Description

Technical Field

[0001] This invention relates to the field of copper smelting technology, specifically to a dust removal and fume extraction device for copper smelting equipment. Background Technology

[0002] In the copper processing industry, copper smelting is one of the core production links. However, this link generates a large amount of high-temperature dusty flue gas. If such flue gas is discharged or leaked directly without effective treatment, it will cause environmental pollution problems. Moreover, copper dust leaked in the workshop will be inhaled by operators and will be deposited in the respiratory tract and lungs. Long-term exposure can easily cause pneumoconiosis and endanger occupational health. In untreated flue gas, large dust particles will wear down parts with the airflow and shorten the life of equipment.

[0003] However, existing dust removal and smoke extraction equipment has low dust removal efficiency, is difficult to separate large dust particles in flue gas, is prone to clogging equipment parts, and requires shutdown and disassembly for cleaning, making maintenance difficult and inefficient.

[0004] Meanwhile, traditional dust removal and smoke extraction equipment suffers from uneven water distribution, small liquid-gas contact area, and poor adsorption of fine particles during dust removal, resulting in incomplete dust removal, low water resource utilization, and the fact that traditional dust removal and smoke extraction equipment mostly uses water only once, resulting in high water consumption and wastewater discharge that pollutes the environment and increases costs. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dust removal and fume extraction device for copper smelting equipment, comprising:

[0006] The housing has an air inlet pipe fixedly installed at the bottom of its outer surface. The air inlet pipe is used to introduce high-temperature dusty flue gas generated during copper smelting. An air inlet hopper is fixedly installed at the air inlet end of the air inlet pipe. The air inlet hopper adopts a flared structure to increase the flue gas collection range and improve the air intake efficiency. An air outlet hopper is fixedly installed at the middle of the top of the housing. The air outlet hopper is used to discharge the purified flue gas. A suction fan is fixedly installed inside the air outlet hopper. The suction fan drives the high-temperature dusty flue gas to enter from the air inlet hopper, and after being processed by the internal mechanism of the housing, it is discharged from the air outlet hopper. A support frame is fixedly installed at the bottom of the outer surface of the housing, and a frame plate is fixedly installed on the outer surface of the housing.

[0007] The spraying mechanism is installed at the top of the inner cavity of the housing. The spraying mechanism is used to spray water into the housing, thereby increasing the contact area between the water droplets and the dust-laden flue gas. The water droplets can also adsorb tiny particles in the gas. The flue gas particles and water droplets combine to form dust-laden water droplets, which will eventually settle under the action of gravity.

[0008] A dust-blocking mechanism is fixedly installed at the bottom of the inner cavity of the housing. The dust-blocking mechanism is located at the outlet end of the air inlet pipe. The dust-blocking mechanism initially intercepts large dust particles in the dust-laden flue gas.

[0009] The gas distribution mechanism is fixedly installed on the inner wall of the housing and is located directly below the spraying mechanism. The gas distribution mechanism distributes gas evenly so that the flue gas after preliminary dust removal can fully contact the water.

[0010] The spraying mechanism includes a liquid storage tank, which is fixedly installed on the top of a frame. The tank stores liquid water for dust removal. A suction pipe is fixedly installed on the top of the tank, penetrating the tank and extending inside. A suction funnel is fixedly installed at the bottom of the suction pipe, and a water pump is fixedly installed at the top. The suction pipe draws water from the tank. The suction funnel has a funnel-shaped structure to increase the suction area and is located at the bottom of the tank's interior to prevent air suction when the remaining water level is low. A bend is fixedly connected to the outlet end of the water pump, and a water pipe is fixedly connected to the other end of the bend. The water pipe passes through the housing and extends into its interior. The water pump pressurizes the coolant in the storage tank and delivers it to the water pipe through the bend. A fixing plate is fixedly installed at the end of the water pipe away from the bend. The fixing plate is fixedly installed on the inner wall of the housing. Sprinklers are installed on the surface of the water pipe. The sprinklers are evenly distributed on the lower surface of the water pipe. The water pipe distributes the water delivered by the water pump to each sprinkler, ensuring that all areas inside the housing are covered with water droplets.

[0011] Preferably, the water sprinkler includes a water distribution pipe and a water distribution cylinder. The upper surface of the water distribution cylinder is fixedly installed at the bottom of the water distribution pipe, and the water distribution pipe is fixedly installed at the lower surface of the water pipe. The water distribution pipe is used to divert water in the water pipe to the water distribution cylinder. A water outlet pipe is fixedly installed at the bottom of the water distribution cylinder. The water distribution pipe is perpendicular to the axis of the water distribution cylinder. A water guide plate is fixedly installed on the inner wall of the water distribution pipe. A rotating component is rotatably installed in the inner cavity of the water distribution cylinder.

[0012] Preferably, the water guide plate is inclined, and a water guide groove is formed at the edge of the upper surface of the water guide plate. The water guide groove is located on the lower side of the water guide plate. The water guide plate can guide the water in the water distribution pipe to flow into the water guide groove, and then flow into the water distribution cylinder in an orderly manner, so that it impacts the rotating part.

[0013] Preferably, a fixing rod is fixedly installed on the inner wall of the water outlet pipe, and elastic steel plates are fixedly installed on both sides of the fixing rod. A water-blocking rubber block is fixedly installed on the bottom of the outer surface of the elastic steel plate. The water-blocking rubber block is squeezed and adapted to the inner wall of the water outlet pipe. When there is water in the water distribution cylinder, the liquid pressure pushes the elastic steel plate to deform inward, causing the water-blocking rubber block to detach from the inner wall of the water outlet pipe, allowing the coolant to flow out. The water-blocking rubber block achieves the sealing and opening of the water outlet pipe through the deformation of the elastic steel plate, ensuring that there is no water leakage when the equipment is stopped and that the coolant flows out smoothly when the equipment is running.

[0014] Preferably, the rotating component includes a rotating shaft, which is rotatably mounted at both ends of the water distribution cylinder. A turntable is fixedly mounted at the end of the rotating shaft, and the turntable is disposed inside the water distribution cylinder. An installation rod is fixedly connected between the turntables, and a push cylinder is fixedly mounted on the outer surface of the installation rod. When water in the water guide channel impacts the push cylinder, it drives the installation rod and the turntable to rotate, and the water is evenly distributed in the water distribution cylinder.

[0015] Preferably, there are six mounting rods, and the six mounting rods are evenly distributed along the axis of the turntable. A water guide plate is fixedly connected between adjacent push cylinders. The water guide plate is tangential to the outer surface of the push cylinder and is arc-shaped. When rotating, it can guide water to flow along the outer surface of the push cylinder, enhance the rotation speed of the rotating part, and guide the water to the outlet pipe.

[0016] Preferably, the dust-blocking mechanism includes a bending plate, which is fixedly installed at the bottom of the inner cavity of the housing. The bending plate can block the dust-laden flue gas from flowing directly upward, forcing the flue gas to flow along the inner curved surface of the bending plate. The large dust particles are caused to fall after impacting the inner wall of the bending plate by inertia, thus achieving preliminary dust removal. An inclined plate is fixedly installed on the inner curved surface of the bending plate. An air outlet two is opened on the side of the inclined plate away from the bending plate. An air outlet one is opened on the upper surface of the bending plate. The flue gas after preliminary dust removal flows upward through the air outlet two and the air outlet one in sequence.

[0017] Preferably, a cleaning door is rotatably installed at the bottom of the housing. The cleaning door is located directly below the bending plate. A dust guide groove is provided on the inner curved surface of the bending plate. The dust guide groove is located below the inclined plate. The dust guide groove is used to guide dust to slide naturally to the bottom of the housing, making it convenient to clean through the cleaning door and preventing dust from accumulating inside the bending plate.

[0018] Preferably, the gas distribution mechanism includes an inverted truncated cone-shaped liquid receiving plate and a truncated cone-shaped air guiding plate. Both the inverted truncated cone-shaped liquid receiving plate and the truncated cone-shaped air guiding plate are fixedly installed on the inner wall of the housing. The truncated cone-shaped air guiding plate is located directly below the inverted truncated cone-shaped liquid receiving plate and is located inside the truncated cone-shaped air guiding plate. A sealing ring is fixedly installed between the inverted truncated cone-shaped liquid receiving plate and the truncated cone-shaped air guiding plate. An oblique hole is opened on the surface of the inverted truncated cone-shaped liquid receiving plate and is located inside the truncated cone-shaped air guiding plate. The inverted truncated cone-shaped liquid receiving plate can collect dust-laden liquid droplets to prevent liquid accumulation inside the housing. The truncated cone-shaped air guiding plate and the inverted truncated cone-shaped liquid receiving plate form an annular gap. The flue gas passing through the dust blocking mechanism enters this gap from below and enters the inverted truncated cone-shaped liquid receiving plate through the oblique hole to fully contact the water droplets sprayed by the spraying mechanism, thereby achieving secondary dust removal.

[0019] Preferably, a drain pipe is fixedly installed at the middle of the bottom of the inverted frustum-shaped liquid receiving plate. The drain pipe penetrates the shell and extends to its bottom. The oblique hole is inclined downward toward the middle of the inverted frustum-shaped liquid receiving plate to allow flue gas to pass through, while preventing liquid droplets on the surface of the inverted frustum-shaped liquid receiving plate from passing through, so that the liquid droplets are discharged only through the drain pipe. A liquid outlet valve is rotatably installed inside the drain pipe.

[0020] This invention provides a dust removal and fume extraction device for copper smelting equipment. It has the following beneficial effects:

[0021] I. The dust removal and fume extraction equipment of this copper smelting equipment, through the setting of the air inlet hopper and the suction fan, starts the suction fan in the exhaust hopper. The operation of the fan generates a stable negative pressure, forming an air pressure difference between the inside and outside of the equipment. The high-temperature dust-laden flue gas generated by copper smelting flows towards the air inlet end of the air inlet pipe due to the suction force of the negative pressure. It first contacts the flared air inlet hopper, and then enters the inner cavity of the shell at a uniform speed through the air inlet pipe. The flared design of the air inlet hopper realizes the efficient collection and guidance of flue gas. The stable negative pressure and the gathered flue gas can avoid airflow turbulence, provide a uniform airflow for the subsequent dust removal mechanism, and ensure the overall dust removal efficiency.

[0022] II. The dust removal and fume extraction equipment of this copper smelting equipment, through the setting of the dust blocking mechanism and the cleaning door, allows the dust-laden flue gas to be discharged from the inlet pipe and impact the bending plate of the dust blocking mechanism, forcing it to flow along the inner curved surface. Large dust particles collide with the inner wall of the bending plate due to inertia, and the intercepted dust accumulates directly above the cleaning door. The initially purified flue gas flows upward through the second and first outlets. When the dust accumulates to a certain amount, the cleaning door can be opened to directly clean the dust. The bending plate and the inclined plate use the principle of inertia to achieve the initial separation of large dust particles. The cleaning door, together with the dust guide trough, realizes the centralized collection and rapid cleaning of dust, improving the continuous operation efficiency of the equipment.

[0023] 3. The dust removal and smoke extraction equipment of this copper smelting equipment, through the setting of the spraying mechanism, the water pump draws water from the storage tank through the water suction pipe and water suction bucket, pressurizes it and delivers it to the water pipe through the bend pipe, and then distributes it to each spraying component. The water guide plate in the water distribution pipe guides the water flow to the water guide trough, impacts the rotating component in the water distribution cylinder, drives the push cylinder and water guide plate to rotate, so that the water flow is evenly distributed. The water pressure pushes the elastic steel plate in the water outlet pipe to deform, the water blocking rubber block detaches from the inner wall, and the water flow is evenly sprayed, increasing the contact area with the flue gas and improving the adsorption efficiency of fine particles.

[0024] IV. The dust removal and fume extraction equipment of this copper smelting equipment, through the coordinated design of the gas distribution mechanism and the liquid spraying mechanism, allows the initially purified flue gas to enter the annular gap of the gas distribution mechanism, achieving uniform gas distribution. The flue gas and liquid droplets are in full contact, and the tiny dust particles adhere to the liquid droplets through inertial collision and adsorption, forming dust-laden liquid droplets. The dust-laden liquid droplets slide down the liquid receiving plate to the drain pipe, and can be discharged by opening the liquid outlet valve. The inclined hole prevents the liquid droplets from entering the flue gas channel. The inverted frustum-shaped liquid receiving plate and the frustum-shaped air guide plate work together to extend the contact time between the flue gas and the liquid droplets, achieving secondary dust removal of tiny particles, thus significantly reducing the dust content of the discharged flue gas.

[0025] V. The dust removal and fume extraction equipment of this copper smelting equipment, through the setting of a liquid storage tank and a drain pipe, allows for the injection of dust removal water into the liquid storage tank before the equipment is started. The liquid storage tank is stably fixed by a frame plate to provide a continuous water source for the spraying mechanism. During the dust removal process, the water from the spraying mechanism forms dust-laden droplets after use, which are collected through an inverted frustum-shaped liquid receiving plate and flow into the drain pipe. The discharged dust-laden droplets can undergo solid-liquid separation, and the treated clean water can be reinjected into the liquid storage tank for recycling, reducing water waste.

[0038] First embodiment, such as Figures 1 to 9 As shown, the present invention provides a technical solution: a dust removal and fume extraction device for copper smelting equipment, comprising:

[0039] The shell 1 has an air inlet pipe 2 fixedly installed at the bottom of its outer surface. The air inlet pipe 2 is used to introduce high-temperature dusty flue gas generated by copper smelting. An air inlet hopper 3 is fixedly installed at the air inlet end of the air inlet pipe 2. The air inlet hopper 3 adopts a flared structure to increase the flue gas collection range and improve the air intake efficiency. An air outlet hopper 5 is fixedly installed at the middle of the top of the shell 1. The air outlet hopper 5 is used to discharge the purified flue gas. A suction fan 11 is fixedly installed inside the air outlet hopper 5. The suction fan 11 drives the high-temperature dusty flue gas to enter from the air inlet hopper 3, and after being processed by the internal mechanism of the shell 1, it is discharged from the air outlet hopper 5. A support frame 8 is fixedly installed at the bottom of the outer surface of the shell 1, and a frame plate 9 is fixedly installed on the outer surface of the shell 1.

[0040] The spraying mechanism 4 is installed on the top of the inner cavity of the housing 1. The spraying mechanism 4 is used to spray water into the housing 1, while increasing the contact area between the water droplets and the dust-laden flue gas. The water droplets can also adsorb the tiny particles in the gas. The flue gas particles and water droplets combine to form dust-laden water droplets, which will eventually settle under the action of gravity.

[0041] Dust-blocking mechanism 6 is fixedly installed at the bottom of the inner cavity of housing 1. Dust-blocking mechanism 6 is set at the outlet of air inlet pipe 2. Dust-blocking mechanism 6 initially intercepts large dust particles in dust-laden flue gas.

[0042] The dust-blocking mechanism 6 includes a bending plate 61, which is fixedly installed at the bottom of the inner cavity of the housing 1. The bending plate 61 can block the dust-laden flue gas from flowing directly upward, forcing the flue gas to flow along the inner curved surface of the bending plate 61. The large dust particles are caused to fall after impacting the inner wall of the bending plate 61 by inertia, thus achieving preliminary dust removal. An inclined plate 63 is fixedly installed on the inner curved surface of the bending plate 61. An air outlet 64 is opened on the side of the inclined plate 63 away from the bending plate 61. An air outlet 62 is opened on the upper surface of the bending plate 61. The flue gas after preliminary dust removal flows upward through the air outlet 64 and the air outlet 62 in sequence.

[0043] A cleaning door 10 is rotatably installed at the bottom of the housing 1. The cleaning door 10 is located directly below the bending plate 61. A dust guide groove 65 is provided on the inner curved surface of the bending plate 61. The dust guide groove 65 is located below the inclined plate 63. The dust guide groove 65 is used to guide the dust to slide naturally to the bottom of the housing 1, so that it can be cleaned through the cleaning door 10 and to prevent the dust from accumulating inside the bending plate 61.

[0044] The gas distribution mechanism 7 is fixedly installed on the inner wall of the housing 1. The gas distribution mechanism 7 is located directly below the spraying mechanism 4. The gas distribution mechanism 7 distributes gas evenly so that the flue gas after preliminary dust removal can fully contact the water.

[0045] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 3 to 8 As shown, the spraying mechanism 4 includes a liquid storage tank 41, which is fixedly installed on the top of the frame plate 9. The liquid storage tank 41 is used to store liquid water for dust removal. A suction pipe 42 is fixedly installed on the top of the liquid storage tank 41, penetrating the liquid storage tank 41 and extending into its interior. A suction bucket 43 is fixedly installed at the bottom of the suction pipe 42, and a water pump 44 is fixedly installed at the top of the suction pipe 42. The suction pipe 42 is used to draw water from the liquid storage tank 41. The suction bucket 43 adopts a funnel-shaped structure to increase the water absorption area. The suction bucket 43 is located at the bottom of the inner cavity of the liquid storage tank 41 to prevent the liquid storage tank 41 from being sucked up when the remaining water is low. The water pump 44... A bend 45 is fixedly connected to the water outlet end, and a water pipe 46 is fixedly connected to the other end of the bend 45. The water pipe 46 passes through the housing 1 and extends into its interior. The water pump 44 pressurizes the coolant in the storage tank 41 and delivers it to the water pipe 46 through the bend 45. A fixed plate 47 is fixedly installed at the end of the water pipe 46 away from the bend 45. The fixed plate 47 is fixedly installed on the inner wall of the housing 1. A water spraying component 48 is installed on the surface of the water pipe 46. The water spraying component 48 is evenly distributed on the lower surface of the water pipe 46. The water pipe 46 distributes the water delivered by the water pump 44 to each water spraying component 48. The water spraying component 48 ensures that all areas inside the housing 1 are covered by water droplets.

[0046] The water sprinkler component 48 includes a water distribution pipe 481 and a water distribution cylinder 482. The upper surface of the water distribution cylinder 482 is fixedly installed at the bottom of the water distribution pipe 481. The water distribution pipe 481 is fixedly installed at the lower surface of the water pipe 46. The water distribution pipe 481 is used to divert water in the water pipe 46 to the water distribution cylinder 482. A water outlet pipe 483 is fixedly installed at the bottom of the water distribution cylinder 482. The water distribution pipe 481 is perpendicular to the axis of the water distribution cylinder 482. A water guide plate 485 is fixedly installed on the inner wall of the water distribution pipe 481. A rotating component 484 is rotatably installed in the inner cavity of the water distribution cylinder 482.

[0047] The water guide plate 485 is inclined, and a water guide groove 486 is provided at the edge of the upper surface of the water guide plate 485. The water guide groove 486 is located on the lower side of the water guide plate 485. The water guide plate 485 can guide the water in the water distribution pipe 481 to flow into the water guide groove 486, and then flow into the water distribution cylinder 482 in an orderly manner, so that it impacts the rotating part 484.

[0048] A fixing rod 487 is fixedly installed on the inner wall of the water outlet pipe 483. Elastic steel plates 488 are fixedly installed on both sides of the fixing rod 487. A water-blocking rubber block 489 is fixedly installed on the bottom of the outer surface of the elastic steel plate 488. The water-blocking rubber block 489 is squeezed and matched with the inner wall of the water outlet pipe 483. When there is water in the water distribution cylinder 482, the liquid pressure pushes the elastic steel plate 488 to deform inward, causing the water-blocking rubber block 489 to detach from the inner wall of the water outlet pipe 483, so that the coolant flows out. The water-blocking rubber block 489 achieves the sealing and opening of the water outlet pipe 483 through the deformation of the elastic steel plate 488, ensuring that there is no water leakage when the equipment is stopped and that the coolant flows out smoothly when the equipment is running.

[0049] The rotating component 484 includes a rotating shaft 4841, which is rotatably mounted at both ends of the water distribution cylinder 482. A turntable 4842 is fixedly mounted at the end of the rotating shaft 4841. The turntable 4842 is located inside the water distribution cylinder 482. An installation rod 4843 is fixedly connected between the turntables 4842. A pusher 4844 is fixedly mounted on the outer surface of the installation rod 4843. When the water in the water guide trough 486 impacts the pusher 4844, it drives the installation rod 4843 and the turntable 4842 to rotate, and the water is evenly distributed in the water distribution cylinder 482.

[0050] There are six mounting rods 4843, and the six mounting rods 4843 are evenly distributed along the axis of the turntable 4842. Water guide plates 4845 are fixedly connected between adjacent push cylinders 4844. The water guide plates 4845 are tangential to the outer surface of the push cylinder 4844. The water guide plates 4845 are arc-shaped. When rotating, they can guide water to flow along the outer surface of the push cylinder 4844, enhance the rotation speed of the rotating part 484, and guide the water to the outlet pipe 483.

[0051] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figure 10 As shown, the gas distribution mechanism 7 includes an inverted frustum-shaped liquid receiving plate 71 and a frustum-shaped gas guiding plate 72. Both the inverted frustum-shaped liquid receiving plate 71 and the frustum-shaped gas guiding plate 72 are fixedly installed on the inner wall of the housing 1. The frustum-shaped gas guiding plate 72 is positioned directly below the inverted frustum-shaped liquid receiving plate 71, and the inverted frustum-shaped liquid receiving plate 71 is positioned inside the frustum-shaped gas guiding plate 72. A sealing ring 74 is fixedly installed between the inverted frustum-shaped liquid receiving plate 71 and the frustum-shaped gas guiding plate 72. An oblique hole 73 is provided on the surface of the liquid tray 71. The oblique hole 73 is located inside the frustum-shaped air guide plate 72. The inverted frustum-shaped liquid receiving plate 71 can receive dust-laden liquid droplets to prevent liquid accumulation inside the shell 1. The frustum-shaped air guide plate 72 and the inverted frustum-shaped liquid receiving plate 71 form an annular gap. The flue gas passing through the dust blocking mechanism 6 enters the gap from below and enters the inverted frustum-shaped liquid receiving plate 71 through the oblique hole 73 to fully contact the water droplets sprayed by the spraying mechanism 4 to achieve secondary dust removal.

[0052] A drain pipe 75 is fixedly installed at the middle of the bottom of the inverted truncated cone-shaped liquid receiving plate 71. The drain pipe 75 penetrates the housing 1 and extends to its bottom. The inclined hole 73 is inclined downward toward the middle of the inverted truncated cone-shaped liquid receiving plate 71 to allow flue gas to pass through, while preventing liquid droplets on the surface of the inverted truncated cone-shaped liquid receiving plate 71 from passing through, so that the liquid droplets are discharged only through the drain pipe 75. A liquid outlet valve 76 is rotatably installed inside the drain pipe 75.

[0053] During use, the operator starts the suction fan 11. The fan generates negative pressure, and the high-temperature dust-laden flue gas generated by copper smelting is efficiently gathered by the air intake hopper 3 and flows into the inner cavity of the housing 1 through the air intake pipe 2. After the dust-laden flue gas is discharged from the air outlet of the air intake pipe 2, it impacts the bending plate 61. Large dust particles in the flue gas collide with the inner wall of the bending plate 61, achieving initial interception. After initial interception, the flue gas is guided by the inclined plate 63 to achieve further dust removal. The intercepted dust accumulates along the dust guide groove 65 to the area directly above the cleaning door 10, waiting for subsequent cleaning.

[0054] After initial purification, the flue gas flows upward through the second air outlet 64 on the inclined plate 63 and the first air outlet 62 on the bent plate 61, and enters the air distribution mechanism 7 area. At this time, the water pump 44 is turned on, and the water suction pipe 42 draws the dust removal water stored in the liquid storage tank 41 through the water suction bucket 43 at the bottom. After the water pump 44 pressurizes the water, it is delivered to the water pipe 46 through the bent pipe 45. The water pipe 46 is fixed to the inner wall of the housing 1 by the fixing plate 47 to ensure the position is stable and to evenly distribute the water flow to the water spraying parts 48 that are evenly distributed on the surface.

[0055] After the water flow is received by the water distribution pipe 481 of the sprinkler component 48, the inclined water guide plate 485 inside guides the water flow to the water guide groove 486 on the edge, so that the water flow is concentrated and orderly flowing into the water distribution cylinder 482. After the water flow flows into the water distribution cylinder 482 from the water guide groove 486, it impacts the push cylinder 4844 of the internal rotating component 484. The push cylinder 4844 is fixed on the mounting rod 4843 that is evenly distributed along the axis of the turntable 4842. After being impacted by the water flow, it drives the turntable 4842 and the rotating shaft 4841 to rotate. At the same time, the water guide plate 4845 between adjacent push cylinders 4844 guides the water flow along the push cylinder 4844, enhancing the stirring effect, making the water flow evenly distributed in the water distribution cylinder 482, and increasing the rotation speed.

[0056] The liquid pressure inside the water distribution cylinder 482 pushes the elastic steel plates 488 on both sides of the fixing rod 487 on the inner wall of the water outlet pipe 483 to deform inward, causing the water-blocking rubber block 489 to detach from the inner wall of the water outlet pipe 483, and the water flow is evenly sprayed from the water outlet pipe 483 to the air distribution mechanism 7 below.

[0057] The flue gas, which has been initially purified by the dust-blocking mechanism 6, flows upward to the gas distribution mechanism 7. It enters the inclined hole 73 through the annular gap between the frustum-shaped air guide plate 72 and the inverted frustum-shaped liquid receiving plate 71. The flue gas enters the area above the inverted frustum-shaped liquid receiving plate 71 evenly through the inclined hole 73. The flue gas and the liquid droplets are in full contact. The tiny particles in the flue gas are attached to the liquid droplets through inertial collision and adsorption, forming dust-laden liquid droplets, thus achieving secondary dust removal. The dust-laden liquid droplets slide down the surface of the frustum-shaped air guide plate 72 to the bottom of the inverted frustum-shaped liquid receiving plate 71 and are collected through the drain pipe 75.

[0058] Operators can discharge dust-laden droplets from the equipment by controlling the outlet valve 76 in the drain pipe 75 for subsequent processing. At the same time, the tilt angle of the inclined hole 73 can prevent droplets on the surface of the liquid receiving tray from flowing back into the flue gas channel. After the flue gas is purified by the dust blocking mechanism 6 for initial dust removal and the air distribution mechanism 7 and the spraying mechanism 4 for secondary dust removal, it continues to flow upward and is discharged from the equipment through the air outlet hopper 5 at the top of the housing 1 under the continuous drive of the suction fan 11, thus completing the entire dust removal and smoke exhaust process.
