Description

Technical Field

[0001] This application relates to the field of dust removal, and in particular to a submersible dual-channel high-efficiency wet scrubber. Background Technology

[0002] In industrial production processes such as metallurgy, chemical industry, and building materials, especially in high-heat processes such as ironmaking, steelmaking, and sintering, large amounts of flue gas containing high-temperature, high-humidity, and highly viscous dust mixed with steam are often emitted. This type of flue gas has a complex composition, and the dust particles, after combining with water vapor, have strong adhesion and are prone to accumulate inside the dust removal equipment, leading to increased system resistance, high operating energy consumption, and seriously affecting dust removal efficiency and long-term stable operation of the equipment. Although wet dust removal technology is widely used in such working conditions, it still faces many technical bottlenecks in the treatment of high-humidity and high-viscosity flue gas.

[0003] Traditional wet dust collection equipment, such as impact dust collectors, spray towers, and submersible dust collectors, generally suffer from short gas-liquid contact time and limited dust collection efficiency when dealing with dusty gases containing steam. Dust particles are difficult to be fully wetted and captured in a short time, making it difficult to meet increasingly stringent ultra-low emission standards.

[0004] Immersion dust removal technology directly introduces dust-laden gas into the liquid submersible and uses the intense mixing of the gas and liquid phases to capture dust, theoretically resulting in higher dust removal efficiency. However, traditional immersion structures generally suffer from high airflow resistance and high energy consumption. Because their designs often employ a single flow channel or a simple multi-pipe arrangement, the airflow path under the liquid is singular and the turning point is sudden, leading to a significant increase in system pressure loss, insufficient gas-liquid contact, short washing time, and reduced dust removal efficiency. Summary of the Invention

[0005] The purpose of this application is to address the shortcomings of traditional submerged structures mentioned in the background art, such as high airflow resistance and high energy consumption. Because their designs often employ single-channel or simple multi-pipe arrangements, the airflow has a single path and sudden turning point under the liquid, resulting in a significant increase in system pressure loss, insufficient gas-liquid contact, short washing time, and reduced dust removal efficiency. This application provides a submerged dual-channel high-efficiency wet scrubber.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: A submersible dual-channel high-efficiency wet scrubber includes a dust collection chamber. An air inlet pipe is fixed to one side of the dust collection chamber, an air outlet pipe is fixed to the top of the dust collection chamber, and a sedimentation tank is fixed to the bottom of the dust collection chamber. The dust collection chamber, air outlet pipe, and sedimentation tank are all interconnected. Several rectangular guide pipes arranged in a trapezoidal pattern are fixed inside the dust collection chamber and are connected to the air inlet pipe. Several water bath pipes arranged in a matrix are fixed to the bottom of the guide pipes and are connected to the guide pipes. An air distribution head is fixed to the end of each water bath pipe away from the guide pipe. The air distribution head is frustum-shaped and has several circumferentially distributed air distribution holes on its surface facing the water bath pipe. Several water bath pipes are arranged in adjacent rows, alternating vertically. An anti-clogging mechanism is provided between the guide pipe and the water bath pipes. An auxiliary cleaning mechanism is provided inside each water bath pipe. A centrifugal dehydrator is installed between the air outlet pipe and the dust collection chamber.

[0007] By adopting the above technical solution, the combination of the guide pipe and the matrix-style staggered water bath pipe, along with the oscillating atomization formed by the frustum-shaped air distribution head, and the anti-clogging mechanism preventing blockage between the water bath pipe and the guide pipe, while the anti-clogging mechanism drives the auxiliary cleaning mechanism to further clean the inner wall of the water bath pipe, the airflow distribution is optimized and the washing time is extended. Combined with the dual-channel design of the guide pipe and the water bath pipe, the system resistance is significantly reduced while ensuring dust removal efficiency. This allows the dust collector to stably achieve the ultra-low emission standard of ≤5mg / m³ even under high humidity and high viscosity dust conditions, and the system resistance is only half that of the traditional design, which greatly reduces operating energy consumption and reduces the blockage of the water bath pipe, minimizing the impact on normal dust removal work.

[0008] Furthermore, the anti-clogging mechanism includes several anti-clogging heads disposed within the guide pipe. Each anti-clogging head is cylindrical and corresponds one-to-one with a water bath pipe. Limiting rods are fixed on both sides of each anti-clogging head. The limiting rods facing the anti-clogging head are arc-shaped and slide against the side wall of the anti-clogging head. Two limiting rods are fixedly connected to the guide pipe, and a connecting ring is fixed between the two limiting rods. A staggered synchronization component is provided between the several anti-clogging heads and the guide pipe. The staggered synchronization component can ensure that multiple anti-clogging heads operate in sequence, avoiding simultaneous blockage of all water bath pipes. A synchronous drive component is provided on one side of the guide pipe.

[0009] By adopting the above technical solution, the periodic lifting and lowering movement of the anti-clogging head in the guide pipe can mechanically clean the lower area of ​​the guide pipe, thereby effectively preventing high-humidity dust from adhering and accumulating between the guide pipe and the water bath pipe, and maintaining the smooth flow of air.

[0010] Furthermore, the misalignment synchronization component includes several reciprocating rods disposed inside the guide tube. Each of the reciprocating rods corresponds to an anti-clogging head and is fixedly connected. A connecting rod is rotatably connected to the end of each reciprocating rod away from the anti-clogging head. Two symmetrical rotating wheels are eccentrically rotatably connected to the end of each connecting rod away from the reciprocating rod. A connecting shaft is fixed between the rotating wheels of adjacent anti-clogging heads. The connecting shaft on the rotating wheel near the inner wall of the guide tube is rotatably connected to the guide tube.

[0011] By adopting the above technical solution, the rotating wheel converts the rotational motion into the linear reciprocating motion of the anti-clogging head, and the phase difference design forms a wave-like cleaning action, so that the anti-clogging head moves in sequence according to a preset order. While continuously cleaning, the airflow channel is kept partially open at all times, avoiding excessive system pressure fluctuations and ensuring a continuous and stable dust removal process.

[0012] Furthermore, the synchronous drive assembly includes a drive shaft disposed inside the guide tube, the two ends of the drive shaft being rotatably connected to the inner wall of the guide tube, a plurality of circumferentially distributed fan blades being fixed on the drive shaft, and a transmission component being disposed between the drive shaft and a plurality of connecting shafts corresponding to the guide tube.

[0013] By adopting the above technical solution, when the dust-laden steam flow passes through the main channel, it will impact these fan blades, thereby directly driving the drive shaft to rotate. The drive shaft drives the transmission components, which then transmit the rotational power to the corresponding connecting shafts.

[0014] Furthermore, the transmission component includes a plurality of transmission gears disposed on one side of the corresponding guide tube, one end of the drive shaft passes through the guide tube and is fixedly connected to the corresponding transmission gear, a connecting shaft inside the guide tube near the inner wall of the guide tube passes through the guide tube and is fixedly connected to the corresponding transmission gear, and a transmission chain is connected between the plurality of transmission gears.

[0015] By adopting the above technical solution, when the drive shaft rotates, it drives the corresponding transmission gear, which in turn drives the transmission chain, which in turn drives the remaining transmission gears to rotate, thereby ensuring the synchronicity and reliability of the long-term operation of several anti-blocking heads.

[0016] Furthermore, two symmetrical support rods are provided between adjacent transmission gears, the transmission chain is located between the two support rods, one end of the support rod is fixedly connected to the guide pipe, and a limit wheel is rotatably connected to the support rod, the limit wheel abutting against the transmission chain.

[0017] By adopting the above technical solution, the transmission chain is limited by the limiting wheel on the support rod, thereby reducing the possibility of the transmission chain disengaging from the transmission gear.

[0018] Furthermore, the auxiliary cleaning mechanism includes a rotating rod disposed inside a water bath pipe. An annular groove corresponding to the rotating rod is formed on the inner wall of the water bath pipe. Both ends of the rotating rod are in the annular groove and are rotatably connected to the water bath pipe. A cleaning rod is fixed on the rotating rod. The cleaning rod is the same length as the water bath pipe and abuts against the inner wall of the water bath pipe. A rotating component is provided on the rotating rod.

[0019] By adopting the above technical solution, the rotating rod rotates in the water bath tube, and the rotating rod drives the cleaning rod, which in turn causes the scraper on the cleaning rod to rotate along the inner wall of the water bath tube, thereby achieving online self-cleaning of the inside of the water bath tube and preventing the increase in resistance and uneven flow caused by the reduction in pipe diameter.

[0020] Furthermore, the rotating assembly includes a threaded ring fixed in the middle of the rotating rod, a threaded rod threadedly connected to the threaded ring, and a transverse guide rod fixed at one end of the threaded rod near the anti-clogging head, the two ends of the guide rod being linearly slidably connected to the inner wall of the water bath pipe.

[0021] By adopting the above technical solution, the anti-blocking head presses down on the threaded rod during its reciprocating motion, allowing the threaded rod to move linearly under the restriction of the guide rod. During the pressing down of the threaded rod, the threaded ring is driven to rotate, thereby converting the reciprocating motion of the anti-blocking head into the power for the rotation of the rotating rod.

[0022] Furthermore, a return spring is fitted at the end of the threaded rod away from the anti-blocking head. One end of the return spring is fixedly connected to the threaded rod. An abutment ring is fitted on the threaded rod. The other end of the return spring is fixedly connected to the abutment ring. The abutment ring is rotatably connected to the rotating rod.

[0023] By adopting the above technical solution, when the anti-blocking head is far away from the threaded rod, the return spring automatically returns to its original position after the threaded rod is no longer under force, thus facilitating the reset of the threaded rod and making it easier to repeat the extrusion next time.

[0024] In summary, this application includes at least one of the following beneficial effects; 1. This application, by adopting a combination design of trapezoidal distribution guide pipes and matrix-style staggered water bath pipes, and with the upward-facing frustum-shaped air distribution head, allows the dust-laden airflow to undergo an impact-turning-scattering process underwater, and agitates an oscillating atomization array on the water surface. This significantly extends the effective gas-liquid contact and washing time, ensuring efficient collection of high-humidity, sticky dust while reducing the inherent airflow resistance of the submersible structure by more than 50%. It achieves a balance between high-efficiency purification and low operating energy consumption from the source, solving the problem that traditional equipment cannot balance efficiency and energy consumption under such working conditions.

[0025] 2. This application, by placing anti-clogging heads inside the guide pipe and corresponding to each water bath pipe inlet, and using arc-shaped limiting rods on both sides for guidance, combined with a staggered synchronous component, allows multiple anti-clogging heads to rise and fall in sequence, forming a wave-like mechanical unblocking effect. This achieves the goal of continuously scraping away sticky dust and scale that may accumulate at the connection between the guide pipe and the water bath pipe online, effectively preventing channel blockage under high humidity and high sticky dust conditions, and significantly reducing system operating resistance and the frequency of unblocking and maintenance.

[0026] 3. This application, by setting an auxiliary cleaning mechanism consisting of a threaded rod, a threaded ring and a rotating rod in conjunction with the anti-clogging head, transforms the linear reciprocating motion of the anti-clogging head into the rotating scraping motion of the cleaning rod inside the water bath pipe, thereby achieving synchronous online cleaning of the inner wall of the water bath pipe, forming a dual guarantee mechanism of pipe opening anti-clogging and pipe internal scale removal, and further improving the overall anti-clogging efficiency and long-term operational stability.

[0029] The following is in conjunction with the appendix Figure 1 —5 provides further details regarding this application.

[0030] This application discloses an immersion dual-channel high-efficiency wet dust collector.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The submersible dual-channel high-efficiency wet scrubber includes a dust collection chamber 1. An air inlet pipe 2 is fixed to one side of the dust collection chamber 1, an air outlet pipe 3 is fixed to the top of the dust collection chamber 1, and a sedimentation tank 9 is fixed to the bottom of the dust collection chamber 1. The dust collection chamber 1, air outlet pipe 3, and sedimentation tank 9 are all interconnected. Several rectangular guide pipes 4 arranged in a trapezoidal pattern are fixed inside the dust collection chamber 1. The guide pipes 4 are connected to the air inlet pipe 2, and several water bath pipes arranged in a matrix are fixed to the bottom of the guide pipes 4. 5. The water bath pipe 5 is connected to the guide pipe 4. An air distribution head 6 is fixed at the end of the water bath pipe 5 away from the guide pipe 4. The air distribution head 6 is shaped like a frustum and has several circumferentially distributed air distribution holes on the surface facing the water bath pipe 5. Several water bath pipes 5 are arranged in adjacent rows, alternating vertically. An anti-clogging mechanism 7 is provided between the guide pipe 4 and several water bath pipes 5. An auxiliary cleaning mechanism 8 is provided inside the water bath pipe 5. A centrifugal dehydrator 10 is installed between the air outlet pipe 3 and the dust removal chamber 1. The air inlet duct 2 is connected to the smelting process exhaust system, through which a mixed gas containing steam and dust enters. The guide pipes 4 arranged in a trapezoidal pattern within the dust removal chamber 1 ensure uniform airflow distribution before entering the water bath pipes 5. The mixed gas entering the air inlet duct 2 then flows into the guide pipes 4. The water bath pipes 5 are arranged in a matrix, with adjacent columns staggered vertically. Each water bath pipe 5 has a frustum-shaped air distribution head 6 at its end, and several circumferentially distributed air distribution holes, approximately 10mm in diameter, are opened on the surface facing the water. Each air distribution head 6 has 12-16 holes, ensuring even distribution of the gas... The airflow passes through the air distribution head 6 and is then ejected from the air distribution holes. As the airflow is ejected upwards from underwater, it forms an oscillating atomizing array on the water surface, simultaneously reducing water resistance. The specially designed matrix water bath tube 5, compared to the original high-resistance characteristics, produces less than half the original immersion resistance. Furthermore, the underwater structure of the water bath tube matrix 5 is designed with different immersion depths, and the underwater section employs a reverse flow design, causing the guiding airflow to reverse direction and flow upwards within this structure. The airflow will oscillate on the water surface, forming an atomizing array. Additionally, based on the fluid structure, the water bath tube 5 extends into the water... A portion of the side has a uniformly distributed porous structure with a diameter of approximately 6mm, which can enhance the atomization effect of the existing structure by about 30%, thereby extending the effective washing time. An anti-clogging mechanism 7 is installed at the connection between the guide pipe 4 and the water bath pipe 5. An auxiliary cleaning mechanism 8 is installed inside the water bath pipe 5. The centrifugal dehydrator 10 installed before the air outlet pipe 3 adopts a special plate structure, which can achieve efficient gas-water separation. When the mixed gas enters the guide pipe 4, it will drive the anti-clogging mechanism 7, which will unclog the blockage area at the opening of the water bath pipe 5. At the same time, the anti-clogging mechanism 7 will drive the auxiliary cleaning mechanism 8. The cleaning mechanism 8 cleans the inner wall of the water bath pipe 5. Through the combination of the trapezoidal guide pipe 4 and the matrix-style staggered water bath pipe 5, and the oscillating atomization formed by the frustum-shaped air distribution head 6, the airflow distribution is optimized and the washing time is extended. Combined with the dual-channel design of the guide pipe 4 and the water bath pipe 5, the system resistance is significantly reduced while ensuring dust removal efficiency. This allows the dust collector to stably achieve the ultra-low emission standard of ≤5mg / m³ even under high humidity and high viscosity dust conditions, and the system resistance is only half that of the traditional design, which greatly reduces the operating energy consumption. Reference Figure 2 , Figure 3 and Figure 4The anti-blocking mechanism 7 includes several anti-blocking heads 71 ​​disposed inside the guide pipe 4. The anti-blocking heads 71 ​​are cylindrical, and each anti-blocking head 71 corresponds to a water bath pipe 5. Limiting rods 72 are fixed on both sides of the anti-blocking head 71. The limiting rods 72 facing the anti-blocking head 71 are arc-shaped and slide against the side wall of the anti-blocking head 71. The two limiting rods 72 are fixedly connected to the guide pipe 4, and a connecting ring 73 is fixed between the two limiting rods 72. A staggered synchronization component 74 is provided between the several anti-blocking heads 71 ​​and the guide pipe 4. The staggered synchronization component 74 can ensure that the multiple anti-blocking heads 71 ​​act in sequence to avoid blocking all water bath pipes 5 at the same time. A synchronous drive component 75 is provided on one side of the guide pipe 4. The anti-clogging head 71, limiting rod 72, and connecting ring 73 can be made of engineering plastics with self-lubricating and high wear resistance, such as polyoxymethylene or nylon. The anti-clogging head 71 is designed with a hollow structure to reduce its weight. The arc-shaped surface of the limiting rod 72 that contacts the anti-clogging head 71 can be embedded with a polytetrafluoroethylene gasket, thereby forming a sliding pair with a very low coefficient of friction. The synchronous drive component 75 drives the misaligned synchronous component 74, which drives the anti-clogging head 71 to perform periodic up and down movements within the guide tube 4. The misaligned synchronous component 74 can ensure that multiple anti-clogging heads 71 ​​operate in sequence, avoiding simultaneous blockage of all water bath tubes 5. Through the periodic up and down movement of the anti-clogging head 71 within the guide tube 4, mechanical cleaning can be performed on the lower area of ​​the guide tube 4. The arc-shaped design of the limiting rod 72 can ensure the smooth movement of the anti-clogging head 71. The misaligned movement can avoid instantaneous interruption of airflow, thereby effectively preventing the adhesion and accumulation of high-humidity dust between the guide tube 4 and the water bath tube 5, and maintaining the unobstructed airflow channel. Reference Figure 2 , Figure 3 and Figure 4 The misalignment synchronization component 74 includes several reciprocating rods 741 disposed inside the guide tube 4. Each reciprocating rod 741 corresponds to an anti-blocking head 71 and is fixedly connected. A connecting rod 742 is rotatably connected to the end of the reciprocating rod 741 away from the anti-blocking head 71. Two symmetrical rotating wheels 743 are eccentrically rotatably connected to the end of the connecting rod 742 away from the reciprocating rod 741. A connecting shaft 744 is fixed between the rotating wheels 743 between adjacent anti-blocking heads 71. The connecting shaft 744 on the rotating wheel 743 near the inner wall of the guide tube 4 is rotatably connected to the guide tube 4. The rotating wheel 743, connecting rod 742, and connecting shaft 744 can be injection molded from high-strength nylon. This material is high-strength, lightweight, and fatigue-resistant. With the reduced weight of the rotating wheel 743, the torque required for its start-stop and speed change is significantly reduced. When the rotating wheel 743 rotates, it drives the connecting rod 742, which in turn drives the reciprocating rod 741. The reciprocating rod 741 then drives the anti-clogging head 71, which is positioned between the two limit rods 72. This converts the rotational motion into the linear reciprocating motion of the anti-clogging head 71. The connecting shaft 744 enables the mechanical linkage of multiple anti-clogging heads 71. The phase difference design creates a wave-like cleaning action. By converting the rotational motion of the rotating wheel 743 into the linear reciprocating motion of the anti-clogging head 71, and by enabling the mechanical linkage of multiple anti-clogging heads 71, the phase difference design creates a wave-like cleaning action. This allows the anti-clogging heads 71 ​​to operate sequentially in a preset order. While continuously cleaning, the airflow channel remains partially open, preventing excessive system pressure fluctuations and ensuring a continuous and stable dust removal process. Reference Figure 2 , Figure 3 and Figure 4 The synchronous drive assembly 75 includes a drive shaft 751 disposed in the guide tube 4. Both ends of the drive shaft 751 are rotatably connected to the inner wall of the guide tube 4. Several circumferentially distributed fan blades 752 are fixed on the drive shaft 751. A transmission component 753 is disposed between the drive shaft 751 and several rows of connecting shafts 744 in the corresponding guide tube 4. The two ends of the drive shaft 751 are rotatably connected to the side wall of the guide pipe 4 through sealed bearings. When the dust-laden steam flow passes through the main channel, it will impact these fan blades 752, thereby directly driving the drive shaft 751 to rotate. The drive shaft 751 drives the transmission component 753, which transmits the rotational power to the corresponding connecting shafts 744, thereby driving the entire misaligned synchronization assembly 74 to work. By integrating circumferentially distributed fan blades 752 on the drive shaft 751, the kinetic energy of the exhaust gas flowing through the dust collector is creatively recovered and converted into mechanical energy, providing in-situ, adaptive driving power for the anti-clogging mechanism. This eliminates the need for an external motor, achieves "zero power consumption" of the drive system, and greatly simplifies the control system and external circuit configuration. Reference Figure 2 and Figure 4 The transmission component 753 includes a plurality of transmission gears 7531 disposed on one side of the corresponding guide tube 4. One end of the drive shaft 751 passes through the guide tube 4 and is fixedly connected to the corresponding transmission gear 7531. A connecting shaft 744, located near the inner wall of the guide tube 4, passes through the guide tube 4 and is fixedly connected to the corresponding transmission gear 7531. A transmission chain 7532 is connected between the plurality of transmission gears 7531. The transmission gear 7531 can be made of MC nylon, which has good mechanical strength, self-lubrication and noise reduction effect. The transmission chain 7532 can be made of engineering plastic chain. When the drive shaft 751 rotates, it drives the corresponding transmission gear 7531. The transmission gear 7531 drives the transmission chain 7532. The transmission chain 7532 drives the remaining transmission gears 7531 to rotate. Then the transmission gear 7531 drives the corresponding connecting shaft 744, which in turn drives the corresponding rotating wheel 743 to rotate. By using the transmission gear 7531 and the transmission chain 7532, the synchronous rotation of multiple connecting shafts 744 is achieved, thereby ensuring the synchronicity and reliability of the long-term operation of several anti-blocking heads 71. Reference Figure 2 and Figure 4 Two symmetrical support rods 7533 are provided between adjacent transmission gears 7531. The transmission chain 7532 is located between the two support rods 7533. One end of the support rod 7533 is fixedly connected to the guide pipe 4. A limit wheel 7534 is rotatably connected to the support rod 7533. The limit wheel 7534 abuts against the transmission chain 7532. The transmission chain 7532 is limited by the limiting wheel 7534 on the support rod 7533. When the transmission chain 7532 is driven, the transmission chain 7532 drives the limiting wheel 7534 to rotate. By using the limiting wheel 7534 on the support rod 7533 to limit the transmission chain 7532, the possibility of the transmission chain 7532 disengaging from the transmission gear 7531 can be reduced. Reference Figure 3 , Figure 4 and Figure 5 The auxiliary cleaning mechanism 8 includes a rotating rod 82 disposed inside the water bath pipe 5. The inner wall of the water bath pipe 5 has an annular groove corresponding to the rotating rod 82. Both ends of the rotating rod 82 are in the annular groove and are rotatably connected to the water bath pipe 5. A cleaning rod 81 is fixed on the rotating rod 82. The cleaning rod 81 is the same length as the water bath pipe 5 and abuts against the inner wall of the water bath pipe 5. A rotating component 83 is disposed on the rotating rod 82. The rotating rod 82 can be made of glass fiber reinforced nylon rod, and the main body of the cleaning rod 81 can be made of PP plastic. A scraper is fixed on the cleaning rod 81, and the scraper that contacts the inner wall of the water bath tube 5 can be made of flexible TPU. When the anti-clogging head 71 is squeezed into the water bath tube 5, the anti-clogging head 71 squeezes the rotating component 83. The rotating component 83 drives the rotating rod 82, causing the rotating rod 82 to rotate in the water bath tube 5. The rotating rod 82 drives the cleaning rod 81, causing the scraper on the cleaning rod 81 to rotate along the inner wall of the water bath tube 5, so that the mixture adhering to the inner wall of the water bath tube 5 is removed. By rotating the cleaning rod 81 along the inner wall of the water bath tube 5 driven by the rotating rod 82, the sludge or scale adhering to the tube wall can be effectively removed. The annular groove design allows rotation while restricting axial movement, thereby achieving online self-cleaning of the inside of the water bath tube 5 and preventing the increase in resistance and uneven flow caused by the reduction of the tube diameter. Reference Figure 3 , Figure 4 and Figure 5 The rotating assembly 83 includes a threaded ring 832 fixed in the middle of the rotating rod 82. A threaded rod 831 is threadedly connected to the threaded ring 832. A transverse guide rod 833 is fixed at one end of the threaded rod 831 near the anti-blocking head 71. Both ends of the guide rod 833 are linearly slidably connected to the inner wall of the water bath pipe 5. The end of the threaded rod 831 is connected to a transverse guide rod 833. The guide rod 833 is linearly slidably connected to the inner wall of the water bath pipe 5. When the anti-clogging head 71 reciprocates, it presses down on the threaded rod 831, allowing the threaded rod 831 to move linearly under the restriction of the guide rod 833. During the pressing down process, the threaded rod 831 drives the threaded ring 832 to rotate, and the threaded ring 832 drives the rotating rod 82 to rotate. Through the reciprocating motion of the anti-clogging head 71, the threaded rod 831 is pushed to move axially. The threaded pair converts the linear motion into the rotation of the rotating rod 82. The transverse guide rod 833 ensures the stability of the movement trajectory of the threaded rod 831, thereby transmitting the power of the anti-clogging mechanism 7 to the auxiliary cleaning mechanism 8, realizing the linkage effect of one-point drive and two-point cleaning, improving energy utilization, and further reducing the possibility of blockage in the water bath pipe 5. Reference Figure 3 , Figure 4 and Figure 5 A return spring 834 is fitted at the end of the threaded rod 831 away from the anti-blocking head 71. One end of the return spring 834 is fixedly connected to the threaded rod 831. An abutment ring 835 is fitted on the threaded rod 831. The other end of the return spring 834 is fixedly connected to the abutment ring 835. The abutment ring 835 is rotatably connected to the rotating rod 82. When the threaded rod 831 moves under pressure, it drives the return spring 834, which stretches. When the anti-blocking head 71 moves away from the threaded rod 831, the return spring 834 automatically returns to its original position after the threaded rod 831 is no longer under pressure. The contact ring 835 connects one end of the return spring 834 to the rotating rod 82, so that the return spring 834 can limit the rotation of the rotating rod 82 without hindering its rotation. By using the return spring 834 to limit one end of the threaded rod 831, the threaded rod 831 can be easily reset, facilitating the next repeated pressing. Working principle: When this dust collector is working, the dust-laden steam mixture from the smelting process enters the dust collection chamber 1 through the external pressurized air inlet pipe 2. The gas first enters the rectangular guide pipe 4 with a trapezoidal distribution to achieve preliminary distribution and uniform flow of the airflow. Subsequently, the airflow is diverted to the matrix-arranged water bath pipes 5 below. Inside the water bath pipes 5, the airflow is forced to change direction and is ejected from the upward opening of the frustum-shaped air distribution head 6. This process causes the gas to impact the water at high speed, which not only completes the efficient immersion water bath washing and removes most of the dust, but also agitates the water surface with violent oscillations, forming a stable atomization zone, which greatly prolongs the gas-liquid contact and reaction time, and achieves deep purification of the dust. Meanwhile, the high-speed airflow flowing through the guide pipe 4 drives the fan blades 752 on its internal drive shaft 751 to rotate, directly converting the kinetic energy of the exhaust gas into mechanical energy. The drive shaft 751 transmits the rotational motion synchronously to the connecting shaft 744 of all the misaligned synchronization components 74 through the external transmission gear 7531 and chain. The connecting shaft 744 drives the eccentric rotating wheel 743 to rotate, and through the connecting rod 742 and the reciprocating rod 741, the rotational motion of the rotating wheel 743 is converted into the periodic up-and-down linear motion of the anti-clogging head 71 in the guide pipe 4. Multiple anti-clogging heads 71 ​​act sequentially according to the phase difference, forming a wave-like mechanical cleaning, continuously scraping away the guide gas. To prevent the accumulation of sticky dust in the area where the lower end of pipe 4 connects to the water bath pipe 5, and to keep the air passage clear, during the descent of the anti-clogging head 71, its bottom simultaneously presses down on the threaded rod 831 extending into the upper end of the water bath pipe 5. The threaded rod 831 moves straight down under the limit of the transverse guide rod 833, driving the threaded ring 832 that meshes with it to rotate, thereby causing the rotating rod 82 and the cleaning rod 81 fixed thereon to rotate inside the water bath pipe 5. The flexible scraper on the edge of the cleaning rod 81 scrapes the inner wall of the water bath pipe 5 to remove the attached dirt. When the anti-clogging head 71 rises, the return spring 834 pushes the threaded rod 831 to automatically return to its original position, preparing for the next cleaning cycle. After thorough washing and purification, the gas rises and enters the centrifugal dehydrator 10 at the top. Inside the dehydrator, residual moisture and fine droplets in the gas are efficiently separated under centrifugal force. Finally, the dried and clean gas is discharged through the exhaust pipe 3 in compliance with standards, while the mud and water generated during washing settle into the sedimentation tank 9 at the bottom, achieving mud and water separation and recycling.
