tooth section 61, which is fixed to the upper end face of the lower cover plate 53, and an upper conical tooth section 60, which is fixed to the lower end face of the upper cover plate 52. A bevel gear 62 is provided between the lower conical tooth section 61 and the upper conical tooth section 60. The bevel gear 62 is rotatably connected to the inner wall of the straight cylinder 8. Specifically, the shaft end of the bevel gear 62 is installed on the inner side wall of the support frame 51, and the bevel gear 62 meshes with both the lower conical tooth section 61 and the upper conical tooth section 60, so that when the upper cover plate 52 rotates, it can drive the lower cover plate 53 to rotate in the opposite direction through the reversing component.

[0063] like Figures 11 to 14 As shown, the valve body assembly includes a cylindrical cavity 57, which is vertically opened at the intersection of the annular partition 541 and the radial partition 542. Each cylindrical cavity 57 is connected to the surrounding sub-cavities 55. It should be noted that the cylindrical cavity 57 located on the outermost side of the pressure cavity 54 is connected to the intake cavity 88, and the cylindrical cavity 57 located on the innermost side of the pressure cavity 54 is connected to the exhaust cavity.

[0064] Furthermore, a crescent-shaped valve body 69 is rotatably provided inside the cylindrical cavity 57. The outward protrusion of the crescent-shaped valve body 69 can isolate the two sub-cavities 55 located on the same side of the radial partition 542. At this time, the two sub-cavities 55 located on the other side of the radial partition 542 are connected through the inner concave part of the crescent-shaped valve body 69. When the crescent-shaped valve body 69 rotates 180°, the on / off state of the two sets of cavities can be changed.

[0065] Specifically, in combination Figure 14 A first valve 65, a second valve 66, a third valve 67, and a fourth valve 68 are respectively provided around a single cylindrical cavity 57 to connect four sub-cavities 55 around the single cylindrical cavity 57. The first valve 65 and the second valve 66 are both located on the left side of the radial partition 542, and the third valve 67 and the fourth valve 68 are both located on the right side of the radial partition 542. If the crescent-shaped valve body 69 initially blocks the first valve 65 and the second valve 66, then when the crescent-shaped valve body 69 rotates 180°, it blocks the third valve 67 and the fourth valve 68.

[0066] Furthermore, a lower end face gear 75 is fixedly provided on the end face of the crescent-shaped valve body 69, and an upper end face gear 74 is rotatably mounted on the pressure cavity 54 via a shaft 71. The upper end face gear 74 can mesh with the lower end face gear 75, the upper end face gear 74 can rotate with the shaft 71, and the upper end face gear 74 can slide along the axial direction of the shaft 71. For ease of installation, the port of the cylindrical cavity 57 is sealed by an upper cover 79, and the shaft 71 is rotatably connected to the upper cover 79.

[0067] Furthermore, it also includes a spring 72 sleeved on the shaft 71. One end of the spring 72 away from the upper end face gear 74 is fixed by a retaining ring 73, which is fixed to the shaft 71. The other end of the spring 72 is fixed to the upper end face gear 74, and is used to push the upper end face gear 74 to the lower end face gear 75.

[0068] Furthermore, it also includes an upper protrusion 76 fixed on the side of the crescent-shaped valve body 69 away from the drive gear 70. There are two upper protrusions 76 with an included angle of 180°. At the bottom of the cylindrical cavity 57, there are two lower protrusions 77 corresponding to the upper protrusions 76 to limit the rotation of the upper protrusions 76. Specifically, a lower cover 78 is provided on the side of the cylindrical cavity 57 near the upper protrusions 76, and the lower protrusions 77 are fixed on the lower cover 78.

[0069] When the shaft 71 rotates, the crescent-shaped valve body 69 rotates through the meshing of the upper end face gear 74 and the lower end face gear 75. When the crescent-shaped valve body 69 rotates 180°, the lower protrusion 77 will limit the upper protrusion 76, causing the crescent-shaped valve body 69 to stop rotating. At this time, the shaft 71 continues to rotate, and the upper end face gear 74 compresses the spring 72 and moves upward. When the shaft 71 rotates in the opposite direction, the upper end face gear 74 and the lower end face gear 75 re-mesh, and the above process is repeated.

[0070] In addition, a drive gear 70 is fixed at the end of the shaft 71, and the drive gear 70 is located outside the cylindrical cavity 57 to drive the shaft 71 to rotate.

[0071] To facilitate the rotation of the drive gear 70 and thus adjust the state of the valve body assembly, a receiving cavity 63 is provided on both the upper cover plate 52 and the lower cover plate 53. A tooth 64 is fixed in the receiving cavity 63 and meshes with the drive gear 70. The transmission between the tooth 64 and the drive gear 70 is speed-increasing, so that the tooth 64 can drive the drive gear 70 to rotate 180° when rotating at a small angle, thereby changing the state of the valve body assembly. This allows the valve body assembly to respond quickly, prevents backflow of the mixture, and the valve body assembly will not interfere with the rotation of the tooth 64 after changing its state. When the tooth 64 rotates in the opposite direction, it can immediately drive the valve body assembly to change its state.

[0072] It should be noted that the two adjacent valve body assemblies are installed in different directions, so that when the drive gear 70 on one valve body assembly is driven by the upper cover plate 52, the drive gear 70 on the other valve body assembly is driven by the lower cover plate 53, thereby cooperating with the upper piston body 58 and the lower piston body 59 to adjust the on / off state.

[0073] Combination Figure 21 The following describes the manifestation of the above process in a localized area:

[0074] In the diagram, the upper piston 58 rotates clockwise and the lower piston 59 rotates counterclockwise. At this time, the gas storage chamber of the first cavity 551 draws in a mixture from the outer periphery. The exhaust chamber of the first cavity 551 is connected to the gas storage chamber of the second cavity 552. Driven by the upper piston 58, the mixture enters the gas storage chamber of the second cavity 552 from the exhaust chamber of the first cavity 551. Simultaneously, the exhaust chamber of the second cavity 552 is connected to the inner periphery chamber. Driven by the lower piston 59, the mixture is discharged from the exhaust chamber of the second cavity 552. When the upper piston 58 and lower piston 59 rotate... When the maximum movement angle is reached, the volume of the air storage chamber of the first chamber 551 and the second chamber 552 reaches its maximum, and the volume of the exhaust chamber reaches its minimum. Then, the upper piston body 58 and the lower piston body 59 rotate in opposite directions, while driving all valve body components to rotate 180° to change their state, so that the previous exhaust chamber becomes an air storage chamber to re-inhale the mixture, and the air storage chamber becomes an exhaust chamber to expel the inhaled mixture. Then, the above process is repeated, thereby continuously sending the mixture from the air intake chamber 88 to the exhaust chamber, and in this process, the volume of the mixture is reduced to increase the pressure of the mixture.

[0075] like Figure 4 and Figure 18As shown, it should be noted that since there are multiple straight cylinders 8, in order to facilitate the supply of deodorizing liquid to the second atomizers 25 inside the multiple straight cylinders 8, a first ring pipe 10 is provided inside the housing 1. The multiple second atomizers 25 are all connected to the first ring pipe 10, and a first inlet 3 is provided on the housing 1. The first ring pipe 10 is connected to the first inlet 3.

[0076] Combination Figure 5 In order to facilitate the discharge of flue gas from the multiple straight cylinders 8 into the housing 1, a fourth ring pipe 21 is provided inside the housing 1. Preferably, the fourth ring pipe 21 is fixed to the surface of the lower support plate 18 and is surrounded by multiple straight cylinders 8. All the exhaust pipes 26 are connected to the fourth ring pipe 21. A first exhaust outlet 4 is provided on the housing 1. The first exhaust outlet 4 passes through the gap between adjacent straight cylinders 8 and is connected to the fourth ring pipe 21.

[0077] like Figure 8 and Figure 15 As shown, in order to drive the upper cover plate 52 to reciprocate, the first drive assembly mentioned above includes an outer frame 81. The outer frame 81 is fixedly connected to the straight cylinder 8 by a first fixing rod 28. A vertical groove 811 is provided on the inner wall of the outer frame 81. A rotating ring 86 is provided rotatably on the inner side of the outer frame 81. The lower end of the rotating ring 86 is fixedly connected to the upper cover plate 52. An inclined groove 87 is provided on the rotating ring 86.

[0078] Furthermore, a hollow shaft 32 is rotatably provided inside the straight cylinder 8 and located inside the rotating ring 86, and is stably supported by a bracket 31 fixed inside the straight cylinder 8. The hollow shaft 32 is used to input power.

[0079] Furthermore, a fixed sleeve 83 is fixedly connected to the outer circumferential surface of the hollow shaft 32 and is located inside the rotating ring 86. It also includes a guide pin 85 and a wave groove 84. The guide pin 85 passes through the inclined groove 87, and the wave groove 84 is opened on the outer circumferential surface of the fixed sleeve 83. One end of the guide pin 85 is located in the wave groove 84, and the other end is located in the vertical groove 811. A sealing cover 80 is fixedly provided on the upper side of the outer frame 81. The side of the sealing cover 80 near the shaft center is rotatably connected to the hollow shaft 32, thereby protecting the internal structure. When the hollow shaft 32 rotates, it can drive the fixed sleeve 83 to rotate, thereby driving the guide pin 85 to move back and forth in the vertical direction. The guide pin 85 can also push the rotating ring 86 to swing back and forth through the inclined groove 87, thereby realizing the back and forth swing of the upper cover plate 52.

[0080] like Figure 6 , Figure 7 , Figure 16 and Figure 17 As shown, a mixing and diffusion assembly is provided on the lower side of the pressure chamber 54. The mixing and diffusion assembly includes a gradually expanding cone 49. Preferably, the diameter of the gradually expanding cone 49 is less than half of the diameter of the straight cylinder 8, so that a certain space is left between the outer periphery of the gradually expanding cone 49 and the straight cylinder 8, and at the same time, it can also disperse the airflow gathered from the pressure chamber 54.

[0081] Furthermore, it also includes a ring chain 37, which is provided in multiple sets. One end of each set of ring chains 37 is fixed to the outer periphery of the expanding cone 49 and arranged in a circular array. Specifically, a fixing ring 39 is fixedly provided at the outer diameter of the expanding cone 49. One end of each set of ring chains 37 is installed on the fixing ring 39. A flexible rope 38 is also provided. The flexible rope 38 is ring-shaped. The other end of each set of ring chains 37 is fixed to the flexible rope 38 so that there is an angle between the ring chain 37 and the horizontal plane when the ring chain 37 is fully extended. The angle range is 10°-30°, that is, to avoid the angle between the ring chain 37 and the horizontal plane being less than 10° during the rotation. The cooling gas can directly mix with the flue gas through the pores of the ring chain 37. During the rotation of the ring chain 37, turbulent flow is generated through the pores. When the droplets slide on the ring chain 37 due to the influence of centrifugal force, they can also more fully combine with the particles in the flue gas.

[0082] Furthermore, combined Figure 6 In order to facilitate the discharge of liquid in the straight cylinder 8, a drain port 33 is provided at the bottom of the straight cylinder 8. A drain pipe 9 is provided inside the shell 1. The drain pipe 9 is fixed to the inner wall of the shell 1. The drain pipe 9 and the drain port 33 are connected by a second bend pipe 16. The second bend pipe 16 acts as a liquid seal to prevent gas from leaking out of the drain port 33.

[0083] It should be noted that, in combination Figure 3 or Figure 4 Each straight cylinder 8 is equipped with a drain pipe 9. In order to facilitate the discharge of liquid from multiple drain pipes 9 into the housing 1, a second ring pipe 11 is provided inside the housing 1. The bottom end of each drain pipe 9 is connected to the second ring pipe 11. A second outlet 5 is provided on the housing 1, and the second ring pipe 11 is connected to the second outlet 5.

[0084] like Figure 7 and Figure 17 As shown, in order to facilitate the introduction of cooling gas into the straight cylinder 8, a second inlet 6 is provided on the lower side of the housing 1. The second inlet 6 is connected to the interior of the hollow shaft 32. A fixing seat 40 is fixed on the outer circumferential surface of the hollow shaft 32. The air nozzle 41 is installed on the fixing seat 40 and is connected to the interior of the hollow shaft 32.

[0085] It should be noted that, in combination Figure 2 - Figure 4 Since there are multiple hollow shafts 32, in order to facilitate the delivery of cooling gas into the second inlet 6 to the multiple hollow shafts 32, a third ring pipe 12 is provided in the housing 1. The second inlet 6 is connected to the third ring pipe 12, and the bottom ends of the multiple hollow shafts 32 are all connected to the third ring pipe 12.

[0086] like Figure 3 and Figure 16As shown, in order to facilitate the rotation of the hollow shaft 32, a second drive assembly is provided on the lower side of the housing 1. The second drive assembly includes a first synchronous wheel 34, which is fixed on the side near the bottom end of the hollow shaft 32. It should be noted that a mounting plate 50 is provided below the lower support plate 18. The mounting plate 50 and the lower support plate 18 have a certain distance between them. The mounting plate 50 and the lower support plate 18 are fixedly connected. The bottom end of the hollow shaft 32 passes through the lower support plate 18 and is rotatably connected to the mounting plate 50. The first synchronous wheel 34 is located in the space between the mounting plate 50 and the lower support plate 18.

[0087] In addition, a first gear 46 is rotatably disposed on the lower side of the housing 1. The first gear 46 is located in the interval space. Since there are multiple straight cylinders 8, and each straight cylinder 8 has a hollow shaft 32, there are also multiple first gears 46, which are the same number as the number of hollow shafts 32. A second gear 47 is also rotatably disposed in the interval space on the lower side of the housing 1 and meshes with multiple first gears 46.

[0088] Furthermore, a second synchronous pulley 45 is provided, which is coaxially arranged with the second gear 47 and rotates synchronously with the second gear 47. The second synchronous pulley 45 is driven by the first synchronous pulley 34 through the synchronous belt 48. On the lower side of the housing 1, a second motor 14 is also provided. The second motor 14 is mounted on the lower surface of the mounting plate 50. The output end of the second motor 14 passes through the mounting plate 50 and is fixed to the shaft of the first gear 46. Thus, the second motor 14 drives multiple hollow shafts 32 to rotate, thereby driving the mixing diffusion component and the first drive component to rotate.

[0089] Optionally, combined Figure 15 In order to increase the rotational speed of the mixing and diffusion component while avoiding high-speed rotation of the first drive component, a planetary reducer 82 can be provided between the fixed sleeve 83 and the hollow shaft 32. Specifically, the planetary reducer 82 consists of a sun gear 821, planet gears 822 and an external gear ring 823. The sun gear 821 is sleeved on the outer circumferential surface of the hollow shaft 32, and the outer circumferential surface of the external gear ring 823 is fixedly connected to the inner circumferential surface of the fixed sleeve 83.

[0090] like Figure 2 , Figure 3 , Figure 14 and Figure 15As shown, in order to reduce the particulate content in the flue gas to be treated and thus reduce the amount of deodorizing liquid used, a flue gas inlet 2 is fixed at the top of the shell 1. A first atomizer 23 is provided inside the flue gas inlet 2. The first atomizer 23 is used to introduce water mist into the flue gas inlet 2. The atomized particle size of the water is in the range of 80-150μm, thereby capturing larger solid particles with high efficiency. A mixing chamber 7 is connected to the lower end of the flue gas inlet 2. The mixing chamber 7 is used to improve the mixing effect of water mist and flue gas. The mixing chamber 7 is connected to the straight cylinder 8 so that the flue gas can subsequently enter the straight cylinder 8. A liquid collection tank 35 is provided at the bottom of the mixing chamber 7. The liquid collection tank 35 is connected to the drain pipe 9 through a first bend pipe 15.

[0091] Specifically, the aforementioned mixing chamber 7 includes a main cavity 44, the upper end of which is connected to the smoke inlet 2. The lower end of the main cavity 44 has a U-shaped cross-section. It also includes a baffle 43, the bottom end of which is inserted into the lower side of the main cavity 44, so that the lower side of the main cavity 44 forms an air inlet side connected to the smoke inlet 2 and an air outlet side connected to the straight cylinder 8. The air inlet side and the air outlet side are connected at the bottom end of the main cavity 44, so that the flue gas flows from the air inlet side of the main cavity 44 from top to bottom and then flows out of the main cavity 44 from bottom to top. The flue gas generates turbulence during the flow, which improves the mixing effect.

[0092] Furthermore, the reason for setting the liquid collection tank 35 at the bottom of the air inlet side is that smaller droplets can flow from the air inlet side to the air outlet side under the blowing of flue gas and continue to accumulate until the droplets condense to a certain size, overcome the blowing of flue gas and slide down to the liquid collection tank 35, thereby increasing the contact time between the droplets and the flue gas and thus improving the dust removal effect. The liquid collection tank 35 is connected to the drain pipe 9 through the first bend pipe 15 to facilitate the discharge of liquid.

[0093] Optionally, a neck 42 is provided between the smoke inlet 2 and the main cavity 44. The cross-sectional area of ​​the neck 42 is smaller than that of the smoke inlet 2, and the cross-sectional area of ​​the air intake side of the main cavity 44 is larger than that of the smoke inlet 2, thereby increasing the speed at which the flue gas enters the main cavity 44 and increasing the turbulence intensity.

[0094] Optionally, a fan duct 20 is provided between the mixing chamber 7 and the straight cylinder 8, and an upper support plate 17 is also provided inside the shell 1. The fan duct 20 is fixedly connected to the upper support plate 17. The upper end of the fan duct 20 is connected to the exhaust side, and the lower end of the fan duct 20 is connected to the upper side of the straight cylinder 8 through a connecting ventilation duct 19. An axial flow fan 27 is installed inside the fan duct 20. The axial flow fan 27 adopts a vertical downward axial air outlet design. The first motor 13 is installed at the bottom end of the fan duct 20, and the output shaft of the first motor 13 extends into the fan duct 20 and is fixedly connected to the conical shaft of the axial flow fan 27, thereby increasing the flow rate of flue gas entering the straight cylinder 8.

[0095] This invention also provides an enthalpy-reduction flue gas dust removal and deodorization process, applicable to the above-mentioned enthalpy-reduction flue gas dust removal and deodorization device, comprising the following steps:

[0096] Step 1: The flue gas and atomized water are introduced into the mixing chamber 7 and mixed to form the first type of droplets carrying large dust particles. The atomized particle size of the water is 80-150μm.

[0097] Step 2: Discharge the first type of droplets generated during the mixing process and allow the mixed gas flow of flue gas and water into the straight cylinder 8;

[0098] Step 3: After atomizing the deodorizing liquid, introduce it into the straight cylinder 8. The atomized particle size of the deodorizing liquid should be in the range of 10-50μm.

[0099] Step 4: The mixed airflow is introduced into the main chamber from the outer periphery of the straight cylinder 8 and discharged from the inner side of the straight cylinder 8. The mixed airflow is pressurized as it passes through the main chamber.

[0100] Step 5: The mixed airflow is brought into contact with the rotating mixing and diffusion assembly. The angle between the upper surface of the mixing and diffusion assembly and the horizontal plane is in the range of 10°-30°, and the rotation speed is in the range of 300-800 rpm. At the same time, cooling gas is passed through the lower surface of the mixing and diffusion assembly to cool it down, so that the surface of the mixing and diffusion assembly forms a second type of droplet. Centrifugal force is used to make the second type of droplet detach from the surface of the mixing and diffusion assembly and discharge it from the bottom end of the straight cylinder 8.

[0101] Step 6: Discharge the treated purified airflow from the side near the bottom of the straight cylinder 8.

[0102] During use (operation), flue gas and atomized water are introduced into the mixing chamber 7 through the flue gas inlet 2. Large solid particles are captured by the water mist, and the agglomerated liquid is collected and discharged through the liquid collection tank 35. Then, the flue gas continues to be introduced into the straight cylinder 8 and mixed with the atomized deodorizing liquid. After being pressurized and mixed by the pressure chamber 54, the mixture converges and impacts the mixing and diffusion component below. The hollow shaft 32 drives the mixing and diffusion component to rotate, forming turbulence and throwing the agglomerated droplets towards the inner wall of the straight cylinder 8. The droplets move downward and enter the next set of pressure chambers 54 and mixing and diffusion components together with the flue gas until the bottom of the straight cylinder 8. Then, the liquid is discharged through the drain port 33, and the flue gas is discharged through the exhaust pipe 26.
