Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, and in particular to an adjustable cyclone desulfurization tower. Background Technology

[0002] Flue gas desulfurization technology mainly includes three methods: wet desulfurization, semi-dry desulfurization, and dry desulfurization. Among them, wet desulfurization is the most widely used method. The core principle of wet desulfurization is to utilize the alkaline absorbent to react with sulfur dioxide (SO2) in the flue gas to generate sulfate products, thereby achieving desulfurization. Wet desulfurization towers designed based on this mechanism are widely used in the flue gas treatment of various types of power plants.

[0003] Traditional desulfurization towers use internal and external pressure differences to cause flue gas to rise and contact with the slurry for absorption. However, relying solely on pressure differences results in insufficient residence time for the flue gas and inadequate contact area with the slurry, leading to insufficient desulfurization efficiency. Simultaneously, the internal structure of the desulfurization tower creates resistance, which the flue gas must overcome to flow. Current desulfurization towers employ multi-layer spraying or the addition of support plates to improve efficiency, but these solutions all increase internal resistance. Increased resistance leads to uneven flue gas distribution, higher operating costs, and ultimately, insufficient desulfurization efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an adjustable cyclone desulfurization tower to overcome the problem of insufficient desulfurization efficiency of existing desulfurization towers.

[0013] In one embodiment, the arc-shaped plate is mounted on the spacer plate by an adjusting screw. The adjusting screw is connected to a drive motor, which drives the adjusting screw to rotate, causing the arc-shaped plate to rotate around the adjusting screw as the rotation axis. This causes the arc-shaped plate to rotate as the relative angle of the first swirl blade and the second swirl blade changes.

[0014] In one embodiment, the adjusting screw extends into the spacer plate and extends outward from the drive end of the drive motor corresponding to the receiving through hole to form a transmission cavity. The drive end of the drive motor is provided with a rotating gear disk, which is disposed in the transmission cavity and is connected to the adjusting screw in a transmission connection.

The transmission cavity is located between the straight cylindrical section and the diffuser section. The second swirl blade is disposed inside the straight cylindrical section, and the first swirl blade is disposed inside the diffuser section. The diameter of the straight cylindrical section is equal to the diameter of the second swirl blade, and the diameter at the maximum point of the diffuser section is equal to the diameter of the first swirl blade.

[0017] In one embodiment, the through-hole further includes a contraction section located below the straight section, the diameter of which gradually decreases from the bottom of the partition plate to the straight section.

[0018] In one embodiment, the spacer plate is provided with tapered flow holes.

[0019] In one embodiment, an inclined perforated plate is provided on the top of the slurry layer, and the inclined perforated plate gradually slopes upward from the side near the air inlet to the side away from the air inlet.

[0020] The beneficial effects of this utility model are as follows: The adjustable cyclone desulfurization tower provided by this utility model enables the flue gas to form a cyclone through a multi-stage cyclone blade assembly, and the formed cyclone is longitudinally strengthened by an arc-shaped plate, allowing the cyclone to overcome the internal resistance of the desulfurization tower and quickly reach the spray layer to react with the slurry, effectively improving the desulfurization efficiency and effect. At the same time, the adjustable multi-stage cyclone blades allow operators to adjust the cyclone speed and cyclone angle range of the flue gas as needed, thereby controlling the residence time and contact area of ​​the flue gas in the adjustable cyclone desulfurization tower. This allows the adjustable cyclone desulfurization tower to adapt to flue gas of different concentrations and feed rates, exhibiting good adaptability. Attached Figure Description

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] Please refer to Figures 1 to 4 An adjustable cyclone desulfurization tower includes a tower body 1, and the tower body 1 is provided with a slurry layer 5, a cyclone generating layer 2, a spray layer 3 and a demisting layer 4 from bottom to top.

[0031] The tower body 1 has an absorption chamber 11 inside, an air inlet 12 on the side wall, and an air outlet 13 on the top.

[0032] A swirl generation layer 2 is disposed above the air inlet 12 to create a swirl of flue gas delivered through the air inlet 12. The swirl generation layer 2 includes a spacer plate 21, a multi-stage swirl blade assembly 22, and an arc-shaped plate 23. The spacer plate 21 has a receiving through-hole 211, the multi-stage swirl blade assembly 22 is disposed within the receiving through-hole 211, and the arc-shaped plate 23 surrounds the receiving through-hole 211 and is disposed above the spacer plate 21. The swirl blades of different stages of the multi-stage swirl blade assembly 22 can rotate relative to each other. The flue gas entering through the air inlet 12 is dispersed by the multi-stage swirl blade assembly 22 to generate a swirl, which is then enhanced by the arc-shaped plate 23 and rises. Specifically, the multi-stage swirl blade assembly 22 has at least two stages of swirl blades. The operator can control the relative rotation of the two stages of swirl blades within the receiving through-hole 211, thereby controlling the path formed by the flue gas after being guided by the multi-stage swirl blade assembly 22, and thus controlling the velocity, angle, and swirl distribution of the formed swirl. Meanwhile, multiple arc-shaped plates 23 are arranged around each receiving through-hole 211 above the partition plate 21, and the arc-shaped plates 23 are distributed vertically. Preferably, the arc-shaped plates 23 are concentrically arranged with the receiving through-holes 211, so that the swirling flow formed by the flue gas after passing through the multi-stage swirl blade assembly 22 can flow along the inner surface of the arc-shaped plates 23, causing the swirling flow to converge upward, enhancing the longitudinal lift, ensuring the stability of the vortex, and enabling the swirling flow to overcome the overall resistance inside the desulfurization tower, and fully contacting the slurry in the spray layer 3, thereby improving the desulfurization efficiency. More preferably, guide plates are provided at intervals on the inner surface of the arc-shaped plates 23 to further ensure the stability of the swirling flow, ultimately improving the desulfurization effect.

[0033] Specifically, the spacer plate 21 has through holes 211 distributed on it. The through holes 211 can be located at the center of the spacer plate 21 and / or arranged around the center of the spacer plate 21. Those skilled in the art can set different numbers of through holes depending on the size of the spacer plate 21. Preferably, the spacer plate 21 is symmetrical after the through holes 211 are set, thereby ensuring that the swirl distribution is balanced after the multi-stage swirl blade assembly 22 is installed, and avoiding mutual interference between the swirls that would affect the desulfurization effect.

[0034] The spray layer 3 is located above the swirl generation layer, and the slurry layer 5 is transported to the spray layer 3 through the circulation pipeline 51. The demisting layer 4 is located below the air outlet 13, and sprays clean water and demistates the flue gas after spraying the slurry to ensure that the final output gas meets the emission standards.

[0035] Understandably, the adjustable cyclone desulfurization tower provided by this utility model enables flue gas to form a cyclone through a multi-stage cyclone blade assembly 22, and the arc-shaped plate 23 longitudinally strengthens the formed cyclone, allowing it to overcome the internal resistance of the desulfurization tower and quickly reach the spray layer 3 to react with the slurry, effectively improving desulfurization efficiency and effect. Simultaneously, the adjustable multi-stage cyclone blades allow operators to adjust the cyclone speed and cyclone angle range of the flue gas as needed, thereby controlling the residence time and contact area of ​​the flue gas within the adjustable cyclone desulfurization tower. This allows the adjustable cyclone desulfurization tower to adapt to flue gas of different concentrations and feed rates, exhibiting good adaptability.

[0036] In one embodiment, the multi-stage swirl blade assembly 22 includes a first swirl blade 221, a second swirl blade 222, and a drive motor 223. The drive motor 223 is located at the bottom of the first swirl blade 221, and the drive end of the drive motor 223 is connected to the axis of the second swirl blade 222. The drive motor 223 drives the second swirl blade 222 to rotate relative to the first swirl blade 221. This configuration allows the operator to actively adjust the relative angle between the first swirl blade 221 and the second swirl blade 222 as needed, thereby controlling the overall opening and closing degree of the multi-stage swirl blades and ultimately adjusting the flow velocity and distribution range of the formed swirl, effectively improving the adaptability and operability of the adjustable swirl desulfurization tower.

[0037] In one embodiment, a detection sensor is provided on the arc-shaped plate 23, and the detection sensor is electrically connected to the drive motor 223. The detection sensor is used to detect the flow rate and / or flow rate of the vortex passing through the arc-shaped plate 23 in real time. When the flow rate and / or flow rate reach the set value, the signal is transmitted to the drive motor 223 to control the drive motor 223 to operate and adjust the overall opening and closing degree of the multi-stage vortex blades to ensure that the flow rate and flow rate of the vortex are within the control range, thereby ensuring the residence time of the vortex in the adjustable vortex desulfurization tower, improving the desulfurization effect and operability.

[0038] In one embodiment, the arc-shaped plate 23 is mounted on the spacer plate 21 via an adjusting screw 231. The adjusting screw 231 is connected to a drive motor 223, which drives the adjusting screw 231 to rotate, causing the arc-shaped plate 23 to rotate around the adjusting screw 231 as its axis of rotation. This causes the arc-shaped plate 23 to rotate as the relative angles of the first swirling blade 221 and the second swirling blade change. In other words, the arc-shaped plate 23 rotates according to the opening and closing degree of the multi-stage swirling blades, allowing the swirling currents to converge or disperse, and affecting the distance between different swirling currents. Adjusting a single swirling current affects the overall distribution of the swirling currents, further enhancing the stability of the formed swirling currents. Specifically, those skilled in the art can adjust the angle of the arc-shaped plate 23 corresponding to the relative angles of different first swirling blades 221 and second swirling blades as needed, without specific limitations. Specifically, the transmission part of the drive motor 223 can use a gear set or a screw and gear to drive the adjusting screw 231. The transmission part can be set inside the partition plate 21 to avoid the transmission part from interfering with the flow of flue gas and to prevent the flue gas from corroding the transmission part.

[0039] Preferably, the adjusting screw 231 extends into the partition plate 21, and the through hole 211 extends outward from the drive end of the drive motor 223 to form a transmission cavity. The drive end of the drive motor 223 is provided with a rotating gear 224, which is disposed in the transmission cavity and is connected to the adjusting screw 231 in a transmission connection. That is, the through hole 211 extends laterally out of the transmission cavity, and the adjusting screw 231 extends into the transmission cavity through the opening and is connected to the rotating gear 224 in a transmission connection. Specifically, a transmission gear can be provided at the bottom of the adjusting screw 231 or a worm gear can be provided corresponding to the rotating gear 224, etc., for transmission, without specific limitations. This arrangement accommodates the entire transmission part of the arc plate 23 within the transmission cavity, which can prevent the transmission part of the adjusting screw 231 from being corroded by flue gas and improve the overall service life.

[0040] In one embodiment, the rotating gear disk 224 includes an inner ring 2241 and an outer ring 2242. A vertical connecting wall 2243 is provided between the inner ring 2241 and the outer ring 2242. The inner ring 2241, the outer ring 2242, and the connecting part together form a ventilation perforation 2244. The inner ring 2241 is connected to the drive end of the drive motor 223, and the outer ring 2242 is connected to the adjusting screw 231. This arrangement can effectively prevent the rotating gear disk 224 from interfering with the flow of flue gas and ensure the stability of the formed vortex.

[0041] Preferably, the inner surface of the inner ring 2241 is provided with internal teeth, and the outer surface of the outer ring 2242 is provided with external teeth. The internal teeth are connected to the drive end of the drive motor 223, and the external teeth are connected to multiple adjusting screws 231. This ensures that the arc plate 23 corresponding to each group of multi-stage swirl blades 22 rotates synchronously, ensuring swirl enhancement and control effects.

[0042] In one embodiment, the diameter of the second swirl blade 222 is smaller than the diameter of the first swirl blade 221. The receiving through hole 211 includes a straight section 2112 and a diffuser section 2111. The straight section 2112 is disposed below the diffuser section 2111, and the transmission cavity is located between the straight section 2112 and the diffuser section 2111. The second swirl blade 222 is disposed within the straight section 2112, and the first swirl blade 221 is disposed within the diffuser. The diameter of the straight section 2112 is equal to the diameter of the second swirl blade 222, and the diameter at the maximum point of the diffuser section 2111 is equal to the diameter of the first swirl blade. That is, the flue gas first passes through the smaller-diameter second swirl blade 222, and then through the larger-diameter first swirl blade 221. This causes the flue gas to disperse circumferentially, expanding the distribution range of the formed swirl and allowing the swirl to expand to the inner surface of the arc-shaped plate 23, thereby enhancing the swirl.

[0043] Preferably, the receiving through-hole 211 further includes a contraction section 2113, which is located below the straight section 2112. The diameter of the contraction section 2113 gradually decreases from the bottom of the partition plate 21 to the straight section 2112. This arrangement makes the receiving through-hole 211 form a Venturi structure, which can increase the flow rate of the flue gas and thus make the formed vortex more stable.

[0044] Preferably, the spacer plate 21 is provided with a conical flow hole 24. The conical flow hole 24 allows the adsorbed slurry to drip into the slurry layer 5, forming a slurry circulation and improving the utilization rate of the slurry.

[0045] In one embodiment, an inclined perforated plate 52 is provided at the top of the slurry layer 5. The inclined perforated plate 52 gradually slopes upward from the side near the air inlet 12 to the side away from the air inlet 12. The inclined perforated plate 52 is provided with an array of drip holes, which allow the settled slurry droplets to fall back into the slurry layer 5. The inclined arrangement allows the inclined perforated plate 52 to guide the airflow, enabling the flue gas to be guided to the spacer plate 21 as quickly as possible.

[0046] Preferably, a guide arc plate 521 is provided above the inclined orifice plate 52. The guide arc plate 521 guides the flue gas to the multi-stage swirl blade assembly 22, thereby improving the desulfurization efficiency.

[0047] Please refer to Figures 1 to 4 Embodiment 1 of this utility model is: an adjustable cyclone desulfurization tower, comprising:

[0048] The tower body 1 has an internal absorption chamber 11, an air inlet 12 on the side wall, and an air outlet 13 on the top.

[0049] The swirl generation layer 2, located above the air inlet 12, includes a partition plate 21, a multi-stage swirl blade assembly 22, and an arc-shaped plate 23. The partition plate 21 has five receiving through holes 211 arranged in a cross shape. The multi-stage swirl blade assembly 22 is located within the receiving through holes 211, and three sets of arc-shaped plates 23 are arranged around each receiving through hole 211 above the partition plate 21. The multi-stage swirl blade assembly 22 includes a first swirl blade 221, a second swirl blade 222, and a drive motor 223. The drive motor 223 is located at the bottom of the first swirl blade 221, and its drive end is connected to the axis of the second swirl blade 222, driving the second swirl blade 222 to rotate relative to the first swirl blade 221. A detection sensor is located in the middle of the arc-shaped plate 23, and the detection sensor is electrically connected to the drive motor 223. The arc-shaped plate 23 is mounted on the partition plate 21 via an adjusting screw 231. The adjusting screw 231 is connected to the drive motor 223, which drives the adjusting screw 231 to rotate, causing the arc-shaped plate 23 to rotate around the adjusting screw 231 as its axis of rotation. This causes the arc-shaped plate 23 to rotate as the relative angle of the first swirl vane 221 and the second swirl vane changes. The adjusting screw 231 extends into the partition plate 21, forming a transmission cavity from the drive end of the drive motor 223 corresponding to the receiving through hole 211. The drive end of the drive motor 223 is provided with a rotating gear disk 224, which is located within the transmission cavity and is connected to the adjusting screw 231. The rotating gear disk 224 includes an inner ring 2241 and an outer ring 2242. A vertical connecting wall 2243 is provided between the inner ring 2241 and the outer ring 2242. The inner ring 2241, the outer ring 2242 and the connecting part together form a ventilated hollow 2244. The inner ring 2241 is connected to the drive end of the drive motor 223, and the outer ring 2242 is connected to the adjusting screw 231.

[0050] Spray layer 3 is positioned above the swirl generation layer;

[0051] Demisting layer 4 is located below air outlet 13;

[0052] The slurry layer 5 is located at the bottom of the tower body 1, and the slurry is transported to the spray layer 3 through the circulation pipeline 51.

[0053] In this embodiment, the diameter of the second swirl blade 222 is smaller than the diameter of the first swirl blade 221. The receiving through hole 211 includes a straight cylindrical section 2112 and a diffuser section 2111. The straight cylindrical section 2112 is disposed below the diffuser section 2111. The transmission cavity is located between the straight cylindrical section 2112 and the diffuser section 2111. The second swirl blade 222 is disposed within the straight cylindrical section 2112, and the first swirl blade 221 is disposed within the diffuser. The diameter of the straight cylindrical section 2112 is equal to the diameter of the second swirl blade 222, and the diameter at the maximum point of the diffuser section 2111 is equal to the diameter of the first swirl blade. The receiving through hole 211 also includes a contraction section 2113, which is disposed below the straight cylindrical section 2112. The diameter of the contraction section 2113 gradually decreases from the bottom of the partition plate 21 to the straight cylindrical section 2112.

[0054] The working principle of this utility model is as follows: Before use, the operator adjusts the relative angle between the first swirl blade 221 and the second swirl blade 222, and adjusts the direction of the arc plate 23. Then, the flue gas is introduced into the air inlet 12. After the flue gas flows along the second swirl blade 222 and the first swirl blade 221, it forms a swirling flow. The swirling flow rises and is further guided and strengthened by the arc plate 23. Then, the swirling flow enters the spray layer 3 and fully contacts the slurry. After passing through the demisting layer 4, it is discharged from the air outlet 13. The detection sensor on the arc plate 23 detects the flow rate and volume of the swirling flow. When it is too small or too large, the relative angle between the first swirl blade 221 and the second swirl blade 222 is adjusted to make the overall opening and closing angle smaller or larger, thereby increasing or decreasing the flow rate. At the same time, the arc plate 23 rotates to separate or bring the swirling flow closer together. The spacing is adjusted to control the influence range of a single swirling flow, so that the swirling flow can contact the slurry in the spray layer 3 as much as possible.

[0055] Although this document uses terms such as tower body, absorption cavity, air inlet, air outlet, swirl generation layer, partition plate, receiving through hole, diffuser section, straight section, contraction section, and multi-stage swirl blade assembly frequently, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
