Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment, and in particular to a dust collection component for a desulfurization tower. Background Technology

[0002] Desulfurization towers are the core equipment of industrial flue gas desulfurization systems. They remove sulfur dioxide from flue gas through physical absorption or chemical reactions, reducing acid gas emissions. They are key devices for achieving environmental compliance in industries such as thermal power, steel, chemical, and metallurgy. Their design must be matched to operating parameters such as flue gas volume and dust content, with the core objectives of efficient desulfurization, low-energy operation, and stable compliance.

[0003] The production processes in industries such as thermal power, steel, and chemicals differ significantly, resulting in highly complex and volatile flue gas emissions. In terms of flue gas volume, scenarios such as the start-up and shutdown of thermal power units, batch switching in the steel industry, and adjustments to reaction processes in the chemical industry can all cause substantial fluctuations in flue gas emissions, with frequent transitions from low-flow, stable emissions to high-flow, peak emissions. Existing dust collection components mostly employ fixed structural designs, and the angles and layouts of their core components, such as flow guides and interceptors, cannot be adjusted, potentially making them unsuitable for complex and changing operating conditions. Under high flue gas velocity conditions, the limited cross-section of the fixed structure increases flue gas flow resistance, easily leading to airflow congestion and excessive pressure drop. This not only affects the normal operation of subsequent desulfurization towers but may also exacerbate wear and tear on internal components due to airflow impact. Conversely, under low flue gas velocity conditions, the fixed structure cannot extend the flue gas residence time, and dust particles, due to insufficient inertia, are difficult to intercept effectively, resulting in incomplete capture and escape of fine particles. This significantly reduces dust collection efficiency and fails to meet environmental protection requirements. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dust collection component for desulfurization towers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dust collection assembly for a desulfurization tower includes a housing. Rods are rotatably connected to one and the other ends of the housing. Support rods are sleeved on the outer walls of both sets of rods. A motor is mounted on one end of the housing, and a plate is connected to the output end of the motor. Columns are connected to one and the other ends of the plate. A groove is formed at one end of each set of support rods, and the two sets of columns respectively fit into their corresponding grooves. Flanges are connected to one and the other ends of the housing. Guide plates are connected to the outer walls of both sets of rods, and both sets of guide plates are located inside the housing. One end of each set of guide plates is an inclined surface. A baffle is connected to one end of the housing, and the baffle has multiple sets of ventilation holes. An opening is formed at one end of the housing, and both sets of guide plates are located above the opening.

[0007] Preferably, one end of the housing is connected to a second box body, the second box body is hinged to a second door body, and the opening body is connected to the second box body.

[0008] Preferably, one end of the housing is connected to a box body, and one end of the box body is hinged to a door body.

[0009] Preferably, the housing has heat dissipation holes at one end and the other end, and the inner walls of both sets of heat dissipation holes are connected with filter screens.

[0010] Preferably, the housing has a cable inlet hole at one end, and the inner wall of the cable inlet hole is connected to multiple sets of rubber gaskets.

[0011] Preferably, a sealing gasket is adhered at the joint between the second door body and the second box body.

[0012] Preferably, the bottom of the second box body is an inclined surface and the lowest point is the end near the second door body.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through the coordination of the baffle, motor, and support rod, the baffle, located within the housing, features multiple evenly distributed ventilation holes. This design ensures smooth flue gas flow while simultaneously dispersing airflow energy through a rationally divided flow channel cross-section. This buffers the high-speed flue gas as it passes through the ventilation holes, reducing its velocity. Due to inertia, dust particles are less likely to pass quickly with the airflow after the velocity slows down, allowing more particles sufficient time to contact the subsequent interception structure, thus increasing the capture probability. When the flue gas contacts the inclined surface of the guide plate, the airflow direction changes abruptly. Dust particles, due to their inertia, cannot follow the airflow change direction in time and violently impact the guide plate surface. During the impact, the particles adsorb and agglomerate, forming larger dust clouds, preventing fine particles from escaping with the airflow. Simultaneously, the linkage transmission structure composed of the motor, plate, column, trough, and support rod provides the guide plate with an adjustable tilt angle. When the motor drives the plate to rotate, the columns at both ends of the plate move in a circular motion simultaneously. The columns slide and engage with the grooves at the ends of the support rods, thereby pushing the support rods to rotate around their axis, ultimately adjusting the tilt angle of the guide plate. This adjustment function can be tailored to different flue gas conditions: in high flue gas velocities, reducing the tilt angle of the guide plate further optimizes flue gas flow efficiency and prevents airflow congestion; in low flue gas velocities, increasing the tilt angle of the guide plate extends the flow path of the flue gas within the casing, allowing dust particles to fully contact the guide plate. This enables the component to adapt to complex operating conditions with varying flue gas volumes and dust contents in industries such as thermal power, steel, and chemicals, improving the targeting and overall efficiency of dust capture to a certain extent, and providing a cleaner flue gas environment for subsequent desulfurization operations in the desulfurization tower.

[0015] 2. Through the coordinated operation of the baffle plate, housing two, and door two, the dust particles intercepted by the baffle plate collide and agglomerate, forming larger and heavier dust clumps. Under the influence of gravity and the guidance of the inclined surface of the baffle plate, the dust clumps slide down the baffle plate surface and fall directly into the connected housing two through the opening on the housing, achieving centralized collection of dust and preventing dust clumps from adhering and accumulating on the inner wall of the housing. The bottom of housing two features an inclined surface design, utilizing the slope to guide the dust falling into the housing to one side of door two for concentrated accumulation, preventing dust dispersion and residue. Simultaneously, a sealing gasket is adhered at the joint between door two and housing two, filling the gaps and forming a tight seal to prevent collected dust from leaking out, ensuring a clean working environment and stable equipment operation. Subsequent cleaning does not require complex disassembly of the entire dust collection assembly; simply opening the hinged door two allows for easy and efficient cleaning of the accumulated dust. This design shortens the cleaning operation time, reduces equipment downtime for maintenance, lowers production losses caused by downtime, and further improves the overall operating efficiency and practicality of the equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 A dust collection component for a desulfurization tower includes a housing 1. Rods 2 are rotatably connected to one and the other ends of the housing 1. Support rods 3 are sleeved on the outer walls of both sets of rods 2. A motor 4 is installed at one end of the housing 1. The model of the motor 4 can be selected according to actual conditions. A plate 5 is connected to the output end of the motor 4, and the motor 4 drives the plate 5 to rotate. Columns 6 are connected to one and the other ends of the plate 5, and the plate 5 drives the column 6 to rotate. A groove 7 is opened at one end of each set of support rods 3. 6 is respectively attached to the corresponding tank 7. The column 6 slides in the tank 7, thereby driving the support rod 3 to rotate. The rotation of the support rod 3 will drive the rod 2 to rotate. One end of the shell 1 is connected to the other end of the shell 1. One set is used to connect to the gas transmission pipeline, and the other set is used to connect to the gas inlet of the desulfurization tower. The outer walls of both sets of rods 2 are connected to guide plates 18. The guide plates 18 change the airflow direction and use the inertial force of the particles to make them impact the guide plates 18 and agglomerate. The two sets of guide plates 18 Both are located inside the housing 1. One end of each of the two sets of guide plates 18 is inclined to guide the agglomerated dust downwards. One end of the housing 1 is connected to a baffle 19 with multiple ventilation holes 20 to reduce the flow rate. One end of the housing 1 has an opening 21, and both sets of guide plates 18 are located above the opening 21. After the gas enters the housing 1, the flow rate is reduced by the cooperation of the baffle 19 and the ventilation holes 20. After the gas comes into contact with the guide plates 18, the guide plates 18 change the gas flow direction. The inertial force of the particles causes them to collide with the guide plates 18 and agglomerate, thus achieving the purpose of dust collection. At the same time, the motor 4 can be started to drive the plate 5 to rotate. The column 6 and the groove 7 cooperate to drive the support rod 3 to rotate, which in turn drives the rod 2 to rotate. The rotation of the rod 2 drives the guide plate 18 to rotate, adjusting its tilt angle. For example, the angle is reduced to reduce the flow rate when the smoke velocity is high, and the angle is increased to extend the airflow path when the smoke velocity is low, which can improve the smoke and dust capture efficiency to a certain extent.

[0024] In this embodiment, one end of the housing 1 is connected to a second box 15, and the second box 15 is hinged to a second door 16. An opening 21 is connected to the second box 15. Dust intercepted by the guide plate 18 falls into the second box 15 through the opening 21 under the guidance of gravity and the inclined surface of one end of the guide plate 18. Opening the second door 16 allows for cleaning of accumulated dust, improving cleaning efficiency and reducing downtime to some extent. One end of the housing 1 is connected to a first box 8, and one end of the first box 8 is hinged to a first door 9. Opening the first door 9 allows for maintenance of the motor 4. Both ends of the first box 8 have ventilation holes 10 for ventilation and heat dissipation. Filters 11 are connected to the inner walls of both sets of ventilation holes 10 to prevent dust from entering. One end of the first box 8 has a wire inlet hole 13 for threading wires. Multiple rubber gaskets 14 are connected to the inner wall of the wire inlet hole 13 to prevent friction between the cable and the wire inlet hole 13. A sealing gasket 17 is adhered to the joint between door 2 16 and box 2 15 to enhance the seal. The bottom of box 2 15 is sloping, with the lowest point being the end closest to door 2 16, which guides dust to accumulate on one side of door 2 16 for easy cleaning.

[0025] The working principle of this embodiment is as follows: During use, one end of the component is fixedly connected to the industrial flue gas pipeline via flanges 12 at both ends of the housing 1, and the other end is sealed and connected to the desulfurization tower inlet, completing the overall installation and positioning, ensuring that the flue gas can enter the component along the designated path. After the flue gas enters the housing 1, it first flows through the internal baffle 19. The evenly distributed ventilation holes 20 on the baffle 19 ensure smooth flue gas flow while dividing the flow channel and dispersing the airflow energy, causing the high-speed flue gas to form a buffer and reduce its flow velocity, creating conditions for the capture of dust particles. The decelerated flue gas continues to flow and contacts the two sets of guide plates 18. Since one end of the guide plate 18 is an inclined surface, the flue gas flow direction changes abruptly. Due to inertia, the dust particles cannot follow the airflow to change direction quickly, and they collide with the surface of the guide plate 18. The particles adsorb and agglomerate with each other, forming larger dust clumps, preventing fine particles from escaping with the airflow. The motor 4 is started according to the flue gas conditions, such as high flue gas velocity and low flue gas velocity. The output end of the motor 4 drives the plate 5 to rotate, and the columns 6 at both ends of the plate 5 move in a circular motion simultaneously. The columns 6 slide against the groove 7 at the end of the support rod 3, pushing the support rod 3 to rotate around the axis of the rod 2, which in turn drives the guide plate 18 on the outer wall of the rod 2 to adjust the tilt angle. The angle is reduced at high flue gas velocity to optimize the flow efficiency, and the angle is increased at low flue gas velocity to prolong the flue gas residence time and improve the capture targeting. The dust clumps intercepted and agglomerated by the guide plate 18 slide down the surface under the action of gravity and the guidance of the inclined surface of the guide plate 18 to the inlet 21 of the shell 1, and fall into the connected box 15 through the inlet 21. The inclined surface at the bottom of the box 15 guides the dust clumps to the door 16 side to accumulate, and the sealing gasket 17 at the joint between the door 16 and the box 15 can prevent the dust clumps from leaking. After the flue gas has been intercepted, the clean flue gas is transported to the desulfurization tower through the internal flow channel of the casing 1, providing a clean flue gas environment for subsequent desulfurization operations. The internal motor 4 can be inspected and maintained periodically by opening door 9 of casing 8. When cleaning flue gas, simply open door 16 of casing 15 to handle the accumulated dust clumps; the operation is convenient.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
