Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, in particular to a high-concentration waste gas treatment device. Background Art

[0002] The high-concentration organic waste gas treatment device is an auxiliary device used to treat high-concentration organic waste gas generated in chemical production and spraying processes to avoid pollution to the atmospheric environment. It has been widely used in the field of environmental protection.

[0003] A search revealed a Chinese patent with the publication number CN116371112B, which discloses a high-concentration, high-temperature waste gas treatment device for a chemical reactor and a method for using the same. The device relates to the field of waste gas treatment and includes a base, a reactor and a purification unit fixedly connected to the top of the base, and a delivery pump fixedly connected to the outer wall of the reactor. The device is characterized by also including a waste heat recovery unit fixedly connected to the top of the base and a heat absorption unit connected to the side wall of the purification unit. The waste heat recovery unit includes a water tank, a coiled pipe extending through the bottom plate of the water tank, an installation chamber fixedly connected to the outer wall of the coiled pipe, and a first installation member inserted into the interior of the installation chamber to absorb waste gas heat. This invention relates to a high-concentration, high-temperature waste gas treatment device for a chemical reactor and a method for using the same. By staggering the first and second inclined plates when delivering waste gas to the installation chamber, the device can prolong the waste gas's circulation time within the installation chamber, thereby better delivering heat to the installation chamber.

[0004] In the above-mentioned existing technical solution, the heat in the exhaust gas is recovered and utilized by sending the exhaust gas into the waste heat recovery unit, and then the exhaust gas is sent to the purification unit, and the aqueous solution dissolves the water-soluble substances in the exhaust gas. After that, the exhaust gas will pass through the drying layer and the activated carbon adsorption layer in sequence to complete the purification of the exhaust gas. However, in actual use, the particulate impurities in the exhaust gas will block the pores of the drying layer and the activated carbon adsorption layer, causing the air permeability of the two-layer structure to gradually deteriorate, thereby reducing the exhaust gas treatment efficiency.

[0033] Compared with the prior art, the present invention has the following significant advantages:

[0034] First, the present invention introduces exhaust gas into the interior of the treatment box through an air inlet pipe, and restricts the inner filter belt and the outer filter belt through the groove, so that the inner filter belt and the outer filter belt are closely fitted, and the transverse grooves on the inner filter belt and the longitudinal grooves on the outer filter belt are staggered with each other to form a mesh to filter the exhaust gas. As the inner filter belt and the outer filter belt continue to filter the exhaust gas, impurities in the exhaust gas will block the pores on the inner filter belt and the outer filter belt, resulting in a worsening filtering effect. As more and more exhaust gas is stored inside the treatment box, the air pressure inside the treatment box also increases until the trigger component starts the drive motor to start working, and the drive motor drives the drive disk to rotate. Under the cooperation of the driven disk and the transmission belt, the drive roller is driven to rotate, so that the inner filter belt and the outer filter belt sleeved on the side wall of the drive roller are rotated, and the parts of the inner filter belt and the outer filter belt located inside the treatment box are replaced, thereby ensuring the filtering efficiency of the inner filter belt and the outer filter belt for the exhaust gas; and solves the problem of low treatment efficiency of the existing exhaust gas treatment device.

[0035] Secondly, the present invention fixes the extension spring to the side wall of the outer filter belt. When the inner filter belt is separated from the interior of the treatment box, the elasticity of the extension spring pushes the outer filter belt to expand outward, so that there is a gap between the outer filter belt and the inner filter belt, thereby increasing the gap between the inner filter belt and the outer filter belt, making it easier for impurities on the side walls of the inner filter belt and the outer filter belt to fall off. By aligning the clamping block and the clamping groove with each other, the clamping block can be clamped inside the clamping groove, making it easier for the outer filter belt to move synchronously with the inner filter belt.

[0036] Thirdly, the present invention sends the gas output by the air pump into the interior of the positioning tube through the connecting pipe, and outputs it outwards through the connecting groove and the ventilation groove, fits with the inner side wall of the transmission roller through the stabilizing frame, and with the cooperation of the exhaust groove, limits the range of the air inside the transmission roller to be blown out outwards, blows off the impurities attached to the side walls of the inner filter belt and the outer filter belt, and facilitates the cleaning of the inner filter belt and the outer filter belt.

[0037] Fourthly, the present invention makes the air baffle fit the side wall of the outer filter belt. When the air inside the transmission roller is blown out through the exhaust groove, it will directly blow on the side wall of the air baffle, causing the air baffle to rotate around the fixed rotating shaft. When the outer filter belt is aligned with the exhaust groove, the air baffle is no longer blown by the air. It rotates around the fixed rotating shaft under the influence of gravity and hits the side wall of the outer filter belt, causing the inner filter belt and the outer filter belt to vibrate, making it easier for impurities on the side walls of the inner filter belt and the outer filter belt to fall off. The impurities on the side walls of the inner filter belt and the outer filter belt are collected by a collecting drawer. By pulling out the collecting drawer, the impurities can be processed centrally.

[0038] Fifth: The present invention aligns the pressing roller with the side wall of the through groove so that the pressing roller can squeeze the side wall of the outer filter belt and guide the outer filter belt, thereby facilitating the outer filter belt to fit the side wall of the inner filter belt and facilitate the outer filter belt to enter the interior of the through groove.

[0052] The present invention is described in detail below, clearly and completely describing the technical solutions in the embodiments of the present invention.

A filter assembly is provided on the outside of the treatment box 1, and the filter assembly includes an inner filter belt 31, a receiving groove 37 and a clamping block 35;

[0055] The inner filter belt 31 passes through the interior of the groove 9. The outer filter belt 33 is covered on the outer surface of the inner filter belt 31. The side wall of the inner filter belt 31 is provided with a plurality of equally spaced transverse grooves 32. The side wall of the outer filter belt 33 is provided with a plurality of equally spaced longitudinal grooves 34.

[0056] There are two receiving grooves 37, both of which are opened on the outer wall of the inner filter belt 31. A plurality of extension springs 38 are fixedly installed on the inner wall of the receiving groove 37 at equal intervals. The end of the extension spring 38 away from the inner filter belt 31 is fixedly connected to the inner wall of the outer filter belt 33. By fixing the extension spring 38 to the side wall of the outer filter belt 33, when the inner filter belt 31 is separated from the interior of the treatment box 1, the elasticity of the extension spring 38 pushes the outer filter belt 33 to expand outward, so that a gap exists between the outer filter belt 33 and the inner filter belt 31, thereby increasing the gap between the inner filter belt 31 and the outer filter belt 33, and facilitating the shedding of impurities on the side walls of the inner filter belt 31 and the outer filter belt 33.

[0057] There are multiple clamping blocks 35, which are fixedly installed on the inner side wall of the outer filter belt 33 at equal distances. A plurality of clamping grooves 36 are opened on the side wall of the inner filter belt 31, and the plurality of clamping grooves 36 are aligned with the plurality of clamping blocks 35 respectively.

[0058] A driving assembly is provided outside the processing box 1, and the driving assembly includes a fixing frame 41, a transmission roller 44 and a driving disc 43;

[0059] The fixing frame 41 is fixedly mounted on the outer wall of the processing box 1, and the driving motor 42 is fixedly mounted on the top wall of the fixing frame 41;

[0060] There are two transmission rollers 44, both of which are located inside the inner filter belt 31. A positioning tube 48 is provided inside the transmission roller 44. The positioning tube 48 is rotatably mounted inside the transmission roller 44 through a bearing. Support frames 45 are provided on both sides of the transmission roller 44. The positioning tube 48 is fixedly mounted on the side wall of the support frame 45 away from the fixing frame 41.

[0061] The driving disc 43 is fixedly mounted on the output shaft of the driving motor 42, and the ends of the two driving rollers 44 close to the driving motor 42 are fixedly mounted with driven discs 46, and the driven discs 46 are rotatably mounted on the side walls of the adjacent support frames 45. The side walls of the two driven discs 46 are sleeved with transmission belts 47, and the ends of the transmission belts 47 close to the driving motor 42 are sleeved on the side walls of the driving disc 43; the position of the driving rollers 44 is supported by the support frames 45 and the positioning tubes 48 to ensure the stable position of the driving rollers 44, and at the same time, the driven discs 46 are rotatably mounted on the side walls of the support frames 45 and fixedly connected to the driving rollers 44, so that the support frames 45 can ensure the stable position of the driven discs 46, and at the same time facilitate the driven discs 46 to drive the driving rollers 44 to rotate;

[0062] A trigger assembly is provided at the bottom of the air inlet pipe 2, and the trigger assembly includes a fixing frame 71, a sealing disc 73 and a positioning plate 77;

[0063] The fixing frame 71 is arranged at the bottom of the air intake pipe 2 , and a connecting pipe 72 is fixedly mounted on the top wall of the fixing frame 71 , and the connecting pipe 72 is connected to the interior of the air intake pipe 2 ;

[0064] The sealing disc 73 is slidably mounted inside the connecting pipe 72. A stabilizing disc 74 is fixedly mounted on the inner side wall of the connecting pipe 72. A sealing post 75 is slidably passed through the inner side of the stabilizing disc 74. The sealing post 75 is fixedly mounted on the bottom wall of the sealing disc 73. A return spring 76 is sleeved on the side wall of the sealing post 75. The two ends of the return spring 76 are respectively fixedly connected to the side wall near the sealing disc 73 and the stabilizing disc 74.

[0065] The positioning plate 77 is fixedly mounted on the inner wall of the fixed frame 71, and a touch switch 78 is fixedly mounted on the top wall of the positioning plate 77. The touch switch 78 is aligned with the sealing column 75, and the touch switch 78 is electrically connected to the drive motor 42; the exhaust gas is introduced into the interior of the treatment box 1 through the air inlet pipe 2, and the inner filter belt 31 and the outer filter belt 33 are restricted by the groove 9, so that the inner filter belt 31 and the outer filter belt 33 are tightly fitted, and the transverse grooves 32 on the inner filter belt 31 and the longitudinal grooves 34 on the outer filter belt 33 are staggered to form a mesh to filter the exhaust gas. As the inner filter belt 31 and the outer filter belt 33 continue to filter the exhaust gas, impurities in the exhaust gas will block the pores on the inner filter belt 31 and the outer filter belt 33, resulting in a worsening of the filtering effect. As more and more waste gas is stored, the air pressure inside the treatment box 1 also becomes higher. The sealing disk 73 moves downward as the air pressure inside the treatment box 1 becomes higher, and the sealing column 75 moves downward as the sealing disk 73 moves and contacts the touch switch 78, so that the drive motor 42 starts to work. The drive disk 43 is driven to rotate by the operation of the drive motor 42. With the cooperation of the driven disk 46 and the transmission belt 47, the drive roller 44 is driven to rotate, so that the inner filter belt 31 sleeved on the side wall of the drive roller 44 is rotated, and the clamping block 35 is clamped in the inside of the clamping groove 36, so the outer filter belt 33 can rotate synchronously with the inner filter belt 31, and the parts of the inner filter belt 31 and the outer filter belt 33 located inside the treatment box 1 are replaced to ensure the filtering efficiency of the inner filter belt 31 and the outer filter belt 33 for the waste gas.

[0066] like Figure 1-Figure 3 As shown, in one embodiment, four pressing assemblies are provided on the side wall of the processing box 1, and the pressing assemblies include a mounting frame 81 and a pressing roller 82;

[0067] There are two mounting brackets 81, and both mounting brackets 81 are fixedly mounted on the side wall of the processing box 1;

[0068] The pressing roller 82 is rotatably mounted on a side wall adjacent to the two mounting brackets 81 , with the side wall of the pressing roller 82 in contact with the side wall of the outer filter belt 33 and aligned with the side wall of the passing groove 9 ;

[0069] By aligning the pressing roller 82 with the side wall of the through groove 9, the pressing roller 82 can squeeze the side wall of the outer filter belt 33 and guide the outer filter belt 33, making it easier for the outer filter belt 33 to fit the side wall of the inner filter belt 31 and facilitate the outer filter belt 33 to enter the interior of the through groove 9.

[0070] like Figures 1-8 As shown, in one embodiment, a cleaning assembly is provided outside the processing box 1, and the cleaning assembly includes an air pump 51, a connecting groove 54 and a stabilizing frame 57;

[0071] The air pump 51 is fixedly mounted on the top wall of the processing box 1 , and a connecting pipe 52 is fixedly mounted on the output end of the air pump 51 , and the bottom end of the connecting pipe 52 is fixedly mounted inside the positioning pipe 48 ;

[0072] There are multiple communication grooves 54, which are evenly spaced on the side wall of the positioning tube 48. The outer wall of the transmission roller 44 is also evenly spaced with multiple ventilation grooves 55.

[0073] The gas output by the air pump 51 is sent into the interior of the positioning tube 48 through the connecting pipe 52, and is output to the outside through the connecting groove 54 and the ventilation groove 55, and blows on the side walls of the inner filter belt 31 and the outer filter belt 33, blowing off the impurities attached to the side walls of the inner filter belt 31 and the outer filter belt 33, making it easier to clean the inner filter belt 31 and the outer filter belt 33;

[0074] There are multiple stabilizing frames 57, which are fixedly mounted on the side wall of the positioning tube 48. A shielding plate 56 is fixedly mounted on one end of the stabilizing frame 57 away from the positioning tube 48. The shielding plate 56 is in contact with the inner side wall of the transmission roller 44. An exhaust groove 58 is formed on the side wall of the shielding plate 56 away from the processing box 1.

[0075] By fitting the stabilizing frame 57 to the inner wall of the driving roller 44 and cooperating with the exhaust groove 58, the range of the air inside the driving roller 44 blowing outward is limited, while the blowing force is increased, thereby improving the cleaning effect of the airflow on the inner filter belt 31 and the outer filter belt 33.

[0076] like Figures 1-9 As shown, in one embodiment, two collecting assemblies are provided outside the processing box 1, and the collecting assemblies include a collecting box 61 and a fixed rotating shaft 63;

[0077] The collecting box 61 is sleeved on the side wall of the driving roller 44, wrapping the inner filter belt 31 and the outer filter belt 33 therein. A collecting drawer 62 is slidably mounted on the bottom end of the collecting box 61. By wrapping the outer filter belt 33 inside the collecting box 61, impurities on the side walls of the inner filter belt 31 and the outer filter belt 33 can fall into the collecting drawer 62. By pulling out the collecting drawer 62, the impurities can be centrally processed.

[0078] The fixed shaft 63 is rotatably mounted inside the collecting box 61. An air baffle 64 is fixedly mounted on the side wall of the fixed shaft 63. The air baffle 64 is in contact with the side wall of the outer filter belt 33.

[0079] By fitting the air baffle 64 with the side wall of the outer filter belt 33, when the air inside the drive roller 44 is blown out through the exhaust groove 58, it will directly blow on the side wall of the air baffle 64, causing the air baffle 64 to rotate around the fixed rotating shaft 63. When the outer filter belt 33 is aligned with the exhaust groove 58, the air baffle 64 is no longer blown by the air, and rotates around the fixed rotating shaft 63 under the influence of gravity, and hits the side wall of the outer filter belt 33, causing the inner filter belt 31 and the outer filter belt 33 to vibrate, thereby facilitating the falling of impurities on the side walls of the inner filter belt 31 and the outer filter belt 33.

[0080] The specific working method is as follows: exhaust gas is introduced into the interior of the treatment box 1 through the air inlet pipe 2, and the inner filter belt 31 and the outer filter belt 33 are restricted by the groove 9, so that the inner filter belt 31 and the outer filter belt 33 are tightly fitted, and the transverse grooves 32 on the inner filter belt 31 and the longitudinal grooves 34 on the outer filter belt 33 are staggered to form a mesh to filter the exhaust gas. As the inner filter belt 31 and the outer filter belt 33 continue to filter the exhaust gas, impurities in the exhaust gas will block the pores on the inner filter belt 31 and the outer filter belt 33, resulting in a worsening filtering effect. As more and more exhaust gas is stored in the treatment box 1, the air pressure inside the treatment box 1 also increases. The sealing disc 73 moves downward as the air pressure inside the treatment box 1 increases, and the sealing column 75 moves downward as the sealing disc 73 moves downward and contacts the touch switch 78, so that the drive motor 42 starts to work. The drive disc 43 is driven to rotate by the work of the drive motor 42. Under the cooperation of the driven disc 46 and the transmission belt 47, the drive roller 44 is driven to rotate, so that the inner filter belt 31 sleeved on the side wall of the drive roller 44 is rotated, and the clamping block 35 is clamped in the inside of the clamping groove 36, so that the outer filter belt 33 can rotate synchronously with the inner filter belt 31, and the inner filter belt 31 and the outer filter belt 33 located inside the treatment box 1 are pressed. The inner filter belt 31 and the outer filter belt 33 are replaced to ensure their filtration efficiency for exhaust gas. The gas output by the air pump 51 is sent to the interior of the positioning tube 48 through the connecting pipe 52, and is output outwardly through the connecting groove 54 and the ventilation groove 55, and blown on the side walls of the inner filter belt 31 and the outer filter belt 33. The stabilizing frame 57 is fitted with the inner side wall of the transmission roller 44, and with the cooperation of the exhaust groove 58, the range of the air inside the transmission roller 44 to be blown out is limited, and the blowing force is increased at the same time, so that the impurities attached to the side walls of the inner filter belt 31 and the outer filter belt 33 are blown off, which is convenient for cleaning the inner filter belt 31 and the outer filter belt 33. 4 is in contact with the side wall of the outer filter belt 33. When the air inside the driving roller 44 is blown out through the exhaust groove 58, it will directly blow on the side wall of the air baffle 64, causing the air baffle 64 to rotate around the fixed rotation axis 63. When the outer filter belt 33 is aligned with the exhaust groove 58, the air baffle 64 is no longer blown by the air and rotates around the fixed rotation axis 63 under the influence of gravity, and hits the side wall of the outer filter belt 33, causing the inner filter belt 31 and the outer filter belt 33 to vibrate, so that impurities on the side walls of the inner filter belt 31 and the outer filter belt 33 fall off. The impurities are collected by the collection drawer 62, which facilitates centralized treatment of the impurities.

[0081] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacements of the above technical features. Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
