Abstract
Description
Technical Field
[0001] This disclosure relates to the field of waste gas treatment technology, and in particular to a waste gas treatment device for medium-density fiberboard drying. Background Technology
[0002] Medium-density fiberboard (MDF) is a type of engineered wood product made by mechanically separating and chemically treating wood or plant fibers, adding adhesives and waterproofing agents, and then molding them under high temperature and pressure. Currently, the treatment of exhaust gas from fiberboard drying is generally accomplished by dry filters or wet scrubbers. Dry filters use dry filter media to capture solid particles and impurities in liquids or gases to achieve purification. Wet scrubbers, on the other hand, use water to capture dust from the air. When dust-laden gas passes through a water body, the dust collides with the water and adheres to it, and is then separated from the gas through gravity sedimentation or other treatment methods. However, the manufacturing process of fiberboard generates exhaust gas, and conventional exhaust gas treatment devices are too wasteful of water resources, and prolonged treatment of exhaust gas can lead to low filtration capacity.
[0003] According to a patent document with publication number CN215138302U, a medium-density fiberboard drying exhaust gas treatment device includes a housing. The housing includes a treatment box and a power box arranged vertically. An electric motor is fixedly installed on the inner bottom of the power box. A rotating shaft that penetrates and extends into the interior of the treatment box is mounted on a bearing at the top of the power box. A spirally arranged stirring blade is fixedly installed on one end of the rotating shaft inside the treatment box. An air inlet pipe that penetrates and extends into the interior of the treatment box is connected to one side of the treatment box. A water inlet pipe and a drain pipe that penetrate and extend into the interior of the treatment box are respectively connected to the upper and lower ends of the other side of the treatment box. A filter arranged vertically is horizontally fixedly installed above the water inlet pipe inside the treatment box. The treatment box has a perforated plate and an exhaust pipe that extends from the top to the outside of the top. In use, waste gas is introduced into the treatment box through the intake pipe, where water dissolves soluble substances, achieving preliminary filtration. When the detector alarm detects a change in gas concentration, it indicates that the water has fully dissolved enough waste to reach saturation, and the wastewater is then discharged through the drain pipe. This fully utilizes water resources without waste and allows for real-time gas quality monitoring. However, while this solution can monitor gas quality in real time, it cannot disperse the waste gas during use, and it cannot quickly remove impurities adhering to the filter plate after treatment, resulting in inconvenience during use.

[0016] The technical solution provided in this disclosure may include the following beneficial effects: 1. In this invention, the moving cylinder is driven by the pressure of the exhaust gas. The movement of the moving cylinder achieves filtration at the filtration point according to the thrust of the air pressure. Under the push of the air pressure, the moving cylinder enters the interior of the fixed cylinder. The air outlet first contacts half of the filter plate for filtration. The gas filtered by the filter plate undergoes secondary adsorption filtration in the water mist sprayed from the atomizing nozzle. Later, the exhaust gas pressure is reduced, causing the moving cylinder to retract by half the distance, and the air outlet moves to the other half for filtration. When the moving cylinder moves, the silicone ring scrapes and cleans the inner wall of the filter plate. Later, the air intake on one side is closed. As the moving cylinder returns to its original position, the silicone ring pushes the impurities inside out of the fixed cylinder for complete cleaning. 2. In this invention, after the filter plate inside the fixed cylinder is scraped and cleaned, the drive motor is started to drive the rotating disk to rotate. When the rotating disk rotates, the residual water inside the filter plate is centrifuged and dried. After the rotating disk rotates, it returns to the starting position and water mist is continuously sprayed out through the rotating atomizing nozzle of the rotating disk. The water mist is sprayed to different positions of the fixed disk and the barrel body, and the inside of the barrel body is cleaned by spraying water mist. The wastewater after cleaning is discharged from the sewage discharge pipe at the bottom of the barrel body. 3. In this invention, after the exhaust gas inside the barrel is initially filtered and purified, it is injected into the diversion pipe through the connecting box and the connecting barrel. The gas in the diversion pipe enters the interior of the fixed pipe. The gas pressure pushes the rubber diaphragm inside the one-way hole to open. The gas is sprayed into the interior of the purification barrel through the one-way hole. The gas undergoes secondary adsorption in the liquid inside the purification barrel. During adsorption, the right-angle cylinder is moved up and down by the threaded tube. The up and down movement of the right-angle cylinder adjusts the position of the opening on the extraction tube inside the purification barrel. The top opening is always installed at the top of the liquid surface. The extraction tube generates suction force, which draws the gas from the top of the liquid surface in the purification barrel outward. 4. In this invention, the number of openings for air extraction can be adjusted according to the amount of waste gas discharged. Two openings can be moved completely to the top of the liquid surface. The one-way hole is no longer blocked by the inner wall of the extraction tube, and exhaust gas is discharged outwards simultaneously through multiple one-way holes. The gas enters the liquid for adsorption and filtration. The simultaneous extraction of gas through multiple openings accelerates the discharge of gas. In addition, the openings can be completely inserted into the liquid in the later stage. The top opening is sealed by a fixed tube, and the bottom opening cooperates with the one-way hole to generate suction. The suction can draw the waste liquid inside the purification tank into the extraction tube and discharge it outwards, which facilitates the replacement of the purification liquid in the later stage.

The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0021] like Figures 1 to 9As shown, a medium-density fiberboard (MDF) drying exhaust gas treatment device includes: a fixed base 1, with a bracket 16 fixedly installed on the side of the fixed base 1; a barrel 13 fixedly installed inside the fixed base 1; air inlet pipes 14 fixedly installed at both ends of the barrel 13; a drive motor 15 fixedly installed at one end of the barrel 13; a water tank 2 and a filter box 3 fixedly installed on the top of the fixed base 1; and an exhaust assembly 12, including an extraction cylinder 44, with a guide cylinder 45 fixedly installed on one side of the extraction cylinder 44; one end of the guide cylinder 45 is fixedly installed on the filter box 3. A positioning tube 46 is fixed to the other side of the extraction tube 44. A support tube 47 is fixed to one end of the positioning tube 46, and a threaded tube 48 is fixed to one end of the support tube 47. A threaded cylinder 49 is rotatably mounted on the threaded tube 48. An exhaust assembly 28 includes a movable cylinder 37. A connecting cylinder 38 is fixed to one end of the movable cylinder 37. A fixing ring 39 is fixed to the connecting cylinder 38. A silicone ring 40 is fixedly mounted on the side of the fixing ring 39. An air vent 41 is opened on the connecting cylinder 38. A slider 42 is fixed to the side of the movable cylinder 37. In this device, the density fiberboard... Drying exhaust gas treatment requires simultaneous control of solid waste pollution and air pollution. Dust, formaldehyde, and volatile organic compounds are removed through processes such as dust removal, adsorption, and purification. In engineering applications, high-efficiency activated carbon is commonly used for deep adsorption to ensure stable emissions that meet standards. In residential applications, it can be paired with a residential indoor air purifier, utilizing a high-efficiency activated carbon filter to continuously adsorb harmful gases released from the filter media, achieving end-to-end purification from industrial emissions to indoor air. During use, the exhaust gas extracted by the extraction cylinder 44 enters the filter box 3 through the guide cylinder 45. The exhaust gas discharged from the guide cylinder 45 passes through the activated carbon adsorption plate and moisture-absorbing plate inside the filter box 3. Adsorption filtration. Later, the air inlet channel of the guide tube 45 can be closed. When the extraction tube 44 stops air intake, the sludge suction pipe at one end of the extraction tube 44 is started. The sludge suction pipe is connected to the external suction device. The threaded tube 49 is rotated and moved downward. After the threaded tube 49 moves downward, the right-angle tube 50 loses the upward thrust and moves downward by its own gravity. After the right-angle tube 50 moves downward, the extraction tube 51 moves on the fixed tube 20. The bottom opening 52 on the extraction tube 51 is fully inserted into the liquid space. The suction generated by the extraction tube 51 can draw out the liquid inside the purification tank 10 for replacement.
[0022] In this embodiment, a connecting box 29 is fixed to the top of the barrel 13, a connecting barrel 7 is fixed to the top of the connecting box 29, a connecting pipe 18 is fixed to the side of the connecting barrel 7, a diversion pipe 8 is fixed to one end of the connecting pipe 18, the diversion pipe 8 is fixedly installed on the side of the filter box 3, a mounting base 9 is fixed to the top of the filter box 3, a purification barrel 10 is movably installed on the top of the mounting base 9, a support block 22 is welded to the side of the mounting base 9, and a fixing block 11 is welded to the side of the purification barrel 10. The top of the mounting base 9 is fixed with a ring seat 19 and a fixing tube 20 respectively. The fixing tube 20 has a one-way hole 21. One end of the fixing tube 20 is fixed to the diversion tube 8. An extraction tube 51 is movably installed on the fixing tube 20. One end of the extraction tube 51 is fixed with a right-angle cylinder 50. The right-angle cylinder 50 is movably installed on the threaded tube 48. An opening 52 is opened on the extraction tube 51. The opening 52 cooperates with the one-way hole 21. A motor housing 5 is fixed to the top of the water tank 2. A water pump is fixed inside the motor housing 5. A suction pipe 6 and a drain pipe are fixed to the water pump. One end of the suction pipe 6 is fixed inside the water tank 2. A fixing plate 23 is welded inside the barrel 13. The fixing plate 23 has a fixing hole. The exhaust assembly 28 is movably installed inside the fixing hole. In use, the water pump generates suction, which pressurizes the liquid inside the water tank 2 and draws it into the inlet pipe 26. The water inside the inlet pipe 26 enters the water storage chamber inside the rotating disc 24. The water chamber is connected to the atomizing nozzle 36. The internal water pressure pushes the liquid outward through the atomizing nozzle 36. The atomizing nozzle 36 is distributed in a circle on the side of the fixed cylinder 30. The gas discharged inside the fixed cylinder 30 is thoroughly purified and filtered again by the atomized liquid. In addition, after the extraction pipe 51 is installed on the fixed pipe 20, there is a gap between the extraction pipe 51 and the fixed pipe 20. Later, the liquid at the bottom is indirectly introduced into the space between the fixed pipe 20 and the extraction pipe 51 through the gap, and the liquid inside the purification tank 10 is completely discharged through the opening 52 at the bottom.
[0023] In this embodiment, a rotating disk 24 is rotatably mounted inside the barrel 13. A sealing seat 25 is movably mounted on the rotating disk 24. The sealing seat 25 is rotatably mounted on the rotating disk 24 via a sealing convex ring. A water inlet pipe 26 is fixed to the sealing seat 25 and is connected to a drain pipe. A filter assembly 27 is fixed on the rotating disk 24. The filter assembly 27 includes a fixed cylinder 30, which is fixedly mounted on the rotating disk 24. A filter plate 34 is fixedly mounted on the fixed cylinder 30. A reinforcing seat 35 is fixed to the side of the fixed cylinder 30. An atomizing nozzle 36 is fixedly mounted on the reinforcing seat 35. The atomizing nozzle 36 is installed inside the rotating disk 24 via a connecting pipe. The rotating disk 24 has a cavity inside, which is a water storage cavity. The rotating disk 24 has a mounting hole 32, and a limiting groove 33 is formed on the side of the mounting hole 32. A rotating column 31 is fixed inside the mounting hole 32, and a limiting block is fixed on the rotating column 31. The limiting block is movably installed inside the limiting groove 33. The rotating column 31 is movably installed on the fixed disk 23, and one end of the rotating column 31 is fixed to the drive motor 15. In use, the sealing seat 25 is convex in shape and installed on the side of the rotating disk 24. After the protruding sealing seat 25 is installed on the rotating disk 24 through the rotating sealing ring, the water inlet pipe 26 provides a support point for the sealing seat 25. Later, when the rotating disk 24 rotates, the centrifugal force generated by the rotating disk 24 facilitates the rapid removal of residual water on the filter plate 34. At the same time, the rotating disk 24 generates turbulence through the fixed cylinder 30 while rotating, and the inside of the barrel 13 is dried under the action of turbulence. After the rotating disk 24 rotates, it returns to its original position. The infrared sensor on the fixed disk 23 senses the position of the rotating disk 24, and the drive motor 15 drives the rotating disk 24 to rotate. After the rotating disc 24 returns to its original position, it facilitates the re-entry of the movable cylinder 37 into the fixed cylinder 30. The movable cylinder 37 moves under the pressure of the exhaust gas, and the movement of the movable cylinder 37 achieves filtration at the filtration points based on the thrust of the air pressure. After the movable cylinder 37 is fully inserted into the fixed cylinder 30 under the push of the air pressure, the exhaust port 41 first contacts half of the filter plate 34 for filtration. The gas filtered by the filter plate 34 undergoes secondary adsorption filtration in the water mist sprayed from the atomizing nozzle 36, which reduces the subsequent temperature. The exhaust gas pressure causes the movable cylinder 37 to retract by half its distance, and the exhaust port 41 moves to the other half of the filter plate 34 for filtration. When the movable cylinder 37 moves, the silicone ring 40 scrapes and cleans the inner wall of the filter plate 34. Later, the air intake on one side is closed. When the movable cylinder 37 returns to its original position, the silicone ring 40 pushes the impurities inside out of the fixed cylinder 30 and cleans them completely. When the movable cylinder 37 on one side stops taking in air, the other side of the barrel 13 can continue to take in air, so as to treat the exhaust gas without stopping the machine.
[0024] In this embodiment, an exhaust pipe 4 is fixed to one end of the filter box 3. A filter adsorption plate, including an activated carbon plate and a moisture-absorbing plate, is fixedly installed inside the filter box 3. The activated carbon plate and the moisture-absorbing plate are fixedly installed on the side of the guide tube 45. A drain pipe is fixed to one end of the extraction tube 44. A sliding groove is formed on the inner wall of the fixing hole. The slider 42 is movably installed inside the sliding groove. A support mechanism 43 is fixed inside the sliding groove, and one end of the support mechanism 43 is fixed to the slider 42. A drain pipe is fixedly installed at the bottom of the barrel 13, and a control box 17 is fixedly installed on the side of the fixed base 1. The control box 17 is fixedly installed on the side of the bracket 16. The support mechanism 43 is a support spring. After the support spring is compressed, it generates a rebound force. The rebound force pushes the movable cylinder 37 to return to its original position. In the later stage, when no exhaust gas enters, the support mechanism 43 pushes the movable cylinder 37 to always be installed inside the fixed plate 23. The fixing ring 39 and the silicone ring 40 seal the fixing hole at the fixed plate 23, thereby effectively preventing water mist from moving from the fixing hole to both ends of the barrel 13 and causing an impact.
[0025] Working Principle: During use, an external pipe is installed on the air inlet pipe 14. Exhaust gas enters the interior of the barrel 13 through the air inlet pipe 14. The pressure of the exhaust gas is adjusted by external equipment, and the position of the movable cylinder 37 is adjusted accordingly. The movable cylinder 37 is moved by the air pressure of the exhaust gas. The movement of the movable cylinder 37 achieves filtration at the filtration point based on the thrust of the air pressure. After the movable cylinder 37 is fully inserted into the fixed cylinder 30 under the thrust of the air pressure, the air outlet 41 first contacts half of the filter plate 34 for filtration. The water pump inside the motor box 5 is started, and the water pump generates suction. The suction pressurizes the liquid inside the water tank 2 and enters the interior of the water inlet pipe 26. The water inside the water inlet pipe 26 enters the water storage chamber inside the rotating disc 24. The water storage chamber is connected to the atomizing nozzle 36. The internal water pressure pushes the water inlet nozzle into the water storage chamber. The liquid is sprayed outward through the atomizing nozzle 36, which is distributed in a circular pattern on the side of the fixed cylinder 30. The gas discharged inside the fixed cylinder 30 undergoes comprehensive re-purification and filtration through the atomized liquid. The gas filtered by the filter plate 34 undergoes secondary adsorption and filtration by the water mist sprayed from the atomizing nozzle 36. Later, the exhaust gas pressure is reduced, causing the movable cylinder 37 to retract by half. The air outlet 41 moves to the other half of the filter plate 34 for filtration. When the movable cylinder 37 moves, the silicone ring 40 scrapes and cleans the inner wall of the filter plate 34. Later, the air intake on one side is closed. As the movable cylinder 37 returns to its original position, the silicone ring 40 pushes the impurities inside out of the fixed cylinder 30 for complete cleaning. When the movable cylinder 37 on one side stops intake, the other side of the barrel 13 can continue to intake air, thus treating the exhaust gas without stopping the machine. After initial purification, the gas enters the connecting tank 7 through the connecting box 29. The exhaust gas inside the connecting tank 7 enters the diversion pipe 8 through the connecting pipe 18. The gas in the diversion pipe 8 enters the fixed pipe 20. The pressure of the gas pushes the rubber diaphragm inside the one-way hole 21 to open, and the gas is sprayed into the purification tank 10 through the one-way hole 21. The gas tumbles in the liquid inside the purification tank 10 for secondary adsorption. The top opening 52 is always installed at the top of the liquid surface. The extraction pipe 51 generates suction, which draws the gas from the top of the liquid surface in the purification tank 10 outwards. After being drawn out through the extraction pipe 51, the exhaust gas extracted by the extraction cylinder 44 enters the interior of the filter box 3 through the guide cylinder 45. The exhaust gas discharged from the guide cylinder 45 is adsorbed and filtered by the activated carbon adsorption plate and the moisture absorption plate inside the filter box 3. Later, the air inlet channel of the guide cylinder 45 can be closed. When the extraction cylinder 44 stops intake, the sludge suction pipe at one end of the extraction cylinder 44 is started. The sludge suction pipe is connected to an external suction device, and the threaded cylinder 49 is rotated and moved downward. After the threaded cylinder 49 moves downward, the right-angle cylinder 50 loses its upward thrust and moves downward by its own gravity. After downward movement, the extraction tube 51 moves onto the fixed tube 20, and the bottom opening 52 on the extraction tube 51 is fully inserted into the liquid space. A gap exists between the extraction tube 51 and the fixed tube 20, allowing liquid to enter between them. The suction generated by the extraction tube 51 draws the liquid out of the purification tank 10 for replacement. During adsorption, the right-angle cylinder 50 is pushed up and down by the threaded tube 48. The up-and-down movement of the right-angle cylinder 50 adjusts the position of the opening 52 on the extraction tube 51 inside the purification tank 10. Later, the extraction tube 51 is removed from the purification tank 10. The interior of the filter 10 is moved upwards. After being moved out, the filter 10 loses its fixed point and can be quickly removed from the mounting base 9. After removal, it is cleaned. Later, when the rotating disk 24 rotates, the centrifugal force generated by the rotating disk 24 facilitates the quick removal of residual water on the filter plate 34. At the same time, the rotating disk 24 generates turbulence through the fixed cylinder 30 while rotating. Under the action of turbulence, the interior of the barrel 13 is dried. After rotating, the rotating disk 24 returns to its original position. The infrared sensor on the fixed disk 23 senses the position of the rotating disk 24 and drives the rotating disk 24 to return to its original position through the drive motor 15.
