Description

Technical Field

[0001] This invention relates to the field of wet dust removal technology, specifically a self-cleaning explosion-proof vortex wet dust collector and its method. Background Technology

[0002] Water cyclone wet scrubber is a highly efficient industrial dust removal technology. It mainly captures particulate matter by contacting water with dust-laden gas. Through contact with water droplets, water films, and bubbles, it utilizes mechanisms such as inertial collision, interception, and diffusion to improve dust removal efficiency. It is widely used in industries such as metallurgy, boilers, mining, and building materials. It is particularly suitable for dust removal in steel plants for strip steel, medium and heavy plates, mixing, batching, wire rod, flame cutting, and slag removal. At the same time, the water flow can quickly cool high-temperature particles to prevent sparks from igniting dust and causing an explosion. Existing technology main components such as Figure 3 The diagram shows a dust collector housing, several sets of water-air separators installed inside the dust collector housing, and a water vortex dust removal mechanism installed inside the dust collector housing, with a water injection mechanism installed inside the water vortex dust removal mechanism.

[0003] A wet scrubber relies on the swirling action of water to thoroughly mix dust and water. In the steel rolling process of the metallurgical industry, a large amount of waste gas containing lubricating oil and metal dust is generated. When the wet scrubber is used for dust removal, the dust-laden gas is brought into the scrubber at a certain wind speed. The dust-laden gas first comes into contact with the water curtain generated by the water injection mechanism, causing large particles inside to fall off. Then, it is guided to the vortex of the scrubber mechanism to fully contact the water flow for dust removal. Then, the water flow mixed with dust and oil is discharged from the top of the scrubber mechanism and enters the settling zone at the rear. The purified gas is usually discharged upwards. The low-density oil and fine hydrophobic dust carried in the mixture are prone to accumulate and remain on the surface of the liquid in the settling zone. If these residues are not cleaned in time, they will form an oil film or accumulation layer, affecting the subsequent dust removal effect. At the same time, the continuous flow of mixed liquid into the settling zone will impact the liquid surface. When the impact acts on the liquid surface containing oil and dust residue, it will cause violent disturbance, fluctuation and turbulence. The oil and fine dust that have settled or are suspended near the liquid surface are stirred, broken and emulsified, and resuspended in the water. This weakens the swirling capture effect of the water, and some fine dust cannot be effectively captured and settled. Finally, it escapes from the dust collector with the purified gas, further reducing the dust removal efficiency of the equipment.

[0004] Therefore, the present invention provides a self-cleaning explosion-proof vortex wet dust collector that can promptly clean residual oil and dust and prevent subsequent mixed liquids from impacting the oil and dust and causing them to resuspend in the water. Summary of the Invention

[0005] To address the problem in existing technologies that make it difficult to promptly clean oil and dust suspended in the settling zone when removing exhaust gas containing lubricating oil and metal dust during steel rolling processes in the metallurgical industry, a self-cleaning explosion-proof vortex wet dust collector and its method have been designed.

[0006] The technical solution adopted by this invention to solve its technical problem is: a self-cleaning explosion-proof vortex wet dust collector and its method, including a dust collector housing and a water vortex dust removal mechanism installed inside the dust collector housing. A self-cleaning mechanism is symmetrically arranged at the bottom of the water vortex dust removal mechanism, and a water injection mechanism is fixedly connected inside the water vortex dust removal mechanism. The self-cleaning mechanism includes a rotating component rotatably connected to the dust collector housing, located at the bottom of the water vortex dust removal mechanism, and a cleaning component is drivenly connected to the rotating component. During dust removal, the self-cleaning component draws dust-laden gas into the dust collector housing, causing the water curtain inside the water vortex dust removal mechanism to contact and impact the water surface. The dust-laden gas carries water into the water vortex dust removal mechanism, generating a vortex. The dust-laden gas and water are fully mixed and discharged through one side of the water vortex dust removal mechanism. The water carrying oil and dust flows smoothly into the rear settling area through the self-cleaning mechanism, while clean gas is discharged upwards. Simultaneously, the gas driving the water flow drives the rotating component to rotate, thereby driving the cleaning component to reciprocate and clean the oil and dust in the rear settling area.

[0007] Furthermore, the self-cleaning mechanism also includes a transmission component fixedly connected to one side of the rotating component and a diversion component fixedly connected inside the dust removal box. It guides the water flow carrying oil and dust discharged from one side of the water vortex dust removal mechanism to flow smoothly into the rear settling area. The rotating component drives the cleaning component to rotate through the transmission component.

[0008] Furthermore, the rotating assembly includes a rotating shaft rotatably connected to the dust collection box. Uniformly distributed rotating blades are fixedly connected to the outside of the rotating shaft. The rotating blades are arc-shaped, with their bending direction opposite to the gas flow direction. The end of the rotating blade away from the rotating shaft is scoop-shaped, and a friction block for increasing friction is provided inside. The rotating assembly is located at the bottom of the water cyclone dust collection mechanism. The outside of the rotating blades is not in contact with the bottom of the water cyclone dust collection mechanism. The gas carries the water flow and drives the rotating blades to rotate. The scoop-shaped setting at one end of the rotating blades, in conjunction with the water flow, drives the large dust particles that have settled to the bottom of the cone.

[0009] Furthermore, the cleaning component includes a protective mounting component fixedly connected to the dust collection box and a sliding block slidably installed inside the protective mounting component. A reciprocating screw is fixedly connected to the end of the transmission component away from the rotating component, and its two ends are rotatably connected to the dust collection box. A cleaning component is rotatably connected to the bottom end of the sliding block. A self-locking component is provided at the connection between the rotating component and the cleaning component. Dust collection boxes are symmetrically arranged inside the dust collection box. The cleaning component is located between the water vortex dust removal mechanism and the dust collection box.

[0010] Furthermore, the water vortex dust removal mechanism includes a partition fixedly installed inside the dust removal box and a water vortex generating component fixedly connected to one side of the bottom end of the partition. A buffer guide component is slidably connected inside one side of the partition, which is located at the water discharge end of the water vortex generating component.

[0011] Furthermore, the water vortex generating component includes a diversion plate fixedly connected to one side of the bottom end of the separator, a first baffle fixedly installed inside the dust removal box, and a second baffle fixedly connected to the bottom of one side of the separator, which is located above the first baffle.

[0012] Furthermore, the dust collector is equipped with multiple water-air separators inside, which are located between the water vortex dust removal mechanism and the dust collector. A support frame is fixedly connected to the bottom of the dust collector. The water-air separator is located on the upper end of the cleaning component. The buffer guide component is located on the upper end of the first baffle. The guide component is fixedly connected to the first baffle on the side close to the first baffle.

[0013] Furthermore, the buffer guide assembly includes a guide plate that is slidably connected to the separator, a fixed rod that is slidably installed inside the guide plate, both ends of the fixed rod being fixedly connected to the separator, and springs symmetrically arranged on the outer side of the fixed rod.

[0014] Furthermore, the dust collector includes an air inlet on one side and an exhaust end on the top. The bottom of the dust collector is set as an inverted conical dust collection cone. The interior of the dust collector is divided into two chambers by a water vortex dust removal mechanism in conjunction with water flow. The chamber inside the separator is the air inlet chamber, and the chamber between the separator and the dust collection box is the exhaust chamber.

[0015] The beneficial effects of this invention are: (1) The self-cleaning explosion-proof vortex wet dust collector and method of the present invention use a fan to draw dust-laden gas into the dust collector box and make it impact the water surface at a certain speed, and drive the water flow into the water vortex generator to generate vortex separation of oil and dust. The water flow carrying oil and dust is discharged through the upper end of the first baffle, and the water flow is smoothly flowed into the rear settling area through the cooperation of the buffer guide component and the guide component, so as to avoid the water flow directly spraying out and contacting the liquid surface to generate violent disturbance and fluctuation, thereby breaking the original relatively stable oil and dust layer on the liquid surface, causing some oil and fine dust to be resuspended in the liquid, resulting in the water vortex becoming turbulent, and the dust cannot be effectively captured and settled by the water, and will be discharged with the purified gas, thus resulting in incomplete dust removal.

[0016] (2) The self-cleaning explosion-proof vortex wet dust collector and method described in this invention uses the water flow to drive the gas to flow, and the water flow impacts the rotating component to drive it to rotate. Then, the rotating component, in conjunction with the transmission component, drives the cleaning component to move back and forth to clean the oil and dust in the settling area behind, so as to avoid the oil and dust not being cleaned in time and affecting the subsequent dust removal effect. At the same time, the cleaning component can adaptively adjust the cleaning rate according to the gas flow rate, converting the fluid kinetic energy into mechanical motion, and can achieve liquid surface cleaning without additional energy consumption.

[0020] To make the technical means, technical features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1: As Figure 1 - Figure 9 and Figure 15 - Figure 20 As shown, the self-cleaning explosion-proof vortex wet dust collector of the present invention includes a dust collection box 1 and a water vortex dust collection mechanism 3 arranged inside the dust collection box 1. A self-cleaning mechanism 6 is symmetrically arranged at the bottom of the water vortex dust collection mechanism 3. A water injection mechanism 5 is fixedly connected inside the water vortex dust collection mechanism 3. Multiple sets of water-air separators 4 are arranged inside the dust collection box 1, which are located between the water vortex dust collection mechanism 3 and the dust collection box 1. A support frame 2 is fixedly connected to the bottom of the dust collection box 1. Specifically, during dust removal, a fan draws dust-laden gas into the dust collector 1. The gas then impacts the water surface at a certain speed. First, the gas comes into contact with the water curtain formed by the water injection mechanism 5, removing large dust particles. Next, the gas drives the water flow into the water vortex dust collector 3, creating a vortex. The gas and water are thoroughly mixed, separating internal oil and fine dust. The mixture is then discharged through one side of the water vortex dust collector 3. The water carrying oil and fine dust then flows smoothly into the settling area behind the self-cleaning mechanism 6 and remains suspended on the liquid surface. This prevents the water from directly spraying out and contacting the liquid surface, which would cause violent disturbances and fluctuations, thus breaking the relatively stable oil and dust layer on the liquid surface. This causes some oil and fine dust to resuspend in the liquid, resulting in turbulent water vortex flow, preventing the dust from being effectively removed. Water capture and sedimentation will be discharged with the purified gas, resulting in incomplete dust removal. At the same time, the gas drives the water flow, which drives the rotating component 61 to rotate, thereby driving the cleaning component 63 to move back and forth to clean the oil and dust on the liquid surface of the sedimentation area behind, so as to avoid the residual liquid affecting the subsequent dust removal effect. The water injection mechanism 5 can be set to inject water into the dust removal box 1 through pipes and several nozzles to maintain the liquid content inside the dust removal box 1 and keep it in a stable state. The water injection mechanism 5 is symmetrically arranged inside the water vortex dust removal mechanism 3. The support frame 2 is used to install and fix the dust removal box 1. The water-air separator 4 is located at the upper end of the cleaning component 63. The water-air separator 4 is used to separate the water vapor inside the gas discharged by the water vortex dust removal mechanism 3. It is made of C-shaped, S-shaped or corrugated thin sheets and is made of stainless steel or other anti-corrosion materials.

[0022] In this embodiment, the self-cleaning mechanism 6 includes a rotating component 61 rotatably connected to the dust collection box 1, located at the bottom of the water vortex dust collection mechanism 3. The rotating component 61 is connected to the cleaning component 63. A transmission component 62 is fixedly connected to one side of the rotating component 61, and a guide component 64 is fixedly connected inside the dust collection box 1. The guide component 61 guides the water flow carrying oil and dust discharged from one side of the water vortex dust collection mechanism 3 to flow smoothly into the rear settling area. The rotating component 61 drives the cleaning component 63 to rotate through the transmission component 62.

[0023] Specifically, such as Figure 6 and Figure 15 - Figure 20As shown, the rotating component 61 is located at the bottom of the diversion plate 321 and does not contact the diversion plate 321. When the dust-laden gas impacts the water surface, it drives the water flow to exert an impact force on the rotating component 61, causing it to rotate. The transmission component 62 is used to transmit the rotational power of the rotating component 61 to the cleaning component 63, causing it to reciprocate to clean the oil and dust on the liquid surface in the rear settling zone. The rear settling zone is the area between the water vortex dust removal mechanism 3 and the dust removal box 1. The dust-laden gas drives the water flow through the water vortex dust removal mechanism 3 and falls into the dust removal box 1. Larger particles in the water flow settle, while fine dust and oil that cannot settle remain suspended on the liquid surface. The cleaning component 63, through the rotating component 61 and the transmission component 62, cleans the water. The power transmitted reciprocates to clean the surface of the liquid, removing oil and dust. The guide component 64 is S-shaped, with a large curvature at the front and a small curvature at the rear. The guide component 64 is used to guide the mixed liquid carrying oil and dust discharged by the water vortex dust removal mechanism 3 to flow smoothly into the settling area behind. The self-cleaning mechanism 6 can automatically match the cleaning rate according to the flow rate of the dust-laden gas. When the flow rate of the dust-laden gas is high, the amount of oil and dust generated by the water vortex dust removal mechanism 3 increases accordingly. At the same time, the rotation speed of the rotating component 61 increases, thereby increasing the reciprocating speed of the cleaning component 63, thus improving the dust removal efficiency of oil and dust. Conversely, the internal components of the self-cleaning mechanism 6 can also be set to any other structure that can achieve the same effect.

[0024] In this embodiment, the rotating assembly 61 includes a rotating shaft 611 rotatably connected to the dust collection box 1. Rotating blades 612 are uniformly distributed and fixedly connected to the outside of the rotating shaft 611. The rotating blades 612 are arc-shaped and their bending direction is opposite to the gas flow direction. The end of the rotating blades 612 away from the rotating shaft 611 is shaped like a spoon and has a friction block inside to increase friction.

[0025] Specifically, such as Figure 15 and Figure 20 As shown, the rotating component 61 is located at the bottom of the water cyclone dust removal mechanism 3. The outer side of the rotating blade 612 is not in contact with the bottom of the water cyclone dust removal mechanism 3. When the gas carries the water flow, it drives the rotating blade 612 to rotate. The scoop-shaped setting at one end of the rotating blade 612, combined with the disturbance generated by the water flow, drives the large dust particles to the bottom of the cone. When the dust-laden gas carries the water flow into the water cyclone dust removal mechanism 3, it impacts the rotating blade 612, which in turn drives the rotating shaft 611 to rotate and drive the transmission component 62. At the same time, the water flow impacting the rotating blade 612 can drive the large particles to the scoop-shaped end of the rotating blade 612, and as the rotating blade 612 rotates, it accelerates the large dust particles to settle to the bottom of the cone.

[0026] In this embodiment, the cleaning component 63 includes a protective mounting member 631 fixedly connected to the dust collection box 1 and a sliding block 633 slidably installed inside the protective mounting member 631. The end of the transmission member 62 away from the rotating component 61 is fixedly connected to a reciprocating screw 632, both ends of which are rotatably connected to the dust collection box 1. The bottom end of the sliding block 633 is rotatably connected to a cleaning component 634. A self-locking component 635 is provided at the connection between the rotating component 61 and the cleaning component 634. Dust collection boxes 636 are symmetrically arranged inside the dust collection box 1. The cleaning component 63 is located between the water vortex dust removal mechanism 3 and the dust collection box 1.

[0027] Specifically, such as Figure 16 - Figure 20 As shown, the protective mounting part 631 can protect the reciprocating screw 632 from oil and dust, and can also assist in the installation of the sliding block 633 to make it move smoothly. The reciprocating screw 632 is used to convert the rotational force transmitted by the transmission part 62 into the power of reciprocating movement, thereby driving the cleaning part 634 to reciprocate to clean the liquid surface in the settling area. The reciprocating screw is a precision component that realizes mechanical transmission through a spiral groove structure. Its core feature is that when the main shaft rotates in one direction, it drives the slider to complete the axial reciprocating motion. The sliding block 633 is used to install the cleaning part 634. The cleaning part 634 can be set as a cleaning scraper to scrape off the oil and dust on the liquid surface in the settling area. The upper opening on one side of the dust collection box 636 is set as an arc shape, and the top of the dust collection box 636 is higher than the bottom of the cleaning part 634. When the cleaning component 634 carries dust and oil into the dust collection box 636, the arc-shaped design on one side of the dust collection box 636 causes the cleaning component 634 to rotate. It then engages with the self-locking component 635 to maintain its tilt angle. Simultaneously, when the cleaning component 634 leaves the dust collection box 636, it contacts the non-arc side of the arc-shaped part at the opening of the dust collection box 636, allowing it to adjust its angle and clean one side of the cleaning component 634, removing any remaining impurities. The self-locking component 635 also helps maintain the tilted position, scraping away oil and dust. The bottom of the dust collection box 636 is connected to the drain pipe at the bottom of the dust collector 1 via a pipe. The self-locking component 635 includes a spring telescopic rod and a dome block at the bottom of the spring telescopic rod. The contact surface between the cleaning component 634 and the sliding block 633 has evenly distributed dome grooves. These dome grooves, in conjunction with the self-locking component 635, enable the cleaning component 634 to self-lock after tilting.

[0028] In this embodiment, the water vortex dust removal mechanism 3 includes a partition 31 fixedly installed inside the dust removal box 1 and a water vortex generating component 32 fixedly connected to one side of the bottom end of the partition 31. The water vortex generating component 32 is located at the water discharge end of the water vortex generating component 32. The water vortex generating component 32 includes a diverting plate 321 fixedly connected to one side of the bottom end of the partition 31. A first baffle 322 is fixedly installed inside the dust removal box 1. A second baffle 323 is fixedly connected to the bottom of one side of the partition 31 and is located at the upper end of the first baffle 322.

[0029] Specifically, such as Figure 5 - Figure 10 As shown, the separator 31 is used to install the various structures of the water vortex dust removal mechanism 3. The water injection mechanism 5 is installed inside the separator 31. The guide plate 321 is located at the bottom of the separator 31 and is used to guide the dust-laden gas impacting the water flow into the water vortex generating component 32. The first baffle 322 is set as an S-shaped baffle with a large arc design at the bottom and a small arc design at the top. By cooperating with the guide plate 321, it makes the dust-laden gas and water flow vortex, so that they are fully mixed to analyze the oil and fine dust inside the gas. The second baffle 323 is a drainage baffle, which is set at the drainage point at the upper end of the first baffle 322 and has a certain blocking effect on the water flow. The guide member 64 is fixedly connected to the first baffle 322 on the side close to the first baffle 322.

[0030] In this embodiment, the dust collector 1 includes an air inlet 11 on one side and an exhaust end 12 on its top. The bottom of the dust collector 1 is set as an inverted conical dust collection cone bottom 13. The interior of the dust collector 1 is divided into two chambers by a water vortex dust removal mechanism 3 in conjunction with water flow. The chamber located inside the separator 31 is the air inlet chamber 14, and the chamber located between the separator 31 and the dust collection box 636 is the exhaust chamber 15.

[0031] Specifically, the inlet end 11 is used to connect the pipeline to transport dust-laden gas into the dust collector 1, the exhaust end 12 is used to connect the induced draft fan to discharge the separated clean gas, the dust collection cone bottom 13 is used to collect large dust particles carried in the dust-laden gas, and its bottom is equipped with a valve with an actuator, and discharges the internal dust through the connecting pipeline. The inlet chamber 14 is the chamber in which the dust-laden gas flows into the dust collector 1 and remains, and the exhaust chamber 15 is the chamber in which the clean gas after separating oil and dust is discharged. The inlet chamber 14 and the exhaust chamber 15 are sealed by water flow. The water flow inside the dust collector 1 is kept at a constant height, and its liquid level is higher than the guide plate 321. Dust removal is carried out by fully mixing the dust-laden gas and the water flow, which effectively prevents the occurrence of explosion.

[0032] Example 2: Figure 10 - Figure 14As shown, based on Embodiment 1, the water vortex dust removal mechanism 3 further includes a buffer guide assembly 33 that is slidably connected inside one side of the separator 31. The buffer guide assembly 33 includes a guide plate 331 that is slidably connected to the separator 31. A fixing rod 332 is slidably installed inside the guide plate 331. Both ends of the fixing rod 332 are fixedly connected to the separator 31. Springs 333 are symmetrically arranged on the outside of the fixing rod 332.

[0033] Specifically, the buffer guide assembly 33 is located above the first baffle 322, and the bottom end of the guide plate 331 is located above the guide member 64 and is not in contact with the guide member 64. Multiple sets of mounting blocks are provided on the upper end of the guide plate 331. The guide plate 331 is slidably connected to the separator 31 through the multiple sets of mounting blocks, in conjunction with the fixing rod 332 and the spring 333. The fixing rod 332 is located inside the mounting block, and the spring 333 is symmetrically arranged about the mounting blocks. After the gas and water flow are mixed and separated inside the water vortex generator assembly 32, they are discharged through the upper end of the first baffle 322. The gas drives the water flow to impact the guide plate 331, causing its compression spring 333 to slide on the separator 31. This prevents the water flow from being ejected through elastic buffering, and guides the water flow to fall onto the guide member 64 at a relatively stable speed. The water then flows smoothly into the sedimentation area behind through the guide member 64, preventing the water flow from being ejected in the form of a jet, which would cause the dust and oil carried inside the water flow to be carried out by the gas again. The buffer guide component 33 can also be set to any other structure that can achieve the same effect. In this embodiment, the buffer guide component 33 replaces the second baffle 323.

[0034] A dust removal method for a self-cleaning explosion-proof vortex wet dust collector, the method being as follows: S1: The required water level is injected into the dust collector 1 through the water injection mechanism 5, and then the dust-laden gas is introduced into the dust collector 1 through the induced draft fan. S2: Dust-laden gas impacts the water surface at a certain speed, first contacting the water curtain to separate large dust particles, and then driving the water flow into the water vortex dust removal mechanism 3. The first baffle 322 and the guide plate 321 cooperate to form a vortex, separating oil and fine dust through centrifugal action. After being fully mixed with the water flow, it is discharged through the upper end of the first baffle 322. S3: Water carrying oil and dust flows smoothly into the rear settling area through the buffer guide component 33 and the diversion component 64, while clean gas flows upward and is separated from water and gas by the water-gas separator 4 before being discharged. S4: At the same time, when the dust-laden gas drives the water flow, it impacts the rotating blades 612 and drives the rotating component 61 to rotate, which in turn, in conjunction with the transmission component 62, drives the cleaning component 63 to reciprocate, and uses the cleaning component 634 to clean the oil and dust on the surface of the settling area. S5: The dust deposited at the bottom of the dust collection cone 13 is then discharged through the valve for further processing.
