Description

Technical Field

[0001] This invention relates to the field of vortex wet dust collection technology, specifically to an explosion-proof and scale-resistant vortex wet dust collector and its method. Background Technology

[0002] The vortex wet scrubber achieves high-efficiency dust removal through a dual mechanism of centrifugal separation and water film capture. Dust-laden gas enters the scrubber at a tangential velocity of 15–45 m / s, forming a high-speed rotating airflow. Dust particles are thrown against the scrubber wall under centrifugal force. At this time, the flowing water film formed along the wall or the atomized water droplets sprayed from the top adsorb the dust, forming a droplet-dust mixture, which is eventually discharged with the water flow. The purified gas is then dehydrated by a dehydration device (such as a cyclone dehydrator or a baffle plate) to remove the water droplets, avoiding secondary pollution. The dust concentration after treatment can be reduced to ≤10 mg / Nm³. Its function covers three dimensions: In terms of dust removal, the capture efficiency of 5-200 μm non-sticky dust reaches 80%–95%, especially effective for particles >5 μm. At the same time, it can capture ultrafine particles such as PM2.5.

[0003] The internal components of the vortex wet dust collector are made of stainless steel or non-metallic corrosion-resistant materials. The water quality is kept stable through automatic water replenishment and water level control. The circulating water system is equipped with a filtration device to reduce impurities. The equipment is equipped with a nitrogen injection interface to suppress combustion conditions by replacing oxygen. It also uses an anti-static filter cartridge and grounding structure to ensure that the frictional static charge is discharged in time and to prevent ignition by electric sparks.

[0004] In the aforementioned and similar existing technologies, the fixed guide plates in vortex wet dust collectors are prone to rapid wear due to the continuous impact of high-speed dust-laden airflow, the abrasive effect of dust particles (especially high-hardness mineral dust) on the plate surface, and the inability of the fixed structure to adaptively adjust to disperse the impact force. This leads to a significant increase in maintenance costs. Frequent replacement or repair of the guide plates requires downtime operations, directly affecting production continuity, increasing long-term operation and maintenance costs, and causing fluctuations in dust removal efficiency. Wear-up guide plates may deform or have increased surface roughness, disrupting the preset airflow vortex pattern, weakening the collision efficiency between dust and droplets, and causing turbulence in some areas due to guide plate failure, resulting in dust escape. The structural defects of the fixed guide plates and the physical abrasion of the high-speed dust environment together shorten their lifespan, thereby increasing costs and reducing efficiency.

[0005] Therefore, the present invention provides an explosion-proof and scale-resistant vortex wet dust collector and its method that can dynamically adjust the angle of the guide plate according to the negative pressure generated by the fan to provide protection for the guide plate. Summary of the Invention

[0006] To address the problems in existing vortex wet dust collectors, such as the inability of the fixed guide plate to adaptively adjust and disperse impact force, resulting in significantly increased maintenance costs, an explosion-proof and scale-resistant vortex wet dust collector and its method are designed.

[0007] The technical solution adopted by this invention to solve its technical problem is: an explosion-proof and scale-proof vortex wet dust collector, including a dust collector assembly, a guide plate rotatably connected to the inner side of the dust collector assembly, a back plate rotatably connected to the guide plate, self-locking transmission parts at both ends of the guide plate, a buoyancy plate connected to the other end of the self-locking transmission parts, and a water guide component at the bottom of the guide plate; the self-locking transmission part includes a driven part fixedly connected to both ends of the guide plate, an active part engaging one side of the driven part, the buoyancy plate driving the active part to rotate according to the water level change, the active part and the driven part cooperating to rotate the guide plate, the water level change caused by negative pressure causes the guide plate to contact the airflow at different angles and different wind speeds through the active part and the driven part, and the self-locking capability of the active part and the driven part enables unidirectional power transmission, restricting the guide plate from rotating due to the force on the leeward side.

[0008] Furthermore, the dust collector assembly includes a dust collection tank, a processing tank fixed to the bottom of the dust collection tank, an exhaust cover fixed to the top of the dust collection tank, a vortex chamber fixed to the inner side of the dust collection tank, a gas-liquid separation plate fixed to each of the two inner walls of the dust collection tank, and two other gas-liquid separation plates fixed to each side of the vortex chamber. The gas-liquid separation plates remove entrained moisture through inertial separation and gravity settling. An air inlet is fixed to one end of the dust collection tank.

[0009] Furthermore, baffles are fixed to the inner sides of both ends of the dust removal pipe, and isolation boxes are fixed to the sides of the two baffles that are far apart from each other. The guide plate and the back plate are rotatably connected to the sides of the two baffles that are close to each other. The active part and the driven part are both located inside the isolation box, and the buoyancy plate is slidably connected to the inner side of the baffle.

[0010] Furthermore, toothed plates are fixed at both ends of the buoyancy plate, and toothed posts are fixed on the side of each active part near the toothed plate. The toothed plates and toothed posts mesh with each other. Sealing elements are fixed at the top and bottom of the buoyancy plate, and the sealing elements are fixedly connected to the inside of the partition.

[0011] Furthermore, the sides of the partitions that are far apart from each other are fixed with limit rods by connecting components. The buoyancy plate is slidably engaged with the outside of the limit rod. An elastic element is fixed to the top of the buoyancy plate, and the other end of the elastic element is fixed to the top of the limit rod. The elastic element is located outside the limit rod.

[0012] Furthermore, a throat cavity is provided on the side of the guide plate away from the back plate. The throat cavity is located above the water surface. Through the coupling of the Bernoulli effect and the Venturi effect, a low-pressure adsorption field is formed on the windward side of the guide plate, which dynamically constrains the water into a protective water film. Under the action of airflow shear force, the water film extends into a uniform water film. The water film isolates dust from the surface of the guide plate, reducing the direct impact and wear of hard particles on the metal. At the same time, the high-speed airflow flows parallel to the surface of the guide plate, forming a laminar boundary layer, which "presses" the water film onto the surface of the guide plate. A backwater hole is provided on the side of the guide plate near the back plate. The backwater hole is located below the water surface. A water cavity is provided inside the guide plate. A water tank is provided at the bottom of the water cavity. The water cavity connects the throat cavity, the backwater hole and the water tank. A filter plate is fixed inside the backwater hole.

[0013] Furthermore, the diameter of the throat cavity orifice is smaller than the diameter of any cross section of the backwater hole, the backwater hole is set to be conical and the end with the larger diameter of the backwater hole is close to the back plate, and the filter plate is set to be inverted conical.

[0014] Furthermore, the water guide includes a bottom cavity, which is fixed to the bottom of the guide plate. Water pipes are fixed at both ends of the inner side of the bottom cavity, and the other end of the water pipes is fixed to the bottom of the buoyancy plate through a connecting component. The bottom cavity connects the water pipes and the water tank.

[0015] Furthermore, the usage method of the explosion-proof and scale-resistant vortex wet dust collector:

[0016] S1. Connect the exhaust gas conveying device to the air inlet of the dust collector assembly, and then connect the fan to the air outlet of the dust collector assembly. Use the fan to create negative pressure so that the exhaust gas can circulate in the dust collector assembly.

[0017] S2. Inject water into the inside of the dust collector assembly according to production needs;

[0018] S3. Dust-laden flue gas enters the dust collector assembly. The flue gas impacts the water surface at a high speed. It forms an "S"-shaped channel through the guide plate and back plate, causing the water flow to generate a vortex. The particles and water droplets come into full contact. Through mutual collision, interception and coagulation, the particles settle with the water droplets.

[0019] S4. If the fan power is changed, the water level will change, and the buoyancy plate will move in conjunction with the self-locking transmission part to change and fix the angle of the guide plate.

[0020] The beneficial effects of this invention are:

[0021] (1) The present invention provides an explosion-proof and scale-resistant vortex wet dust collector and its method. The buoyancy plate senses the change in water level difference between the inside and outside of the vortex chamber, and drives the guide plate to rotate through the linkage of the worm gear self-locking transmission part. Simultaneously, the back plate adjusts its angle to form a dynamic windward surface. When the fan power increases, the negative pressure increases, causing the water level to rise. The buoyancy plate rises and pushes the transmission part, which increases the windward angle of the guide plate. The incident direction of the dust-laden airflow changes from vertical impact to oblique shearing. The impact force is decomposed along the tangent direction of the plate surface, significantly reducing the normal stress component. At the same time, the rotation of the guide plate expands the contact area between the airflow and the plate surface, reducing the load per unit area, avoiding stress concentration, and extending the equipment life. The interaction between the airflow and the guide plate changes from instantaneous rigid collision to continuous flexible shearing. The impact energy is gradually dissipated in the vortex motion. The synchronous rotation of the back plate further extends the airflow path, increases the turbulent energy consumption time, and stabilizes the dust removal efficiency.

[0022] (2) The present invention provides an explosion-proof and scale-proof vortex wet dust collector and its method, which is based on the coupling of Bernoulli's equation and Venturi effect. When the dust-laden airflow passes through the throat cavity hole on the windward side of the guide plate, the airflow velocity increases sharply, causing the local static pressure to drop sharply, forming a low-pressure adsorption field. This pressure difference drives the pre-filled water in the water cavity to be continuously drawn to the throat cavity outlet. Under the dynamic balance of airflow shear force and surface tension, a water film adhering to the wall is formed. The thickness of the water film is controlled by the balance of airflow shear force and pressure difference to achieve uniform coverage, thereby physically isolating the hard impact of dust on the metal surface, reducing the wear rate. The dissolved salts are continuously carried away by the water, inhibiting the growth of crystal nuclei such as CaCO3. The water film evaporates and absorbs heat, which lowers the plate temperature and alleviates high-temperature oxidation corrosion. Attached Figure Description

[0037] 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.

[0038] Example: Figures 1-10 As shown, the explosion-proof and scale-resistant vortex wet dust collector of the present invention includes a dust collector assembly. A guide plate 2 is rotatably connected to the inner side of the dust collector assembly. A back plate 8 is synchronously rotatably connected to the guide plate 2. Self-locking transmission parts are provided at both ends of the guide plate 2. A buoyancy plate 5 is connected to the other end of the self-locking transmission part. A water guide 9 is provided at the bottom of the guide plate 2. The self-locking transmission part includes a driven part 3 fixedly connected to both ends of the guide plate 2. An active part 4 is engaged on one side of the driven part 3. The buoyancy plate drives the active part 4 to rotate according to the water level change. The active part 4 and the driven part 3 cooperate to rotate the guide plate 2. The water level change caused by negative pressure causes the guide plate 2 to contact the airflow with different wind speeds at different angles through the active part 4 and the driven part 3. The self-locking capability of the active part 4 and the driven part 3 enables unidirectional power transmission and restricts the guide plate 2 from rotating due to the force on the leeward side.

[0039] In this embodiment, the driving part 4 and the driven part 3 can be configured as a combination of a worm and a worm wheel, or other devices capable of unidirectional power transmission and self-locking. After the fan is started, the fan creates negative pressure in the space formed by the dust collector 12 and the vortex chamber 14. Due to the pressure difference inside the vortex chamber 14, the liquid levels inside and outside the vortex chamber 14 change, causing the water level inside the vortex chamber 14 to be lower than the water level outside the vortex chamber 14. When the water surface outside the vortex chamber 14 contacts the bottom of the buoyancy plate 5, the dust-laden gas... As the airflow passes the bottom of the guide plate 2, if the fan power is increased, the pressure in the space formed by the dust collector 12 and the vortex chamber 14 will be further reduced. This will raise the water level outside the vortex chamber 14 and further increase the airflow velocity. The buoyancy plate 5 will drive the guide plate 2 to rotate through the self-locking transmission part. The guide plate 2 will drive the back plate 8 to rotate synchronously through the combination of sprocket set and chain or gear set and toothed belt. While the wind speed increases, the impact angle between the dust-laden airflow and the guide plate 2 will be changed, reducing the impact force and thus extending the life of the guide plate 2.

[0040] Specifically, the dust collector assembly includes a dust collection tank 12, a processing tank 13 fixed to the bottom of the dust collection tank 12, an exhaust cover 11 fixed to the top of the dust collection tank 12, a vortex chamber 14 fixed to the inner side of the dust collection tank 12, a gas-liquid separation plate 15 fixed to the inner walls of both sides of the dust collection tank 12, two other gas-liquid separation plates 15 fixed to both sides of the vortex chamber 14, and an air inlet 16 fixed to one end of the dust collection tank 12.

[0041] In this embodiment, before using the device, the operator fixes the output end of the exhaust gas transport device to the air inlet 16 and the fan to the top of the exhaust cover 11. Then, water is injected into the dust collection tank 12 and the treatment tank 13 according to actual production needs. The fan is started, and negative pressure is created in the space formed by the dust collection tank 12 and the vortex chamber 14 to draw smoke and water vapor into the vortex chamber 14 through the exhaust gas transport device. Then, the dust-laden airflow is guided by the guide plate 2 and the pressure difference causes it to impact the water surface at high speed, creating violent disturbance. Forced swirling motion is generated in multiple "S"-shaped channels around the guide plate 2 and the back plate 8, which prolongs the gas-liquid contact time and enhances the mass transfer effect. During this process, dust particles are directly captured by collision with water droplets, and tiny particles are also captured. As the airflow flows around the particles, they are trapped by the water film. The resulting dust-laden water mist then enters a high-efficiency water-air separator (in this embodiment, it is a folding plate type, composed of gas-liquid separation plates 15). Through inertial separation and gravity settling, the entrained moisture is removed, ensuring that the humidity of the discharged gas meets the standards and there is no secondary carryover. The bottom of the treatment tank 13 is set in a conical shape, which uses geometric contraction to accelerate particle sedimentation and avoid sludge accumulation. An electric or pneumatic valve with an actuator is installed at the bottom, which can automatically open to discharge sludge at regular intervals or according to the turbidity sensor signal. After being discharged into the trough, it enters the wastewater treatment system of the plant. The water replenishment device of the treatment tank 13 adopts a float valve or a liquid level sensing linkage device to realize automatic water replenishment when there is a shortage of water, without the need for additional power drive, which is in line with the green design concept.

[0042] Specifically, a throat cavity 23 is provided on the side of the guide plate 2 away from the back plate 8, and the throat cavity 23 is located above the water surface. A backwater hole 24 is provided on the side of the guide plate 2 close to the back plate 8, and the backwater hole 24 is located below the water surface. A water cavity 22 is provided inside the guide plate 2, and a water tank 21 is provided at the bottom of the water cavity 22. The water cavity 22 connects the throat cavity 23, the backwater hole 24 and the water tank 21. A filter plate 25 is fixed inside the backwater hole 24. The diameter of the throat cavity 23 is smaller than the diameter of any section of the backwater hole 24. The backwater hole 24 is set as a cone and the end with the larger diameter of the backwater hole 24 is close to the back plate 8. The filter plate 25 is set as an inverted cone. The water guide component 9 includes a bottom cavity 91, which is fixed to the bottom of the guide plate 2. Water pipes 92 are fixed at both ends of the inner side of the bottom cavity 91. The other end of the water pipes 92 is fixed to the bottom of the buoyancy plate 5 through a connecting component. The bottom cavity 91 connects the water pipes 92 and the water tank 21.

[0043] In this embodiment, before starting the fan, water flows into the water cavity 22 through the water pipe 92 under pressure, filling the interior of the water cavity 22 and ensuring that the water level inside the water cavity 22 is consistent with the water level inside the vortex chamber 14. According to Bernoulli's equation, when the fluid velocity increases, its static pressure decreases. The water inside the water cavity 22 is drawn to the throat hole 23 outlet due to the pressure difference. When the airflow passes through the throat hole 23 on the windward side of the guide plate 2, the high-speed airflow forms a jet at the outlet of the channel, causing a significant drop in local static pressure, thereby forming a low-pressure area near the throat hole 23 opening. Through the coupling of the Bernoulli effect and the Venturi effect, a low-pressure adsorption field is formed on the windward side of the guide plate 2, dynamically constraining the water into a protective water film. Under the action of airflow shear force, the water film extends into a uniform water film, and the water film separates... Dust is kept away from the surface of the guide plate 2, reducing the direct impact and wear of hard particles on the metal. At the same time, the high-speed airflow flows parallel to the surface of the guide plate 2, forming a laminar boundary layer, which "presses" the water film onto the surface of the guide plate 2. The water film can also dissolve attached salts, inhibit the formation of scale nuclei, reduce surface temperature, and alleviate high-temperature oxidation corrosion. The back water hole 24 is located at 1 / 3 of the height of the back of the guide plate 2, increasing the reaction time between water and dust-laden gas. When impurities are rushed into the back water hole 24 under the action of centrifugal force, they are gradually deposited on the surface of the filter plate 25 and subsequent impurities are adsorbed. The large hole diameter reduces water flow resistance and ensures that the drainage speed is greater than the water inflow speed. The deposited impurities are discharged under the guidance of the water flow. The filter plate 25 intercepts impurities and uses water flow for self-cleaning to avoid clogging.

[0044] Specifically, baffles 6 are fixed to the inner sides of both ends of the dust removal pipe, and isolation boxes 7 are fixed to the sides of the two baffles 6 that are far apart from each other. The guide plate 2 and the back plate 8 are rotatably connected to the sides of the two baffles 6 that are close to each other. The active part 4 and the driven part 3 are both located inside the isolation box 7. The buoyancy plate 5 is slidably connected to the inner side of the baffle 6. The two ends of the buoyancy plate 5 are fixed with toothed plates 51. The side of each active part 4 that is close to the toothed plate 51 is fixed with a toothed post 41, and the toothed plate 51 and the toothed post 41 are engaged. The top and the top of the buoyancy plate 5 are fixed with a sealing element 53, and the sealing element 53 is fixedly connected to the inner side of the baffle 6.

[0045] In this embodiment, the liquid surface pushes the buoyancy plate 5 to rise, and the buoyancy plate 5 drives the toothed plate 51 to move along the outside of the limiting rod 52 while squeezing the elastic element 1. The toothed plate 51 drives the toothed column 41 to rotate through the meshing action. The toothed column 41 drives the active part 4 to rotate, the active part 4 drives the driven part 3 to rotate, and the driven part 3 drives the guide plate 2 to rotate.

[0046] Specifically, the method of using the explosion-proof and scale-resistant vortex wet dust collector is characterized by:

[0047] S1. Connect the exhaust gas conveying device to the air inlet of the dust collector assembly, and then connect the fan to the air outlet of the dust collector assembly. Use the fan to create negative pressure so that the exhaust gas can circulate in the dust collector assembly.

[0048] S2. Inject water into the inside of the dust collector assembly according to production needs;

[0049] S3. Dust-laden flue gas enters the dust collector assembly. The flue gas impacts the water surface at a high speed. It forms an "S"-shaped channel through the guide plate 2 and the back plate 8, causing the water flow to generate a vortex. The particles and water droplets come into full contact. Through mutual collision, interception and coagulation, the particles settle with the water droplets.

[0050] S4. If the fan power is changed, the water level will change, and the buoyancy plate 5 will move in conjunction with the self-locking transmission part to change and fix the angle of the guide plate 2.

[0051] Working principle: Initial state as follows Figures 1-12 As shown, before using this device, the operator fixes the output end of the waste gas transport device to the air inlet cylinder 16, fixes the fan to the top of the exhaust cover 11, and then injects water into the dust collection tank 12 and the treatment tank 13 according to the actual production needs.

[0052] The blower is started, and negative pressure is created in the space formed by the dust collection tank 12 and the vortex chamber 14 to draw smoke and water vapor into the inside of the vortex chamber 14 through the waste gas transport device. Then, the dust-laden airflow impacts the water surface at high speed, creating violent disturbances and stimulating forced swirling motion in multiple "S"-shaped channels. During this process, dust particles are directly captured by collision with water droplets, and tiny particles are intercepted by the water film as they flow around the airflow. The dust-laden water mist generated then enters the high-efficiency water-air separator to remove entrained moisture. The treatment tank 13 uses geometric contraction to accelerate particle sedimentation. An electric or pneumatic valve with an actuator is installed at its bottom, which can be opened automatically at timed intervals or according to the turbidity sensor signal to discharge slag. After being discharged into the rolling ditch, it enters the plant's wastewater treatment system. The water replenishment device of the treatment tank 13 adopts a float valve or a liquid level sensing linkage device.

[0053] After the fan is started, it creates negative pressure in the space formed by the dust collector 12 and the vortex chamber 14. When the water surface outside the vortex chamber 14 contacts the bottom of the buoyancy plate 5, the dust-laden gas begins to pass over the bottom of the guide plate 2. If the fan power is increased, the pressure in the space formed by the dust collector 12 and the vortex chamber 14 will be further reduced. The liquid surface will push the buoyancy plate 5 to rise. The buoyancy plate 5 will drive the active part 4 to rotate. The active part 4 will drive the driven part 3 to rotate. The driven part 3 will drive the guide plate 2 to rotate. The guide plate 2 will drive the back plate 8 to rotate synchronously, changing the impact angle between the dust-laden airflow and the guide plate 2.

[0054] Before the fan is started, the water flows into the inside of the water chamber 22 through the water pipe 92 under pressure, filling the inside of the water chamber 22. As the high-speed airflow forms a low-pressure zone near the opening of the throat hole 23, the water inside the water chamber 22 is drawn to the outlet of the throat hole 23 due to the pressure difference. Through the coupling of the Bernoulli effect and the Venturi effect, a low-pressure adsorption field is formed on the windward side of the guide plate 2, which dynamically constrains the water into a protective water film.

[0055] If the fan power is reduced, the pressure in the space formed by the dust collector 12 and the vortex chamber 14 will increase, causing the water level outside the vortex chamber 14 to drop and the air velocity to decrease. At this time, the buoyancy plate 5 will move under the elastic force of the elastic element, causing the guide plate 2 to reverse and reset.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.

The interaction between the water pipes and the water tank ensures that the water cavity is filled with water and maintains the water level under atmospheric pressure.

4. The method of using the explosion-proof and scale-resistant vortex wet dust collector according to claim 1, characterized in that: S1. Connect the exhaust gas conveying device to the air inlet of the dust collector assembly, and then connect the fan to the air outlet of the dust collector assembly. Use the fan to create negative pressure so that the exhaust gas can circulate in the dust collector assembly. S2. Inject water into the inside of the dust collector assembly according to production needs; S3. Dust-laden flue gas enters the dust collector assembly. The flue gas impacts the water surface at a high speed. It forms an "S"-shaped channel through the guide plate and back plate, causing the water flow to vortex. The particles and water droplets come into full contact. Through mutual collision, interception and coagulation, the particles settle with the water droplets. S4. If the fan power is changed, the water level will change, and the buoyancy plate will move in conjunction with the self-locking transmission part to change and fix the angle of the guide plate.
