[0017] The technical solution of the present invention has the following significant beneficial effects:

[0018] 1. The present invention transports the flue gas to be treated into the tower body from the flue gas inlet, and uses the swirl blades to make the flue gas passing through the dehydration channel rotate at high speed, and then uses the centrifugal force of the high-speed rotation of the flue gas to separate the mechanical water and particulate matter in the flue gas. Under the action of centrifugal force, the mechanical water and particulate matter will collide with the inner wall of the tower body, and the mechanical water entrains the particulate matter and flows along the inner wall of the tower body to the drainage structure for discharge, thereby playing the role of dehydration and dust removal; the flue gas after dehydration and dust removal continues to rise into the discharge channel, and is finally ignited by the discharge ignition device and discharged into the atmosphere to remove CO in the flue gas; the dehydration and dust removal tower of the present invention can integrate the dehydration and dust removal functions and the ignition and dispersion functions, not only removes the mechanical water and particulate matter in the flue gas, but also removes the CO in the flue gas, and can make the flue gas meet the ultra-low emission requirements. The present invention has the characteristics of high integration, can greatly reduce investment costs and floor space, and its structure is reliable and easy to use.

[0019] 2. The water retaining guide plate can block the condensed water falling from the discharge channel and divert it to prevent the condensed water from falling directly and being blown away by the flue gas again, thereby affecting the dehydration effect; the flue gas deflection area formed by the deflection cylinder and the water retaining guide plate causes the flue gas to form a downward deflection. During the deflection process, the mechanical water in the flue gas can be drained by colliding with the water retaining guide plate and / or the deflection cylinder.

[0020] 3. The separated condensed water and mechanical water can be collected by the first water collecting trough and the second water collecting trough, and the water is directly diverted to the discharge structure through the first guide pipe and the second guide pipe for discharge, further preventing the water from being blown away by the flue gas during the falling process, so as to achieve better flue gas dehydration effect.

[0021] 4. Setting up the lower guide cone can play the role of combing the airflow, so that the flue gas can pass through the dehydration channel between the cyclone tube and the inner wall of the tower body evenly; setting up the upper guide cone can play the role of maintaining the rotation of the airflow and enhancing the stability of the flue gas movement; by setting swirl blades with a certain angle on the cyclone tube, the flue gas can be accelerated and rotated, thereby generating sufficient centrifugal force for dehydration and dust removal.

[0022] 5. A flue gas channel and a water flow channel can be formed through the separation cylinder. The flue gas enters the dehydration channel along the flue gas channel for centrifugal dehydration and dust removal operations. The centrifuged water will be thrown onto the side wall of the tower body and then flow into the water flow channel and enter the second water collection tank along the water flow channel. The separation cylinder can separate the water and flue gas, reduce the contact between water and flue gas, and prevent water from being blown away by the flue gas, thereby improving the dehydration and dust removal effect.

[0023] 6. The flue gas conveying pipe is arranged along the tangent direction of the side wall of the tower body. This arrangement enables the flue gas to obtain an initial rotation speed when it is input into the tower body, and then a stronger centrifugal force can be generated when the flue gas passes through the swirl blades, making the centrifugal dehydration and dust removal effect better; the flue gas conveying pipe is arranged to be inclined toward the tower body, which can make the flue gas first downward and then upward, and the larger water and particulate matter in the flue gas automatically fall under the action of gravity, which plays a role in preliminary separation.

[0024] 7. The tower body adopts the first tower section and the second tower section with different diameters. Increasing the diameter of the second tower section while ensuring that the first tower section meets the dispersion requirements can increase the wind resistance and stability of the tower body.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] The present invention provides a dehydration dust removal tower, such as Figure 1 and Figure 2 As shown, the dehydration dust removal and dispersion tower includes a tower body 1, in which a dispersion channel 14, a cyclone dehydration device 2, a flue gas inlet 3 and a drainage structure 8 are arranged from top to bottom. A dispersion ignition device 9 is installed at the outlet of the dispersion channel 14, and a dehydration channel 25 is provided between the cyclone dehydration device 2 and the inner wall of the tower body 1, and a plurality of cyclone blades 21 are provided in the dehydration channel 25.

[0044] Specifically, tower body 1 comprises, from top to bottom, a first tower section 11 and a second tower section 12. The diameter of first tower section 11 is smaller than that of second tower section 12. First and second tower sections 11, 12 are connected by a reducing section 13. A discharge passage 14 is provided in first tower section 11. The outlet of discharge passage 14 communicates with the atmosphere via a discharge ignition device 9, and the inlet of discharge passage 14 communicates with second tower section 12. A cyclone dehydration device 2, a flue gas inlet 3, and a drainage structure 8 are provided in second tower section 12, sequentially from top to bottom. The diameters of first and second tower sections 11, 12 differ. Enlarging the diameter of second tower section 12 while ensuring that first tower section 11 meets discharge requirements can enhance the wind resistance and stability of tower body 1.

[0045] Specifically, such as Figure 4 As shown, the flue gas inlet 3 is provided on the side wall of the tower body 1. A flue gas conveying pipe 31 is connected to the flue gas inlet 3. The flue gas conveying pipe 31 is arranged on the tower body 1 along a tangential direction of the side wall of the tower body 1. The flue gas is conveyed into the tower body 1 in a first rotation direction A through the flue gas conveying pipe 31. A plurality of swirl blades 21 are arranged in an annular arrangement along the first rotation direction A. The flue gas conveying pipe 31 is arranged along the tangential direction of the side wall of the tower body 1. This arrangement enables the flue gas to obtain an initial rotational speed when it is input into the tower body 1. At the same time, the plurality of swirl blades 21 are arranged clockwise along the first rotation direction A. This generates a stronger centrifugal force when the flue gas passes through the swirl blades 21, resulting in better centrifugal dehydration and dust removal effects.

[0046] Furthermore, the smoke conveying pipe 31 is tilted toward the tower body 1. Specifically, the end of the smoke conveying pipe 31 connected to the tower body 1 is tilted downward. When the smoke conveying pipe 31 is tilted toward the tower body 1, the smoke first descends along the tilted direction of the smoke conveying pipe 31 after being discharged from the smoke conveying pipe 31, and then rises again. This allows larger water and particulate matter in the smoke to automatically fall under the action of gravity, thereby achieving a preliminary separation effect.

[0047] In this embodiment, if Figure 5 As shown, the cyclone dehydration device 2 is fixed to the tower body 1 via a bracket 26. The cyclone dehydration device 2 includes an upper guide cone 22, a lower guide cone 23, and a cyclone barrel 24 connected between the upper and lower guide cones 22 and 23. The cyclone barrel 24 is spaced apart from the inner wall of the tower body 1 to form a dehydration channel 25. A plurality of cyclone blades 21 are arranged and connected to the outer wall of the cyclone barrel 24. The cyclone blades 21 are fixed to the cyclone barrel 24 at a specific angle and number. The number and angle of the cyclone blades 21 are determined according to actual usage requirements and are not limited here.

[0048] Specifically, multiple brackets 26 are provided, arranged in a circular pattern. Each bracket 26 includes a support 261 and a support rod 262. The support 261 is connected to the inner wall of the tower body 1. One end of the support rod 262 is connected to the corresponding support 261, and the other end of the support rod 262 is connected to the lower guide cone 23. The number of brackets 26 provided depends on actual usage needs and is not limited here. Of course, the brackets 26 can also be replaced by other structures that provide the same support function.

[0049] In this embodiment, a water retaining plate 4 is provided between the discharge channel 14 and the cyclone dehydration device 2. The water retaining plate 4 is disposed below the discharge channel 14 and has a flue gas through hole 41 in communication with the discharge channel 14. The water retaining plate 4 is inclined downward from the flue gas through hole 41 toward the inner wall of the tower body 1. The water retaining plate 4 can block and guide the condensed water falling from the discharge channel 14, preventing the condensed water from falling directly and being blown away again by the flue gas, thereby affecting the dehydration effect.

[0050] Furthermore, a deflector 42 is connected below the smoke through hole 41, and a smoke deflection area 43 is formed between the deflector 42 and the water deflector 4. The smoke deflection area 43 formed by the deflector 42 and the water deflector 4 causes the smoke to form a downward deflection. During the deflection process, mechanical water rising with the smoke can collide with the water deflector 4 and / or the deflector 42 to be discharged.

[0051] In this embodiment, if Figure 3 As shown, a water collecting structure 5 is provided in the tower body 1, and the water collecting structure 5 includes a first water collecting trough 51 and a second water collecting trough 52. The first water collecting trough 51 is connected between the water retaining guide plate 4 and the inner wall of the tower body 1, and the second water collecting trough 52 is arranged below the dehydration channel 25. A guide pipe structure 6 is provided between the first water collecting trough 51, the second water collecting trough 52 and the drainage structure 8.

[0052] Specifically, the drainage pipe structure 6 includes three first drainage pipes 61 and three second drainage pipes 62. One end of the first drainage pipe 61 is connected to the first water collecting trough 51, and the other end of the first drainage pipe 61 is arranged above the second water collecting trough 52. One end of the second drainage pipe 62 is connected to the second water collecting trough 52, and the other end of the second drainage pipe 62 is arranged above the drainage structure 8. The three first drainage pipes 61 and the three second drainage pipes 62 are arranged in an annular arrangement, which can ensure more uniform drainage.

[0053] During use, the water in the first water collecting trough 51 is transported to the second water collecting trough 52 through the first guide pipe 61, and the water separated by the dehydration channel 25 also flows into the second water collecting trough 52 along the side wall of the tower body 1. Therefore, the water flow rate in the second water collecting trough 52 is greater than the water flow rate in the first water collecting trough 51. In order to quickly discharge the water in the second water collecting trough 52 into the drainage structure 8, the diameter of the second guide pipe 62 is further made larger than the diameter of the first guide pipe 61.

[0054] In this embodiment, if Figure 3 and Figure 5 As shown, a separation tube 7 is provided between the lower guide cone 23 and the side wall of the tower body 1. The separation tube 7 is located above the second water collecting trough 52. The separation tube 7 is fixed between the cyclone tube 24 and the second water collecting trough 52. The top end of the separation tube 7 is connected to the cyclone tube 24 through a plurality of connecting clips 73. The plurality of connecting clips 73 are arranged in a ring-shaped interval. The bottom end of the separation tube 7 is connected to the second water collecting trough 52. The separation tube 7 and the side wall of the tower body 1 are spaced apart to form a water flow channel 71. The bottom outlet of the water flow channel 71 is arranged above the second water collecting trough 52. The separation tube 7 and the lower guide cone 23 are spaced apart to form a flue gas channel 72. The top outlet of the flue gas channel 72 is connected to the dehydration channel 25. A flue gas channel 72 and a water flow channel 71 can be formed through the separation tube 7. The flue gas enters the dehydration channel 25 along the flue gas channel 72 for centrifugal dehydration and dust removal operations. The centrifuged water will be thrown onto the side wall of the tower body 1 and then flow into the second water collecting tank 52 along the water flow channel 71. The flue gas and the centrifuged water can be separated by the separation tube 7, reducing the contact between water and flue gas, preventing water from being blown away and carried away by the flue gas, and improving the dehydration and dust removal effect.

[0055] In this embodiment, if Figure 1 As shown, the drainage structure 8 includes a drainage port 81 provided on the tower body 1 and a drainage guide plate 82 fixed in the tower body 1 . The drainage guide plate 82 is tilted toward the drainage port 81 .

[0056] When the present invention is used, the flue gas to be treated is transported into the tower body 1 from the flue gas inlet 3, and the flue gas passing through the dehydration channel 25 is rotated at high speed by the swirl blades 21, and then the mechanical water and particulate matter in the flue gas are separated by the centrifugal force of the high-speed rotation of the flue gas. Under the action of the centrifugal force, the mechanical water and particulate matter will collide with the inner wall of the tower body 1, and the mechanical water entrained with the particulate matter will flow along the inner wall of the tower body 1 through the water flow channel 71 into the second water collecting tank 52, and then the water in the second water collecting tank 52 is transported to the drainage guide plate 82 through the second guide pipe 62, and then discharged through the drain port 81; the flue gas after centrifugal dehydration and dust removal continues to rise into the emission channel 14, and is finally ignited by the emission ignition device 9 and discharged into the atmosphere to remove CO in the flue gas. After the above treatment, the particulate matter content in the flue gas is ≤10mg / Nm 3During use, some water vapor will condense in the discharge channel 14 and flow down along the discharge channel 14 , and most of the condensed water that flows down will be blocked by the water retaining guide plate 4 and directed to the first water collecting tank 51 , and then the water in the first water collecting tank 51 will be transported to the second water collecting tank 52 through the first guide pipe 61 .

[0057] The dehydration, dust removal and dispersion tower of the present invention has the beneficial effect of integrating the dehydration, dust removal and ignition dispersion functions. It can not only quickly remove particulate matter in mechanical water but also remove CO in flue gas, so that the flue gas can meet ultra-low emission requirements. It has the characteristics of high integration, can greatly reduce investment costs and floor space, and its structure is reliable and easy to use.
