Description
Technical Field
[0001] This invention relates to the field of waste gas treatment technology, specifically to a waste gas treatment device for steel plants that is easy to clean. Background Technology
[0002] Steel mills generate large amounts of waste gas during production, containing various pollutants such as particulate matter, sulfur dioxide, and nitrogen oxides, posing significant threats to the environment and human health. Therefore, effective waste gas treatment equipment is crucial for steel mills. However, traditional waste gas treatment equipment for steel mills faces numerous challenges in cleaning. Firstly, the complex internal structure of the equipment, with many hard-to-reach corners and crevices, makes comprehensive cleaning difficult, leaving some pollutants behind and affecting treatment effectiveness and equipment lifespan. Secondly, the cleaning process for some equipment is cumbersome, requiring significant manpower, resources, and time, increasing operating costs. For example, disassembling and assembling equipment for cleaning is not only time-consuming but can also damage components due to improper operation. Furthermore, pollutants in steel mill waste gas are sticky and corrosive, easily adhering to the inner walls and treatment components of the equipment, further increasing cleaning difficulty. Long-term accumulation of pollutants can also lead to equipment blockage and corrosion, reducing operating efficiency and stability, and even causing safety accidents.
[0003] Existing waste gas treatment equipment in steel plants generally faces serious problems during operation, leading to decreased equipment performance, increased operating resistance, increased energy consumption, and even forced shutdowns for maintenance. The difficulties in cleaning and maintenance mainly lie in the high concentration of fine, sticky dust (which easily adheres to and accumulates on the inner walls of the equipment, the surfaces of filter bags / plates / wires, the spray layer, demister blades, and catalyst surfaces, gradually hardening and hardening). This dust adhesion problem is particularly severe when the waste gas has high humidity or when temperature fluctuations cause condensation. Summary of the Invention
[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a waste gas treatment device for steelmaking plants that is easy to clean, comprising a treatment pipe, an air inlet connected to the side of the treatment pipe, a mixing device connected to the top of the treatment pipe, an air intake device connected to the side of the air inlet, a collection device connected to the bottom of the treatment pipe, and a fixed base fixedly connected to the bottom of the collection device.
[0005] The mixing device includes an arc-shaped outer shell. A gas guide pipe is connected to the bottom of the arc-shaped outer shell, and a spraying assembly is fixedly connected to the top of the arc-shaped outer shell. A loop-shaped pipe is connected to the side of the spraying assembly, and a water inlet pipe is connected to the top of the loop-shaped pipe. A stirring assembly is fixedly connected to the center of the top of the arc-shaped outer shell. The water inlet pipe passes through the bottom of the stirring assembly and is fixedly connected to it. The bottom of the gas guide pipe is fixedly connected to the top of the treatment pipe. Exhaust gas is introduced along the gas inlet device and flows along the treatment pipe. The exhaust gas, being at a high temperature, rises and envelops the loop-shaped pipe and the bottom of the stirring assembly, thereby heating the injected water flow. The water flow is then introduced through the water inlet pipe. The stirring assembly dissolves alkaline substances and atomizes the alkaline substances and water flow inside the spraying assembly, allowing the water containing alkaline substances to combine with the exhaust gas, thus treating the exhaust gas.
[0006] Preferably, the spraying assembly includes a fixed base, a fixed tube threadedly connected to the inner wall of the fixed base, a sliding seat fixedly connected to the inner wall of the fixed tube, a sliding screw threadedly connected to the top of the sliding seat, an adjusting nut threadedly connected to the top of the sliding screw, a slip ring fixedly connected to the bottom of the adjusting nut, a sliding groove adapted to the slip ring fixedly connected to the top of the fixed tube, a liquid inlet pipe connected to the side of the fixed tube, a water delivery pipe connected to the side of the fixed tube away from the liquid inlet pipe, an adjusting assembly fixedly connected to the bottom of the sliding screw, a fixed connection between the bottom of the fixed base and the top of the arc-shaped outer shell, a liquid inlet pipe connected to the side of the stirring assembly, and a water delivery pipe connected to the side of the loop-shaped pipeline.
[0007] Preferably, the adjustment component includes an arc-shaped base, an arc-shaped limiting seat is sleeved and slidably connected to the side of the arc-shaped base, the side of the arc-shaped limiting seat is fixedly connected to the inner wall of the fixing tube, and the top of the arc-shaped base is fixedly connected to the bottom of the sliding screw.
[0008] Preferably, the stirring assembly includes a stirring tank, an arc-shaped bottom plate fixedly connected to the inner wall of the stirring tank, an arc-shaped guide plate fixedly connected to the top of the arc-shaped bottom plate, a side of the stirring tank fixedly connected to the side of the arc-shaped outer shell, and a top of the arc-shaped guide plate fixedly connected to the side of the water inlet pipe. Alkaline substances are introduced along the liquid inlet pipe, and water is introduced along the water delivery pipe. The water and alkaline substances mix inside the fixed pipe at the top of the sliding seat, causing the fan blades to rotate, thereby increasing the mixing degree of the alkaline substances and water flow. Furthermore, the eccentric design of the liquid inlet pipe and the slip ring increases the tangential force of the water flow, thus promoting the mixing of water and alkaline substances. The water flow descends along the opening at the top of the sliding seat, and the adjusting screw is rotated... The nut, when adjusted, rotates along the slip ring, causing the sliding screw to rise or fall. The sliding screw moves along the sliding seat, which in turn moves the arc-shaped base. This movement of the arc-shaped base changes the distance between itself and the arc-shaped limit seat, thus achieving different flow rates to handle different types of waste gas. Furthermore, alkaline substances and water are mixed through the inlet pipe and the inner wall of the mixing tank. The arc-shaped guide plate creates a fixed angle for the alkaline substances, facilitating their dissolution. The arc-shaped design of the base plate concentrates the heat of the waste gas at its bottom, heating the alkaline substances and water, accelerating their dissolution, and thus aiding in the neutralization of the waste gas by the water flow.
[0009] Preferably, the air intake device includes a ventilation pipe, a fan bracket is fixedly connected to the inner wall of the ventilation pipe, a first motor is fixedly connected to the side of the fan bracket, a fixing hole is opened on the side of the drive shaft of the first motor, a fixing shaft is threadedly connected to the inner wall of the fixing hole, a rotating sleeve is sleeved and slidably connected to the side of the drive shaft of the first motor, a pneumatic fan blade is fixedly connected to the side of the rotating sleeve, and the side of the ventilation pipe communicates with the side of the air inlet. When the first motor is started, the first motor rotates and drives the rotating sleeve to rotate, the rotating sleeve rotates and drives the pneumatic fan blade to rotate, the pneumatic fan blade rotates and drives the air to flow, thereby driving the exhaust gas to be introduced along the inner wall of the ventilation pipe. The fixing hole and the fixing shaft enable quick installation and removal of the rotating sleeve, thereby facilitating the cleaning of the side of the pneumatic fan blade after long-term operation, thus facilitating equipment maintenance.
[0010] Preferably, the collection device includes a mixing tube, the bottom of which is connected to a guide pool, the bottom of which is connected to a lower connector, and the side of the mixing tube is connected to a side connector. A rotating assembly is rotatably connected to the top of the inner wall of the guide pool. The bottom of the guide pool is fixedly connected to the top of a fixed base, and the top of the rotating assembly is connected to the bottom of the processing tube. After careful selection and optimization from numerous design options, we finally determined a high-performance collection device. The core of this device consists of several cleverly designed components to achieve efficient and precise collection. First, the key component of the device is the mixing tube, which acts like a precise mixing center, providing an ideal space for mixing different substances. Its bottom is tightly connected to the guide pool, ensuring that the mixed substances flow smoothly into the guide pool. The guide pool is ingeniously designed, playing a crucial role in guiding and converging substances, allowing them to flow downwards in an orderly manner. The bottom of the guide pool is connected to the lower connector, which acts like a precise... The precise channel accurately transports the material in the guide tank to the next processing stage, while the side of the mixing tube connects to a side connector, providing an inlet for the injection of other materials, further enriching the material composition within the mixing tube. A rotatable rotating component is installed at the top of the inner wall of the guide tank. This component acts like a flexible agitator, thoroughly stirring and mixing the material in the guide tank to ensure uniformity. The bottom of the guide tank is firmly fixed to the top of the fixed base, providing stable support for the entire device. The top of the rotating component connects to the bottom of the processing tube. After thorough mixing and processing, the material enters the processing tube through the rotating component for further processing. All components of the collection device work closely together to form an efficient and stable material collection and processing system, providing strong support for achieving the intended function. This ingenious design not only improves collection efficiency but also ensures the quality of material processing, showing broad prospects and high practical value in real-world applications.
[0011] Preferably, the rotating assembly includes a rotating pool, a first through hole at the bottom of its inner wall, an arc-shaped fan blade fixedly connected to the bottom of the bottom of the inner wall of the rotating pool, a second through hole at the side of the inner wall of the rotating pool, a gas supply pipe rotatably connected to the bottom of the inner wall of the rotating pool, a third through hole at the side of the gas supply pipe, a rotating part of a bearing fixedly connected to the bottom of the rotating pool, a fixed part of the bearing fixedly connected to the bottom of the inner wall of a guide pool, and the top of the third through hole communicating with the bottom of a treatment pipe. The waste gas mixed with water flows downwards along the inner wall of the treatment pipe, and the water flows into the rotating pool. The gas flows internally along the first through hole and moves along the third through hole. When the gas passes through the third through hole, it drives the arc-shaped fan blades to push, thereby driving the rotating pool to rotate. The rotating pool rotates under the support of the bearings, and the rotation of the arc-shaped fan blades drives the water flow to move along the second through hole, thereby promoting the circulation of water inside the mixing pipe. This allows the water to fully dissolve with the waste gas. At the same time, the wastewater is guided by the guide pool to facilitate the distribution and discharge of water. The water flow can be replaced through the side joint and the bottom joint for easy cleaning.
[0012] This invention provides a waste gas treatment device for steel plants that is easy to clean. It has the following beneficial effects:
[0013] 1. This easy-to-clean waste gas treatment equipment for steel plants is equipped with a loop pipeline. Waste gas is introduced along the inlet device and flows along the treatment pipe. The waste gas is at a high temperature, causing it to rise. The waste gas wraps around the bottom of the loop pipeline and the stirring component, thereby heating the injected water flow. The water flow is then introduced through the water inlet pipe. The stirring component is used to dissolve alkaline substances and atomizes the alkaline substances and water flow inside the spraying component. This allows the water flow containing alkaline substances to combine with the waste gas, thereby treating the waste gas.
[0014] 2. This easy-to-clean waste gas treatment equipment for steel plants is equipped with a water supply pipe. Alkaline substances are introduced along the inlet pipe, and water is introduced along the water supply pipe. The water and alkaline substances mix inside the fixed pipe at the top of the sliding seat, driving the fan blades to rotate, thereby increasing the mixing degree of alkaline substances and water flow. The eccentric design of the inlet pipe and slip ring increases the tangential force of the water flow, thus promoting the mixing of water and alkaline substances. The water flow descends along the opening at the top of the sliding seat. Rotating the adjusting nut causes the adjusting nut to rotate along the slip ring, thereby driving the sliding screw to rise or fall. The rod moves along the sliding seat, and the sliding screw moves, causing the arc-shaped base to move. The movement of the arc-shaped base changes the distance between it and the arc-shaped limit seat, thereby achieving different flow rates to cope with different types of exhaust gases. The alkaline substances and water flow mix through the inlet pipe and the inner wall of the mixing tank, and the arc-shaped guide plate creates a fixed angle for the alkaline substances, which facilitates their dissolution. The arc-shaped design of the base plate concentrates the heat of the exhaust gas at the bottom of the base plate, thereby heating the alkaline substances and water flow, accelerating the dissolution of the alkaline substances, and thus facilitating the neutralization of the exhaust gas by the water flow.
[0015] 3. This easy-to-clean waste gas treatment equipment for steel plants is equipped with a first motor. The rotation of the first motor drives the rotating sleeve to rotate, which in turn drives the pneumatic fan blades to rotate. The rotation of the pneumatic fan blades causes air to flow, thereby guiding the waste gas along the inner wall of the ventilation duct. The rotating sleeve can be quickly installed and disassembled through the setting of fixed holes and fixed shafts, which facilitates the cleaning of the sides of the pneumatic fan blades after long-term operation, thus facilitating equipment maintenance.
[0016] 4. This easy-to-clean waste gas treatment equipment for steel plants is equipped with a rotating pool. The waste gas mixed with water flows down along the inner wall of the treatment pipe. The water enters the interior of the rotating pool and flows along the first through hole, while the gas moves along the third through hole. When the gas passes through the third through hole, the gas drives the arc-shaped fan blades to push, thereby driving the rotating pool to rotate. The rotating pool rotates under the support of bearings, and the rotation of the arc-shaped fan blades drives the water to move along the second through hole, thereby promoting the circulation of water inside the mixing pipe. This allows the water to fully dissolve with the waste gas. At the same time, the wastewater is guided by the guide pool, which facilitates the distribution and discharge of water. The water flow can be changed through the side joint and the bottom joint, making cleaning convenient. Attached Figure Description

Detailed Implementation
[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] Please see Figures 1-2The present invention provides a technical solution: a waste gas treatment device for steelmaking plants that is easy to clean, including a treatment pipe 1, an air inlet 2 connected to the side of the treatment pipe 1, a mixing device 3 connected to the top of the treatment pipe 1, an air intake device 4 connected to the side of the air inlet 2, a collection device 5 connected to the bottom of the treatment pipe 1, and a fixed base 6 fixedly connected to the bottom of the collection device 5.
[0028] The air inlet 2 introduces the exhaust gas, and the mixing device 3 sprays water to combine and dissolve the exhaust gas with the water flow. This causes the water flow that dissolves the exhaust gas to descend, and the alkaline substances are melted and mixed with the water. The mixture is then sprayed out by the mixing device 3 to neutralize the acid and alkali in the exhaust gas, thus treating the exhaust gas. The quick-release design of the air inlet 4 reduces maintenance difficulty and facilitates cleaning of the air inlet 4. The collection device 5 uses the guiding force and the power of gas dissolution to drive the water flow, thereby promoting the dissolution of water and exhaust gas and further combining the exhaust gas with the alkaline water flow.
[0029] The mixing device 3 includes an arc-shaped outer shell 301, with an air guide pipe 302 connected to the bottom of the arc-shaped outer shell 301, a spraying assembly 303 fixedly connected to the top of the arc-shaped outer shell 301, a loop pipe 304 connected to the side of the spraying assembly 303, a water inlet pipe 305 connected to the top of the loop pipe 304, a stirring assembly 306 fixedly connected to the center of the top of the arc-shaped outer shell 301, the water inlet pipe 305 passing through the bottom of the stirring assembly 306 and fixedly connected to the stirring assembly 306, and the bottom of the air guide pipe 302 fixedly connected to the top of the processing pipe 1.
[0030] The exhaust gas is introduced along the air intake device 4 and flows along the treatment pipe 1. The exhaust gas is at a high temperature and rises. The exhaust gas wraps around the bottom of the loop pipe 304 and the stirring component 306, thereby heating the injected water flow. The water flow is then introduced through the water inlet pipe 305. The stirring component 306 is used to dissolve alkaline substances and atomizes the alkaline substances and water flow inside the spraying component 303. This allows the water flow containing alkaline substances to combine with the exhaust gas, thereby treating the exhaust gas.
[0031] Please see Figures 1-5The present invention provides a technical solution: the spraying assembly 303 includes a fixed base 3031, a fixed tube 3032 threadedly connected to the inner wall of the fixed base 3031, a sliding base 3033 fixedly connected to the inner wall of the fixed tube 3032, a sliding screw 3034 slidably connected through the top of the sliding base 3033, an adjusting nut 3035 threadedly connected to the top of the sliding screw 3034, a slip ring 3036 fixedly connected to the bottom of the adjusting nut 3035, and the top of the fixed tube 3032 is fixedly... The fixed connection has a sliding groove that matches the slip ring 3036. The side of the fixed pipe 3032 is connected to the liquid inlet pipe 3037. The side of the fixed pipe 3032 away from the liquid inlet pipe 3037 is connected to the water supply pipe 3038. The bottom of the sliding screw 3034 is fixedly connected to the adjustment component 3039. The bottom of the fixed seat 3031 is fixedly connected to the top of the arc-shaped outer shell 301. The liquid inlet pipe 3037 is connected to the side of the stirring component 306. The water supply pipe 3038 is connected to the side of the loop pipe 304.
[0032] The adjustment component 3039 includes an arc-shaped base 30391, an arc-shaped limiting seat 30392 is sleeved and slidably connected to the side of the arc-shaped base 30391, the side of the arc-shaped limiting seat 30392 is fixedly connected to the inner wall of the fixing tube 3032, and the top of the arc-shaped base 30391 is fixedly connected to the bottom of the sliding screw 3034.
[0033] The mixing assembly 306 includes a mixing tank 3061, an arc-shaped bottom plate 3062 fixedly connected to the inner wall of the mixing tank 3061, an arc-shaped guide plate 3063 fixedly connected to the top of the arc-shaped bottom plate 3062, a side of the mixing tank 3061 fixedly connected to the side of the arc-shaped outer shell 301, and a top of the arc-shaped guide plate 3063 fixedly connected to the side of the water inlet pipe 305.
[0034] Alkaline substances are introduced through the inlet pipe 3037, and water is introduced through the water supply pipe 3038. The water and alkaline substances mix inside the fixed pipe 3032 at the top of the sliding seat 3033, causing the fan blades to rotate. This increases the mixing degree between the alkaline substances and the water flow. The eccentric design of the inlet pipe 3037 and the slip ring 3036 increases the tangential force of the water flow, further promoting mixing. The water flows down through the opening at the top of the sliding seat 3033. Rotating the adjusting nut 3035 causes it to rotate along the slip ring 3036, thereby driving the sliding screw 3034 to rise or fall. The sliding screw 3034 moves along the sliding seat 3033. The sliding screw 3034 moves, causing the arc-shaped base 30391 to move. The movement of the arc-shaped base 30391 changes the distance between it and the arc-shaped limit seat 30392, thereby achieving different flow rates to cope with different types of waste gas. The alkaline substances and water flow mix through the water inlet pipe 305 and the inner wall of the mixing tank 3061. Under the action of the arc-shaped guide plate 3063, the alkaline substances are fixed at a fixed angle, which facilitates the dissolution of alkaline substances. The arc design of the arc-shaped base plate 3062 concentrates the heat of the waste gas at the bottom of the arc-shaped base plate 3062, thereby heating the alkaline substances and water flow, thereby accelerating the dissolution of alkaline substances and facilitating the neutralization of waste gas by the water flow.
[0035] Please see Figures 1-6 The present invention provides a technical solution: the air intake device 4 includes a ventilation pipe 401, a fan bracket 402 is fixedly connected to the inner wall of the ventilation pipe 401, a first motor 403 is fixedly connected to the side of the fan bracket 402, a fixing hole 404 is opened on the side of the drive shaft of the first motor 403, a fixing shaft 405 is threadedly connected to the inner wall of the fixing hole 404, a rotating sleeve 406 is sleeved and slidably connected to the side of the drive shaft of the first motor 403, a pneumatic fan blade 407 is fixedly connected to the side of the rotating sleeve 406, and the side of the ventilation pipe 401 communicates with the side of the air intake 2.
[0036] The first motor 403 is started, and its rotation drives the rotating sleeve 406 to rotate. The rotation of the rotating sleeve 406 drives the pneumatic fan blade 407 to rotate, which in turn drives the air to flow. This causes the exhaust gas to be introduced along the inner wall of the ventilation pipe 401. The rotating sleeve 406 can be quickly installed and removed through the combination of the fixing hole 404 and the fixing shaft 405. This facilitates the cleaning of the side of the pneumatic fan blade 407 after long-term operation, thus making equipment maintenance easier.
[0037] Please see Figures 1-8The present invention provides a technical solution: the collection device 5 includes a mixing tube 501, the bottom of the mixing tube 501 is connected to a guide pool 502, the bottom of the guide pool 502 is connected to a lower connector 503, the side of the mixing tube 501 is connected to a side connector 504, the top of the inner wall of the guide pool 502 is rotatably connected to a rotating component 505, the bottom of the guide pool 502 is fixedly connected to the top of the fixed base 6, and the top of the rotating component 505 is connected to the bottom of the processing tube 1.
[0038] The rotating assembly 505 includes a rotating pool 5051. A first through hole 5052 is provided at the bottom of the inner wall of the rotating pool 5051. An arc-shaped fan blade 5053 is fixedly connected to the bottom of the inner wall of the rotating pool 5051. A second through hole 5054 is provided on the side of the inner wall of the rotating pool 5051. An air supply pipe 5055 is rotatably connected to the bottom of the inner wall of the rotating pool 5051. A third through hole 5056 is provided on the side of the air supply pipe 5055. A rotating part of a bearing 5057 is fixedly connected to the bottom of the rotating pool 5051. The fixed part of the bearing 5057 is fixedly connected to the bottom of the inner wall of the guide pool 502. The top of the third through hole 5056 communicates with the bottom of the processing pipe 1.
[0039] The waste gas mixed with water flows down along the inner wall of the treatment pipe 1. The water flows into the interior of the rotating pool 5051 and flows along the first through hole 5052. The gas moves along the third through hole 5056. When the gas passes through the third through hole 5056, the gas drives the arc-shaped fan blade 5053 to push it, thereby driving the rotating pool 5051 to rotate. The rotating pool 5051 rotates under the support of the bearing 5057, and under the rotation of the arc-shaped fan blade 5053, it drives the water to move along the second through hole 5054, thereby promoting the circulation of water inside the mixing pipe 501, so that the water can fully dissolve with the waste gas. At the same time, the wastewater is guided by the guide pool 502 to facilitate the discharge of water. The water flow is replaced through the side connector 504 and the bottom connector 503, which facilitates cleaning.
[0040] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
