Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for desulfurization towers, and in particular to a desulfurization tower demister with a flushing and anti-scaling structure. Background Technology

[0002] In industrial flue gas desulfurization processes, the desulfurization tower is the core equipment, and the demister, as a key component within the desulfurization tower, primarily functions to remove mist droplets and slurry particles carried in the flue gas, preventing corrosion of subsequent equipment and reducing pollutant emissions.

[0003] Based on the above, existing desulfurization tower demisters have the following shortcomings: Structural design limitations lead to scale formation and increased system resistance. The blades often employ planar or simple angled designs, making it easy for slurry components such as calcium sulfate and calcium sulfite in the droplets to deposit on the blade surface and form scale. As the scale layer thickens, it not only significantly reduces the flue gas flow cross-section but also disrupts the flow field distribution on the blade surface, especially forming vortex zones at the angles, resulting in decreased droplet capture efficiency. Furthermore, the fixed-angle spray pipes used for rinsing are limited by the spatial structure and water flow diffusion angle, resulting in numerous blind spots in the rinsing water coverage area. The rinsing coverage is insufficient in key areas such as blade angles and the back of the guide vanes. Moreover, simple rinsing leaves residual water droplets on the blades, making it easier for dirt to adhere. Utility Model Content

[0004] This utility model relates to a desulfurization tower demister with a flushing and anti-scaling structure. By switching the electromagnetic control valves at the front and rear ends of the gas-liquid common pipe, it is possible to inject liquid to flush or inject air to dry the blades of the demister body. Liquid flushing can remove slurry residue in time, while air drying can prevent residual moisture on the blades from causing dirt to adhere. The dual function further enhances the anti-scaling effect.

[0005] The above objectives are achieved through the following scheme: A desulfurization tower demister with a flushing and anti-scaling structure comprises a desulfurization tower body; the outer wall of the desulfurization tower body is rectangular in the middle and has a cavity; a gas-liquid common pipe is fixedly installed on the left side wall of the rectangular outer wall of the desulfurization tower body; a swing control plate is slidably connected to the right side wall of the rectangular outer wall of the desulfurization tower body; protective side plates are fixedly installed on both the left and right side walls of the rectangular outer wall of the desulfurization tower body; a demister body is fixedly installed inside the desulfurization tower body; swing flushing rods are provided on the upper and lower sides between the multiple parallel blades of the demister body; the left and right ends of the swing flushing rods are rotatably connected to the side wall of the desulfurization tower body; and a drive motor is fixedly installed in the middle of the right rear inner wall of the rectangular outer wall of the desulfurization tower body.

[0006] The aforementioned desulfurization tower demister with a flushing and anti-scaling structure has two rows of through-rotating holes symmetrically opened in the middle of the inner wall of the desulfurization tower body. A swing flushing rod is slidably connected in the through-rotating holes. A rectangular sliding guide groove is opened in the middle of the outer wall of the right side of the desulfurization tower body. Concave guide arc grooves are opened at both the upper and lower ends of the left side of the sliding guide groove.

[0007] The aforementioned desulfurization tower demister with a flushing and anti-scaling structure has blades that are arranged at equal intervals in the demister body and are trapezoidal in shape with a convex rear section in the middle. The bending points of the blades in the demister body are all curved arcs, and a flow guiding protrusion is provided in the middle of the rear sidewall of the blades in the demister body.

[0008] The aforementioned desulfurization tower demister with a flushing and anti-scaling structure has flushing spray heads evenly spaced at the bottom of the swing flushing rod on the upper side of the demister body, and flushing spray heads evenly spaced on both the upper and lower sides of the swing flushing rod on the lower side of the demister body. The flushing spray heads are trapezoidal in shape, and a control arm is fixedly connected to the right end of both the upper and lower sets of swing flushing rods. The control arms face opposite sides, and a long strip-shaped swing groove is opened at the end of the control arm.

[0009] The aforementioned desulfurization tower demister with a flushing and anti-scaling structure has sliding protrusions fixedly connected to the front side of the middle of the upper and lower ends of the left side wall of the swing control plate. The swing control plate is slidably connected to the sliding guide groove in the middle of the right outer wall of the desulfurization tower body, and the sliding protrusions are slidably connected to the guide arc groove opened in the sliding guide groove.

[0010] The aforementioned desulfurization tower demister with a flushing and anti-scaling structure has connecting columns symmetrically and equidistantly installed on the right side wall of the swing control plate. The connecting columns are slidably connected to the swing groove opened in the right end control arm of the swing flushing rod. The rear end of the swing control plate has a longitudinal reciprocating groove.

[0011] The aforementioned desulfurization tower demister with a flushing and anti-scaling structure has a drive disk fixedly connected to the left end of the drive shaft of the drive motor. A drive lever is eccentrically installed on the left side wall of the drive disk, and the drive lever is slidably connected in the reciprocating groove at the rear end of the swing control plate.

[0012] The aforementioned desulfurization tower demister with a flushing and anti-scaling structure is provided with an inverted conical sliding adapter at the connection between the gas-liquid common pipe and the left end of each swing flushing rod. Both ends of the sliding adapter are fitted with sealing gaskets, and electromagnetic control valves are installed at both ends of the gas-liquid common pipe. Beneficial effects

[0013] 1. The desulfurization tower body's through-rotation hole, sliding guide groove, and guide arc groove structure provide stable support and trajectory limit for the swing flushing rod, and provide precise guidance for the swing control plate, avoiding the flushing mechanism from deviating or jamming. At the same time, the convex trapezoidal blades, curved arc bends, and guide protrusions of the demister body optimize flue gas flow to reduce system resistance, reduce slurry residue accumulation to inhibit scale formation, and accelerate the dripping of accumulated liquid and improve droplet collision efficiency. The two work together to lay a solid structural foundation for the stable operation, scale prevention, and efficient demisting of the demister.

[0014] 2. The differentiated trapezoidal spray head of the swing flushing bar achieves full-surface flushing without blind spots. The control arm and swing chute ensure coordinated movement of the upper and lower flushing bars. The swing control plate ensures precise movement with the help of sliding protrusions and guide arc grooves. The "linear-circular" power conversion is achieved through the connecting column and swing chute, simplifying the structure and ensuring stable transmission. The eccentric drive structure of the drive motor drives the swing control plate to reciprocate regularly, realizing automatic uniform swing of the swing flushing bar, improving the degree of automation and buffering impact to reduce wear. All components form a complete automated flushing system, ensuring precise and efficient flushing, reducing manual intervention, and significantly improving the operational stability and durability of the demister.

[0015] 3. The inverted conical sliding adapter at the connection between the gas-liquid common pipe and the swing flushing rod enhances the joint's sealing performance while ensuring that the swing of the flushing rod is not affected. Combined with a sealing gasket, it further prevents flushing water leakage, avoiding water waste and corrosion of the outer wall of the desulfurization tower. By switching the electromagnetic control valves at the front and rear ends of the gas-liquid common pipe, liquid injection flushing or air injection drying can be achieved for the main blades of the demister. Liquid injection flushing can promptly remove slurry residue, while air injection drying can prevent residual moisture on the blades from causing scale adhesion. This dual effect further strengthens the anti-scaling effect, ensuring the long-term efficient operation of the demister. Attached Figure Description

Detailed Implementation

[0026] Please refer to Figures 1 to 9 As shown: This utility model provides a desulfurization tower demister with a flushing and anti-scaling structure, including a desulfurization tower body 1. The middle of the outer wall of the desulfurization tower body 1 is rectangular and has a cavity. A gas-liquid common pipe 6 is fixedly installed on the left side wall of the rectangular middle of the outer wall of the desulfurization tower body 1. A swing control plate 4 is slidably connected to the right side wall of the rectangular middle of the outer wall of the desulfurization tower body 1. Protective side plates 8 are fixedly installed on both the left and right side walls of the rectangular middle of the outer wall of the desulfurization tower body 1. A demister body 2 is fixedly installed inside the desulfurization tower body 1. Swing flushing rods 3 are provided on the upper and lower sides between the multi-layer parallel blades of the demister body 2. The left and right ends of the swing flushing rods 3 are rotatably connected to the side wall of the desulfurization tower body 1. A drive motor 5 is fixedly installed in the middle of the right rear inner wall of the rectangular middle of the outer wall of the desulfurization tower body 1.

[0027] The desulfurization tower body 1 has two rows of through-rotation holes 101 symmetrically opened in the middle of its inner wall. A swing flushing rod 3 is slidably connected in the through-rotation holes 101. A rectangular sliding guide groove 102 is opened in the middle of the outer wall of the right side of the desulfurization tower body 1. The upper and lower ends of the left side of the sliding guide groove 102 are both provided with concave guide arc grooves 10201. Therefore, the through-rotation holes 101 can limit the rotation trajectory of the swing flushing rod 3, prevent the flushing rod from radially deviating during the swing, and provide stable support for the flushing rod. The sliding guide groove 102 and the guide arc groove 10201 cooperate to provide a precise guide path for the sliding of the swing control plate 4, prevent the swing control plate 4 from jamming or deviating, and ensure the overall stability and smoothness of the flushing mechanism.

[0028] The blades of the demister body 2, which are arranged at equal intervals, are trapezoidal in shape with a convex rearward section in the middle. The bends of the blades in the demister body 2 are all curved arcs. A guide protrusion 201 is provided in the middle of the rear side wall of the blades of the demister body 2. Therefore, the trapezoidal blades with a convex rearward section in the middle of the demister body 2 can optimize the flow path of flue gas between the blades, reduce the generation of flue gas eddies, and reduce system resistance. The curved arc bends can prevent slurry residue from accumulating at the blade corners, reducing the starting point for scale formation. The guide protrusion 201 can accelerate the flow and dripping of condensate and rinsing liquid on the blade surface to the bottom of the blade, further reducing the adhesion time of slurry on the blade surface. From the structural design, it achieves the dual function of "anti-scaling + liquid guiding", while increasing the probability of collision between droplets and blades and enhancing the demisting efficiency.

[0029] Using the above technical solution, the desulfurization tower body 1 achieves stable support and trajectory limitation for the swing flushing rod 3, as well as precise guidance for the swing control plate 4, through the structural cooperation of the through rotating hole 101, sliding guide groove 102 and guide arc groove 10201. This avoids deviation and jamming during the operation of the flushing mechanism, ensuring the smoothness and stability of the overall operation. The demister body 2, through the design of the rear-convex trapezoidal blades, curved arc bends and guide protrusions 201, optimizes the flue gas flow to reduce system resistance, reduces slurry residue accumulation to inhibit scale formation, accelerates the dripping of accumulated liquid to achieve scale prevention and liquid guidance synergy, and improves the droplet collision efficiency to enhance the demisting performance. Together, they lay the structural foundation for the stable operation and core function realization of the demister.

[0030] The demister body 2 has equidistant rinsing spray heads 301 at the bottom of the swing rinsing rod 3 on the upper side, and equidistant rinsing spray heads 301 at both the upper and lower sides of the swing rinsing rod 3 on the lower side. The rinsing spray heads 301 are trapezoidal in shape. A control arm 302 is fixedly connected to the right end of both sets of swing rinsing rods 3, with the control arms 302 facing opposite sides. A long, narrow swing groove 303 is opened at the end of the control arm 302. Therefore, the rinsing spray heads 301 at the bottom of the swing rinsing rod 3 on the upper side of the demister body 2 can specifically rinse and demister. The lower surface of the upper blades of the device, the flushing spray heads 301 on both sides of the lower swing flushing rod 3 can simultaneously cover the upper and lower surfaces of the lower blades. Combined with the trapezoidal flushing spray head 301, which expands the flushing coverage of a single spray head, the entire surface of the demister blades is flushed without blind spots. The design of the control arm 302 and the swing slide 303 can synchronously transmit the movement of the subsequent swing control plate 4 to the upper and lower sets of swing flushing rods 3, ensuring that the swinging movements of the two sets of swing flushing rods 3 are coordinated and consistent, avoiding uneven blade force or insufficient flushing caused by unilateral flushing.

[0031] The swing control plate 4 has a sliding protrusion 401 fixedly connected to the front side of the middle of the upper and lower ends of the left side wall. The swing control plate 4 is slidably connected to the sliding guide groove 102 in the middle of the right outer wall of the desulfurization tower body 1. The sliding protrusion 401 is slidably connected to the guide arc groove 10201 opened in the sliding guide groove 102. Therefore, the sliding of the sliding protrusion 401 and the guide arc groove 10201 can restrict the swing control plate 4 to move only along the preset trajectory of the guide arc groove 10201, avoid the swing control plate 4 from shifting back and forth or getting stuck during the sliding process, ensure that the swing control plate 4 accurately controls the swing angle of the swing flushing rod 3, and thus ensure that the flushing range of the flushing spray head 301 always fits the blade surface, and there is no problem of missed washing caused by flushing offset.

[0032] The swing control plate 4 has symmetrically and equidistantly installed connecting columns 402 on its right side wall. The connecting columns 402 are slidably connected to the swing groove 303 opened in the right end control arm 302 of the swing flushing rod 3. The rear end of the swing control plate 4 has a longitudinal reciprocating groove 403. Therefore, the sliding engagement of the connecting columns 402 in the swing groove 303 can convert the linear reciprocating motion of the swing control plate 4 into the circular swing motion of the swing flushing rod 3, realizing the power conversion of "linear drive - circular swing". There is no need to set up a complex transmission gear structure, which simplifies the overall structure of the device. The reciprocating groove 403 provides installation and movement space for the drive components of the subsequent drive motor 5, ensuring that the drive power can be stably transmitted to the swing control plate 4, providing a power basis for the continuous swing of the swing flushing rod 3.

[0033] The drive motor 5 has a drive disk 501 fixedly connected to the left end of its drive shaft. A drive lever 502 is eccentrically mounted on the left side wall of the drive disk 501. The drive lever 502 is slidably connected in the reciprocating groove 403 at the rear end of the swing control plate 4. Therefore, when the drive motor 5 drives the drive disk 501 to rotate, the eccentrically mounted drive lever 502 will move along the circumferential trajectory of the drive disk 501 and push the swing control plate 4 to make regular longitudinal reciprocating motion by sliding in the reciprocating groove 403. This will drive the swing rinsing rod 3 to achieve automatic and uniform swing rinsing. This structure realizes the swing of the rinsing rod through a simple eccentric drive method, eliminating the need for manual adjustment of the rinsing angle and improving the automation level of the device. At the same time, the sliding cooperation between the drive lever 502 and the reciprocating groove 403 can buffer the impact force during the drive process, reduce component wear, and extend the service life of the device.

[0034] Using the above technical solution, the swing flushing rod 3, through the trapezoidal flushing spray heads 301 arranged differently on the upper and lower sides, achieves a clean flushing effect on the entire surface of the demister blades without blind spots. The control arm 302 and the swing slide 303 work together to ensure coordinated movement of the upper and lower flushing rods. The swing control plate 4, with the cooperation of the sliding protrusion 401 and the guide arc groove 10201, ensures accurate movement trajectory. The "linear-circular" power conversion is achieved through the adaptation of the connecting column 402 and the swing slide 303, simplifying the structure and ensuring stable power transmission. The drive motor 5, through the eccentrically driven drive disc 501 and drive lever 502, drives the swing control plate 4 to reciprocate regularly, thereby realizing the automatic uniform swing of the swing flushing rod 3, improving the degree of automation and buffering the impact to reduce wear and extend service life. All components work together to form a complete automated flushing system from "power drive - motion control - flushing coverage", ensuring accurate and efficient flushing, reducing manual intervention, and further improving the operational stability and durability of the demister.

[0035] The gas-liquid common pipe 6 and the left end connection of each swing flushing rod 3 are provided with an inverted conical sliding adapter 601. Both the left and right ends of the sliding adapter 601 are fitted with sealing gaskets 602. Both the front and rear ends of the gas-liquid common pipe 6 are equipped with electromagnetic control valves 7.

[0036] Using the above technical solution, the inverted conical sliding adapter 601 can maintain the connection between the gas-liquid common pipe 6 and the internal water passage of the swing flushing rod 3 during the swinging process of the swing flushing rod 3, without affecting the swinging action of the swing flushing rod 3. At the same time, the inverted conical structure can enhance the sealing performance at the joint, and the sealing gasket 602 can further prevent the flushing water from leaking at the joint, avoiding water waste and corrosion of the outer wall of the desulfurization tower body 1 caused by water leakage. When the electromagnetic control valve 7 on the rear side of the gas-liquid common pipe 6 is opened, the electromagnetic control valve on the front side... When valve 7 is closed, external equipment injects liquid into the gas-liquid common pipe 6, which then sprays the rinsing nozzle 301 of the swing rinsing rod 3 onto the blades of the demister body 2. When the electromagnetic control valve 7 on the rear side of the gas-liquid common pipe 6 is closed and the electromagnetic control valve 7 on the front side is open, external equipment injects air into the gas-liquid common pipe 6, so that the rinsing nozzle 301 of the swing rinsing rod 3 blows high-pressure airflow onto the blades of the demister body 2 to dry the blades of the demister body 2 and prevent dirt from adhering.

[0037] The specific usage and function of this embodiment: In this utility model, the flue gas containing mist rises from the bottom of the desulfurization tower and flows through the demister body 2. The trapezoidal blades with a central convex shape optimize the flue gas flow path, and the curved bends prevent slurry residue from remaining at the bends. The guide protrusions 201 accelerate the dripping of condensate and accumulated liquid. The mist droplets are captured and separated under the action of the blades, achieving efficient demisting. When it is necessary to rinse and prevent scale from the blades of the demister body 2, the drive motor 5 is started. The drive motor 5 drives the drive disc 501 to rotate, and the eccentrically mounted drive lever 502 slides in the reciprocating groove 403 of the swing control plate 4, pushing the swing control plate 4 to make regular longitudinal reciprocating motion along the sliding guide groove 102 and guide arc groove 10201 of the desulfurization tower body 1. The swing control plate 4 is controlled by the swing rinsing rod 3 through the connecting column 402. The arm 302 slides within the swing groove 303, converting the linear reciprocating motion into the circular swing of the swing flushing rod 3. At this time, the solenoid control valve 7 on the rear side of the gas-liquid common pipe 6 is opened and the solenoid control valve 7 on the front side is closed. External high-pressure water enters the swing flushing rod 3 through the gas-liquid common pipe 6 and the inverted conical sliding adapter 601 (keeping the water path connected and sealed during swing). The trapezoidal flushing spray heads 301 arranged differently on the upper and lower sides flush the entire surface of the blade without blind spots. After flushing, the solenoid control valve 7 on the rear side of the gas-liquid common pipe 6 is closed and the solenoid control valve 7 on the front side is opened. The external high-pressure air source is delivered to the flushing spray head 301 through the same passage, blowing high-pressure airflow onto the blade to dry it and prevent residual moisture from causing dirt to adhere. Throughout the process, the protective side plate 8 protects the outer transmission components and ensures the stable operation of the device.
