Description

Technical Field

[0001] This invention relates to the field of exhaust gas treatment machines, specifically a pure water washing exhaust gas treatment machine with self-cleaning function. Background Technology

[0002] In precision manufacturing fields such as semiconductors, photovoltaics, LEDs, and flat panel displays, large quantities of toxic, harmful, corrosive, or flammable and explosive process exhaust gases are generated during production. If these exhaust gases are emitted directly without treatment, they not only severely pollute the environment but also pose a direct threat to the personal safety of operators. Water-washing exhaust gas treatment equipment has become the mainstream exhaust gas purification method in the industry due to its advantages such as high treatment efficiency, relatively low operating costs, and wide applicability. However, this treatment equipment still has some shortcomings in its use.

[0003] Blockage in drainage pipes is one of the most common and difficult-to-cure failure modes in the long-term operation of pure water-washing exhaust gas treatment equipment. During operation, soluble gases in the exhaust gas are absorbed by water to form corresponding acid, alkali, or salt solutions, which are discharged through the drainage pipes. However, as the washing solution continues to circulate and concentrate, the concentration of dissolved salts gradually increases. When the concentration exceeds its solubility limit, the salts crystallize out of the solution, forming hard scale on the inner wall of the drainage pipe. Solid particles carried in the exhaust gas, byproducts of chemical reactions, and precipitates generated during the washing process also gradually deposit and accumulate in the drainage pipe, further aggravating the blockage. Existing equipment typically requires shutting down the upstream production equipment and having personnel disassemble and clean the pipes when dealing with blockages. This is not only time-consuming and labor-intensive but also seriously affects the continuous operation and capacity output of the production line. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a pure water washing exhaust gas treatment machine with self-cleaning function. It can achieve pure water washing of exhaust gas, and can also use the kinetic energy of drainage to automatically clean the pipeline, reducing energy consumption while ensuring the cleanliness of the device.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A self-cleaning pure water washing exhaust gas treatment machine includes:

[0007] The main body is connected to an air intake and an exhaust duct, and the inner cavity of the main body is equipped with a first spray head and a second spray head;

[0008] The drainage section includes a drainage tank, the upper end of which is connected to a water inlet pipe, which is connected to the lower end of the main body, and a filter plate is fixedly connected to the inner cavity of the drainage tank.

[0011] When the drain tank drains water, the airbag and lifting ring move downwards, while the water flow drives the spiral blade and drive rod to rotate, which in turn drives the rotating rod and scraper to rotate and clean the water inlet pipe. The descending lifting ring drives the rotating rod and scraper to descend synchronously, thus thoroughly cleaning the water inlet pipe.

[0012] Preferably, the upper left side of the main body is connected to an air intake channel, and the upper right side is connected to an exhaust channel. A water outlet ring is fixedly connected to the upper end of the inner cavity of the air intake channel, a first spray head is installed on the left side of the inner cavity of the main body, and an adsorption block is provided on the right side of the inner cavity of the main body.

[0013] Preferably, a water pump is located at the lower right side of the main body. The inlet of the water pump extends into the lower end of the inner cavity of the main body, and the outlet of the water pump is connected to a water supply pipe. The water supply pipe has two sets of outlets. One set of outlets is located above the adsorption block, and the other set of outlets is connected to a second spray head. The second spray head is fixedly installed at the upper end of the inner cavity of the main body. A fan is installed at the upper right side of the exhaust duct, and the outlet of the fan is located inside the exhaust duct.

[0014] Preferably, the drain box is installed below the main body, and the upper inlet of the drain box is connected to a water inlet pipe, which is located below the main body.

[0015] Preferably, a filter plate is fixedly installed in the inner cavity of the drainage tank, and a baffle is rotatably connected to the right side of the filter plate through a sealed bearing. A right-end motor is fixedly installed on the rear side of the drainage tank, and the output shaft of the motor extends into the inner cavity of the drainage tank and is fixedly connected to the rotating shaft of the baffle. A partition is provided on the right side of the inner cavity of the drainage tank at the position of the right side of the baffle, and a seepage plate is fixedly installed below the partition. A drainage pipe is connected to the lower left side of the drainage tank.

[0016] Preferably, a lifting ring is slidably connected to the drain tank below the filter plate, and an airbag is fixedly installed below the lifting ring.

[0017] Preferably, a rotating rod is rotatably connected to the middle of the lifting ring via a sealed bearing, and a scraper is fixedly connected to the upper end of the rotating rod, with the scraper adhering to the inner wall of the water inlet pipe.

[0018] Preferably, a spiral blade is rotatably connected to the inlet of the drain pipe via a sealed bearing, and a drive rod is fixedly connected to the upper end of the spiral blade's shaft. The upper end of the drive rod has its inner and outer rings slidably connected to the inner cavity of the rotating rod.

[0019] Preferably, an electrically controlled valve is installed at the outlet of the drain pipe, a trigger plate is fixedly connected to the left side of the lifting ring, and two sets of control buttons are fixedly installed on the left side of the inner cavity of the drain section. The two sets of control buttons are located on the upper and lower sides of the trigger plate.

[0020] Preferably, a connecting groove is provided at the lower end of the spiral blade, a connecting rod is movably sleeved in the middle of the drain pipe, the upper end of the connecting rod is located below the connecting groove, and the lower end of the connecting rod extends out of the drain pipe and is fixedly connected to a handle.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. The main body of this invention can achieve pure water washing of exhaust gas, ensuring the cleaning effect and avoiding damage to the environment; when in use, exhaust gas is connected to the air intake, and the exhaust gas is cleaned and adsorbed by the first spray head and the second spray head before being discharged from the exhaust duct, thus achieving the cleaning of exhaust gas.

[0023] 2. The drainage section, control section, and cleaning section of the present invention can automatically clean the pipeline using the kinetic energy of drainage, reducing energy consumption while ensuring the cleanliness of the device. When the water inside the main body becomes too turbid during use, the water is drained into the drainage tank and filtered through the filter plate. The water then falls below the filter plate. As the water level rises, the airbag and lifting ring also rise synchronously until the lifting ring triggers the control button to drain the water from the drainage tank. At this time, the water flow will drive the spiral blade to rotate, and the spiral blade will drive the rotating rod and scraper to rotate through the drive rod to clean the water inlet pipe. At the same time, as the water level drops, the lifting ring and rotating rod will also drop synchronously to thoroughly clean the inside of the water inlet pipe.

[0024] 3. The control unit of the present invention can perform manual active cleaning when encountering stubborn deposits, ensuring the cleaning effect and efficiency; when encountering stubborn deposits that cannot be automatically cleaned, the drive structure in the control unit can be manually operated to embed its upper end into the spiral blade to form a transmission connection; then the drive structure can be rotated to drive the spiral blade and the rotating rod to rotate synchronously, so that the scraper can force mechanical scraping of the inner wall of the water inlet pipe, ensuring the stable progress of the cleaning operation.

[0037] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0038] like Figures 1 to 10 As shown, this embodiment provides a pure water washing exhaust gas treatment machine with self-cleaning function, including:

[0039] The main body 10 is connected to an air intake duct 11 and an exhaust duct 12. The inner cavity of the main body 10 is equipped with a first spray head 14 and a second spray head 18.

[0040] The drainage section 20 includes a drainage tank 21. The upper end of the drainage tank 21 is connected to a water inlet pipe 22, which is connected to the lower end of the main body 10. A filter plate 23 is fixedly connected to the inner cavity of the drainage tank 21.

[0041] The cleaning unit 30 includes a lifting ring 31, an airbag 32 connected to the lower end of the lifting ring 31, a rotating rod 33 rotatably connected to the inner ring of the lifting ring 31, a scraper 34 connected to the upper end of the rotating rod 33, a spiral blade 35 rotatably connected to the lower end of the drain tank 21, a drive rod 36 fixedly connected to the upper end of the spiral blade 35, and the drive rod 36 slidably connected inside the rotating rod 33.

[0042] The control unit 40 includes an electric control valve 41, which is located below the drain tank 21. Control buttons 43 are installed on both the upper and lower sides of the inner cavity of the drain tank 21, and the lifting ring 31 is located between the two sets of control buttons 43.

[0043] When the drain tank 21 drains water, the airbag 32 and the lifting ring 31 move downwards. At the same time, the water flow drives the spiral blade 35 and the drive rod 36 to rotate, which in turn drives the rotating rod 33 and the scraper 34 to rotate and clean the water inlet pipe 22. The descending lifting ring 31 drives the rotating rod 33 and the scraper 34 to descend synchronously, thus cleaning the water inlet pipe 22 completely.

[0044] It should be noted that, in order to ensure the stable operation and use of the device, the device should be equipped with corresponding electrical control units and drive units, and connected to the various components and mains power in the device to ensure that the device can be installed with the predetermined program and operate stably.

[0045] In this embodiment, during use, the air intake duct 11 is connected to the exhaust gas. At this time, the exhaust gas passes through the first spray head 14 and the second spray head 18 to clean and adsorb impurities before being discharged from the exhaust duct 12. When the water in the main body 10 becomes too turbid, it is drained into the drain tank 21 and filtered by the filter plate 23. Subsequently, the water falls below the filter plate 23. As the water level rises, the airbag 32 and the lifting ring 31 also rise synchronously until the lifting ring 31 triggers the control button 43, causing the drain tank 21 to drain. At this time, the water flow drives the spiral blade 35 to rotate, and the spiral blade 35 drives the rotating rod 33 and the scraper 34 to rotate via the drive rod 36, cleaning the water inlet pipe 22. Simultaneously, as the water level drops, the lifting ring 31 and the rotating rod 33 also drop synchronously, thoroughly cleaning the inside of the water inlet pipe 22 until the lifting ring 31 triggers the control button 43 below, stopping the drain tank 21 from draining, and waiting for the next drainage and cleaning operation.

[0046] Please refer to it again. Figures 1 to 3 The upper left side of the main body 10 is connected to an air intake 11, and the upper right side is connected to an exhaust 12. The upper end of the inner cavity of the air intake 11 is fixedly connected to a water outlet ring 13. The left side of the inner cavity of the main body 10 is equipped with a first spray head 14, and the right side of the inner cavity of the main body 10 is provided with an adsorption block 15.

[0047] A water pump 16 is located at the lower right end of the main body 10. The inlet of the water pump 16 extends into the lower end of the inner cavity of the main body 10. The outlet of the water pump 16 is connected to a water supply pipe 17. The water supply pipe 17 has two sets of outlets. One set of outlets is located above the adsorption block 15, and the other set of outlets is connected to a second spray head 18. The second spray head 18 is fixedly installed at the upper end of the inner cavity of the main body 10. A fan 19 is installed at the upper right end of the exhaust duct 12. The outlet of the fan 19 is located inside the exhaust duct 12.

[0048] It should be noted that the first spray head 14 and the water outlet ring 13 share a pipeline for liquid transportation, and this pipeline should be connected to an external drive pump and water source to ensure that the device can stably output water for exhaust gas cleaning.

[0049] The air outlet of the fan 19 is set upwards to allow the gas in the exhaust duct 12 to flow upwards with the airflow of the fan 19, ensuring stable gas flow.

[0050] The adsorption block 15 has a spherical structure, which is designed to ensure that the exhaust gas can make stable contact with water over a large area when passing over the adsorption block 15, thus ensuring the cleaning effect.

[0051] In this embodiment, during use, exhaust gas is introduced into the device through the air inlet 11. The water outlet ring 13 first sprays water onto the incoming exhaust gas for preliminary impurity treatment. Then, the exhaust gas passes through the first spray head 14, where the water sprayed from the first spray head 14 performs a first water wash on the exhaust gas, removing most of the soluble impurities and solid particles. After that, the exhaust gas passes through the adsorption block 15. The water pump 16 extracts water from the lower end of the inner cavity of the main body 10 and sends it to the top of the adsorption block 15 to rinse the adsorption block 15. At the same time, the water flow further contacts the exhaust gas, performing a second purification to remove residual impurities. Another path is sent to the second spray head 18, where the water sprayed from the second spray head 18 enters the adsorption block 15 to ensure the cleaning effect. After purification, the exhaust gas is discharged from the exhaust duct 12 under the action of the fan 19, completing the exhaust gas purification process.

[0052] Please refer to it again. Figures 4 to 5 , Figure 8 The drain tank 21 is installed below the main body 10. The upper inlet of the drain tank 21 is connected to the water inlet pipe 22, which is located below the main body 10.

[0053] A filter plate 23 is fixedly installed in the inner cavity of the drainage tank 21. A baffle 24 is rotatably connected to the right side of the filter plate 23 via a sealed bearing. A right-end motor 25 is fixedly installed on the rear side of the drainage tank 21. The output shaft of the motor 25 extends into the inner cavity of the drainage tank 21 and is fixedly connected to the rotating shaft of the baffle 24. A partition is provided on the right side of the inner cavity of the drainage tank 21 at the right side of the baffle 24, and a seepage plate 26 is fixedly installed below the partition. A drain pipe 27 is connected to the lower left side of the drainage tank 21.

[0054] It should be noted that a door is provided on the right side of the drainage tank 21 for cleaning the residue accumulated on the seepage board 26.

[0055] In this state, the baffle 24 is tilted upward to ensure that the liquid can flow smoothly through the filter plate 23 downward. When the filter plate 23 needs to be cleaned, the baffle 24 is directly driven to rotate downward. At this time, after the water enters the drain tank 21, it will wash the filter plate 23, causing some water and residue on the filter plate 23 to slide to the right into the partition of the drain tank 21, which is convenient for cleaning the residue.

[0056] An outlet is provided below the partition on the right side of the drain tank 21 to facilitate the outflow of liquid meat when cleaning the filter plate 23.

[0057] In this embodiment, during use, the wastewater discharged from the main body 10 enters the inner cavity of the drain tank 21 through the inlet pipe 22 and falls onto the filter plate 23 for filtration. The filter plate 23 intercepts solid residues in the wastewater, and the filtered water falls into the space below the filter plate 23 in the drain tank 21. When it is necessary to clean the residues intercepted on the surface of the filter plate 23, the motor 25 drives the baffle 24 to rotate downwards, and the water carrying the residues intercepted on the filter plate 23 is discharged into the right-side partition. The liquid is discharged from the side outlet of the drain tank 21 through the permeation plate 26, while the residues remain on the surface of the permeation plate 26. The tank door can be opened for unified cleaning later.

[0058] Please refer to it again. Figures 5 to 7 The drain tank 21 is slidably connected to the lifting ring 31 below the filter plate 23, and the air bag 32 is fixedly installed below the lifting ring 31.

[0059] The middle part of the lifting ring 31 is rotatably connected to the rotating rod 33 through a sealed bearing. The upper end of the rotating rod 33 is fixedly connected to the scraper 34, which is attached to the inner wall of the water inlet pipe 22.

[0060] The inlet of the drain pipe 27 is rotatably connected to a spiral blade 35 via a sealed bearing. The upper end of the rotating shaft of the spiral blade 35 is fixedly connected to a drive rod 36. The inner and outer rings of the upper end of the drive rod 36 are slidably connected to the inner cavity of the rotating rod 33.

[0061] It should be noted that the scraper 34 has a spiral arc structure, which is designed to ensure stable cleaning of the inner wall of the water inlet pipe 22 when the scraper 34 rotates;

[0062] A guide hole is provided in the middle of the lifting ring 31, and a guide rod is fixedly connected to the lower end of the drainage tank 21. The lifting ring 31 is slidably connected inside the guide rod (e.g., Figure 5 (As shown), to prevent the lifting ring 31 from rotating arbitrarily and affecting the positional stability of the trigger plate 42;

[0063] The inner cavity of the rotating rod 33 is provided with a hexagonal structure, and the upper outer ring of the drive rod 36 is also a hexagonal structure. This is intended to drive the drive rod 36 and the rotating rod 33 to rotate together when the spiral blade 35 is rotated by the water flow. It can also cause the lifting ring 31 to drop due to the drop in the drainage water level, so that the rotating rod 33 can drop and rotate at the same time, thus achieving complete cleaning of the inner cavity of the water inlet pipe 22.

[0064] A valve can be installed at the upper end of the water inlet pipe 22 to facilitate the control of drainage of the main body 10. However, the valve should not be in contact with the scraper 34 under normal conditions to avoid affecting the normal operation of the valve.

[0065] In this embodiment, when the drain pipe 27 drains water, the water flow impacts the spiral blade 35, causing it to rotate. The spiral blade 35 drives the rotating rod 33 and the scraper 34 to rotate synchronously via the drive rod 36. At the same time, as the water level drops, the lifting ring 31 descends smoothly along the guide rod under the action of gravity, so that the scraper 34 can fully cover and scrape the inner wall of the water inlet pipe 22 from top to bottom while rotating, effectively removing the attached salt scale and deposits.

[0066] Please refer to it again. Figures 8 to 10 An electric control valve 41 is installed at the outlet of the drain pipe 27. A trigger plate 42 is fixedly connected to the left side of the lifting ring 31. Two sets of control buttons 43 are fixedly installed on the left side of the inner cavity of the drain section 20. The two sets of control buttons 43 are located on the upper and lower sides of the trigger plate 42.

[0067] A connecting groove 44 is provided at the lower end of the spiral blade 35. A connecting rod 45 is movably sleeved in the middle of the drain pipe 27. The upper end of the connecting rod 45 is located below the connecting groove 44, and the lower end of the connecting rod 45 extends out of the drain pipe 27 and is fixedly connected to a handle 46.

[0068] It should be noted that both sets of control buttons 43 are designed to control the solenoid valve 41. The upper control button 43 controls the solenoid valve 41 to open, while the lower one controls it to close. This is designed so that when the water level reaches a certain height, the trigger plate 42 will approach the upper control button 43 and drive the solenoid valve 41 to open for drainage and cleaning. When the water level drops to a certain level, the lower control button 43 will be triggered to drive the solenoid valve 41 to close the water storage, waiting for secondary drainage and cleaning.

[0069] The connecting groove 44 is hexagonal, and the connecting rod 45 is also hexagonal. This is designed so that when the deposits in the water inlet pipe 22 are too stubborn, the connecting rod 45 can be pushed to connect with the connecting groove 44, and the spiral blade 35 and the rotating rod 33 can be manually driven to rotate, thus ensuring the cleaning effect.

[0070] A sealing gasket is provided on the upper outer ring of the connecting rod 45 to ensure that water will not leak at the connecting rod 45 under normal conditions, thus affecting the normal use of the device.

[0071] In this embodiment, under normal conditions, when the water level in the drain tank 21 reaches a certain level, the rising ring 31, which causes the trigger plate 42 to touch the upper control button 43. After the control button 43 is triggered, the electric control valve 41 opens, and the drain tank 21 begins to drain water outward through the drain pipe. The water level gradually decreases, and the rising ring 31 descends synchronously with the water level until the trigger plate 42 touches the lower control button 43. After the control button 43 is triggered, the electric control valve 41 closes, stopping the drainage and completing one automatic drainage and automatic cleaning process. When encountering stubborn deposits that cannot be automatically cleaned, the connecting rod 45 can be pushed upward by manually operating the handle 46, so that its upper end is embedded in the hexagonal connecting groove 44 at the lower end of the spiral blade 35, forming a transmission connection. Then, rotating the handle 46 will drive the spiral blade 35, the drive rod 36, and the rotating rod 33 to rotate synchronously, so that the scraper 34 performs forced mechanical scraping on the inner wall of the water inlet pipe 22, ensuring the stable progress of the cleaning operation.

[0072] The working principle of this invention is as follows: When in use, after the exhaust gas enters the intake duct 11, it first undergoes preliminary spray cooling and coarse washing through the water outlet ring 13, and then enters the inner cavity of the main body 10. It then passes through the powerful water washing of the first spray head 14, the interception and adsorption of the adsorption block 15, and the deep purification of the second spray head 18 in sequence, achieving multi-stage efficient treatment. The purified gas is stably discharged from the exhaust duct 12 under the suction of the fan 19. At the same time, the washing wastewater accumulated at the bottom of the main body 10 is discharged into the drain tank 21 through the water inlet pipe 22, and is temporarily stored in the lower chamber after being filtered by the filter plate 23. As the water level rises, the buoyancy of the airbag 32 causes the lifting ring 31 to move upward. When the trigger plate 42 touches the upper control button 43, the electric control valve 41 automatically opens to drain water. During drainage, the water flow drives the spiral blade 35 to rotate, which in turn drives the rotating rod 33 and the scraper 34 to rotate synchronously via the drive rod 36. At the same time, the lifting ring 31 moves downward as the water level drops, allowing the scraper 34 to thoroughly scrape the inner wall of the inlet pipe 22 from top to bottom during rotation, removing salt scale and deposits. When the water level drops to the set low level, the trigger plate 42 touches the lower control button 43, and the electric control valve 41 closes, completing one automatic cleaning cycle. If stubborn dirt is encountered, the connecting rod 45 can be manually pushed into the connecting groove 44 by the handle 46 to force transmission and enhance cleaning power, ensuring that the inlet pipe 22 is unobstructed, effectively avoiding downtime maintenance due to blockage, and significantly improving the continuity of equipment operation and production efficiency.

[0073] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
