Description

Technical Field

[0001] This invention belongs to the field of flue gas filtration technology, specifically a catalytic filter tube device for treating flue gas pollutants. Background Technology

[0002] Flue gas contains various chemical substances, such as heavy metals, nitrogen oxides, and sulfides. These substances, at certain concentrations, can pollute the environment. Without appropriate treatment, indiscriminate emission of these gases can severely impact and harm the environment and human health. Therefore, cooled flue gas typically requires further purification to remove most of the harmful substances. Catalytic filtration is a common flue gas treatment method.

[0003] For example, Chinese patent CN217312463U discloses a flue gas duct in a denitrification catalyst device, which includes a flue gas duct body. An inlet pipe is provided at the bottom of one side of the flue gas duct body, and an outlet pipe is provided at the top of the other side of the flue gas duct body. A guide plate is fixedly connected to the bottom of the flue gas duct body, and a collection chamber is detachably connected to the bottom of the guide plate. An anti-overflow plate is fixedly connected to the inner wall of the guide plate. A motor is fixedly installed at the top of the flue gas duct body. A rotating shaft is provided inside the flue gas duct body. The top of the rotating shaft is fixedly connected to the output shaft of the motor. From bottom to top, a coarse filter plate, a fine filter plate, a high-efficiency filter plate, an activated carbon filter plate, and a cover plate are connected to the outer surface of the rotating shaft through bearings.

[0004] Although it can prevent dust particles and harmful gases generated during the calcination process from harming workers and polluting the environment, workers found during use that because the flue gas contains a large number of particles that adhere to the holes of the coarse and fine filter plates, the brush bristles can only clean the particles on the surface of the coarse and fine filter plates, causing blockage and affecting the filtration effect.

[0005] Dust from the upper layer falls into the lower layer, affecting the filtration effect.

[0006] Therefore, the present invention provides a catalytic filter tube device for treating flue gas pollutants. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

The bristles of the cleaning brush are in contact with the bottom surface of the filter plate.

[0011] The striking hammer is elastically set on the outer wall of the control shaft, and the baffle plate is fixedly installed on the upper end face of the filter plate. The elastic force on the striking hammer causes the outer wall of the striking hammer to tend to fit against the upper end face of the filter plate in real time. Rotating the control shaft drives the striking hammer to rotate along the axis of the control shaft.

[0012] The drive mechanism includes a drive motor and a transmission shaft fixedly mounted on the support plate. The transmission shaft is connected to the power transmission shaft of the drive motor. The drive motor controls the rotation of the control shaft through the transmission shaft. After the accommodating cylinder and the mounting cylinder are assembled, the control shaft is connected to the transmission shaft, thereby driving the control shaft to rotate through the drive motor to clean the filter plate.

[0013] Preferably, a discharge pipe is fixedly installed on the outer wall of the container, with one end of the discharge pipe extending into the inner cavity of the container and located on the upper side of the catalytic layer, so that the flue gas can be fully filtered and discharged through the discharge pipe.

[0014] A feed pipe is fixedly installed on the outer wall of the support chassis for flue gas to enter. A guide plate is fixedly installed on the inner wall of the support chassis. Dust particles falling from the filter plate fall onto the upper surface of the inclined guide plate. A sealing plate is detachably installed on the outer wall of the support chassis.

[0016] Preferably, the inner wall of the mounting cylinder has a cavity for storing coolant, and a connecting pipe is fixedly installed on the upper end face of the mounting cylinder. The bottom of the mounting cylinder has a through hole for inserting the connecting pipe. When the two mounting cylinders are assembled, the two cavities are connected through the connecting pipe, so that the outer wall of the mounting cylinder is fixedly installed with a liquid delivery pipe. The liquid delivery pipe is strongly connected to the external coolant storage through a circulation pump. One end of the liquid delivery pipe is detachably fitted with a sealing plug, which is connected to the liquid delivery pipe through internal and external thread engagement.

[0017] A bearing ring is fixedly installed on the radial inner wall of the mounting cylinder, and a support ring is fixedly installed on the radial outer wall of the filter plate. The support ring supports the bearing ring to achieve the initial fixation of the filter plate.

[0018] Preferably, a plug rod is fixedly installed on the upper end face of the bearing ring, and a notch is opened on the outer wall of the plug rod. A guide frame is fixedly installed on the upper end face of the support ring, and a locking tongue for plugging into the plug rod is slidably installed on the inner wall of the guide frame. A through hole for the plug rod to pass through is opened on the outer wall of the support ring. The plug rod is plugged into the through hole, and the sliding locking tongue is plugged into the notch on the outer wall of the plug rod to fix the filter plate.

[0019] A top pressure ball is fixedly installed on the upper end face of the support ring, and an adjusting rod is fixedly installed on the upper end face of the latch. A groove adapted to the top pressure ball is opened on the bottom surface of the latch. The latch is slid until the top pressure ball is located in the groove, thereby fixing the latch.

[0020] Preferably, a connecting cylinder is fixedly installed on the bottom surface of the control shaft, and a connecting shaft is elastically installed in the inner cavity of the connecting cylinder. A plug-in block is fixedly installed at the bottom end of the connecting shaft through the bottom surface of the connecting cylinder. A plug-in groove for the plug-in block to be inserted is opened on the upper end surface of the control shaft. After the two mounting cylinders are assembled, the two control shafts are controlled to rotate synchronously by inserting the plug-in block into the plug-in groove.

[0021] Preferably, a control spring is provided on the outer wall of the connecting shaft. One end of the control spring is fixedly connected to the outer wall of the connecting shaft, and the other end of the control spring is fixedly connected to the inner wall of the connecting cylinder. The spring force of the control spring pushes the connecting shaft in real time, so that the plug block has a tendency to plug into the plug slot in real time.

[0022] Preferably, a support block is fixedly installed on the radial outer wall of the control shaft, and an installation plate is slidably installed on the inner wall of the support block. A pressing shaft for pressing the cleaning brush is fixedly installed on the upper end of the installation plate. The installation plate is slidable until the pressing shaft is inserted into the groove, and at the same time, the bristles of the cleaning brush are in contact with the bottom surface of the filter plate to realize the installation of the cleaning brush. An adjusting shaft is rotatably installed on the bottom surface of the installation plate. The outer wall of the adjusting shaft is connected to the support block through internal and external thread engagement. After the bristles wear, the adjusting shaft is rotated until the pressing shaft is separated from the cleaning brush. At this time, the cleaning brush can be removed and replaced, which is convenient to operate.

[0023] The beneficial effects of this invention are as follows: 1. This invention comprises a striking hammer, a connecting plate, and an elastic plate. The connecting plate is fixedly installed on the radial outer wall of the control shaft. The elastic plate enables the striking hammer to be elastically connected to the connecting plate. The striking hammer tends to adhere to the filter plate in real time. A baffle plate is provided on the outer wall of the filter plate. As the striking hammer rotates along the axis of the control shaft, it is lifted by the baffle plate. As the control shaft rotates, the striking hammer strikes the upper surface of the filter plate. This vibration controls the dust adhering to the holes in the filter plate and the dust adhering to the upper surface of the filter plate to fall off, thereby collecting dust particles and improving the cleaning efficiency of the filter plate. 2. This invention features an assemblable mounting cylinder with an inner cavity for receiving the coolant. A connecting pipe is installed at the shaft end of the mounting cylinder, communicating with the receiving cavity. A liquid delivery pipe is fixedly installed on the outer wall of the mounting cylinder. A circulating pump controls the circulation of coolant within the receiving cavity, thereby absorbing heat energy from the mounting cylinder and reducing the temperature of the outer wall. Furthermore, by recovering heat from the coolant, the waste heat energy in the flue gas can be utilized, resulting in energy conservation and environmental protection. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] Example 1: As Figures 1 to 5 As shown in the embodiment of the present invention, a catalytic filter tube device for treating flue gas pollutants includes a supporting chassis 1, a mounting cylinder 2, a receiving cylinder 3, a supporting plate 4, a driving mechanism, a filtering mechanism, and a cleaning mechanism. The mounting cylinder 2 is detachably mounted on the upper end face of the supporting chassis 1. A threaded ring is provided on the upper end face of the mounting cylinder 2, and the mounting cylinder 2 is connected to the upper end face of the supporting chassis 1 through the threaded ring.

[0029] The receiving cylinder 3 is detachably installed on the upper end face of the mounting cylinder 2. A threaded ring is provided on the bottom surface of the receiving cylinder 3. The receiving cylinder 3 is connected to the mounting cylinder 2 through the threaded ring. The mounting support plate 4 is fixedly installed on the upper end face of the receiving cylinder 3.

[0030] The filtration mechanism includes a filter plate 22 and a catalyst layer 9. The filter plate 22 is detachably installed on the inner wall of the mounting cylinder 2. The filter plate 22 is a common filter screen used for filtering particulate matter in smoke. The catalyst layer 9 is fixedly installed in the inner cavity of the accommodating cylinder 3. The catalyst layer 9 is a catalyst layer used for catalytic filtration of smoke.

[0031] The cleaning mechanism includes a control shaft 17, a cleaning brush 23, a hammer 19, and a baffle plate 15. The control shaft 17 is rotatably mounted at the center of the axial end of the filter plate 22, and the control shaft 17 can rotate along its own axis.

[0032] The bristles of the cleaning brush 23 are in contact with the bottom surface of the filter plate 22. The cleaning brush 23 is detachably mounted on the outer wall of the control shaft 17. Rotating the control shaft 17 drives the cleaning brush 23 to rotate, thereby cleaning the smoke particles attached to the surface of the filter plate 22.

[0033] The striking hammer 19 is elastically set on the outer wall of the control shaft 17. The baffle plate 15 is fixedly installed on the upper end face of the filter plate 22. The outer wall of the baffle plate 15 is set in an arc shape. The elastic force received by the striking hammer 19 controls the outer wall of the striking hammer 19 to have a tendency to fit against the upper end face of the filter plate 22 in real time. Rotating the control shaft 17 drives the striking hammer 19 to rotate along the axis of the control shaft 17.

[0034] As the striking hammer 19 rotates along the axis of the control shaft 17, it contacts the baffle plate 15 and is lifted up by the baffle plate 15. As the control shaft 17 rotates, the striking hammer 19 strikes the upper surface of the filter plate 22, thereby controlling the dust adhering to the holes of the filter plate 22 and the dust adhering to the upper surface of the filter plate 22 to fall off through vibration. The fallen dust particles fall into the inner cavity of the supporting chassis 1, realizing the collection of dust particles and improving the cleaning efficiency of the filter plate 22.

[0035] The drive mechanism includes a drive motor 5 and a transmission shaft 10 fixedly mounted on the support plate 4. The output shaft of the drive motor 5 passes through the support plate 4, and a sealed bearing is provided at the connection. The transmission shaft 10 is connected to the power transmission shaft of the drive motor 5.

[0036] The drive motor 5 controls the rotation of the control shaft 17 through the transmission shaft 10. After the accommodating cylinder 3 and the mounting cylinder 2 are assembled, the control shaft 17 is connected to the transmission shaft 10, thereby driving the control shaft 17 to rotate through the drive motor 5, thus cleaning the filter plate 22.

[0037] A discharge pipe 6 is fixedly installed on the outer wall of the container cylinder 3. One end of the discharge pipe 6 extends into the inner cavity of the container cylinder 3 and is located on the upper side of the catalytic layer 9 so that the flue gas can be fully filtered and discharged through the discharge pipe 6.

[0038] A feed pipe 7 is fixedly installed on the outer wall of the support chassis 1. The feed pipe 7 is used for flue gas to enter. A guide plate 11 is fixedly installed on the inner wall of the support chassis 1. Dust particles falling from the filter plate 22 fall onto the upper surface of the inclined guide plate 11.

[0039] A sealing plate 8 is detachably installed on the outer wall of the bearing chassis 1. The sealing plate 8 is connected to the outer wall of the bearing chassis 1 by bolts. Sealing rubber is provided at the contact position between the sealing plate 8 and the bearing chassis 1. The sealing plate 8 is located at the lowest position of the guide plate 11. The sealing plate 8 can be removed to facilitate the cleaning and removal of dust particles.

[0040] A connecting plate 18 is fixedly installed on the radial outer wall of the control shaft 17. An elastic plate 20 is fixedly installed on the side wall of the connecting plate 18. The elastic plate 20 is a common elastic copper plate. The end of the elastic plate 20 away from the connecting plate 18 is fixedly connected to the outer wall of the striking hammer 19. The striking hammer 19 and the control shaft 17 are elastically connected through the cooperation of the elastic plate 20 and the connecting plate 18. Rotating the control shaft 17 drives the connecting plate 18 and the striking hammer 19 to rotate through the connecting plate 18.

[0041] The inner wall of the mounting cylinder 2 is provided with a cavity 12 for storing coolant. A connecting pipe 16 is fixedly installed on the upper end face of the mounting cylinder 2. The bottom of the mounting cylinder 2 is provided with a through hole for the connecting pipe 16 to be inserted. When the two mounting cylinders 2 are assembled, the two cavities 12 are connected through the connecting pipe 16.

[0042] An infusion pipe 13 is fixedly installed on the outer wall of the mounting cylinder 2. Each mounting cylinder 2 has at least two infusion pipes 13. The infusion pipe 13 is strongly connected to an external coolant storage via a circulation pump. A sealing plug 14 is detachably installed at one end of the infusion pipe 13. The sealing plug 14 is connected to the infusion pipe 13 via internal and external thread engagement, and a sealing ring for pipe sealing is required at the connection position.

[0043] Flue gas is often accompanied by high temperature. As the flue gas is introduced, the temperature of the inner cavity of the mounting cylinder 2 gradually increases. In order to prevent burns, the coolant is controlled by the circulating pump to circulate in the inner cavity of the accommodating cavity 12, thereby absorbing the heat energy in the mounting cylinder 2 and reducing the temperature of the outer wall of the mounting cylinder 2. In addition, by recovering the heat in the coolant, the waste heat energy in the flue gas can be utilized, which is economical and environmentally friendly.

[0044] A bearing ring 37 is fixedly installed on the radial inner wall of the mounting cylinder 2, and a support ring 21 is fixedly installed on the radial outer wall of the filter plate 22. The support ring 21 supports the bearing ring 37 to achieve the initial fixation of the filter plate 22.

[0045] In this embodiment, after multiple mounting cylinders 2 are assembled, the filter aperture of the filter plate 22 in each mounting cylinder 2 needs to decrease with height, so that the dust particles cleaned on the uppermost filter plate 22 can fall smoothly into the inner cavity of the support chassis 1 located at the bottom.

[0046] Example 2: Figures 6 to 9 As shown in Example 1, another embodiment of the present invention is as follows: A plug rod 32 is fixedly installed on the upper end face of the bearing ring 37. The outer wall of the plug rod 32 has a notch. A guide frame 29 is fixedly installed on the upper end face of the support ring 21. A locking tongue 30 for plugging into the plug rod 32 is slidably installed on the inner wall of the guide frame 29. A through hole for the plug rod 32 to pass through is opened on the outer wall of the support ring 21. The plug rod 32 is plugged into the through hole, and the sliding locking tongue 30 is plugged into the notch on the outer wall of the plug rod 32 to fix the filter plate 22.

[0047] Slide the locking tongue 30 in the opposite direction until the locking tongue 30 separates from the insertion rod 32. At this time, the support ring 21 can be removed from the inner cavity of the mounting cylinder 2 to disassemble the filter plate 22, so as to facilitate the disassembly and replacement of the filter plate 22.

[0048] A top pressure ball 38 is fixedly installed on the upper end face of the support ring 21, and an adjusting rod 31 is fixedly installed on the upper end face of the locking tongue 30. A groove adapted to the top pressure ball 38 is opened on the bottom surface of the locking tongue 30. The locking tongue 30 is slid until the top pressure ball 38 is located in the groove, thereby fixing the locking tongue 30.

[0049] A connecting cylinder 24 is fixedly installed on the bottom surface of the control shaft 17. A connecting shaft 25 is elastically installed in the inner cavity of the connecting cylinder 24. The connecting shaft 25 is a common rectangular rod. Rotating the connecting cylinder 24 can control the connecting shaft 25 to rotate synchronously. A plug-in block 28 is fixedly installed on the bottom end of the connecting shaft 25 through the bottom surface of the connecting cylinder 24. A plug-in groove 27 is opened on the upper end surface of the control shaft 17 for the plug-in block 28 to be inserted. After the two mounting cylinders 2 are assembled, the plug-in block 28 is inserted into the plug-in groove 27 to control the two control shafts 17 to rotate synchronously.

[0050] To facilitate the rotation of the control shaft 17 by the drive shaft 10, a connecting cylinder 24 is provided on the bottom surface of the control shaft 17. The connection is achieved by inserting the plug 28 on the bottom surface of the connecting cylinder 24 into the plug slot 27. After assembly, the drive motor 5 synchronously controls the rotation of multiple control shafts 17.

[0051] A control spring 26 is provided on the outer wall of the connecting shaft 25. One end of the control spring 26 is fixedly connected to the outer wall of the connecting shaft 25, and the other end of the control spring 26 is fixedly connected to the inner wall of the connecting cylinder 24. The elastic force of the control spring 26 pushes the connecting shaft 25 in real time, so that the plug block 28 tends to plug into the plug slot 27 in real time. Thus, during the assembly process, even if the plug block 28 is not plugged into the plug slot 27 in the initial state, the drive motor 5 can drive the transmission shaft 10 to rotate and adjust until the plug block 28 falls into the inner cavity of the plug slot 27, reducing the difficulty of operation.

[0052] A support block 33 is fixedly installed on the radial outer wall of the control shaft 17. An installation plate 35 is slidably installed on the inner wall of the support block 33. A pressing shaft 34 for pressing the cleaning brush 23 is fixedly installed on the upper end of the installation plate 35. The back of the cleaning brush 23 is provided with a groove for the pressing shaft 34 to be inserted. The installation plate 35 is slidable until the pressing shaft 34 is inserted into the groove. At the same time, the bristles of the cleaning brush 23 are in contact with the bottom surface of the filter plate 22, thus realizing the installation of the cleaning brush 23. An adjusting shaft 36 is rotatably installed on the bottom surface of the installation plate 35. The outer wall of the adjusting shaft 36 is connected to the support block 33 through internal and external thread engagement. After the bristles wear, the adjusting shaft 36 is rotated until the pressing shaft 34 is separated from the cleaning brush 23. At this time, the cleaning brush 23 can be removed and replaced, which is convenient to operate.
