Description

Technical Field

[0001] This invention belongs to the field of flue gas desulfurization technology, and in particular relates to a device and method for dynamic diversion and turbulence enhancement of flue gas in wet magnesium desulfurization towers. Background Technology

[0002] Wet magnesium oxide desulfurization is one of the mainstream processes for flue gas purification in coal-fired power plants and industrial boilers. Using magnesium oxide as the desulfurizing agent, it boasts advantages such as high desulfurization efficiency and low operating costs, and is widely used in integrated flue gas desulfurization tower structures. In this structure, flue gas enters from the bottom of the tower and flows vertically upwards, reacting counter-currently with the desulfurization alkaline solution sprayed from top to bottom. However, existing technologies generally have several drawbacks. Traditional desulfurization towers are mostly cylindrical structures, with flue gas flowing vertically upwards in a co-current manner. This single flow pattern results in short contact time between the flue gas and the alkaline solution, insufficient mixing, and a tendency for airflow deviation—higher velocity in the center and slower velocity at the sides—severely restricting gas-liquid mass transfer efficiency. Furthermore, the actual operating load of industrial boilers fluctuates frequently and significantly, but traditional towers lack corresponding adaptive adjustment mechanisms. Under low-load conditions, uneven airflow distribution easily occurs, while under high-load conditions, insufficient contact time affects the desulfurization effect. To meet emission requirements, it is usually necessary to increase the spray density or the tower height, which leads to increased energy consumption and construction costs. Although there are solutions in the existing technology that involve adding fixed guide vanes or static turbulence devices, they cannot dynamically adjust the turbulence intensity according to the real-time flue gas load, making it difficult to achieve efficient, stable and economical operation across the entire load range. In particular, they are difficult to meet the stringent requirements of the increasingly stringent ultra-low emission standards for the adaptability of desulfurization systems to varying operating conditions. Summary of the Invention

[0003] In view of this, the present invention aims to propose a device and method for dynamic flue gas diversion and turbulence enhancement in wet magnesium desulfurization towers, so as to solve the problem of unstable desulfurization efficiency caused by uneven gas-liquid mixing and insufficient contact reaction time in traditional desulfurization towers under varying operating conditions.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a flue gas dynamic steering and turbulence enhancement device for a wet magnesium desulfurization tower, comprising a tower body, a spray assembly, a blade support, a tower inlet, a sealing assembly, a rotating shaft, steering blades, and a control system; the upper part of the tower body is provided with the spray assembly, and the lower part is provided with the tower inlet; multiple steering blades are arranged circumferentially along the inner wall of the tower body between the tower inlet and the spray assembly, each steering blade is fixedly connected to a rotating shaft, and the rotating shaft is rotatably installed in the tower body; each rotating shaft is connected to a drive assembly; an angle sensor is installed on the rotating shaft; the control system is communicatively connected to the drive assembly and the angle sensor, and receives flue gas flow signals; the control system controls the drive assembly to drive the rotating shaft to rotate according to the flue gas flow signals, thereby adjusting the opening of the steering blades, the cross-section of the steering blades is airfoil-shaped, and the edges of the steering blades are provided with serrated structures.

[0005] Furthermore, the drive mechanism includes a servo stepper motor and a reducer. The servo stepper motor is connected to the rotating shaft through the reducer, and an angle sensor is also provided on the rotating shaft.

[0006] Furthermore, the drive mechanism also includes a reducer mounting base, which is disposed on the outer wall of the tower body, and the servo stepper motor and the reducer are disposed on the reducer mounting base.

[0007] Furthermore, the flue gas dynamic steering and turbulence enhancement device of the wet magnesium desulfurization tower also includes a wind pressure measuring device, which is installed through the wall of the tower body and located above the steering blades.

[0008] Furthermore, the flue gas dynamic steering and turbulence enhancement device of the wet magnesium desulfurization tower also includes a compressed air backflushing component, which is connected to a wind pressure measuring device.

[0009] Furthermore, the flue gas dynamic steering and turbulence enhancement device of the wet magnesium desulfurization tower also includes a backwashing component, which is located above the spraying component.

[0010] Furthermore, the flue gas dynamic diversion and turbulence enhancement device of the wet magnesium desulfurization tower also includes a platform, which is set outside the tower body.

[0011] Furthermore, the flue gas dynamic steering and turbulence enhancement device of the wet magnesium desulfurization tower also includes a blade support and a bushing. The blade support is located inside the tower body and between the tower air inlet and the spray assembly. The bushing is located on the blade support. The end of the rotating shaft is rotatably installed in the bushing. The blade support is a regular 12-sided polygon.

[0012] Furthermore, the flue gas dynamic steering and turbulence enhancement device of the wet magnesium desulfurization tower also includes a sealing component. The rotating shaft is installed through the wall of the tower body, and the sealing component is installed at the part where the rotating shaft exits and is connected to the drive component.

[0013] A method for dynamic flue gas diversion and turbulence enhancement, applied to a flue gas dynamic diversion and turbulence enhancement device in a wet magnesium desulfurization tower, includes the following steps: S1: Real-time acquisition of flue gas flow signal at the air inlet of the tower and transmission to the control system; S2: The control system determines the target opening of the steering blades based on the flue gas flow signal; S3: The control system sends control commands to the drive assembly, which drives the rotating shaft to rotate, causing the steering blades to rotate to the target opening, and performs closed-loop adjustment based on the actual angle fed back by the angle sensor. S4: The flue gas forms a rotating and rising turbulent flow after passing through the deflector blades.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses multiple adjustable steering blades evenly arranged circumferentially along the inner wall of the tower, and each blade is independently equipped with a drive and feedback actuator consisting of a servo stepper motor, a reducer, and an angle sensor. This allows the control system to precisely drive the blades to rotate to the target opening based on real-time flue gas flow signals. Thus, when the boiler is running at low load, the blade opening is reduced to maintain sufficient swirling intensity and avoid uneven airflow distribution. When running at high load, the opening is increased to reduce flow resistance. This active and precisely adjustable mechanical structure fundamentally overcomes the shortcomings of fixed flow guiding devices that cannot adapt to load fluctuations, ensuring the stable and efficient operation of the desulfurization tower across the entire operating range. 2. The steering blade of this invention adopts a specific airfoil structure. The guide surface designed on its surface can effectively transform the vertically rising flue gas into a rotating upward turbulent flow. This flow field change directly caused by the mechanical structure significantly increases the travel and residence time of the flue gas in the tower, disrupts the push flow, and promotes intense mixing and contact between the flue gas and the desulfurization slurry. The serrated turbulence structure further set at the edge of the blade can generate vortices, further enhancing the mixing effect. The flow field optimization brought about by this structure directly improves the absorption and mass transfer efficiency of sulfur dioxide. 3. The mechanical layout of the multi-blade steering system of the present invention, which is arranged circumferentially and can be independently driven and adjusted, provides a physical basis for solving the problem of airflow deviation caused by uneven flue gas injection. By cooperating with multiple sets of wind pressure measuring devices correspondingly set on the tower wall, the control system can obtain circumferential pressure distribution information and make differentiated opening adjustments to each set of blades, thereby actively compensating for airflow deviation and making the flow field distribution on the entire tower cross section more uniform. This structural design ensures that the desulfurization reaction space is fully utilized, avoids local short circuits or dead zones, and makes the desulfurization effect more stable and reliable. 4. The mechanical structure design of the device of the present invention fully considers the harsh environment of high corrosion, high wear and possible scaling inside the desulfurization tower. The steering blades are made of corrosion-resistant and wear-resistant materials and are coated with wear-resistant and anti-corrosion coatings. The key parts of the rotating shaft passing through the tower wall are equipped with a cartridge mechanical seal, which effectively prevents flue gas leakage. The drive mechanism has a self-locking function, which can lock the blade angle when the power is off, preventing the blade position from changing or being damaged due to flue gas impact. These structural features together ensure the reliability and maintenance-free nature of the device in long-term operation. 5. The drive mechanism, angle sensor and sealing components of the present invention are all integrated on a specially welded fixed base assembly on the outside of the tower body. This structural design of external moving parts allows installation, debugging and subsequent maintenance to be carried out without entering the tower, which greatly reduces the difficulty of construction and maintenance, safety risks and construction period costs. At the same time, the modular design also makes it easy to install the device on newly built or renovated desulfurization towers. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other, and the described embodiments are only some embodiments of the present invention, not all embodiments.

[0018] Detailed implementation method: See Figure 1-8This embodiment describes a flue gas dynamic steering and turbulence enhancement device for a wet magnesium desulfurization tower, comprising a tower body 2, a spray assembly 4, a blade support 7, a tower inlet 8, a sealing assembly 13, a rotating shaft 14, steering blades 15, and a control system. The spray assembly 4 is located at the upper part of the tower body 2, and the tower inlet 8 is located at the lower part. The tower body 2 serves as the container for the flue gas desulfurization reaction, adopting a combined flue gas and tower structure. The spray assembly 4 typically consists of a main pipe, branch pipes, and multiple nozzles, and its function is to atomize the desulfurization slurry. The sulfur-containing flue gas to be treated is evenly sprayed onto the cross-section of the tower body 2. It enters the tower body 2 through the air inlet 8. Multiple steering blades 15 are arranged circumferentially along the inner wall of the tower body 2 between the air inlet 8 and the spray assembly 4. Each steering blade 15 is fixedly connected to a rotating shaft 14, which is rotatably installed inside the tower body 2. Each rotating shaft 14 is connected to a drive assembly, and both ends of the rotating shaft 14 are rotatably supported on the tower body 2, causing the steering blades 15 to rotate around the rotating shaft 14. The component drives the rotating shaft 14 to rotate, which in turn drives the steering blade 15 to rotate, thereby controlling the flow direction of the flue gas. An angle sensor 12 is installed on the rotating shaft 14 to sense the angular position of the steering blade 15. The control system is communicatively connected to the drive component and the angle sensor 12 and receives the flue gas flow signal. The control system controls the drive component to drive the rotating shaft 14 to rotate according to the flue gas flow signal, thereby adjusting the opening of the steering blade 15. The cross-section of the steering blade 15 is airfoil-shaped. The design principle of the airfoil cross-section is that when the flue gas flows through, a pressure difference will be generated on the surface of the steering blade 15, which can more efficiently and smoothly convert part of the kinetic energy of the flue gas into the energy of rotational motion, guide the flue gas to generate a tangential velocity component, form a swirling flow, and at the same time, the flow loss is relatively small. The edge of the steering blade 15 is provided with a serrated structure, which can destroy the laminar boundary layer of the flue gas, intensify the turbulent mixing between the flue gas and the desulfurization slurry droplets, and further enhance the mass transfer process of the gas and liquid phases.

[0019] The working principle of this invention is as follows: Based on the received real-time flue gas flow signal, the control system calculates the optimal target blade opening under the current operating conditions according to the preset control strategy. Then, the control system sends a command to the drive component, which drives the rotating shaft 14 to rotate, thereby rotating the steering blade 15 to the target angle. By adjusting the opening of the steering blade 15, the flow direction and velocity distribution of the flue gas when passing through the blade channel are changed.

[0020] The drive mechanism includes a servo stepper motor 9 and a reducer 10. The servo stepper motor 9 is connected to a rotating shaft 14 via the reducer 10. An angle sensor 12 is also installed on the rotating shaft 14. The reducer 10 is typically a worm gear reducer. The reducer 10 is used to convert the high-speed, low-torque power output by the servo stepper motor 9 into the low-speed, high-torque power required to drive the steering blade 15. At the same time, the worm gear reducer 10 has a self-locking function, which can prevent the steering blade 15 from changing position due to the impact of flue gas when the power is off. The output shaft of the servo stepper motor 9 is connected to the input shaft of the reducer 10 via a coupling. The output shaft of the reducer 10 is coaxially connected to one end of the rotating shaft 14. The angle sensor 12 is directly installed on the extended end of the rotating shaft 14 and rotates synchronously with the rotating shaft 14. It is used to detect the actual rotation angle of the rotating shaft 14 in real time and feed the signal back to the control system. Thus, together with the servo stepper motor 9, a high-precision closed-loop position control system is formed to ensure that the steering blade 15 can be accurately and quickly positioned to the required angle.

[0021] The drive mechanism also includes a reducer mounting base 11, which is located on the outer wall of the tower body 2. The servo stepper motor 9 and the reducer 10 are mounted on the reducer mounting base 11. The reducer mounting base 11 is a rigid support structure, usually welded from steel profiles. This mounting base is fixed to the outer wall of the tower body 2 by welding or high-strength bolts. The servo stepper motor 9 and the reducer 10 are mounted as a whole component on the reducer mounting base 11 by bolts, so that the entire drive mechanism is located outside the tower body 2, which facilitates installation, debugging, daily maintenance and repair without entering the interior of the tower body 2, thus improving the safety and convenience of operation. At the same time, the external installation also avoids the drive mechanism being directly exposed to the harsh environment of corrosion and humidity inside the tower body 2, improving its working reliability and service life.

[0022] The flue gas dynamic steering and turbulence enhancement device of the wet magnesium desulfurization tower also includes a wind pressure measuring device 6. The wind pressure measuring device 6 is installed through the wall of the tower body 2 and located above the steering blade 15. The wind pressure measuring device 6 is selected as an anti-clogging pressure transmitter or pressure tapping pipe. Multiple measuring holes are evenly opened in the circumferential direction on the wall of the tower body 2 above the steering blade 15. The sensing end of each wind pressure measuring device 6 passes through and is sealed and fixed in these holes. It monitors the static pressure at different circumferential positions on the annular cross section of the tower body 2 above the steering blade 15 in real time. Since the change of the opening of the steering blade 15 will affect the downstream flow field distribution, resulting in pressure unevenness, by analyzing these circumferential pressure data, the control system can determine whether there is a flow deviation or uneven distribution of the airflow in the tower, thereby providing a basis for the differentiated adjustment of the opening of the steering blade 15 and realizing more balanced flow field control.

[0023] The flue gas dynamic diversion and turbulence enhancement device of the wet magnesium desulfurization tower also includes a compressed air backflush assembly 5. The compressed air backflush assembly 5 is connected to the wind pressure measuring device 6. The compressed air backflush assembly 5 includes a compressed air source, pipeline, solenoid valve and nozzle. The pipeline of the compressed air backflush assembly 5 is connected to the pressure tapping pipe or measuring chamber of the wind pressure measuring device 6. The control system triggers the solenoid valve to open briefly at a set time interval or according to the pressure difference signal. A high-pressure compressed air pulse is blown back into the pressure tapping channel of the wind pressure measuring device 6, sweeping the slurry or ash accumulated at the pressure tapping port back into the tower body 2, thereby keeping the pressure tapping pipeline unobstructed and ensuring the accuracy and continuity of pressure measurement.

[0024] The flue gas dynamic diversion and turbulence enhancement device of the wet magnesium desulfurization tower also includes a backwashing component 3, which is located above the spray component 4. In the wet desulfurization tower, a demister is installed above the spray component 4. The function of the demister is to capture and remove desulfurization slurry droplets carried in the purified flue gas through collision, centrifugation, and other mechanisms, preventing droplet-borne corrosion of downstream equipment and gypsum rain. The backwashing component 3 is used to periodically clean the demister and the outer surface of the nozzles of the spray component 4 to remove gypsum, soot, and other solid deposits that may accumulate, preventing scaling and blockage, thereby ensuring the gas-liquid separation efficiency of the demister and the spray effect of the spray component, and maintaining the long-term stable operation of the system. The spray component 4 is used to atomize the magnesium oxide alkaline solution through the nozzles and form a spray pattern across the entire cross-section of the desulfurization tower. The liquid droplets are sprayed downwards in a uniform manner. When the flue gas flows from bottom to top, it comes into countercurrent contact with the magnesium oxide alkaline droplets. The sulfur dioxide in the droplets reacts chemically with the magnesium oxide alkaline solution and is absorbed and removed, thereby achieving flue gas desulfurization. The backwashing component 3 typically includes a high-pressure cleaning water pump, corresponding valve groups, pipelines, and nozzles. During system shutdown or low-load operation, the cleaning program is started. The high-pressure cleaning water pump draws clean water as the rinsing medium and performs rinsing operations through two independent pipeline systems. One pipeline is used to rinse the demister, and the other pipeline leads to the area of ​​the spray component 4. Usually, nozzles or spray pipes are set above or to the side of the spray layer to rinse the branch pipes and outer surfaces of the nozzles of the spray component 4. The two rinsing operations can be carried out sequentially or simultaneously, and the valves are automatically controlled by the control system.

[0025] The flue gas dynamic diversion and turbulence enhancement device of the wet magnesium desulfurization tower also includes a platform 1. The platform 1 is set outside the tower body 2. The platform 1 is usually a steel grating platform, equipped with guardrails and ladders to form a safe operating passage. The platform 1 is arranged around the tower body 2, especially in the area of ​​the tower body 2 where components such as drive mechanisms and sealing components that require regular inspection or maintenance are installed.

[0026] The flue gas dynamic steering and turbulence enhancement device of the wet magnesium desulfurization tower also includes a blade support 7 and a bushing 16. The blade support 7 is disposed inside the tower body 2 and located between the tower inlet 8 and the spray assembly 4. The bushing 16 is disposed on the blade support 7, and the end of the rotating shaft 14 is rotatably mounted in the bushing 16. The blade support 7 is a regular 12-sided polygon, preferably a tapered or cylindrical frame structure of a regular 12-sided polygon. The regular 12-sided design is to correspond with the radial direction of the 12 steering blades 15. The structure is matched so that each side corresponds to a support point of the steering blade 15, making the structure uniform and compact in terms of force. A bushing 16 is installed on each side of the blade support seat 7. The inner end of the rotating shaft 14 is inserted into the bushing 16 and can rotate freely relative to the bushing 16. The bushing 16 is provided with a sliding bearing or bushing, which supports the rotating shaft 14 and restricts its radial movement, allowing the rotating shaft 14 to rotate only around its own axis. Thus, together with the bearing at the tower wall, it forms a two-point support for the rotating shaft 14, ensuring that the steering blade 15 operates smoothly and is accurately aligned.

[0027] The flue gas dynamic steering and turbulence enhancement device of the wet magnesium desulfurization tower also includes a sealing component 13. The rotating shaft 14 is installed through the wall of the tower body 2. The sealing component 13 is installed at the outlet of the rotating shaft 14 and connected to the drive component. The sealing component 13 is installed at the outlet of the rotating shaft 14 and is located between the drive component and the tower wall, thereby completely isolating the tower environment from the external atmosphere and drive components, ensuring reliable sealing even when the shaft rotates continuously, preventing flue gas leakage and external air intake. The sealing component 13 is usually a cartridge mechanical seal. Its design principle is to use a pair of high-hardness and wear-resistant sealing rings perpendicular to the axis to fit tightly together under the action of spring and medium pressure to form a relatively rotating sealing end face.

[0028] A method for dynamic flue gas diversion and turbulence enhancement, applied to a flue gas dynamic diversion and turbulence enhancement device in a wet magnesium desulfurization tower, includes the following steps: S1: Real-time acquisition of flue gas flow signal at the air inlet 8 of the tower body and transmission to the control system. This signal is continuously measured by the flow measuring instrument 8 installed on the inlet flue and transmitted to the control system 8 in real time through analog or digital communication 8. S2: The control system determines the target opening of the steering blade 15 based on the received real-time flue gas flow signal. The control system has a pre-stored control strategy, which is a mapping table of flue gas flow and optimal blade opening, or a dynamic calculation model based on PID algorithm or more advanced optimization algorithm. The control system substitutes the current flow value into the strategy and calculates the optimal blade angle setting value corresponding to the current operating condition. S3: The control system sends control commands to the drive assembly, which drives the rotating shaft 14 to rotate, causing the steering blade 15 to rotate to the target opening. The control system performs closed-loop adjustment based on the actual angle fed back by the angle sensor 12. The control system compares the target opening with the actual opening fed back by the angle sensor 12, generates a deviation signal, and outputs a drive signal to the servo stepper motor 9 after the controller calculates the deviation. The servo stepper motor 9 drives the rotating shaft 14 and the steering blade 15 to rotate through the reducer 10. The angle sensor 12 monitors the actual rotation angle of the shaft in real time and feeds back the deviation, forming a closed-loop control loop until the deviation between the actual opening and the target opening is within the allowable error range, thus completing the precise positioning. S4: After the flue gas passes through the adjusted deflector blades 15, it forms a rotating upward turbulent flow. When the flue gas flows vertically upward at a certain velocity through the airfoil-shaped deflector blades 15 with a certain angle, the deflector blades 15 guide the flue gas and give it a tangential velocity component. The combined action of multiple deflector blades 15 transforms the flue gas flow across the entire tower cross section from its original vertical upward flow to a spiral upward flow rotating around the tower's centerline. This intense rotating turbulence greatly increases the flue gas's travel distance and residence time within the tower, disrupting the laminar boundary layer and allowing the flue gas to fully and violently mix and contact with the desulfurization slurry sprayed from top to bottom. This significantly enhances the gas-liquid mass transfer process and improves the desulfurization reaction efficiency.

These embodiments do not exhaustively describe all details, nor do they limit the invention to the specific embodiments described.
