Description

Technical Field

[0001] This application belongs to the technical field of desulfurization tower cleaning equipment, specifically relating to a desulfurization tower demister flushing water device. Background Technology

[0002] In recent years, with the widespread application of flue gas desulfurization cleaning paste in the thermal power, metallurgy and chemical industries, desulfurization towers are generally equipped with baffle plate demisters. In order to ensure the long-term stable operation of the demister, the existing equipment is generally connected to multiple fixed nozzles through water supply pipes. The surface of the baffle plate demister is regularly rinsed by the multiple fixed nozzles connected to the water supply pipes to reduce the adhesion of slurry, gypsum crystals and dust.

[0003] Currently, existing desulfurization tower demister flushing water devices, in actual use, inevitably cause nozzle blockage and scale buildup at the baffles, nozzle inner walls, or nozzle holes due to insufficient water supply. Simultaneously, the reaction process within the desulfurization tower also causes other impurities to accumulate on the nozzle filter screen, reducing the water spray range or causing deflection, leading to problems such as excessively strong local flushing and insufficient flushing of edge areas. This also increases the frequency of manual disassembly, cleaning, and maintenance, affecting the continuous and stable operation of the desulfurization system. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose a flushing water device for a desulfurization tower demister to reduce the probability of filter clogging, extend the maintenance cycle of the nozzles to reduce the frequency of disassembly, cleaning and maintenance, and improve the stability of the desulfurization system operation.

[0027] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] The desulfurization tower demister flushing water device of this invention is installed inside the desulfurization tower and includes: a filter assembly, a flow guiding assembly 3, a water supply pipe 1, and a spray pipe 2. The water supply pipe 1 is detachably connected to the spray pipe 2. The flow guiding assembly 3 is installed inside the spray pipe 2 and includes a fixing frame 31, a flow guiding cover 32, and a flow guiding blade component 33. The flow guiding blade component 33 is rotatably installed on the flow guiding cover 32. The fixing frame 31 is connected to the inner wall of the spray pipe 2, and the bottom of the fixing frame 31 is connected to the flow guiding cover 32. The filter assembly is installed inside the spray pipe 2 and below the flow guiding assembly 3. The filter assembly includes an upper filter screen 6, a lower filter screen 7, and a ball bearing 8. The upper filter screen 6 and the lower filter screen 7 are installed on the inner wall of the spray pipe 2 and are spaced apart axially in the spray pipe 2. The ball bearing 8 is installed between the upper filter screen 6 and the lower filter screen 7.

[0029] The desulfurization tower demister flushing water device of the present invention reduces the probability of filter clogging, extends the maintenance cycle of the nozzles to reduce the frequency of disassembly, cleaning and maintenance, and improves the stability of the desulfurization system operation.

[0030] Specifically, such as Figures 1 to 8 As shown, the inlet of water supply pipe 1 is connected to a water source. For example, if the liquid tank contains water, one end of the water pump is connected to the liquid tank, and the other end of the water pump is connected to the inlet of water supply pipe 1 through a flow valve. It is understandable that during maintenance, the water initially used in the desulfurization system will inevitably develop scale, or the filter screen of spray pipe 2 will develop crystals from the flue gas reaction.

[0031] A fixing frame 31 is installed at the top of the spray pipe 2, and its lower end is connected to a guide shroud 32. A guide vane component 33 is rotatably fitted onto the guide shroud 32. Under the impact of the water flow, the guide vane component 33 rotates, changing the direction of the water flow so that the water flow impacts the rolling ball 8, causing the rolling ball 8 to rotate between the upper and lower filter screens 7. During the movement, it can both collide and break up larger impurities, scale particles, or clumps entering the spray pipe 2, and also rub against the inner wall of the spray pipe 2 to disturb and clean the mud, scale, or slurry crystals attached to the inner wall of the spray pipe 2. This reduces the accumulation of impurities inside the spray pipe 2 and lowers the risk of blockage of the spray pipe 2 and its bottom water outlet structure. It also avoids the problem of water flow being concentrated in one position, resulting in excessive local flushing intensity and insufficient flushing of surrounding areas.

[0032] The desulfurization tower demister flushing water device of this invention is detachably connected to the spray pipe 2 via a water supply pipe 1, facilitating disassembly and maintenance. The flow guiding component 3 and the filter component inside the spray pipe 2 work together. Under the impact of the water flow, the flow guiding blade component 33 rotates and changes the direction of the water flow, driving the rolling ball 8 to continuously tumble between the upper and lower filter screens 7. On the one hand, this can collide and break up large particles, scale, and crystals entering the spray pipe 2; on the other hand, the frictional contact between the rolling ball 8 and the inner wall of the pipe can disturb and remove attached mud, scale, or slurry crystals, thereby significantly reducing internal accumulation, lowering the probability of filter and nozzle clogging, extending the nozzle maintenance cycle, reducing the frequency of disassembly, cleaning, and maintenance, and ensuring the long-term stable operation of the desulfurization system.

[0033] Furthermore, the rotation of the guide vane component 33 makes the water flow distribution more uniform, avoiding the problem of excessive local flushing intensity and insufficient flushing of surrounding areas caused by the water flow being concentrated in a certain position in traditional flushing. This ensures the consistency of flushing coverage and effect, and further improves the cleaning efficiency of the demister and the overall operational stability of the desulfurization system.

[0034] Furthermore, the guide vane component 33 includes a collar 332 and blades 331. The blades 331 are arranged at uniform intervals around the collar 332. Through the rotational design of the collar 332 and the circumferential blades 331, the water flow direction is uniformly dispersed and forms a spiral or swirling flow pattern, avoiding the drawbacks of traditional direct-flow water spraying which is concentrated at only one position, resulting in excessively strong local impact and insufficient rinsing of surrounding areas. This uniform flow field not only drives the rolling ball 8 to move more fully in all directions, expanding the cleaning range, but also makes the distribution of rinsing water on the cross-section of the spray pipe 2 more balanced, thereby ensuring that the coverage area and intensity of the rinsing water sprayed from the nozzle are consistent, greatly improving the overall cleaning effect of the demister, further ensuring the service life of the desulfurization tower, or extending the maintenance cycle.

[0035] In some embodiments, the rolling ball 8 is hollow and made of ceramic. The hollow structure of the rolling ball 8 reduces its weight and moment of inertia. Under the impact of the rotating water flow driven by the guide vane component 33, the hollow rolling ball 8 is easier to start and continuously roll, consuming less kinetic energy of the water flow. This results in more intense collision and friction under the same water pressure, effectively improving the efficiency of breaking up scale and crystals. Simultaneously, due to the reduced weight, the impact force of the rolling ball 8 on the upper and lower filter screens 7 and the inner wall of the spray pipe 2 is buffered, reducing deformation or wear of the filter screens caused by repeated impacts during long-term operation and extending the overall service life of the filter assembly. The ceramic material of the rolling ball 8 gives it high hardness, high wear resistance, and excellent resistance to acid and alkali corrosion. In the harsh corrosive environment of the desulfurization tower, the ceramic rolling ball 8 is not prone to rust, peeling, or chemical degradation, maintaining a regular spherical shape and surface smoothness for a long time, avoiding secondary pollution of the water body by debris generated from its own wear. Furthermore, the dense and smooth ceramic surface does not easily adhere to mud, sand, or slurry crystals, exhibiting a certain degree of self-cleaning property. This ensures that the rolling balls maintain their agitation and cleaning effect during long-term operation, further guaranteeing the reliability and stability of the flushing water device. Furthermore, there are multiple rolling balls 8, which are arranged between the upper filter screen 6 and the lower filter screen 7.

[0036] This embodiment creates a dense cluster of moving particles within a limited space by placing multiple hollow ceramic balls 8 between the upper filter screen 6 and the lower filter screen 7. Driven by the rotating water flow, each ball 8 tumbles and collides with each other, increasing the probability of shearing and breaking down impurities such as scale and crystals, which is superior to the limited range of action of a single ball 8. Furthermore, the more uniform distribution of multiple balls 8 across the pipe diameter cross-section allows for coverage of all areas around the spray pipe 2, eliminating cleaning dead zones that a single ball cannot reach, thus significantly improving the overall anti-clogging effect. The multiple balls 8 form a dynamic, moving abrasive layer between the upper and lower filter screens 7. When water carrying impurities passes through the filter screen, the random movement of the balls 8 continuously agitates and disturbs the particles deposited on the filter screen surface, preventing impurities from bridging or accumulating at the filter screen openings. Simultaneously, the balls 8 repeatedly contact the inner wall of the spray pipe 2 during their movement, creating a full-circumferential, multi-point friction cleaning effect, further enhancing the removal of deposits from the inner wall. Even if some of the balls 8 fail due to jamming or wear, the remaining balls 8 can continue to function, ensuring the fault tolerance and reliability of the filter assembly during long-term operation and extending the maintenance cycle.

[0037] In some embodiments, the pore size of the upper filter screen 6 is larger than that of the lower filter screen 7. The large pore size design of the upper filter screen 6 ensures that sufficient flushing water flow can quickly enter the area of ​​the rolling balls 8, providing sufficient kinetic energy to drive multiple ceramic hollow rolling balls 8. This avoids weakening the agitation and crushing effect of the rolling balls 8 due to excessive filter screen resistance. As the first line of defense, the upper filter screen 6 first intercepts larger particle size impurities, crystals, and silt clumps, preventing them from directly entering the active area of ​​the rolling balls 8. The lower filter screen 7, as a fine filtration layer, intercepts the smaller particle size particles remaining after being crushed by the rolling balls 8. This graded configuration allows for a reasonable distribution of solid phase load between the two filter screens, preventing rapid clogging of a single filter screen surface due to the accumulation of a large amount of impurities, and extending the overall service life and cleaning / replacement cycle of the filter screen.

[0038] In some embodiments, the flow guiding assembly 3 further includes a connecting shaft 34, an elastic member 35, and a spray platform 36. One end of the connecting shaft 34 is connected to the bottom of the flow guiding cover 32, and the other end of the connecting shaft 34 passes through the upper filter screen 6 and the lower filter screen 7 and is connected to the elastic member 35. The lower end of the elastic member 35 is connected to the spray platform 36.

[0039] Specifically, such as Figures 1 to 8 As shown, the upper end of the connecting shaft 34 is connected to the lower end of the guide shroud 32, the lower end of the connecting shaft 34 is connected to the upper end of the elastic component 35, and the lower end of the elastic component 35 is connected to the spray platform 36.

[0040] The vibration of the elastic component 35 acts on the outlet water flow through the spray platform 36, creating a pulsating effect in the outlet water. This effectively flushes the inlet area of ​​the spray head, forming a full-process, multi-layered anti-clogging system from the top of the spray pipe 2 to the outlet, thus improving the operational reliability of the desulfurization system under long-term high turbidity conditions. Simultaneously, the up-and-down movement of the spray platform 36 driven by the elastic component 35 removes crystals or sludge adhering to the inner wall of the spray pipe 2.

[0041] In some embodiments, the flow guiding component further includes an upper flow guiding ring 37 and a lower flow guiding ring 38. Both the upper flow guiding ring 37 and the lower flow guiding ring 38 are provided on the inner wall of the spray pipe 2. The radial dimension of the spray platform 36 gradually increases in the axial direction of the spray pipe 2 towards the outlet of the adjacent spray pipe 2, and the radial dimension of the lower flow guiding ring 38 gradually decreases in the radial direction of the spray pipe 2 towards the outlet of the adjacent spray pipe 2.

[0042] Specifically, such as Figures 1 to 8As shown, the lower end of the upper guide ring 37 is connected to the upper end of the lower guide ring 38. The radial dimension of the upper guide ring 37 in the spray pipe 2 gradually increases from top to bottom, while the radial dimension of the lower guide ring 38 in the spray pipe 2 gradually decreases from top to bottom. When the elastic component 35 extends and retracts, the outer circumferential surface of the spray platform 36 will rub or impact with the inner wall surface of the lower guide ring 38. Since the radial dimension of the spray platform 36 increases downward while the radial dimension of the lower guide ring 38 decreases downward, the annular flow area between the two exhibits a gradually converging pattern in the axial direction.

[0043] When the elastic component 35 extends and retracts, the axial overlap position of the spray platform 36 and the lower guide ring 38 changes, causing the throttling area of ​​the annular gap to change in real time. The extension and retraction displacement causes the point where the jet impacts the baffle 5 to move radially, i.e., a sweeping effect. Combined with the pulsating impact, the originally fixed impact point becomes a dynamic impact trajectory that moves back and forth. This covers a larger area of ​​the baffle 5, eliminating dead zones from continuous single-point impacts, and simultaneously applying an alternating impact and relaxation process to the entire surface of the baffle 5, which helps the detached dirt to be washed away by the water flow in time, preventing secondary deposition.

[0044] In some embodiments, the water spray platform 36 has a hollow structure, with an inlet at the top and a water spray plate 39 at the bottom. The water spray plate 39 has a plurality of filter holes, and the filter holes are inclined in a direction away from the axis of the water spray platform 36.

[0045] Specifically, such as Figures 1 to 8 As shown, the water spray platform 36 has an inlet at its upper end and a spray plate 39 at its lower end. Multiple small holes on the spray plate 39 decompose the concentrated total flow into multiple independent jets. Due to the flow obstruction effect of the plate, a stable back pressure is formed in the cavity, forcing the water flow to be evenly distributed to each filter hole. This avoids the short-circuiting phenomenon caused by inlet flow deviation, where the flow rate is large near the center hole and small at the edge hole, thus achieving a spatially uniform distribution of jet energy. When the water flows through the inclined holes, it gains a radially outward tangential velocity. This inclined jet generates a lateral sweeping force on the inner surface of the spray plate 39 before leaving the plate. At the same time, the water before entering the spray platform 36 rotates to a certain extent under the action of the guide shroud 32 and the guide vane component 33. Under the action of centrifugal force, the rotating water flow in the hollow cavity throws the denser particles to the periphery of the cavity, away from the center area of ​​the filter hole, making them less likely to settle vertically and clog the orifice. This achieves active hydraulic anti-clogging of the filter holes.

[0046] In some embodiments, the outer peripheral surface of the spray platform 36 is provided with multiple flow-guiding grooves. When the spray platform 36 extends and retracts at high speed, the fluid in the grooves generates a dynamic pressure effect, forming an extremely thin dynamic water film between the contact surfaces, transforming the original solid-solid direct friction into liquid-solid shear friction. This reduces the coefficient of friction, decreases wear on the outer peripheral surface, and effectively suppresses stick-slip vibration under high-frequency extension and retraction motion, ensuring smooth movement. Simultaneously, the grooves act as chip removal channels. During relative movement, small particles scraped off or originally present in the mating gaps are collected in the grooves and directionally discharged with axial movement and water flow, preventing particles from embedding into the smooth mating surface and causing severe scratches or roughening. This protects the outer peripheral surface of the spray platform 36 and the inner wall of the flow-guiding ring, extending its service life.

[0047] In some embodiments, the elastic member 35 includes a sleeve 351, a limiting ring 352, a guide shaft 353, and a spring 354. One end of the sleeve 351 is sleeved on the connecting shaft 34, and the other end of the sleeve 351 is connected to the water spray plate 39. The connecting shaft 34 is provided with a limiting ring 352 to limit the movement of the sleeve 351. A blind hole 341 is provided at the lower end of the connecting shaft 34. One end of the guide shaft 353 extends into the blind hole 341 of the connecting shaft 34, and the other end of the guide shaft 353 is connected to the water spray plate 39. A spring 354 is sleeved on the guide shaft 353, and one end of the spring 354 is in contact with the limiting ring 352, and the other end is in contact with the water spray plate 39.

[0048] Specifically, such as Figures 1 to 8 As shown, the upper end of the sleeve 351 is fitted inside the connecting shaft 34, and a limiting ring 352 is also fitted on the connecting shaft 34 to limit the excessive downward movement of the sleeve 351. At the same time, a blind hole 341 is provided at the lower end of the connecting shaft 34, and the lower end of the guide shaft 353 extends into the blind hole 341. The lower end of the connecting shaft 34 is connected to the water spray plate 39, the lower end of the guide shaft 353 is connected to the water spray plate 39, the upper end of the spring 354 contacts the limiting ring 352, and the lower end of the spring 354 is connected to the water spray plate 39.

[0049] The guide shaft 353 provides radial support and limits the spring 354 when it is compressed. It restrains the spring 354 from potential radial drum-like expansion or S-shaped instability (i.e., compression rod instability) that may occur under compression, ensuring that the spring 354 always extends and contracts linearly along the axial direction. This maintains the directionality and stability of the elastic force and also prevents irregular friction or scraping between the spring 354 and adjacent components, extending the fatigue life of the spring 354.

[0050] Furthermore, the guide shaft 353 is provided with a vent hole 3531 extending through the guide shaft in the vertical direction for ventilation inside the sleeve 351. It can also be understood that the vent hole 3531 is connected to one of the multiple filter holes.

[0051] The limiting ring 352 provides a first-level limit on the downward sliding of the sleeve 351, preventing the sleeve 351 from disengaging from the connecting shaft 34. Simultaneously, the blind hole 341 limits the insertion depth of the guide shaft 353, preventing excessive compression and impact on the interior of the connecting shaft 34. Even if the spring 354 breaks due to long-term fatigue or the water pressure is abnormally high, the dual-limiting structure rigidly limits the maximum stroke of the spray platform 36, preventing components from flying off or colliding and damaging the downstream baffle plate 5, ensuring the safety of the equipment under extreme operating conditions.

[0052] In some embodiments, a damping sleeve 4 is also included, which is disposed on the guide shaft 353 and contacts the inner wall of the blind hole 341. The frictional resistance provided by the damping sleeve 4 can effectively convert mechanical vibration energy into heat energy and dissipate it, significantly reducing the resonance peak and suppressing excessive bouncing of the water jet platform 36.
